This Annual Report on Form 10-K for the year ended December 31, 2021 (this “Report”) contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve risks and uncertainties. Purchasers of any of the shares of common stock of ProLung, Inc. are cautioned that our actual results will differ (and may differ significantly) from the results discussed in the forward-looking statements. The reader is also encouraged to review other filings made by us with the Securities and Exchange Commission (the “SEC”) describing other factors that may affect future results.

In this filing, ProLung, Inc. is referred to as “ProLung,” “IONIQ Sciences” or “IONIQ” in addition to as the “Company” and versions of “we” or “us.” On May 27, 2020, ProLung, Inc. announced we had filed a dba IONIQ Sciences (“IONIQ” or the “Company”) to reflect our expanded early cancer detection strategy. Current and all granted trademarks include IONIQ Sciences®, IONIQ Science®, IONIQ Test®, IONIQ Screen® and ProLung®. Any other trademarks and service marks used in this Report are the property of their respective holders.

Item 1. Business

We are a medical technology company with a mission to dramatically improve the cancer landscape with a modern solution for the early detection of multiple cancers thereby expanding the therapeutic window, significantly improving survivability, and reducing the cost of healthcare. One in two Americans will be diagnosed with cancer during their lifetime and one in five will die. Clinical literature shows that early detection can save lives and money. We operate at the confluence of our Electrical Impedance Analytics (EIA) technology or bioimpedance and artificial intelligence (AI). We are developing an advanced multi-cancer screening technology for early detection of multipole cancers that may expand the therapeutic window, dramatically improve survivability and reduce the cost of healthcare. We have active projects in lung, breast and gastro-intestinal (GI) cancers. The first planned product utilizing our proprietary analytic platform, the IONIQ ProLung Test™ for lung cancer, has been designated a Breakthrough Device by the U.S. FDA in February 2020. We submitted our de novo application to the U.S. FDA in February 2022. We remain fully-committed to gaining U.S. FDA regulatory de novo clearance and subsequently commercializing the IONIQ ProLung Test for lung cancer.

Our non-invasive, rapid and radiation-free IONIQ ProLung Test developed to assess the risk of malignancy in lung nodules found in the chest by a Computed Tomography “CT” scan, which is currently the primary method used in the United States (“US”) for screening lung cancer. Lung cancer is the leading cause of cancer death in the US and the world according to American Cancer Society and World Health Organization. Earlier detection makes a substantial improvement in survival in individuals at high risk of lung cancer. Timely identification of malignancy is essential for patients and their families. Currently, patients often wait from three months to three and one-half years to have the risk of malignancy assessed through periodic CT scan surveillance. Until malignancy is determined to be likely, invasive biopsy and treatment are typically delayed. Current statistics reflect an average 17% survival rate at five years for those diagnosed with lung cancer.

We believe the IONIQ ProLung Test, in conjunction with the discovery of a nodule by CT scan, provides a more rapid assessment of the risk of malignancy, which must be determined prior to biopsy. Since a lung biopsy is invasive and may require life threatening thoracic surgery, physicians, patients, and insurance companies typically delay biopsy and therapy until the risk of malignancy outweighs the risk of further diagnostic procedures. For these patients, the delay can reduce the time available to treat the tumor and may cause sustained emotional trauma.

The IONIQ ProLung Test is designed to enable the practitioner to promptly assess the risk of malignancy in patients with lung nodules. The IONIQ ProLung Test utilizes mass-averaging bioimpedance technology or Electrical Impedance Analytics (EIA). Mass-averaging bioimpedance technology involves a sequential scanning process that measures significant differences in electrical conductance between cancerous and benign tissue. We plan to introduce the IONIQ ProLung Test to the market as a standard predictive analytic test, without the need for transmission of a physical sample or specimen to a lab for analysis.

The IONIQ ProLung Test acquires bioimpedance measurement data by means of a patented probe and disposable diaphoretic or EKG-type electrodes placed on the patient’s back and arms. The IONIQ ProLung Test registers and evaluates measurement data derived from numerous pathways through the chest and is processed by a predictive analytic algorithm. The results are summarized in a report that can be used by the physician, in concert with other risk factors such as nodule size, family history, smoking history and gender, to evaluate patients with nodules. The IONIQ ProLung Test requires minimal preparation and can be completed in 20 minutes. Most importantly, it guides or informs the physician’s decision making without the time consuming, expensive and watchful waiting period. We believe the IONIQ ProLung Test provides considerable cost savings when compared with today’s status quo of patients undergoing repeated CT imaging studies and potentially unnecessary surgery.

ProLung dba IONIQ Sciences owns the intellectual property and established the clinical research plan for the IONIQ ProLung Test. Beginning in 2005, we embarked on clinical research which revealed the potential of our technology. In 2011, our research demonstrated the utility of the IONIQ ProLung Test in lung cancer patients. To date, more than 1,200 subjects have been tested using the IONIQ ProLung Test at IONIQ’s headquarters and in major cancer centers. If our de novo FDA clearance is granted, of which there can be no assurance, we plan to transition the hospitals that participated in our clinical trials to commercial placements of the IONIQ ProLung Test System and consumable IONIQ ProLunt Test kit.

In the US, the push for early detection of lung cancer was greatly accelerated in 2013 and again most recently in 2020. Recognizing the dismal rate of lung cancer survival in the US, and the potential value of early detection, US guidelines were established for lung cancer CT screening. The guidelines provided for CT screening for lung cancer in asymptomatic adults aged 55 to 80 who have a 30 pack-year history of smoking and who currently smoke or have quit smoking in the past 15 years. This demographic group addresses a substantial portion of individuals of high risk of lung cancer. In 2020, the guidelines were expanded effectively doubling the population covered. The US health care industry has generally recognized the need for technologies that will provide for earlier detection of cancers at a lower cost. Genetic biomarkers, protein panels, and breath analysis, among others, are in various stages of development. The IONIQ ProLung Test is the first bioconductive technology that has been developed for the risk stratification of lung cancer. In February 2015, the US Centers for Medicare & Medicaid Services (CMS) announced its coverage of lung cancer screening by CT. This newly reimbursed screening procedure increased the number of individuals with suspicious lung nodules who may be candidates for the IONIQ ProLung Test.

With the arrival of lung cancer screening recommendations, the large US market and government-backed reimbursement represent near term opportunities to accelerate diagnosis and treatment of lung cancer while reducing invasive biopsies and costs. We made US clearance and recognition of the IONIQ ProLung Test a major priority, targeting lung cancer risk stratification and reducing time to treatment. We intend to seek government-backed reimbursement after FDA clearance. We are also interested in improving the cost of diagnosis and treatment with capitated providers. We believe the IONIQ ProLung Test can be offered at a fraction of the cost of current standard of care, which is repeat periodic imaging studies.

In May 2013, we achieved an important validation of our IONIQ ProLung Test by receiving the “CE” mark in Europe. This certification verifies that the IONIQ ProLung Test meets the regulatory requirements for the marketing and sale of the IONIQ ProLung Test in the European Economic Area and European Free Trade Association Countries representing approximately 513 million individuals and 28-member states. Our European clinical research includes testing more than 154 patients in Italy, Switzerland and Germany. We intend to seek European reimbursement approval and accelerate our marketing in Europe following receipt of US Food and Drug Administration, (“FDA”) market clearance. We believe CT screening is likely to be implemented in Europe following the completion of several lung cancer screening trials already underway.

In September of 2013, we applied for marketing clearance under Section 510(k) from the FDA. After review of the 510(k) application, the FDA issued a letter to ProLung in May 2014 indicating that the FDA believed that our 510(k) would likely be found “Not Substantially Equivalent” to a legally marketed predicate device and the FDA believed ProLung may be suitable for de novo classification. Subsequently, we submitted a de novo petition in August of 2014. In February 2015, we received a “substantive review” from the FDA requesting additional information, regarding the risk classification of the test, the study design and study analysis. We held various meetings with the FDA and agreed to complete and include an additional clinical study, which was already underway. Subsequently, our IONIQ ProLung Test has been designated a Breakthrough Device by the U.S. FDA in February 2020 based on the clinical trial results from PLW-216. In February 2022, we submitted our de novo application to the U.S. FDA, which we believe addresses the remaining issues previously identified by the FDA.

We have developed the quality management system as well as supply chain and the ability to fully manufacture the entire IONIQ System in our own Salt Lake City facility. We have received ISO 13485 and other clearances and made certain refinements to the intellectual property that will further our capabilities, especially the development of the underlying predictive analytic algorithm and refinements to various software and physical components. We have repatedly expanded our intellectual property portfolio, completed the development of the IONIQ ProLung Test and manufacturing of the IONIQ System and embarked upon clinical trials to provide validation to the medical community.

The results of the clinical trial of 420 patients from 15 cancer and medical centers across the US, named PL-208, was published in early 2019. The results of another clinical trial of 486 patients from four cancer and medical centers in China, named PLW-216, was published in late 2019. We believe the results are more solid indicators that our IONIQ ProLung Test is capable of identifying a signal that can be used to indicate the risk of malignancy in pulmonary nodules by non-invasively measuring their bioconductance biomarker. With the conclusion of these Studies, the IONIQ Team is eager to turn its focus to validating a number of already identified hardware, software and data collection improvements designed to strengthen our algorithm’s performance and support a future submission to the FDA. The Company is also in the midst of evaluating a number of potential strategic partnerships to accelerate our development by expanding our financial and support network.

In late 2018, we announced final results of our Repeatability Study, named PL-209. The repeatability study enrolled sixty subjects, 30 male and 30 female, half of each gender with a body mass index (BMI) of 30 or more, and half with a BMI of 28 or less. Each subject was scanned twice on Day One and twice on Day Two. All scans were done by the same operator on the same IONIQ System. Fifty-nine subjects produced evaluable data. Four models (algorithms) were tested. The study was conducted by ProLung. Study objectives included quantifying the effects of gender, body mass index (BMI), day-to-day subject variability and variability of a single device when volume-averaged thoracic bioconductance was measured with the IONIQ ProLung Test. The repeatability study addressed several questions regarding use of the IONIQ ProLung Test. One significant limitation of this study is that no subjects with known pulmonary nodules or malignancy were enrolled. It is unknown whether pulmonary nodules or malignancy affect the repeatability of the IONIQ ProLung Test. While the study showed statistically significant variability of approximately 2% when testing the same subject twice on the same day, the clinical impact of this finding is unknown because it is not anticipated that patients will receive a second test on the same day in clinical use. While we note significant day-to-day variability when using an earlier model (the algorithm used in the Johns Hopkins Study, Journal of Thoracic Oncology, 2012), repeatability is markedly improved when using a more refined model.

In late 2019, we announced the final results of our Validation Study, named PLW-216. The validation study enrolled 486 subjects from four leading cancer and medical centers in China. The results were 84% sensitivity and 73% specificity in the 418 subjects included in the analysis.

In February 2020, the FDA designated the IONIQ ProLung Test a Breakthrough Device. Through the Breakthrough Device program, the FDA will provide ProLung with expedited reviews and the Centers for Medicare & Medicaid Services (CMS). This is not a marketing clearance.

PL-209 Study Conclusions

1.	Same-day variability is statistically significant (average second score is 0.0214 points lower), but the clinical impact of this finding is unclear.
2.	Day-to-day variability is impacted by the model (algorithm) chosen. One particular model with age (model 1b+age) has an ICC=0.958, indicating it is very repeatable.
3.	Gender and BMI do not affect test performance.
4.	Average test time is 18.5 minutes, with a range of 15-24 minutes.
5.	The test is well tolerated and agreeable to test subjects.

PL-208 Study (2012-2019)

Three Validation studies have been completed for the IONIQ ProLung Test. The first is PL-208 which enrolled 420 patients across 15 US centers (ID: NCT01566682). This study was two-phased, with a 200-patient open-labelled training set to test and optimize an algorithm, followed by testing of the optimized algorithm on the diagnosis-blinded 174-patient validation set. Forty-six (46) subjects (11%) were excluded for being lost to follow up or having an inconclusive diagnosis, missing or inadequate device data. The predictive algorithm utilized the patient’s bioconductance measurements coupled with the patient’s age and a binary cut-off point of 0.5 was chosen to distinguish between high and low likelihood of cancer. The algorithm was locked and applied to a blinded validation set of 174 patients and yielded a Sensitivity of 69% Specificity of 49%, Positive Predictive Value (PPV) of 70%, Negative Predictive Value (NPV) of 47% and overall Accuracy of 61%.

PLW-208 Study (2015-2016)

The second validation trial (PLW-208) was completed by the Company’s licensor (ProLung Wuxi). This study enrolled 138 subjects at 2 centers in China. This study was similar in design to the US PL-208 Study and obtained a Sensitivity of 77%, Specificity of 60%, PPV of 82%, NPV of 41% and an Accuracy of 73%. In reviewing this study, the Sponsor determined that test method and operator training needed to be improved to obtain better results.

PLW-216 Study (2017-2019)

Ultimately, the Study Sponsor (ProLung Wuxi) improved the device operator training, test method and device predictive algorithm. The Sponsor concluded the PLW-208 Study and initiated PLW-216, utilizing improved training, test method and a modified locked predictive algorithm. This PLW-216 Study was a single-phase validation study whereby the predictive algorithm was locked prior to the first patient being enrolled and the IONIQ ProLung Test results were provided to site investigators prior to knowing the subject’s actual diagnosis. The PLW-216 Study enrolled 486 subjects in China at 4 centers led by Dr. Bai, the Chair of the Chinese Alliance against lung Cancer and Director of the Shanghai Respiratory Research Institute (ID: NCT 02726633, registration No 20170226). The Validation Study demonstrated improved performance yielding a Sensitivity of 84% Specificity of 73%, Positive Predictive Value (PPV) of 78%, Negative Predictive Value (NPV) of 80% and overall Accuracy of 79% from the US Study PL-208 (ID NCT0156668). This performance is comparable to other diagnostic cancer devices such as Mammogram (~sensitivity of 75%, specificity of 71%) and was demonstrated in a large sample size of 418 subjects included in the final analysis.

