HyACT Mechanism of Action

LOGO



		HyACT-targeted drug delivery vehicle with entrapped anti-cancer drug in the bloodstream after infusion

		HyACT-targeted drug accesses the tumor environment through leaky vasculature typical of vessels that supply blood to tumors. HyACT-targeted drugs form a drug depot in the extracellular space of the tumor

		HyACT-targeted drug binds to activated CD44 and then is rapidly internalized, resulting in more drug entering the tumor cell

		HyACT-targeted drug is transported into an intracellular vesicle and the hyaluronic acid is degraded

		HyACT-targeted drug is released within the cancer cell, increasing the likelihood of cell death and enhanced tumor response

		HyACT-targeted drug depot generally persists for at least 24 hours, resulting in repeated cycles of drug internalization and release inside tumor cells

The figure above is based on preclinical data and the clinical significance is unknown.

Overview

Our lead HyACT product candidate, HA-Irinotecan, is currently in a pivotal Phase III clinical trial for metastatic colorectal cancer, or mCRC. HA-Irinotecan is also in an investigator-sponsored Phase II clinical trial for small cell lung cancer, or SCLC. We also have two other HyACT product candidates that have successfully completed Phase I clinical trials. In addition to our current clinical-stage product candidates, we aim to develop a pipeline of product candidates by exploiting our significant know-how in cancer stem cell biology and cancer metabolism combined with the Versatile Assembly on Stable Templates, or VAST, small molecule drug discovery technology that we will in-license.

Each of our current product candidates combines HyACT with a known anti-cancer drug. HyACT uses hyaluronic acid, or HA, which delivers additional drug to the tumor and promotes uptake of the drug into the tumor cells. HyACT binds to the activated receptor CD44, a naturally occurring HA receptor, which has been shown in numerous studies to be present in high levels in many prevalent solid tumor cancer types but, more importantly, is generally not activated in healthy tissue. CD44 over-expression is associated with more aggressive, metastatic tumors and is also a marker for treatment-resistant cancer stem cells. “Cancer stem cells,” sometimes referred to as tumor-initiating cells, is a term used to describe a small subset of cells within the tumor that, although not actual stem cells, demonstrate stem cell-like characteristics. Cancer stem cells are generally more resistant to current chemotherapy regimens than cancer cells, and their persistence after therapy is thought to be one of the key reasons for disease progression and treatment failure. We believe, based on preclinical studies, that the CD44 receptor-based mechanism has the potential for improving the effectiveness of drugs combining HyACT with an anti-cancer drug, which we refer to as HyACT-targeted drugs. In preclinical studies, HyACT-targeted drugs delivered at least double the dose of anti-cancer drug to the tumor when compared with the drug alone. Our in vitro studies have shown that HyACT significantly increases drug uptake into cancer cells. Finally, preclinical studies have also shown HyACT-targeted chemotherapies are more potent than the original drug at killing cancer stem cells and other CD44-expressing cells.

-1-

treatment regimens. Due to the non-specific nature of current chemotherapeutics, they are typically administered at the maximum tolerated dose, not at the optimal dose required to kill the cancer. As evidenced by the current recurrence and mortality rates associated with cancers, there remains a need to identify new and more effective anti-cancer treatments.

We believe that HyACT is a broadly applicable platform technology that has the potential for enhancing the efficacy of a range of anti-cancer drugs in a number of different cancer indications. In addition to HA-Irinotecan’s Phase II clinical trial data, HyACT-targeted 5-fluorouracil and HyACT-targeted doxorubicin have both demonstrated tolerability and a trend towards efficacy in Phase I / IIa clinical trials. In preclinical studies, we have also had promising results combining HyACT with seven other anti-cancer agents, including other chemotherapies and monoclonal antibodies.

We have considerable know-how, research and preclinical expertise in HA, cancer metabolism, CD44 and cancer stem cells. Prior to the closing of this offering, we will in-license rights to Alchemia Limited’s VAST small molecule drug discovery technology, which provides innovative pyranose compounds for drug discovery. Our strategy is to use these capabilities to investigate new pathways relating to CD44 signaling, HA metabolism and pro-oncogenic pathways that we believe are important to the promotion and proliferation of cancer stem cells. We aim to generate future drugs designed to more effectively target and kill cancer and cancer stem cells.

Our Strategy

Our goal is to build a global biopharmaceutical company focused on the development and commercialization of anti-cancer treatments in the United States and other major markets worldwide. Key elements of our strategy to achieve this objective are:

•

Leveraging our proprietary HyACT technology to bring improved anti-cancer agents to market. Our objective is to use our HyACT technology to improve the delivery of chemotherapeutic agents to cancer cells, boosting drug efficacy without increasing side-effects, thereby increasing the therapeutic index of current chemotherapeutics. We intend to utilize the U.S. Food and Drug Administration, or FDA’s, 505(b)(2) regulatory pathway, which may offer a lower development risk profile and accelerated development compared with completely new cancer drugs.

•

Successfully developing our lead product candidate, HA-Irinotecan, for the treatment of metastatic colorectal cancer. After having consultations with the FDA, we began recruiting patients for a pivotal Phase III clinical trial testing HA-Irinotecan in patients with mCRC in November 2011. If this clinical trial is successful, we intend to seek regulatory approval from both the FDA and the European Medicines Agency, or EMA, of HA-Irinotecan for the treatment of mCRC in the United States and the European Union.

•

Enhancing the commercial value of HyACT-targeted drugs. Where appropriate, we intend to pursue commercialization relationships with pharmaceutical companies and other strategic partners providing for our products to be distributed through their sales and marketing organizations in order to gain access to global oncology markets for any of our product candidates that receive regulatory approval. Over the longer term, we may ultimately build an internal commercial infrastructure to directly market and sell any HyACT-targeted drugs that may receive regulatory approval.

•

Leveraging our expertise and know-how to develop additional anti-cancer agents of high value. Once in-licensed, we plan to utilize our in-licensed small molecule drug discovery technology, VAST, and extensive preclinical expertise in stem cell biology and oncology drug development to develop new therapies targeted at modulating innovative pathways associated with HA metabolism and cancer stem cells.

HyACT

HyACT-targeted product candidates work by exploiting the unique structure and inherent biological properties of HA, a natural glycosaminoglycan polymer, which is a key component of the extracellular matrix in mammals. The specific form of HA used in our HyACT-targeted product candidates combines the effective drug entrapment and delivery properties of HA with the active transport and internalization characteristics resulting from HA’s ability to bind to activated CD44, a receptor generally over-expressed on cancer cells. HA has been shown in preclinical studies to not only carry the anti-cancer drug preferentially to cancer cells but also increase its uptake by those cancer cells.

Our HyACT-targeted product candidates are designed to overcome some of the limitations of current chemotherapies by delivering anti-cancer drugs preferentially to cancer cells in order to increase the response of cancers to standard chemotherapy. Because our initial HyACT-targeted product candidates consist of two FDA-approved agents (HA and chemotherapeutics with well-characterized toxicity and efficacy profiles), we believe that these HyACT-targeted product candidates, which we expect will utilize the FDA’s 505(b)(2) regulatory approval pathway, may offer a lower development risk profile and accelerated development compared with completely new cancer drugs.

Our Product Candidates

Consistent with our strategy, each of our product candidates is being developed for selected cancer therapies to treat specific therapeutically-relevant cancer indications. We have not licensed rights to any of our product candidates to any third parties. The following table summarizes the status of (a) HA-Irinotecan for mCRC and our other product candidates, (b) an investigator-sponsored trial of HA-Irinotecan for SCLC (we do not currently intend to pursue further clinical trials or commercialization of HA-Irinotecan for this indication) and (c) drug discovery activities using the VAST technology:

HA-Irinotecan

Our lead product candidate is HA-Irinotecan for the treatment of mCRC. Irinotecan, which is marketed in major markets by Pfizer as Camptosar, is an off-patent chemotherapy widely used in the treatment of mCRC. In a randomized Phase II clinical trial of HA-Irinotecan compared with irinotecan alone, based on 76 patients with mCRC, HA-Irinotecan was able to double the progression free survival, or PFS, in mCRC patients (5.2 months for HA-Irinotecan versus 2.4 months for irinotecan alone). Based on these findings, we began enrollment for a pivotal Phase III clinical trial, testing HA-Irinotecan in patients with mCRC in November 2011.

In addition to its approved use, published studies suggest that irinotecan may have activity in a range of solid tumors such as those of the breast, pancreas, brain and ovaries. According to reports by Pfizer, sales of Camptosar (proprietary irinotecan, which became generic in 2008) were over $950 million in 2007. We believe that, to the extent clinical trials confirm HA-Irinotecan’s safety and demonstrate significantly improved clinical efficacy compared with irinotecan alone, HA-Irinotecan has the potential to replace irinotecan in first to third line irinotecan-containing treatment regimens.

After having consultations with the FDA, we commenced our pivotal Phase III clinical trial of HA-Irinotecan for the treatment of mCRC. Our Phase III clinical trial is comparing the effectiveness of HA-Irinotecan with irinotecan, both as components of the FOLFIRI chemotherapy regimen (leucovorin, 5-fluorouracil and irinotecan), in 390 irinotecan-naïve, second and third line patients with mCRC. We believe that the FOLFIRI regimen is generally considered the leading standard of care for second and third line treatment for mCRC in the United States and Europe. The primary objective of this study is to demonstrate that HA-Irinotecan provides superior efficacy compared with irinotecan alone, as indicated by a significantly increased period of PFS. As HA-Irinotecan is a formulation of two previously approved products (the cancer drug irinotecan and HA), we intend to utilize an alternative type of New Drug Application, or NDA, commonly referred to as a Section 505(b)(2) NDA, which enables us to rely, in part, on the FDA’s previous approval of a similar product, or on published literature, in support of our application. The 505(b)(2) regulatory approach may enable us to produce an abbreviated preclinical data package, thereby saving development time and costs. If this pivotal trial is successful, we intend to seek regulatory approval from both the FDA and the EMA for HA-Irinotecan for the treatment of second and third line mCRC patients in the United States and the European Union.

In September 2011, recruitment began for an investigator-sponsored Phase II clinical trial of HA-Irinotecan in SCLC. Patients will be randomized to receive either HA-Irinotecan or irinotecan, each in combination with carboplatin. The parameters that will be assessed include safety and measures of efficacy such as PFS. This investigator-sponsored trial has been initiated under the Clinical Trials Notification Scheme, or CTN, of Australia. Approximately 40 first line patients are to be recruited to the trial, which is being conducted at Monash Cancer Centre, Southern Health and Peninsula Oncology Centre in Melbourne, Australia. The primary endpoints for this trial are an efficacy endpoint of the proportion of tumor stem cells remaining after therapy and a safety endpoint of the incidence of grade 3 and 4 toxicity. In addition to these safety and efficacy endpoints, the Phase II clinical trial will measure the additional efficacy endpoints of PFS at six months, objective response rate, survival and the impact of the treatments on circulating tumor cells (the number of cancer cells detected in the blood), an indication of disease progression and prognosis. We are participating in this investigator-sponsored trial primarily because of the potential to further validate the HyACT technology as well as to obtain clinical data on HA-Irinotecan’s activity on cancer stem cells. As this is an investigator-sponsored trial, our involvement in the trial has been limited. We currently do not intend to pursue further clinical trials or commercialization of HA-Irinotecan for the treatment of SCLC and, accordingly, references to our “product candidates” do not include HA-Irinotecan for the treatment of SCLC.

Other HyACT Programs

We used HyACT-targeted 5-fluorouracil in a Phase I / IIa clinical trial in 13 patients with mCRC. We also used HyACT-targeted doxorubicin in a Phase I / IIa clinical trial in 16 patients with metastatic cancer with a life expectancy of at least 12 weeks. We have also conducted preclinical studies that have suggested that HyACT has the potential for improving efficacy of a number of other cancer drugs including gemcitabine (Gemzar), methotrexate (Rheumatrex), carboplatin (Paraplatin) and vinorelbine tartrate (Navelbine). We have also tested in preclinical studies a number of monoclonal antibodies, including bevacizumab (Avastin) and cetuximab (Erbitux), and are investigating the potential of running a parallel clinical trial comparing an HA-monoclonal antibody with the monoclonal antibody alone.

VAST Drug Discovery Technology

In addition to the HyACT platform, prior to the closing of this offering, we will in-license worldwide rights to the VAST small molecule drug discovery technology, which will give us the ability to research and develop new anti-cancer drug candidates. This technology has been deployed in several collaborations with pharmaceutical companies and research institutes exploring its capability and application in non-cancer therapeutic areas. These collaborations are exploiting the chemistry and molecular diversity offered by the VAST technology and diversity scanning array by addressing known targets in an innovative way. We plan to initiate programs to study inflammation pathways associated with cancer stem cells and cancer metabolism with a target involved in HA synthesis. These programs are intended to make use of the selectivity and compound efficiency of the VAST technology. Our VAST programs are run on a business model designed to limit our cash expenditures through the use of partnerships and, if and when available, government grants. These programs include the allosteric modulation of family B G-protein coupled receptors for chronic obstructive pulmonary disease and type II diabetes, as well as opioid receptor agonists and ion channel inhibitors for pain. The collaboration agreements referred to above that are currently in effect are between Alchemia Limited and various collaborators, and any arrangements for government grants relating to the VAST technology are also between Alchemia Limited and the Australian government. We are not a party to any of these collaboration agreements or government grant arrangements, and Alchemia Limited may be required to obtain the consent of its collaborators and the Australian government in order to transfer these collaboration agreements and government grant arrangements to us. If these consents are not granted, it may have a material adverse effect on our ability to exploit the VAST technology. We aim to partner with pharmaceutical and biotechnology companies in areas outside of oncology to validate and commercialize various programs employing the VAST technology in new drug development while progressing certain projects internally.

Risk Factors

Our business is subject to numerous risks and uncertainties, including those highlighted here and described in further detail in “Risk Factors” immediately following this Prospectus Summary and elsewhere in this prospectus. You should carefully read “Risk Factors” for a detailed explanation of some of these risks before investing in our common stock. Some of these risks include the following:

•

we have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable future and we may never achieve or sustain profitability and will require additional funding;

•

we are a clinical-stage company with no approved products, which makes it difficult to assess our future viability;

-5-

•

we are highly dependent on the success of our lead product candidate, the cancer drug HA-Irinotecan for the treatment of mCRC, and we cannot give any assurance that we will successfully complete its clinical development, or that it will receive regulatory approval, or if approved, that it will receive adequate labeling that will allow for successful commercialization for the treatment of mCRC;

•

our proprietary rights may not adequately protect our technologies and product candidates;

•

there is a risk that our development and clinical activities will not result in commercial products, and we will invest in our current development and clinical programs, to the exclusion of others, for several more years before it is known whether one or more of our product candidates will receive regulatory approval, obtain adequate labeling or be commercially introduced;

•

our development activities could be delayed or stopped for a number of reasons, many of which are outside our control, including failure to recruit and enroll patients for clinical trials;

•

the regulatory approval processes of the FDA and non-U.S. regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, or if approved, the labeling is not adequate, our business will be substantially harmed;

•

If our product candidates do not demonstrate superior efficacy in clinical trials, it is unlikely that they will be able to command pricing consistent with proprietary drugs;

•

we will require substantial additional funding which may not be available to us on acceptable terms, or at all;

•

we expect that our stock price will fluctuate significantly, you may not be able to resell your shares at or above the initial public offering price and you may lose all or part of your investment;

•

CHESS Depository Interests, or CDIs, which we expect will represent a majority of our shares of common stock outstanding immediately after this offering, will be listed on the Australian Securities Exchange, will be freely tradable in the public markets in Australia and will begin trading on such exchange on the trading day in Australia following the date of this prospectus, which may have a material adverse effect on the trading price of our common stock on the Nasdaq Global Market; and

•

all of the shares of our common stock to be outstanding following the Demerger and this offering will be freely tradable in the public markets and a number of the shares of our common stock distributed in the Demerger and the CDIs representing those shares will not be subject to lock-up agreements.

Corporate Information

Audeo Oncology, Inc., or Audeo Oncology, the issuer of the common stock to be sold in this offering, was incorporated in Delaware in June 2012 and acquired by Alchemia Limited as a wholly-owned subsidiary. Our principal executive offices are located at 100 Pine Street, Suite 2040, San Francisco, California 94111, and our telephone number is (415) 984-0300. Our website is www.audeooncology.com.

Corporate Reorganization

Our business was in the past conducted through Alchemia Oncology Pty Limited, an Australian company that we sometimes refer to as Alchemia Oncology. Alchemia Oncology, which was previously known as Meditech Research Ltd., was acquired by Alchemia Limited in 2006 and was a wholly-owned direct subsidiary of Alchemia Limited. In June 2012, Alchemia Limited effected a reorganization, which we sometimes refer to as the Reorganization, pursuant to which we became a wholly-owned subsidiary of Alchemia Limited and Alchemia Oncology became a wholly-owned direct subsidiary of ours and a wholly-owned indirect subsidiary of Alchemia Limited. Accordingly, the description of our business and our consolidated financial statements and other financial information included in this prospectus as of the dates and for the periods prior to the Reorganization reflect the business, results of operations and financial position of Alchemia Oncology, and the description of our business and our consolidated financial statements and other financial information as of the dates and for the periods from and after the date of Reorganization reflect the business, results of operations and financial condition of Audeo Oncology, Inc. and its consolidated subsidiaries, in each case unless otherwise expressly stated or the context otherwise requires.

In the past, our business has been financed by Alchemia Limited and, as of March 31, 2012, approximately $27.9 million of related party loans made by Alchemia Limited to us were outstanding. After giving effect to additional loans made to us by Alchemia Limited subsequent to March 31, 2012 (including a loan of approximately $7.5 million made on June 28, 2012), and including effects of foreign currency translation of approximately $0.9 million, a total of approximately $37.6 million of related party loans was outstanding as of June 28, 2012. On June 28, 2012, Alchemia Limited converted all of these related party loans into newly-issued ordinary shares of Alchemia Oncology and, as a result, the loans were cancelled. We subsequently issued 7.5 million shares of our common stock to Alchemia Limited and, in return, Alchemia Limited transferred to us all of Alchemia Oncology’s outstanding ordinary shares in the Reorganization. We sometimes refer to our receipt of the cash proceeds from the additional loan made to us on June 28, 2012, the conversion of all of these outstanding related party loans into newly-issued ordinary shares of Alchemia Oncology and the cancellation of these loans as the Loan Conversion.

The Demerger

Audeo Oncology, Inc., the issuer of the common stock being sold in this offering, is a newly formed Delaware corporation and is currently a wholly-owned subsidiary of Alchemia Limited, an Australian company whose common shares are listed on the Australian Securities Exchange. We were formed for the purpose of (a) acquiring Alchemia Oncology Pty Limited and forming our other subsidiary, Audeo Discovery Pty Limited, an Australian company organized to in-license the VAST small molecule drug discovery technology owned by Alchemia Limited, and (b) demerging from Alchemia Limited as an independent public company with shares of our common stock listed on the Nasdaq Global Market and CHESS Depository Interests, or CDIs, representing shares of our common stock listed on the Australian Security Exchange. Our business and operations consist solely of the business and operations of Alchemia Oncology Pty Limited and Audeo Discovery Pty Limited, both of which are our wholly-owned subsidiaries. Contemporaneously with this offering, we intend to complete our demerger, or the Demerger, from Alchemia Limited pursuant to a Scheme of Arrangement that must be approved by the Federal Court of Australia and by more than 75% in voting interest and a majority in number of Alchemia Limited’s shareholders present and voting at a meeting of shareholders. This meeting of shareholders is anticipated to occur in late September or early October 2012.

rounded upwards to the nearest whole share. To the extent that the number of shares of our common stock currently owned by Alchemia Limited is insufficient to permit the distribution of one share of our common stock for every ordinary shares of Alchemia Limited outstanding at the time of the Demerger, we will issue such number of additional shares of our common stock to Alchemia Limited as may be necessary to permit that distribution to be made in full. As our common stock will not be listed on any Australian stock exchange, Alchemia Limited plans to distribute CDIs representing shares of our common stock to Alchemia Limited shareholders in the Demerger, although those shareholders will have the option of receiving the actual shares of common stock instead. Information in this prospectus assumes that shares of our common stock will be distributed in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012. However, the actual number of shares of our common stock distributed and that will be outstanding upon completion of this offering in the Demerger will be different than the number of shares we have assumed for the purposes of this prospectus, as discussed below under “— The Offering.”

As our common stock will not be listed on any Australian stock exchange, we expect that Alchemia Limited shareholders will generally elect to receive CDIs representing shares of our common stock in the Demerger rather than exercising their option to receive shares of our common stock instead of CDIs. We will deliver the shares of our common stock represented by the CDIs to a depositary, which will hold those shares as trustee on behalf of the holders of the CDIs. Holders of CDIs will have substantially the same economic, voting and other rights as holders of our common stock, and the CDIs therefore should be considered as the functional equivalent of shares of our common stock. We expect that the CDIs will be listed on the Australian Securities Exchange under the symbol “ ” and will begin trading on such exchange on the trading day in Australia following the date of this prospectus. As our common stock will not be listed on any Australian securities exchange, the purpose of the CDIs is to facilitate trading, settlement and clearance in Australia by shareholders of Alchemia Limited who would otherwise receive shares of our common stock in the Demerger. For additional information concerning our CDIs, see “Description of Capital Stock — CHESS Depositary Interests.” This prospectus does not constitute an offer to sell, or the solicitation of an offer to buy, any CDIs or shares of our common stock distributed in the Demerger.

The number of shares of our common stock to be outstanding immediately after this offering as set forth above assumes that shares of our common stock will be distributed to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution of one share of our common stock for every outstanding ordinary shares of Alchemia Limited. However, the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012, and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. As a result, the actual number of shares of our common stock that will be distributed in the Demerger will be different than the number of shares we have assumed for the purposes of this prospectus and the actual number of shares of our common stock that will be outstanding immediately after this offering will be different than the number of shares set forth above. Each share increase (decrease) in the estimated number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger would increase (decrease) the number of shares of our common stock to be issued in the Demerger and to be outstanding immediately after this offering by shares.

-9-

The number of shares of our common stock to be outstanding immediately after this offering excludes:

•

shares of our common stock issuable upon the exercise of warrants, or the Warrants, that we will issue after this offering to investors who purchased ordinary shares of Alchemia Limited in a private placement and that will have an exercise price equal to 130% of the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price for such period as the Average Trading Price). The number of shares of our common stock, or the Warrant Shares, that will be issuable upon exercise of those Warrants will be equal to the quotient obtained by dividing (1) AUD$8,073,000 (equivalent to approximately US$8,066,542 based on the average of the currency exchange rates on November 11, 2011 and December 21, 2011, the dates on which the private placement closed) by (2) 130% of the Average Trading Price. Assuming an Average Trading Price of US$ per share (the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus) and an exchange rate of U.S. dollars for one Australian dollar, approximately Warrant Shares would be issuable upon exercise of the Warrants at an exercise price of approximately US$ per share. However, as the number of Warrant Shares and exercise price both depend upon the actual Average Trading Price following this offering and the number of Warrant Shares also depends upon the exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. For example, a US$1.00 increase (decrease) in the assumed Average Trading Price would decrease (increase) the number of Warrant Shares issuable upon exercise of the Warrants by approximately shares and the exercise price per share by approximately US$ , while a 10% increase (decrease) in the number of U.S. dollars per Australian dollar compared to the assumed exchange rate set forth above would decrease (increase) the number of Warrant Shares issuable upon exercise of the Warrants by approximately shares. In addition, the number of Warrant Shares and/or the exercise price are subject to adjustment pursuant to the terms of the Warrants, including in the event of stock splits, stock combinations and similar events as well as in the event of dividends or other distributions on our shares of common stock. For additional information, see “Description of Capital Stock — Warrants;”

•

options to purchase shares of our common stock that will be granted under our 2012 Equity Incentive Plan concurrently with the closing of this offering at an exercise price per share equal to the initial public offering price per share set forth on the cover page of this prospectus; and

•

additional shares of our common stock reserved for future issuance under our 2012 Equity Incentive Plan, which will become effective in connection with this offering, and additional shares of our common stock that will become available for issuance under our 2012 Equity Incentive Plan pursuant to provisions thereof that automatically increase the number of shares of our common stock reserved for issuance under the plan each year, beginning with our fiscal year commencing July 1, , as more fully described in “Executive Compensation — 2012 Equity Incentive Plan.”

Unless otherwise expressly stated or the context otherwise requires, the information in this prospectus, including the number of shares that will be outstanding immediately after this offering, reflects, assumes and gives effect to the following:

•

the assumed distribution of shares of our common stock in the Demerger (as described above, the actual number of shares of our common stock that are distributed in the Demerger will be different);

•

the filing of our amended and restated certificate of incorporation and the effectiveness of our amended and restated bylaws, which will occur immediately prior to completion of this offering;

-10-

•

no exercise of any options to purchase Alchemia Limited ordinary shares during the period from , 2012 through the record date for the Demerger, as such exercise would increase the number of shares of our common stock distributed in the Demerger;

•

no purchase of shares of our common stock in this offering by existing Alchemia Limited shareholders; and

•

no exercise by the underwriters of their over-allotment option.

Summary Consolidated Financial Data

You should read the following summary consolidated financial data in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes, all included elsewhere in this prospectus. As we are a subsidiary of Alchemia Limited, our consolidated financial statements are derived from the consolidated financial statements and accounting records of Alchemia Limited. Accordingly, our consolidated financial statements include allocations of expenses, primarily salaries and benefits (including stock-based compensation) of officers and other employees of Alchemia Limited, expenses for compensation and reimbursement paid to directors of Alchemia Limited and insurance expenses incurred by Alchemia Limited. These expenses have been allocated based on our estimated share of Alchemia Limited’s expenses. Although we believe that these allocation methodologies are reasonable, the summary consolidated financial information set forth below and our consolidated financial statements do not purport to reflect the results of operations, financial position and cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future.

We derived the summary consolidated statement of operations data for the years ended June 30, 2010 and June 30, 2011 from our audited consolidated financial statements included elsewhere in this prospectus. The summary statement of operations data for the nine months ended March 31, 2011 and March 31, 2012 and the summary consolidated balance sheet data as of March 31, 2012 have been derived from our unaudited interim financial statements included elsewhere in this prospectus. The summary statement of operations data for the period from inception to March 31, 2012 have been derived from our unaudited consolidated financial statements included elsewhere in this prospectus.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risks and all other information contained in this prospectus, including our consolidated financial statements and the related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. If any of the following risks materialize, our business, financial condition, results of operations and prospects could be materially adversely affected. In that case, the trading price of our common stock could decline, and you may lose some or all of your investment.

Risks Related to Our Business and Industry

We have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable future. We may never achieve or sustain profitability and will require additional funding.

We are a clinical-stage biopharmaceutical company with a limited operating history. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are not profitable and have incurred losses and negative cash flow from operations in each year since our inception. We have not generated any revenue from product sales to date. We continue to incur significant research and development and other expenses related to our ongoing operations. Our net loss for the years ended June 30, 2010 and 2011 was approximately $4.0 million and $7.9 million, respectively, and for the nine months ended March 31, 2011 and 2012 was approximately $4.5 million and $5.1 million, respectively. As of March 31, 2012, we had a stockholders’ deficit of $26.7 million. We expect to continue to incur significant losses and negative cash flow from operations for the foreseeable future, and we expect these losses and negative cash flow from operations to increase as we continue to pursue development of, and seek regulatory approvals for, oncology drugs using our HyACT technology, including HA-Irinotecan for the treatment of metastatic colorectal cancer, or mCRC, and begin to commercialize any of those product candidates that may receive regulatory approval, and as we pursue discovery of new drugs using our VAST technology. As a result, we are subject to all of the risks incident to the creation of new drugs and oncology treatments, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. If any of our product candidates fails in clinical trials or does not gain regulatory approval, or if any of our product candidates receives regulatory approval but does not receive adequate labeling or thereafter fails to achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. In addition, we will require additional funding in the future. See the risk factor below entitled “— We will require substantial additional funding which may not be available to us on acceptable terms, or at all.”

We are a clinical-stage company with no approved products, which makes it difficult to assess our future viability.

We are a clinical-stage company, do not have any approved products or products pending approval and therefore have not derived any revenue from the sales of products. Our operations to date have been limited to organizing and staffing our company, acquiring, developing and securing our technology, undertaking preclinical studies and clinical trials of our product candidates and engaging in research. We have not yet demonstrated an ability to obtain regulatory approval, formulate and manufacture commercial-scale products, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, there is limited information about us for investors to use as a basis for assessing our future viability and whether we will be successful in developing our product candidates, conducting clinical trials, obtaining regulatory approvals or commercializing any product candidates for which we may receive regulatory approval.

-16-

We are highly dependent on the success of our lead product candidate, the cancer drug HA-Irinotecan for the treatment of mCRC, and we cannot give any assurance that we will successfully complete its clinical development, or that it will receive regulatory approval, or if approved, that it will receive adequate labeling that will allow for successful commercialization for the treatment of mCRC.

Our lead product candidate, HA-Irinotecan for the treatment of mCRC, has been evaluated in a randomized Phase II clinical trial for the treatment of mCRC, and we recently began enrollment for a Phase III clinical trial. Although enrollment also recently began for an investigator-sponsored Phase II clinical trial for HA-Irinotecan for the treatment of small cell lung cancer, or SCLC, we are participating in this investigator-sponsored trial primarily because of the potential to further validate the HyACT technology and the data on cancer stem cells that it may provide and currently do not intend to pursue further clinical trials or commercialization of HA-Irinotecan for the treatment of SCLC. Our current and future trials may not be successful, and HA-Irinotecan may never receive regulatory approval, or if approved, may not receive adequate labeling that allows for successful commercialization for the treatment of mCRC. We may fail to obtain necessary marketing approvals for HA-Irinotecan for the treatment of mCRC from the U.S. Food and Drug Administration, or FDA, or similar non-U.S. regulatory authorities if our clinical development program for HA-Irinotecan for the treatment of mCRC fails to demonstrate with substantial evidence that it is safe and effective to the satisfaction of such authorities, or if we have inadequate financial or other resources to advance HA-Irinotecan for the treatment of mCRC through clinical trials. Even if HA-Irinotecan for the treatment of mCRC receives regulatory approval, we may not receive adequate labeling for the product or be successful in marketing it for a number of reasons, including the introduction by our competitors of more clinically-effective or cost-effective alternatives or failure of our sales and marketing efforts. Any failure to obtain regulatory approval of HA-Irinotecan for the treatment of mCRC and successfully commercialize it would have a material and adverse impact on our business.

The results of our previous clinical trials may not be predictive of future results, and our current and planned clinical trials may not satisfy the requirements of the FDA or other non-U.S. regulatory authorities.

The clinical trials of our product candidates are, and the manufacturing and marketing of any of our product candidates that may receive regulatory approval will be, subject to extensive and rigorous review and regulation by numerous government authorities in the United States and in other countries where we intend to apply for registration and, if approved, market our product candidates. Before obtaining regulatory approvals for the commercial sale of any product candidate, we must demonstrate through preclinical testing and clinical trials that the product candidate is safe and effective for use in each indication for which we intend to market such product candidate. This process can take many years and requires the expenditure of substantial financial and human resources, may include post-marketing trials and surveillance and ultimately may not prove successful. To date, we have not completed any Phase III clinical trials. We have completed one Phase II randomized clinical trial with HA-Irinotecan for the treatment of patients with mCRC. In addition, we have other product candidates in the discovery and preclinical testing stages.

Positive results from preclinical studies and early-stage clinical trials should not be relied upon as evidence that later-stage or large-scale clinical trials will succeed. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, even after promising results in earlier trials. We will be required to demonstrate with substantial evidence through adequate and well-controlled clinical trials, including our on-going Phase III trial of HA-Irinotecan for the treatment of mCRC, that our product candidates are safe and effective for use in the target population before we can seek regulatory approvals for their commercial sale.

-17-

Our Phase II clinical trial of HA-Irinotecan did not meet its primary endpoint and our Phase III clinical trial of HA-Irinotecan may not be approved even if it achieves its primary endpoint.

Our product candidates may not be approved even if they achieve the primary endpoints in Phase III clinical trials or registration trials. The FDA or non-U.S. regulatory authorities may disagree with our trial design, clinical end points or our interpretation of data from preclinical studies and clinical trials or may change requirements for the approval of our product candidates even after reviewing and providing comment on a protocol for a pivotal Phase III clinical trial that has the potential to result in FDA approval.

Our Phase II clinical trial of HA-Irinotecan for the treatment of mCRC did not meet its primary endpoint of a significant reduction in the incidence of diarrhea and our Phase III clinical trial of HA-Irinotecan for the treatment of mCRC may not be approved even if it achieves its primary endpoint of progression free survival, or PFS. After having consultations with the FDA, we commenced our Phase III clinical trial of HA-Irinotecan for the treatment of mCRC. Because of the difficulty in reliably determining cancer progression based on imaging studies in cancer, the FDA’s policy is to recommend that the primary endpoint for a cancer registration trial be overall survival, or OS, whereas our Phase III clinical trial has PFS as its primary endpoint. If our pivotal Phase III clinical trial is successful, we intend to seek regulatory approval from the FDA of HA-Irinotecan for the treatment of mCRC in the United States; however, such approval, if granted, may not allow us to charge a premium over a generic version of irinotecan and, if that were to occur, we may not be able to successfully commercialize this product, which could have a material adverse effect on our business. We have proceeded with our Phase III trial of HA-Irinotecan for the treatment of mCRC even though our Phase II trial did not meet its primary endpoint of a significant reduction in the incidence of diarrhea. Our Phase III trial of HA-Irinotecan has PFS as its primary endpoint and, even if this trial meets that endpoint, there can be no assurance that the FDA will grant approval based on this trial. The FDA may require an additional trial with OS as a primary endpoint before or after approval. For example, even if our Phase III clinical trial meets its PFS primary endpoint, an additional trial regarding OS could be required as either a pre-approval requirement or as a post-marketing commitment should approval be granted based on PFS. If the FDA were to require a second Phase III clinical trial as a pre-approval requirement, it would substantially increase the time and cost of our development activities and, in any event, may not result in regulatory approval. In addition, if the FDA approves HA-Irinotecan for mCRC based on meeting our PFS primary endpoint but requires post-marketing clinical trials or analyses, the approval could be withdrawn if any required post-marketing trials or analyses do not meet FDA requirements. Any requirement for additional clinical trials following completion of our Phase III trial of HA-Irinotecan would substantially increase our costs and could have a material adverse effect on our business, results of operations and prospects.

There is a risk that our development and clinical activities will not result in commercial products, and we will invest in our current development and clinical programs, to the exclusion of others, for several more years before it is known whether one or more of our product candidates will receive regulatory approval, obtain adequate labeling or be commercially introduced.

Our product candidates are in various stages of development and are prone to the risks of failure inherent in biopharmaceutical development. We will need to complete significant additional clinical trials demonstrating that our product candidates are safe and effective to the satisfaction of the FDA and other non-U.S. regulatory authorities. Pursuit of our drug discovery activities and clinical programs are costly, time consuming and of uncertain outcome. Failure can occur at any stage of the process. If such programs are not successful, we may invest substantial amounts of time and money without developing revenue-producing products. As we enter a more extensive clinical program in several different diseases, the data generated in these studies may not be as compelling as the earlier results. Further, even if our product candidates receive required regulatory approvals, we cannot assure you that they will be successful commercially. In addition, we have a number of product candidates in our development pipeline, and while we invest in the technology and indications that we believe are most promising, financial and resource constraints may require us to forego or delay opportunities that may ultimately have greater commercial potential than those programs we are currently actively developing or choose

-18-

to actively develop in the future. There is no assurance that product candidates developed using our technology will prove to be safe and efficacious in clinical trials, or that the regulatory approval to manufacture and market our product candidates will be received, or if received, that such regulatory approval will result in a commercially viable product. Product candidates utilizing our technology may be shown to be unsafe, non-efficacious, difficult or impossible to manufacture on a large scale, uneconomical to market, compete with superior products marketed by third parties or not be as attractive as alternative treatments.

Our development activities could be delayed or stopped for a number of reasons, many of which are outside our control, including failure to recruit and enroll patients for clinical trials.

Clinical trials of promising product candidates can take years, the duration depending on, among other factors, type, complexity, novelty and intended use of the product candidate. We do not know whether our current clinical trials will be completed on schedule, or at all, and we cannot guarantee that our future planned clinical trials will begin on time, or at all. Our current and planned clinical trials could be substantially delayed or prevented by several factors, including:

•

limited number of, and competition for, suitable sites to conduct our clinical trials;

•

government or regulatory delays and changes in regulatory requirements, policy and guidelines;

•

delay or failure to obtain sufficient supplies of the product candidate for our clinical trials as a result of non-compliance with regulatory requirements, including current Good Manufacturing Practice, or GMP, by our suppliers or for other reasons;

•

delay or failure to reach agreement on acceptable clinical trial agreement terms with prospective sites or investigators;

•

failure to obtain required regulatory approvals;

•

delay or failure to obtain institutional review board, or IRB, approval to conduct a clinical trial at a prospective site;

•

slower than expected rates of patient recruitment and enrollment;

•

variability in the number and types of patients available for each study;

•

unforeseen safety issues or side effects;

•

lack of efficacy evidenced during clinical trials, which risk may be heightened given the advanced state of disease and lack of response to prior therapies of patients in our clinical trials for HA-Irinotecan;

•

termination or delays of our clinical trials by an IRB at one or more institutions assisting us with our clinical trials;

•

adding new clinical trial sites;

•

inability or unwillingness of patients or medical investigators to follow our clinical trial protocols, or medical investigators and their staff to comply with Good Clinical Practices, or GCPs;

•

difficulty in maintaining contact with patients after treatment, resulting in incomplete data; and

inability to monitor patients adequately during or after treatment or high patient dropout rates.

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating. Furthermore, we rely on contract research organizations and clinical trial sites to ensure the proper and timely conduct of our clinical trials and while we typically enter into agreements governing the activities that they conduct for us, we have limited influence over their actual performance.

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials are being conducted, by the Data Safety Monitoring Board for such trial or by the FDA or other regulatory authorities. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate revenues from any of these product candidates will be delayed or terminated. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that could cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

The regulatory approval processes of the FDA and non-U.S. regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, or if approved, the labeling is not adequate, our business will be substantially harmed.

The research, development, manufacture, marketing and sale of product candidates using our technology are subject to extensive regulation by a number of government authorities, particularly the FDA. The time required to obtain approval by the FDA and non-U.S. regulatory authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. We have not submitted for nor obtained regulatory approval for any product candidate and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain regulatory approval.

The regulatory approval process is inherently subject to risks, including that approval will not be granted, approval may not support commercial launch or approval may be subject to unforeseen delay or may be subject to onerous conditions which may adversely impact our ability to achieve our objectives. Our product candidates could fail to receive regulatory approval for many reasons, including the following:

•

the FDA or non-U.S. regulatory authorities may disagree with the design or implementation of our clinical trials or study endpoints;

•

we may be unable to demonstrate to the satisfaction of the FDA or non-U.S. regulatory authorities that a product candidate is safe and effective for its proposed indication or that our product candidates provide significant clinical benefits;

•

the results of clinical trials may not meet the level of statistical significance required by the FDA or non-U.S. regulatory authorities for approval or may not support approval of a label that could command a pricing premium compared to a generic product;

-20-

•

we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;

•

the FDA or non-U.S. regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;

•

the data collected from clinical trials of our product candidates may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere;

•

the FDA or non-U.S. regulatory authorities may fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and

•

the approval policies or regulations of the FDA or non-U.S. regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.

We may be unable to secure necessary approvals from regulatory agencies and institutional bodies (including clinics and hospitals) to conduct clinical trials. The lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market HA-Irinotecan for the treatment of mCRC or our other product candidates, which would materially harm our business, results of operations and prospects. To date, we have not filed for marketing approval for any of our product candidates and may not receive the approvals necessary to successfully commercialize our product candidates in any market. The failure to obtain regulatory approval or approval with a label that will allow for a pricing premium compared with a generic product in any jurisdiction could materially harm our business and may have a negative effect on the regulatory approval process in other jurisdictions.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our product candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the foregoing could materially harm the commercial prospects for our product candidates.

If our product candidates do not demonstrate superior efficacy in clinical trials, it is unlikely that they will be able to command pricing consistent with proprietary drugs.

We believe that HA-Irinotecan for the treatment of mCRC, if it receives regulatory approval, has the potential of commanding pricing consistent with proprietary drugs. However, this is dependent upon HA-Irinotecan for mCRC demonstrating superior efficacy in clinical trials, and we cannot assure you that this will occur. If it does not occur, the pricing for HA-Irinotecan for the treatment of mCRC may be substantially lower than we anticipate, which could have a material adverse effect on our business, operating results or financial condition.

We may not obtain approval to market our product candidates outside the United States or negotiate satisfactory pricing for our product candidates in foreign jurisdictions, which could adversely impact our future profitability.

We intend to seek approval to market certain of our product candidates in both the United States and in non-U.S. jurisdictions. In order to market our product candidates in the European Union and many other non-U.S. jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. To date, we have not filed for marketing approval for any of our product candidates and

-21-

may not receive the approvals necessary to successfully commercialize our product candidates in any market. The approval procedure varies among countries and can involve additional testing and data review. The time and safety and efficacy data required to obtain non-U.S. regulatory approval may differ from that required to obtain FDA approval. The non-U.S. regulatory approval process will include all of the risks associated with obtaining FDA approval. We may not obtain non-U.S. regulatory approvals on a timely basis, or at all. Approval by the FDA does not ensure approval by regulatory agencies in other countries, and approval by one non-U.S. regulatory authority does not ensure approval by regulatory agencies in other countries or by the FDA. However, a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in other jurisdictions, including approval by the FDA. The failure to obtain regulatory approval in any jurisdiction could materially harm our business.

Even if we receive regulatory approval for any of our product candidates, we will be subject to ongoing obligations and continued regulatory review, which will result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with any of our product candidates that receive regulatory approval.

Any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses or comparative statements for which the product candidates may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including post-marketing clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA or a non-U.S. regulatory authority approves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product candidate will be subject to extensive and ongoing regulatory requirements. These requirements will include submissions of safety and other post-marketing information and reports and registration, as well as continued compliance with current Good Manufacturing Practices, or cGMPs, and GCPs, for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product recalls;

•

fines, warning letters, adverse publicity or holds on clinical trials;

•

refusal by the FDA or similar non-U.S. regulatory authorities to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license approvals;

•

product seizure or detention, or refusal to permit the import or export of products; and

•

injunctions or the imposition of civil or criminal penalties.

The policies of the FDA or similar non-U.S. regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

The coverage and reimbursement status of newly approved pharmaceuticals is uncertain, and failure to obtain adequate coverage and adequate reimbursement of HA-Irinotecan or other product candidates could limit our ability to generate revenue.

There is significant uncertainty related to the third-party coverage and reimbursement of newly approved drugs. The commercial success of our product candidates, including HA-Irinotecan, in both domestic and international markets will depend in large part on the availability of coverage and adequate reimbursement from third-party payors, including government payors such as the Medicare and Medicaid programs and managed care organizations, and may be affected by existing and future health care reform measures. Government and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new drugs and, as a result, they may not cover or provide adequate payment for our product candidates. Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of our products to the payor. We may not be able to provide data sufficient to gain acceptance with respect to adequate coverage and reimbursement. These payors may conclude that our product candidates are less safe, less effective or less cost-effective than existing or later introduced products, and third-party payors may not approve our product candidates for coverage and reimbursement or may cease providing or provide inadequate coverage and reimbursement for these product candidates. As there is a large number of both governmental and third-party payors, obtaining coverage reimbursement in the United States and internationally will likely take significant time and cause us to spend significant resources. We also anticipate that we will need to provide substantial evidence to payors that HA-Irinotecan for the treatment of mCRC, if approved, provides superior efficacy compared with generic irinotecan before these payors will be willing to pay a price for our drug that is greater than the price for generic irinotecan. There can be no assurance that our clinical data will allow for premium pricing of HA-Irinotecan. The failure to obtain coverage and adequate reimbursement for our product candidates or healthcare cost containment initiatives that limit or deny reimbursement for our product candidates may materially and adversely affect our business.

In the United States and in other countries, there have been and we expect there will continue to be a number of legislative and regulatory proposals to change the healthcare system in ways that could significantly and adversely affect our business. International, federal and state lawmakers regularly propose and, at times, enact legislation that would result in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. The U.S. government and other governments have shown significant interest in pursuing healthcare reform, as evidenced by the passing of the Patient Protection and Affordable Care Act and its amendment, the Health Care and Education Reconciliation Act. Such government-adopted reform measures may adversely impact the pricing of healthcare products and services in the United States or internationally and the amount of reimbursement available from governmental agencies or other third-party payors. In addition, in some foreign jurisdictions, there have been a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our product candidates (if approved) profitably. The continuing efforts of U.S. and other governments, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce healthcare costs may adversely affect the prices we are able to charge for our product candidates, if approved, and our ability to generate revenues and achieve and maintain profitability.

In some countries, particularly in the European Union, prescription drug pricing is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product candidate. To obtain reimbursement or pricing approval in some countries, we may be required to conduct additional clinical trials that compare the cost-effectiveness of our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount in a particular country, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability of our product candidates in such country.

-23-

Even if we are able to obtain regulatory approval of HA-Irinotecan in the treatment of mCRC, marketing will be limited by the intended indication and the potential size of the market.

Even if we are able to obtain regulatory approval of HA-Irinotecan based on our Phase III clinical trial for mCRC and formulate and manufacture a commercial-scale product, our marketing of HA-Irinotecan will be limited to our initial intended indication of mCRC and not cancer generally, or any other type of cancer. Our marketing claims may also be limited in the comparison statements we can make to irinotecan.

According to the American Cancer Society, approximately 143,000 new cases of colorectal cancer are expected to be reported in the United States in 2012, with approximately 51,000 patients in the United States expected to die from colorectal cancer in 2012. Marketing of HA-Irinotecan, if approved for our intended indication, will be limited to those people with mCRC. Marketing efforts for HA-Irinotecan outside of our approved indications will require additional regulatory approvals, which we may never pursue or receive. In addition, we cannot guarantee that we will recover the cost of developing HA-Irinotecan or any of our other product candidates from any future commercial sales.

Our product candidates may cause undesirable side effects that could delay or prevent their regulatory approval or commercialization.

As our HyACT product candidates have been tested in relatively small patient populations and for limited durations to date, additional side effects may be observed as their development progresses. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims.

Undesirable side effects caused by any of our product candidates could cause us or regulatory authorities to interrupt, delay or discontinue clinical trials and could result in the denial of regulatory approval by the FDA or non-U.S. regulatory authorities for any or all targeted indications. This, in turn, could prevent us from commercializing our product candidates and generating revenues from their sale. In addition, if one of our product candidates receives marketing approval and we or others later identify undesirable side effects caused by this product candidate:

•

regulatory authorities may withdraw their approval of this product;

•

we may be required to recall this product, change the way this product is administered, conduct additional clinical trials or change the labeling of this product in a way that significantly narrows the indications for use;

•

we could be sued and held liable for harm caused to patients;

•

this product may be rendered less competitive and sales may decrease; or

•

our reputation may suffer generally both among clinicians and patients.

Any one or a combination of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate or could substantially increase the costs and expenses of commercializing the product candidate, which in turn could delay or prevent us from generating significant revenues from the sale of the product candidate.

-24-

We will require substantial additional funding which may not be available to us on acceptable terms, or at all.

We are advancing multiple product candidates through clinical development. Our cash flow from operations has been and continues to be negative, we have no credit facility or other committed source of external financing and our cash, cash equivalents and working capital are limited. Accordingly, we are and will be entirely dependent upon external financing to fund our cash needs and, even after giving effect to our receipt of the estimated net proceeds from this offering, we will need to raise substantial additional capital to continue our clinical development and preparing for commercialization activities. In particular, we will need to raise additional capital if the proceeds from this offering are insufficient to fund the current Phase III clinical trial of HA-Irinotecan for the treatment of mCRC, the current investigator-sponsored Phase II clinical trial for HA-Irinotecan for the treatment of SCLC, and the further costs, which we expect will be significant, of seeking regulatory approval for HA-Irinotecan for the treatment of mCRC if our Phase III clinical trial is successful or if the FDA requires further clinical trials with respect to HA-Irinotecan for the treatment of mCRC. We will also need to raise substantial additional capital in order to proceed with the clinical development of, and seek regulatory approval for, any of our other product candidates. In addition, our VAST small molecule drug discovery technology currently relies on partnerships with pharmaceutical and biotechnology companies and on collaborations with academic groups and in the past has relied and in the future may rely on government grants, if available, and if Alchemia Limited is unable to assign these collaboration agreements and grant arrangements to us as described below or if those partnerships or collaborations terminate or if we are unsuccessful in obtaining future grants, we may need to find alternative sources of funding to further our drug discovery initiatives. There is no guarantee that we would be successful in obtaining any such funding on terms that we deem acceptable, or at all. In addition, as discussed below under the risk factor titled “Alchemia Limited may be unable to transfer its rights under collaboration agreements and government grant arrangements relating to the VAST technology to us,” there is also no guarantee that Alchemia Limited will be able to transfer its collaboration agreements and current grant funding arrangements relating to the VAST small molecule drug discovery technology to us, which may have an adverse affect on our funding.

Moreover, we have to date relied entirely upon Alchemia Limited, our parent corporation, for all of the funds necessary to conduct our research and development activities and operate our business. Alchemia Limited has provided these funds to us through loans, all of which Alchemia Limited converted to newly-issued ordinary shares of Alchemia Oncology prior to the date of this preliminary prospectus. Alchemia Limited has no obligation to provide us with financing following this offering and we understand that Alchemia Limited has no intention of doing so. We have no experience raising debt or equity financing from third parties and there can be no assurance that we will be able to do so on terms we deem acceptable, or at all.

The timing and amount of any future funding requirements will depend on many factors, including but not limited to:

•

our need to expand our research and development activities;

•

the rate of progress and cost of our clinical trials and the need to conduct clinical trials beyond those currently planned;

•

the costs associated with establishing a sales force and commercialization capabilities, if any of our product candidates receives regulatory approval;

•

the costs of acquiring, licensing or investing in businesses, product candidates and technologies;

•

the costs and timing of seeking and obtaining approval from the FDA and non-U.S. regulatory authorities;

•

our ability to maintain, defend and expand the scope of our intellectual property portfolio;

•

our need and ability to hire additional management and scientific and medical personnel;

-25-

•

the effect of competing technological and market developments;

•

our need to implement additional internal systems and infrastructure, including financial and reporting systems appropriate for a public company;

•

the economic and other terms and timing of collaboration, licensing or other arrangements into which we may enter; and

•

uncertainties regarding our ability to continue and maintain collaborations with pharmaceutical and biotechnology companies and collaborations with academic groups.

Until we can generate a sufficient amount of revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through public or private equity or debt financings, any strategic collaborations we may enter into and any future government grants we may receive. We do not know whether additional funding, collaborations or grants will be available on acceptable terms, or at all, and we may not be able to raise funds as and when they are required. If we are not able to secure additional funding when needed, we may have to:

•

delay, reduce the scope of or eliminate one or more of our clinical trials or research and development programs, including our VAST small molecule drug discovery technology;

•

enter into collaboration or other arrangements with other companies to provide such funding in exchange for our affording such partner commercialization or other rights to our product candidates, any products of ours that may receive regulatory approval, or other intellectual property or other assets;

•

license or sell our technologies on unfavorable terms; or

•

scale down or cease operations.

Alchemia Limited may be unable to transfer its rights under collaboration agreements and government grant arrangements relating to the VAST technology to us.

In connection with this offering, we will in-license the VAST small molecule drug discovery technology from Alchemia Limited. The VAST technology currently relies on Alchemia Limited’s collaborations with pharmaceutical and biotechnology companies and academic groups and has relied and in the future may rely on grants from the Australian government. We are not a party to any of these collaboration agreements or government grant arrangements and Alchemia Limited may be required to obtain the consent of its collaborators and the Australian government in order to transfer these collaboration agreements and government grant arrangements to us. There can be no assurance that these consents will be granted and, if they are not, it may have a material adverse effect on our ability to exploit the VAST technology and we may not receive the support provided by these collaborations and the additional funding potentially available under these government grant programs. Moreover, the license agreement pursuant to which we will in-license the VAST technology requires that we make certain minimum annual expenditures to exploit the VAST technology. If we do not receive the benefit of these collaborations and government grant arrangements, it may lessen our incentive to meet these annual expenditure requirements, which could result in a revocation of the VAST in-license by Alchemia Limited.

-26-

Raising additional capital may cause dilution to existing stockholders, restrict our operations, encumber our intellectual property or other assets or require us to relinquish rights.

We may seek the additional capital necessary to fund our operations through public or private equity or debt financings, and collaborative and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted and the terms of those securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures, or declaring dividends, or which impose financial covenants on us that limit our operating flexibility to achieve our business objectives. Likewise, we may be required to pledge some or all of our intellectual property or other assets to secure debt financing and, in the event we fail to comply with financial or other covenants in debt agreements or certain specified events of default occur, the lenders will typically be permitted to demand immediate repayment of all amounts that we have borrowed and, in the case of secured indebtedness, to seize and sell the collateral to repay that indebtedness. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us. In addition, we cannot assure you that additional funds will be available to us on favorable terms or at all.

We may be required to repay our government grant from the Australian government or any future grants that we receive.

We received a research grant from the Australian government under the Commercial Ready Grant for our HA-Irinotecan program. The total amount of grants received since the commencement of the Commercial Ready Program is approximately $1.7 million. The Australian government may require us to repay some or all of the grants we have received from them in the past or that we may receive from them in the future, together with interest, under specified circumstances. For example, we may be required to repay our past grants if we fail to use our best endeavors to commercialize the relevant grant project within a reasonable time of completion of the project, upon termination of the grant due to our breach of the agreement or insolvency, upon a change in control or ownership of our company that the Australian government reasonably considers to have an adverse effect on our ability to comply with any of our obligations in the grant agreement or if we cease to carry on a substantial part of our business.

We rely on third parties to manufacture and supply both the active pharmaceutical ingredients used in our HyACT product candidates and finished drug products, and our commercialization of any of our product candidates could be stopped, delayed or made less profitable if those third parties fail to obtain or maintain the approval of the FDA or non-U.S. regulatory authorities, fail to provide us with sufficient quantities of active pharmaceutical ingredients or drug product or fail to do so at acceptable quality levels or prices.

We do not manufacture, formulate or package any of our product candidates, except for small quantities used in preclinical studies and clinical trials that are manufactured for us by third parties. We do not currently own or operate manufacturing facilities for clinical or commercial production of our product candidates, and we are reliant on third parties for such activities. We have limited experience in drug formulation or manufacturing, and we lack the resources and the capability to manufacture any of our product candidates on a clinical or commercial scale. The facilities used by our contract manufacturers to manufacture both the active pharmaceutical ingredients, or API, used in our HyACT product candidates and finished drug products must be inspected and approved by the FDA pursuant to inspections that will be conducted after we submit our NDA to the FDA. Likewise, similar approvals are required by non-U.S. regulatory authorities. We do not control the manufacturing process of, and are completely dependent on, our contract manufacturing partners for compliance with the regulatory requirements, known as cGMPs, for manufacture of both API and finished drug products. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the

-27-

strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a non-U.S. regulatory authority does not approve these facilities for the manufacture of both the API and finished drug products or if it withdraws any such approval in the future, we would need to find alternative manufacturing facilities, which must be approved by regulatory authorities before we can use them, and which would significantly limit our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Likewise, we may suffer significant delays and expenses in transitioning manufacturing to another facility or supplier. If any of our product candidates receives regulatory approval and we seek to manufacture commercial quantities of that product candidate, the ability of our contract manufacturers to produce commercial quantities will be subject to risks similar to those described above.

If for some reason our contract manufacturers cannot perform as agreed, we may be unable to replace them in a timely manner and the production of our product candidates would be interrupted, resulting in delays in clinical trials and additional costs. Switching manufacturers may be difficult because the number of potential manufacturers is limited and the FDA and similar non-U.S. regulatory authorities, if applicable, must approve any replacement manufacturer prior to manufacturing our product candidates. Such approval would require new testing and compliance inspections. In addition, a new manufacturer would have to be educated in, or develop substantially equivalent processes for, production of our product candidates and the API used in those product candidates after receipt of FDA or non-U.S. regulatory approval to manufacture any of our product candidates. It may be difficult or impossible for us to find a replacement manufacturer on acceptable terms quickly, or at all.

To date, our product candidates and the API used in those product candidates have been manufactured in small quantities for preclinical studies and clinical trials by third-party manufacturers. If the FDA or other regulatory authorities approve any of our product candidates for commercial sale, we expect that we would continue to rely on third-party manufacturers to produce commercial quantities of our approved product candidates and the API used in those product candidates. These manufacturers (including the manufacturer that has agreed to act as our exclusive supplier of commercial quantities of HA as described below) may not be able to successfully build or increase the manufacturing capacity for any of our approved product candidates or the API used in those product candidates in a timely or economic manner, or at all. Newly constructed manufacturing facilities must be approved by the FDA and applicable non-U.S. regulatory authorities, and significant scale-up of manufacturing may require additional validation studies, which the FDA and any other applicable regulatory authorities must review and approve. Additionally, any third-party manufacturer we retain to manufacture our product candidates on a commercial scale must pass an FDA pre-approval inspection for conformance to the cGMPs before we can obtain approval of our product candidates and similar approvals are required by various non-U.S. regulatory authorities. If our third party manufacturers are unable to successfully increase the manufacturing capacity for a product candidate in conformance with cGMPs and similar requirements of applicable non-U.S. regulatory authorities, the regulatory approval or commercial launch of such product candidates may be delayed or there may be a shortage in supply.

We have entered into a supply agreement with Novozymes Biopharma DK A/S, or Novozymes, whereby we agree to use Novozymes as our exclusive supplier of HA if our HA-Irinotecan product candidate receives regulatory approval. Novozymes does not have the manufacturing capacity to supply the quantities of HA called for by the agreement and, although it has agreed to use commercially reasonable endeavors to build and maintain sufficient manufacturing capacity to supply us with HA pursuant to this agreement, there can be no assurance that it will be able to do so. Likewise, even if Novozymes builds sufficient manufacturing capacity, its ability to supply us with HA in commercial quantities is subject to approval of those facilities by the FDA and non-U.S. regulatory authorities and the other risks described in this risk factor. To the extent that Novozymes is unable to supply commercial quantities of HA for our HA-Irinotecan product candidate, if it receives regulatory approval, it may have a material adverse effect on our business, results of operations and financial condition. For additional information about this supply agreement, see “Business—Manufacturing.”

-28-

Our product candidates require precise, high quality manufacturing. Failure by our contract manufacturers to achieve and maintain high manufacturing standards could result in patient injury or death, product recalls or withdrawals, adverse publicity, delays or failures in testing or delivery, cost overruns, or other problems that could seriously harm our business. Contract manufacturers may encounter difficulties involving production yields, quality control and quality assurance.

We rely on our manufacturers to purchase from third-party suppliers the materials necessary to produce our product candidates for our clinical trials. There are a limited number of suppliers for raw materials that are used to manufacture our drugs and there may be a need to assess alternate suppliers to prevent a possible disruption in supply of the materials necessary to produce our product candidates for our clinical trials, and if approved, ultimately for commercial sale. We do not have any control over the process or timing of the acquisition of these raw materials by our manufacturers. Although we generally do not begin a clinical trial unless we believe we have a sufficient supply of a product candidate to complete the clinical trial, any significant delay in the supply of a product candidate, or the raw material components thereof, for an ongoing clinical trial could considerably delay completion of our clinical trials, product testing and potential regulatory approval of our product candidates. If our manufacturers or we are unable to purchase these raw materials after regulatory approval has been obtained for our product candidates, the commercial launch of our product candidates would be delayed or there would be a shortage in supply, which would impair our ability to generate revenues from the sale of our product candidates.

We expect to continue to depend on third-party contract manufacturers for the foreseeable future. Apart from our agreement with Novozymes, we have not entered into long-term agreements with any contract manufacturers or with any alternate suppliers, and, although we intend to do so prior to commercial launch if any of our product candidates is approved, we may be unable to enter into such an agreement or do so on commercially reasonable terms, which could have a material adverse impact upon our business. We currently obtain our supplies of finished drug product through individual purchase orders. There can be no guarantee that such third parties will continue to supply us with our product candidates and the API used in those product candidates, or that their manufacturing facilities will remain at the appropriate standard. Any performance failure on the part of current or future third party manufacturers could delay clinical development, marketing approval or, if any of our product candidates are approved, commercialization of our product candidates. Our current and anticipated dependence on others for the manufacture of our product candidates or products may adversely affect our results of operations and our ability to commercialize any product candidates that receive market approval.

A shortage in the supply of the anti-cancer drugs used in our product candidates could increase our costs and adversely affect our ability to commercialize any of our product candidates.

The anti-cancer drugs used in our product candidates have from time to time been in short supply and, because many or all of these anti-cancer drugs are also widely used in cancer treatment currently, we will compete with a broad range of healthcare providers and other companies for the supply of those drugs. Any shortage of the drugs used in our product candidates could adversely affect our ability to timely conduct preclinical studies and clinical trials and, if any of those product candidates receives regulatory approval, to commercialize those products and also may result in an increase, which could be significant, in our costs of procuring those drugs.

If we do not establish development or commercialization collaborations, we may have to alter our development and marketing plans.

Our development programs and potential commercialization of our product candidates, if approved, will require substantial additional cash. We may need to enter into collaborative agreements to develop and, if approved, we will likely seek to enter into collaborations to market HA-Irinotecan product candidates from our HyACT platform. These collaborations may require us or our partners to undertake or fund certain research and

-29-

development activities and may require our partners to make payments to us on achievement of certain milestones and pay royalties or make profit-sharing payments to us when and if a product candidate is marketed. As of June 2012, our strategy included current collaborations with the University of Queensland and Monash Institute of Pharmaceutical Sciences (both located in Australia) for pursuit of our VAST small molecule drug discovery technology and we expect to seek additional collaborations with other research institutions and pharmaceutical and biotechnology companies to assist us in furthering development and potential commercialization of some of our product candidates in the United States or internationally. The collaborations described above include gross-revenue sharing based on the financial contribution of each party at the point of sub-licensing and any future research collaborations may include similar revenue sharing arrangements, while we expect that any collaborations we enter into with a pharmaceutical or biotechnology company may provide for us to receive upfront, research and development, milestone or royalty payments or some combination thereof. We may seek to enter into collaborations in the future, especially for target indications in which the potential collaborator has particular therapeutic expertise or for markets outside of the United States.

The success of our collaborations may depend on the resources devoted to them by us or our partners. There is no certainty that we will attract appropriate strategic partners or collaborators, that we will be able to enter into agreements with strategic partners or collaborators on terms we find acceptable, or at all, or that any goals, arrangements or payments contemplated by any agreements we do enter into will be achieved or made. We face significant competition in seeking appropriate collaborators and these collaborations are complex and time-consuming to negotiate and document. Collaborative agreements may be terminable by our industry partners, and we may not be able to negotiate collaborations on acceptable terms, or at all. If that were to occur, we may have to curtail the development of product candidate, reduce or delay its development or one or more of our other development programs or, in the case of any product candidate for which regulatory approval is received, delay its potential commercialization, reduce the scope of our sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we will likely need to obtain additional capital, which may not be available to us on acceptable terms, or at all. If we do not have sufficient funds, we will not be able to continue our clinical trials, preclinical studies and VAST small molecule drug discovery projects or bring to market any of our product candidates that receive regulatory approval and generate revenue. In addition, we cannot assure you that the objectives of our existing or future development or commercialization arrangements will be realized or that the arrangement will not be terminated or expire. Suspension or termination of collaborative agreements, or the failure to enter into appropriate collaborative arrangements, may have a material adverse impact on our business, financial condition and results of operations.

If our competitors develop and market products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted. In addition, all of our current product candidates are combinations of HA and existing cancer drugs and will likely face continued competition from those existing drugs used alone and in alternative treatment regimens.

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our technology, clinical development experience and scientific knowledge provide us with competitive advantages, we face competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing treatment regimens and new treatment regimens that may become available in the future.

There are a number of companies that carry out some form of competitive activities. Competitive activities could include developing reformulations of irinotecan and other anti-cancer drugs for use in oncology applications, exploiting HA as a therapeutic, researching and developing product candidates from applied research on cancer stem cells, and conducting late stage clinical development for application in colorectal cancer. Our lead product candidate is HA-Irinotecan for the treatment of mCRC and the following table shows potential competitors with drugs in late stage clinical development for mCRC as of June 28, 2012:


Company	Drug Name	Stage of Development
Bayer-Schering	regorafenib	Filed
Sanofi/Regeneron	aflibercept	Filed
Light Sciences Oncology	talaporfin sodium	Phase III
Nektar Therapeutics	PEG-irinotecan	Phase II

We are aware of a potential competitor, Nektar Therapeutics, or Nektar, which is developing a suite of new chemical entities with modified pharmacokinetic profiles through the pegylation of known therapeutic agents. For instance Nektar’s product candidate is a pegylated version of irinotecan that is being assessed in a variety of cancers, including a Phase III clinical trial in metastatic breast cancer and two Phase II clinical trials in mCRC and platinum resistant ovarian cancer. In addition, Merrimack Pharmaceuticals, Inc., or Merrimack, is developing a new formulation of irinotecan for application in pancreatic cancer. Having completed a Phase II clinical trial in May 2011, Merrimack recently initiated a Phase III clinical trial for the same indication. Merrimack also has a Phase II clinical trial and two Phase I clinical trials in oncology indications ongoing. Companies working on cancer stem cells include Boston Biomedical, Inc. (acquired by Dainippon Sumitomo Pharma Co., Ltd.), OncoMed Pharmaceuticals, Inc., Stemline Therapeutics, Inc. and Verastem, Inc.

Other companies are or may be developing, and in the future may develop, drugs for the treatment of indications targeted by HA-Irinotecan for the treatment of mCRC and our other product candidates.

It is possible that competitors may develop new products in our target market before we are able to develop such products. It is also possible that our competitors may establish licensing agreements with large multinational pharmaceutical companies in our target markets before we are able to establish such licensing arrangements. Furthermore, it is possible that one or many competing products will achieve FDA approval before HA-Irinotecan for the treatment of mCRC or any of our other product candidates, which may limit our ability to successfully commercialize HA-Irinotecan for the treatment of mCRC, if approved, or any of our other product candidates which may receive regulatory approval.

The VAST technology is a chemistry platform that provides innovative pyranose compounds for drug discovery, with competition anticipated from other drug discovery companies with novel chemistries. For instance, we are aware of companies, including Ensemble Therapeutics, Summit PLC and Tranzyme Pharma, that all have innovative chemistry platforms. Summit PLC has a small carbohydrate library based on imino sugar scaffolds which offer unique activities predominantly in carbohydrate modification pathways. Ensemble Therapeutics and Tranzyme Pharma use macrocyclic technology to position functionality on larger molecules accessing new chemical space between small molecules, such as VAST compounds, and biologics, such as antibodies. Other competitors include companies with an interest in cancer stem cells, mentioned above, and other HA-based companies.

-31-

even more resources being concentrated among a smaller number of our competitors. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Smaller or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. It is possible that competitors may develop new products in our target market before we are able to develop such products.

It is also possible that our competitors may establish licensing agreements with large pharmaceutical and biotechnology companies in our target markets before we are able to establish such licensing arrangements or we may be unable to establish such licensing arrangements at all. Furthermore, it is possible that one or more of the competing products will achieve FDA approval before HA-Irinotecan for the treatment of mCRC or any of our other product candidates, which may limit our ability to successfully commercialize HA-Irinotecan for the treatment of mCRC, if approved, or any of our other product candidates which may have received regulatory approval. In certain instances, drugs that will compete with our product candidates are widely available or have established, existing standards of care, or may be subject to new standards of care. In particular, all of our current product candidates are combinations of HA and existing cancer drugs and therefore will compete with those existing cancer drugs used alone and combinations of those existing drugs used in existing treatment regimens and would compete with combinations of existing drugs used with future standards of care.

Competition may increase further as a result of advances in the commercial applicability of technologies currently being developed and a greater availability of capital investment in those fields. Some of the companies developing products which may compete with HA-Irinotecan for the treatment of mCRC include Sanofi/Regeneron, Bayer-Schering, AstraZeneca and Bristol-Myers Squibb. These companies also have significantly greater research and marketing capabilities than we do. In addition, many universities and U.S. private and public research institutes are active in cancer research, the results of which may result in direct competition with HA-Irinotecan for the treatment of mCRC or other of our product candidates. These companies and institutions may seek intellectual property protection with respect to potentially competitive products or technologies. These organizations may also establish exclusive collaborative or licensing relationships with our competitors. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis drug products that are more effective or less costly than any drug candidate that we are currently developing or that we may develop.

In certain instances, the drugs which will compete with our product candidates are widely available or have established, existing standards of care or may be subject to new standards of care. In particular, all of our product candidates are combinations of HA and existing cancer drugs and therefore will likely compete with those existing cancer drugs used alone and combinations of existing drugs used in existing treatment regimens and would compete with combinations of existing drugs used with future standards of care. To compete effectively with these drugs, our product candidates will need to demonstrate advantages that lead to improved clinical safety or efficacy compared with these competitive products, particularly as we expect that our products candidates, if approved, will cost more than the cancer drugs alone. We cannot assure you that we will be able to achieve competitive advantages versus alternative drugs or treatment regimens. If our competitors market products that are more effective, safer or less expensive than our product candidates, or that reach the market sooner than our product candidates, if approved, we may not achieve commercial success.

We believe that our ability to successfully compete will depend on, among other things:

•

our ability to design and successfully execute appropriate clinical trials;

•

our ability to recruit and enroll patients for our clinical trials;

•

the results of our clinical trials and the efficacy and safety of our product candidates;

•

the speed at which we develop our product candidates;

-32-

•

achieving and maintaining compliance with regulatory requirements applicable to our business;

•

the timing and scope of regulatory approvals, including labeling;

•

adequate levels of reimbursement under private and governmental health insurance plans, including Medicare;

•

our ability to protect intellectual property rights related to our product candidates;

•

our ability to commercialize and market any of our product candidates that may receive regulatory approval;

•

our ability to have our partners manufacture and sell commercial quantities of any approved product candidates to the market;

•

acceptance of our product candidates by physicians, other healthcare providers and patients; and

•

the cost of treatment in relation to alternative treatment regimens.

In addition, the biopharmaceutical industry is characterized by rapid technological change. Our future will depend in large part on our ability to maintain a competitive position with respect to these technologies. Our competitors may render our technologies obsolete by advances in existing technological approaches or the development of new or different approaches, potentially eliminating the advantages in our drug discovery process that we believe we derive from our research approach and proprietary technologies. Also, as our research approach integrates many technologies, it may be difficult for us to stay abreast of the rapid changes in each technology. If we fail to stay at the forefront of technological change, we may be unable to compete effectively.

We will not have the right to sub-license the VAST small molecule drug discovery technology without Alchemia Limited’s consent, which may prevent us from commercializing that technology.

Under the agreement pursuant to which we will in-license the VAST small molecule drug discovery technology from Alchemia Limited, we will be prohibited from sub-licensing any of that technology without the prior written consent of Alchemia Limited, which may not be unreasonably withheld. Accordingly, we will not be able to sub-license this technology to third parties or enter into collaborations with third parties pursuant to which we give them rights to the technology without Alchemia Limited’s consent. To the extent that Alchemia Limited does not give this consent, it will prevent us from realizing revenues from that technology through sub-licenses and may prevent us from commercializing that technology through other arrangements.

If we fail to attract and retain key management and scientific personnel, we may be unable to successfully develop or commercialize our product candidates.

Companies in our industry have experienced a high rate of turnover of management personnel in recent years. We will need to expand and effectively manage our managerial, operational, financial, development and other resources in order to successfully pursue our research, development and commercialization efforts for our product candidates. Because of the specialized nature of our business, we are highly dependent on qualified, scientific, technical and managerial personnel. Our success depends on our continued ability to attract, retain and motivate highly qualified personnel. There is significant competition for qualified personnel in our business. The loss of the services of any of our senior management, including Peter Smith, our President and Chief Executive Officer, Charles Walker, our Chief Financial Officer, and Tracey Brown, our Chief Science Officer, could delay

-33-

or prevent the commercialization of our product candidates. We will maintain “key man” insurance policies on the lives of these officers; however, we generally do not expect the proceeds from any of these policies to adequately compensate us for the loss of any these individuals. We employ these individuals on an at-will basis and their employment can be terminated by us or them at any time, for any reason. In order to induce valuable employees to continue their employment with us, we will provide stock options that vest over time. The value to employees of stock options that vest over time is significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract more lucrative offers from other companies. We will need to hire additional personnel as we continue to expand our research and development activities and if we ultimately proceed with building a sales and marketing function.

We have scientific and clinical advisors who assist us in formulating our research, development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

We may not be able to attract or retain qualified management, technical and scientific personnel in the future due to the intense competition for a limited number of qualified personnel among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will impede the achievement of our research and development objectives, our ability to raise additional capital and our ability to implement our business strategy. In particular, if we lose any members of our senior management team, we may not be able to find suitable replacements in a timely fashion, or at all, and our business may be harmed as a result. The loss of the services of existing personnel, as well as the failure to recruit and retain additional key scientific, technical, managerial and other personnel in a timely manner could harm our research and development programs and our business.

If our product candidates receive regulatory approval and we begin efforts to commercialize those products, we may encounter difficulties in managing our growth and expanding our operations successfully.

As we pursue our drug discovery projects and advance our product candidates through clinical trials, we will need to expand our development, regulatory, manufacturing, marketing and sales capabilities or contract with third parties to provide these capabilities for us. To the extent that our operations expand, we expect that we will need to manage additional relationships with such third parties, as well as additional collaborators and suppliers. Maintaining these relationships and managing our future growth will impose significant added responsibilities on members of our management and other personnel. We must be able to: manage our development efforts effectively; manage our clinical trials effectively; hire, train and integrate additional management, development, administrative and, if our products receive regulatory approval, sales and marketing personnel; improve our managerial, development, operational and finance systems; and expand our facilities, all of which may impose a strain on our administrative and operational infrastructure.

We currently have no marketing, sales or distribution capabilities. If our product candidates receive regulatory approval, we intend to pursue relationships with pharmaceutical companies and other strategic partners to assist us in the commercialization and distribution of our product candidates. We expect that we will initially rely upon these third parties to provide marketing, sales and distribution capabilities for any of our product candidates that receive regulatory approval. In addition, to the extent we are successful in obtaining regulatory approval for our product candidates, we may over the longer term elect to establish an internal sales and marketing organization to supplement these sales and marketing arrangements with third parties. Establishing an internal sales and marketing organization is expensive and time consuming and ultimately may not prove to be successful. Any failure or delay in the development of sales, marketing and distribution capabilities, whether through collaborations with third parties or otherwise, would adversely impact the

-34-

commercialization of any product candidates that receive regulatory approval. To the extent that we enter into agreements with third parties providing for them to market and distribute our products, any revenue we generate from sales of those products is likely to be lower than if we directly marketed or sold those product, and any revenue we receive will depend in whole or in part upon the efforts of such third parties, which may not be successful and are generally not within our control. Moreover, if we are not successful in developing sales and marketing arrangements with third parties on acceptable terms or, should we choose to do so over the longer term, developing our own sales and marketing organization, we may not be able to commercialize any of our product candidates that receive regulatory approval. Any failure to successfully commercialize our product candidates would have a material adverse effect on our business.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDA or other regulations, provide accurate information to the FDA or other regulatory authorities, comply with manufacturing standards we have established, comply with federal, state and foreign health-care fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing, promotion, sales commission, customer incentive and other business arrangements and programs. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We will adopt a Code of Business Ethics in connection with this offering, but there can be no assurance that we will be able to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective. Employee misconduct may result in governmental investigations or other actions or lawsuits that may result in substantial liabilities or other sanctions and substantial diversion of our management’s attention. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a material adverse impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Our commercial success depends upon attaining significant market acceptance of our product candidates, if approved, among physicians, patients, healthcare payors and major operators of cancer clinics.

Even if we obtain regulatory approval for our product candidates, the product candidate may not gain market acceptance among physicians, health care payors, patients and the medical community, which are critical to commercial success. Market acceptance of any product candidate for which we receive approval depends on a number of factors, including:

•

the efficacy and safety as demonstrated in clinical trials;

•

the timing of market introduction of such product candidate as well as competitive products;

•

the clinical indications for which the drug is approved;

•

acceptance by physicians, major operators of cancer clinics and patients of the drug as a safe and effective treatment;

•

the potential and perceived advantages of such product candidate over alternative treatments;

•

the cost of treatment in relation to alternative treatments;

-35-

•

the availability of adequate reimbursement and pricing by third-party payors and government authorities;

•

relative convenience and ease of administration;

•

the prevalence and severity of adverse side effects; and

•

the effectiveness of our sales and marketing efforts.

If our product candidates are approved but fail to achieve an adequate level of acceptance by physicians, health care payors and patients, we will not be able to generate significant revenues, and we may not become or remain profitable.

We rely on third parties to conduct clinical trials for our product candidates and research and development on the VAST small molecule drug discovery projects, and we plan to rely on third parties to conduct future clinical trials, research and development. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for or commercialize our product candidates.

We do not have the ability to independently conduct Phase II or Phase III clinical trials for any of our product candidates. We rely on third parties, such as contract research organizations, medical institutions, clinical investigators and contract laboratories, to conduct all of our clinical, nonclinical and preclinical studies of our product candidates; however, we remain responsible to regulatory authorities and other parties for ensuring that each of our clinical trials is conducted in accordance with its investigational plan and protocol and legal requirements. Moreover, the FDA and other non-U.S. regulatory authorities require us to comply with regulations and standards, commonly referred to as GCPs, for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate and that the trial subjects are adequately informed of the potential risks of participating in clinical trials. Our reliance on third parties does not relieve us of these responsibilities and requirements. If the third parties conducting our clinical trials do not perform their contractual duties or obligations, do not meet expected deadlines or need to be replaced, or if the quality or accuracy of the clinical data they obtain is compromised due to lack of compliance with GCPs or our clinical protocols, regulatory requirements or for any other reason, we may need to enter into new arrangements with alternative third parties and our clinical trials may be extended, delayed or terminated and the cost of those clinical trials may increase substantially, and such lack of compliance with GCPs or protocols may render any such clinical data potentially worthless to us and jeopardize the integrity and viability of the affected clinical trials. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

If any of our relationships with these third-party contract research organizations terminate, we may not be able to enter into arrangements with alternative contract research organizations or to do so on commercially reasonable terms. In addition, our contract research organizations are not our employees, and except for remedies available to us under our agreements with such organizations, we cannot control whether or not they devote sufficient time and resources to our on-going clinical, nonclinical and preclinical programs.

Switching or adding additional contract research organizations involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new contract research organization commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines and can increase our costs significantly. Though we seek to manage our relationships with our contract research organizations, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

-36-

We plan to undertake drug discovery projects internally and through collaborations with research institutes and pharmaceutical and biotechnology companies. We cannot guarantee that our strategic partners or collaborators involved in VAST small molecule drug discovery projects will deliver the results necessary for commercialization. Strategic partners and collaborators undertaking research may not perform their contractual duties or obligations, may not meet expected deadlines or may need to be replaced. We may need to renegotiate agreements or find alternative partners, which may extend, delay or terminate projects, potentially increasing costs.

If a successful clinical trial or product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, we could be forced to pay substantial damage awards.

The use of any of our product candidates in clinical trials, and the sale of any approved product candidates, may expose us to clinical trial and product liability claims. We currently maintain clinical trial insurance coverage in an amount of up to $20 million per occurrence, or up to $20 million in the aggregate, and do not currently maintain product liability insurance. However, we cannot assure you that such insurance coverage will protect us against some or all of the claims to which we might become subject. Moreover, in the future, we might not be able to maintain adequate insurance coverage at a reasonable cost or in sufficient amounts or scope to protect us against potential losses. In the event a claim is brought against us and our insurance is either inadequate to cover or does not cover that claim or we do not have insurance at all, we would be required to pay legal and other expenses to defend the claim, as well as uncovered damages awards resulting from a claim brought successfully against us or any uncovered amounts that we may be required to pay to settle such claim. Furthermore, whether or not we are ultimately successful in defending any such claims, we might be required to direct substantial financial and managerial resources to such defense and adverse publicity could result, all of which could materially harm our business.