PL-210 - ProLung Test Measurement Collection Protocols for Label Expansion (Ongoing NCT04134520)

The purpose of this Study is to identify and test different data collection methods to determine which approaches may be useful in evaluation additional cancers to lung cancer (including breast cancer) and improve the ProLung Testing procedure. Once this Study is complete, the Sponsor plans to evaluate these improvements in future follow up cancer validation studies that will assess device accuracy using the new measurement collection methods.

Lung Cancer Market Summary

According to the American Cancer Society (“ACS”), lung cancer is the leading cause of cancer death among both men and women in the US; about one out of four cancer deaths in the US are from lung cancer. The ACS estimates that in 2017 more people in the United States will die of lung cancer than of colon, breast, and prostate cancers combined.

According to the World Health Organization (“WHO”), lung cancer is the most common cause of death from cancer worldwide and is estimated to be responsible for nearly one in five cancer related deaths. The overall ratio of mortality to incidence is 87%. Each year there are over 1.8 million new cases of lung cancer worldwide, as well as nearly 1.6 million deaths. The lifetime chance of developing lung cancer is 1:17 in women and 1:14 in men.

Until recently, asymptomatic lung cancer was detected only incidentally when looking for something else. Currently, a lung cancer screen now reimbursed by Medicare, is performed by low-dose computed tomography. This has led to a dramatic increase in number of individuals with lung nodules detected, which is intensifying the need for a risk stratification test such as the IONIQ ProLung Test.

Lung cancer patients face median five-year survival rates of only 17% (compared to 89% for breast cancer and 98% for prostate cancer). Survival rates of lung cancer lags behind that of other cancer rates due to a lack of early and effective detection, and a challenging biopsy. A significant amount of time is required to assess the risk under current guidelines. Should innovation reduce the time required for assessing the risk of malignancy, lung cancer mortality could approach that of other cancer rates. In those instances when lung cancer was detected in its earliest stage, the five-year survival improves to 80% or approximately an improvement of five times.

Direct & Indirect

Symptomatic:

Each year approximately 225,500 people are diagnosed with lung cancer and approximately 90 percent of lung cancer patients are symptomatic at presentation (ACS, 2022).

Lung Cancer Screening:

Given the size of the US market and the progression of CT scan use in early detection, clearance and acceptance of the IONIQ ProLung Test in the US is the major priority. The CDC estimates that there are 94 million Americans at risk of lung cancer (which includes current and former smokers). In the National Lung Cancer Screening Trial of 53,454 patients, approximately 24% of the CT scans performed were positive revealing a lung nodule suspicious for lung cancer that required follow-up. CT screening was recommended by the US Preventive Services Task Force on December 31, 2013, and Medicare began to pay for lung cancer screening on February 5, 2016. Based on these estimates, if the approximately 94 million Americans at risk for lung cancer received a low dose CT screen approximately 24% (or 23 million) Americans may reveal lung nodules requiring follow up. We believe these patients would be eligible to receive the IONIQ ProLung Test.

European Market

IONIQ Sciences plans to utilize its CE mark in conjunction with US marketing clearance in the European Union and European Free Trade Association Countries which represents approximately 513 million individuals and 28-member states. Europe has some of the highest smoking prevalence of any region in the world which has led to a high incidence of lung cancer. In 2012, the World Health Organization estimated that 268,000 individuals died from lung cancer and that more than 313,000 cases were diagnosed in the European Union.

It is estimated that 28% of Europeans smoke and approximately 133 million individuals are at high-risk of lung cancer. Applying the US rates in the published National Lung Screening Trial (2011), over 30 million of these individuals are estimated to have an indeterminate lung nodule and require follow-up to determine the risk of malignancy. As the number of individuals with indeterminate lung nodules continues to increase in Europe, risk stratification tools such as the IONIQ ProLung Test are needed to close the gap between discovery of a nodule and the determination of malignancy.

China Market

According to the World Health Organization, the number of smokers in China is steadily growing and increasing at higher rates than any other world region. One in three of the world’s cigarettes is smoked in China. The average Chinese smoker consumes 22 cigarettes per day. This is nearly a 50% increase from 1980. Overall, more cigarettes are smoked in China than in the next top 29 cigarette-consuming countries combined. Lung cancer is epidemic in China with 653,000 cases in 2012 and an estimated 597,000 deaths.

The government’s smoking cessation campaign and interventions are poorly funded and weakly enforced, and certain provincial governments are somewhat dependent upon state-owned tobacco sales and taxation. However, China’s Government is collaborating with pulmonology and radiology leadership to study low-dose CT screening for earlier detection of lung cancer. The government has also sponsored economic studies to investigate the reimbursement of lung cancer screening in the health insurance system.

As the number of individuals with indeterminate lung nodules continues to increase in China, risk stratification tools, such as the IONIQ ProLung Test will be needed to close the gap between discovery of a nodule and the determination of malignancy. This clinical need for risk stratification may be multiplied if a lung cancer screening program is implemented in the Chinese healthcare system.

Competition

The development and commercialization of new products to improve the accuracy and efficiency of risk stratification of lung cancer is competitive, and we expect considerable competition from major medical device companies, laboratory biomarker tests, and academic institutions that are conducting research in lung cancer. Extensive research and financial resources have been invested in the discovery and development of new lung cancer detection tests. Potential competing technologies include, but are not limited to, breath markers, sputum cytology, DNA-related markers, blood markers, radiography and CT imaging.

The timing of market introduction of some of our potential products or of competitors’ products may be an important competitive factor. We believe the speed with which we can develop products, complete clinical trials and clearance processes, and supply commercial quantities to market are important competitive factors. We expect that competition among products approved for sale will be based on various factors including product efficacy, safety, reliability, availability, price, reimbursement, and patent position. We believe that our IONIQ ProLung Test is superior or equivalent to existing alternatives in all of these areas, other than availability (in the US due to lack of FDA clearance) and reimbursement.

Business

IONIQ ProLung Test

The IONIQ ProLung Test is comprised of the following two components:

	●	IONIQ System - Each system, which will be sold to the customer, consists of the probe, scanner, tower, monitor, and keyboard which are all medical grade components available for sale in multiple lanugages. The pricing of the IONIQ System may vary upon the volume of the IONIQ ProLung Test Kits that a customer buys. We refer to the IONIQ System internally as capital equipment or the razor handle in the ubiquitous razor/razor blade sales analogy.

	●	IONIQ ProLung Test Kit – IONIQ ProLung Test Kit sales should provide near term and continual cash flow. Each single-use, disposable, IONIQ ProLung Test Kit is sold in a nonsterile envelope that displays a unique identifier code that is required for access to a IONIQ ProLung Test Report, together with all the components necessary to assure precision test performance, patient comfort and hygiene. Each IONIQ ProLung Test Kit includes six diaphoretic electrodes, one probe tip and one moistening sponge. Initially, ProLung plans to sell the IONIQ ProLung Test Kit for approximately $400 each, available in boxes of 10 and 40. Each IONIQ ProLung Test Kit is encoded with a unique identifier number and bar code that releases a written test result to the ordering physician. We refer to the IONIQ ProLung Test internally as the disposable component or the razor blade in the ubiquitous razor/razor blade sales analogy.

IONIQ Sciences’ novel Electrical Impedance Analtyics (EIA) or bioimpedance technology simultaneously considers data from multiple measurement pathways and utilizes a patented predictive analytic algorithm to combine the individual measurements into a weighted average composite score that indicates an increased or decreased risk of malignancy in the individual in which the nodule has been detected. No images are generated by the IONIQ ProLung Test and extensive training is not required to interpret the composite score.

If required regulatory clearances are received, the IONIQ ProLung Test will be introduced to the market as a standard predictive analytic test without the need for transmission of a physical sample or specimen. Instead, the IONIQ ProLung Test acquires bioconductive measurement data by means of a patented probe and disposable diaphoretic electrodes placed on the back and hands. The data containing precision measurements is processed by a patented predictive analytic algorithm and a report is generated that may be used by the physician in addition to other risk factors, such as nodule size, family history, smoking history, and gender to evaluate patients with suspicious masses or lesions identified by CT scan. The IONIQ ProLung Test is non-invasive, rapid and non-radiating. It requires minimal patient preparation and can be completed in fewer than 30 minutes.

The IONIQ ProLung Test Procedure

	1.	IONIQ ProLung Test System is connected to the probe, to the electrode cables, and to the power supply. Following a brief power-on sequence, the IONIQ ProLung Test completes a self-diagnostic test.
	2.	The patient is seated.
	3.	IONIQ ProLung Test kit is opened and removed from its tamper-proof packaging.
	4.	Single-use diaphoretic electrodes are placed at sites on the patient’s back and arms.
	5.	Session data is entered including technician name, physician name, report delivery method and patient data.
	6.	Testing begins, as prompted by the device, by applying the probe to acquire measurement data from sites on the chest, shoulders and arms.
	7.	IONIQ System monitors the acquisition of real-time data. Should re-measurement be required, the device provides visual and audible notification that it has not received usable data.

Research and Clinical Trial Results

Our IONIQ ProLung Test has been evaluated in seven clinical trials at 24 clinical sites with 1,200 subjects generating more than 20,000,000 data points. We made modifications to the IONIQ ProLung Test throughout the research process and will continue to attempt to improve its performance. A description of each clinical trial is below:

Proof of Principle — McHenry, IL (2005)

●

Description. A blinded single-site study of 36 subjects was designed to detect differences in bioelectrical impedance measurements between biopsy-confirmed lung cancer subjects and age- and gender-matched control subjects. The trial was configured as a sequential design consisting of three individual cohorts. Following the completion of each cohort, the data was evaluated for the presence of a predictive model which would discriminate between the lung cancer patients and control subjects.

●

Results. The First Cohort of 12 subjects could not be utilized for statistical analysis because of an incorrectly calibrated device. An algorithm or predictive model was derived in the Second Cohort of 14 patients which fully discriminated between lung cancer patients and healthy volunteers.

●

Subsequent analysis of the Third Cohort offered potentially confounding results, but ProLung felt the hypothesis of feasibility of the device had been successfully demonstrated and that sufficient evidence of feasibility existed to proceed with further research.

Reliability and Repeatability — Salt Lake City, UT (2006)

●

Description. A single-site study to evaluate the variability of the IONIQ ProLung Test in 22 healthy volunteers.

●

Results. Measurement variables evaluated were the maximum and minimum conductance. The maximum and minimum conductance values obtained from one operator making repeated measurements with the same device on volunteer subjects over two days of testing were comparable, with slightly lower standard deviations for maximum conductance readings and extremely high reliability indices for both measures. For both data sets, the same measurement points were found to have minimal variability (and maximal reliability) indices. The Electro Pulmonary Nodule Scan showed a reliability index of 0.99 and a correlation between device replicates of 0.98.

Efficacy and Safety in the Target Indication a.k.a. FML-204 — Baltimore, MD (2012)

	●	Description. This single arm, single site algorithm finding and internal validation trial was designed to assess efficacy and safety in the risk stratification of the presence of or absence of malignancy in patients symptomatic of lung cancer who have a suspicious mass as confirmed by CT scan.

	●	Results. Final results included the identification of an algorithm capable of 90% sensitivity (correctly identifying 26 of 29 malignant masses), 92% specificity (correctly identifying 11 of 12 non-malignant masses), and Receiver Operating Characteristic (“ROC”) area (combined sensitivity and specificity) of 90% (correctly identifying 37 of 41 patients overall). Final results were presented in 2011 at the World Conference of the International Association for the Study of Lung Cancer and at the Annual Congress of the European Respiratory Society and were published in the April 2012 edition of the Journal of Thoracic Oncology.

		Though not part of the original study, a subsequent subset analysis was performed on Study subjects who had indeterminate results on FDG-PET scans (n=7). In this subset (3 benign, 4 malignant) the IONIQ ProLung Test correctly predicted the risk of malignancy in the index nodule being assessed. These results were presented at the International Association for the Study of Lung Cancer World Congress in Denver, CO, in September 2015 and published in volume 10, number 9, Supplement 2, Journal of Thoracic Oncology, p. S305).

Repeatability a.k.a. PL-209 — Salt Lake City, Utah (2015)

●

Description. The repeatability study enrolled sixty subjects, 30 male and 30 female, half of each gender with a body mass index (BMI) of 30 or more, and half with a BMI of 28 or less. Each subject was scanned twice on Day One and twice on Day Two. All scans were done by the same operator on the same IONIQ System. Fifty-nine subjects produced evaluable data. Four models (algorithms) were tested. The study was conducted by ProLung. Study objectives included quantifying the effects of gender, body mass index (BMI), day-to-day subject variability and variability of a single device when volume-averaged thoracic bioconductance was measured with the IONIQ ProLung Test.

●

Final Results. (1) Same-day variability is statistically significant (average second score is 0.0214 points lower), but the clinical impact of this finding is unclear (2) Day-to-day variability is impacted by the model (algorithm) chosen. One particular model with age (model 1b+age) has an ICC=0.958, indicating it is very repeatable. (3) Gender and BMI do not affect test performance. (4) Average test time is 18.5 minutes, with a range of 15-24 minutes. (5) The test is well tolerated and agreeable to test subjects. The repeatability study addressed several questions regarding use of the IONIQ ProLung Test. One significant limitation of this study is that no subjects with known pulmonary nodules or malignancy were enrolled. It is unknown whether pulmonary nodules or malignancy affect the repeatability of the IONIQ ProLung Test. While the study showed statistically significant variability of approximately 2% when testing the same subject twice on the same day, the clinical impact of this finding is unknown because it is not anticipated that patients will receive a second test on the same day in clinical use. While we note significant day-to-day variability when using an earlier model (the algorithm used in the Johns Hopkins Study, Journal of Thoracic Oncology, 2012), repeatability is markedly improved when using a more refined model.

PL-208 Study – (2012-2019)

●

Description. Three Validation studies have been completed for the IONIQ ProLung Test. The first is PL-208 which enrolled 420 patients across 15 US centers (ID: NCT01566682). This study was two-phased, with a 200-patient open-labelled training set to test and optimize an algorithm, followed by testing of the optimized algorithm on the diagnosis-blinded 174-patient validation set. Forty-six (46) subjects (11%) were excluded for being lost to follow up or having an inconclusive diagnosis, missing or inadequate device data. The predictive algorithm utilized the patient’s bioconductance measurements coupled with the patient’s age and a binary cut-off point of 0.5 was chosen to distinguish between high and low likelihood of cancer.

●

Final Results. The algorithm was locked and applied to a blinded validation set of 174 patients and yielded a Sensitivity of 69% Specificity of 49%, Positive Predictive Value (PPV) of 70%, Negative Predictive Value (NPV) of 47% and overall Accuracy of 61%.

PLW-208 Study – (2015-2016)

●

Description. The second validation trial (PLW-208) was completed by the Company’s licensor (ProLung Wuxi). This study enrolled 138 subjects at 2 centers in China.

●

Final Results. This study was similar in design to the US PL-208 Study and obtained a Sensitivity of 77%, Specificity of 60%, PPV of 82%, NPV of 41% and an Accuracy of 73%. In reviewing this study, the Sponsor determined that test method and operator training needed to be improved to obtain better results.

PLW-216 Study – (2017-2019)

	●	Description. Ultimately, the Study Sponsor (ProLung Wuxi) improved the device operator training, test method and device predictive algorithm. The Sponsor concluded the PLW-208 Study and initiated PLW-216, utilizing improved training, test method and a modified locked predictive algorithm. This PLW-216 Study was a single-phase validation study whereby the predictive algorithm was locked prior to the first patient being enrolled and the IONIQ ProLung Test results were provided to site investigators prior to knowing the subject’s actual diagnosis. The PLW-216 Study enrolled 486 subjects in China at 4 centers led by Dr. Bai, the Chair of the Chinese Alliance against lung Cancer and Director of the Shanghai Respiratory Research Institute (ID: NCT 02726633, registration No 20170226).

	●	Final Results. The Validation Study demonstrated improved performance yielding a Sensitivity of 84% Specificity of 73%, Positive Predictive Value (PPV) of 78%, Negative Predictive Value (NPV) of 80% and overall Accuracy of 79% from the US Study PL-208 (ID NCT0156668). This performance is comparable to other diagnostic cancer devices such as Mammogram (~sensitivity of 75%, specificity of 71%) and was demonstrated in a large sample size of 418 subjects included in the final analysis.

Other Research

PL-210 - ProLung Test Measurement Collection Protocols for Label Expansion (Ongoing NCT04134520)

Mexico. In 2011, ProLung supported a study with a hospital located in Mexico City. The study was administered by ProLung’s partner who was pursuing a joint venture license for the Mexico territory. The partner eventually abandoned the study. After receiving preliminary test results, ProLung had reason to question the quality of the data being gathered and withdrew its support of the study.

China. We issued a license to an entity conducting research in China in 2013. This Chinese researcher has independently changed the measurement collection methodology and classifier algorithm of the device. Their 486 patient Validation Study in China using the ProLung technology with the modified measurement collection methodology and modified classifier algorithm was completed in 2019. Preliminary results of the completed research in China have been presented at the 2017 American Thoracic Society International Conference Poster Session, as well as the 2019 International Symposium on Respiratory Diseases (ISRD) & American Thoracic Society (ATS) Joint Medical Conference.

In January 2019, ProLung amended the ProLung China license. The second addendum extends the exclusivity of our licensees’ license and allows ProLung to pursue a US FDA pre-submission review using the licensee’s Chinese clinical Protocol. The purpose of the US FDA pre-submission is to obtain the FDA’s feedback regarding the use of Chinese clinical data to demonstrate safety and efficacy for US FDA marketing clearance. ProLung may use the Chinese study data to support its US FDA application if it follows Good Clinical Practice, compliant with FDA regulations and is applicable to the US Population. The FDA recommends a pre-submission when seeking approval solely on foreign data. However, we believe it is likely FDA will require a smaller US Study replicating China results and showing repeatability. (Guidance for Industry and FDA Staff: FDA Acceptance of Foreign Clinical Studies Not Conducted Under IND Frequently Asked Studies, 21 CFR 314.106, 21 CFR 312.120).

In August 2019, ProLung announced that it amended the ProLung China license. The third addendum supports an expanded full collaboration business relationship wherein Prolung China Co. (“Prolung China”) and subsidiary (ProLung Biotech Wuxi) agree to provide all ProLung Biotech Wuxi Know-How and Improvements and clinical data which are used in Clinical Trials in China (PLW-208 and PLW-216) to ProLung, and other matters.

Italy and Switzerland. Four centers in Italy and one center in Switzerland conducted research with the IONIQ ProLung Test under the direction of local clinicians. At three of these sites, the research was part of a sales evaluation program for potential sale of the IONIQ ProLung Test. Subject enrollment at these sites did not conform to research protocols utilized by ProLung. Consequently, the data generated by these clinics were not published by the Company.

At two other sites, Geneva and Florence, additional physician-sponsored research was conducted. It is not known whether these sites conducted research with the IONIQ ProLung Test that was compliant with Good Clinical Practice or whether these patients conformed with the IONIQ ProLung Test patient selection criteria. However, in June 2017, at the World Congress of Thoracic Imaging the Geneva site posted results indicating Test sensitivity of 66% and a specificity of 66%. The positive predictive value was 94% and negative predictive value was 20%. Geneva researchers concluded the IONIQ ProLung Test could lower the need for invasive biopsies, especially in high risk patients. The small number of patients (n=27) precludes definitive conclusions.

Similarly, at a center in Florence, Italy, a study looked at 22 subjects undergoing the IONIQ ProLung Test and PET CT scans. They reported a sensitivity of 75% and a specificity of 50%, with a positive predictive value of 94% and a negative predictive value of 17%. Researchers concluded that the high positive predictive value of the IONIQ ProLung Test suggested utility in the evaluation of solitary pulmonary nodules, adding that further research was warranted. This was presented in the form of a poster at the 2017 American Thoracic Society Conference.

Governmental Regulations

Our business is subject to extensive federal, state, local and foreign laws and regulations, including those relating to the protection of the environment, health and safety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of subjective interpretations. In addition, these laws and their interpretations are subject to change, or new laws may be enacted.

Both federal and state governmental agencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that we have structured our business operations and relationships with our customers to comply with all applicable legal requirements. However, it is possible that governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations most relevant to our business.

US Food and Drug Administration regulation of medical devices.

The Federal Food, Drug and Cosmetic Act (the “FDCA”) and FDA regulations establish a comprehensive system for the regulation of medical devices intended for human use. Our products include medical devices that are subject to these, as well as other federal, state, local and foreign, laws and regulations. The FDA is responsible for enforcing most of the federal laws and regulations governing medical devices in the United States.

The FDA classifies medical devices into one of three classes - Class I, Class II, or Class III depending on their level of risk and the types of controls that are necessary to ensure device safety and effectiveness. The class assignment is a factor in determining the type of premarket submission or application, if any, that will be required before marketing in the United States. We currently anticipate that the IONIQ System will be classified as a Class II de novo medical device.

	●	Class I devices present a low risk and are not life-sustaining or life-supporting. The majority of Class I devices are subject only to “general controls” -e.g., prohibition against adulteration and misbranding, registration and listing, good manufacturing practices, labeling, and adverse event reporting. General controls are baseline requirements that apply to all three classes of medical devices.

	●	Class II devices present a moderate risk and are devices for which general controls alone are not sufficient to provide a reasonable assurance of safety and effectiveness. Devices in Class II are subject to both general controls and “special controls” -e.g., special labeling, compliance with industry standards, and post market surveillance. Unless exempted, Class II devices typically require FDA clearance before marketing, through the premarket notification (“510(k)”) process.

	●	The de novo application process provides a pathway to Class I or II classification for medical devices for which general controls or general and special controls provide a reasonable assurance of safety and effectiveness, but for which there is no legally marketed predicate device.

	●	Class III devices present the highest risk. These devices generally are life-sustaining, life-supporting, for a use that is of substantial importance in preventing impairment of human health, present a potential unreasonable risk of illness or injury, or are not substantially equivalent to a legally marketed predicate device. Class III devices are devices for which general controls, by themselves, are insufficient and for which there is insufficient information to establish special controls to provide a reasonable assurance of safety and effectiveness. Class III devices are subject to general controls and typically require FDA clearance of a premarket approval (“PMA”) application before marketing.

Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially marketed, distributed or sold in the United States. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA.

510(k) pathway

The 510(k)-review process compares a new device to a legally marketed device. Through the 510(k) process, the FDA determines whether a new medical device is “substantially equivalent” to a legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed device has the same intended use as the predicate device, and either the same or similar technological characteristics as the predicate device, or if there are differences in technological characteristics, the differences do not raise different questions of safety and effectiveness as compared to the predicate, and the information submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device.

To obtain 510(k) clearance, a company must submit a 510(k)-application containing sufficient information and data to demonstrate that its proposed device is substantially equivalent to a legally marketed predicate device. These data generally include non-clinical performance testing (e.g., software validation, animal testing, electrical safety testing), but clinical data may also be required. Typically, it takes six to twelve months for the FDA to complete its review of a 510(k) submission; however, it can take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, which may significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to be either (1) substantially equivalent and states that the device can be marketed in the United States, or (2) not substantially equivalent and states that device cannot be marketed in the United States. Depending upon the reason(s) for the not substantially equivalent finding, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization.

After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a major change in its intended use, including significant modifications to any products or procedures, requires a new submission and clearance of a new 510(k). The FDA relies on each manufacturer to make and document its determination that a new 510(k) is (or is not) required, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If we are granted an initial 510(k), we may make minor product enhancements that we believe do not require new 510(k) clearance. If the FDA disagrees with our determination regarding whether a new 510(k) clearance was required for these modifications, we may need to cease marketing and/or recall the modified device. The FDA may also subject us to other enforcement actions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.

De novo pathway

If, at the end of the FDA review of a 510(k), the FDA determines that a device is “Not Substantially Equivalent” (“NSE”) due to the unavailability of a predicate device, a new intended use or different technological characteristics that raise different questions of safety and effectiveness, the FDA may indicate that the device may be suitable for review under the de novo classification process. If the FDA believes general controls or general and special controls may provide reasonable assurance of safety and effectiveness, the FDA may indicate in the NSE letter that the product may be appropriate for the de novo classification process under section 513(f)(2) of the Federal Food Drug and Cosmetic Act (“FD&C Act”). Inclusion of this language within an NSE letter does not indicate that sufficient information currently exists to support a successful de novo request, but simply indicates that given the risk profile of the device, it seems reasonable that de novo classification may be appropriate.

Alternatively, if a manufacturer believes their device is appropriate for classification into Class I or Class II and has determined, based on currently available information, there is no legally-marketed predicate device, they may submit a de novo request without a preceding 510(k) and NSE.

Once a de novo request is received (regardless of whether it is preceded by a 510(k) and NSE determination), the FDA will also check that the content of the de novo request includes the information required by section 513(f)(2) of the FD&C Act. De novo requests that lack information to determine whether a potential predicate device exists may be placed on hold. If the de novo request is missing information and/or data necessary to determine whether general controls or general and special controls can provide reasonable assurance of safety and effectiveness, the FDA may issue an additional information (AI) letter or request information via interactive review. If the de novo requestor fails to provide a complete response within 180 calendar days of the date of the AI request, the FDA will consider the de novo request to be withdrawn. If a de novo request is withdrawn due to failure to submit adequate information, a new de novo request is required in order to reinitiate review of the device under the de novo classification process.

If the data and information submitted demonstrate that general controls or general and special controls are adequate to provide reasonable assurance of safety and effectiveness, the FDA will grant the de novo request. If a de novo request is granted, the FDA will issue you a written order granting the de novo request and identifying the classification of the device (either class I or class II). For class II devices, the FDA will also identify the applicable special controls. Effective on the date of the granting order, the requester may immediately begin marketing the device subject to the general controls and any identified special controls. The device may be used as a predicate device for future 510(k) submissions as appropriate.

Premarket approval pathway

Unlike the comparative standard of the 510(k) pathway, the PMA approval process requires an independent demonstration of the safety and effectiveness of a device. PMA is the most stringent type of device marketing application required by the FDA. PMA approval is based on a determination by the FDA that the PMA contains sufficient valid scientific evidence to ensure that the device is safe and effective for its intended use(s). A PMA application generally includes extensive information about the device including the results of clinical testing conducted on the device and a detailed description of the manufacturing process.

After a PMA application is accepted for review, the FDA begins an in-depth review of the submitted information. FDA regulations provide 180 days to review the PMA and make a determination; however, the review time is normally longer (e.g., 1-3 years). During this review period, the FDA may request additional information or clarification of information already provided. Also, during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that the device is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the applicant’s establishment to ensure compliance with the Quality System Regulation (“QSR”), which governs the methods used in, and the facilities and controls used for, the design, manufacture, packaging, labeling, storage, installation, and servicing of finished devices.

Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information is needed), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A company may not market a device subject to PMA review until the FDA issues an order approving the PMA. As part of a PMA approval (or 510(k) clearance), the FDA may impose post-approval conditions intended to ensure the continued safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinical data. Failure to comply with the conditions of approval (or clearance) can result in materially adverse enforcement action, including withdrawal of the approval (or clearance).

Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before being implemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’s time for review of a PMA supplement vary depending on the nature of the modification.

Clinical trials

FDA generally prohibits the shipping and marketing of medical devices in the absence of a premarket clearance or approval (where required). However, the FDA’s Investigational Device Exemption (“IDE”) regulation exempts the provision of devices for use in certain types of clinical trials – i.e., clinical trials to collect safety and effectiveness data for investigational devices, and clinical trials evaluating new intended uses and/or certain modifications to a legally marketed device – from this prohibition. This regulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial, submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control the disposition of the investigational device, submit required reports, etc.

Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing, mitigating or treating disease, or otherwise preventing impairment of human health, or that otherwise present a serious risk to the health, safety, and welfare of a subject) require FDA and Institutional Review Board (“IRB”) approval prior to starting the trial. FDA approval is requested through submission of an IDE application. Clinical trials of non-significant risk (“NSR”), devices (i.e. devices that do not meet the regulatory definition of a significant risk device) do not require FDA approval but do require IRB approval before starting. The clinical trial sponsor is responsible for making the initial determination of whether a clinical study is significant risk or NSR; however, a reviewing IRB and/or FDA may review this decision and disagree with the determination.

An IDE application must be supported by appropriate data, such as nonclinical performance data, animal and laboratory testing results, showing that it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of an IDE will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place a clinical trial on hold or terminate it if, among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.

As noted above, the FDA may require a company to collect clinical data on a device in the post market setting.

The collection of such data may be required as a condition of PMA approval. The FDA also has the authority to order, via a letter, a post market surveillance study for certain devices at any time after they have been cleared or approved.

Pervasive and continuing FDA regulation

After a device is placed on the market, regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply. These include, but are not limited to:

	●	Establishment registration and device listing requirements;

	●	QSR, which governs the methods used in, and the facilities and controls used for, the design, manufacture, packaging, labeling, storage, installation, and servicing of finished devices;

	●	Labeling requirements, which mandate the inclusion of certain content in device labels and labeling, and when fully implemented, will generally require the label and package of medical devices to include a unique device identifier (“UDI”), and which also prohibit the promotion of products for uncleared or unapproved, i.e., “off-label,” uses;

	●	Medical Device Reporting (“MDR”), regulation, which requires that manufacturers and importers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur; and

	●	Reports of Corrections and Removals regulation, which requires that manufacturers and importers report to the FDA recalls (i.e., corrections or removals) if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health; manufacturers and importers must keep records of recalls that they determine to be not reportable.

The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include, but is not limited to, the following sanctions:

	●	Notice of inspectional observations;

	●	Untitled letters or warning letters;

	●	Fines, injunctions and civil penalties;

	●	Recall or seizure of our products;

	●	Operating restrictions, partial suspension or total shutdown of production;

	●	Refusing our request for 510(k) clearance or premarket approval of new products;

	●	Withdrawing 510(k) clearance or premarket approvals that are already granted; and

	●	Criminal prosecution.

We are subject to unannounced device inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance with applicable state public health regulations. These inspections may include our suppliers’ facilities.

Marketing Approvals Outside the United States

Sales of medical devices outside the United States are subject to foreign government regulations, which vary substantially from country to country. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ.

Europe

Under the European Union Medical Device Directive, or EU MDD, medical devices must meet the EU MDD requirements and receive a CE marking certification prior to marketing in the European Union, or EU, which we received for the IONIQ ProLung Test in May 2013. CE marking is the uniform labeling system of products designed to facilitate the supervision and control of the EU concerning manufacturers’ compliance with the various regulations and directives of the EU and to clarify the obligations imposed in the various legislative provisions in the EU. Use of a uniform product labeling indicates compliance with all the directives and regulations required for the application of such labeling, and it is effective as a manufacturer’s declaration that the product meets the required criteria and technical specifications of the relevant authorities such as health, safety, and environmental protection. CE marking ensures free trade between the EU and European Free Trade Association countries (Switzerland, Iceland, Liechtenstein, and Norway) and permits the enforcement and customs authorities in European countries not to allow the marketing of similar products that do not bear the CE marking sign. Such certification allows, among other things, marking the products (according to various categories) with the CE marking and their sale and marketing in the EU.

CE marking certification requires a comprehensive quality system program, comprehensive technical documentation and data on the product, which are then reviewed by a Notified Body, or NB. An NB is an organization designated by the national governments of the EU member states to make independent judgments about whether a product complies with the EU MDD requirements and to grant the CE marking if we, and our product, comply with specified terms. After receiving the CE marking, we must pass a review carried out by the competent NB annually, under which it audits our facilities to verify our compliance with the ISO 13485 quality system standard.

Compliance with the ISO 13485 standard, for medical device quality management systems, is required for regulatory purposes. ISO standards are recognized international quality standards that are designed to ensure that we develop and manufacture quality medical devices. Other countries are also instituting regulations regarding medical devices. Compliance with these regulations requires extensive documentation and clinical reports for all our product candidates, revisions to labeling, and other requirements such as facility inspections to comply with the registration requirements.

China

China’s medical device market, currently in a rapid state of expansion, is overseen by the China Food and Drug Administration, or CFDA (formerly the State Food and Drug Administration). The CFDA issues registration certificates required for all medical devices sold in China. The CFDA uses a risk-based system, and its approval process requires mandatory testing for Class II and III devices. Class II devices are moderate-risk devices and Class III devices are high-risk medical devices. Third-party review of devices is currently not allowed in China; only the CFDA is authorized to approve devices. The registration process requires the submission of a registration standard along with device samples for testing. Manufacturers of Class II and Class III medical devices are also required to demonstrate that the device has been approved by the country of origin with documents like a CE certificate, 510(k) letter and PMA approval and compliance with ISO 13485, and they may also be required to submit clinical data in support of their application. In addition to these requirements, all medical device manufacturers must also include product information in Chinese on all packaging and labeling. Manufacturers exporting medical devices to China must appoint several China-based agents to act on their behalf. These include a registration agent to coordinate the CFDA registration process, a legal agent to handle any adverse events reported with a registered device, including a product recall, and an after-sales agent to provide technical service and maintenance support.

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 CMS, other divisions of the United States Department of Health and Human Services (e.g., the Office of Inspector General), the United States Department of Justice and individual United States Attorney offices within the Department of Justice, and state and local governments. These regulations include:

●

the federal healthcare program anti-kickback law which prohibits, among other things, persons from knowingly and willfully soliciting, receiving or providing any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, in return for referring an individual for the furnishing or arranging for the furnishing of any item or service for which payment may be made in whole or in part under a Federal health care program, or in return for the purchasing, leasing, ordering, or arranging for or recommending purchasing, leasing, or ordering any good, facility, service or item, for which payment may be made in whole or in part under federal healthcare programs such as the Medicare and Medicaid programs;

	●	federal false claims 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 government reimbursement programs that are false or fraudulent. The government may assert that a claim including items or services resulting from a violation of the federal healthcare program anti-kickback law or related to off-label promotion constitutes a false or fraudulent claim for purposes of the federal false claims laws;

	●	the federal Health Insurance Portability and Accountability Act of 1996 fraud and abuse provisions, which prohibit executing a scheme to defraud any healthcare benefit program, willfully obstructing a criminal investigation of a health care offense, or making false statements or concealing a material fact relating to payment for healthcare benefits, items, or services;

	●	the Federal Physician Payments Sunshine Act within the Patient Protection and Affordable Care Act, and its implementing regulations, require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals, and to report annually certain ownership and investment interests held by physicians and their immediate family members; 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 payer, including commercial insurers, many of which differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts.

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. The Health Insurance Portability and Accountability Act, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of protected health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates”—independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, state laws govern 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.

Post-Marketing Regulations

Following approval of a new product, a company and the approved product are subject to continuing regulation by the FDA and other federal and state regulatory authorities, including, among other things, monitoring and recordkeeping activities, reporting to applicable regulatory authorities of adverse experiences with the product, providing the regulatory authorities with updated safety and efficacy information, product sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting for uses or in patient populations not described in the product’s approved labeling (known as “off-label use”), limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses, manufacturers may not market or promote such off label uses. Modifications or enhancements to the products or labeling or changes of site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.

Other Regulatory Matters

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the United States, CMS, other divisions of the Department of Health and Human Services, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments. Sales, marketing and scientific/educational programs must also comply with federal and state fraud and abuse laws. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. Manufacturing, sales, promotion and other activities are also potentially subject to federal and state consumer protection and unfair competition laws.

The distribution of medical device products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of medical device products.

Our Marketing Process

We must receive separate regulatory approvals from the FDA and equivalent regulatory bodies in other countries for each of the devices before we can sell them commercially in the US or internationally. We cannot make the claims necessary to market any of our product candidates until we have completed the requirements for regulatory authorization. We do not know whether regulatory authorities will grant authorization for any of the products that we, our marketing partners, or distribution partners will develop.

A summary of the status of our marketing authorizations in the key initial markets we have identified is set forth below:

	●	United States. We submitted our de novo application to the U.S. FDA in February 2022. As background, we applied for marketing clearance under Section 510(k) from the FDA in September of 2013. After review of the 510(k) application, the FDA issued a letter to ProLung in May 2014 indicating that the FDA believed that our 510(k) would likely be found Not Substantially Equivalent to a legally marketed predicate device and the FDA believed ProLung may be suitable for de novo classification. Subsequently, we submitted a de novo petition in August of 2014. In February 2015, we received a Substantive Review of the de novo petition from the FDA requesting clarification of research to date, labeling, updated and additional safety testing, clarification of the Indications For Use (IFU) statement, software and results of the ongoing multisite trial (PL-208). We communicated with the FDA by conference call, in writing, and in a July 16, 2015, face-to-face Submission Issue Meeting. We prepared and provided a written response to the FDA, but it was never formally reviewed by the FDA because it did not include the PL-208 results and the FDA does not consider responses in a piecemeal fashion. Statutory requirements for an active FDA application mandated ProLung’s withdrawal of the de novo petition while awaiting results of PL-208. In August 2015, the FDA considered the de novo petition withdrawn due to inadequate response because the written response did not include the PL-208 results, and as a result we will need to file an entirely new application. The issues that the FDA identified in the letter are as follows:

	●	Clinical and Statistical Concerns. The FDA requested clarification on research to date and additional clinical evidence including a validation study.

	●	Risk Analysis Concerns. The FDA asked us to address the risks associated with false positive and false negative test results.

	●	Device Description and Technology. The FDA asked for clarification regarding the principle of operation of the device and expressed concerns regarding the accuracy of using direct current for device measurements.

	●	Electrical Safety and Electromagnetic Compatibility Concerns. The FDA asked for additional information and specific testing mitigation for electrical shock in the event of an electrical failure.

	●	Software Concerns. The FDA asked for additional information including a complete software description, an additional device hazard analysis and a description of unresolved anomalies.

	●	Indications for Use Concerns. The FDA requested that the Indications For Use statement better define terms used such as “risk stratification” and “indeterminate significance” and include the clinical utility of the device.

	●	Additional Labeling Concerns. The FDA requested that labeling include all the measurement point locations, the clinically determined accuracy of the device and the risks of false positive and false negative results.

Since receiving the substantive de novo review, we have completed the US PL-208 and Chinese PLW-216 validation studies and have collaborated with the FDA in multiple pre-submission meetings. The pre-submission meetings have primarily focused on the utilizing data and results from the PLW-216 Study to support a de novo submission, which we subsequently submitted to the FDA in February 2022.

In February 2020, the FDA designated the IONIQ ProLung Test a Breakthrough Device. Through the Breakthrough Device program, the FDA will provide ProLung with expedited reviews and the Centers for Medicare Medicaid Services (CMS) has provisions for a simpler and faster pathway to reimbursement. This is not a marketing clearance.

In 2020, we also received feedback from the FDA regarding the PLW-216 Study. The FDA has shared concerns regarding, indications for use, risks of the device, mechanism of action, device usability and repeatability, efficacy, PLW-216 Study design and applicability of the PLW-216 study results to the US population.

	●	European Union. CE marking was granted as of May 10, 2013 for the IONIQ ProLung Test which permits the product to be sold throughout the European Economic Area (European Union member states plus Iceland, Liechtenstein and Norway), Switzerland, and Turkey. CE marking requires manufacturers to maintain an ISO 13485 Quality System.

	●	China. The CFDA (previously known as the SFDA) roughly follows the FDA model and is the source of clearance for the marketing and sale of medical devices in China. To be sold in China, medical devices must be registered with Chinese health authorities. In February 2014, the Company’s licensor in China received clearance to manufacture the device from the Beijing government. Additional clearances are required to market and sell the device in this market.

After each respective regulatory clearance is obtained, the next step in each of these markets is for insurance companies or government agencies, as applicable, to agree to reimburse providers for the IONIQ ProLung Test. We have not commenced this process in the US or any other market, as we do not yet have marketing authorizations.

Manufacturing Requirements

As a manufacturer of medical devices, we must comply with the 21 CFR Part 820 Good Manufacturing Practice regulations established by the FDA. These requirements are meant to ensure that medical devices are safe and effective. We maintain a quality management system that includes standard operating procedures for key processes such as design, manufacturing, packaging, labeling, storage, installation, servicing, record keeping, complaint handling and corrective and preventative action. Our quality management system is currently ISO 13485 certified and is intended to meet the 21 CFR Part 820 Good Manufacturing Practice regulations. We will also be subject to similar requirements imposed by other countries.