If we violate the rules and regulations governing our business, including regulations pertaining to promotion and advertising of our clinical candidates or any approved product candidates, we may be subject to disciplinary action by the FDA’s Office of Prescription Drug Promotion or other regulatory authorities.

Our business is subject to significant regulation both in the United States and internationally. The FDA’s Office of Prescription Drug Promotion, or OPDP, is responsible for reviewing prescription drug advertising and promotional labeling to ensure that the information contained in these materials is not false or misleading. There are specific disclosure requirements and the applicable regulations mandate that advertisements cannot be false or misleading or omit material facts about the product. Prescription drug promotional materials must present a fair balance between the drug’s effectiveness and the risks associated with its use. Most warning letters from OPDP cite inadequate disclosure of risk information or promotion of off-label use.

OPDP prioritizes its actions based on the degree of risk to the public health, and often focuses on newly introduced drugs and those associated with significant health risks. There are two types of letters that OPDP typically sends to companies that violate its drug advertising and promotional guidelines: notice of violation letters, or untitled letters, and warning letters. In the case of an untitled letter, OPDP typically alerts the company of the violation and issues a directive to refrain from future violations, but does not typically demand other corrective action. A warning letter is typically issued in cases that are more serious or where the company is a repeat offender. We may violate OPDP’s guidelines in the future and be subject to an OPDP untitled letter or warning letter, which may require restrictions on our ability to market our product candidates, if approved or even require full market withdrawal, either of which will have a negative impact on our business. We may also in the future violate similar laws and regulations of non-U.S. governmental authorities, which may also have a negative impact on our business.

-37-

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

If we obtain FDA approval for any of our product candidates and begin commercializing those product candidates in the United States, our operations will be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act. These laws will impact, among other things, our proposed sales, marketing and education programs. In addition, we will be subject to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce, or in return for, the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs;

•

federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent;

•

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters;

•

HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and its implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information; and

•

state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

To the extent that our product candidates receive regulatory approvals from countries outside of the United States, we may also be subject to similar laws and regulations in those countries.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from having our products reimbursed by federal healthcare programs and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

We deal with hazardous materials and must comply with environmental laws and regulations, which can be expensive and restrict how we do business.

Our activities involve the controlled storage, use, and disposal of hazardous materials, including corrosive, explosive and flammable chemicals, biologic waste and various radioactive compounds. We are subject to federal, state, and local laws and regulations governing the use, manufacture, storage, handling, and disposal of these hazardous materials. Although we believe that our safety procedures for the handling and disposing of these materials comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of contamination or injury from these materials.

-38-

In the event of an accident, state or federal authorities may curtail our use of these materials, and we could be liable for any civil damages, which may exceed our financial resources and may seriously harm our business. Additionally, an accident could damage, or force us to temporarily shut down, our operations. In addition, if we develop a manufacturing capacity, we may incur substantial costs to comply with environmental regulations and would be subject to the risk of accidental contamination or injury from the use of hazardous materials in our manufacturing process.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems and those of our contract research organizations and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of our product candidates could be delayed.

Changes in foreign currency exchange rates could materially adversely affect our business, results of operations or financial condition.

In our operations, there are transactions and balances denominated in currencies other than the U.S. dollar (which is the currency used to report our results of operations and financial condition in our financial statements), consisting primarily of the Australian dollar. Our functional currency for accounting purposes is the Australian dollar. We recorded net losses from foreign currency translation of approximately $0.1 million, $3.0 million and $2.2 million for the fiscal years ended June 30, 2010 and 2011 and the nine months ended March 31, 2011, respectively, and recorded a net gain from foreign currency translation of approximately $0.4 million for the nine months ended March 31, 2012. To the extent our assets and liabilities denominated in Australian dollars as of March 31, 2012 are not hedged, we estimate that a 10% change in the exchange rate versus the U.S. dollar would expose us to foreign currency gains or losses of approximately U.S. $2.2 million for the Australian dollar.

In addition, all of our facilities (except for a small amount of executive office space in the United States) are located in Australia, all of our officers and employees have their permanent residences in Australia and substantially all of our expenses (except for costs of clinical trials, which are typically payable into U.S. dollars) are payable in Australian dollars. In the event that the U.S. dollar weakens compared with the Australian dollar, our results of operations or financial condition may be adversely affected, perhaps substantially.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive management and qualified board members, particularly after we are no longer an “emerging growth company.”

As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq Stock Market and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources, particularly after we are no longer an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, as described in the second succeeding risk factor.

-39-

The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to remediate an existing material weakness in our internal control over financial reporting, and to maintain and improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight will be required. As a result, management’s attention may be diverted from other business concerns and these efforts will require us to hire additional personnel and incur significant expenses, which could adversely affect our business and operating results. None of our current employees has the requisite knowledge with regard to U.S. GAAP accounting or U.S. public company reporting requirements. We plan to hire a controller and an outside firm proficient in these areas to help us comply with these requirements and we may need to hire more employees in the future or engage additional outside experts, which will increase our costs and expenses. In addition, Section 404 of the Sarbanes-Oxley Act requires that our independent public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting at such time as we have ceased to be an “emerging growth company” as defined in the JOBS Act, which will result in substantial additional expense. Although the JOBS Act discussed in the second succeeding risk factor may for a limited period of time somewhat lessen the cost of complying with some of these additional regulatory and other requirements, we nonetheless expect a substantial increase in legal, accounting, insurance and certain other expenses in the future, which will adversely impact our results of operations and financial condition.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing authorities. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from other activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing authorities due to ambiguities related to practice, regulatory authorities may initiate legal or administrative proceedings against us and our business may be adversely affected.

We also expect that being a public company, together with these new rules and regulations, will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

As a result of disclosure of information in this prospectus and in filings required of a public company, our business and financial condition will become more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and operating results could be adversely affected, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adversely affect our business and operating results.

Our independent public accounting firm identified a material weakness in our internal control over financial reporting. If we fail to remediate this material weakness or are unable to achieve and maintain effective internal control over financial reporting in the future, the accuracy and timeliness of our financial reporting may be adversely affected.

Effective internal controls are necessary for us to provide reliable financial reports. Our independent public accounting firm has identified a material weakness in our internal control over financial reporting. A material

-40-

weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected in a timely basis. The material weakness relates to our lack of sufficient accounting personnel with an appropriate level of knowledge, experience and training in U.S. GAAP accounting and U.S. public company reporting requirements to properly identify, analyze and conclude on accounting issues and to prepare financial statements in accordance with U.S. GAAP and U.S. public company reporting requirements. Our independent public accountants also noted that we lack the formal policies and procedures to ensure that U.S. GAAP accounting practices are appropriate and consistently applied. Examples of this material weakness included the following: for our 2006 acquisition of Meditech Research Ltd (currently known as Alchemia Oncology Pty Limited), management was unable to identify that, under U.S. GAAP, the transaction was to be accounted for as an asset acquisition, and in addition, management failed to properly consider that, under U.S. GAAP, the patents acquired should be classified as in-process research and development (which is required to be written off immediately if there is no alternative future use). Further, our management failed to properly consider other intangibles that are potentially acquired in an acquisition in its U.S. GAAP analysis of the acquisition. Likewise, our independent public accountant noted that disclosure adjustments were required in connection with our future commitments under research and development agreements. All of our financial reporting is carried out by our Chief Financial Officer and a limited number of other employees, all of whom lack expertise in U.S. GAAP accounting and public company reporting requirements.

We have not yet been able to remediate this material weakness. However, we plan to take steps intended to address the underlying causes of the material weakness in the immediate future, primarily through the hiring of a third party firm proficient in U.S. GAAP to review our financial statements and a controller with knowledge, experience and training in U.S. GAAP accounting and U.S. public company reporting, as well as the development and implementation of formal policies and improved processes and procedures, and by having our Chief Financial Officer and our other employees responsible for the preparation of the financial statements attend U.S. GAAP accounting and public company reporting training. We do not know the specific timeframe needed to remediate the internal control deficiency underlying this material weakness. In addition, we expect to incur significant costs associated with this remediation, primarily due to the hiring of this controller, the retention of this third-party firm, and the enhancement of our accounting and financial reporting systems. If we fail to enhance our internal controls to remediate this material weakness or to meet the demands that will be placed upon us as a public company, including the requirements of the Sarbanes-Oxley Act, we may be unable to accurately report our financial results, or report them within the timeframes required by law or stock exchange regulations. Failure to comply with Section 404 of the Sarbanes-Oxley Act could also potentially subject us to sanctions or investigations by the SEC or other regulatory authorities. We cannot assure you that we will be able to remediate this material weakness in a timely manner, or at all, or that in the future additional material weaknesses or significant deficiencies will not exist or otherwise be discovered, a risk that is significantly increased in light of our multi-national operations. If our efforts to remediate the material weakness identified are not successful, or if other material weaknesses or other deficiencies occur, our ability to accurately and timely report our financial position could be impaired, which could result in late filings of our annual and quarterly reports under the Exchange Act, restatements of our consolidated financial statements, or a decline in our stock price, suspension or delisting of our common stock from the Nasdaq Global Market, or adversely affect our reputation, results of operations and financial condition.

The JOBS Act allows us to postpone the date by which we must comply with certain laws and regulations intended to protect investors and to reduce the amount of information we have provided to you in this prospectus and will provide in our reports filed with the SEC subsequent to this offering, which may have an adverse effect on the trading price of our common stock.

The JOBS Act is intended to reduce the regulatory burden on “emerging growth companies.” As defined in the JOBS Act, a public company whose initial public offering of common equity securities occurred after

-41-

December 8, 2011 and whose annual gross revenues are less than $1.0 billion will, in general, qualify as an “emerging growth company” until the earliest of:

•

the last day of its fiscal year following the fifth anniversary of the date of its initial public offering of common equity securities;

•

the last day of its fiscal year in which it has annual gross revenue of $1.0 billion or more;

•

the date on which it has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; and

•

the date on which it is deemed to be a “large accelerated filer,” which will occur at such time as the company (a) has an aggregate worldwide market value of common equity securities held by non-affiliates of $700 million or more as of the last business day of its most recently completed second fiscal quarter, (b) has been required to file annual and quarterly reports under the Exchange Act for a period of at least 12 months, and (c) has filed at least one annual report pursuant to the Exchange Act.

Under this definition, we will be an “emerging growth company” upon completion of this offering and could remain an emerging growth company until as late as June 30, 2018.

We have chosen to take advantage of certain provisions of the JOBS Act that allow us to reduce the amount of information we have provided to you in this prospectus. As a result, this prospectus includes less information about us than would otherwise be required if we were not an “emerging growth company,” which may make it more difficult for you to evaluate an investment in our company. Likewise, although we are still evaluating the JOBS Act, we currently intend to take advantage of some or all of the reduced regulatory and reporting requirements applicable to reports and proxy statements that we file with the SEC in the future, which will be available to us so long as we qualify as an “emerging growth company,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Among other things, this means that our independent registered public accounting firm will not be required to provide an attestation report on the effectiveness of our internal control over financial reporting so long as we qualify as an emerging growth company, which may increase the risk that material weaknesses or other deficiencies in our internal control over financial reporting go undetected. So long as we qualify as an “emerging growth company,” we may elect not to provide you with certain information, including certain financial information and certain information regarding compensation of our executive officers, that we would otherwise have been required to provide in filings we make with the SEC, which may make it more difficult for investors and securities analysts to evaluate our company. As a result, investor confidence in our company and the market price of our common stock may be adversely affected.

We may be unsuccessful in managing our international operations which could adversely affect our ability to grow.

As noted above, all of our facilities (except for a small amount of executive office space) and employees are located in Australia and, in the future, we may add employees and facilities in Australia or other foreign countries. Operating in international markets requires significant resources and management attention and subjects us to regulatory, economic and political risks and competition that are different from those in the United States. We cannot assure you that we will be successful in managing our international operations.

-42-

Our international operations may not succeed due to other risks inherent in operating businesses internationally, including:

•

our lack of familiarity with commercial and social norms and customs in international countries, which may harm our ability to operate in these countries;

•

difficulties and costs associated with managing foreign operations;

•

the potential diversion of management’s attention to oversee and direct operations that are geographically distant;

•

compliance with multiple, conflicting and changing governmental laws and regulations;

•

legal systems in which our ability to enforce and protect our rights may be different or less effective than in the United States and in which the ultimate result of dispute resolution is more difficult to predict;

•

laws and business practices favoring local competitors and new and different sources of competition;

•

more limited protection for intellectual property rights in some countries;

•

fluctuations in currency exchange rates; and

•

restrictions on the transfer of funds.

Our failure to manage any of these risks successfully could harm our existing and future international operations and impair our overall business.

We may be adversely affected by seismic activity or other natural disasters, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our executive offices are located in the San Francisco Bay Area and our research and development facilities are located in Australia. The San Francisco Bay Area is known to experience earthquakes from time to time, some of which have been severe. In addition, severe weather systems frequently affect Australia. Earthquakes in the San Francisco Bay Area or Asia Pacific region may also result in tsunamis. We do not carry earthquake insurance. If a disaster, power outage or other event occurred that prevented us from using all or a significant portion of our facilities, that damaged critical infrastructure, or that otherwise disrupted our operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity planning that we have done is limited and is unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans which, particularly when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

Our ability to use net operating losses to offset future taxable income may be subject to certain limitations.

We have historically been subject to taxation in Australia and not the United States. As of March 31, 2012, we had net operating loss carryforwards, or NOLs, for Australian tax purposes of $68.0 million that are available to offset any future taxable income we may generate in Australia and which can be carried forward indefinitely. A lack of future taxable income in Australia would adversely affect our ability to utilize these NOLs. In addition, these NOLs may be adjusted if we are unable to comply with the recognition criteria for NOLs under Australian laws. Future events such as capital injections and changes in our business or capital structure require evaluation as to the impact on continued availability of historical tax losses to offset future taxable income, if any, in

-43-

Australia. Pursuant to Australian tax law, NOLs may not be available and would thus be derecognized (i.e. lost) where there has been a greater than 50 percent change in the cumulative ownership of our company combined with a change in our business or capital structure. Accordingly, certain years’ tax losses may fail the continuity of ownership test, or COT, and later year tax losses may pass. If a company does not satisfy the COT in respect of a particular loss year, it must instead satisfy the same business test, or SBT, to be eligible to utilize prior year losses. The SBT broadly requires the company to carry on the same business for the entire year in which it seeks to recoup losses as it did when it failed COT. Future changes in our stock ownership, many of the causes of which are outside of our control, could result in an ownership change. As a result of these limitations, we may not be able to utilize any or a material portion of the NOLs. In addition, these NOLs would not be available to offset taxable income, if any, that we may generate in tax jurisdictions outside of Australia.

Risks Related to Intellectual Property

Our proprietary rights may not adequately protect our technologies and product candidates.

Our commercial success will depend in part on our ability to obtain additional patents and protect our existing patent position as well as our ability to maintain adequate protection of other intellectual property for our technologies, product candidates, and any future product candidates in the United States and other countries. We pursue a policy of seeking to obtain patent protection for our inventions in Australia, the U.S., Europe, Japan and other selected countries. We also rely on trade secrets, know-how, continuing technology innovations and licensing opportunities to develop and maintain our competitive position. If we do not adequately protect our intellectual property, competitors may be able to use our technologies and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability. The laws of some foreign countries do not protect our proprietary rights to the same extent or in the same manner as U.S. laws, and we may encounter significant problems in protecting and defending our proprietary rights in these countries. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. In addition, protecting patents and other intellectual property from alleged infringement may require expensive and time-consuming legal proceedings, and our ability to defend our intellectual property will therefore also depend upon the sufficiency of our cash resources.

We maintain an active practice of filing patent applications, and we apply for patents covering our technologies if we believe that the cost of obtaining patent protection for the technology is justified by its commercial potential, but typically seek patent protection only in those countries that we believe present significant commercial opportunities. However, we may fail to apply for patents on important technologies in a timely fashion, or at all. Our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products and technologies. Likewise, obtaining patent protection in any specific country may be expensive and time-consuming and we have elected, and in the future likely will elect, not to pursue patent protection in certain countries, meaning that we will not be able to prevent third parties from using our technologies in those countries. We cannot be certain that our patent applications, or the applications of parties that have licensed their inventions to us, will be approved or that any patents owned by or licensed to us will adequately protect our intellectual property or product candidates. Issued patents may not provide significant proprietary protection or commercial advantage or may be infringed or designed around by others. In addition, we generally do not have the right to control the defense of patents and other intellectual property that we license from others. Accordingly, we are unable to exercise the same degree of control over this intellectual property as we would over our own and would need to involve the third party licensors in legal proceedings or obtain their permission, which may not be granted, to enforce these intellectual property rights on their behalf. Moreover, the patent positions of biopharmaceutical companies are often highly uncertain and involve complex legal and factual questions for which important legal principles are often evolving and remain unresolved. As a result, the validity and enforceability of patents cannot be predicted with certainty. In addition, we do not know whether:

•

we or our licensors were the first to make the inventions covered by each of the issued patents and patent applications that we own or that are licensed to us;

-44-

•

we or our licensors were the first to file patent applications for these inventions;

•

any of our product candidates will be eligible for listing in the publication Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, a resource that identifies drug products approved by the FDA on the basis of safety and effectiveness;

•

others will independently develop similar or alternative technologies or duplicate any of our technologies;

•

any of our or our licensors’ pending patent applications will result in issued patents;

•

any of our or our licensors’ patents will be valid or enforceable;

•

any patents issued to us or our licensors and collaboration partners will provide us with any competitive advantages, or will be challenged by third parties;

•

we will develop additional proprietary technologies that are patentable;

•

the U.S. government will exercise any of its statutory rights to our intellectual property that was developed with government funding; or

•

our business may infringe the patents or other proprietary rights of others.

The actual protection afforded by a patent varies based on products or processes, from country to country and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory related extensions, the availability of legal remedies in a particular country, the validity and enforceability of the patents and our financial ability to enforce our patents and other intellectual property. Our ability to maintain and solidify our proprietary position for our technology will depend on our success in obtaining effective claims and enforcing those claims once granted. Our issued patents and those that may be issued in the future, or those licensed to us, may be challenged, narrowed, invalidated or circumvented, and the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages against competitors with similar products or technologies. Due to the extensive amount of time required for the development, testing and regulatory review of a potential product, it is possible that, before any of our product candidates can be commercialized, any patent on the technology relevant to that product candidate may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of the patent.

We also rely on trade secrets to protect some of our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to maintain. While we use reasonable efforts to protect our trade secrets, our or any of our collaboration partners’ employees, consultants, contractors or scientific and other advisors may unintentionally or willfully disclose our proprietary information to competitors and we may not have adequate remedies in respect of that disclosure. Enforcement of claims that a third party has illegally obtained and is using trade secrets is expensive, time consuming and uncertain. In addition, non-U.S. courts are sometimes less willing than U.S. courts to protect trade secrets. If our competitors independently develop equivalent knowledge, methods and know-how, we would not be able to assert our trade secrets against them and our business could be harmed. No assurance can be given that others will not independently develop substantially equivalent proprietary technology and techniques, or otherwise gain access to our proprietary technology or disclose such technology, or that we can meaningfully protect our rights to our unpatented proprietary technology, trade secrets and know-how.

The protection for any intellectual property we may in-license in the future may be dependent on third parties.

We may in the future in-license certain patents and other intellectual property relevant to our product candidates. The right and/or obligation to prosecute and maintain patents, patent applications and other

-45-

intellectual property that we may in-license in the future may be retained by the applicable licensor and, in those cases, we will not have the right to prosecute and maintain such patents, patent applications or other intellectual property without the consent of the applicable licensor or in other limited circumstances specified by the applicable license agreement. If any licensor fails to appropriately prosecute and maintain patent protection for any of the patents, patent applications or other intellectual property that they have licensed to us, our ability to develop and commercialize our product candidates may be adversely affected and we may not be able to prevent competitors from making, using and selling competing products.

If we breach any of the agreements under which we license rights to patents or other intellectual property from third parties, we could lose license rights that are important to our business.

We will in-license the rights to the technology for the VAST small molecule drug discovery technology from Alchemia Limited through our Australian subsidiary, Audeo Discovery Pty Limited, and we may in the future in-license patents or other intellectual property relevant to our product candidates. Under the license agreement with Alchemia Limited, we will be subject to development obligations, reporting obligations, sublicense revenue sharing requirements, royalty payments and other obligations and in the future we may be subject to similar obligations with respect to any patents or other intellectual property we in-license. If we fail to comply with any of our obligations under, or otherwise breach our license agreement with Alchemia Limited or any other future in-licenses, the applicable licensor may have the right to terminate the license in whole or in part or, in some cases, to terminate the exclusive nature of the license. Generally, the loss of any current or future licenses or the exclusivity rights provided therein could materially harm our financial condition and operating results.

The patent protection for the technologies relevant to our product candidates and the VAST small molecule drug discovery technology may expire before we are able to maximize their commercial value, which may subject us to increased competition and reduce or eliminate our opportunity to generate product revenue.

The patents for the technologies relevant to our product candidates and the VAST small molecule drug discovery technology have varying expiration dates and, if these patents expire, we may be subject to increased competition and we may not be able to recover our development costs or market any of our approved product candidates profitably. In some of the larger potential markets, such as the United States and Europe, patent term extension or restoration may be available to compensate for time taken during aspects of the product’s development and regulatory review. However, we cannot be certain that such an extension will be granted, or if granted, what the applicable time period or the scope of patent protection afforded during any extension period will be. In addition, even though some regulatory authorities may provide some other exclusivity for a product under their own laws and regulations, we may not be able to qualify any of our product candidates for this treatment. If we are unable to obtain patent term extension/restoration or some other exclusivity, we could be subject to increased competition and our opportunity to establish or maintain product revenue could be substantially reduced or eliminated. Furthermore, we may not have sufficient time to recover our development costs prior to the expiration of our owned and in-licensed U.S. and non-U.S. patents.

We are aware of two patents that could potentially impede our ability to commercialize HA-Irinotecan for the treatment of mCRC and our HA-5-fluorouracil product candidate and we may need to in-license those patents in order to commercialize those product candidates.

We are aware of two patents, both held by Pfizer, that could potentially impede our ability to commercialize HA-Irinotecan for the treatment of mCRC if it receives regulatory approval. These patents could also potentially impede our ability to commercialize certain of our other product candidates that may receive regulatory approval. We may need to in-license these two patents, both of which cover methods of treating cancer, including mCRC, involving administration of compounds used in the FOLFIRI chemotherapy regimen. There can be no assurance

-46-

that we will be successful in in-licensing these patents or, if we are successful in doing so, as to the amount of royalties we will be required to pay. If we fail to in-license these patents, it may limit our commercialization of our lead product candidate, HA-Irinotecan, if approved, which will likely have a material adverse effect on our business, results of operations and financial condition. Likewise, even if we are able to in-license these patents, we may be required to pay substantial royalties, the term of the in-license may be limited and therefore require periodic renewals, the countries in which we are entitled to use the patents may be limited, and the other terms of the license may be unfavorable to us, any of which could have a material adverse effect on our business, results of operations and financial condition.

These patents also could potentially impede our ability to commercialize certain of our current product candidates (if approved), including HA-5-fluorouracil, and may impede our ability to commercialize future product candidates which we may develop and which may receive regulatory approval. Accordingly, we also may be required to in-license the rights to these two patents in order to pursue our efforts to commercialize our other product candidates and any failure to do so, or any terms of any in-license that are unfavorable to us, could also have a material adverse effect on our results of operations, financial condition and business.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on the intellectual property relevant to our product candidates throughout the world would be prohibitively expensive. Accordingly, we plan to pursue patent protection for intellectual property relevant to our product candidates only in major markets, such as the United States, Australia, the European Union and Japan and only for those technologies where we believe that the costs of obtaining patent protection are justified by their commercial potential. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection but where enforcement is not as strong as that in the United States. These products may compete with our product candidates or the VAST small molecule drug discovery technology in jurisdictions where we do not have any patent protection and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or disclosed alleged confidential information or trade secrets of their former employers.

As is commonplace in our industry, we employ individuals who were previously employed at other biopharmaceutical companies, including our competitors or potential competitors. Although we have not received any claim to date, we may be subject in the future to claims that our employees or prospective employees are subject to a continuing obligation to their former employers, such as non-competition or non-solicitation obligations, or claims that our employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management.

-47-

If we are sued for infringing intellectual property rights of third parties, litigation will be costly and time-consuming and could prevent us from developing or commercializing our product candidates.

Our commercial success depends, in part, on our not infringing the patents and proprietary rights of other parties and not breaching any collaboration or other agreements we have entered into with regard to our technologies and product candidates. Numerous third-party U.S. and non-U.S. issued patents and pending applications exist in the areas relevant to our technologies and product candidates.

As patent applications can take several years to issue, if they are issued at all, there may currently be pending applications, unknown to us, that may result in issued patents that cover our technologies or product candidates. As publication of inventions or discoveries in scientific or patent literature often lags behind actual invention or discovery, it is possible that the inventions covered by each of our pending patent applications may not have dominant status in terms of date of invention. It is uncertain whether the issuance of any third-party patent would require us to alter our product candidates or processes, obtain licenses or cease activities related to the development or commercialization of our product candidates. If we wish to use the technology or compound claimed in issued and unexpired patents owned by others, we may need to obtain a license from, and pay royalties to, the owner, enter into litigation to challenge the validity of the patents or incur the risk of litigation in the event that the owner asserts that any of our product candidates infringe its patents. The failure to obtain a license to technology or the failure to challenge an issued patent that we may require to discover, develop or commercialize our product candidates may have a material adverse impact on us.

There is a substantial amount of litigation involving intellectual property in the biopharmaceutical industry generally. If a third party asserts that our product candidates or technologies infringe its patents or other proprietary rights, we could face a number of risks that could seriously harm our results of operations, financial condition and competitive position, including:

•

infringement and other intellectual property claims, which would be costly and time-consuming to defend, whether or not the claims have merit, and which could delay the regulatory approval process for our product candidates and divert management’s attention from our business;

•

substantial damages for past infringement, which we may have to pay if a court determines that our product candidates or technologies infringe a competitor’s patent or other proprietary rights or in order to settle similar claims;

•

a court prohibiting us from selling or licensing our technologies or our product candidates unless the third-party licenses its patents or other proprietary rights to us on commercially reasonable terms, which it is not required to do;

•

if a license is available from a third party, we may have to pay substantial royalties or lump sum payments or grant cross-licenses to our patents or other proprietary rights to obtain that license; and

•

redesigning our product candidates so they do not infringe, which may not be possible or may require substantial monetary expenditure and time.

To our knowledge, as of June 15, 2012, no third party had threatened or instituted proceedings against us or against Alchemia Limited or any of its subsidiaries relating to any of the intellectual property that we own or that we will license from Alchemia Limited. Although, as of June 15, 2012, neither we nor Alchemia Limited, nor any of its subsidiaries, was a party to any legal proceedings relating to any such intellectual property, in the future, third parties may file claims asserting that our technologies or product candidates infringe on their intellectual property. We cannot predict whether third parties will assert these claims against us, against Alchemia Limited or against any other current or future licensors of technology licensed to us, or whether those claims will harm our business. If we are forced to defend against these claims, whether they are with or without

-48-

any merit and whether they are resolved in favor of or against us or our licensors, we may face costly litigation and diversion of management’s attention and resources. Moreover, in the case of infringement claims relating to intellectual property that has been licensed to us, we may not be able to control or even participate in the defense of those claims and therefore may be entirely dependent on the licensor or other owner of that intellectual property for that defense. As a result of these disputes, we may have to develop costly non-infringing technology, or enter into licensing agreements requiring us to make substantial payments to the licensors. These agreements, if necessary, may be unavailable on terms acceptable to us, or at all, which could seriously harm our business or financial condition.

One or more third-party patents or patent applications may conflict with patent applications to which we have rights. Any such conflict may substantially reduce the coverage of any rights that may issue from the patent applications to which we have rights. If third parties file patent applications in technologies that also claim technology to which we have rights, we may have to participate in interference proceedings with the U.S. Patent and Trademark Office, or USPTO, or non-U.S. patent regulatory authorities, as applicable, to determine priority of invention.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property rights, which could be expensive, time-consuming and unsuccessful.

As of June 15, 2012, neither we nor Alchemia Limited, nor any of its subsidiaries, had threatened or instituted proceedings against any third party on patent or other proprietary rights. However, competitors may infringe our patents or other intellectual property rights. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time consuming. To the extent such claims relate to patents licensed to us by Alchemia Limited or any other third party, either Alchemia Limited or the applicable licensor, as the case may be, would have to file such an infringement lawsuit since we do not have the independent right to enforce their intellectual property. In addition, in an infringement proceeding, a court may decide that a patent that we own or that is licensed to us is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of the patents that we own or in-license at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Interference or derivation proceedings brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents and patent applications or those of our current or future licensors and collaborators. Our patents and patent applications may also be the subject of other contested proceedings before the USPTO or other patent offices. An unfavorable outcome could require us to cease using the technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if a prevailing party does not offer us a license on terms that are acceptable to us. Litigation, interference or derivation proceedings or other contested proceedings may have unfavorable outcomes and, even if successful, may result in substantial costs and distraction of our management and other employees. We may not be able to prevent, alone or with our collaborators, misappropriation of our proprietary rights, particularly in countries where the laws may not protect those rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential and proprietary information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.

Risks Related to Our Demerger from Alchemia Limited

We have no operating history as a separate public company, and our historical and pro forma financial information is not necessarily representative of the results that we would have achieved as a separate, publicly traded company and may not be a reliable indicator of our future results.

Prior to the consummation of this offering and the Demerger, our business has been operated as part of the business of Alchemia Limited. As a result, our consolidated financial statements and other historical and pro forma financial information included in this prospectus are derived from the consolidated financial statements and accounting records of Alchemia Limited and our consolidated financial statements include allocations of expenses, primarily salaries and benefits (including stock-based compensation) of officers and other employees of Alchemia Limited, expenses for compensation and reimbursement paid to directors of Alchemia Limited and insurance expenses incurred by Alchemia Limited. These expenses have been allocated based on our estimated share of Alchemia Limited’s expenses. Although we believe that these allocation methodologies are reasonable, these methodologies are nonetheless subject to a number of uncertainties and assumptions. Likewise, our expenses are expected to increase substantially when we begin operating as a separate public company and there are likely to be other significant differences in our operations compared to our operations while we were part of Alchemia Limited. Accordingly, the consolidated financial statements and other historical and pro forma financial information included here do not purport to reflect the results of operations, financial position and cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future. In addition, the following factors, among others, may cause differences between our results of operations and financial condition prior to and after this offering:

•

To date, all funds necessary for our research and development, working capital and other requirements, including costs of preclinical and clinical trials, research and development, general and administrative and capital expenditures, have been provided by Alchemia Limited. Following the completion of the Demerger and this offering, we will need to obtain substantial additional external financing in order to complete clinical trials, commercialize any product candidates that may receive regulatory approval and meet other cash needs, and neither Alchemia Limited nor any other third party will have any obligation to provide us financing in the future. Accordingly, we will be wholly dependent on our ability to raise additional capital through public offerings or private placements of debt or equity securities, strategic relationships or other arrangements, and there can be no assurance that we will be able to do so on acceptable terms or at all.

•

Subsequent to the completion of the Demerger, the cost of capital for our business may be higher than Alchemia Limited’s cost of capital prior to the separation.

Other significant changes may occur in our cost structure, management, financing and business operations as a result of operating as a public company separate from Alchemia Limited. The adjustments and allocations we have made in preparing our consolidated financial statements and other historical and pro forma financial information included herein do not purport to reflect our operations during those periods as if we had in fact operated as a stand-alone entity, or what the actual effect of our Demerger from Alchemia Limited will be.

The Demerger may adversely affect our business, and we may not achieve some or all of the expected benefits of the Demerger.

We may not be able to achieve the benefits expected to result from the Demerger, or such benefits may be delayed or not occur at all. As a result of the Demerger, we anticipate benefits that may include improved strategic planning, increased management focus and streamlined decision-making for the HyACT and VAST platforms. We may not achieve these anticipated benefits for a variety of reasons and there can be no assurance that the Demerger will not adversely affect our business.

-50-

Our inability to resolve any disputes that arise between us and Alchemia Limited with respect to our past and ongoing relationships may adversely affect our business.

Disputes may arise between Alchemia Limited and us in a number of areas relating to our past and ongoing relationships, including

•

tax, indemnification and other matters arising from the Demerger;

•

pricing for and provision of transitional services; and

•

licensing arrangements relating to VAST technology.

We may not be able to resolve any potential conflicts, and even if we do, the resolution may be less favorable than if we were dealing with an unaffiliated party. The ultimate outcome of any disputes or disagreements with Alchemia Limited, if unfavorable to us, could have an adverse effect on our business, which could be material.

Certain of our officers and directors will hold positions at Alchemia Limited for a short time after the Demerger, which may cause them to have actual or potential conflicts of interest and will limit the attention they devote to our business. In addition, all of our officers and some of our employees own Alchemia Limited ordinary shares and/or options to purchase Alchemia Limited ordinary shares, which may also result in actual or potential conflicts of interest.

Certain of our officers and directors may have actual or potential conflicts of interest because of their positions with Alchemia Limited. For example, we currently expect that our Chief Executive Officer and Chief Financial Officer will each continue to serve as the chief executive officer and chief financial officer of Alchemia Limited for a number of months after the Demerger as part of the transitional services arrangement between us and Alchemia Limited. In addition, such officers own, and all of our other officers and some of our employees own, Alchemia Limited ordinary shares and/or options to purchase Alchemia Limited ordinary shares, and these holdings of Alchemia Limited ordinary shares and/or options to purchase ordinary shares of Alchemia Limited may be significant for some of these persons compared with these persons’ total assets. These positions at Alchemia Limited and the ownership of any Alchemia Limited shares or equity awards creates, or may create the appearance of, conflicts of interest when these officers, directors and employees are faced with decisions that could have different implications for Alchemia Limited than the decisions have for us. In addition, we currently expect that our Chief Executive Officer and Chief Financial Officer will, so long as they are also serving as officers of Alchemia Limited, divide their attentions between Alchemia Limited and our company, which will limit the attention they devote to our business and may adversely affect our business and prospects.

Third parties may seek to hold us responsible for liabilities of Alchemia Limited.

Until the Demerger, our business will have been operated as a part of Alchemia Limited. Accordingly, third parties may seek to hold us responsible for Alchemia Limited’s liabilities, whether incurred prior to or after the Demerger. In addition, we may be required to indemnify Alchemia Limited for those claims and any related losses pursuant to the agreement described in the next risk factor.

We will be subject to risks resulting from cross-indemnification in connection with the Demerger.

In connection with the Demerger, Alchemia Limited will agree to indemnify us for any claim or loss suffered by us where the claim or loss relates to the business of Alchemia Limited (excluding the business of Alchemia Oncology Pty Limited). (We will be responsible for any income tax payable by Alchemia Oncology Pty Limited for the period prior to and after the Demerger.) If third parties bring claims against us for liabilities

-51-

relating to Alchemia Limited’s business that would entitle us to that indemnity and if Alchemia Limited fails to indemnify us, it could have a material adverse effect on our results of operations and financial condition. Likewise, we have agreed to indemnify Alchemia Limited for any claim or loss relating to the business of our subsidiary Alchemia Oncology Pty Limited. Any requirement that we indemnify Alchemia Limited under these circumstances could also have a material adverse effect on our results of operations and financial condition.

Risks Related to Ownership of Our Common Stock and this Offering

We expect that our stock price will fluctuate significantly, you may not be able to resell your shares at or above the initial public offering price and you may lose all or part of your investment.

Prior to this offering, there has been no public market for shares of our common stock. We cannot predict the extent to which investor interest in our company will lead to the development of an active trading market for our common stock on The Nasdaq Global Market or otherwise or how liquid that market might become. If an active trading market does not develop, you may have difficulty selling any of our shares of common stock that you buy. We and the underwriters will determine the initial public offering price of our common stock through negotiation. This price will not necessarily reflect the price at which investors in the market will be willing to buy and sell our shares following this offering. In addition, the trading price of our common stock following this offering may be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, and you may lose all or part of your investment. These factors include:

•

actual or anticipated quarterly variations in our results of operations or the results of our competitors;

•

announcements by us or our competitors of new commercial products, significant contracts, commercial relationships or capital commitments;

•

issuance of new or changed securities analysts’ reports or recommendations for our stock;

•

developments or disputes concerning our intellectual property or other proprietary rights;

•

commencement of, or our involvement in, litigation;

•

market conditions in the life sciences sectors;

•

failure to complete clinical trials successfully, or at all, or to obtain regulatory approvals for our product candidates;

•

manufacturing or supply disruptions at our contract manufacturers, or failure by our contract manufacturers to obtain or maintain approval of the FDA or comparable regulatory authorities;

•

any future sales of our common stock or other securities;

•

any major change in our board of directors or management;

•

adverse results in preclinical studies or clinical trials by us or other companies;

•

general economic conditions and slow or negative growth of our markets; and

•

other events or factors, including those resulting from war, incidents of terrorism or responses to these events.

In addition, the CDIs representing shares of our common stock distributed in the Demerger will be listed and will trade on the Australian Securities Exchange and, as a result, there will be an independent trading market

-52-

for our CDIs in Australia. The CDIs are, in general, the economic equivalent of shares of our common stock and, as a result, the trading price of the CDIs on the Australian Securities Exchange will likely affect the trading price of our common stock on the Nasdaq Global Market, and vice versa. The trading price of the CDIs may be influenced by factors different from those that affect the trading price of our common stock on the Nasdaq Global Market and, as discussed below in these risk factors, may be influenced by arbitrage activities. In addition, holders of shares of our common stock, including shares sold in this offering, may deliver those shares to the depositary for the CDIs in exchange for CDIs. If a significant number of the shares of our common stock that are sold in the offering are exchanged for CDIs, it may have an adverse effect, which could be material, on the liquidity and trading price of our common stock on the Nasdaq Global Market.

The stock market in general, and market prices for the securities of technology-based companies like ours in particular, have from time to time experienced extreme volatility that often has been unrelated to the operating performance of the underlying companies. A certain degree of stock price volatility can also be attributed to being a newly public company. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In several recent situations where the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and harm our operating results.

If securities or industry analysts do not publish research or reports about our business, publish negative reports about our business or cease coverage of our company, our share price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business, our market and our competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares, change their opinion of our shares or cease coverage of our company, our share price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

We may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a return.

We currently intend to use the net proceeds we receive from this offering as follows: to complete our pivotal Phase III clinical trial and related regulatory filings for HA-Irinotecan for the treatment of mCRC; to prepare for commercial-scale manufacturing of HA-Irinotecan, if approved for the treatment of mCRC; to fund our research and drug discovery activities related to additional drug candidates; and the balance for general corporate purposes, including working capital and capital expenditures, which may include the acquisition or in-licensing of additional compounds, product candidates and technology, although we have no present commitments or agreements to enter into any such acquisitions. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. In addition, it is possible that the net proceeds we receive from this offering will not be sufficient for the purposes discussed under “Use of Proceeds.” The net proceeds may be used for purposes that do not increase the value of our business, which could cause our stock price to decline. Until these funds are used, they may be placed in investments that produce only limited income or do not produce income at all or that lose value.

-53-

Future sales of shares of our common stock could cause the market price of our common stock to decline. This risk is heightened by the fact that, in addition to the shares sold in this offering, shares of our common stock distributed in the Demerger and CDIs representing those shares will be freely tradable in the public markets immediately upon completion of this offering, and a number of the shares of our common stock distributed in the Demerger and the CDIs representing those shares will not be subject to lock-up agreements.