Manufacturing

We currently manufacture the IONIQ ProLung Test and the IONIQ ProLung Test Kit. When volume requirements exceed current manufacturing capacity, we intend to utilize contract manufacturers for the physical manufacturing of our products. This may afford us numerous benefits, including:

	●	the ability to ramp up production quickly;

	●	access to leading technologies, supply chain networks and best-in-class manufacturing processes for its products;

	●	flexibility to use one or many manufacturers in many regions of the world to optimize costs, production volumes, material availability, lead times, and to meet various regional regulations.

We have interviewed, performed site visits, and qualified multiple, redundant contract manufacturers which may be required to produce our products. We have no contractual obligations with such contract manufacturers for the manufacturing of our products.

Our prospective contract manufacturers will source our product components from multiple specialized vendors that supply plastics, sheet metal, machining, cables, wire harnesses, and other computer hardware components. We maintain our own design control and ISO 13485 quality system.

Research and Development

The Company spent $761,052 and $738,734 on company-sponsored research and development during fiscal years ending December 31, 2021, and 2020, respectively.

Employees

As of December 31, 2021, we had eight employees. As of April 12, 2022, we had eight employees.

Emerging Growth Company

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), and we may take advantage of certain exemptions from various reporting requirements that are applicable to other 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 may 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. We are choosing to take advantage of the extended transition period for complying with new or revised accounting standards. As a result, our financial statements may not be comparable to those of companies that comply with public company effective dates.

As of December 31, 2021, we remain an “emerging growth Company. We believe we will remain an “emerging growth company” through at least December 31, 2022.

Item 1A. Risk Factors

Our business, operations, and financial condition are subject to certain risks and uncertainties. Should one or more of these risks or uncertainties materialize, or should any underlying assumptions prove incorrect, our actual results will vary, and may vary materially, from those anticipated, estimated, projected, or expected. Among the key factors that may have a direct bearing on our business, operations or financial conditions are the factors identified below:

RISKS RELATED TO OUR STAGE OF DEVELOPMENT

We are a development stage company with limited revenue and no assurance of earning significant revenue over the long term.

We were organized in 2004 and since that date have experienced significant losses from operations. We are in the process of commercializing our proprietary IONIQ ProLung Test in the US and Europe and seeking marketing clearance for the IONIQ ProLung Test in the United States and expect to incur additional operating losses in the near term. We have generated limited revenue from the sale of our products and services. The amount of losses we will incur, and whether we will become profitable at all, are highly uncertain. Our net loss for the year ended December 31, 2021 was $3,615,029 and for the year ended December 31, 2020 was $2,727,616.

Our future success depends on our ability to begin generating revenues on a regular and continuing basis and to properly manage costs. Our ability to generate revenues depends on several factors, some of which are outside our control. These factors include our ability to obtain necessary government and regulatory marketing authorizations, our ability to successfully commercialize the IONIQ ProLung Test, our ability to protect intellectual property related to the IONIQ ProLung Test, our ability to obtain coverage and reimbursement for the test procedure from Medicare and other third- party payers, and our ability to effectively market our products. If we cannot expand our revenue significantly over the long term, we will not be profitable.

We are dependent upon financings to fund our operations and may be unable to continue as a going concern.

We do not generate sufficient cash flows from operations to meet the cash requirements of our operations and other commitments without raising funds through the sale of debt and/or equity securities. We do not expect to generate enough cash, if any, from operations to meet our requirements in the near term. Proceeds raised from funding activities are required for us to have funds to meet our obligations for the foreseeable future. Our ability to continue as a going concern will depend, in large part, on our ability to obtain additional financing and generate positive cash flow from operations, neither of which is certain. If we are unable to achieve these goals, our business would be jeopardized and it may not be able to continue operations.

We will need significant capital to execute our business plan.

We currently generate no revenue, and we require at least $2.0 million in capital each year to operate our business. We also anticipate requiring additional capital to conduct additional clinical studies prior to submitting an application for FDA clearance for our IONIQ ProLung Test, If we obtain FDA clearance, of which there is no assurance, we will need to obtain significant additional capital in order to execute our sales and marketing go-to-market plan.

We do not currently have any arrangements or credit facilities in place as a source of funds, and there can be no assurance that we will be able to raise sufficient additional capital on acceptable terms, or at all. We may seek additional capital through a combination of private and public equity offerings, debt financings and strategic collaborations. Debt financing, if obtained, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, could increase our expenses and require that our assets secure such debt. Moreover, any debt we incur must be repaid regardless of our operating results. Equity financing, if obtained, could result in dilution to our then existing stockholders. If such financing is not available on satisfactory terms, or at all, we may be required to delay, scale back or eliminate our testing and developing activities or, if we obtain FDA clearance, marketing efforts, which will harm our operations and financial condition, if we are unable to secure sufficient capital to fund our operations, we may have to discontinue operations and liquidate (and we anticipate that our liquidation value would be nominal).

We have issued significant indebtedness, and, if we are unable to repay or refinance it, our creditors could force us into bankruptcy.

As of December 31, 2021, we had outstanding Notes and Loans totaling $10,645,429. Nearly the entire balance of our loan obligations are scheduled to come due in September 2023 as a result of an amendment with our Convertible Note holders undertaken in March 2022. If we default under our loan obligations, and we do not have sufficient cash resources to repay the loan, our creditors would have the ability to force us into bankruptcy. As a result of any bankruptcy proceeding, if cash resources were depleted, it is doubtful that there will be any amount available for distribution to our stockholders.

Risks Related to Our Business and Industry

We are in the early stages of commercialization and our IONIQ ProLung Test may never achieve commercial market acceptance.

Our IONIQ ProLung Test is approved and commercially available only in a limited number of countries and will not be available for sale in other countries, including the United States, until clinical development is completed and regulatory authorizations are obtained. Following our de novo application for marketing clearance for the IONIQ ProLung Test from the FDA, in February 2015, we received a letter from the FDA identifying many issues, questions, and concerns in our submission, including issues regarding our proposed risk classification for the test, the study design and analysis plan for the clinical trial intended to support our submission, along with certain other questions. In subsequent communications and meetings with the FDA, we succeeded in addressing a number of the FDA’s concerns, and we were asked to complete a clinical study. In 2018, before breaking the study data blind and analyzing the amassed clinical data for our PL-208 study, we collaborated with the FDA through two formal Pre-Submission Meetings regarding our PL-208 Study Statistical Analysis Plan, study design, device output and statistical approaches. Furthermore, in 2020 we have received feedback from the FDA regarding the PLW-216 Study. The FDA has shared concerns regarding, indications for use, risks of the device, mechanism of action, device usability and repeatability, efficacy, PLW-216 Study design and applicability of the PLW-216 study results to the US population. We have ongoing meetings with the FDA to address these significant comments from the FDA many of which have not yet been resolved.

The FDA will likely require additional clinical study work and resolve or negotiate the removal of the remaining issues previouslyidentified by the FDA, as well as address issues to be identified in the future, before clearing the IONIQ ProLung Test for marketing. This maynever occur. Moreover, the successful commercialization of our product will require significant, time-consuming and costly sales and marketing efforts. If the commercialization of our IONIQ ProLung Test is unsuccessful or we are unable to market our IONIQ ProLung Test due to market developments, failure to obtain and maintain the regulatory authorizations necessary for our business to be commercially viable, development of alternative diagnostics or otherwise, we will be required to expend significant additional resources on research and development to improve our IONIQ ProLung Test. The development of a new test will be subject to the risks of failure inherent in the creation of any innovative new medical technology. These risks include the possibilities that our test will not be effective or of acceptable quality, will fail to receive necessary regulatory authorizations, will be uneconomical to manufacture or market or does not achieve broad market acceptance, and that third parties market a superior or equivalent product. Even if our test is effective, it may not be accepted by patients or physicians. The failure of our research and development activities to result in any commercially viable products would have a material adverse effect on our business and financial condition.

We are reliant on a single product and if we are not successful in commercializing the IONIQ ProLung Test and are unable to develop additional products, our business will not succeed.

We have no experience commercializing the IONIQ System and IONIQ ProLung Test. We currently have no products available for sale. If the IONIQ ProLung Test or our other products in development are not successful at a level sufficient to generate a profit and we are unable to develop additional products, our business will not succeed.

The ability to add to the product suite is subject to the availability of additional funds and certain factors not in our control, such as government policy.

We are subject to litigation risk if our IONIQ ProLung Test is not effective.

The nature of the IONIQ ProLung Test as a medical technology platform and the general litigious environment of the market should be regarded as potential risks that could significantly and adversely affect our financial condition and results of operations in the future. If the IONIQ ProLung Test does not perform as demonstrated in well controlled clinical trials and as reviewed by the FDA, there could be significant, even life-threatening, adverse consequences. We may be subject to claims against us as a result of the failure of the IONIQ ProLung Test or other devices. We may also be subject to claims even though the injury is due to the actions of others, such as manufacturers or medical personnel. If we are sued, we may not have the resources to defend any such lawsuit or pay any related judgments. In addition, even the existence of a lawsuit will divert management’s attention from the development and commercialization of the IONIQ ProLung Test. Any insurance obtained by us may not adequately cover the amount or nature of any claim asserted against us and we are exposed to the risk that claims may be excluded from insurance coverage and that insurers may become insolvent. Moreover, there may not be any insurance available that would adequately cover all such risks.

We are subject to litigation risk as a result of our prior offering activities.

We recently experienced a very public proxy battle for control of the board of directors. In that process, both sides of the proxy battle made numerous allegations of wrongdoing by former officers and directors of ProLung. The allegations have led to expressions of frustration and anger by existing shareholders, certain of which have threatened to file lawsuits against ProLung, its former executives and various current and former directors. Complaints by shareholders and former employees have also led to an investigation being opened by the Utah Division of Securities related to the Company’s and individuals’ activities.

On April 23, 2019, the Utah Division of Securities (the “Division”) filed a Notice of Agency Action and an Order to Show Cause before the Division of Securities of the Department of Commerce of the State of Utah against the Company, Jared Bauer and former Board Members (Clark Campbell, Tim Treu, Todd Morgan and Robert Raybould).

In January 2020, the Division issued a Stipulation and Consent Order which set forth the following: 1) the Company agrees to settle the matter with the Division by way of the Stipulation and Consent Order; 2) the Stipulation and Consent Order fully resolves all claims the Division has against the Company pertaining to the Order to Show Cause; 3) the Division, ProLung and Bauer, agree to promptly file a stipulation and joint motion to dismiss ProLung and Bauer from this administrative action, with respect to Count 1 against ProLung and Bauer (the only claim brought against Bauer); 4) In or about April 2014, the Company Board of Directors circulated a consent agreement regarding the issuance of 582,102 (72,763 post-split) ProLung stock certificates to select members of the ProLung Board of Directors in connection with “financing services provided” by those members; 5) In or about April 2014, ProLung issued stock grants of 216,000 (27,000 post-split) shares to Robert W. Raybould, 16,350 (2,044 post-split) shares to Steve Eror, 63,750 (7,968 post-split) shares to Treu; 193,500 (24,118 post-split) shares to Campbell; and 97,500 (12,188 post-split) shares to Morgan; 6) Subsequent to issuance of those shares, ProLung was informed by counsel of potential consequences for Pro Lung employing unlicensed agents and individuals receiving the shares as compensation directly for sale of securities without a securities license, as opposed to receiving shares as compensation for generalized board service. Subsequently, no further shares were issued as compensation for fundraising. Mr. Eror returned his shares to the Company. However, Raybould, Treu, Campbell and Morgan did not return their shares to the Company. ProLung did not disclose the potential licensing violation until on or about December 3, 2018, in its Note Purchase Agreements.

As set forth by the Company in its Form 8-K dated November 27, 2019, Campbell, Treu, Morgan, and Raybould entered into Stipulation and Consent Orders wherein they returned shares of stock to the Company’s treasury and paid fines to the Division of Securities.

On January 9, 2020, the Division entered an order as follows: 1) entering certain Findings and Conclusions by the Division, which ProLung admitted via a Stipulation and Consent Order; 2) ordering ProLung to cease and desist from violating Utah Uniform Securities Act (the “Act”) and to comply with the requirements of the Act in all future business in the state of Utah; 3) ordering ProLung to disclose the contents of the order to investors and prospective investors in all future capital raising efforts and disclosure documents of ProLung; and 4) Ordering ProLung to pay a fine of $55,000 to the Division.

We may incur substantial product liability expenses due to manufacturing or design defects, or the use or misuse of our products.

Our business exposes us to potential liability risks that are inherent in the testing, manufacturing and marketing of medical products. We may face liability to our distributors and customers if our products are not manufactured as per specifications or if such specifications cause the products to become unsafe or fail to function as marketed or sold. We may also face substantial liability for damages if our products produce adverse side effects or defects are identified with any of our products that harm patients and other users. Any such failures or defects may lead to a breakdown in our relationships with distributors and purchasers leading to a substantial decline in or collapse of our market. In addition, if any judgments or liabilities are material in size, we may be unable to satisfy such liabilities. Any product liability could harm our operations and a large judgment could force us to discontinue our operations.

We are subject to the risk of product recalls if our products are defective.

The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture that could affect patient safety. In the case of the FDA, the authority to require a recall must be based on an FDA finding where there is a reasonable probability that the device would cause serious adverse health consequences or death. A government- mandated recall or voluntary recall by us or one of our distributors could occur as a result of component failures, manufacturing errors, design or labeling defects, or other issues. Recalls, which include corrections as well as removals, of any of our products would divert managerial and financial resources and could have an adverse effect on our financial condition, harm our reputation with customers, and reduce our ability to achieve expected revenues.