The market price of shares of our common stock could decline as a result of sales of our common stock or CDIs representing those shares following this offering, particularly sales by Alchemia Limited shareholders that receive CDIs or shares of our common stock in the Demerger, or the perception that these sales could occur. Immediately after this offering, we estimate that we will have approximately outstanding shares of our common stock, calculated as of the date, in the manner and subject to the assumptions set forth under “Prospectus Summary — The Offering” (as described under that caption, the actual number of shares that will be outstanding immediately after this offering will be different from the foregoing estimated number of shares.) All of the shares of our common stock outstanding immediately after this offering (which will consist of the shares sold in this offering and the shares distributed in the Demerger), as well as CDIs representing shares distributed in the Demerger, will be freely tradable in the public markets except for shares and CDIs that are held by our “affiliates” (as defined for purposes of the Securities Act of 1933), but only shares, or % of the estimated number of shares of common stock to be outstanding immediately after this offering, will be subject to lock-up agreements described under “Underwriting — Lock-Up Agreements.” This means that the remaining shares, or % of the estimated number of shares of common stock to be outstanding immediately after this offering (and, in the case of shares distributed in the Demerger, CDIs representing those shares), may be sold in the public markets immediately after this offering. Because of the number of shares of common stock and CDIs representing those shares that will be freely tradable in the public markets but will not subject to lock-up agreements, there is a substantial risk that sales of these shares or CDIs may cause the market price of our common stock to decline, perhaps significantly, and that these declines may occur immediately after our common stock and the CDIs begin to trade on the Nasdaq Global Market and the Australian Securities Exchange, respectively, or at any time thereafter.

Except for the shares sold in this offering, all of the shares of our common stock outstanding immediately after this offering will be shares distributed in the Demerger to Alchemia Limited shareholders (either in the form of CDIs representing shares of our common stock or, at their option, as shares of our common stock), all of which will be freely tradable in the public markets except for shares and CDIs that are held by our “affiliates” (as defined for purposes of the Securities Act of 1933), subject in certain cases to the lock-up agreements described under “Underwriting — Lock-up Agreements.” Although we are unable to predict whether or not shareholders of Alchemia Limited will seek to dispose of CDIs or shares of our common stock received in the Demerger, there is a risk that they may be more likely to dispose of CDIs and shares of our common stock than investors who purchase our shares in this offering and that those dispositions may begin to occur as soon as our common stock or the CDIs, as the case maybe, begin to trade on the Nasdaq Global Market and the Australian Securities Exchange, respectively.

In addition, Alchemia Limited’s stock records indicate that certain Alchemia Limited shareholders reside or are located in jurisdictions where, as a result of local securities laws, they will not be permitted to receive CDIs or shares of our common stock distributed in the Demerger (we sometimes refer to these shareholders as ineligible foreign shareholders). Accordingly, CDIs or shares of our common stock that would otherwise be distributed to these ineligible foreign shareholders will instead be delivered to a sales facilities agent, who will then sell those CDIs or shares of our common stock in the open market, which may include sales on the Australian Securities Exchange or the Nasdaq Global Market, as applicable, and remit the proceeds to the ineligible foreign shareholders. We expect that these sales will take place shortly after this offering and, as a result, these sales may result in a decline in the market price of our common stock.

In addition, concurrently with the closing of this offering we plan to grant options to purchase shares of our common stock at an exercise price equal to the initial public offering price per share set forth on the

-54-

cover page of this prospectus and to establish an equity incentive plan that will provide for the issuance of up to additional shares of our common stock, plus annual increases, beginning with our fiscal year commencing July 1, , in the number of shares available for issuance under such plan, as described under “Executive Compensation — 2012 Equity Incentive Plan.” We also intend to file a registration statement on Form S-8 to register shares of our common stock that may be issued upon exercise of these options or that we may otherwise issue under our equity incentive plan shortly after completion of this offering. Once we register these shares, they will be freely tradable in the public market upon issuance. Significant sales of our common stock pursuant to options and equity incentive plans could also harm the prevailing market price for our common stock.

As of , 2012, our officers and directors and certain Alchemia Limited shareholders who will receive CDIs or shares of our common stock in the Demerger had entered into lock-up agreements described under “Underwriting — Lock-Up Agreements” that will cover approximately % of the estimated number of shares of our common stock to be outstanding immediately after this offering. As described above under “Prospectus Summary — The Offering,” the actual number of shares of our common stock that will be outstanding after this offering will be different than the number we have assumed for purposes of computing the foregoing percentage. Leerink Swann LLC and Oppenheimer & Co. Inc. may, in their sole discretion and without notice to the public, permit our officers and directors and these shareholders to sell shares of our common stock and CDIs prior to the expiration of the lock-up agreements. Sales of our common stock or CDIs following any such waivers or upon expiration of such lock-up agreements could adversely affect the market price of our common stock.

As described under “Description of Capital Stocks — Warrants,” as required by the terms of a private placement of Alchemia Limited’s ordinary shares in 2011, following this offering we will issue Warrants to purchase shares of our common to investors that purchased ordinary shares in that placement. The Warrants will be exercisable, commencing six months after the date of this offering. Assuming that the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price over such period as the Average Trading Price) is $ per share (the midpoint of the estimated price range set forth in the cover page of this preliminary prospectus) and an exchange rate equal to U.S. dollars per Australian dollar, approximately Warrant Shares would be issuable upon exercise of the Warrants at an exercise price of approximately $ per share. Any exercise of these Warrants and sale of the shares of our common stock issued on exercise once these Warrants become exercisable could have an adverse effect on the market price of our trading stock. Please note that, because the number of Warrant Shares and the exercise price both depend upon the Average Trading Price following this offering and the number of Warrant Shares also depends on the currency exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. For information on how the number of Warrant Shares and exercise price will be calculated, and for an analysis showing how changes in the assumed initial public offering price affect the number of Warrant Shares and how changes in such currency exchange rate change the number of Warrant Shares, see “Prospectus Summary — The Offering” and “Description of Capital Stock — Warrants.”

Purchasers in this offering will experience immediate and substantial dilution in the book value of their investment.

The initial public offering price per share in this offering will be substantially higher than the pro forma as adjusted net tangible book value per share of our common stock prior to this offering. As a result, investors purchasing common stock in this offering will experience immediate dilution of $ per share in pro forma as adjusted net tangible book value per share from the initial public offering price, assuming an initial public offering price of $ per share (which is the midpoint of the estimated price range appearing on the cover page of this preliminary prospectus), calculated as described below under “Dilution.” This dilution is due in large part

-55-

to the fact that the deemed consideration we received for certain of the shares of our common stock that Alchemia Limited will distribute in the Demerger is substantially less than the initial public offering price of our common stock and the fact that we will not receive any payment for the other shares of our common stock distributed in the Demerger. Furthermore, if the underwriters exercise their option to purchase additional shares from us, you will experience, and if we issue additional equity securities, you may experience, additional dilution. In addition, as described below under “We will have outstanding options and warrants, and in the future we expect to issue additional options, that have the potential to dilute stockholder value,” we have or will have options and warrants that have the potential to dilute stockholder value further.

We will have outstanding options and warrants, and in the future we expect to issue additional options, that have the potential to dilute stockholder value.

Concurrently with the closing of this offering we plan to grant options to purchase shares of our common stock at an exercise price equal to the initial public offering price per share set forth on the cover page of this prospectus and to establish an equity incentive plan that will provide for the issuance of up to additional shares of our common stock, plus annual increases in the number of shares available for issuance under that plan, beginning with our fiscal year commencing July 1, , as described under “Executive Compensation — 2012 Equity Incentive Plan.” In the future, we expect to issue stock options or other forms of stock-based compensation to our directors, officers and employees pursuant to our equity incentive plan. In addition, as described above under “Future sales of shares of our common stock could cause the market price of our common stock to decline. This risk is heightened by the fact that, in addition to the shares sold in this offering, shares of our common stock distributed in the Demerger and CDIs representing those shares will be freely tradable in the public markets immediately upon completion of this offering, and a number of the shares of our common stock distributed in the Demerger and the CDIs representing those shares will not be subject to lock-up agreements,” following this offering we will issue Warrants to purchase shares of our common stock at an exercise price equal to 130% of the Average Trading Price of our common stock. The exercise of any of those options or warrants, and the grant or exercise of other stock-based awards we may make under our equity incentive plan, may dilute the voting, economic and other interests of holders of common stock purchased in this offering.

As a result of becoming a public company, we will be obligated to develop and maintain proper and effective internal control over financial reporting. We may not complete our analysis of our internal controls over financial reporting in a timely manner, or these internal controls may not be determined to be effective, which may adversely affect investor confidence in our company and, as a result, the value of our common stock.

We will be required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting beginning with our second filing of an Annual Report on Form 10-K with the Securities and Exchange Commission, or the SEC, after we become a public company. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on our internal control over financial reporting. Likewise, our independent registered public accounting firm will be required to provide an attestation report on the effectiveness of our internal control over financial reporting at such time as we cease to be an “emerging growth company,” as defined in the JOBS Act, although, as described in the risk factor above entitled “The JOBS Act allows us to postpone the date by which we must comply with certain laws and regulations intended to protect investors and to reduce the amount of information we have provided to you in this prospectus and will provide in our reports filed with the SEC subsequent to this offering, which may have an adverse effect on the trading price of our common stock,” we could potentially qualify as an “emerging growth company” until June 30, 2018.

We have not yet begun the costly and challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404. We may not be able to

-56-

complete our evaluation, testing and any required remediation in a timely fashion, or to remediate the existing material weakness in our internal control. During the evaluation and testing process, if we are unable to remediate the existing material weakeness in our internal control, or if we identify one or more additional material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are effective. In addition, the fact that our independent registered public accounting firm will not be required to provide an attestation report on the effectiveness of our internal control over financial reporting so long as we qualify as an “emerging growth company” may increase the risk that material weaknesses or deficiencies in our internal control over financial reporting go undetected.

If we are unable to certify that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable (at such time as it is required to do so) to express an opinion on the effectiveness of our internal controls, or if we fail to remediate material weaknesses in our internal controls, we could be subject to regulatory scrutiny and the loss of public confidence, which could harm our reputation and the market price of our common stock.

To comply with the requirements of being a public company, we will need to undertake various actions, such as implementing new internal controls and procedures and hiring accounting or internal audit staff, to a level necessary to comply with our obligations as a public company, manage our growth and to remediate the existing material weakness in our internal control, and we may discover additional material weaknesses or other deficiencies in existing systems and controls that we may not be able to remediate in an efficient or timely manner. None of our current employees has the requisite knowledge with regard to U.S. GAAP accounting or U.S. public company reporting requirements. If we do not maintain adequate financial and management personnel, processes and controls, we may not be able to manage our business effectively or accurately report our financial performance on a timely basis, which could cause a decline in our common stock price and adversely affect our results of operations and financial condition.

We are an “emerging growth company” and the reduced disclosure requirements applicable to emerging growth companies may make it more difficult for you to evaluate an investment in our company and may make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we currently intend to take advantage of some or all of the exemptions from various reporting requirements and other obligations that are applicable to public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we are choosing to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

As an “emerging growth company” we have also chosen to take advantage of certain provisions of the JOBS Act that allow us to provide you with less information in this prospectus than would otherwise be required if we

-57-

are not an “emerging growth company.” As a result, this prospectus includes less information about us than would otherwise be required if we were not an “emerging growth company” within meaning of the JOBS Act, which may make it more difficult for you to evaluate an investment in our company.

For additional information, see the risk factor above entitled “The JOBS Act allows us to postpone the date by which we must comply with certain laws and regulations intended to protect investors and to reduce the amount of information we have provided to you in this prospectus and will provide in our reports filed with the SEC subsequent to this offering, which may have an adverse effect on the trading price of our common stock.”

The liability of our independent registered public accounting firm is limited with respect to claims arising out of its audit report.

Our registered public accounting firm, Ernst & Young, is an Australian partnership and a member of the global network of Ernst & Young firms. The liability of Ernst & Young with respect to claims arising out of its audit report included in this prospectus is subject to the limitations set forth in the Institute of Chartered Accountants in Australia Scheme (Queensland), or ICAA Scheme, approved under the Professional Standards Act 2004 of Queensland, Australia, as amended, which we refer to as the Professional Standards Act. The ICAA Scheme, which commenced on February 1, 2008, may limit the liability of Ernst & Young for damages with respect to certain civil claims arising in, or governed by the laws of, Queensland directly or vicariously from anything done or omitted in the performance of its professional services for us, including, without limitation, its audits of our financial statements included in this prospectus, to the lesser of (in the case of audit services) ten times the reasonable charge for services provided over AUD$100,000 and up to a maximum liability of AUD$75 million (equivalent to approximately US$74.7 million, based on currency exchange rates as of June 15, 2012).

In addition, there is equivalent professional standards legislation in place in other states and territories in Australia and amendments have been made to a number of Australian federal statutes to limit liability under those statutes to the same extent as liability is limited under state and territory laws by professional standards legislation.

These limitations of liability may limit recovery upon the enforcement in Australian courts of any judgment under U.S. or foreign laws rendered against Ernst & Young based on or related to its audit report on our financial statements. However, to our knowledge the Professional Standards Act has not been subject to judicial consideration in Australia and therefore how the limitation will be applied by the courts and the effect of the limitation on the enforcement of foreign judgments are untested.

In the Demerger, Alchemia Limited’s shareholders will receive CHESS Depository Interests, or CDIs, representing shares of our common stock or, at their option, shares of our common stock. As most of Alchemia Limited shareholders are located in Australia and only the CDIs (and not our common stock) will be listed on the Australian Securities Exchange, we expect that those shareholders will generally elect to receive CDIs in the Demerger. If that occurs, we expect that those CDIs will represent a majority of our outstanding shares of common stock immediately after this offering.

Alchemia Limited will deliver the shares of our common stock represented by the CDIs distributed in the Demerger to a depositary (which we expect will be CHESS Depositary Nominees Pty Ltd, a subsidiary of the Australian Securities Exchange, or another entity authorized to act as a depositary under the ASX Settlement

-58-

Operating Rules), which will hold such shares as trustee on behalf of the holders of the CDIs. The holders of the CDIs will be the beneficial owners of, and will be entitled to exchange their CDIs for, the underlying shares of our common stock held by the depositary. In addition, holders of CDIs will generally be entitled to exercise the same voting and other rights as holders of our common stock, although they will be required to exercise those rights indirectly through the depositary unless they request the depositary to grant them a proxy to vote directly. Nonetheless, holders of CDIs will have substantially the same economic, voting and other rights as holders of our common stock and the CDIs therefore should be considered as the functional equivalents of shares of our common stock. In addition, holders of shares of our common stock will be permitted to deliver those shares to the depositary in exchange for CDIs.

The purpose of the CDIs is to facilitate trading, settlement and clearance in Australia by shareholders of Alchemia Limited who would otherwise receive shares of our common stock in the Demerger. As our common stock will not be listed on a securities exchange in Australia, Australian residents wishing to trade our common stock would be required to do so through The Nasdaq Global Market in transactions settled in U.S. dollars, which may be inconvenient due to time zone and currency differences, among other factors. However, because we plan to list the CDIs on the Australian Securities Exchange, Alchemia Limited shareholders who receive CDIs in the demerger will be able to trade those CDIs on a local Australian market in transactions settled in Australian dollars, beginning on the trading day in Australia following the date of this prospectus.

We estimate that approximately shares of our common stock, or approximately % of the estimated total number of shares of our common stock that will be outstanding immediately after this offering, calculated as of the date, in the manner and subject to the assumptions set forth under “Prospectus Summary — The Offering,” will be distributed to Alchemia Limited shareholders in the Demerger (as described under that caption, the actual number of shares that will be distributed in the Demerger will be different from the foregoing amount). All of these shares, and the CDIs evidencing these shares, will, in general, be freely tradable in the public markets in Australia, subject in some case to the lock-up agreements described under “Underwriting — Lock-up Agreements.” However, we expect that approximately shares of our common stock distributed in the Demerger (and any CDIs representing those shares), or approximately % of the estimated total number of shares of our common stock that will be outstanding immediately after this offering, will not be subject to these lock-up agreements and therefore may be traded in the public markets immediately.

The large number of shares of our common stock distributed in the Demerger that will be freely tradable in the public markets, the fact that many of those shares (and CDIs representing those shares) will not be subject to lock-up agreements, and the existence of a trading market in Australia for CDIs representing those shares, may have a material adverse effect on the market price of, and the trading market for, our common stock on The Nasdaq Global Market. Among other things:

•

shares of our common stock and CDIs representing those shares that are not to be subject to lock-up agreements may be sold in the public markets in Australia beginning on the trading day after this offering, which may have a material adverse effect on the trading price of our common stock on the Nasdaq Global Market;

•

holders of CDIs will have the right to surrender their CDIs in exchange for the underlying shares of our common stock and sell that stock on the Nasdaq Global Market, which may result in a decline in the trading price of our common stock on the Nasdaq Global Market;

•

holders of our common stock will have the right to surrender their shares to the depositary in exchange for CDIs, which may result in a decline in the trading volume and liquidity of our common stock on the Nasdaq Global Market;

•

market prices of the CDIs will be quoted in Australian dollars on the Australian Securities Exchange whereas market prices of our common stock will be quoted in U.S. dollars on the Nasdaq Global

-59-

Market. Fluctuations in the exchange rate between U.S. dollars and Australian dollars and other changes in the Australian economy affecting investors in securities traded on Australian markets may result in a decrease in demand for and a downward pressure on the trading price of CDIs, which in turn may have a material adverse effect on the trading price of our common stock on the Nasdaq Global Market; and

•

as described in the next risk factor, we may be subject to arbitrage risks that could adversely affect the market price of our common stock.

As a result, the issuance of the CDIs and the existence of an independent trading market for the CDIs may have a material adverse impact on the trading price of the common stock on the Nasdaq Global Market. Moreover, we expect that a substantial number of CDIs will be outstanding for the indefinite future, so the potential for such a material adverse impact will also continue into the indefinite future.

As a result of listing CDIs on the Australian Securities Exchange, we will be subject to the listing rules of the Australian Securities Exchange, which may strain our resources, divert management’s attention and affect our ability to manage our business or raise additional capital. The listing rules of the Australian Securities Exchange differ from, and in some cases are more restrictive than, the rules and requirements of the Nasdaq Global Market. As such, compliance with these additional rules will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. These listing rules may, in some cases, limit our ability to take certain actions that would otherwise be permitted by Nasdaq rules. We intend to apply to the Australian Securities Exchange for certain waivers from the application of certain of its listing rules; however, there is no certainty that all or any of the requested waivers will be granted or, if granted, that such waivers will afford us relief from the increased restrictions and requirements imposed by such listing rules. Increases in our costs and expenses associated with compliance with the Australian Securities Exchange listing rules will adversely impact our results of operations and financial condition.

In addition, limitations on new share issuances under Australian Securities Exchange listing rules may, in some cases, limit our ability to raise additional capital by issuing and selling shares of our common stock, if and when such additional capital is required. In particular, the Australian Securities Exchange listing rules will prohibit us from issuing, during any 12-month period, shares of our common stock in an amount greater than 15% of the total number of shares of our common stock then outstanding without the affirmative vote of the holders of a majority of the outstanding shares of our common stock. As discussed elsewhere in these prospectus, we will require substantial additional financing to develop our product candidates and execute our strategy and, because we do not have any revenues from product sales and would likely be unable to raise capital by borrowing funds, we will be dependent primarily upon issuing and selling additional shares of common stock to obtain such financing. The foregoing listing rule of the Australian Securities Exchange is substantially more restrictive than the comparable Nasdaq rule and may significantly limit our ability to raise funds by issuing and selling shares of our common stock, which may have a material adverse effect on our results of operations, financial condition and the development of our business. Moreover, seeking shareholder approval to issue common stock is likely to take time and expense and there can be no assurance that any such approval will be given.

The market price of our common stock may be adversely affected by arbitrage activities.

Investors may seek to profit by exploiting the difference, if any, in the price of our shares of common stock as reflected by the trading price of our CDIs, which will represent shares of our common stock, on the Australian

-60-

Securities Exchange and the trading price of our shares of common stock on the Nasdaq Global Market. Such arbitrage activities could cause the price of our common stock or the CDIs representing our common stock, as the case may be, in the market with the higher value to decrease to the price set by the market with the lower value or could otherwise adversely affect the market price of our common stock. These arbitrage risks may be increased by the fact that our common stock will be quoted in U.S. dollars on the Nasdaq Global Market while our CDIs will be quoted in Australian dollars on the Australian Securities Exchange, which may also give investors the opportunity to exploit the impact of fluctuations in currency exchange rates on the market price of our common stock and the CDIs.

We do not intend to pay cash dividends for the foreseeable future.

We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our cash for use in the development of our business and for general corporate purposes. Accordingly, investors seeking or expecting cash dividends should not purchase our common stock.

Since our subsidiaries, Alchemia Oncology Pty Limited and Audeo Discovery Pty Limited are both companies incorporated in Australia, substantially all of our assets are located in Australia, all of our officers, our independent accountants and one of our directors reside in Australia, and all or a substantial portion of their respective assets is located outside the United States, there is a risk that service of process, enforcement of judgments and bringing of original actions against any of them will be more difficult.

Audeo Oncology, Inc., the issuer of the common stock in this offering, is a newly formed Delaware corporation whose assets consist of primarily the capital stock of its two subsidiaries. Those subsidiaries, Alchemia Oncology Pty Limited and Audeo Discovery Pty Limited, which will hold the in-license to the VAST technology, are both companies incorporated in Australia. Apart from a small amount of office space in San Francisco, all of our facilities and all or substantially all of our other assets are located in Australia and are owned by our Australian subsidiaries. In addition, all of our officers and one of our directors reside in Australia, and the independent accountants named herein are located in Australia, and all or substantially all of their respective assets are or may be located outside the United States. As a result, it may not be possible to effect service of process within the United States upon our subsidiaries or such persons. In addition, it may not be possible to enforce against such persons judgments obtained in United States courts predicated upon the civil liability provisions of federal securities laws of the United States. There is doubt as to the enforceability in Australia, in original actions or in actions for enforcement of judgments of United States courts, of civil liabilities predicated upon the federal securities laws of the United States. In addition, our independent accountants are entitled to the protections described above under the risk factor entitled “The liability of our independent registered public accounting firm is limited with respect to claims arising out of its audit report.”

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

Provisions in our certificate of incorporation and bylaws, as amended and restated in connection with this offering, may have the effect of delaying or preventing a change of control or other takeover of us or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:

•

authorize our board of directors to issue, without further action by the stockholders, shares of preferred stock with terms, rights and preferences determined by our board of directors, which may include dividend and liquidation rights and preferences, conversion rights and voting rights;

•

require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;

-61-

•

specify that special meetings of our stockholders can be called only by our board of directors, the chairman of our board of directors, our chief executive officer or the president (in the absence of a chief executive officer) and not by our stockholders or any other persons;

•

establish an advance notice procedure for stockholder proposals to be brought before a stockholder meeting, including proposed nominations of persons for election to our board of directors;

•

establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;

•

prohibit cumulative voting in the election of directors, which means that the holders of a majority of our outstanding shares of common stock can elect all directors standing for election;

•

provide that our directors may be removed only for cause;

•

provide that vacancies on our board of directors or newly created directorships resulting from an increase in the number of our directors may be filled only by a majority of directors then in office, even though less than a quorum;

•

require the approval of our board of directors or the holders of two-thirds of our outstanding shares of common stock to amend our bylaws and certain provisions of our certificate of incorporation; and

•

provide that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising under the Delaware General Corporation Law and certain other claims.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

The foregoing provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. The foregoing provisions may also make it more difficult for a third party to take control of our company or our board of directors, which could limit the opportunity for our stockholders to receive a premium for their shares of common stock and could also adversely affect the price that some investors are willing to pay for our common stock.

USE OF PROCEEDS

We estimate that the net proceeds from our issuance and sale of common stock in this offering will be approximately $ million, or $ million if the underwriters exercise their over-allotment option in full, based on an assumed initial public offering price of $ per share, the midpoint of the estimated price range set forth on the front cover of this preliminary prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. Each $1.00 increase (decrease) in the assumed initial public offering price would increase (decrease) the net proceeds to us from this offering by $ million, assuming the number of shares offered by us, as set forth on the front cover of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions.

The principal purposes of this offering are to obtain additional capital, facilitate our future access to the public equity markets, create a public market for our common stock and generally increase the awareness of our company.

We currently intend to use the net proceeds we receive from this offering as follows:

•

approximately $ million to complete our pivotal Phase III clinical trial and related regulatory filings for HA-Irinotecan for the treatment of metastatic colorectal cancer;

•

approximately $ million to prepare for commercial-scale manufacturing of HA-Irinotecan, if approved for the treatment of metastatic colorectal cancer;

•

approximately $ million to fund our research and drug discovery activities related to additional drug candidates; and

•

the balance for general corporate purposes, including working capital and capital expenditures, which may include the acquisition or in-licensing of additional compounds, product candidates and technology, although we have no present commitments or agreements to enter into any such acquisitions.

The expected uses of the net proceeds we receive from this offering represent our intentions based upon our current plans and business conditions. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors. Accordingly, we will have broad discretion over the uses of the net proceeds in this offering and investors will be relying on the judgment of our management regarding the application of the net proceeds. In addition, it is possible that the amount set forth above will not be sufficient for the purposes described above.

Pending these uses, we intend to invest the net proceeds from this offering in interest bearing and similar investments with terms of 18 months or less, which may include interest-bearing bank accounts, money market funds, certificates of deposit and government securities.

DIVIDEND POLICY

We have never declared or paid cash dividends on our common stock. We currently intend to retain all available funds for use in the operation of our business and do not intend to pay any cash dividends on our common stock in the foreseeable future. Any future determination to declare cash dividends will be made at the discretion of our board of directors and will depend on our financial condition, operating results, capital requirements, general business conditions, relevant legal requirements, any limitations on dividends set forth in agreements to which we may become a party in the future and other factors that our board of directors may deem relevant.

CAPITALIZATION

The following table sets forth our consolidated cash and cash equivalents, short-term deposit and our consolidated capitalization as of March 31, 2012:

•

on an actual basis;

•

on a pro forma basis to reflect the Loan Conversion described above under “Prospectus Summary — Corporate Information — Corporate Reorganization” as if that transaction had occurred as of March 31, 2012.

•

on a pro forma basis to reflect (i) the transaction described in the immediately preceding bullet point and (ii) the Demerger and certain related transactions described in note (2) to the following table, as if all of the foregoing transactions had occurred as of March 31, 2012 (as indicated in note (2) to the following table, the actual number of shares of our common stock distributed in the Demerger will be different from the number of shares we have assumed for purposes of this pro forma data);

•

(1)	Gives effect to the Loan Conversion described above under “Prospectus Summary — Corporate Information — Corporate Reorganization,” as if those transactions had occurred as of March 31, 2012.

(2)

Gives effect to the transaction described in note (1) above and the Demerger, including Alchemia Limited’s anticipated transfer to us of cash and cash equivalents in the amount of $ and other assets in the amount of $ and our anticipated assumption of $ of Alchemia Limited’s employee entitlements liabilities in connection with the Demerger, as described in “Arrangements between Audeo Oncology, Inc. and Alchemia Limited,” and (y) the assumed distribution of shares of our common stock (or CDIs representing those shares) to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012, and the distribution of one share of our common stock for every outstanding ordinary shares of Alchemia Limited, as if all of the foregoing transactions had occurred as of March 31, 2012. This pro forma data is illustrative only, does not purport to reflect what our actual cash and cash equivalents, short-term deposit or capitalization would have been had the foregoing transactions occurred as of that date and will change based on the actual amount of Alchemia Limited’s assets that are transferred to us and the actual amount of Alchemia Limited’s liabilities that we assume in the Demerger and the actual number of shares of our common stock distributed in the Demerger. As noted above under “Prospectus Summary — The Offering,” the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012 and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. As a result, the actual number of shares of our common stock that will be distributed in the Demerger will be different than the number of shares we have assumed for the purposes of this pro forma data. Each share increase (decrease) in the estimated number of shares of our common stock distributed in the Demerger would increase (decrease) the number of shares of our common stock issued and outstanding, pro forma for the Demerger, as reflected in the common stock line item in the table above by shares.

(3)

Gives effect to the transactions described in notes (1) and (2) above and the sale of shares of common stock in this offering at an assumed public offering price of $ per share (the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus), after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as if those transactions had occurred as of March 31, 2012. This pro forma as adjusted information is illustrative only, does not purport to reflect what our actual cash and cash equivalents, short-term deposit or capitalization would have been had the foregoing transactions occurred as of that date and will change based on the actual amount of Alchemia Limited’s assets that are transferred to us, the actual amount of Alchemia Limited’s liabilities that we assume, the actual number of shares of our common stock distributed in the Demerger, the actual initial public offering price and other terms of this offering determined at pricing and the actual offering expenses payable by us. Each $1.00 increase (decrease) in the assumed initial public offering price of $ per share, the midpoint of the estimated price range set forth on the front cover of this preliminary prospectus, would increase (decrease) each of cash and cash equivalents, additional paid-in capital, total stockholders’ deficit and total capitalization by approximately $ million, assuming that there is no change in the amount of assets transferred or liabilities assumed in the Demerger, that share of our common stock are distributed to Alchemia Limited shareholders in the Demerger, that the number of shares offered by us, as set forth on the front cover of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. As discussed in

-68-

note (2) above, the actual number of shares of our common stock distributed in the Demerger will be different from the number of shares we have assumed for purposes of this pro forma as adjusted data. Each share increase (decrease) in the estimated number of shares of our common stock distributed in the Demerger would increase (decrease) the number of shares of our common stock issued and outstanding, pro forma as adjusted for this offering, as reflected in the common stock line item in the table above by shares. The pro forma as adjusted data assumes that we initially invest all of the estimated net proceeds from this offering in cash and cash equivalents and does not give effect to our use of proceeds from the sale of shares of common stock in this offering for the other purposes set forth under “Use of Proceeds.”

The actual, pro forma and pro forma as adjusted amounts in the above table exclude:

•

shares of our common stock issuable upon the exercise of the Warrants that we will issue after this offering to investors who purchased ordinary shares of Alchemia Limited in a private placement and that will have an exercise price equal to 130% of the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price for such period as the Average Trading Price). The number of shares of our common stock, or the Warrant Shares, that will be issuable upon exercise of those Warrants and the exercise price per share will be calculated as described in “Prospectus Summary — The Offering.” However, because the number of Warrant Shares and exercise price both depend upon the actual Average Trading Price following this offering and the number of Warrant Shares also depends upon the exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. See “Prospectus Summary — The Offering” for an analysis showing how changes in the Average Trading Price change the number of Warrant Shares issuable upon exercise of the Warrants and the exercise price of the Warrants and how changes in the currency exchange rate affect the number of Warrant Shares issuable upon such exercise. In addition, the number of Warrant Shares and/or the exercise price are subject to adjustment pursuant to the terms of the Warrants, including in the event of stock splits, stock combinations and similar events as well as in the event of dividends or other distributions on our shares of common stock;

DILUTION

If you invest in our common stock, your interest in our company will be diluted to the extent of the difference between the amount per share paid by purchasers of shares of common stock in this initial public offering and the pro forma as adjusted net tangible book value per share of common stock immediately after this offering.

Dilution results from the fact that the per share offering price of our common stock is substantially in excess of the book value per share attributable to the existing stockholders (for purposes of this discussion of dilution, we are including Alchemia Limited shareholders who receive shares of our common stock or CDIs representing those shares in the Demerger as “existing stockholders”). Net tangible book value per share represents the amount of our total tangible assets less our total liabilities, divided by the shares of common stock outstanding. As of March 31, 2012, we had a net tangible book value of approximately $ , or approximately $ per share.

After giving effect to the Demerger, including the transfer of $ of cash and cash equivalents from Alchemia Limited to us, and our assumption of $ of certain of Alchemia Limited’s liabilities, pursuant to the Demerger, as described under “Arrangements between Audeo Oncology, Inc. and Alchemia Limited,” and the assumed distribution of shares of our common stock to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution of one share of our common stock for every outstanding ordinary shares of Alchemia Limited, as if those transactions had occurred as of March 31, 2012, our pro forma net tangible book value as of that date would have been approximately $ , or approximately $ per share of our outstanding common stock. Likewise, after giving effect to the transactions described in the immediately preceding sentence and the sale of shares of our common stock in this offering at an assumed initial public offering price of $ per share, the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as if those transactions had occurred as of March 31, 2012, our pro forma as adjusted net tangible book value as of that date would have approximately $ , or approximately $ per share of our common stock. This represents an immediate increase in pro forma as adjusted net tangible book value of $ per share to existing stockholders and an immediate dilution of $ per share to new investors purchasing shares in this offering. As noted above under “Prospectus Summary — The Offering,” the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012 and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. As a result, the actual number of shares of our common stock distributed in the Demerger will be different from the number of shares we have assumed for purposes of the pro forma and pro forma as adjusted data set forth in this section and our actual pro forma as adjusted net tangible book value and dilution per share and the other information in this section that gives effect to the Demerger will be different from the amounts and other information set forth in this section.

Pro forma as adjusted net tangible book value per share after the Demerger and this offering

Pro forma as adjusted dilution per share to new investors in this offering		$

The dilution information discussed above is illustrative only and will change based on the actual amount of assets transferred to, and liabilities assumed by, us in the Demerger, the actual initial public offering price and other terms of this offering determined at pricing, the actual offering expenses payable by us and the actual number of shares of our common stock distributed in the Demerger. Each $1.00 increase (decrease) in the assumed initial public offering price of $ per share, the midpoint of the estimated price range set forth on the front cover of this preliminary prospectus, would increase (decrease) our pro forma as adjusted net tangible book value by approximately $ per share and the dilution in pro forma as adjusted net tangible book value per share to new investors in this offering by approximately $ per share, assuming the number of shares offered by us, as set forth on the front cover of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. Each share increase (decrease) in the number of shares of our common stock distributed in the Demerger would decrease (increase) our pro forma as adjusted net tangible book value per share by approximately $ per share and would increase (decrease) the dilution in pro forma as adjusted net tangible book value per share to new investors in the offering by approximately $ per share, assuming an initial public offering price of $ per share and that the number of shares offered by us, as set forth on the front cover of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters exercise their over-allotment option in full, the pro forma as adjusted net tangible book value per share of our common stock after this offering would be approximately $ per share of common stock and the pro forma as adjusted dilution per share to new investors in this offering would be approximately $ per share of our common stock, in each case calculated as described above.

The following table summarizes, on a pro forma as adjusted basis as of March 31, 2012, the total number of shares of common stock purchased from us, the total consideration paid to us, and the average price per share paid to us by existing stockholders and by new investors purchasing shares in this offering, after giving effect the assumed distribution of shares of our common stock to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution to Alchemia Limited shareholders of one share of our common stock for every outstanding ordinary shares of Alchemia Limited, and our sale of common stock in this offering at an assumed initial public offering price of $ per share, the midpoint of the estimated price range set forth on the front cover of this preliminary prospectus, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as if those transactions had occurred as of March 31, 2012. For purposes of the following table, we have included shares distributed pursuant to the Demerger as shares purchased by existing stockholders at an assumed average purchase price of $ per share; such average purchase price reflects the fact that the deemed consideration we received for

SELECTED CONSOLIDATED FINANCIAL DATA

You should read the following selected consolidated financial data in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes, all included elsewhere in this prospectus. As we are a subsidiary of Alchemia Limited, our consolidated financial statements are derived from the consolidated financial statements and accounting records of Alchemia Limited. Accordingly, our consolidated financial statements include allocations of expenses, primarily salaries and benefits (including stock-based compensation) of officers and other employees of Alchemia Limited, expenses for compensation and reimbursement paid to directors of Alchemia Limited and insurance expenses incurred by Alchemia Limited. These expenses have been allocated based on our estimated share of Alchemia Limited’s expenses. Although we believe that these allocation methodologies are reasonable, the selected consolidated financial information set forth below and our consolidated financial statements do not purport to reflect the results of operations, financial position and cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future.

We derived the selected consolidated statement of operations data for the years ended June 30, 2010 and June 30, 2011 and the selected consolidated balance sheet data as of June 30, 2010 and June 30, 2011 from our audited consolidated financial statements included elsewhere in this prospectus. The selected statement of operations data for the nine months ended March 31, 2011 and March 31, 2012 and the selected consolidated balance sheet data as of March 31, 2012 have been derived from our unaudited interim financial statements included elsewhere in this prospectus. The selected statement of operations data for the period from inception to March 31, 2012 have been derived from our unaudited consolidated financial statements included elsewhere in this prospectus. Our historical results of operations and financial condition do not purport to be indicative of our results of operations or financial condition as of any future date or for any future period.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this prospectus. This discussion contains forward looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward looking statements as a result of various factors, including those set forth under “Risk Factors” and “Special Note Regarding Forward-Looking Statements” or in other parts of this prospectus. The last day of our fiscal year is June 30. Our fiscal quarters end on September 30, December 31, March 31, and June 30. Fiscal 2012, our current fiscal year, will end on June 30, 2012.

Our consolidated financial statements are derived from the consolidated financial statements and accounting records of Alchemia Limited. Our consolidated financial statements include allocations of expenses, primarily salaries and benefits (including stock-based compensation) of officers and other employees of Alchemia Limited, expenses for compensation and reimbursement paid to directors of Alchemia Limited and insurance expenses incurred by Alchemia Limited. These expenses have been allocated based on our estimated share of Alchemia Limited’s expenses. Although we believe that these allocation methodologies are reasonable, the financial information included in this discussion and our consolidated financial statements do not necessarily reflect the results of operations, financial position and cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future.

Overview

We are a late stage biopharmaceutical company primarily focused on utilizing our Hyaluronic Acid Chemotransport Technology, or HyACT, to target cancer drugs preferentially to tumor cells to enhance drug activity. HyACT is a flexible platform technology designed to increase the effectiveness of anti-cancer agents without increasing treatment toxicity. We seek to reduce the risks related to drug development by using known anti-cancer drugs, and aim to enhance their commercial value by improving their effectiveness. Our lead HyACT product candidate, HA-Irinotecan, is currently in a pivotal Phase III clinical trial for metastatic colorectal cancer, or mCRC. HA-Irinotecan is also in an investigator-sponsored Phase II clinical trial for small cell lung cancer, or SCLC. We also have two other HyACT product candidates that have successfully completed Phase I clinical trials. In addition to our current clinical-stage product candidates, we aim to develop a pipeline of product candidates by exploiting our significant know-how in cancer stem cell biology and cancer metabolism combined with the Versatile Assembly on Stable Templates, or VAST, small molecule drug discovery technology that we will in-license.

Our business was in the past conducted through Alchemia Oncology Pty Limited, an Australian company that we sometimes refer to as Alchemia Oncology. Alchemia Oncology, which was previously known as

-76-

Meditech Research Ltd., was acquired by Alchemia Limited in 2006 and was a wholly-owned direct subsidiary of Alchemia Limited. In June 2012, Alchemia Limited effected a reorganization, which we sometimes refer to as the Reorganization, pursuant to which we became a wholly-owned subsidiary of Alchemia Limited and Alchemia Oncology became a wholly-owned direct subsidiary of ours and a wholly-owned indirect subsidiary of Alchemia Limited. Accordingly, the description of our business and our consolidated financial statements and other financial information included in this prospectus as of the dates and for the periods prior to the Reorganization reflect the business, results of operations and financial position of Alchemia Oncology, and the description of our business and our consolidated financial statements and other financial information as of the dates and for the periods from and after the date of Reorganization reflect the business, results of operations and financial condition of Audeo Oncology, Inc. and its consolidated subsidiaries, in each case unless otherwise expressly stated or the context otherwise requires.

We were formed for the purpose of (a) acquiring Alchemia Oncology Pty Limited and forming our other subsidiary, Audeo Discovery Pty Limited, an Australian company organized to in-license the VAST small molecule drug discovery technology owned by Alchemia Limited, and (b) demerging from Alchemia Limited as an independent public company with shares of our common stock listed on the Nasdaq Global Market and CHESS Depository Interests, or CDIs, representing shares of our common stock listed on the Australian Security Exchange. Our business and operations consist solely of the business and operations of Alchemia Oncology Pty Limited and Audeo Discovery Pty Limited, both of which are our wholly-owned subsidiaries. Contemporaneously with this offering, we intend to complete our demerger, or the Demerger, from Alchemia Limited pursuant to a Scheme of Arrangement that must be approved by the Federal Court of Australia and by more than 75% in voting interest and a majority in number of Alchemia Limited’s shareholders present and voting at a meeting of shareholders. This meeting of shareholders is anticipated to occur in late September or early October 2012.

Pursuant to the Demerger, Alchemia Limited, which currently owns all of the outstanding shares of our common stock, will distribute one share of our common stock to the shareholders of Alchemia Limited (or a depositary on their behalf) for every ordinary shares of Alchemia Limited that they hold as of the record date for the Demerger, which is expected to be approximately , 2012, with fractional shares of our common stock that would otherwise be distributed to Alchemia Limited shareholders in the Demerger being rounded upwards to the nearest whole share. To the extent that the number of shares of our common stock currently owned by Alchemia Limited is insufficient to permit the distribution of one share of our common stock for every ordinary shares of Alchemia Limited outstanding at the time of the Demerger, we will issue such number of additional shares of our common stock to Alchemia Limited as may be necessary to permit that distribution to be made in full. In connection with the Demerger, Alchemia Limited anticipates that it will transfer cash and cash equivalents to us in the amount of $ and we anticipate that we will assume $ of Alchemia Limited’s employee entitlement liabilities, as described in “Arrangements between Audeo Oncology, Inc. and Alchemia Limited.”

None of our product candidates has received regulatory approval and, to date, we have not generated any revenues from the sale of products and our parent company, Alchemia Limited, has provided all of the funds necessary for our operations. We have experienced net losses in each year since our inception. We have never been profitable and, as of March 31, 2012 we had an accumulated deficit of $37,135,937. We expect our net losses to continue and to increase as the continued development of our HyACT product candidates will require significant additional expenditure for a variety of activities, including continued preclinical studies, clinical trials, research and development, manufacturing development and regulatory approvals and because of the significant additional expenses we will incur as a result of being a public company. We do not expect to generate revenue from the sale of our products until one or more of our product candidates is approved for sale by the FDA and successfully commercialized and, even if a product candidate receives regulatory approval, there can be no assurance that it will generate revenue. We cannot assure you that any of our product candidates will receive FDA approval in a timely manner or at all or, if approved, will be successfully commercialized. We may not obtain regulatory approval for many reasons, including among others:

•

our inability to complete our ongoing and planned clinical trials in a timely manner

•

the results of our clinical trials may not effectively demonstrate the safety and efficacy of our product candidates;

•

the data from our clinical trials may not support a New Drug Application;

•

if any of our product candidates receives regulatory approval, the labeling for that product candidate may not permit us to charge a price in excess of the price of generic anti-cancer drugs;

•

the FDA or non-U.S. regulatory authorities may disagree with the results of our clinical trials; or

•

the FDA or non-U.S. regulatory authorities may change their approval policies and procedures.

If we are unable to obtain regulatory approval of any of our product candidates, we will be unable to generate revenue and may never become profitable and, even if regulatory approval is granted for one or more of our product candidates, we may be unable to successfully commercialize those product candidates.

Critical Accounting Policies

This management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to research and development costs and stock-based compensation. We base our estimates on historical experience, known trends and events and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements appearing elsewhere in this prospectus, we believe the following accounting policies involve a greater degree of judgment and complexity. Accordingly, we believe these are the most critical to the process of making significant judgments and estimates in the preparation of our consolidated financial statements.

-78-

Government Grant Income

Government grants are recognized as income when there is substantial assurance that all related conditions will be met. When we receive grants before they are earned, such grants are recognized as a liability in the balance sheet.

When the grant relates to an expense item, we match the grant with the costs that the grant is intended to compensate and recognize the grant as income over the periods in which the related cost is incurred.

When the grant relates to an asset, the grant is released to the income statement over the expected useful life of the relevant asset by equal annual installments.

We received one Australian Government research grant under the Commercial Ready Grant for our HA-Irinotecan program. The completion date for the project was February 29, 2009. We have the obligation to report the progress of the project five years post completion date and have done so to date. The Australian Government may require us to repay all or some of the amount of the grant together with interest in any of the following circumstances:

•

we fail to use our best endeavors to commercialize the relevant grant project within a reasonable time of completion of the project;

•

upon termination of a grant due to our breach of the agreement or insolvency;

•

there is change in control or ownership of our company that the Australian Government reasonably considers to have an adverse effect on our ability to comply with any of our obligations in the grant agreement; or

•

we cease to carry on a substantial part of our business.

Technical failure of the grant funded project does not, in and of itself, constitute failure to use best endeavors to commercialize the relevant grant project and we believe that we have complied with our obligation to commercialize the project funded by the grant program. The total amount received since the commencement of the Commercial Ready Program is $1,675,201, which includes $166,345 received prior to our inception.

Research Funding Income

Prior to entering into the supply agreement and royalty agreement with Novozymes Biopharma DK A/S, or Novozymes, described below under “—Contractual Obligations and Commitments,” we had two agreements with Novozymes pursuant to which we received $433,733 of funding. Subsequent to the achievement of the substantive milestones specified in these agreements relating to our Phase II clinical trials of HA-Irinotecan, $253,069 and $180,664 were recognized as research and development income in the years ended June 30, 2007 and 2009, respectively. After the achievement of the last milestone of our Phase II clinical trials, on July 1, 2009, these agreements were terminated by mutual agreement of the parties. On the same date, the royalty agreement and supply agreement, described below under “—Contractual Obligations and Commitments,” were entered into. See “—Contractual Obligations and Commitments.”

Research and Development Expenses

Research and development expenses are expensed when incurred. Such costs include, but are not limited to, direct salaries and benefits, stock-based compensation expense, consultant costs, patient recruitment fees, contract research costs, laboratory expenses, rent and utilities. Costs for certain development activities, such as

-79-

clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to us by our vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid research and development or other payables.

Stock-Based Compensation

Equity awards granted to our employees and non-employees (i.e., independent contractors) by Alchemia Limited under its stock option plan consist of ordinary shares of Alchemia Limited and options to purchase Alchemia Limited’s ordinary shares, and are accounted for under Accounting Standards Codification, or ASC, 718-10, “Share-Based Payment” and ASC 505-50, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services”, respectively. The stock-based compensation expenses for employees and non-employees (i.e., independent contractors) employed by our subsidiary, Alchemia Oncology Pty Limited relating to these equity awards are recognized in our financial statements with a corresponding entry to additional paid-in capital. A portion of stock-based compensation expenses for employees of Alchemia Limited that have a percentage of their salary allocated to us in accordance with our allocation of general and administrative expenses accounting policy described under the caption “Allocation of general and administrative expenses” in note (2) to our financial statements included elsewhere herein, have been recognized in our financial statements as general and administrative expense with a corresponding entry to related party loan. We do not currently have our own equity incentive plans but plan to adopt our 2012 Equity Incentive Plan in connection with this offering. See “Prospectus Summary — The Offering.”

All grants of stock options and ordinary shares to employees are recognized in our financial statements based on their grant date fair values. We have elected to recognize stock-based compensation expense using the straight-line method over the period during which the employee is required to perform service in exchange for the award. For the awards granted to non-employees, we record stock-based compensation expense equal to the fair value of the stock options and ordinary shares at the measurement date, which is determined to be the earlier of the performance commitment date or the service completion date and is recognized using the accelerated method. We use the Black-Scholes option pricing model in determining the fair value of the equity awards and ordinary shares granted.

ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Forfeiture rate is estimated based on historical and future expectation of employee turnover rate and is adjusted to reflect future change in circumstances and facts, if any. Stock-based compensation expense is recorded net of estimated forfeitures such that expense was recorded only for those stock-based awards that are expected to vest. To the extent we revise this estimate in the future, stock-based compensation expense could be materially impacted in the period of revision, as well as in following periods. For the periods presented, we estimated that the forfeiture rate for both our management and non-management employees was zero.

Income Taxes

We use the liability method of accounting for income taxes as set forth in the authoritative guidance for income taxes. Under this method, we recognize deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the respective carrying amounts and tax bases of our assets and liabilities.

We continue to assess the realizability of our deferred tax assets, which primarily consist of net operating loss, or NOL, carry-forwards for Australia income tax purposes. In assessing the realizability of these deferred

-80-

tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. We establish valuation allowances when necessary to reduce deferred tax assets to the amounts expected to be realized. The factors used to assess the likelihood of realization include our latest forecast of future operating results and available tax planning strategies that could be implemented to realize the net deferred tax assets.

Audeo Oncology, Inc. is a newly incorporated company in the United States and currently has no carry-forward tax losses for U.S. or other tax purposes. Alchemia Oncology Pty Limited, our wholly-owned subsidiary, had net operating tax loss carry-forwards for Australian tax purposes of approximately $68.0 million, $64.7 million and $47.1 million as of March 31, 2012 and June 30, 2011 and 2012, respectively, which can be carried forward indefinitely. These also may be adjusted if we are unable to comply with the recognition criteria for carry forward tax losses under Australian tax laws. Future events such as capital injections and changes in our business, capital structure or ownership require evaluation as to the impact on continued availability of historical tax losses to offset future income, if any. Pursuant to Australian tax law, tax losses may not be available and would thus be derecognized (i.e. lost) where there has been a greater than 50% change in the cumulative

ownership of Alchemia Oncology Pty Limited combined with a change in our business or capital structure. Accordingly, certain years’ tax losses may fail the continuity of ownership test, or COT, and later years’ tax losses may pass. If a company does not satisfy the COT in respect of a particular loss year, it must instead satisfy the same business test, or SBT, to be eligible to utilize prior year losses. The SBT broadly requires the company to carry on the same business for the entire year in which it seeks to recoup losses as it did when it failed COT. We have analyzed these requirements with our Australian tax adviser and believe that, presently, none of Alchemia Oncology’s net operating tax loss carry-forwards will be de-recognized based on past cumulative changes in ownership or as a result of the distribution of shares of our common stock in the Demerger and the issuance of shares of our common stock in this offering, although there can be no assurance in this regard. As a result of these tax loss carry-forwards, we have significant deferred tax assets; however, due to our lack of earnings history, realization of these deferred tax assets is not more likely than not; therefore the deferred tax assets have been fully offset by a valuation allowance.

We have a history of net losses and there can be no assurance that we will ever achieve or sustain profitability. However, if any of our product candidates is approved for commercial sale and we start to generate revenue, we may determine that there is sufficient positive evidence to support a reversal of, or decrease in, the valuation allowance. If we were to reverse all or some part of our valuation allowance, our financial statements in the period of reversal would likely reflect an increase in assets on our balance sheet and a corresponding tax benefit to our statement of operations in the amount of the reversal.

Because Audeo Oncology, Inc. is a Delaware corporation with its executive offices in California, we became subject to U.S. and California income taxes in calendar year 2012.

We adopted Accounting Standards Codification (ASC) 740-10, Accounting for Uncertainty in Income Tax — an Interpretation of FASB Statement No. 109. We analyzed our tax position in all jurisdictions where we are required to file an income tax return and concluded that we do not have any material unrecognized tax benefits. We intend to file a U.S. income tax return as well as returns for any state jurisdiction in which we are authorized to conduct business. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefit within the provision for income taxes on the statement of operations. We have no interest or penalties accrued for any unrecognized tax benefits for any periods presented in our consolidated financial statements included elsewhere herein.

Our annual provision for income taxes and the determination of the resulting deferred tax assets and liabilities involve a significant amount of management judgment. Management’s judgments, assumptions and estimates relative to the current provision for income taxes take into account current tax laws, our interpretation of current tax laws and possible outcomes of current and future audits conducted by foreign and domestic tax authorities. We operate within federal, state and international taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues that may require an extended period of time to resolve.

Financial Operations Overview

Research and Development Expense

Research and development activities are the cornerstone of our business and research and development expenses consist of in-process research and development that we expensed in 2006 in connection with our acquisition of Meditech and costs associated with our research activities, including our drug discovery efforts. These costs include, but are not limited to, direct salaries and benefits, stock-based compensation expense, consultant costs, patient recruitment fees, contract research costs, laboratory expenses, rent and utilities. We expense research and development expenses as incurred. From inception through March 31, 2012 we have incurred $34,842,799 for research and development expense.

General and Administration Expense

General and administration expenses mainly consist of compensation for our executive and administrative personnel, including stock-based compensation, and, in the future, will also include compensation expense, including stock-based compensation expense, for our board of directors. Other general and administration expenses also include facility costs not otherwise included in research and development expenses, patent related costs, insurance, travel and professional fees for legal and accounting services. From inception through March 31, 2012 we have incurred $4,868,514 for general and administrative expense.

Government Grant Income

Grant income consists of grants received from the Government of Australia. From inception to March 31, 2012, we received $1,508,856 of grant income. However, we have not received any grant income subsequent to fiscal 2009 and there is no certainty that we will receive any future grant funding.

Research Funding Income

Research funding income received from inception through March 31, 2012 consists of approximately $434,000 of income related to a Research and Development and Clinical Trial Agreement, which we refer to as the RD&CT agreement, with Novozymes to fund Phase II trial expenses for metastatic colorectal cancer. However, the RD&CT agreement has been terminated, we have not received any research funding income subsequent to fiscal 2009 and there is no certainty that we will receive any future research funding income.

Loan Conversion

In the past, our business has been financed by Alchemia Limited and, as of March 31, 2012, approximately $27.9 million of related party loans made by Alchemia Limited to us were outstanding. After giving effect to additional loans made to us by Alchemia Limited subsequent to March 31, 2012 (including a loan of approximately $7.5 million made on June 28, 2012), and including effects of foreign currency translation of approximately $0.9 million, a total of approximately $37.6 million of related party loans was outstanding as of June 28, 2012. On June 28, 2012, Alchemia Limited converted all of these related party loans into newly-issued ordinary shares of Alchemia Oncology and, as a result, the loans were cancelled. We subsequently issued 7.5 million shares of our common stock to Alchemia Limited on June 28, 2012 and, in return, Alchemia Limited transferred all of Alchemia Oncology’s outstanding ordinary shares to us.

Total Other Income

Total other income includes interest income and other income as discussed below.

Interest income consists of interest earned on our cash and cash equivalents.

Other income received from inception through March 31, 2012 includes $314,698 of other income related to an amount received from Jagotec AG for the relinquishment of rights for the sale of Solarase in Australia and New Zealand in 2007. From inception to March 31, 2012, we also received $119,117 as royalties from a licensing agreement with Jagotec AG entered into in connection with the sale of Solarase in 2002. This agreement expires in August 2012.

As described under “Arrangements between Audeo Oncology, Inc. and Alchemia Limited,” we will provide certain accounting, treasury, management, tax support, investor relations, information technology and other administrative services to Alchemia Limited for the six months after the implementation of the Demerger. Under the agreement, Alchemia Limited must pay us a monthly service charge (calculated on a cost recovery basis) and our out-of-pocket expenses in providing the services.

Results of Operations

Our functional currency for accounting purposes is the Australian dollar; however our reporting currency is the U.S. dollar. As a result, in preparing our consolidated financial statements for purposes of this prospectus and going forward in our annual and quarterly reports, we must convert amounts recorded in our functional currency to our reporting currency. For revenues and expenses reported in any period, we use the average currency exchange rate between U.S. dollars and Australian dollars, based on the average buying rates for the 24 hour period ending 22:00 Universal Coordinated Time on the respective prior days, published at www.oanda.com/currency. For assets and liabilities, we use the current currency exchange rate as at the end of the period, based on the same source. Given the fluctuations in currency exchange rates, we may experience changes in reported amounts from period to period that occur primarily as a result of these fluctuations and that are not reflective of actual changes in our business or operations.

Currently, we are exposed to foreign exchange risk, particularly with the U.S. dollar and Australian dollar, as a result of certain research and development activities that are undertaken internationally. It is our policy to limit the use of financial derivatives and seek risk mitigation through natural hedges. These natural hedges include the maintenance of US dollar and Australian bank accounts and deposits to primarily facilitate the payment of research and development activities. Because our functional currency is the Australian dollar our reported financial results are subject to fluctuation resulting from changes in the Australian dollar to U.S. dollar exchange rate.

Comparison of Nine Months Ended March 31, 2012 and 2011

Research and Development Expense

Research and development expense increased by $550,031, or 14.5%, to $4,344,200 for the nine months ended March 31, 2012 as compared with $3,794,169 for the nine months ended March 31, 2011. This increase was primarily the result of an increase in clinical trial costs, consultant costs, drug supply-related costs and travel costs as we advanced our pivotal Phase III clinical trials in Europe and other sites.

Research and development expenses represented 85.0% of our total operating expenses for the nine months ended March 31, 2012 compared with 84.6% for the nine months ended March 31, 2011. We expect research and development expenses to continue to increase, both in absolute dollars and as a percentage of our total operating expenses, as we devote substantial resources to research and development to support the continued development

-83-

of our product candidates. We also expect to incur research and development costs advancing the oncology drug discovery efforts and the VAST small molecule drug discovery technology that we intend to in-license prior to the Demerger.

General and Administrative Expense

General and administrative expense increased by $74,171, or 10.7%, to $764,566 for the nine months ended March 31, 2012 as compared with $690,395 for the nine months ended March 31, 2011. This increase was largely due to an increase in salary and wages.

We expect that our general and administration expenses will increase substantially following the Demerger and the commencement of operations as an independent corporation, particularly as a result of expenses associated with our obligations as a public company. Further we intend to continue to expand our infrastructure to support our growing research and development.

Comparison of Years Ended June 30, 2011 and 2010

Research and Development Expense

Research and development expense increased by $3,848,579, or 122.7%, to $6,985,879 for the year ended June 30, 2011 as compared with $3,137,300 for the year ended June 30, 2010. This increase was mainly a result of an increase in consultant and drug-supply related costs as we prepared for our pivotal Phase III clinical trial, which commenced patient enrollment in fiscal 2012.

General and Administrative Expense

General and administrative expenses increased by $63,982, or 7.4%, to $929,071 for the year ended June 30, 2011 as compared with $865,089 for the year ended June 30, 2010. This increase was largely due to an increase in salary and wages.

Liquidity and Capital Resources

Sources of funding

Since inception, our cash needs have been funded entirely by our parent company, Alchemia Limited. As of March 31, 2012, we had approximately $27.9 million of outstanding borrowings owing to Alchemia Limited. The loan is non-interest bearing with no maturity date and no repayment terms. On June 28, 2012, Alchemia Limited made an additional loan to us of approximately $7.5 million, increasing our cash balance and increasing the aggregate amount of outstanding related party loans to approximately $37.6 million, including effects of foreign currency translation of approximately $0.9 million. On June 28, 2012, Alchemia Limited converted all of these related party loans into newly-issued ordinary shares of Alchemia Oncology and, as a result, the loans were cancelled. We sometimes refer to our receipt of the cash proceeds from the additional loan made to us on June 28, 2012, the conversion of all of these outstanding related party loans into newly-issued ordinary shares of Alchemia Oncology and the cancellation of these loans as the loan conversion.

Alchemia Limited will not have any direct or indirect obligation to provide us with loans or other funds subsequent to the date of the Demerger and we understand that Alchemia Limited has no intention of doing so. Accordingly, we will be entirely dependent upon our own capital resources independent of Alchemia Limited in order to finance our business going forward. In addition, we have experienced net losses since inception and, as of March 31, 2012, we had an accumulated deficit of $37,135,937, and expect to continue to incur net losses for the foreseeable future.

Cash Flows

Operating Activities

The cash flows provided by (used in) operating activities primarily resulted from our net loss, adjusted for non-cash items, and changes in our operating assets and liabilities.

Operating activities used $87,062 of cash during the nine months ended March 31, 2012. We had a net loss of $5,099,381, which included non-cash stock-based compensation expenses of $88,138, non-cash stock-based compensation expenses of Alchemia Limited employees allocated to us of $81,545, and depreciation expenses of $182,897. Changes in our operating assets and liabilities provided $4,659,739 of cash during the nine month period, primarily due to increases of $5,991,557 in our related party loan from Alchemia Limited, partially offset by an increase in prepaid research and development costs of $901,517 and a decrease in our trade and other payables of $444,673.

Operating activities provided $293,140 of cash during the nine months ended March 31, 2011. We had a net loss of $4,483,386, which included non-cash stock-based compensation expenses of $82,754 and depreciation expenses of $46,426. Changes in our operating assets and liabilities provided $4,647,346 of cash during the nine month period, primarily due to increases of $6,333,701 in our related party loan from Alchemia Limited, partially offset by an increase in prepaid research and development costs of $1,490,694 and a decrease in our trade and other payables of $232,679.

Operating activities provided $644,341 of cash in the year ended June 30, 2011. We had a net loss of $7,913,268, which included non-cash stock-based compensation expenses of $84,837, non-cash stock-based compensation expenses of Alchemia Limited employees allocated to us of $30,625, and depreciation expenses of $97,626. Changes in our operating assets and liabilities provided $8,344,521 of cash during the year, primarily due to increases of $8,409,955 in our related party loan from Alchemia Limited, partially offset by an increase in prepaid research and development costs of $173,590.

Operating activities used $120,420 of cash in the year ended June 30, 2010. We had a net loss of $3,959,931, which included non-cash stock-based compensation expenses of $158,436, non-cash stock-based

-85-

compensation expenses of Alchemia Limited employees allocated to us of $179,621, and depreciation expenses of $32,493. Changes in our operating assets and liabilities provided $3,468,961 of cash during the year, primarily due to increases of $3,142,861 in our related party loan from Alchemia Limited and an increase in our trade and other payables by $366,144, partially offset by a decrease in employee provisions of $68,099.

Investing Activities

Cash used in investing activities was for the purchase of property and equipment. We used $27,131 in the nine months ended March 31, 2012 to purchase computer hardware and software, $331,014 in the nine months ended March 31, 2011 to purchase laboratory equipment, $539,378 in the year ended June 30, 2011 to purchase laboratory equipment and computer hardware and $648 in the year ended June 30, 2010 to purchase equipment.

Operating and Capital Expenditure Requirements

Since our inception in 2006, we have spent $34,842,799 on research and development, $4,868,514 on general and administrative expenses and $676,904 on capital equipment. We believe that the net proceeds raised from this offering and our cash and cash equivalents will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, this estimate is based on numerous assumptions and uncertainties that may be proven wrong and as such, we could use our available financial resources sooner than we currently expect. Our forecast of the period of time that our financial resources will be adequate to support operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed under “Risk Factors” and “Special Note Regarding Forward-Looking Statements.” In light of the numerous risks and uncertainties associated with the development and, if any of our product candidates receive regulatory approval, commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated pre-clinical studies, clinical trials or other research and development activities. Our future funding requirements will depend on a number of factors including:

•

the scope, results, rate of progress, timing and costs of pre-clinical studies and clinical trials and other development activities;

•

the costs and timing of seeking and obtaining regulatory approvals;

•

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

•

the costs of securing coverage, payment and reimbursement of our product candidates, if any of our product candidates receive regulatory approval;

•

the effects of completing clinical, technological and market developments;

•

the costs of hiring additional employees as we develop our business;

•

additional costs as a result of our being a public company;

•

the costs of remediating a material weakness in our internal system of financial control, including costs of hiring a controller and an outside firm proficient in U.S. GAAP;

•

if any product candidates receive regulatory approval, the costs of developing any sales and marketing organization that we may seek to establish to commercialize those product candidates; and

•

the terms, timing and cash requirements of any future acquisition, collaborative arrangements, licensing of product candidates or investing in businesses, product candidates and technologies.

-86-

We expect that our cash requirements will increase substantially in the future, both as a result of the significant costs associated with clinical trials and preclinical studies, preparing for commercial manufacturing, and our obligations as a public company. In addition, although we are currently not a party to any agreement or letter of intent with respect to potential investments in or acquisitions of other businesses or technologies, we may enter into these types of agreements in the future, which could require us to seek additional financing. Finally, as discussed above, we believe that the net proceeds raised from this offering together with our cash and cash equivalents will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditures for only a limited period of time, and we therefore will require external financing in order to complete our current clinical trials and otherwise continue our business. We will therefore need to raise substantial additional capital in the future, and there can be no assurance that we will be able to do so on terms we consider acceptable, or at all. If we are unable to raise additional funds when needed we may not be able to continue development of our product candidates or we could be required to delay, scale back or eliminate some or all of our development programs and other operations. We may seek to raise additional funds through public or private equity or debt financing, strategic partnerships or other arrangements. Any additional equity, convertible debt or other equity-related securities that we issue could materially dilute the ownership interests of holders of our common stock and debt financing would require that we use a portion of our cash, which could be material, to fund debt service payments and also could require that we comply with financial and other covenants that limit our flexibility and operations or that we pledge assets, including intellectual property, to secure payment of the principal of and interest on borrowings. If we raise funds through collaborative or licensing arrangements we may be required to relinquish, on terms, that are not favorable to us, rights to some of our technologies or product candidates that we would otherwise seek to develop or commercialize ourselves, and we may be required to share any revenues generated by any of our product candidates that may receive regulatory approval and are successfully commercialized with our collaborators or licensing partners. In addition, our VAST small molecule drug discovery technology currently relies on partnerships with pharmaceutical and biotechnology companies and on collaborations with academic groups and in the past has relied and in the future may rely on government grants, if available, and if Alchemia Limited is unable to assign these collaboration agreements and grant arrangements to us as described below or if those partnerships or collaborations terminate or if we are unsuccessful in obtaining future grants, we may need to find alternative sources of funding to further our drug discovery initiatives. There is no guarantee that we would be successful in obtaining any such funding on terms that we deem acceptable, or at all. In addition, as described above under “Risk Factors — Alchemia Limited may be unable to transfer its rights under collaboration agreements and government grant arrangements relating to the VAST technology to us,” if Alchemia Limited is unable to obtain necessary consents to assign collaboration agreements and government grant arrangements relating to the VAST technology to us, it will deprive us of the support and, if applicable, any funding potentially available under those agreements and arrangements, which would increase our need for external financing. Our failure to raise capital when needed could have a material adverse impact on our research and development activities, results of operations, financial condition and business generally.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations as at March 31, 2012:


	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years
	(in thousands)
Obligations to Monash University	$	528	$	528	$	—	$	—	$	—
Total	$	528	$	528	$	—	$	—	$	—

We have a research and development agreement with Monash University whereby the University provides staff, consumables and infrastructure facilities to carry out the ongoing HyACT projects on their Clayton campus in Melbourne, Australia. The annual fee for use of these facilities for the calendar year 2012 is $704,431. This is an annually renewable contract and the annual fee is therefore renegotiated in connection with each renewal.

-87-

Our RD&CT agreement with Novozymes was superseded by two other agreements we entered into in July 2009. The first agreement is a supply agreement whereby we agree to use Novozymes as our exclusive supplier of HA for our HA-Irinotecan-based product and Novozymes agrees to supply us with HA and to use commercially reasonable endeavors to build and maintain sufficient manufacturing capacity to reliably supply us with HA, including the construction of a new HA production facility. Novozymes does not currently have the manufacturing capacity to supply HA in accordance with the agreement, and although the agreement provides that Novozymes use commercially reasonable endeavors to achieve such sufficient manufacturing capacity by no later than January 1, 2014, we cannot assure you that this will occur. Assuming that Novozymes is able to construct a manufacturing facility as contemplated by the agreement, the agreement calls for us to provide Novozymes with a rolling three year estimate of our annual need of HA. We are not obligated to forecast any minimum estimate. Upon acceptance of our forecast by Novozymes, we and Novozymes will each be obligated to purchase and supply, respectively, 100% of the total forecasted quantities for the first year based on an agreed scheme adjusted for price index changes. The forecast for the two remaining years are non-binding. Novozymes agrees that the price at which it supplies HA to us is to be the best price it offers to any of its customers for HA of a reasonably similar quality and volume. The supply agreement will remain in effect for the later of seven years from its commencement or five years after the date when Novozymes begins supplying us with HA. At the end of such term and any further term, the supply agreement will automatically extend for a further five years unless either party has given notice not to extend it.

In the related royalty agreement between us and Novozymes, for as long as the relevant product remains covered by a HyACT patent or we receive any royalties from a licensee of the product, we are committed to pay Novozymes a 1.0% royalty on the net sales from any HA-Irinotecan product and a 0.5% royalty on net sales of any other product containing HA developed under the HyACT patents, regardless of whether Novozymes is able to supply HA to us. If Novozymes is capable of supplying HA to our specifications and we do not use them as our supplier for HA, we have to pay a 2.0% royalty on our net sales from any HA-Irinotecan product and 1.0% royalty on our net sales of any other product containing HA, provided that royalty will be reduced to 1.0% for HA-Irinotecan product and 0.5% for any other products containing HA if Novozymes is the defaulting party under the supply agreement or if it fails to complete the new HA production facility contemplated in the supply agreement. In the event that we license any other product containing HA to a licensee and the royalty we receive from the licensee is less than 10.0% of the net sales of such product and development for such product has not commenced a Phase II trial at the time the license is entered into, the royalty payable to Novozymes under the royalty agreement will be 5.0% of the percentage of the net sales we receive. We must comply with the license agreement whether or not Novozymes is able to supply HA to us under the supply agreement. Subject to certain termination events, this agreement is valid until the expiry of our last HyACT patents, which, as of June 15, 2012, is in 2026.

We have a Clinical Research Services Agreement with PSI CRO AG, or PSI, an international clinical trial management company. Pursuant to this agreement, PSI is managing and coordinating the HA-Irinotecan Phase III clinical trial. The amount payable to PSI is milestone driven with a total estimated cost of approximately $8.9 million if those milestones are achieved, of which an amount of $2,572,396 had been paid as of March 31, 2012. In addition, we are obliged to reimburse PSI for out-of-pocket expenses and third party vendor costs. This contract is cancellable at any time at our sole discretion.

We have also entered into a general services agreement with BioClinica Inc, an international medical image management provider for clinical trials, to provide medical imaging services for the Phase III clinical trial. The overall project cost is estimated at approximately $1.4 million. This contract is cancellable at any time at our sole discretion.

Off-Balance Sheet Arrangements

As at the date of this filing, other than the issuance of the Rights noted below, we did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on the results of operations or our financial condition, including, and without limitation, such considerations as liquidity and capital resources.

-88-

Warrants

In November and December 2011, Alchemia Limited issued and sold its ordinary shares in a private placement, or the Placement, for total net proceeds of approximately AUD$16.1 million. Pursuant to the terms of the Placement, the investors were given rights, or the Rights, pursuant to which we are required, contingent on completion of this offering, to issue warrants, or the Warrants, to the investors entitling them to acquire shares of our common stock. The exercise price of the Warrants will be equal to 130% of the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price for such period as the Average Trading Price). The number of shares of our common stock, or the Warrant Shares, that will be issuable upon exercise of those Warrants will be equal to the quotient obtained by dividing (1) AUD$8,073,000 (equivalent to approximately US$8,066,542 based on the average of the currency exchange rates on November 11, 2011 and December 21, 2011, the dates on which the private placement closed) by (2) 130% of the Average Trading Price. Assuming an Average Trading Price of US$ per share (the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus) and an exchange rate of U.S. dollars for one Australian dollar, approximately Warrant Shares would be issuable upon exercise of the Warrants at an exercise price of approximately US$ per share. However, because the number of Warrant Shares and exercise price both depend upon the actual Average Trading Price following this offering and the number of Warrant Shares also depends upon the exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. See “Prospectus Summary — The Offering” for an analysis showing how changes in the Average Trading Price change the number of Warrant Shares issuable upon exercise of the Warrants and the exercise price of the Warrants and how changes in the currency exchange rate affect the number of Warrant Shares issuable upon such exercise. In addition, the number of Warrant Shares and/or the exercise price are subject to adjustment pursuant to the terms of the Warrants, including in the event of stock splits, stock combinations and similar events as well as in the event of dividends or other distributions on our shares of common stock.

The Warrants will vest and be exercisable from the date that is six months after the date of this offering, or the IPO Date, until the date that is the later to occur of the following, or the Expiry Date:

•

three years from the IPO Date; and

•

the earlier of (A) six months from the date that we announce to the market the results for the primary endpoint of the Phase III clinical trial period for HA-Irinotecan in colorectal cancer and (B) five years from the IPO Date.

Any Warrant that is not exercised prior to the Expiry Date will automatically expire on the Expiry Date.

The Rights are a liability classified under ASC 480, “Distinguishing Liabilities from Equity” as (i) the ordinary shares issued by Alchemia Limited in the Placement and the Rights are legally detachable instruments (meaning that there is no requirement that they be transferred as a unit) and (ii) the Rights can only be settled with a variable number of our shares of common stock with a fixed monetary amount of approximately AUD$8.1 million. Accordingly, such Rights are recorded as a pushdown liability incurred by us, given the obligation to issue such Warrants to purchase shares of our common stock. Such Rights were initially recognized at fair value on the date of issuance and are remeasured at the end of each reporting period with an adjustment to fair value recorded to the results of operations. The initial fair value of these Rights has been determined to be insignificant, as the issuances of the Warrants pursuant to the Rights are contingent on this offering, which is not within our control.

Quantitative and Qualitative Disclosures about Market Risk

Our exposure to market risk is confined to our cash and cash equivalents which have maturities of three months or less. The primary objective of our investment activities is to preserve our capital to fund operations. We also seek to increase income from our investments without assuming significant risk. Historically we have not held any significant cash or cash equivalent or short-term deposit amounts but with approximately

-89-

$7.5 million of additional cash loaned to us by Alchemia Limited on June 28, 2012 (which loan was cancelled as described above under “—Financial Operations Overview—Loan Conversion”) and the net proceeds we receive from this offering, the amount we hold in cash, cash equivalents and short-term deposit will increase. We intend to invest the net proceeds from this offering in interest bearing and similar investments with terms of 18 months or less, which may include interest-bearing bank accounts, money market funds, certificates of deposit and government securities.

As our functional currency is the Australian dollar, we are exposed to foreign exchange risk, mainly with the U.S. dollar which is the currency in which we are invoiced by most of our contract research organizations for the costs of conducting our clinical trials. Our policy is to minimize the use of financial derivatives and we endeavor to achieve risk mitigation through natural hedges. These natural hedges may include the maintenance of a U.S. dollar bank account and bank accounts in any other currency that we may have significant exposure in the future to facilitate the settlement of invoices in these currencies.

Emerging Growth Company Status

Section 107 of the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933 for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we are choosing to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2011-04, “Fair Value Measurement (Topic 820),” Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”) ASU 2011-04 amends the fair value measurement and disclosure guidance in ASC 820, “Fair Value Measurement,” to converge U.S. GAAP and International Financial Reporting Standards requirements for measuring amounts at fair value as well as disclosures about these measurements. The amendments are effective during interim and annual periods beginning after December 15, 2011. We do not expect that the adoption of ASU 2011-04 will have a material impact to our consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05 (ASU 2011-05), “Presentation of Comprehensive Income”. ASU 2011-05 requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. In December 2011, the FASB issued ASU 2011- 12 (ASU 2011-12), “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 defers the requirement in ASU 2011-05 that entities present reclassification adjustments for each component of accumulated other comprehensive income, or AOCI, in both net income and other comprehensive income on the face of the financial statements. ASU 2011-12 requires entities to continue to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. The effective date of ASU 2011-12 is consistent with ASU 2011-05, which is effective for fiscal years and interim periods beginning after December 15, 2011 for public entities. We do not expect that the adoption of both ASU 2011-05 and ASU 2011-12 will have a material impact to the presentation of our consolidated financial statements.

BUSINESS

Overview

We are a late stage biopharmaceutical company primarily focused on utilizing our Hyaluronic Acid Chemotransport Technology, or HyACT, to target cancer drugs preferentially to tumor cells to enhance drug activity. HyACT is a flexible platform technology designed to increase the effectiveness of anti-cancer agents without increasing treatment toxicity. We seek to reduce the risks related to drug development by using known anti-cancer drugs, and aim to enhance their commercial value by improving their effectiveness. Our lead HyACT product candidate, HA-Irinotecan, is currently in a pivotal Phase III clinical trial for metastatic colorectal cancer, or mCRC. HA-Irinotecan is also in an investigator-sponsored Phase II clinical trial for small cell lung cancer, or SCLC. We also have two other HyACT product candidates that have successfully completed Phase I clinical trials. In addition to our current clinical-stage product candidates, we aim to develop a pipeline of product candidates by exploiting our significant know-how in cancer stem cell biology and cancer metabolism combined with the Versatile Assembly on Stable Templates, or VAST, molecule drug discovery technology that we will in-license.

Our lead product candidate is HyACT-targeted irinotecan, or HA-Irinotecan, for the treatment of mCRC. Irinotecan, which is marketed in major markets by Pfizer as Camptosar, is an off-patent chemotherapy drug widely used in the treatment of mCRC. In a 76 patient, randomized Phase II clinical trial of HA-Irinotecan compared with irinotecan alone, HA-Irinotecan was able to double the time it took for patients’ tumors to grow (also known as progression free survival, or PFS) in mCRC patients. After having consultations with the U.S. Food and Drug Administration, or FDA, we commenced a pivotal Phase III clinical trial testing HA-Irinotecan in patients with mCRC in November 2011. This trial is designed to recruit 390 irinotecan-naïve, second and third line patients and will directly compare HA-Irinotecan with irinotecan alone, in both cases as components of the FOLFIRI chemotherapy regimen (leucovorin, 5-fluorouracil and irinotecan). The primary endpoint for the trial is PFS, and if the trial is successful, we intend to seek regulatory approval from both the FDA (using the 505(b)(2) regulatory approval pathway) and the European Medicines Agency, or EMA, of HA-Irinotecan for the treatment of mCRC in the United States and the European Union. In addition, a Phase II clinical trial of HA-Irinotecan in SCLC started recruitment in September 2011. This investigator-sponsored trial will examine the clinical benefits of HA-Irinotecan compared with irinotecan alone, as well as the direct effect of HA-Irinotecan on cancer stem cells and other aggressive cancer cell populations through analysis of tumor biopsies. The objective of this Phase II trial is to demonstrate that, by targeting the CD44 receptor on cancer stem cells, HA-Irinotecan may enhance the killing of the cancer stem cell and cancer cell populations, which may ultimately translate into increased patient survival. We are participating in this investigator-sponsored trial primarily because of the potential to

-91-

further validate the HyACT technology and the data on HA-Irinotecan’s activity on cancer stem cells that it may provide. We currently do not intend to pursue further clinical trials or commercialization of HA-Irinotecan for the treatment of SCLC and, accordingly, references to our “product candidates” do not include HA-Irinotecan for the treatment of SCLC.

Despite the considerable research and development efforts of the pharmaceutical industry, cancer remains a significant unmet medical need. Chemotherapeutics remain the backbone of many drug-based anti-cancer treatment regimens. Due to the non-specific nature of current chemotherapeutics, they are typically administered at the maximum tolerated dose, not at the optimal dose required to kill the cancer. As evidenced by the current recurrence and mortality rates associated with cancers, there remains a need to identify new and more effective anti-cancer treatments.

We have considerable know-how, research and preclinical expertise in HA, cancer metabolism, CD44 and cancer stem cells. Prior to the closing of this offering, we will in-license rights to Alchemia Limited’s Versatile Assembly on Stable Templates, or VAST, small molecule drug discovery technology, which provides innovative pyranose compounds for drug discovery. Our strategy is to use these capabilities to investigate new pathways relating to CD44 signaling, HA metabolism and pro-oncogenic pathways that we believe are important to the promotion and proliferation of cancer stem cells. We aim to generate future drugs designed to more effectively target and kill cancer and cancer stem cells.

Our Strategy

•

Leveraging our proprietary HyACT technology to bring improved anti-cancer agents to market. Our objective is to use our HyACT technology to improve the delivery of chemotherapeutic agents to

-92-

cancer cells, boosting drug efficacy without increasing side-effects, thereby increasing the therapeutic index of current chemotherapeutics. We intend to utilize the FDA 505(b)(2) regulatory pathway, which may offer a lower development risk profile and accelerated development compared with completely new cancer drugs.

•

Successfully developing our lead product candidate, HA-Irinotecan, for the treatment of metastatic colorectal cancer. After having consultations with the FDA, we began recruiting patients for a pivotal Phase III clinical trial testing HA-Irinotecan in patients with mCRC in November 2011. If this clinical trial is successful, we intend to seek regulatory approval from both the FDA and the EMA of HA-Irinotecan for the treatment of second and third line mCRC patients in the United States and the European Union.

Our Technologies

HyACT

HyACT as a Drug Delivery Vehicle

HA’s physiochemical structure allows it to form a “meshwork” well-suited for entrapping smaller molecules and proteins such as chemotherapeutic agents and monoclonal antibodies. Specifically, in aqueous solution, the linear, unbranched HA polymer exhibits a tertiary coiled structure that allows multiple hydrogen bonds to form between adjacent saccharides. The dynamic nature of these multiple hydrogen bonds creates a stiffened but flexible polymer with a large hydrodynamic domain sufficient to entrap a number of drugs.