Lack of adequate third-party coverage and reimbursement for our customers could delay or limit the adoption of our products.

We may experience limited or no sales growth resulting from limitations on coverage and reimbursement for the diagnostic procedures performed with our products by third-party payors, and we cannot assure you that our sales will not be impeded and our business harmed if third-party payors fail to provide reimbursement for such procedures that customers view as adequate. We are pursuing CPT and HCPCS codes since no existing codes appear to cover the purchase and use of our device.

Moreover, many private payors look to Medicare in setting their reimbursement policies and amounts. If Medicare does not offer adequate reimbursement for the services offered using our products, this may affect reimbursement determinations by certain private payors.

The absence of, or limits on, reimbursements may affect our revenues and our ability to achieve profitability.

The cost of a significant portion of healthcare is funded by governmental, and other third-party, insurance programs. It is possible that our products will not be covered or adequately reimbursed by governments or insurance providers, which will seriously harm our ability to generate revenue. In addition, even if payers cover our products (or the services in which our products are used), limits on reimbursement imposed by such programs may adversely affect the ability of hospitals and others to purchase our products. In addition, limitations on reimbursement for procedures which utilize our products could adversely affect our business.

If the IONIQ ProLung Test is not accepted by physicians and patients, we will be unable to achieve market acceptance.

Patients may be unwilling to depart from the current standard of care and opt not to undergo the IONIQ ProLung Test. In addition, physicians tend to be slow to change their medical treatment practices because of perceived liability risks arising from the use of new products. Physicians may not recommend or order the IONIQ ProLung Test until there is long-term clinical evidence to convince them to alter their existing patient management methods, there are recommendations from prominent physicians that the IONIQ ProLung Test is safe, effective, and clinically useful, and that reimbursement or insurance coverage is available. We cannot predict when, if ever, physicians and patients may adopt the use of the IONIQ ProLung Test. If the IONIQ ProLung Test does not achieve an adequate level of acceptance by patients, physicians and healthcare payors, we may not generate significant product revenue and we may not become profitable.

Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by early commercial stage companies. Potential investors should carefully consider the risks and uncertainties that a company with a limited operating history will face. In particular, potential investors should consider that we cannot assure you that we will be able to:

	●	successfully execute our current business plan for the commercialization of the IONIQ ProLung Test, or that our business plan is sound;
	●	successfully contract for and establish a commercial supply of components for the manufacture of the IONIQ ProLung Test and the ProLung Scan System;
	●	achieve market acceptance of the IONIQ ProLung Test; and
	●	attract and retain experienced personnel.

If we cannot successfully execute any one of the foregoing, our business may not succeed and your investment will be adversely affected.

We are a small company and may be unable to compete with larger or better-funded companies that promote competitive technologies.

There are a number of competitive technologies currently being developed as well as refinements being made to existing competitive technologies. Technologies being developed or obtaining limited commercialization for the same intended use as our test include, methylated DNA tests, micro RNA tests, panels of proteins and minimally invasive biopsy. These include the current standard of care for the indication to be claimed for the IONIQ ProLung Test; the use of serial chest CT views over a period often ranging from three months to three and one-half years. To the extent that any of these technologies or refinements result in products that successfully address some of the shortcomings of existing products, or result in quality products that are less expensive, safer or outperform existing tests and the IONIQ ProLung Test, future demand for the IONIQ ProLung Test may be reduced or eliminated.

The future market for our products is characterized by rapidly changing technology. Our future financial performance will, in part, be dependent on our ability to develop and manufacture new products or improvements to existing products on a cost-effective basis, to introduce them to the market on a timely basis, and to have them accepted by physicians. We may not be able to keep pace with technological change or to develop viable new products in a timely fashion. Factors that could delay the release of potential products or even cancellation of our plans to produce and market these new products could include delays in research and development, delays in securing future regulatory authorizations, or changes in the competitive landscape.

Many competitors offer a range of products in areas other than those in which we propose to compete, which may make such competitors and their products more attractive to surgeons, hospitals, group purchasing organizations, and other potential customers. Many competitors also have significantly more financial resources than us. Competitive pricing pressures or the introduction of new products by competitors could have an adverse effect on our ability to establish market acceptance for the IONIQ ProLung Test. We cannot predict future markets for the IONIQ ProLung Test or other products, and we may not be able to shift production to other products in the event of a lack of market demand for the IONIQ ProLung Test, leading to an accompanying adverse effect on our profitability.

We are dependent upon contract manufacturers to safely and timely manufacture our products.

If we commercialize our IONIQ ProLung Test, we will need to establish arrangements with contract manufacturers to manufacture, package, label, and deliver our products. Our business will suffer if there are delays or difficulties in establishing relationships with manufacturers to manufacture, package, label, and deliver our products, or if the prices charged by such manufacturers are higher than anticipated. Moreover, contract manufacturers that we may use must adhere to current Good Manufacturing Practices, as required by FDA. If any such manufacturers fail to comply with FDA requirements, they may be unable to manufacture our products. In addition, such manufacturers may fail to manufacture our products in accordance with specifications or may fail to meet delivery timelines, which may cause problems in our customer or distributor relationships and potentially lead to defaults or an obligation to pay damages. If we are unable to obtain or retain third party manufacturing on commercially acceptable terms, we may not be able to commercialize our products as planned. Our dependence upon third parties for the manufacturing of our products may harm our ability to generate significant revenues or acceptable profit margins and our ability to develop and deliver such compliant products on a timely and competitive basis.

Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we rely on third parties to supply the raw materials needed to manufacture our product. Any reliance on suppliers may involve several risks, including a potential inability to obtain critical materials and reduced control over production costs, delivery schedules, reliability and quality. Any unanticipated disruption to a future contract manufacturer caused by problems at suppliers could delay shipment of the IONIQ ProLung Test, increase our cost of goods sold and result in lost sales.

We are dependent upon third parties for marketing and other aspects of our business.

We have limited experience in sales, marketing and distribution of our products and are just beginning the process of developing a sales and marketing organization, which includes an establishment of a distributor network. Our lack of experience could negatively impact our ability to enter into or maintain collaborative arrangements or other third-party relationships which are important to the successful commercialization of our products and potential profitability. We may be unable to establish or maintain adequate sales and distribution capabilities.

In developing a preliminary commercialization plan, much of our strategy for the commercialization of the IONIQ ProLung Test will also rely on us entering into various arrangements with licensors, distributors, and other third parties. We may be unable to enter into necessary distribution and licensing agreements to market the product. In addition, even if we enter into such relationships, we may have limited or no control over the sales, marketing and distribution activities of third parties. Failure to enter into or maintain these arrangements with third parties or failure to develop our own sales and marketing infrastructure could substantially impair or even eliminate our ability to market the IONIQ ProLung Test. Our reliance on collaboration with others may adversely affect our ability to continue to operate, pursue our technology development program, or to achieve profitability.

Any clinical trials that we conduct may not be completed on schedule, or at all, or may be more expensive than we expect, which could prevent or delay regulatory authorization(s) of our products or impair our financial position.

The commencement or completion of any clinical trials that we conduct may be delayed or halted for numerous reasons, including, but not limited to, the following:

	●	the FDA or other regulatory authorities suspend or place on hold a clinical trial, or do not give us the authorization required to start a clinical trial;
	●	the data and safety monitoring committee or applicable hospital institutional ethics review board recommends that a trial be placed on hold or suspended;
	●	fewer patients meet our clinical study criteria and our enrollment rate is lower than we expected;
	●	patients do not return for follow-up as expected;
	●	clinical trial sites decide not to participate or cease participation in a clinical trial;
	●	patients experience adverse side effects or events related to our IONIQ ProLung Test or for unrelated reasons;
	●	third-party clinical investigators do not perform our clinical trials on schedule or consistent with the clinical trial protocol and good clinical practices, or other third-party organizations do not perform data collection and analysis in a timely or accurate manner;
	●	we fail regulatory inspections of our manufacturing facilities requiring us to undertake corrective action or suspend or terminate our clinical trials;
	●	governmental regulations require additional testing not currently contemplated in our pivotal trial or implement administrative actions;
	●	pre-clinical or clinical data are interpreted by third parties in unanticipated ways; or
	●	our trial design is considered inadequate to demonstrate safety and/or efficacy of the product.

Patient enrollment in clinical trials and completion of patient follow-up in clinical trials depend on many factors, including the size of the target patient population, the nature of the trial protocol, the proximity of patients to clinical sites and patient compliance. Delays in patient enrollment or failure of patients to continue to participate in a study may cause an increase in costs and delays or result in the failure of the trial.

Our clinical trial costs will increase if we have material delays in those trials or if we need to perform more or larger trials than planned. Adverse events during a clinical trial could cause us to repeat a trial, terminate a trial or cancel an entire program. Should our clinical development plan be delayed, this could have a material adverse effect on our operations and financial condition.

We engage in related party transactions, which result in a conflict of interest involving our management.

We have engaged in the past, and may continue to engage, in related party transactions. Related party transactions present difficult conflicts of interest, could result in disadvantages to our company and may impair investor confidence, which could materially and adversely affect us. Related party transactions could also cause us to become materially dependent on related parties in the ongoing conduct of our business, and related parties may be motivated by personal interests to pursue courses of action that are not necessarily in the best interests of our company and our stockholders.

IONIQ ProLung Tests may produce false positive and false negative results.

A patient may have a low composite risk score as measured by the IONIQ ProLung Test and still have lung cancer. A low composite risk score does not preclude risk for lung cancer. This patient, however, based upon a false negative IONIQ ProLung Test, may be subject to less stringent clinical vigilance. The IONIQ ProLung Test is to be used in conjunction with all available clinical risk factors and findings including physician/health practitioner judgment. Nonetheless, a false negative result generated from the IONIQ ProLung Test may contribute to a patient not receiving a timely diagnosis of or treatment for existing lung cancer.

By contrast, a patient may have a high composite risk score but not have lung cancer. Such a patient may be subject to greater clinical vigilance or unnecessary invasive procedures, such as biopsy, thus subjecting the patient to greater morbidity and potential mortality due to a falsely positive IONIQ ProLung Test. Again, since the IONIQ ProLung Test is to be used in conjunction with other clinical findings, and not as a stand-alone diagnostic test, such a case would be unlikely. Nonetheless, a false positive result generated from the IONIQ ProLung Test may contribute to a patient receiving unnecessary procedures, such as CT Scans and lung biopsies. False positive and false negative results would likely erode market acceptance of the IONIQ ProLung Test and would thus harm our business, cash flows and operations.

Our clinical studies may produce unfavorable results.

Unfavorable results could prevent the IONIQ ProLung Test from obtaining FDA and other regulatory authorizations. Unfavorable clinical results may also prevent the Company from adequately commercializing the IONIQ ProLung Test in foreign markets such as the European Union which would harm our business, cash flows and operations. The Company may not have a cost-effective resolution to overcome either of these obstacles.

Our success depends upon our ability to effectively market our products.

If the IONIQ ProLung Test does not achieve market acceptance, we will be unable to generate significant revenues. The commercial success of the IONIQ ProLung Test will depend primarily on convincing healthcare providers to adopt and use the IONIQ ProLung Test. To accomplish this, we, together with any other marketing or distribution collaborators, will need to convince members of the medical community the benefits of the IONIQ ProLung Test through, for example, published papers, presentations at scientific conferences, and additional clinical data. Medical providers will not use our product unless we can demonstrate that our product consistently produces results comparable or superior to existing products and has acceptable safety profiles and costs. If we are not successful in these efforts, market acceptance of the IONIQ ProLung Test could be limited. Even if we demonstrate the effectiveness of the IONIQ ProLung Test, medical practitioners may still use other products. If the IONIQ ProLung Test does not achieve broad market acceptance, we will be unable to generate significant revenues, which would have a material adverse effect on its business, cash flows, and results of operations.

We are dependent on key personnel, who may terminate their employment at any time.

Our success depends, in large part, upon the talents and skills of company management and other key personnel. There can be no assurance that we would be able to find suitable replacements for all such personnel or that suitable personnel could be obtained for an amount that we could afford. In the future, a need for additional qualified personnel is expected in order to operate the business successfully. There can be no assurance that we will be able to attract employees of adequate qualification or that we would be able to afford such personnel.

Competition for skilled personnel in our market is intense and competition for experienced scientists may limit our ability to hire and retain highly qualified personnel on acceptable terms. Members of our management, scientific and medical teams may terminate their employment with us on short notice. The loss of the services of any of our executive officers or other key employees could potentially harm our business, operating results or financial condition.

Other medical companies with which we compete for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel, the rate and success at which we can develop and commercialize our product would be limited.

A pandemic, epidemic or outbreak of an infectious disease in the markets in which we operate or that otherwise impacts our facilities or suppliers could adversely impact our business.

If a pandemic, epidemic, or outbreak of an infectious disease, including the recent outbreak of respiratory illness caused by a novel coronavirus (COVID-19) first identified in Wuhan, Hubei Province, China, or other public health crisis were to affect our markets or facilities. Consequences of the coronavirus outbreak are resulting in disruptions in or restrictions on our ability to travel, supply chains and clinical trial participation. If such an infectious disease broke out at our office, facilities or work site, our operations may be affected significantly, our productivity may be affected, our ability to complete projects. In response to the COVID-19 situation, federal, state and local governments (or other governments or bodies) are considering placing, or have placed, restrictions on travel and conducting or operating business activities. At this time those restrictions continue to be very fluid and evolve. We have been and will continue to be impacted by those restrictions. Given that the type, degree and length of such restrictions are not known at this time, we cannot predict the overall impact of such restrictions on us. As such, the impact these restrictions may have on our financial position, operating results and liquidity cannot be reasonably estimated at this time, but the impact may be material. In addition, due to the speed with which the COVID-19 situation is developing and evolving, there is uncertainty around its ultimate impact on public health, business operations and the overall economy; therefore, the negative impact on our financial position, operating results and liquidity cannot be reasonably estimated at this time, but the impact may be material.