-93-

HyACT as a Tumor Targeting Agent

HyACT has a high avidity for the activated form of its native receptor, CD44. Upon binding to CD44, HyACT-targeted drugs are readily internalized into the tumor cell. CD44 is a broadly distributed transmembrane glycoprotein that plays a key role in the behavior of malignant cells, including adhesion, migration, invasion, and survival. In its activated, high-affinity state, CD44 is capable of binding to HA. In contrast to normal cells, tumor-derived cells predominantly express activated CD44. HyACT-targeted drugs bind to activated CD44, which triggers internalization of the anti-cancer drug into the cell, resulting in increased intracellular drug concentrations that we believe may translate into superior efficacy. Preclinical biodistribution studies have demonstrated that within 30 minutes after intravenous injection, HA is internalized within the microvasculature of the tumor. This has been shown in preclinical studies to result in up to 400% more drug in the tumor and lymph nodes for HyACT-targeted anti-cancer drugs compared with the same anti-cancer drugs administered alone. The following table, which reflects data that we obtained from various published sources, shows the approximate percentage of activated CD44 receptors found in certain types of healthy and malignant tissue:


	Approximate Percentage of Activated CD44 Receptors
Cancer Type	Healthy Tissue	Diseased Tissue
Bladder	0%	100%
Breast	0%	50-100%
Colorectal	0%	70-80%
Endometrial	0%	50-80%
Malignant mesothelioma	0%	100%
Ovarian	0%	100%
Pancreatic	0%	70-100%
Prostate	0%	60-80%
Renal	0%	50%

Based on preclinical studies, we believe that some of the key characteristics of HyACT include (i) HyACT’s drug entrapment properties, (ii) HyACT’s ability to carry anti-cancer drugs to the tumor, (iii) HyACT’s formation of cancer-localized drug depots, and (iv) the internalization of HA in an active CD44 receptor-based mechanism. The result is that HyACT-targeted drugs are maintained in the tumor environment for longer with enhanced uptake by the cancer cells through activated CD44. In addition, we have seen no significant increase in toxicity in our preclinical studies and clinical trials of HyACT-targeted drugs compared with the drugs alone.

The figure below depicts the HyACT mechanism of action, from the bloodstream into a cancer cell, based on preclinical testing:

HyACT Mechanism of Action

LOGO



		HyACT-targeted drug delivery vehicle with entrapped anti-cancer drug in the bloodstream after infusion
		HyACT-targeted drug accesses the tumor environment through leaky vasculature typical of vessels that supply blood to tumors. HyACT-targeted drugs form a drug depot in the extracellular space of the tumor
		HyACT-targeted drug binds to activated CD44 and then is rapidly internalized, resulting in more drug entering the tumor cell
		HyACT-targeted drug is transported into an intracellular vesicle and the hyaluronic acid is degraded
		HyACT-targeted drug is released within the cancer cell, increasing the likelihood of cell death and enhanced tumor response
		HyACT-targeted drug depot generally persists for at least 24 hours, resulting in repeated cycles of drug internalization and release inside tumor cells

The figure above is based on preclinical data and the clinical significance is unknown.

HyACT and Cancer Stem Cells

“Cancer stem cells,” sometimes referred to as tumor-initiating cells, is a term used to describe a small subset of cells within the tumor that, although not actual stem cells, demonstrate stem cell-like characteristics, such as self-renewal and the ability to form multiple lineages. Cancer stem cells have been identified in many types of cancer, including colon, breast, pancreatic, brain, lung and leukemia. Following cancer treatment, the residual tumor mass can still contain a high percentage of cancer stem cells, which are generally resistant to further treatment. In addition, patients who relapse can develop metastatic disease in which the cancer spreads to other sites in the body. Scientific literature suggests that the expression of high levels of CD44 is a distinguishing feature of the more resistant and aggressive cancer cell populations, including cancer stem cells.

Although there is no universal cancer stem cell marker, we believe that CD44, CD133, EpCAM and aldehyde dehydrogenase, or ALDH, are generally accepted as some of the better phenotypic markers of cancer stem cells. The consistent identification of CD44 on cancer stem cells led us to investigate whether the HyACT-targeted technology also preferentially bound to cancer stem cells, delivering increased concentrations of chemotherapy into those cells. Preclinical investigations in colon and breast cancer stem cells demonstrated the anti-cancer properties of HyACT-targeted irinotecan, HyACT-targeted doxorubicin and HyACT-targeted gemcitabine on cancer stem cells. This can be seen in the following photographs, which show the punctuate fluorescence (indicated by the arrow on the left-hand bottom panel) associated with the increased intracellular uptake of doxorubicin and HA-doxorubicin in breast cancer stem cells with activated CD44 as well as in other breast cancer cells with and without activated CD44 (referred to as activated CD44 positive and activated CD44 negative, respectively, in the captions above these photographs):

VAST

We will in-license worldwide rights to the VAST technology from our parent, Alchemia Limited. This technology is designed to enable the discovery of new, small molecule drugs through the use of molecular “probes.” The VAST technology is based on high throughput, synthetic chemistry on pyranose scaffolds and comprises an array of compounds, which due to their rigidity and high chirality (compound shape), can enable the systematic exploration of new drugs. In 2009, we completed the synthesis of a diversity scanning array, or DSA, a suite of approximately 14,000 pyranose-based compounds that systematically arrange typical binding groups in a broad range of possible three-dimensional orientations. This array has the ability to identify the shape and functional requirements of molecules that modulate a target.

HA-Irinotecan

Overview

Our lead product candidate is HA-Irinotecan for the treatment of metastatic colorectal cancer, or mCRC. Irinotecan, which is marketed in major markets by Pfizer as Camptosar, is an off-patent chemotherapy widely used in the treatment of mCRC. In a randomized Phase II clinical trial of HA-Irinotecan compared with irinotecan alone, based on 76 patients with mCRC, HA-Irinotecan was able to double the progression free survival, or PFS, in mCRC patients (5.2 months for HA-Irinotecan versus 2.4 months for irinotecan alone). Based on these findings, we began enrollment for a pivotal Phase III clinical trial, testing HA-Irinotecan in patients with mCRC in November 2011.

Metastatic Colorectal Cancer Market

According to the American Cancer Society, colorectal cancer is the third most common form of cancer diagnosed in the United States, excluding skin cancers. According to the American Cancer Society, approximately 143,000 new cases of colorectal cancer are expected to be reported in the United States in 2012, with approximately 51,000 patients in the United States expected to die from colorectal cancer in 2012. Surgery is often the first line treatment for early stage colorectal cancer. When colorectal cancer metastasizes (spreads to other parts of the body such as the liver), chemotherapy is commonly used. Chemotherapy regimens (i.e., FOLFOX (leucovorin, 5-fluorouracil and oxaliplatin) or FOLFIRI (leucovorin, 5-fluorouracil and irinotecan), either with or without bevacizumab) have been shown to increase survival rates in patients with metastatic/advanced colorectal cancer and are among the leading first and second line treatments in the United States and Europe. Currently, there are seven FDA approved drugs for patients with mCRC: 5-fluorouracil, bevacizumab (Avastin), capecitabine (Xeloda), cetuximab (Erbitux), irinotecan, oxaliplatin and panitumumab (Vectibix). Depending on the stage of the cancer, two or more of these drugs may be combined at the same time or used after one another. Bevacizumab, a vascular endothelial growth factor, or VEGF, monoclonal antibody, is commonly administered with chemotherapy. Typically, patients who fail 5-fluorouracil, oxaliplatin, irinotecan, and bevacizumab-containing therapies, and who have wild-type KRAS status, receive epidermal growth factor receptor, or EGFR, monoclonal antibody therapy with either cetuximab or panitumumab, together with chemotherapy. We believe that if approved, HA-Irinotecan could replace irinotecan currently in use in the FOLFIRI treatment regimen.

HA-Irinotecan Preclinical Results

In preclinical studies on human cancer xenografts, we demonstrated a significant increase in the concentration of HA-Irinotecan within tumor cells compared with irinotecan alone. The following figure shows HA-Irinotecan versus irinotecan uptake in human colorectal cancer xenografts in one of those studies;

As seen in the figures below, our subsequent preclinical studies on human colorectal cancer xenografts showed HA-Irinotecan reduced the size of tumor xenografts when compared with irinotecan alone in irinotecan-resistant and irinotecan-sensitive tumors, providing our first indication of the potential efficacy improvements in tumor shrinkage by HA-Irinotecan:

HA-Irinotecan Clinical Development

In our completed Phase I and Phase II clinical trials, we have tested HA-Irinotecan in 88 patients, demonstrating no significant increase in toxicity or plasma pharmacokinetic characteristics, with significant improvements in certain measures of efficacy versus irinotecan alone in the Phase II clinical trial.

Phase I Clinical Trial for Metastatic Colorectal Cancer

In our open-label Phase I dose escalating trial, we tested 12 patients who had previously failed treatment with 5-flourouracil. Patients were given an initial dose of HA-Irinotecan containing 300 mg/m² irinotecan, followed by dose escalation to 350 mg/m² irinotecan, where these therapies were administered on a 21 day cycle. In this trial, 17% of patients showed an overall response (comprised of both partial and complete responders) and 50% of patients demonstrated stable disease. There was no evidence of increased toxicity, such as grade 3 or grade 4 diarrhea, vomiting and neutropenia, compared with historic studies of single agent irinotecan when administered under the same schedule. We achieved our primary objective of demonstrating safety and tolerability of HA-Irinotecan in this Phase I trial.

Randomized Phase II Clinical Trial for Metastatic Colorectal Cancer

The Phase II clinical trial was conducted at 10 clinical trial sites in Australia. This randomized study tested HA-Irinotecan versus irinotecan alone in 76 patients who had previously failed treatment for mCRC with a 5-fluorouracil-containing regimen. Patients were randomized to receive up to eight cycles of treatment with either irinotecan alone or HA-Irinotecan, each containing 350 mg/m² irinotecan administered every 21 days.

While we did not achieve the primary endpoint of a reduction in diarrhea in our Phase II clinical trial, we did observe statistically significant improvements in progression free survival, or PFS, and other efficacy endpoints for HA-Irinotecan compared with irinotecan alone. Key data from this Phase II clinical trial showed:

•

patients receiving HA-Irinotecan experienced statistically significant increases in the period of PFS (5.2 months versus 2.4 months, + 116%; p=0.017), with a hazard ratio of 0.46 (p=0.011) after adjustment for 13 prognostic factors;

•

patients receiving HA-Irinotecan experienced a significantly longer time to treatment failure, or TTF (4.0 months versus 1.8 months, + 122%; p=0.007);

•

patients receiving HA-Irinotecan experienced a trend where overall survival, or OS, increased by about two months (10.1 versus 8.0 months; p=0.196), with a hazard ratio of 0.75 (p=0.376) after adjustment for 13 prognostic factors;

•

HA-Irinotecan exhibited a superior anti-cancer effect, with more patients experiencing anti-tumor responses or stable disease, with a final disease control rate of 76% in the HA-Irinotecan arm of the trial versus 46% in the irinotecan-alone arm (p=0.053);

•

HA-Irinotecan patients were able to be treated for significantly more cycles: the median number of completed cycles was six compared with two for irinotecan alone patients (p = 0.005). Within the study cohort, the total number of cycles administered was 213 for HA-Irinotecan-treated patients compared with 123 for irinotecan alone patients;

•

14 (34%) HA-Irinotecan-treated patients and five (14%) irinotecan-alone-treated patients completed eight treatment cycles (p = 0.062);

•

dose intensity per cycle was almost identical for both treatment arms, with the total cumulative dose being attributable to the delay in tumor progression (median 2.50 times higher for HA-Irinotecan; mean 1.46 times higher for HA-Irinotecan); and

•

no significant change in safety and no significant increase in toxicity were observed; a similar frequency and spectrum of toxicity were observed in both arms of the clinical trial.

On-Going, Randomized, Double-Blind Phase III Clinical Trial of HA-Irinotecan in 2nd/3rd Line Metastatic Colorectal Cancer

After having consultations with the FDA, we commenced our pivotal Phase III clinical trial of HA-Irinotecan for the treatment of mCRC. Our pivotal Phase III clinical trial is comparing the effectiveness of HA-Irinotecan with irinotecan, in each case as components of the FOLFIRI chemotherapy regimen (leucovorin, 5-fluorouracil and irinotecan), in 390 irinotecan-naïve, second and third-line patients with mCRC. We believe that the FOLFIRI regimen is generally considered the leading standard of care for second and third line treatment for mCRC in the United States and Europe. The primary objective of this study is to demonstrate that HA-Irinotecan provides superior efficacy compared with irinotecan alone, as indicated by a significantly increased period of PFS.

The randomized, multi-centered, double-blind trial is designed to detect a six week or greater difference in PFS (primary endpoint is PFS, 85% power) with monitoring for up to 18 months following randomization. HA-Irinotecan is being used as an absolute replacement for irinotecan alone within the FOLFIRI regimen, where it is used at the same dose and administered in a substantially identical manner to that currently used for irinotecan in the clinic. Recruitment commenced in November 2011 and the trial is being conducted at sites in Australia, Bulgaria, Russia, Poland, Serbia, Ukraine and the United Kingdom. Trial sites were selected on the basis of, among other factors, the availability of patients, quality of patient management and experience in data handling and clinical trials. PSI, our contracted research organization for this trial, is an international clinical research company that conducts its business in North and South America, Asia, Australia, Europe and Russia. According to PSI, oncology is the largest therapeutic area in which it works and over the past 15 years, it has run over 150 oncology studies. Also according to PSI, the following drugs were approved by the FDA and/or EMA with pivotal data coming from PSI: Abraxane, Halaven, Femara, Firmagon, Thalomid, Aloxi, Zarzio and Neulasta.

In addition to the primary endpoint of PFS, we are conducting a small sub-study looking at QTc prolongation and the pharmacokinetics of HA-Irinotecan within the FOLFIRI regimen. If this clinical trial is successful, we intend to seek regulatory approval from both the FDA and the EMA for HA-Irinotecan for mCRC in the United States and the European Union, although we cannot assure you that this will occur. See “Risk Factor — We are highly dependent on the success of our lead product candidate, the cancer drug HA-Irinotecan for the treatment of metastatic colorectal cancer, and we cannot give any assurance that we will successfully complete its clinical development, or that it will receive regulatory approval, or if approved, that it will receive adequate labeling that will allow for successful commercialization for the treatment of mCRC” and “— Regulatory Strategy” below.

Because of the difficulty in reliably determining cancer progression based on imaging studies in cancer, the FDA’s policy is to recommend that the primary endpoint for a cancer registration trial be overall survival, or OS, whereas our Phase III clinical trial has PFS as its primary endpoint. However, certain drugs have been approved by the FDA based on primary endpoints other than OS, including Erbitux for mCRC and Abraxane for metastatic breast cancer. As our trial has PFS as its primary endpoint, it is essential that the tumor responses are stringently monitored to enable the FDA and EMA to accurately determine the efficacy of HA-Irinotecan versus irinotecan alone. We believe that we have developed a rigorous protocol designed to produce consistent tumor measurements. The process we designed and adopted involves tumor scans being independently analyzed by separate onsite and offsite evaluations. Each evaluation of a scan occurs in a double blinded fashion, with none of the physician, the patient or the radiologist knowing which treatment the patient is receiving. Each patient has a tumor scan prior to commencing treatment. Then, commencing six weeks after the first treatment and generally every six weeks thereafter, patients present themselves at a medical facility for tumor scans. An onsite evaluation of the scan is then performed by the lead investigator or a radiologist who is experienced in using the Response

-101-

Evaluation Criteria in Solid Tumors version 1.1, or RECIST, criteria. In the event that the evaluator believes that a tumor scan documents progressive disease based on the RECIST criteria, a second onsite evaluator (either the lead investigator or a radiologist) must concur in the evaluation. In the event of a disagreement between the two onsite evaluators, the patient must continue as part of the trial and on trial chemotherapy as tolerated until the next scheduled tumor assessment. These onsite evaluations are performed for patient management purposes in order to determine whether the patient should continue as part of the trial. The blinded tumor scans are subsequently sent to BioClinica, an international medical image management provider for clinical trials, for offsite evaluation. BioClinica reviews each scan and applies the RECIST criteria. Two BioClinica-contracted radiologists must independently arrive at the same conclusion on a patient’s tumor response for that response to be confirmed; otherwise a third BioClinica-contracted radiologist is brought into the assessment process to make the decision regarding when the patient progressed. The BioClinica assessment (and not the onsite evaluation) is used in the analysis of results from the trial. In addition, we have engaged an independent statistical team, Pharmanet (USA), to verify, approximately every four weeks, that the onsite interpretation of the data from the scans concurs with Pharmanet (USA)’s assessment according to the RECIST criteria.

The primary endpoint will be reached when 350 patients have died or experienced disease progression. We have secured an independent Data Safety and Monitoring Board, or DSMB, which, as of May 22, 2012, had assessed data from the initial 39 patients and found no unexpected toxicities and therefore approved the continuation of the trial.

Regulatory Strategy

As HA-Irinotecan is a formulation of two previously approved products (the cancer drug irinotecan and HA), we intend to utilize an alternative type of New Drug Application, or NDA, commonly referred to as a Section 505(b)(2) NDA, which enables us to rely, in part, on the FDA’s previous approval of a similar product, or on published literature, in support of our application. Irinotecan was developed and marketed by Pfizer as Camptosar, while HA formulations have been approved by the FDA for use in ocular surgery, dermal fillers and cosmetics. The 505(b)(2) regulatory approach may enable us to produce an abbreviated preclinical data package, thereby saving development time and costs.

A fixed dose combination product is one in which two or more separate drug ingredients are combined in a single dosage form. In order for a fixed dose combination product to be approved by the FDA, the applicant must demonstrate that each drug makes a contribution to the claimed effects of the combination, and that the dosage of each drug is such that the combination is safe and effective for a significant patient population requiring concurrent therapy with the drugs. One example of a fixed dose combination product is where one drug is combined with another drug in order to enhance the second drug’s safety or effectiveness. The FDA views our HA-Irinotecan product candidate, and may also view each of our other HyACT-containing product candidates, as such a combination and has indicated that we must demonstrate through a clinical trial that HyACT contributes to the efficacy and/or safety of the combination.

After having consultations with the FDA, we commenced our pivotal Phase III clinical trial of HA-Irinotecan for mCRC. If this pivotal trial is successful, we intend to seek regulatory approval from both the FDA and the EMA of HA-Irinotecan for the treatment of mCRC in the United States and the European Union. However, even if our pivotal Phase III trial meets its PFS primary endpoint, an additional trial regarding OS could be required as either a pre-approval requirement or as a post-marketing commitment should approval be granted based on PFS. If the FDA were to require a second Phase III clinical trial as a pre-approval requirement, it would substantially increase the time and cost of our development activities and, in any event, may not ultimately result in regulatory approval. In addition, if the FDA approves HA-Irinotecan for mCRC based on meeting our PFS primary endpoint but requires post-marketing clinical trials or analyses, the approval could be withdrawn if any required post-marketing trials or analyses do not meet FDA requirements. Moreover, even if HA-Irinotecan receives regulatory approval, such approval may not allow us to charge a premium over a generic version of irinotecan; if that were to occur, we may not be able to successfully commercialize this product, which

-102-

could have a material adverse effect on our business. See “Risk Factors — We are highly dependent on the success of our lead product candidate, the cancer drug HA-Irinotecan for the treatment of mCRC, and we cannot give any assurance that we will successfully complete its clinical development, or that it will receive regulatory approval, or if approved, that it will receive adequate labeling that will allow for successful commercialization for the treatment of mCRC.” and “Business — Government Regulations.”

Investigator-Sponsored Phase II Trial of Small Cell Lung Cancer

In September 2011, recruitment began for an investigator-sponsored Phase II clinical trial of HA-Irinotecan in small cell lung cancer, or SCLC. Patients will be randomized to receive either HA-Irinotecan or irinotecan, each in combination with carboplatin. The parameters that will be assessed include safety and measures of efficacy such as PFS. This investigator-sponsored trial has been initiated under the Clinical Trials Notification Scheme, or CTN, of Australia. Approximately 40 first line patients are to be recruited to the trial, which is being conducted at Monash Cancer Centre, Southern Health and Peninsula Oncology Centre in Melbourne, Australia. The primary endpoints for this trial are an efficacy endpoint of the proportion of cancer stem cells remaining after therapy and a safety endpoint of the incidence of grade 3 and 4 toxicity. In addition to these safety and efficacy endpoints, the Phase II clinical trial will measure the additional efficacy endpoints of PFS at six months, objective response rate, survival and the impact of the treatments on circulating tumor cells (the number of cancer cells detected in the blood), an indication of disease progression and prognosis. We are participating in this investigator-sponsored trial primarily because of the potential to further validate the HyACT technology as well as to obtain clinical data on cancer stem cells. As this is an investigator-sponsored trial, our involvement in the trial has been limited. We currently do not intend to pursue further clinical trials or commercialization of HA-Irinotecan for the treatment of SCLC and, accordingly, references to our “product candidates” do not include HA-Irinotecan for the treatment of SCLC.

Preclinical studies have demonstrated that HA-Irinotecan, either in combination with other chemotherapeutics or alone, can target and kill the SCLC stem cells, which are believed to often contribute to recurring disease and ultimately death of the patient; therefore, if the preclinical findings translate into the clinical setting, it is possible that durable clinical responses may be observed. If this trial provides clinical data demonstrating that HA-Irinotecan is more effective at removing cancer stem cells than irinotecan alone, this finding could support our research on mode of action and could significantly expand the types of cancers where HyACT may provide a superior benefit.

Other HyACT Programs

We used HyACT-targeted 5-fluorouracil in a Phase I / IIa clinical trial in 13 patients with mCRC. Nine patients received HyACT-targeted 5-fluorouracil, with three of these patients recording stable disease. Another five patients received leucovorin and HyACT-targeted 5-fluorouracil, with two patients recording stable disease. In this study, no unexpected toxicity was observed, suggesting an ability to safely combine HA with a clinically active dose of 5-fluorouracil.

We used HyACT-targeted doxorubicin in a Phase I / IIa clinical trial in 16 patients with metastatic cancer with a life expectancy of at least 12 weeks. Four of 16 patients treated with HA-doxorubicin had a partial tumor response, while another three recorded stable disease. In the trial, no unexpected toxicity was observed, suggesting an ability to safely combine HA with a clinically active dose of doxorubicin.

Preclinical Programs

We have also conducted preclinical studies that have suggested that HyACT has the potential for improving the efficacy of a number of other cancer drugs including gemcitabine (Gemzar), methotrexate (Rheumatrex), carboplatin (Paraplatin) and vinorelbine tartrate (Navelbine). We have also tested in preclinical studies a number of monoclonal antibodies, including bevacizumab (Avastin) and cetuximab (Erbitux), and are investigating the potential of running a parallel clinical trial comparing an HA-monoclonal antibody with the monoclonal antibody alone.

The following charts provide additional details of some of the preclinical work we have conducted so far, suggesting the efficacy of various HyACT-targeted anti-cancer drugs compared with the anti-cancer drugs alone, including doxorubicin, methotrexate, 5-fluorouracil, gemcitabine, irinotecan and cetuximab:

VAST Drug Discovery Technology

In addition to the HyACT platform, prior to the closing of this offering, we will in-license worldwide rights to the VAST small molecule drug discovery technology, which will give us the ability to research and develop new anti-cancer drug candidates. This technology has been deployed in several collaborations with pharmaceutical companies and research institutes exploring its capability and application in non-cancer therapeutic areas. These collaborations are exploiting the chemistry and molecular diversity offered by the VAST technology and diversity scanning array, or DSA, by addressing known targets in an innovative way. We plan to initiate programs to study inflammation pathways associated with cancer stem cells and cancer metabolism with a target involved in HA synthesis. These programs are intended to make use of the selectivity and compound efficiency of the VAST technology. Our VAST programs are run on a business model designed to limit our cash expenditures through the use of partnerships and, if and when available, government grants. These programs include the allosteric modulation of family B G-protein coupled receptors for chronic obstructive pulmonary disease and type II diabetes, as well as opioid receptor agonists and ion channel inhibitors for pain. The collaboration agreements referred to above that are currently in effect are between Alchemia Limited and various collaborators, and any arrangements for government grants relating to the VAST technology are also between Alchemia Limited and the Australian government. We are not a party to any of these collaboration agreements or government grant arrangements, and Alchemia Limited may be required to obtain the consent of its collaborators and the Australian government in order to transfer these collaboration agreements and government grant arrangements to us. If these consents are not granted, it may have a material adverse effect on our ability to exploit the VAST technology. See “Risk Factors — Alchemia Limited may be unable to transfer its rights under collaboration agreements and government grant arrangements relating to the VAST technology to us.”

We aim to partner with pharmaceutical and biotechnology companies in areas outside of oncology to validate and commercialize various programs employing the VAST technology in new drug development while progressing certain projects internally. However, the terms of our license agreement with Alchemia Limited provide that we may not sub-license this technology without Alchemia Limited’s consent, not to be unreasonably withheld. This limitation on sub-licensing may prevent us from entering into collaborations or similar arrangements or otherwise commercializing VAST technology.

Competition

Many of our competitors have significantly greater financial and other resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. It is possible that competitors may develop new products in our target market before we are able to develop such products. There are a number of companies carrying out some form of competitive activities. Competitive activities could include developing reformulations of irinotecan and other anti-cancer drugs for use in oncology applications, exploiting HA as a therapeutic, researching and developing product candidates from applied research on cancer stem cells, and conducting late stage clinical development for application in colorectal cancer. Our lead product candidate is HA-Irinotecan for the treatment

-105-

of metastatic colorectal cancer, or mCRC, and the following table shows potential competitors with drugs in late stage clinical development for mCRC as of June 28, 2012:


Company	Drug Name	Stage of Development
Bayer-Schering	regorafenib	Filed
Sanofi/Regeneron	aflibercept	Filed
Light Sciences Oncology	talaporfin sodium	Phase III
Nektar Therapeutics	PEG-irinotecan	Phase II

We are aware of a potential competitor, Nektar Therapeutics, or Nektar, which is developing a suite of new chemical entities with modified pharmacokinetic profiles through the pegylation of known therapeutic agents. For instance, Nektar’s product candidate is a pegylated version of irinotecan that is being assessed in a variety of cancers, including a Phase III clinical trial in metastatic breast cancer and two Phase II clinical trials in metastatic colorectal cancer and platinum resistant ovarian cancer. In addition, Merrimack Pharmaceuticals, Inc., or Merrimack, is developing a new formulation of irinotecan for application in pancreatic cancer. Having completed a Phase II clinical trial in May 2011, Merrimack recently initiated a Phase III trial for the same indication. Merrimack also has a Phase II trial and two Phase I trials in oncology indications ongoing. Companies working on cancer stem cells include Boston Biomedical, Inc. (acquired by Dainippon Sumitomo Pharma Co., Ltd.), OncoMed Pharmaceuticals, Inc., Stemline Therapeutics, Inc. and Verastem, Inc.

The VAST technology is a chemistry platform with competition anticipated from other drug discovery companies with novel chemistries. For instance, we are aware of companies, including Ensemble Therapeutics, Summit PLC and Tranzyme Pharma, that all have innovative chemistry platforms. Summit PLC has a small carbohydrate library based on imino sugar scaffolds which offer unique activities predominantly in carbohydrate modification pathways. Ensemble Therapeutics and Tranzyme Pharma use macrocyclic technology to position functionality on larger molecules accessing new chemical space between small molecules, such as VAST compounds, and biologics, such as antibodies. Other competitors include companies with an interest in cancer stem cells, mentioned above, and other HA-based companies.

For additional information on competition that we currently face and may face in the future, see “Risk Factors — If our competitors develop and market products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted. In addition, all of our current product candidates are combinations of HA and existing cancer drugs and will likely face continued competition from those existing drugs used alone and in alternative treatment regimens.”

VAST License Agreement

In connection with the Demerger, our Australian subsidiary, Audeo Discovery Pty Limited, will enter into a Technology License Agreement with Alchemia Limited. The license agreement will provide us with a non-transferable, worldwide license to use Alchemia Limited’s VAST technology, including related patents, patent applications and know-how. The license will be exclusive except in relation to one family of patents in respect of which there is an existing non-exclusive third party license. Under the Technology License Agreement, we will be subject to development obligations, reporting obligations, sublicense revenue sharing requirements, royalty payments and other obligations. In particular, we will be obligated to pay Alchemia Limited quarterly royalty payments equal to 5% all revenues received by us or on our behalf in each fiscal quarter in respect of sales of any products or services based on, incorporating or made utilizing the VAST technology, including any revenue received from any sub-licensee. In that regard, the license agreement does not permit us to sub-license any of the VAST technology without Alchemia Limited’s prior consent, which may not be unreasonably withheld.

The agreement will require us to deploy staff with relevant scientific qualifications occupying a minimum of four full-time equivalent positions to develop and exploit the VAST technology and to expend a minimum of

-106-

US$ per annum (with a target of expending US$ million per annum) on developing, marketing and exploiting the VAST technology and otherwise using our best endeavors to exploit the technology. If we fail to meet the targeted amount of expenditure of US$1.5 million per annum, Alchemia Limited will have the right to require that we consult with them on changes to our program for developing, marketing and exploiting the VAST technology to reach this annual target amount and, in that case, we will be required to comply with any commercially reasonable requests of Alchemia Limited regarding any required changes to that program. The agreement will be subject to termination by Alchemia Limited in the event of: (a) our bankruptcy, insolvency, receivership or similar events; (b) our failure to pay any amount due under the agreement for 20 business days after notice from Alchemia Limited; (c) a material breach of the agreement by us and that breach is not capable of remedy; or (d) a breach of the agreement by us and the breach is capable of remedy but we do not remedy the breach within 10 business days after notice from Alchemia Limited.

Under the license agreement, Alchemia Limited, after consultation with us, may initially determine whether or not to take any action against a third party that is infringing the VAST technology or to defend the validity of the VAST technology. However, Alchemia Limited will be under no obligation to take any such action and, if it chooses to take no action, we will have a right, at our own expense, to take action on behalf of Alchemia Limited. In addition, we will be obligated to file, prosecute and maintain the patents and patent applications relating to the VAST technology at our own cost and expense, and we will be entitled to make decisions relating to the prosecution and maintenance of the patents and patent applications.

See “Risk Factors — If we breach any of the agreements under which we license rights to patents or other intellectual property from third parties, we could lose license rights that are important to our business” and “We will not have the right to sub-license the VAST small molecule drug discovery technology without Alchemia Limited’s consent, which may prevent us from commercializing that technology.”

Government Regulations

Government authorities in the United States (including federal, state and local authorities) and in other countries extensively regulate the manufacture, research, clinical development, labeling, packaging, distribution, post-approval monitoring and reporting, advertising, promotion, export and import of pharmaceutical products, such as those we are developing. The process of obtaining and maintaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

United States

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FFDCA, and related regulations. Drugs are also subject to other federal, state and local statutes and regulations. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include the imposition by the FDA or an Institutional Review Board, or IRB, of a clinical hold on trials, the FDA’s refusal to approve pending applications or supplemental applications, withdrawal of an approval, warning letters, product recalls, product seizures, total or partial suspension of product or distribution, injunctions, fines, civil penalties or criminal prosecution. Any agency or judicial enforcement action could have a material adverse effect on us.

The Investigational New Drug Process

An Investigational New Drug application, or an IND, is a request for authorization from the FDA to administer an investigational drug to humans. Such authorization must be secured before commencing clinical trials of any new drug candidate in humans.

The central focus of the initial IND submission is on the general investigational plan and the protocol(s) for human studies. The IND also includes results of laboratory and animal studies, as well as manufacturing information, analytical data and any available clinical data or literature to support the use of the investigational new drug in humans. An IND must become effective before human clinical trials may begin. An IND will automatically become effective 30 days after the receipt by the FDA, unless before that time the FDA raises concerns or questions related to the proposed clinical trials as outlined in the IND. In such a case, the IND is placed on clinical hold until any outstanding concerns or questions are resolved.

Clinical trials involve the administration of the investigational drug to subjects or patients under the supervision of qualified investigators in accordance it Good Clinical Practices, or GCPs. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trials and the parameters to be used in monitoring safety and efficacy criteria. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. Additionally, approval must also be obtained from each clinical site’s IRB before the trials may be initiated. All participants in clinical trials must provide their informed consent in writing prior to their enrollment in the trial.

The clinical investigation of an investigational drug is generally divided into three phases. Although the phases are usually conducted sequentially, they may overlap or be combined. The three phases of an investigation are as follows:

•

Phase I: Phase I involves the initial introduction of an investigational drug into humans. Phase I clinical trials are typically closely monitored and maybe conducted in patients with the target disease or condition or healthy volunteers. These studies are designed to evaluate the safety, dosage tolerance, metabolism and pharmacological actions of the investigational drug in humans, the side effects associated with increasing doses, and if possible, to gain early evidence of effectiveness. During Phase I clinical trials, sufficient information about the investigational drug’s pharmacokinetic and pharmacologic effects may be obtained to permit the design of well-controlled and scientifically valid Phase II clinical trials.

•

Phase II: Phase II clinical trials are conducted to preliminarily or further evaluate the effectiveness of the investigational drug for a particular indication in patients with the disease or condition under study, to determine dosage tolerance and optimal dosage, and to identify possible adverse side effects and safety risks associated with the drug. Phase II clinical trials are typically well controlled, closely monitored and conducted in a limited patient population, usually involving no more than several hundred participants.

•

Phase III: Phase III clinical trials are conducted in an expanded patient population generally at geographically dispersed clinical trial sites. They are performed after preliminary evidence suggesting effectiveness of the drug has been obtained and are intended to further evaluate dosage, effectiveness and safety, to establish the overall benefit-risk relationship of the investigational drug, and to provide a scientific and statistical basis for product approval by the FDA.

The decision to terminate a study of an investigational drug may be made by us, the FDA or an Institutional Review Board. Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee. This group provides a recommendation of whether or not a trial may move forward at pre-specified check points based on access that only the group

-108-

maintains to available data from the trial. Suspension or termination of development during any phase of clinical trials can occur if it is determined that the participants or patients are being exposed to an unacceptable health risk. We may decide to suspend or terminate development based on evolving business objectives and/or the competitive climate.

In addition, there are regulations that require the posting of ongoing clinical trials on public registries and the disclosure of designated clinical trial results and related payments to healthcare professionals.

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed investigational drug information is submitted to the FDA in the form of a New Drug Application, or NDA, requesting approval to market the product for one or more indications.

In most cases, the FDA requires at least two adequate and well-controlled Phase III clinical trials to support marketing approval. However, in certain cases such as oncology where there is a significant unmet medical need, evidence from a single Phase III clinical trial may be sufficient. A single trial may also be sufficient in cases where a randomized, double-blind, multicenter study provides highly reliable and statistically strong evidence of an important clinical benefit, and where confirmation of the result in a second trial would be practically or ethically impossible.

The NDA Approval Process

In order to obtain approval to market a drug in the United States, a marketing application must be submitted to the FDA that provides data establishing substantial evidence of the safety and effectiveness of the investigational drug for the proposed indication to the FDA’s satisfaction. The application includes all relevant data available from pertinent preclinical and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a product, or from a number of alternative sources, including studies initiated by investigators.

The FDA will initially review the NDA for completeness before it accepts the NDA for filing. The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. After the NDA submission is accepted for filing, the FDA reviews the NDA to determined, among other things, whether the proposed product is safe and effective for its intended use, and whether the product is being manufactured in accordance with current Good Manufacturing Practices, or cGMP, to assure and preserve the product’s identity, strength, quality and purity. The FDA may refer applications for novel drug products or drug products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Based on Phase III clinical trial results submitted in an NDA, the FDA may assign the application a priority review designation, which sets the target date for FDA action on the application at six months. Priority review is given where preliminary estimates indicate that a product, if approved, has the potential to provide a safe and effective therapy where no satisfactory alternative therapy exists, or a significant improvement compared with marketed products is possible. If criteria are not met for priority review, the standard FDA review period is ten months. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

Before approving an NDA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in

-109-

compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCPs. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

Section 505(b)(2) New Drug Applications

Section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act permits the filing of an NDA where at least some of the information required for approval comes from prior studies used to support approval of a currently marketed drug which were not conducted by or for the applicant and for which the applicant has not obtained a right of reference. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval of a drug (the reference drug) is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of a new formulation of that reference drug. The FDA will generally require a company to perform additional studies to support approval of the new formulation or change from the reference drug. The FDA may then approve the new formulated drug candidate for all or some of the label indications for which the referenced drug has been approved, as well as for new indications sought by the 505(b)(2) applicant. We intend to utilize the 505(b)(2) regulatory pathway in seeking FDA approval of our HA-Irinotecan product candidate for the treatment of metastatic colorectal cancer, or mCRC, and for all of our other HyACT-targeted cancer compounds in development.

The testing and approval process for a drug requires substantial time, effort and financial resources and this process may take several years to complete. Data obtained from the clinical activities are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval on a timely basis, or at all. We may encounter difficulties or unanticipated costs in our efforts to develop our HA-Irinotecan for the treatment of mCRC or any other HyACT-targeted cancer compound and secure necessary governmental approvals, which could delay or preclude us from marketing our products. Even if the FDA approves HA-Irinotecan, it may limit the approved indications for use or place other conditions on approval that could restrict commercial application, such as a requirement that we implement special risk management measures through a Risk Evaluation and Mitigation Strategy.

Available Special Regulatory Procedures

Fast-Track Approval

Congress created a pathway to expedite the availability of a drug for seriously ill patients by establishing fast-track authority to FDA. Fast-track designation is available for drugs or biologics that demonstrate the potential to address unmet medical needs for serious or life-threatening conditions.

The sponsor must first request that the FDA designate its drug as a fast-track product. If the FDA concurs, approval may be based on the drug’s effect on a clinical endpoint or on a “surrogate endpoint” that reasonably suggests clinical benefit. Approval may be conditioned on the completion of postmarketing, or Phase IV, clinical studies to verify and describe the drug’s clinical benefit and to resolve remaining uncertainty about the endpoint on the basis of which the product was approved. Approval may also be subject to predissemination review requirements for promotional labeling and advertising, and to a streamlined procedure for withdrawal of approval if, among other reasons, a postmarketing clinical study fails to verify clinical benefit. The FDA may review marketing applications for fast-track products on a rolling basis, i.e., may begin review based on partial submissions.

Benefits of Fast-Track designation include scheduled meetings to seek FDA input into development plans, the option of submitting the NDA in sections rather than all components simultaneously, and the option of requesting evaluation of studies using surrogate endpoints.

-110-

Orphan Drug Designation

The FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition that affects fewer than 200,000 individuals in the United States, or if it affects more than 200,000 individuals in the United States and there is no reasonable expectation that the cost of developing and making the drug for this type of disease or condition will be recovered from sales in the United States. In the European Union, COMP grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating conditions affecting not more than 5 in 10,000 persons in the European Union community. Additionally, designation is granted for products intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of the drug in the European Union would be sufficient to justify the necessary investment in developing the drug or biological product.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. In addition, if a product and its active ingredients receive the first FDA approval for the indication for which it has orphan designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity.

In the European Union, orphan drug designation also entitles a party to financial incentives such as reduction of fees or fee waivers and 10 years of market exclusivity is granted following drug or biological product approval. This period may be reduced to six years if the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity or a safer, more effective or otherwise clinically superior product is available.

An application for marketing authorization can be submitted after the application for orphan drug designation has been submitted, while the designation is still pending but should be submitted prior to the designation application in order to obtain a fee reduction. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

Pediatric Development

In the United States, the FFDCA provides for an additional six months of marketing exclusivity for a drug if reports are filed of investigations studying the use of the drug product in a pediatric population in response to a written request from the FDA. Separate from this potential exclusivity benefit, NDAs must contain data (or a proposal for the collection of such data post-approval) to assess the safety and effectiveness of an investigational drug product for the claimed indications in all relevant pediatric populations in order to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults or full or partial waivers if certain criteria are met. Discussions about pediatric development plans can be discussed with the FDA at any time, but usually occur between the end-of-Phase II meeting and submission of the NDA.

For the EMA, a Pediatric Investigation Plan, and/or a request for waiver or deferral, is required for submission prior to submitting a marketing authorization application.