Risks Related to Our Regulatory and Legal Environment

We must obtain regulatory clearance or approval in the US and other non-European Union markets to be able to commence marketing and sales in those markets.

In many countries, we are required to obtain government clearance or approval before we can market and sell a medical device like the IONIQ ProLung Test. Obtaining the necessary clearance or approval is a complex, costly, and time-consuming process, which differs from country-to-country. Failure to comply with the premarket authorization requirements of a country can result in serious penalties, including fines, recalls, seizure of product, suspension of sales, refusal to grant other approvals or clearances, increased requirements for quality control or (in severe cases) criminal prosecution. The imposition of any of the afore-mentioned penalties would adversely affect our business.

We have received a CE Mark for the marketing of the IONIQ ProLung Test in the European Union. We are seeking clearance to sell the IONIQ ProLung Test in the US and plan to seek clearance in other markets. Each market has unique regulatory requirements. In the US, FDA marketing clearance will be required before the IONIQ ProLung Test may be marketed in the US. We expect to be subject to the premarket notification or de novo clearance pathway, but may be subject to premarket approval, which would substantially lengthen (and substantially increase the costs associated with) the regulatory process beyond that which is currently anticipated. As with the FDA review process, there are numerous risks associated with the review of medical devices by foreign regulatory agencies. The foreign regulatory agencies may request additional data to demonstrate the clinical safety and efficacy of a product. It is possible that we may not obtain the clearance or approval required to market the IONIQ ProLung Test in the US or another significant potential market, which would harm our long-term revenue potential.

Even if marketing clearance (or approval) is granted, such clearance (or approval) may include significant limitations on the indicated use(s) for which the product may legally be marketed – i.e., the clearance may not allow us to make the type of claims that we believe we need to make for the IONIQ ProLung Test to be commercially viable. Delays in obtaining regulatory clearance(s) or approval(s) would also harm our financial condition. A failure to obtain required clearances for our desired indication(s) in a timely fashion, particularly in the US, would significantly harm our long-term ability to continue as a going concern.

Even if we receive regulatory clearance or approval for the IONIQ ProLung Test, we still may not be able to successfully commercialize it and the revenue that we generate from its sales, if any, may be limited.

The commercial success of the IONIQ ProLung Test will depend on its acceptance by the medical community, including physicians, patients and health care payors. The degree of market acceptance of the IONIQ ProLung Test will depend on a number of factors, including:

	●	demonstration of clinical safety, efficacy, and utility;
	●	relative convenience and ease of use;
	●	the prevalence and severity of any adverse effects;
	●	the willingness of physicians to order the IONIQ ProLung Test and of the target patient population to try new medical devices;
	●	the introduction of any new products that in the future may become available to compete with the IONIQ ProLung Test;
	●	pricing and cost-effectiveness;
	●	the inclusion or omission of the IONIQ ProLung Test in applicable treatment guidelines;
	●	the effectiveness of our or any future collaborators’ sales and marketing strategies;
	●	limitations or warnings contained in FDA-cleared (or approved) labeling;
	●	our ability to obtain and maintain sufficient third-party coverage and reimbursement from government health care programs, including Medicare and Medicaid, private health insurers and other third-party payors; and
	●	the willingness of patients to pay out-of-pocket in the absence of third-party coverage or adequate reimbursement.

In addition, even if we obtain regulatory clearances or approvals, the timing or scope of any clearances or approvals may prohibit or reduce our ability to commercialize the IONIQ ProLung Test successfully. For example, if the approval process takes too long, we may miss market opportunities and give other companies the ability to develop competing products or establish market dominance. Any regulatory clearance (or approval) we ultimately obtain may be limited or subject to restrictions or post-market commitments that render the IONIQ ProLung Test not commercially viable. For example, third-party payers may deny coverage for the test or set reimbursement for the IONIQ ProLung Test procedure at a rate that is insufficient to cover provider costs, or regulatory authorities may grant clearance or approval contingent on ProLung’s performance of costly post-marketing clinical trials. Moreover, product clearances and approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial success of the IONIQ ProLung Test.

If we obtain FDA clearance, we will be subject to Medical Device Reporting (“MDR”) requirements, which may lead to inquiries, injunctions, or liabilities.

Under the FDA MDR regulations, medical device manufacturers are required to submit information to the FDA when they receive a report or become aware that a device has caused or may have caused or contributed to a death or serious injury or has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medical devices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell to the regulatory agency, or other Competent Authority, in whose jurisdiction the incident occurred. Were we to learn of a reportable adverse event, we would submit the required information to the relevant regulatory agency, to which the agency may respond with additional request(s) for information if the agency has any questions.

Malfunction of our products could result in future voluntary corrective actions, such as recalls, including corrections, or customer notifications, or agency action, such as inspection or enforcement actions. If malfunctions do occur, we may be unable to correct the malfunctions adequately or prevent further malfunctions, in which case we may need to cease distribution of the affected products, initiate voluntary recalls, and redesign the products. Regulatory authorities may also take actions against us, such as ordering recalls, imposing fines, or seizing the affected products. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results.

Existing US regulatory laws and cost-saving initiatives may harm our revenues and create additional expenses.

To the extent that we market the IONIQ ProLung Test in the US, federal healthcare reform may adversely affect the results of our domestic operations. The Patient Protection and Affordable Care Act, or the Affordable Care Act, was enacted in March 2010. The Affordable Care Act included several provisions intended to reduce the volume of medical procedures, which, in turn, could result in reduced demand for our products and increased downward pricing pressure. While the Affordable Care Act is intended to expand health insurance coverage to uninsured persons in the US, the impact of any overall increase in access to healthcare on potential sales of the IONIQ ProLung Test is uncertain at this time. Further, we cannot predict with any certainty what other impact the Affordable Care Act may have on our business.

Recently proposed healthcare reform measures could hinder or prevent the commercial success of our products.

The pricing and reimbursement environment may change in the future and become more challenging as a result of any of one several possible regulatory developments, including policies advanced by the United States government, new healthcare legislation, repeal or reform of the Affordable Care Act, or fiscal challenges faced by government health administration authorities. The US government has shown significant interest in pursuing healthcare “reform” and reducing healthcare costs. For example, aggregate reductions to Medicare payments to providers of up to 2% per fiscal year were implemented starting in 2013. Any government-adopted reform measures that further decrease the amount of reimbursement our customers receive from governmental and other third-party payers could potentially adversely affect our business.

We will be subject to healthcare fraud and abuse law regulations.

Our operations may be directly or indirectly affected by various broad federal, state or foreign healthcare fraud and abuse laws. In particular, the US federal Anti-Kickback Statute prohibits any person from knowingly and willfully soliciting, receiving or providing any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, in return for referring an individual for the furnishing or arranging for the furnishing of any item or service for which payment may be made in whole or in part under a Federal health care program, or in return for the ordering, leasing, purchasing, or arranging for or recommending the ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made in whole or in part under federal healthcare programs, such as the Medicare and Medicaid programs. We are also subject to the fraud and abuse provisions of the US federal HIPAA statute, which created federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program, willfully obstructing a criminal investigation of a health care offense, or making false statements or concealing a material fact relating to payment for health-care benefits, items or services, and federal “sunshine” laws that require transparency regarding financial arrangements with healthcare providers, such as the reporting and disclosure requirements imposed by the Affordable Care Act on certain medical device manufacturers regarding any “transfer of value” made or distributed to prescribers and other healthcare providers.

In addition, the US federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states have also enacted laws modeled after the federal False Claims Act.

Many states and other countries have also adopted laws similar to 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, as well as laws that restrict our marketing activities with physicians, and require us to report consulting and other payments to physicians. Some states and other countries mandate implementation of commercial compliance programs to ensure compliance with these laws. We also are subject to foreign fraud and abuse laws, which vary by country.

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 now or in the future, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.

Our clinical study designs have not been reviewed by the FDA.

Our PL-208 and PLW-216 clinical studies were designed without input from the FDA. We have received significant comments from the FDA, some but not all of which have been resolved. There can be no assurance that the FDA will approve the design of PL-208 and PLW-216 or any future study, or agree that the results generated in our PL-208 and PLW-216 trial is sufficient for FDA to approve or clear the IONIQ ProLung Test for our desired indication for use. Even if our clinical studies produce favorable results, the FDA may refuse regulatory clearance and or require additional research causing delays in the launch and commercialization of the IONIQ ProLung Test in the US.

Our clinical studies have resulted in statistically significant variability and the results may be insufficient to gain marketing clearance from the FDA.

Our clinical studies may produce unfavorable results which could prevent or delay ProLung from obtaining FDA and other regulatory clearances. In November 2018, we reported our PL-209 study results indicating day-to-day variability is repeatable; however, same-day variability is statistically significant with a 2% difference in scores though the clinical impact is unclear. In January 2019, we announced preliminary results for our PL-208 study. In the Validation Set (n=174 subjects), the IONIQ ProLung Test demonstrated a sensitivity of 68%, specificity of 49%, Positive Predictive Value (PPV) of 70%, Negative Predictive Value (NPV) of 47% and an Accuracy of 61%. In, the fall of 2019 we announced the results of PLW-216. In the study of 486 subjects with 418 effective, the IONIQ ProLung Test returned results of 84% sensitivity, 73% specificity, 78% Positive Predictive Value (PPV) and 80% Negative Predictive Value (NPV). The performance from PL-208, PL-209 and PLW-216 may be insufficient to gain marketing clearance from the FDA.

Risks Related to Our Intellectual Property

We may be unable to protect our intellectual property rights, which are important to the potential value of our products and company.

We have obtained patent protection for aspects of the IONIQ ProLung Test in a limited number of jurisdictions, and there is no guarantee that such protection will be available for the IONIQ ProLung Test in all jurisdictions, or, that once obtained, we would be able to enforce such rights. Disputes may arise between us and others as to the scope, validity and ownership rights of patents. Any defense of patents could prove to be costly and time consuming and we may not be in a position, or may deem it unadvisable, to carry on such a defense.

There can be no assurance that any patent applications that we or our licensors file will result in patents being issued or that, if issued, the patents will afford protection against competitors with similar technology. There can also be no assurance that any patents issued to us or that we license will not be infringed on or circumvented by others, or that others will not obtain patents that we would need to license or circumvent. Our patents may not contain claims that are sufficiently broad to prevent others from using our technologies or developing competing products. Competitors may be able to use technologies in competing products that perform substantially the same as our technologies but avoid infringing on our patent claims. Under these circumstances, our patents would be of little commercial value.

Additionally, there can be no assurance that patents, even after issuance, will be upheld by applicable courts. There can be no assurance that licenses, which might be required for our processes or products, would be available on reasonable terms, or that patents issued to others would not prevent us from developing and marketing its products. To the extent that we also rely on un-patented trade secrets, there can be no assurance that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technology. Disclosure of our trade secrets would impair our competitive position and adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. Further, to the extent that our employees, consultants or contractors use trade secret technology or know-how owned by others in their work for us, disputes may arise as to the ownership of related inventions.

We may incur significant costs and liability if we infringe, or are accused of infringing on, the intellectual property rights of others.

We may incur significant liability if we infringe the patents and other proprietary rights of third parties, including damages, inability to sell or license the IONIQ ProLung Test without obtaining a license from the patent holder, which may not be available at commercially reasonable terms or at all, and we may have to redesign the IONIQ ProLung Test so that it does not infringe on the third-party patent, which redesign may not be possible or could require substantial funds or time. Although no third party has asserted a claim of infringement against us, in the event that our technologies infringe or violate the patent or other proprietary rights of third parties, we may be prevented from pursuing product development, manufacturing or commercialization of any product that uses these technologies. There may be patents held by others of which we are unaware that contain claims that our product or operations infringe. In addition, given the complexities and uncertainties of patent laws, there may be patents of which we may ultimately be held to infringe, particularly if the claims of the patent are determined to be broader than we believe them to be. Even if we are ultimately successful in our defense of an infringement case, the costs of litigation would significantly harm our business.

We may need to market the IONIQ ProLung Test under a different name in the EU to avoid the risk of infringement.

We are aware of a company that markets an assay to be used as a liquid biopsy test for lung cancer detection under the name Epi proLung, which is trademarked in the EU. If we market the IONIQ ProLung Test in the EU, we may be subject to the risk of infringement. If we determine, at the time we choose to market the IONIQ ProLung Test in the EU, that we may infringe on this trademark, we might need to change the name under which we market the IONIQ ProLung Test in the EU.

Parts, components, and software incorporated in the IONIQ System may become obsolete.

The IONIQ System consists of both custom and off the shelf parts and software. As off-the-shelf components age, they may become obsolete requiring the Company to procure, test and validate replacement components, parts and software for the IONIQ System.

Risks Related to Capital Stock

Our SEC Reports contain projections and forward-looking statements that may not prove to be accurate.

Our SEC Reports, including those delivered herewith, contain projections that are based on our assumptions and judgments as of the date of such reports concerning future events and are subject to significant uncertainties and contingencies, many of which are beyond our control. Our actual results may materially differ from the results we have projected. In addition, our SEC Reports contain forward-looking statements that involve known and unknown risks and uncertainties. All statements other than those of historical facts, including those regarding business strategy, plans and objectives of management, projected costs, and expected benefits are forward-looking statements. These forward-looking statements are based on information and expectations as of the date of the respective SEC Report. Important factors that could cause our results to differ materially from expectations include those set forth in this “Risk Factors” section and elsewhere in our SEC Reports. We disclaim any obligation or intent to update these forward- looking statements.