Post-Approval Regulation

After regulatory approval of a drug product is obtained, we would be required to comply with a number of post-approval requirements. For example, as a condition of approval of an NDA, the FDA may require post-

-111-

marketing testing and clinical trials and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization. Regulatory approval of oncology products often requires that patients in clinical trials be followed for long periods to determine the overall survival benefit of the drug. In addition, if any of our HyACT-targeted cancer product candidates are approved, we would be required to report, among other things, certain adverse reactions and production problems to the FDA, to provide updated safety and efficacy information, and to comply with regulations concerning advertising and promotional labeling for any of our products. Also, quality control and manufacturing procedures must continue to conform to cGMP after approval to assure and preserve the long-term stability of the drug product. The FDA periodically inspects manufacturing facilities to assess compliance with cGMP, which imposes extensive procedural, substantive and record-keeping requirements. In addition, changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require FDA approval before being implemented. FDA regulations would also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon us and any third-party manufacturers that we may decide to use if our product candidates are approved. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our HyACT-targeted product candidates. Future FDA inspections may identify compliance issues at our facilities or at the facilities of our contract manufacturers that may disrupt production or distribution, or require substantial resources to correct. In addition, discovery of previously unknown problems with a product or the failure to comply with applicable regulations may result in restrictions on a product, manufacturer or holder of an approved NDA, including withdrawal or recall of the product from the market or other voluntary, FDA-initiated or judicial action that could delay or prohibit further marketing. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

Europe/Rest of World Government Regulation

In addition to regulations in the United States, we are and will be subject, either directly or through our distribution partners, to a variety of regulations in other jurisdictions governing, among other things, clinical trials and any commercial sales and distribution of our products, if approved.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a process that requires the submission of a clinical trial application much like the IND prior to the commencement of human clinical trials. In Europe, for example, a clinical trial application, or CTA, must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials are conducted in accordance with GCP and other applicable regulatory requirements.

To obtain regulatory approval of an investigational drug under European Union regulatory systems, we must submit a marketing authorization application. This application is similar to the NDA in the United States, with the exception of, among other things, country-specific document requirements. Medicines can be authorized in the European Union by using either the centralized authorization procedure or national authorization procedures. We intend to use the centralized authorization procedure for our HyACT-targeted product candidates.

-112-

The EMA implemented the centralized procedure for the approval of human medicines to facilitate marketing authorizations that are valid throughout the European Union. This procedure results in a single marketing authorization granted by the European Commission that is valid across the European Union, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for human medicines that are: derived from biotechnology processes, such as genetic engineering; contain a new active substance indicated for the treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases and other immune dysfunctions; and officially designated orphan medicines. The centralized procedure may, subject to certain conditions, also be used for all products at the request of the applicant.

Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of a marketing authorization application is 210 days (excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the Committee for Medicinal Products for Human Use, or CHMP), with adoption of the actual marketing authorization by the European Commission thereafter. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest from the point of view of therapeutic innovation, defined by three cumulative criteria: the seriousness of the disease to be treated; the absence or insufficiency of an appropriate alternative therapeutic approach, and anticipation of high therapeutic benefit. In this circumstance, EMA ensures that the evaluation for the opinion of the CHMP is completed within 150 days and the opinion issued thereafter.

For other countries outside of the European Union, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials are conducted in accordance with GCP and the other applicable regulatory requirements.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension of clinical trials, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Compliance

During all phases of development and after product approval, failure to comply with the applicable regulatory requirements may result in administrative or judicial sanctions. These sanctions could include the following actions by the FDA or other regulatory authorities: imposition of a clinical hold on trials; refusal to approve pending applications; withdrawal of an approval; adverse publicity; warning letters; product recalls; product seizures; total or partial suspension of production or distribution; product detention or refusal to permit the import or export of products; injunctions, fines, civil penalties or criminal prosecution. Any agency or judicial enforcement action could have a material adverse effect on us.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we may obtain regulatory approval. In the United States and other countries, sales of any products for which we may receive regulatory approval for commercial sale will depend in part on the availability of reimbursement from third-party payors. Third-party payors include government health administrative authorities, managed care providers, private health insurers and other organizations. The process for determining whether a payor will provide coverage for a drug product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the drug product. Third-party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drugs for a particular indication. Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct

-113-

expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of our products, in addition to the costs required to obtain FDA and other approvals. Our HyACT-targeted products may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.

In 2003, the United States government enacted legislation providing a partial prescription drug benefit for Medicare recipients, which became effective at the beginning of 2006. Government payment for some of the costs of prescription drugs may increase demand for any products for which we receive marketing approval. However, to obtain payments under this program, we would be required to sell products to Medicare recipients through prescription drug plans operating pursuant to this legislation. These plans will likely negotiate discounted prices for our products. Federal, state and local government in the United States continue to consider legislation to contain healthcare costs, including the cost of prescription drugs. Future legislation could limit payments for pharmaceuticals such as the drug candidates that we are developing.

Different pricing and reimbursement schemes exist in other countries. In the European Union, governments influence the price of pharmaceutical products through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular HyACT-targeted product to currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and control company profits. In the European Union, the downward pressure on healthcare costs in general, particularly prescription drugs, has become very intense. As a result, it is becoming increasingly difficult to introduce and commercialize new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate, or decline to provide, coverage and reimbursement. In addition, an increasing emphasis on managed care in the United States has increased and we expect will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more product candidates for which we may receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Other Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services (formerly the Health Care Financing Administration), or CMS, other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice and individual U.S. Attorney offices within the Department of Justice, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-fraud and abuse provisions of the Social Security Act, the False Claims Act, the privacy provisions of the Health Insurance Portability and Accountability Act, or HIPAA, and similar state laws, each as amended. Pricing and rebate programs must comply with the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990 and the Veterans Health Care Act of 1992, each as amended. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. Under the Veterans Health Care Act, or VHCA, drug companies are required to offer certain drugs at a reduced price to a number of federal agencies including U.S. Department of Veteran Affairs and U.S. Department of Defense, the Public Health Service and certain private Public Health Service designated entities in order to participate in other federal

-114-

funding programs including Medicare and Medicaid. Recent legislative changes purport to require that discounted prices be offered for certain U.S. Department of Defense purchases for its TRICARE program via a rebate system. Participation under the VHCA requires submission of pricing data and calculation of discounts and rebates pursuant to complex statutory formulas, as well as the entry into government procurement contracts governed by the Federal Acquisition Regulations.

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities or register their sales representatives, as well as prohibiting pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and prohibiting certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

New Legislation and Regulations

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the testing, approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations and policies are often revised or interpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether further legislative changes will be enacted or whether FDA regulations, guidance, policies or interpretations changed or what the effect of such changes, if any, may be.

Patents and Proprietary Rights

The proprietary nature of, and protection for, our HyACT and in-licensed VAST technologies, product candidates, processes and know-how are vital to our business. Our success depends in significant part on our ability to protect the proprietary nature of our product candidates, technology, in-licensed technology and know-how, to operate without infringing on the proprietary rights of others, and to prevent others from infringing our proprietary rights. We have sought and plan to continue to seek patent protection in the United States and select foreign countries for our proprietary and in-licensed technologies. As of June 15, 2012, we own or have in-licensed approximately 9 pending patent applications, 16 issued patents and one allowed patent in the United States, as well as pending corresponding foreign patent applications and issued foreign patents. Our policy is to patent the technology, inventions and improvements that we consider important to the development of our business, but only in those cases where we believe that the costs of obtaining patent protection are justified by the commercial potential of the technology, and typically only in those jurisdictions that we believe present significant commercial opportunities. We also rely on trade secrets, know-how, our anticipated VAST in-license and continuing innovation to develop and maintain our competitive position. We cannot be sure that patents will be granted with respect to any of our pending patent applications, any patent applications filed by us in the future or any pending or future patent applications that have been or may be filed with respect to the VAST technology, nor can we be sure that any of our existing patents, any patents granted to us in the future or any patents in-licensed to us or that may be in-licensed to us in the future will be commercially useful in protecting our technology. In addition, we have patents and pending patent applications relating to the HyACT technology in the United States and a limited number of other jurisdictions, and we have in-licensed patents and pending patent applications relating to the VAST technology in the United States and a limited number of other jurisdictions, and, as a result, there are a large number of jurisdictions, including certain major markets, where we do not own or in-license any patents or pending patent applications.

-115-

Our owned and in-licensed patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in the various countries where patent protection is obtained. Our material owned and in-licensed patents relate to the VAST and HyACT technologies. Our patents relating to the HyACT technologies will expire, excluding possible patent extensions under the Hatch-Waxman Act (as defined below), on various dates between 2020 and 2026. The material patents relating to the VAST technology that we will in-license will expire, excluding possible patent extensions under the Hatch-Waxman Act, on various dates between 2017 and 2027. Several of these patents will have potential patent term adjustments and extensions, depending on the length of time required to conduct clinical trials and obtain regulatory approval.

The patent positions of biotechnology firms like us are generally uncertain and involve complex legal, scientific and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued. Consequently, we do not know whether any of the technologies covered by the patent applications that we own or in-license will gain patent protection or, if any patents are issued, whether they will provide significant proprietary protection or will be challenged, circumvented or invalidated. Because patent applications in the United States and certain other jurisdictions are maintained in secrecy for 18 months,

and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain of the priority of inventions covered by pending patent applications that we own or in-license. Moreover, we may have to participate in interference proceedings called by the U.S. Patent and Trademark Office, or PTO, or a foreign patent office to determine priority of invention, or in opposition proceedings in a foreign patent office, either of which could result in substantial cost to us, even if the eventual outcome is favorable to us, or may result in an unfavorable outcome. There can be no assurance that current or, if issued, new patents would be held valid by a court of competent jurisdiction. An adverse outcome could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties for significant royalty payments or require us to cease using specific compounds or technology.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we or, in the case of technology we have in-licensed, our licensor has filed, the patent term is 20 years from the earliest date of filing a non-provisional patent application. In the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the PTO in granting a patent, or may be shortened if a patent is terminally disclaimed over another patent.

The patent term of a patent that covers an FDA-approved drug may also be eligible for patent term extension, which permits patent term restoration as compensation for the patent term lost during the FDA regulatory review process. The Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review. Patent extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent applicable to an approved drug may be extended. Similar provisions are available in Europe and other non-U.S. jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our pharmaceutical product candidates receive FDA approval, we may apply for patent term extensions on patents covering those products.

To protect our rights to any of our issued patents and proprietary information, we may need to litigate against infringing third parties, or avail ourselves of the courts or participate in hearings to determine the scope and validity of those patents or other proprietary rights. In the case of any patents and proprietary information that we have in-licensed, we may not have the right to litigate against infringing parties except under limited circumstances specified in the applicable license agreement (which may include, for example, failure by the licensor to litigate against infringing parties), and we therefore may be entirely or primarily dependent upon proceedings instituted by the licensor to protect the relevant intellectual property. In those cases, the licensor may elect not to pursue infringement proceedings, which means that we may be unable to prevent third parties from utilizing the technology that we have in-licensed; likewise, a licensor may not devote its full resources to the

-116-

defense of the relevant intellectual property, which may result in an adverse decision in any infringement proceedings. In addition, these types of proceedings are often costly and could be very time-consuming to us, and we cannot assure you that the deciding authorities will rule in our favor. An unfavorable decision could allow third parties to use technology that we own or in-license without being required to pay us licensing fees, may compel us to pay substantial royalties to license needed technologies to avoid infringing third-party patent and proprietary rights or may require that we cease using certain products or technology, which may prevent us from using or producing certain product candidates or products for which we may receive regulatory approval. Such a decision could even result in the invalidation or a limitation in the scope of patents that we own or in-license or forfeiture of the rights associated with those patents or pending patent applications.

Under the license agreement pursuant to which we will in-license the VAST technology from Alchemia Limited, only Alchemia Limited, after consultation with us, may determine whether or not to take any action against a third party that we believe is infringing the VAST technology or in order to defend the validity of that technology. However, Alchemia Limited will be under no obligation to take any such action and, as a result, we may be unable to prevent third parties from infringing our in-licensed technology, which may have a material adverse effect on our ability to use and commercialize that technology.

We also rely on trade secret protection for our confidential and proprietary information. No assurance can be given that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technology, or that we can meaningfully protect our trade secrets.

It is our policy to require our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. There can be no assurance, however, that these agreements will provide meaningful protection for our trade secrets or adequate remedies in the event of unauthorized use or disclosure of such information.

For additional information, see “Risk Factors — Risks Related to Intellectual Property.”

Manufacturing

We do not own or operate any manufacturing facilities. We currently contract with third parties for the manufacture of our product candidates for preclinical studies and clinical trials and intend to do so in the future. The HA-Irinotecan for our Phase III and Phase II clinical trials is in the form of a kit, which is assembled by Almac Clinical Services Limited and distributed to trial sites as required. The kit contains the following components:

•

Camptosar-branded irinotecan hydrochloride, manufactured by, and sourced from, Pfizer Australia Pty Ltd.;

•

1% sodium hyaluronate solution in water for injection. This product is manufactured for us by Gland Pharma Ltd (India) using sodium hyaluronate from htl Biotechnology S.A.S. (France);

•

5% dextrose solution commercially sourced from Baxter Healthcare Ltd (UK); and

•

Consumables for preparation of solutions for infusion and conduct of the trial.

The hospitals utilize the kits to prepare bags containing HA-Irinotecan or irinotecan alone, which are used by healthcare staff for the pivotal Phase III clinical trial.

-117-

Except for the agreement with Novozymes referred to below, we have not entered into long-term agreements with contract manufacturers. We currently obtain our supplies of the components of our product candidates and the finished drug product through individual purchase orders. We currently have no plans to build our own clinical or commercial-scale manufacturing capabilities. If HA-Irinotecan for treatment of metastatic colorectal cancer receives regulatory approval following completion of our Phase III clinical trial, it is anticipated that the irinotecan hydrochloride, sodium hyaluronate and 5% dextrose solution will be centrally compounded by alternate suppliers, and presented to hospitals and prescribers ready for use, with no requirement for compounding at hospitals.

We entered into two agreements with Novozymes Biopharma DK A/S, or Novozymes, in July 2009. The first agreement is a supply agreement whereby we agree to use Novozymes as our exclusive supplier of HA for our HA-Irinotecan-based product and Novozymes agrees to supply us with HA and to use commercially reasonable endeavors to build and maintain sufficient manufacturing capacity to reliably supply us with HA, including the construction of a new HA production facility. Novozymes does not currently have the manufacturing capacity to supply HA in accordance with the agreement, and although the agreement provides that Novozymes use commercially reasonable endeavors to achieve such sufficient manufacturing capacity by no later than January 1, 2014, we cannot assure you that this will occur. Assuming that Novozymes is able to construct a manufacturing facility as contemplated by the agreement, the agreement calls for us to provide Novozymes with a rolling three year estimate of our annual need of HA. We are not obligated to forecast any minimum estimate. Upon acceptance of our forecast by Novozymes, we and Novozymes will each be obligated to purchase and supply, respectively, 100% of the total forecasted quantities for the first year based on an agreed scheme adjusted for price index changes. The forecast for the two remaining years are non-binding. Novozymes agrees that the price at which it supplies HA to us is to be the best price it offers to any of its customers for HA of a reasonably similar quality and volume. The supply agreement will remain in effect for the later of seven years from its commencement or five years after the date when Novozymes begins supplying us with HA. At the end of such term and any further term, the supply agreement will automatically extend for a further five years unless either party has given notice not to extend it.

To date, our third-party manufacturers have met our manufacturing requirements. We expect third-party manufacturers to be capable of providing sufficient quantities of our product candidates to meet anticipated commercial demands, if any of our product candidates is approved. We believe that there are alternate sources of supply that can satisfy our clinical and, if applicable, commercial requirements, although we cannot be certain that identifying and establishing relationships with such sources, if necessary, would not result in significant delay or material additional costs. If we are unable to arrange for such a third-party manufacturing source, or fail to do so on commercially reasonable terms, we may not be able to continue clinical trials or, if any of our product candidates receives regulatory approval, successfully produce and market our products.

-118-

Commercialization

Our operations to date have been primarily limited to organizing and staffing our company, taking steps to effect the Demerger and related transactions, acquiring, developing and securing our technology, undertaking preclinical studies and clinical trials of our product candidates and engaging in research and development. We have not yet demonstrated an ability to obtain regulatory approval, formulate and manufacture commercial-scale products, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, it is difficult to predict our future success and the viability of any commercial programs that we may choose to take forward if any of our product candidates receives regulatory approval.

We do not have any internal sales, marketing or distribution infrastructure. In the event any of our product candidates receives regulatory approval, we intend, where appropriate, to pursue commercialization relationships with pharmaceutical companies and other strategic partners providing for our products to be distributed through their sales and marketing organizations in order to gain access to global oncology markets. Over the longer term, we may ultimately build an internal commercial infrastructure to directly market and sell any HyACT-targeted drugs that may receive regulatory approval.

Research and Development

A significant portion of our operating expenses is related to research and development and we intend to maintain our strong commitment to research and development. Our research and development expenses totaled approximately $3.1 million in fiscal 2010, approximately $7.0 million in fiscal 2011 and approximately $4.3 million for the nine months ended March 31, 2012.

Employees

As of March 31, 2012, we had six full-time employees. We also make use of independent contractors on a regular basis. None of our employees is represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good.

Facilities

Our principal executive offices are located in San Francisco, California, where we lease approximately 300 square feet of office space under a lease that expires in June 2013 and that is subject to a three month renewal at our option. We also intend to lease approximately 25,000 square feet of office and lab space in Brisbane, Australia under a lease that will expire in June 2016 and we have access to approximately 3,500 square feet of lab space in Melbourne, Australia under a research and development agreement with Monash University that we first entered into in April 2004 and that is subject to annual renewal by both parties; the current term of this agreement expires in December 2012. We believe that our facilities are sufficient to meet our current needs and that suitable additional space will be available as and when needed.

Legal Proceedings

We are not currently a party to any material legal proceedings.

Board Composition; Classified Board

Our business affairs are managed under the direction of our board of directors, which is currently composed of 3 members. of our directors are independent within the meaning of the independent director guidelines of The Nasdaq Stock Market. In accordance with our amended and restated certificate of incorporation, which we intend to adopt in connection with this offering, our board of directors will be divided into three staggered classes of directors. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the same class whose terms are then expiring. The terms of the current directors will expire upon the election and qualification of successor directors at the annual meeting of stockholders to be held during the year for the Class I directors, for the Class II directors and for the Class III directors.

•

Our Class I directors will be .

•

Our Class II directors will be .

•

Our Class III directors will be .

Our amended and restated certificate of incorporation and bylaws will provide that the number of our directors shall be fixed from time to time by a resolution of our board of directors. Each of our executive officers serves at the discretion of our board of directors and holds office until his or her successor is duly appointed and qualified or until his or her earlier resignation or removal. There are no family relationships among any of our directors or executive officers.

The division of our board of directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change of control. See “Description of Capital Stock — Anti-Takeover

-122-

Effects of Delaware Law and Our Certificate of Incorporation and Bylaws” and “Risk Factors — Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock” for a discussion of these and other anti-takeover provisions found in our amended and restated certificate of incorporation and bylaws.

Director Independence

In connection with this offering, we intend to list our common stock on The Nasdaq Global Market. Under the rules of The Nasdaq Stock Market, independent directors must comprise a majority of a listed company’s board of directors within a specified period of the completion of an initial public offering. In addition, the rules of The Nasdaq Stock Market require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees must be independent. Under the rules of The Nasdaq Stock Market, a director is independent only if our board of directors makes an affirmative determination that the director has no material relationship with us.

In , 2012, our board of directors undertook a review of its composition, the composition of its committees and the independence of each director. The determination of independence of members of our board of directors was based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships. In making this determination, our board of directors considered the relationships that each non-employee director has with us and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. Our board of directors has determined that , representing of our directors, are “independent” as that term is defined under the rules of The Nasdaq Stock Market for purposes of serving on our board of directors.

Board Committees

Our board of directors has the authority to appoint committees to perform certain management and administrative functions. Our board of directors intends to have an audit committee, a compensation committee and a nominating and corporate governance committee, each of which is expected to have the composition and the responsibilities described below.

Non-Employee Director Compensation

We expect to reimburse our non-employee directors for expenses incurred in connection with attending board and committee meetings.

In addition, after this offering we intend to continue to reimburse our non-employee directors for expenses incurred in attending board and committee meetings. Members of our board of directors who are not our employees are expected to receive non-statutory stock options under our 2012 Equity Incentive Plan, which will become effective upon the closing of this offering. Each non-employee director on our board of directors on the date that we enter into the underwriting agreement for this offering or upon initially joining our board of directors after the completion of this offering is expected to be granted a non-statutory stock option to purchase shares of our common stock (in the case of directors on the date of the underwriting agreement) or a number of shares of our common stock equal to % of our common stock outstanding (in the case of directors initially joining our board of directors after completion of this offering), with an exercise price equal to the then fair market value of our common stock (which will be the initial public offering price appearing on the cover page of this prospectus in the case of options granted to our initial board of directors). On the date of each annual meeting of our stockholders beginning in , each non-employee director will be granted a non-statutory stock option to purchase a number of shares of our common stock equal to % of our common stock outstanding as of the record date for the applicable annual meeting. Initial stock option grants are expected to vest in a series of 36 successive equal monthly installments measured from the date of grant. Annual stock option grants are expected to vest in a series of 12 successive equal monthly installments measured from the date of grant. All director stock options granted under our 2012 Equity Incentive Plan are expected to have a term of ten years. Each option granted to a non-employee director is expected to vest in full immediately and automatically upon a change in control (as defined in our 2012 Equity Incentive Plan) of us.

Our named executive officers also will receive options to purchase our common stock at an exercise price equal to the initial public offering price set forth on the cover page of this prospectus in connection with the closing of this offering as follows: Dr. Smith will receive options to purchase shares of our common stock, Mr. Walker will receive options to receive options to purchase shares of our common stock and Associate Professor Brown will receive options to purchase shares of our common stock. These options are expected to vest in equal monthly installments over a -year period beginning on the grant date, and all of these options will have a -year term.

2012 Equity Incentive Plan

We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our employees and directors with the financial interests of our stockholders. In addition, we believe that our ability to grant stock options and other equity-based awards helps us to attract, retain and motivate qualified employees, and encourages them to devote their best efforts to our business and financial success. The following is a description of some of the expected terms of our 2012 Equity Incentive Plan, which we expect will become effective upon completion of this offering. This summary does not purport to be complete and is qualified in its entirety by the provisions of our 2012 Equity Incentive Plan. For more complete information, you should review the form of our 2012 Equity Incentive Plan which will be filed as an exhibit to the registration statement of which this prospectus is a part.

In 2012, our board of directors and our stockholders approved our 2012 Equity Incentive Plan. Our 2012 Equity Incentive Plan permits the grant of incentive stock options, within the meaning of Section 422 of the Code, to our employees and any of our subsidiary corporations’ employees, and the grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units and performance shares to our employees, directors and consultants and our subsidiaries’ employees and consultants.

Authorized Shares

The maximum aggregate number of shares issuable under the 2012 Equity Incentive Plan is shares of our common stock. In addition, the number of shares available for issuance under the 2012 Equity Incentive Plan will be annually increased on the first day of each of our fiscal years beginning with the fiscal year commencing July 1, , provided, that our board of directors specifically approves the increase, by an amount equal to the least of:

•

shares;

•

% of the outstanding shares of our common stock as of the last day of our immediately preceding fiscal year; or

•

such other amount as our board of directors may determine.

Shares issued pursuant to awards under the 2012 Equity Incentive Plan that we repurchase or that expire, become unexercisable or are forfeited, shares that are surrendered pursuant to an exchange program, pursuant to which outstanding awards may be surrendered in exchange for awards that have different exercise prices and terms, as well as shares used to pay the exercise price of an award or to satisfy the tax withholding obligations related to an award, will become available for future grant under the 2012 Equity Incentive Plan. In addition, to the extent that an award is paid out in cash rather than shares, such cash payment will not reduce the number of shares available for issuance under the 2012 Equity Incentive Plan. With respect to stock appreciation rights, only shares actually issued pursuant to the award cease to be available under the 2012 Equity Incentive Plan.

-131-

Plan Administration

Our board of directors or one or more committees appointed by our board of directors will administer the 2012 Equity Incentive Plan. It is anticipated that the compensation committee of the board of directors will administer the 2012 Equity Incentive Plan. In the case of awards intended to qualify as “performance-based compensation” within the meaning of Code Section 162(m), the committee will consist of two or more “outside directors” within the meaning of Code Section 162(m).

Subject to the provisions of our 2012 Equity Incentive Plan, the plan administrator has the power to determine the terms of awards, including the recipients, the exercise price, if any, the number of shares covering each award, the fair market value of a share of our common stock, the vesting schedule applicable to the awards, together with any vesting acceleration, the form of consideration, if any, payable upon exercise of the award, and the terms of the award agreement for use under the 2012 Equity Incentive Plan. The plan administrator also has the authority, subject to the terms of the 2012 Equity Incentive Plan, to amend existing awards to reduce or increase their exercise price, to allow participants the opportunity to transfer outstanding awards to a financial institution or other person or entity selected by the plan administrator, to institute an exchange program by which outstanding awards may be surrendered in exchange for awards that may have different exercise prices and terms, to prescribe rules and to construe and interpret the 2012 Equity Incentive Plan and awards granted under the 2012 Equity Incentive Plan.

Stock Options

The plan administrator may grant incentive and/or nonstatutory stock options under our 2012 Equity Incentive Plan, provided that incentive stock options are only granted to employees. The exercise price of such options must equal at least the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed 10 years; provided, however, that an incentive stock option held by a participant who owns more than 10% of the total combined voting power of all classes of our stock, or of certain of our subsidiaries, may not have a term in excess of five years and must have an exercise price of at least 110% of the fair market value of our common stock on the grant date. The plan administrator will determine the methods of payment of the exercise price of an option, which may include cash, shares or other property acceptable to the plan administrator, as well as other types of consideration permitted by applicable law. Subject to the provisions of our 2012 Equity Incentive Plan, the plan administrator determines the remaining terms of the options (e.g., vesting). After the termination of service of an employee, director or consultant, the participant may exercise his or her option, to the extent vested as of such date of termination, for the period of time stated in his or her option agreement. However, in no event may an option be exercised later than the expiration of its term.

Stock Appreciation Rights

Stock appreciation rights may be granted under our 2012 Equity Incentive Plan. Stock appreciation rights allow the recipient to receive the appreciation in the fair market value of our common stock between the exercise date and the date of grant. Subject to the provisions of our 2012 Equity Incentive Plan, the plan administrator determines the terms of stock appreciation rights, including when such rights vest and become exercisable and whether to settle such awards in cash or with shares of our common stock, or a combination thereof, except that the per share exercise price for the shares to be issued pursuant to the exercise of a stock appreciation right will be no less than 100% of the fair market value per share on the date of grant. The specific terms of any grant of stock appreciation rights will be set forth in an award agreement between us and the recipient.

Restricted Stock

Restricted stock may be granted under our 2012 Equity Incentive Plan. Restricted stock awards are grants of shares of our common stock that are subject to various restrictions, including restrictions on transferability and

-132-

forfeiture provisions. Shares of restricted stock will vest and the restrictions on such shares will lapse, in accordance with terms and conditions established by the plan administrator. Such terms may include, among other things, vesting upon the achievement of specific performance goals determined by the plan administrator and/or continued service to us. The plan administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed. Recipients of restricted stock awards generally will have voting and dividend rights with respect to such shares upon grant without regard to vesting, unless the plan administrator provides otherwise. Shares of restricted stock that do not vest for any reason will be forfeited by the recipient and will revert to us. The specific terms of any grant of restricted stock will be set forth in an award agreement between us and the recipient.

Restricted Stock Units

Restricted stock units may be granted under our 2012 Equity Incentive Plan. Each restricted stock unit granted is a bookkeeping entry representing an amount equal to the fair market value of one share of our common stock. The plan administrator determines the terms and conditions of restricted stock units including the vesting criteria, which may include achievement of specified performance criteria or continued service to us, and the form and timing of payment. The plan administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed. The plan administrator determines in its sole discretion whether an award will be settled in stock, cash or a combination of both. The specific terms of any grant of restricted stock units will be set forth in an award agreement between us and the recipient.

Performance Units/Performance Shares

Performance units and performance shares may be granted under our 2012 Equity Incentive Plan. Performance units and performance shares are awards that will result in a payment to a participant only if performance goals established by the plan administrator are achieved or the awards otherwise vest. The plan administrator will establish organizational or individual performance goals in its discretion, which, depending on the extent to which they are met, will determine the number and/or the value of performance units and performance shares to be paid out to participants. After the grant of a performance unit or performance share, the plan administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such performance units or performance shares. Performance units shall have an initial dollar value established by the plan administrator prior to the grant date. Performance shares will have an initial value equal to the fair market value of our common stock on the grant date. The plan administrator, in its sole discretion, may pay earned performance units or performance shares in the form of cash, in shares or in some combination thereof. The specific terms of any grant of performance units and performance shares will be set forth in an award agreement between us and the recipient.

Transferability of Awards

Unless the plan administrator provides otherwise, our 2012 Equity Incentive Plan generally does not allow for the transfer of awards and only the recipient of an award may exercise such an award during his or her lifetime.

Certain Adjustments

In the event of certain changes in our capitalization, to prevent diminution or enlargement of the benefits or potential benefits available under the 2012 Equity Incentive Plan, the plan administrator will make adjustments to one or more of the number and class of shares that may be delivered under the plan and/or the number, class, exercise price and price of shares covered by each outstanding award and the numerical share limits contained in the 2012 Equity Incentive Plan. In the event of our proposed liquidation or dissolution, the plan administrator will notify participants as soon as practicable and all awards will terminate immediately prior to the consummation of such proposed transaction.

-133-

Merger or Change of Control

Our 2012 Equity Incentive Plan provides that in the event of our merger or change of control, as defined under the 2012 Equity Incentive Plan, each outstanding award will be treated as the plan administrator determines, except that if a successor corporation or its parent or subsidiary does not assume or substitute an equivalent award for any outstanding award of ours, then such award will fully vest, all restrictions on such award will lapse, all performance goals or other vesting criteria applicable to such award will be deemed achieved at 100% of target levels and such award will become fully exercisable, if applicable, for a specified period prior to the transaction. The award will then terminate upon the expiration of the specified period of time. If the service of an outside director is terminated on or following a change of control, other than pursuant to a voluntary resignation, his or her awards will become fully vested and exercisable, and all performance goals or other vesting requirements will be deemed achieved at 100% of target levels.

Plan Amendment; Termination

Our board of directors has the authority to amend, suspend or terminate the 2012 Equity Incentive Plan provided such action does not impair the existing rights of any participant. Our 2012 Equity Incentive Plan will automatically terminate in 2022, unless we terminate it sooner.

401(k) Plan

We currently do not have any U.S. employees. If we have any U.S. employees, we may elect to establish a tax-qualified retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation subject to applicable annual Code limits. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. Employees are immediately and fully vested in their contributions. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.

Limitations on Liability and Indemnification Matters

Upon the closing of this offering, our amended and restated certificate of incorporation will contain provisions that limit the liability of our current and former directors for monetary damages to the fullest extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for any breach of fiduciary duties as directors, except liability for:

•

any breach of the director’s duty of loyalty to the corporation or its stockholders;

•

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•

any unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

•

any transaction from which the director derived an improper personal benefit.

This limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

Our amended and restated certificate of incorporation and our amended and restated bylaws will provide that we are required to indemnify our directors to the fullest extent permitted by Delaware law. Our amended and

-134-

restated bylaws will also provide that, upon satisfaction of specified conditions, we are required to advance expenses incurred by a director in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law. Our amended and restated bylaws will also provide our board of directors with discretion to indemnify our officers and employees when determined appropriate by the board of directors. We expect to enter into agreements to indemnify our directors and executive officers, if applicable, as determined by the board of directors. With specified exceptions, these agreements will provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these amended and restated certificate of incorporation and bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also will maintain customary directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions. At present, there is no pending litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought and we are not aware of any threatened litigation that may result in claims for indemnification.

Rule 10b5-1 Sales Plan

Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or officer when entering into the plan, without further direction from them. The director or officer may amend a Rule 10b5-1 plan in some circumstances and may terminate a plan at any time. Our directors and executive officers also may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information subject to compliance with the terms of our insider trading policy. Our directors or executive officers may not establish any such plan prior to the expiration of the lock-ups described under “Underwriting—Lock-up Agreements.”

Indemnification Agreements

Our amended and restated certificate of incorporation and bylaws will provide that we will indemnify our directors and executive officers to the fullest extent permitted by Delaware law. In addition, we have entered into indemnification agreements with each of our directors and executive officers that may be broader in scope than the specific indemnification provisions contained in the Delaware General Corporation Law. For more information regarding these agreements, see “Executive Compensation — Limitations on Liability and Indemnification Matters.”

Policies and Procedures for Related Party Transactions

Prior to this offering, we have not had a formal policy regarding approval of transactions with related parties. Prior to the completion of this offering, we expect to adopt a related person transaction policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. The policy will become effective immediately upon the execution of the underwriting agreement for

-136-

this offering. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any related person are, were or will be participants in which the amount involved exceeds $120,000. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management must present information regarding the related person transaction to our audit committee, or, if audit committee approval would be inappropriate, to another independent body of our board of directors, for review, consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third-party or to or from employees generally. Under the policy, we will collect information that we deem reasonably necessary from each director, executive officer and, to the extent feasible, significant stockholder to enable us to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under our Code of Business Conduct and Ethics, which we will adopt in connection with this offering our employees and directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, our audit committee, or other independent body of our board of directors, will take into account the relevant available facts and circumstances including, but not limited to:

•

the risks, costs and benefits to us;

•

the impact on a director’s independence in the event that the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

•

the availability of other sources for comparable services or products; and

•

the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

The policy will require that, in determining whether to approve, ratify or reject a related person transaction, our audit committee, or other independent body of our board of directors, must consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our stockholders, as our audit committee, or other independent body of our board of directors, determines in the good faith exercise of its discretion.

ARRANGEMENTS BETWEEN AUDEO ONCOLOGY, INC. AND ALCHEMIA LIMITED

We have provided below a description of some of the terms of the intra-group transfer agreement between us and Alchemia Limited and some of the other agreements that relate to the Demerger. This description is not complete and is qualified in its entirety by the provisions of those agreements. You should read the full text of these agreements, which have been or will be filed with the SEC as exhibits to the registration statement of which this prospectus is a part.

Intra-group Transfer Agreement

On June 28, 2012, we and Alchemia Limited entered into an intra-group transfer agreement pursuant to which on June 28, 2012:

•

Alchemia Limited transferred to us its shares in Alchemia Oncology Pty Limited; and

•

we issued 7.5 million shares of our common stock to Alchemia Limited.

In addition, we agreed to issue to Alchemia Limited such number of additional shares of our common stock as is required to ensure that Alchemia Limited has a sufficient number of shares of our common stock to distribute to holders of ordinary shares of Alchemia Limited on the record date for the Demerger, as required by the terms of the Demerger.

The agreement provides for us to assume Alchemia Limited’s obligation to issue the Warrants described in “Prospectus Summary — The Offering.” We agreed to indemnify Alchemia Limited in respect of any liability or loss suffered by Alchemia Limited if we fail to issue the Warrants.

Technology License Agreement

On , 2012, our subsidiary, Audeo Discovery Pty Limited, entered into a Technology License Agreement with Alchemia Limited. The license agreement provides Audeo Discovery Pty Limited with a non-transferable, worldwide license to use Alchemia Limited’s VAST technology, including related patents, patent applications and know-how. The license is exclusive except in relation to one family of patents in respect of which there is an existing non-exclusive third party license. Under the Technology License Agreement, Audeo Discovery Pty Limited is subject to development obligations, reporting obligations, sublicense revenue sharing requirements, royalty payments and other obligations. In particular, Audeo Discovery Pty Limited must pay Alchemia Limited quarterly royalty payments equal to 5% of the net revenue received by Audeo Discovery Pty Limited in each fiscal quarter in respect of sales of any products or services based on, incorporating or made utilizing the VAST technology, or sub-licensing of the VAST technology. In that regard, the license agreement does not permit us to sub-license any of the VAST technology without Alchemia Limited’s prior consent, which may not be unreasonably withheld.

The Technology License Agreement will require Audeo Discovery Pty Limited to deploy staff with relevant scientific qualifications occupying a minimum of four full-time equivalent positions to develop and exploit the VAST technology and to expend a minimum of US$ per annum (with a target of expending US$ million per annum) on developing, marketing and exploiting the VAST technology and otherwise using its best endeavors to exploit the technology. If Audeo Discovery Pty Limited fails to meet the targeted amount of expenditure of US$1.5 million per annum, Alchemia Limited will have the right to require that Audeo Discovery Pty Limited consult with it on changes to the program for developing, marketing and exploiting the VAST technology to reach this annual target amount and, in that case, Audeo Discovery Pty Limited will be required to comply with any commercially reasonable requests of Alchemia Limited regarding any required changes to that program. The agreement will be subject to termination by Alchemia Limited in the event of:

-138-

(a) the bankruptcy, insolvency, receivership or similar events relating to Audeo Discovery Pty Limited; (b) Audeo Discovery Pty Limited’s failure to pay any amount due under the agreement for 20 business days after notice from Alchemia Limited; (c) a material breach of the agreement by Audeo Discovery Pty Limited and that breach is not capable of remedy; or (d) a breach of the agreement by Audeo Discovery Pty Limited and the breach is capable of remedy but Audeo Discovery Pty Limited does not remedy the breach within 10 business days after notice from Alchemia Limited.

Transitional Services Agreement

On , 2012, we entered into a transitional services agreement with Alchemia Limited pursuant to which we will provide certain accounting, payroll, treasury, management, tax, investor relations, information technology, office facilities and administrative services to Alchemia Limited following the Demerger. Under the agreement, Alchemia Limited must pay monthly service charges (calculated on a cost recovery basis) and our out-of-pocket expenses in providing the services. The services are to be provided until six months after the implementation of the Demerger although Alchemia Limited may terminate the agreement on five business days notice. Either party may terminate the agreement for an uncured breach by the other, if an insolvency event occurs in relation to the other party or by mutual agreement.

In addition, pursuant to the terms of the transitional services agreement, Peter Smith, our Chief Executive Officer and President, and Charles Walker, our Chief Financial officer, will be seconded, on a part time basis, to Alchemia Limited as its Chief Executive Officer and Chief Financial Officer respectively until six months after the date of the implementation of the Demerger. Dr. Smith and Mr. Walker will not receive any additional compensation from us or from Alchemia Limited for their services to Alchemia Limited, although Alchemia Limited will reimburse us for their services.

Alchemia Limited has agreed not to offer to employ any of our employees until at least 12 months after the services are last provided by us under the transitional services agreement. We have agreed to use all reasonable endeavors to provide the services although we will not be liable for any failure to provide the services in accordance with the terms of the agreement unless such failure is caused by our gross negligence or wilful act or omission. The parties have agreed to certain financial caps and time limits on any claims under the agreement. Neither party is liable for loss of profits or indirect or other consequential loss in relation to the provision of the services.

On , 2012, we entered into a sub-lease in relation to a part of the office space leased by us in Brisbane, Australia which allows Alchemia Limited to use part of our facilities. This sub-lease provides for Alchemia Limited to pay us rent calculated on a cost recovery basis. The term of the sub-lease is .

Under the Demerger Deed, Alchemia Limited will agree to effect the Demerger (including distributing shares of our common stock to Alchemia Limited’s shareholders) as contemplated by the Demerger scheme booklet. In addition, Alchemia Limited will agree to transfer cash and cash equivalents in the amount of $ and other assets in the amount of $ to us, and we will agree to assume employee entitlement liabilities from Alchemia Limited in the amount of $ , in connection with the Demerger.

If an asset which belongs to the businesses of Alchemia Oncology Pty Limited is not transferred to us within 24 months of the Demerger date, Alchemia Limited must transfer that asset. If an asset which belongs to the business of Alchemia Limited after the Demerger is not transferred to Alchemia Limited within 24 months of the Demerger date, we must transfer that asset.

We agree to use our best endeavors to release any guarantees or financial support which is provided by Alchemia Limited in relation to the businesses of Alchemia Oncology Pty Limited.

Except as permitted under the Transitional Services Agreement, the Technology License Agreement or any other Demerger document described above or below, Alchemia Limited must cease using any intellectual property relating to the businesses of Alchemia Oncology Pty Limited and we must cease using any intellectual property relating to the remaining business of Alchemia Limited (excluding any intellectual property that Alchemia Limited has licensed to us).

We have agreed to use our best endeavors to novate or assign any contract which relates to the business of Alchemia Limited after the Demerger. Alchemia Limited agrees to use its best endeavours to novate or assign any contract which relates to the businesses of Alchemia Oncology Pty Limited or Audeo Discovery Pty Limited after the Demerger.

We and Alchemia Limited have agreed to assist each other in relation to the management of litigation matters. We have agreed to indemnify Alchemia Limited in respect of liability or loss suffered by Alchemia Limited in connection with a claim arising from such litigation matters where that liability relates to the business of Alchemia Oncology Pty Limited. Alchemia Limited has agreed to indemnify us in respect of liability or loss suffered by us in connection with a claim arising from such litigation matters where that liability relates to the business of Alchemia Limited (other than the business of Alchemia Oncology Pty Limited).

Alchemia Limited has agreed to indemnify us for any liability arising from any Alchemia Limited current or past employee arising from their employment with or termination of employment by Alchemia Limited.

Alchemia Limited will remain liable for all of its income tax, and will be entitled to any tax refunds payable to it, for the period prior to and after the Demerger. We will be responsible for all income tax payable by, and will be entitled to any tax refunds payable to, Alchemia Oncology Pty Limited for the period prior to and after the Demerger. We and Alchemia Limited will assist each other in relation to the preparation of our respective tax returns and in the event of any tax audit by a relevant authority. The Demerger Deed also contains provisions as to the handling of any tax audit or review conducted by a governmental agency.

Demerger Implementation Agreement

On , 2012, we entered into the Demerger Implementation Agreement with Alchemia Limited which sets out the steps required to be taken by each of Alchemia Limited and us to give effect to the Demerger and other steps necessary to give effect to the Demerger.

Under the Demerger Implementation Agreement, we have agreed that we will take certain steps necessary or required to implement the Demerger including:

•

entering into deeds of access, indemnity and insurance with our directors;

•

applying to the SEC for admission to NASDAQ, preparing the registration statement of which this prospectus forms a part, and using our best endeavors to ensure that the SEC grants an order of effectiveness for such registration statement and trading in our shares of common stock commences as soon as possible following the date of the Demerger;

•

applying for admission to the Australian Securities Exchange, preparing a listing memorandum and using our best endeavours to ensure that the Australian Securities Exchange grants approvals for our application for admission and trading in our CDIs commences as soon as possible following the date of the Demerger;

•

executing the underwriting agreement for this offering and using our best endeavours to ensure the underwriting agreement proceeds to closing; and

•

if the scheme becomes effective, registering the transfer of our CDIs required to be transferred under the terms of the scheme.

The Demerger Implementation Agreement also contains details of the order in which the obligations of the parties as mentioned are to be performed, and certain other steps to be completed by Alchemia Limited and us in order to give effect to the implementation of the Demerger.

It is a condition subsequent to implementation of the Demerger that this offering closes by , 2012.

We and Alchemia Limited will also enter into a deed poll under which we will covenant, in favor of each Alchemia Limited shareholder who is eligible to participate in the scheme and holders of Warrants, to perform our respective obligations under the Demerger Implementation Agreement.

PRINCIPAL STOCKHOLDERS

The following table sets forth the beneficial ownership of our common stock as of June 28, 2012, and as adjusted to reflect the distribution of shares of our common stock to Alchemia Limited shareholders in the Demerger and sale of common stock offered by us in this offering, for:

•

each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our common stock;

•

each of our named executive officers;

•

each of our directors; and

•

all of our executive officers and directors as a group;

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities and include shares of common stock issuable upon the exercise of stock options that are immediately exercisable or exercisable within 60 days after , 2012. Common stock subject to stock options exercisable immediately or within 60 days of June 28, 2012, is deemed to be outstanding for computing the percentage ownership of the person holding these options and the percentage ownership of any group of which the holder is a member but are not deemed outstanding for computing the percentage ownership of any other person. Except as otherwise indicated, all of the shares reflected in the table are shares of common stock and all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information is not necessarily indicative of beneficial ownership for any other purpose.

Information regarding any person or group that will beneficially own more than 5% of our outstanding common stock following the Demerger and this offering is based upon Alchemia Limited’s stock records as of , 2012.

Percentage ownership calculations prior to the Demerger and this offering are based on shares of our common stock outstanding as of , 2012. Percentage ownership calculations after the Demerger and this offering are based on the assumption that (i) we will issue shares of our common stock in this offering (assuming the underwriters do not exercise their overallotment option) and (ii) shares of our common stock will be distributed (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution to Alchemia Limited’s shareholders of one share of our common stock for every outstanding ordinary shares of Alchemia Limited. However, the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012 and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. As a result, the actual number of shares of our common stock distributed in the Demerger and that will be outstanding immediately after this offering and the Demerger will be different than the number of shares we have assumed for the purposes of the following table.

DESCRIPTION OF CAPITAL STOCK

General

The following is a description of some of the terms of our common stock and preferred stock, certain warrants that we will issue following this offering, certain provisions of our amended and restated certificate of incorporation and bylaws, as they will be in effect upon the completion of this offering, and certain provisions of the Delaware General Corporation Law, or the DGCL. This summary does not purport to be complete and is qualified in its entirety by the provisions of our amended and restated certificate of incorporation and bylaws, as they will be in effect upon completion of this offering and the relevant provisions of the DGCL. For more complete information, you should review the forms of our amended and restated certificate of incorporation and bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part.

Immediately following the completion of this offering, our authorized capital stock will consist of shares, with a par value of $0.001 per share, of which:

•

shares are designated as common stock; and

•

shares are designated as preferred stock.

As of March 31, 2012, we would have had outstanding shares of common stock held by approximately stockholders of record, determined on a pro forma basis by assuming completion of the Demerger as of that date and based on the number of ordinary shares and the number of shareholders of Alchemia Limited as of March 31, 2012 and assuming that all stockholders of Alchemia Limited elect to receive shares of our common stock in the Demerger, and no shares of outstanding preferred stock. As noted above under “Prospectus Summary — The Offering,” the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012 and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. In addition, Alchemia Limited shareholders will receive CDIs in the Demerger, unless they elect to receive shares of our common stock, which will reduce the number of shareholders of record of our common stock following the Demerger. As a result, the actual number of shares of our common stock distributed in the Demerger and that will be outstanding immediately after this offering and the number of our stockholders of record after giving effect to such transactions, will be different from the number of shares and number of stockholders of record set forth above. For an analysis showing how changes in the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger would change the estimated number of shares of our common stock distributed in the Demerger and that will be outstanding immediately upon completion of this offering, see “Prospectus Summary — The Offering.”

Common Stock

The holders of common stock are entitled to one vote per share on all matters submitted to a vote of our stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the outstanding shares of our common stock may elect all of the directors standing for election. Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of outstanding shares of common stock

-144-

are entitled to receive ratably any dividends declared by our board of directors out of assets legally available. It is our present intention not to pay any cash dividends on our common stock for the foreseeable future. See the section above entitled “Dividend Policy.” Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of or provision for our liabilities and the liquidation preference of any then outstanding shares of preferred stock. Holders of common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock.

Preferred Stock

Pursuant to our certificate of incorporation, our board of directors will have the authority, without further action by the stockholders, to issue from time to time up to shares of preferred stock in one or more series. Our board of directors may designate the rights, preferences, privileges and restrictions of the preferred stock of any series, which may include dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund provisions and the number of shares constituting such series. The issuance of preferred stock could have the effect of restricting or preventing the payment of dividends on our common stock (if we were in the future to elect to pay dividends on our common stock) or the amounts, if any, paid to holders of our common stock in the event of our liquidation, dissolution or winding up or diluting the voting power of the common stock. Such issuance could have the effect of decreasing the market price of the common stock. The issuance of preferred stock or even the ability to issue preferred stock could also have the effect of delaying, deterring or preventing a change in control of our company. We currently have no plans to issue any shares of preferred stock.

Warrants

In November and December 2011, Alchemia Limited issued and sold its ordinary shares in a private placement, or the Placement, for total net proceeds of approximately AUD$16.1 million. Pursuant to the terms of the Placement, the investors were given rights, or the Rights, pursuant to which we are required, contingent on completion of this offering, to issue the Warrants to the investors entitling them to acquire shares of our common stock. The exercise price of the Warrants will be equal to 130% of the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price for such period as the Average Trading Price). The number of shares of our common stock, or the Warrant Shares, that will be issuable upon exercise of those Warrants will be equal to the quotient obtained by dividing (1) AUD$8,073,000 (equivalent to approximately US$8,066,542 based on the average of the currency exchange rates on November 11, 2011 and December 21, 2011, the dates on which the private placement closed) by (2) 130% of the Average Trading Price. Assuming an Average Trading Price of US$ per share (the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus) and an exchange rate of US dollars for one Australian dollar, approximately Warrant Shares would be issuable upon exercise of the Warrants at an exercise price of approximately US$ per share. However, because the number of Warrant Shares and exercise price both depend upon the actual Average Trading Price following this offering and the number of Warrant Shares also depends upon the exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. See “Prospectus Summary — The Offering” for an analysis that shows how changes in the Average Trading Price change the number of Warrant Shares issuable upon exercise of the Warrants and the exercise price of the Warrants and how changes in the currency exchange rate affect the number of Warrant Shares issuable upon such exercise. In addition, the number of Warrant Shares and/or the exercise price are subject to adjustment pursuant to the terms of the Warrants, including in the event of stock splits, stock combinations and similar events as well as in the event of dividends or other distributions on our shares of common stock.

•

three years from the IPO Date; and

•

Any Warrant that is not exercised prior to the Expiry Date will automatically expire on the Expiry Date.

CHESS Depositary Interests

In the Demerger, Alchemia Limited’s shareholders will receive CHESS Depository Interests, or CDIs, representing shares of our common stock or, at their option, shares of our common stock. Alchemia Limited will deliver the shares of our common stock represented by the CDIs to a depositary (which we expect will be CHESS Depositary Nominees Pty Ltd, a subsidiary of the Australian Securities Exchange, or another entity authorized to act as a depositary under the ASX Settlement Operating Rules), which will hold such shares as trustee on behalf of the holders of the CDIs. The holders of the CDIs will be the beneficial owners of, and will be entitled to exchange their CDIs for, the underlying shares of our common stock held by the depositary. In addition, holders of CDIs will generally be entitled to exercise the same voting and other rights as holders of our common stock, although they will be required to exercise those rights indirectly through the depositary unless they request the depositary to grant them a proxy to vote directly. Nonetheless, holders of CDIs will have substantially the same economic, voting and other rights as holders of our common stock and the CDIs therefore should be considered as the functional equivalents of shares of our common stock. In addition, holders of shares of our common stock, including shares sold in this offering, will be permitted to deliver those shares to the depositary in exchange for CDIs.

The purpose of the CDIs is to facilitate trading, settlement and clearance in Australia by shareholders of Alchemia Limited who would otherwise receive shares of our common stock in the Demerger. Because our common stock will not be listed on a securities exchange in Australia, Australian residents wishing to trade our common stock would be required to do so through The Nasdaq Global Market in transactions settled in U.S. dollars, which may be inconvenient due to time zone and currency differences, among other factors. However, because we plan to list the CDIs on the Australian Securities Exchange, Alchemia Limited shareholders who receive CDIs in the demerger will be able to trade those CDIs on a local Australian market in transactions settled in Australian dollars, beginning on the trading day in Australia following the date of this prospectus.

Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Provisions in our certificate of incorporation and bylaws, as amended and restated in connection with this offering, may have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions and certain provisions of Delaware law, which are described below, could discourage takeovers, coercive or otherwise. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us. However, these anti-takeover provisions may prevent a change in control or other takeover of our company that our stockholders consider to be in our best interest, including transactions that might result in a premium being paid over the market price of our common stock, and may also limit the price that investors are willing to pay for our common stock. These provisions may also have the effect of preventing changes in our management.

-146-

Undesignated Preferred Stock

As discussed above, our board of directors has the ability, without further action by the stockholders, to designate and issue preferred stock with voting or other rights or preferences that could deter hostile takeovers or delay changes in our control or management.

Limits on Ability of Stockholders to Act by Written Consent or Call a Special Meeting

Our amended and restated certificate of incorporation will provide that our stockholders may not act by written consent. This limit on the ability of stockholders to act by written consent means that any action taken by our stockholders may only be effected at a duly called annual or special meeting, which may lengthen the amount of time required to take stockholder actions.

In addition, our amended and restated bylaws will provide that special meetings of the stockholders may be called only by our board of directors, the chairman of the board of directors, our chief executive officer or our president (in the absence of our chief executive officer). A stockholder may not call a special meeting, which may delay the ability of our stockholders to force consideration of a proposal or for holders controlling a majority of our capital stock to take any action, including the removal of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our amended and restated bylaws will establish advance notice procedures with in order for stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee of the board of directors, to be brought before a stockholder meeting. These procedures may have the effect of preventing a stockholder proposal or the election of a director nominated by a stockholder from being voted upon at a stockholder meeting if the proper procedures are not followed, and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of our company.

Board Classification

Our board of directors will be divided into three classes. The directors in each class will serve for a three-year term, one class being elected each year by our stockholders. This system of electing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors. In addition, cumulative voting in the election of directors is prohibited, which means that the holders of a majority of our outstanding shares of common stock can elect all directors standing for election.

Limitation on Removal and Appointment of Directors

Our amended and restated bylaws will provide that our directors may be removed only for cause and that vacancies on our board of directors or newly created directorships resulting from an increase in the number of our directors may be filed only by a majority of the directors then in office, even though less than a quorum. These provisions will make it more difficult for both our stockholders and a potential acquirer to replace members of our board of directors or appoint additional members to our board of directors.

Super-Majority Requirements to Change Anti-Takeover Provisions

Our amended and restated certificate of incorporation and bylaws will require the approval of our board of directors or the holders of two-thirds of the outstanding shares of our common stock to amend our bylaws and certain provisions of our amended and restated certificate of incorporation, including certain of the anti-takeover provisions described above.

-147-

Choice of Forum

Our amended and restated certificate of incorporation will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine.

Delaware Anti-Takeover Statute

Upon the closing of this offering, we will be subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. In general, Section 203 prohibits a publicly held Delaware corporation from engaging, under certain circumstances, in a “business combination” with an “interested stockholder,” as those terms are defined in the DGCL, for a period of three years following the date the person became an interested stockholder unless:

•

prior to the date of the transaction, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•

at or subsequent to the date of the transaction, the business combination is approved by our board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 ²/₃% of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a business combination includes, among other things, a merger, sale of at least 10% of the corporation’s assets, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

The provisions of Delaware law and the provisions of our amended and restated certificate of incorporation and bylaws described above could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they might also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is also possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

Limitation on Liability of Officers and Directors; Indemnification of Directors and Officers

As permitted by the DGCL, our amended and restated certificate of incorporation will include a provision that eliminates the personal liability of a director for monetary damages to us or our stockholders for breach of his or her fiduciary duty as a director, except for liability for:

•

any breach of the director’s duty of loyalty to us or our stockholders;

•

any acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law;

•

any unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or

•

any transactions from which the director derived an improper personal benefit.

Our amended and restated certificate of incorporation and bylaws will require us to indemnify our directors and executive officers to the maximum extent not prohibited by the DGCL or any other applicable law and allow us to indemnify other officers, employees and other agents as set forth in the DGCL or any other applicable law.

We believe that these limitation of liability and indemnification provisions are useful to attract and retain qualified directors and officers.

Transfer Agent and Registrar

Upon the completion of this offering, the transfer agent and registrar for our common stock will be .

Market Listing

We intend to apply to list our common stock on The Nasdaq Global Market under the symbol “AURX.”

Following the demerger, we expect that CDIs representing our common stock will be listed on the Australian Securities Exchange under the symbol “ .”

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no public market for shares of our common stock. Future sales of substantial amounts of shares of common stock, including shares distributed in the Demerger (or CDIs representing those shares) and shares issued upon the exercise of options and warrants, in the public market after this offering, or the possibility or perception of these sales occurring, could adversely affect the prevailing market price for our common stock or impair our ability to raise equity capital.

We estimate that upon the completion of this offering, a total of shares of our common stock will be outstanding, assuming that shares of our common stock are distributed to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution to Alchemia Limited shareholders of one share of our common stock for every outstanding ordinary shares of Alchemia Limited. However, the actual number of shares of our common stock distributed in the Demerger will depend upon the number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger, which is expected to be , 2012, and the terms of the Demerger provide that fractional shares of our common stock that would otherwise be distributed pursuant to the Demerger will be rounded upwards to the nearest whole share. In addition, options to purchase a total of 7,265,000 ordinary shares of Alchemia Limited at exercise prices ranging from AUD$0.28 to AUD$1.725 per share (equivalent to approximately US$0.28 to US$1.718 per share based on the currency exchange rate as of June 15, 2012) were outstanding as of March 31, 2012 and any exercise of these options or any other options that Alchemia Limited may grant prior to the record date for the Demerger would increase the number of ordinary shares of Alchemia Limited outstanding as of such record date and the number of shares of our common stock distributed in the Demerger and to be outstanding immediately after this offering. As a result, the actual number of shares of our common stock that will be distributed in the Demerger and that will be outstanding immediately after this offering will be different than the number of shares we have assumed for the purposes of the discussion in this section. Each share increase (decrease) in the estimated number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger would increase (decrease) estimated the number of shares of our common stock to be issued in the Demerger and to be outstanding immediately after this offering by shares.

-150-

Of the shares of our common stock to be outstanding upon completion of this offering, all shares of common stock sold in this offering by us, including any shares sold upon exercise of the underwriters’ over-allotment option, will be freely tradable in the public market without restriction or further registration under the Securities Act, unless these shares are held by our “affiliates,” as that term is defined in Rule 144 under the Securities Act, and subject in certain cases to the lock-up agreements referred to below. In addition, additional shares of our common stock (being the estimated number of shares to be distributed in the Demerger) will be freely tradable in the public markets without restriction or further registration under the Securities Act pursuant to Section 3(a)(10) under the Securities Act, unless those shares are held by our “affiliates” as defined above, and subject in certain cases to the lock-up agreements referred to below. As a result of the lock-up agreements described below, the shares of our common stock that we estimate will be outstanding upon completion of this offering and the Demerger will be available for sale in the public markets as follows:


Date	Number of Shares Eligible for Sale in Public Market / Percent of Outstanding Stock	Comment
At the date of this prospectus		Shares sold in this offering or distributed in the Demerger
Between 90 and 180 days (subject to extension) after the date of this prospectus		Shares eligible for sale under Rule 144
After 180 days after the date of this prospectus (subject to extension) and various times thereafter		Shares eligible for sale under Rules 144 or upon expiration of lock-up agreements

As described under “Underwriting — Lock-Up Agreements,” the lock-up agreements referred to below prohibit, in general and subject to exceptions, sales of shares of our common stock for a period of 180 days after the date of this prospectus without the prior written consent of each of Leerink Swann LLC and Oppenheimer & Co. Inc. However, this 180-day period may, subject to specified exceptions, be extended by up to 34 additional days under specified circumstances. In the event of any extension, references to 180 days in the preceding table should be read to mean 180 days plus the number of days of that extension. Information in the table above is based on lock-up agreements that have been signed through , 2012.

Rule 144

In general, under Rule 144 as currently in effect, once we have been subject to public company reporting requirements of the Securities Act for at least 90 days, a person who is not deemed to have been one of our affiliates for purposes of Rule 144 under the Securities Act at any time during the three months preceding a sale and who has beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than our affiliates, is entitled to sell such shares in the public markets (subject to the lock-up agreements referred to below, if applicable) without complying with the manner of sale, volume limitation or notice provisions of Rule 144, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of any prior owner other than our affiliates, then such person is entitled to sell such shares without complying with any of the requirements of Rule 144 (subject to the lock-up agreements referred to below, if applicable).

-151-

In general, under Rule 144, as currently in effect, our affiliates or persons selling shares on behalf of our affiliates who have beneficially owned the shares proposed to be sold for at least six months are entitled to sell upon expiration of the lock-up agreements described above (if applicable), within any three-month period beginning 90 days after the effective date of the registration statement of which this prospectus is part, a number of shares that does not exceed the greater of:

•

1% of the number of shares of our common stock then outstanding, which we estimate will equal approximately shares immediately after this offering, assuming that shares of our common stock are distributed to Alchemia Limited shareholders (or a depositary on their behalf) in the Demerger, which number of shares is based on 280,617,079 ordinary shares of Alchemia Limited outstanding as of March 31, 2012 and the distribution to Alchemia Limited shareholders of one share of our common stock for every outstanding ordinary shares of Alchemia Limited. However, as discussed above, the actual number of shares of our common stock distributed in the Demerger and that will be outstanding upon completion of this offering will be different than the number of shares we have assumed for the purposes of this prospectus. Each share increase (decrease) in the estimated number of ordinary shares of Alchemia Limited outstanding as of the record date for the Demerger would increase (decrease) the estimated number of shares of our common stock to be issued in the Demerger and to be outstanding immediately after this offering by shares; or

•

the average weekly trading volume of the common stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to such sale.

Sales under Rule 144 by our “affiliates” or persons selling shares on behalf of our “affiliates” are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us.

Section 3(a)(10)

Section 3(a)(10) of the Securities Act is an exemption from registration for offers and sales of securities in specified exchange transactions, subject to certain requirements, including obtaining approval from a court or authorized governmental entity that the exchange is fair to the security holders participating in the exchange. Section 3(a)(10) generally allows a stockholder who received shares of our common stock or CDIs pursuant to a Section 3(a)(10)-exempt exchange and who is not deemed to be an “affiliate” (as defined above) of our company after the transaction, to sell these shares and CDIs without regard to Rule 144. Section 3(a)(10) also permits stockholders who are affiliates of our company to sell their Section 3(a)(10) shares and CDIs under Rule 144. We expect that the shares of our common stock distributed in the Demerger will be entitled to the exemption provided by Section 3(a)(10), subject to the foregoing limitation applicable to affiliates. Lock-up agreements referred to below limit the ability of certain holders to sell their Section 3(a)(10) shares.

Lock-Up Agreements

We and our officers, directors, and certain Alchemia Limited shareholders who will receive CDIs or shares of our common stock in the Demerger have entered into lock-up agreements that, in general and subject to exceptions, prohibit us from issuing or selling shares of our common stock and prohibit those persons from selling or otherwise transferring their shares of common stock or CDIs for a period of 180 days after the date of this prospectus, subject to extension by up to 34 additional days under specified circumstances and subject to specified exceptions, without the prior written consent of Leerink Swann LLC and Oppenheimer & Co. Inc. For more information see “Underwriting — Lock-Up Agreements” below.

Warrants

In connection with the Placement in November and December of 2011 of ordinary shares of Alchemia Limited, we are required, contingent on completion of this offering, to issue Warrants to the investors entitling them to acquire shares of our common stock. The exercise price of the Warrants will be equal to 130% of the volume weighted average price of our common stock for the 60 trading days immediately following the listing of our common stock on the Nasdaq Global Market (we sometimes refer to such volume weighted average price for such period as the Average Trading Price). The number of shares of our common stock, or the Warrant Shares, that will be issuable upon exercise of those Warrants will be equal to the quotient obtained by dividing (1) AUD$8,073,000 (equivalent to approximately US$8,066,542 based on the average of the currency exchange rates on November 11, 2011 and December 21, 2011, the dates on which the private placement closed) by (2) 130% of the Average Trading Price. Assuming an Average Trading Price of US$ per share (the midpoint of the estimated price range set forth on the cover page of this preliminary prospectus) and an exchange rate of US dollars for one Australian dollar, approximately Warrant Shares would be issuable upon exercise of the Warrants at an exercise price of approximately US$ per share. However, because the number of Warrant Shares and exercise price both depend upon the actual Average Trading Price following this offering and the number of Warrant Shares also depends upon the exchange rate between U.S. dollars and Australian dollars, the actual number of Warrant Shares and the actual exercise price will likely differ from the numbers we have assumed for purposes of this preliminary prospectus. See “Prospectus Summary — The Offering “ for an analysis that shows how changes in the Average Trading Price change the number of Warrant Shares issuable upon exercise of the Warrant and the exercise price of the Warrant and how changes in the currency exchange rate affect the number of Warrant Shares issuable upon such exercise. In addition, the number of Warrant Shares and/or the exercise price are subject to adjustment pursuant to the terms of the Warrants, including in the event of stock splits, stock combinations and similar events as well as in the event of dividends or other distributions on our shares of common stock. The Warrants and the shares of our common stock issued upon exercise of the Warrants will be restricted securities under the Securities Act and may be sold pursuant to Rule 144 or another exemption from registration.

Registration Statements on Form S-8

In connection with this offering, we intend to grant stock options to purchase shares of our common stock with exercise prices that will be equal to the initial offering price of our common stock sold in this offering, pursuant to our 2012 Equity Incentive Plan. After giving effect to the issuance of those stock options, additional shares of our common stock will be available for future award under our 2012 Equity Incentive Plan, plus automatic annual increases in the number of shares available for future award under that plan, all as described under “Executive Compensation — 2012 Equity Incentive Plan” above. Shares of common stock issuable upon exercise of those options or pursuant to our 2012 Equity Incentive Plan will be eligible for resale under the provisions of Rule 144, subject to compliance with the terms of that rule and any applicable lock-up agreements.

In addition, we intend to file a registration statement on Form S-8 under the Securities Act to register the shares of common stock issuable or reserved for issuance under stock option or equity incentive plans. We expect to file this registration statement shortly after this offering. Shares covered by this registration statement will be eligible for sale in the public market upon the expiration or release from the terms of the lock-up agreements, if applicable, and subject to vesting of such shares.

Sales on Behalf of Ineligible Foreign Shareholders

Based on Alchemia Limited’s stock records, we believe that certain Alchemia Limited shareholders reside or are located in jurisdictions where, as a result of local securities laws, they will not be permitted to receive shares of our common stock or CDIs distributed in the Demerger (we sometimes refer to these shareholders as

-153-

ineligible foreign shareholders). Accordingly, CDIs or shares of our common stock that would otherwise be distributed in the Demerger to these ineligible foreign shareholders will instead be delivered to a sales facilities agent, who will then sell those CDIs or shares of our common stock in the open market, which may include sales on the Australian Securities Exchange or the Nasdaq Global Market, and remit the proceeds to the ineligible foreign shareholders. We expect that these sales will be made shortly after the completion of this offering. See “Risk Factors — Future sales of shares of our common stock could cause the market price of our common stock to decline. This risk is heightened by the fact that the shares sold in this offering, and the shares of our common stock distributed in the Demerger and CDIs representing those shares will be freely tradable in the public markets immediately upon completion of this offering, and a number of those shares of our common stock and the CDIs will not be subject to lock-up agreements.”

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences applicable to non-U.S. holders (as defined below) of the acquisition, ownership and disposition of our common stock sold pursuant to this offering. This discussion is not a complete analysis of all the potential U.S. federal income tax consequences relating thereto, nor does it address any tax consequences arising under any state, local or non-U.S. tax laws, the U.S. federal estate tax or gift tax rules or any other U.S. federal tax laws. This discussion is based on the Code, Treasury Regulations promulgated thereunder, judicial decisions and published rulings and administrative pronouncements of the Internal Revenue Service, or IRS, all as in effect as of the date of this prospectus. These authorities may change, possibly retroactively, resulting in U.S. federal income tax consequences different from those discussed below.

This discussion is limited to non-U.S. holders who purchase our common stock pursuant to this offering and who hold our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax considerations that may be relevant to a particular holder in light of that holder’s particular circumstances. This discussion also does not consider any specific facts or circumstances that may be relevant to holders subject to special rules under the U.S. federal income tax laws, including, without limitation, persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), certain former citizens or long-term residents of the United States, an integral part or controlled entity of a foreign sovereign, partnerships and other pass-through entities, real estate investment trusts, regulated investment companies, “controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid U.S. federal income tax, banks, financial institutions, insurance companies, brokers, dealers or traders in securities, commodities or currencies, tax-exempt organizations, tax-qualified retirement plans, persons subject to the alternative minimum tax, persons holding our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment or persons deemed to sell our common stock under the constructive sale provisions of the Code.

If a partnership (or other entity taxed as a partnership for U.S. federal income tax purposes) holds our common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that hold our common stock and partners in such partnerships are urged to consult their tax advisors regarding the specific U.S. federal income tax consequences to them of acquiring, owning or disposing of our common stock.

PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE PARTICULAR U.S. FEDERAL INCOME TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING AND DISPOSING OF OUR COMMON STOCK WITH RESPECT TO THEIR PARTICULAR SITUATIONS, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER ANY STATE, LOCAL OR NON-U.S. TAX LAWS, THE U.S. FEDERAL ESTATE OR GIFT TAX RULES, ANY OTHER U.S. FEDERAL TAX LAWS AND ANY APPLICABLE TAX TREATY.

Definition of Non-U.S. Holder

For purposes of this discussion, a non-U.S. holder is any beneficial owner of our common stock that is not a “U.S. person” or a partnership for U.S. federal income tax purposes. A U.S. person is any of the following:

•

an individual citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

-155-

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust (i) if a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust or (ii) that has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person for U.S. federal income tax purposes.

Distributions on Our Common Stock

As described in the section entitled “Dividend Policy,” we do not anticipate paying cash dividends on our common stock. If, however, we make distributions of cash or property (other than certain pro rata distributions of shares of our common stock) on our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and will first be applied against and reduce a non-U.S. holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as gain from the sale of stock and will be treated as described under the section entitled “Gain on Sale or Disposition of Our Common Stock” below.

Dividends paid to a non-U.S. holder of our common stock that are not effectively connected with a U.S. trade or business conducted by such holder generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends, or such lower rate specified by an applicable tax treaty. To receive the benefit of a reduced treaty rate, a non-U.S. holder must timely furnish to us or our paying agent a valid IRS Form W-8BEN (or applicable successor form) certifying such holder’s qualification for the reduced rate. This certification must be provided to us or our paying agent prior to the payment of dividends and must be updated periodically. If the non-U.S. holder holds the stock through a financial institution or other agent acting on the non-U.S. holder’s behalf, the non-U.S. holder will be required to provide appropriate documentation to the agent, who then will be required to provide certification to us or our paying agent, either directly or through other intermediaries. Non-U.S. holders that do not timely provide us or our paying agent with the required certification, but that qualify for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders should consult their tax advisors regarding possible entitlement to benefits under a tax treaty.

If a non-U.S. holder holds our common stock in connection with the conduct of a trade or business in the United States, and dividends paid on the common stock are effectively connected with such non-U.S. holder’s U.S. trade or business (and, if required by an applicable tax treaty, attributable to a permanent establishment maintained by the non-U.S. holder in the United States), dividends paid to the non-U.S. holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the non-U.S. holder must furnish to us or our paying agent a valid IRS Form W-8ECI (or applicable successor form), certifying that the dividends are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States.

Any dividends paid on our common stock that are effectively connected with a non-U.S. holder’s U.S. trade or business (and, if required by an applicable tax treaty, attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be subject to graduated U.S. federal income tax rates, net of deductions and credits, in the same manner as if such holder were a U.S. person. Dividends that are effectively connected with the conduct of a U.S. trade or business and paid to a non-U.S. holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable tax treaty). Non-U.S. holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

-156-

Gain on Sale or Disposition of Our Common Stock

Subject to the discussions below regarding backup withholding and legislation relating to foreign accounts, a non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or disposition of our common stock unless:

•

the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States and, if required by an applicable tax treaty, attributable to a permanent establishment maintained by the non-U.S. holder in the United States;

•

the non-U.S. holder is a nonresident alien individual present in the United States for a period or periods of 183 days or more in the aggregate during the taxable year of the sale or disposition and certain other requirements are met; or

•

our common stock constitutes a U.S. real property interest by reason of our status as a U.S. real property holding corporation, or USRPHC, for U.S. federal income tax purposes during the relevant statutory period.

The gain described in the first bullet point above generally will be subject to U.S. federal income tax at graduated tax rates on a net income basis in the same manner as if such non-U.S. holder were a U.S. person. A non-U.S. holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable tax treaty). Non-U.S. holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Gain described in the second bullet point above generally will be subject to U.S. federal income tax at a flat 30% rate (or such a lower rate specified by an applicable income tax treaty), but may be offset by U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States), provided that the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we would be a USRPHC if the fair market value of our interests in U.S. real property equals or exceeds 50% of the aggregate fair market value of our worldwide real property interests and our other assets used or held for use in a trade or business. We believe that we currently are not, and we do not anticipate becoming, a USRPHC for U.S. federal income tax purposes. Because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property interests relative to the fair market value of our non-U.S. real property interests and other trade or business assets, however, there can be no assurance that we will not become a USRPHC in the future. In the event we do become a USRPHC, as long as our common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, our common stock will be treated as a U.S. real property interest only with respect to a non-U.S. holder that actually or constructively holds more than 5% of our common stock at any time during the shorter of the five-year period preceding the date of disposition or the non-U.S. holder’s holding period. We expect our common stock to be “regularly traded” on an established securities market, although there can be no assurance that it will be so traded. If gain on the sale or other taxable disposition of our stock were subject to taxation under the third bullet point above, the non-U.S. holder would be subject to regular U.S. federal income tax with respect to such gain in generally the same manner as a U.S. person.

Information Reporting and Backup Withholding

Generally, we must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such non-U.S. holder, the name and address of the non-U.S. holder, and the amount of any tax withheld with respect to those dividends. This information also may be made available under a specific treaty or agreement with the tax authorities of the country in which the non-U.S. holder resides or is established. Under certain

-157-

circumstances, the Code imposes an information reporting and a backup withholding obligation (currently at a rate of 28% but scheduled to increase to 31% for payments made after December 31, 2012) on certain reportable payments such as dividends paid on or the gross proceeds from disposition of our common stock. Backup withholding generally will not, however, apply to payments of dividends to a non-U.S. holder of our common stock provided the non-U.S. holder furnishes to us or our paying agent the required certification as to its non-U.S. status, such as by providing a valid IRS Form W-8BEN or W-8ECI, or otherwise establishes an exemption. Notwithstanding the foregoing, backup withholding may apply if either we or our paying agent has actual knowledge, or reason to know, that the holder is a U.S. person that is not an exempt recipient.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Legislation Relating to Foreign Accounts

Legislation enacted in 2010 may impose withholding taxes on certain types of payments made to “foreign financial institutions” (as specially defined under these rules) and certain other non–U.S. entities. Under this legislation, the failure to comply with additional certification, information reporting and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds to foreign intermediaries and certain non-U.S. holders. The legislation imposes a 30% withholding tax on dividends on, or gross proceeds from the sale or other disposition of, our common stock paid to a foreign financial institution or to a foreign non-financial entity, unless (i) the foreign financial institution undertakes certain diligence and reporting obligations or (ii) the foreign non-financial entity either certifies it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner. If the payee is a foreign financial institution, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. Under certain transition rules, any obligation to withhold under the legislation with respect to dividends on our common stock will not begin until January 1, 2014 and with respect to the gross proceeds of a sale or other disposition of our common stock will not begin until January 1, 2015. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Prospective investors should consult their tax advisors regarding the possible implications of this legislation on their investment in our common stock.

The underwriters are committed to purchase all the shares of common stock offered by us if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated. The underwriters are not obligated to purchase the shares of common stock covered by the underwriters’ over-allotment option described below.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of customary closing documents. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Over-Allotment Option

We have granted the underwriters an option to purchase up to additional shares of common stock at the public offering price appearing on the cover page of this prospectus, less underwriting discounts and commissions. The underwriters may exercise this option for 30 days from the date of this prospectus solely to cover sales of shares of common stock by the underwriters in excess of the total number of shares set forth in the table above. If any shares are purchased pursuant to this over-allotment option, the underwriters will purchase their pro rata portions of the additional shares in approximately the same respective proportions as shown in the table above. If any of these additional shares are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares reflected in the table above are being offered.

Discounts and Commissions

The underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $ per share. The underwriters may allow, and the dealers may reallow, a discount not in excess of $ per share to other dealers. After the initial offering of the shares, the public offering price and other selling terms may be changed by the representatives.

The following table shows the public offering price, underwriting discounts and commissions and proceeds before expenses to us.

Initial Public Offering Pricing

Prior to this offering, there has been no public market for our common stock. The initial public offering price will be negotiated between us and the representatives. The factors considered in these negotiations may include, among others:

•

the prospects for our company and the industry in which we operate;

•

our past and present financial and operating performance;

•

financial and operating information and market valuations of publicly traded companies engaged in activities similar to ours;

•

an assessment of our management;

•

the prevailing conditions of U.S. securities markets at the time of this offering; and

•

other factors deemed relevant.

The estimated initial public offering price range set forth on the cover of this preliminary prospectus is subject to change as a result of market conditions and other factors.

Lock-Up Agreements

We and our officers, directors, and certain Alchemia Limited shareholders who will receive CDIs or shares of our common stock in the Demerger have agreed with the underwriters, subject to certain exceptions, not to dispose of any of our shares of common stock, CDIs or securities convertible into or exercisable or exchangeable for shares of our common stock or CDIs during the period from the date of this prospectus continuing through the date 180 days after the date of this prospectus, except with the prior written consent of Leerink Swann LLC and Oppenheimer & Co. Inc. The 180-day restricted period described in the preceding sentence will be automatically extended if: (1) during the last 17 days of the 180-day restricted period, we issue an earnings release or announce material news or a material event; or (2) prior to the expiration of the 180-day restricted period, we announce that we will release earnings results during the 15-day period following the last day of the 180-day period, in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement or the material news or material event.

Leerink Swann LLC and Oppenheimer & Co. Inc., in their sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time without

-160-

notice. When determining whether or not to release common stock or other securities from the lock-up agreements, Leerink Swann LLC and Oppenheimer & Co. Inc. may consider, among other factors, the reasons for requesting the release, the number of shares of common stock and other securities for which the release is being requested and market conditions at the time.

Indemnification

We and Alchemia Oncology have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

The Nasdaq Global Market Listing

We are applying to have our common stock listed on the Nasdaq Global Market under the symbol “AURX.”

Following the demerger, we expect that depositary shares representing our common stock will be listed on the Australian Securities Exchange under the symbol “ ” in the form of CHESS Depository Interests that will represent of a share of our common stock.

Price Stabilization, Short Positions and Penalty Bids

In order to facilitate the offering of our common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock. In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional shares of common stock in the offering. The underwriters may close out any covered short position by either exercising their over-allotment option or purchasing shares of common stock in the open market. In determining the source of shares of common stock to close out the covered short position, the underwriters may consider, among other things, the price of shares available for purchase in the open market as compared with the price at which they may purchase shares through the over-allotment option. “Naked” short sales are sales made in an amount in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose penalty bids on members of the underwriting syndicate. Penalty bids permit the representatives of the underwriters to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transactions to cover syndicate short positions.

These syndicate covering transactions, stabilizing transactions and penalty bids, may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the market price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the Nasdaq Global Market or otherwise. However, the underwriters will not undertake any of these transactions with respect to the CDIs representing shares of our common stock, which CDIs will be listed on the Australian Securities Exchange.

-161-

Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above, if commenced, may have on the price of our common stock. In addition, neither we nor the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Offer, Sale and Distribution of Shares

A prospectus in electronic format may be made available on the websites maintained by one or more underwriters or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares of common stock to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations. Other than the prospectus in electronic format, the information on the websites of the underwriters and any selling group members and any information contained in any other website maintained by any of the underwriters and any selling group members is not part of this prospectus or the registration statement of which this prospectus forms a part.

Discretionary Sales

The underwriters have informed us that they do not intend to confirm sales to discretionary accounts that exceed 5% of the total number of shares offered by them.

Stamp Taxes

If you purchase shares of common stock offered in this prospectus, you may be required to pay stamp taxes and other charges under the laws and practices of the country or other jurisdiction of purchase, in addition to the offering price listed on the cover page of this prospectus.

Other Relationships

The underwriters and their affiliates may in the future provide investment banking, commercial banking and advisory services to us from time to time for which they expect to receive customary compensation and expense reimbursement.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Audeo Oncology, Inc.

We have audited the accompanying consolidated balance sheets of Audeo Oncology, Inc. (a development stage company) (the “Company”) as of June 30, 2010 and 2011, and the related consolidated statements of operations and comprehensive loss, changes in stockholders’ deficit, and cash flows for each of the two years in the period ended June 30, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Audeo Oncology, Inc. (a development stage company) at June 30, 2010 and 2011, and the consolidated results of its operations and comprehensive loss and its cash flows for each of the two years in the period ended June 30, 2011, in conformity with U.S. generally accepted accounting principles.