There is no trading market for our common stock, and it is possible that no trading market will develop.

There is currently no public trading market for the Company’s common stock, and there is no assurance that a public market for the Company’s common stock will exist in the future. We do not currently meet the listing requirements of the Nasdaq Stock Market or any other exchange. We do meet the requirements for listing on an over- the-counter market; however, an application for quotation in the over-the-counter market must be submitted by one or more market makers who: 1) are approved by the Financial Industry Regulatory Authority, 2) who agree to sponsor the security, and 3) who demonstrate compliance with SEC Rule 15(c)2-11 before initiating a quote in a security on the over-the-counter market.

If our common stock commences trading in the over-the-counter market, it will likely be subject to penny stock rules, which may restrict liquidity.

If our common stock becomes tradable in the secondary market, it may be subject to the penny stock rules adopted by the SEC that require brokers to provide extensive disclosure to their customers prior to executing trades in penny stocks. These disclosure requirements may cause a reduction in the trading activity of the Company’s common stock, which in all likelihood would make it difficult for our shareholders to sell their securities. Penny stocks generally are equity securities with a price of less than $5.00 (other than securities registered on certain national securities exchanges or quoted on the Nasdaq Stock Market). Penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. The broker-dealer must also make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These requirements may have the effect of reducing the level of trading activity, if any, in the secondary market for a security that becomes subject to the penny stock rules. The additional burdens imposed upon broker-dealers by such requirements may discourage broker-dealers from effecting transactions in our securities, which could severely limit their market price and liquidity of our securities. These requirements may restrict the ability of broker-dealers to sell the Company’s common stock and may affect the Purchaser’s ability to resell the common stock.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could significantly reduce the value of our shares to a potential acquirer or delay or prevent changes in control or changes in our management without the consent of our Board of Directors. The provisions in our charter documents include the following:

	●	a classified Board of Directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our Board of Directors;

	●	no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

	●	the exclusive right of our Board of Directors to elect a director to fill a vacancy created by the expansion of the Board of Directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our Board of Directors;

	●	the prohibition on removal of directors without cause;

	●	the ability of our Board of Directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

	●	the ability of our Board of Directors to alter our bylaws without obtaining stockholder approval;

	●	the requirement that a special meeting of stockholders may be called only by the President of the Company or by the Board of Directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors.

In addition, these provisions would apply even if we were to receive an offer that some stockholders may consider beneficial.

We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, the Board of Directors has approved the transaction.

We are subject to various regulatory regimes, and may be adversely affected by inquiries, investigations and allegations that we have not complied with governing rules and laws.

In light of our status as a reporting company and the early stage of our business, we are subject to a variety of laws and regulatory regimes in addition to those applicable to all businesses generally. For example, we are subject to the reporting requirements applicable to U.S. reporting issuers, such as the Sarbanes-Oxley Act of 2002, and certain state and provincial securities laws. In addition, because we are in an early stage of development and intend on issuing securities to raise capital and use acquisitions for growth, our actions will be governed by state and federal securities laws and laws governing the issuance of securities, which are complex. In connection with such laws, we may be subject to periodic audits, inquiries, and investigations. Any such audits, inquiries, and investigations may divert considerable financial and human resources and adversely affect the execution of our business plan.

Through such audits, inquiries, and investigations, we, or a regulator, may determine that we are out of compliance with one or more governing rules or laws. Remedying such non-compliance diverts additional financial and human resources. In addition, in the future, we may be subject to a formal charge or determination that we have materially violated a governing law, rule, or regulation. We may also be subject to lawsuits as a result of alleged violation of the securities laws or governing corporate laws. Any charge or allegation, and particularly any determination, that we had materially violated a governing law would harm our ability to enter into business relationships, recruit qualified officers and employees, and raise capital.

If a market develops for our common stock, we expect the market price to be volatile.

The market prices of securities of smaller companies tend to be highly volatile. If a market develops for our common stock, of which there can be no assurance, our stock price may change dramatically as the result of announcements of our quarterly results, slow revenue growth, absence of profits, the rate of our expansion, significant litigation or other factors or events that would be expected to affect our business or financial condition, results of operations, and other factors specific to our business and future prospects. In addition, the market price for our common stock may be affected by various factors not directly related to our business, including the following:

	●	intentional manipulation of our stock price by existing or future stockholders;

	●	short selling of our common stock or related derivative securities;

	●	a single acquisition or disposition, or several related acquisitions or dispositions, of a large number of our shares of common stock;

	●	the interest, or lack of interest, of the market in our business sector;

	●	the adoption of governmental regulations and similar developments in the U.S. or abroad that may affect our ability to offer our products and services or affect our cost structure; and

	●	economic and other external market factors, such as a general decline in market prices due to poor economic indicators or investor distrust.

We have never paid, and do not intend to pay in the future, dividends on our common stock.

We have never declared nor paid any cash dividends on our capital stock. We currently intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future. It is unlikely that investors will derive any current income from ownership of our stock. This means that the potential for economic gain from ownership of our stock depends on appreciation of our stock price and will only be realized by a sale of the stock at a price higher than the purchase price.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We currently maintain a corporate office at 350 W. 800 N., Suite 214, Salt Lake City, Utah 84103. We currently lease this property for $3,600 a month. The lease is through April 30^th 2022. This location is approximately 3,635 square feet of office space.

Item 3. Legal Proceedings

We know of no existing or pending legal proceedings against us, nor are we involved as a plaintiff in any proceeding or pending litigation. There are no proceedings in which any of our directors, officers or any of their respective affiliates, or any beneficial stockholder is an adverse party or has a material interest adverse to our interest.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchasers of Equity Securities Market Price of and Dividends on the Registrant’s Common Equity and Related Stockholder Matters.

(a) Market Information

Our common stock is not listed or traded on any exchange or other market.

(b) Holders

As of April 11, 2022, there are 4,521,011 shares outstanding held by approximately 800 stockholders of record.

We have not declared or paid dividends on our common stock since our formation, and we do not anticipate paying dividends in the foreseeable future. Declaration or payment of dividends, if any, in the future, will be at the discretion of our Board of Directors and will depend on our then current financial condition, results of operations, capital requirements and other factors deemed relevant by the Board of Directors. There are no contractual restrictions on our ability to declare or pay dividends.

(d) Securities Authorized for Issuance under Equity Compensation Plans

In April 2017 the Board of Directors approved the ProLung Inc. Stock Incentive Plan (the “Plan”). The shareholders approved the Plan in July 2017. The Plan authorizes the Board Compensation Committee to grant incentive stock options, non-incentive stock options, stock bonuses, restricted stock, and performance-based awards to directors, officers, employees and non-employee agents, consultants, advisers, and independent contractors of the Company or any parent or subsidiary of the Company. The following table sets forth certain information with respect to the Plan and any other plans plan as of December 31, 2021:

Plan Category	Number of securities to be issued upon exercise of outstanding options, warrants and rights (a)		Weighted-average exercise price of outstanding options, warrants and rights		Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a))
Equity compensation plans approved by security holders		771,788	$	5.39		0
Equity compensation plans not approved by security holders		1,344,985	$	5.25		N/A
Total		2,116,773	$	5.30		0

The total number of initial shares of Common Stock authorized for issuance under the Plan was 500,000 shares; the authorized shares will automatically increase on January 1st of each year, for ten consecutive years, commencing on January 1, 2018, by the lesser of (i) 40,000 shares of Common Stock (i.e., 8% of the shares of the shares originally authorized to be issued), or (ii) such number of shares of common stock (if any) the Board may earlier designate in writing. If the automatic increases are not limited by the Board, there will be 900,000 shares of common stock authorized under the Plan in January 1, 2027.

Overview

We believe the IONIQ ProLung Test for lung cancer, in conjunction with the discovery of a nodule by CT scan, provides a more rapid assessment of the risk of malignancy, which must be determined prior to biopsy. Since a lung biopsy is invasive and may require life threatening thoracic surgery, physicians, patients, and insurance companies typically delay biopsy and therapy until the risk of malignancy outweighs the risk of further diagnostic procedures. For these patients, the delay reduces the treatment opportunity window and may cause sustained emotional trauma.

Results of Operations

The following discussion is included to describe our consolidated financial position and results of operations. The consolidated financial statements and notes thereto contain detailed information that should be referred to in conjunction with this discussion.

Fiscal Year Ended December 31, 2021, compared to Fiscal Year Ended December 31, 2020

Revenue and Cost of Revenue.

During the year ended December 31, 2021 or 2020, we had no revenue.

Operating Expenses

Research and Development Expense. Research and development expense for the year ended December 31, 2021 was 761,052 compared to research and development expense of $738,734 for the year ended December 31, 2020; representing an increase of $22,318. The nominal increase was due to additional consulting in support of our FDA submission. We would expect our research and development costs to remain relatively constant during 2022.

Selling, General and Administrative Expense. Selling, general and administrative expense for the year ended December 31, 2021 was $1,722,044 compared to selling, general, and administrative expense of $1,330,926 for the year ended December 31, 2020, representing an increase of $391,118. This increase was due to increases in fundraising activities, consulting in support of our FDA submission, stock compensation, and insurance rates in 2021.

Other Expense. Other expense for the year ended December 31, 2021 was $1,131,933 compared to $657,956 the year ended December 31, 2020. The increase costs consist of the following:

Interest Expense – Interest increased in 2021 to ($1,268,823) from ($783,965) in 2020 due to increased debt levels and the associated amortization of additional loan costs.

Gain/ Loss on Debt Extuingsuishment –.

In April 2020, the Company entered into an SBA Loan Paycheck Protection Program (the “PPP”) under the recently enacted Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Company received total proceeds of $126,000 from the SBA Loan. Subject to certain conditions, the SBA Loan may be forgiven in whole or in part by applying for forgiveness pursuant to the CARES Act and the PPP. The Company received notice in November 2020 the loan had been forgiven and recorded the forgiveness as gain from debt extinguishment. During 2021, the Company was able to settle various obligations at amounts less than originally accrued thus causing a gain on debt extinguishment.

Liquidity and Capital Resources

The following is a summary of our key liquidity measures at December 31, 2021 and 2020:

	December 31,
	2021			2020

Cash	$	745,003		$	185,126

Current assets		745,003			190,553
Current liabilities		(12,435,011	)		(1,730,413	)

Working capital deficit	$	(11,690,008	)	$	(1,539,860	)

We need additional capital to continue our operations. We issued $3,448,779 in convertible notes during the year ended December 31, 2021. In order for us to continue operations we will need additional capital which will require us to issue equity securities, debt securities and rights to acquire equity securities. We have no existing commitment to provide capital, and given our early stage of development, we may be unable to raise sufficient capital when needed and, in any case, will likely be required to pay a high price for capital.

Our future capital requirements and adequacy of available funds will depend on many factors including:

	●	Our ability to find a commercial market for our IONIQ ProLung Test and obtain needed regulatory clearance
	●	Our financial results;
	●	the cost and availability of capital generally; and
	●	the occurrence of unexpected adverse expenses or events.

In March 2018, we began issuing 8% convertible promissory notes (“convertible notes”). The convertible notes are unsecured. Principal and accrued interest were originally set to mature in March 31, 2022; however, these notes, along with our other notes were amended in March 2022 to extend maturity until September 30, 2023. The holder of the convertible note is entitled, at its option, to convert all, or any portion of the outstanding principal and interest, into shares of our common stock at conversion prices ranging from $3.20 to $10.53 per share. Interest accruing from the date of issuance to the conversion date shall be paid on the maturity date. Through December 31, 2021, we have issued $10,457,022 in convertible promissory notes.

In conjunction with receiving these proceeds we paid a placement agent $223,575 in loan fees. We also paid $342,732 to settle a convertible loan that was due.

We received $126,000 in proceeds pursuant to a PPP loan CARES Act which was forgiven in November 2020. Other financing activities included a receipt of $4,893 related to the exercise of warrants and a $45,000 payment related to our research and development note payable.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and reported amounts of revenues and expenses during the reporting periods. We evaluate our estimates on an on-going basis. We base our estimates on historical experience and on other assumptions that are believed to be reasonable under the circumstances. However, future events may cause us to change our assumptions and estimates, which may require adjustment. Actual results could differ from these estimates. We have determined that for the periods reported in this Annual Report on Form 10-K the following accounting policies and estimates are critical in understanding our financial condition and results of operations.

Long-lived Assets – Long-lived assets, including property and equipment, and intangible assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of the long-lived asset or asset group. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value.

Stock-based Compensation – The Company measures the cost of employee and consulting services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The awards issued are valued using a fair value-based measurement method. The resulting cost is recognized over the period during which an employee or consultant is required to provide services in exchange for the award, usually the vesting period.

Emerging Growth Company – We are an “emerging growth company” under the federal securities laws and will be subject to reduced public company reporting requirements. 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. Although we have not delayed the adoption of any accounting standards, we may choose to take advantage of the extended transition period for complying with new or revised accounting standards in the future.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

Not applicable.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable assurance of achieving the desired control objectives, and we necessarily are required to apply our judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures.

Our management, including our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2021, and concluded that the disclosure controls and procedures were not effective, because certain deficiencies involving internal controls constituted material weaknesses as discussed below. The material weaknesses identified did not result in the restatement of any previously reported financial statements or any other related financial disclosure, nor does management believe that it had any effect on the accuracy of our financial statements for the current reporting period.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with GAAP. Because of inherent limitations, a system of internal control over financial reporting may not prevent or detect misstatements. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate due to change in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, including our principal executive officer and principal accounting officer, conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (2013). Based on its evaluation, our management concluded that there are material weaknesses in our internal control over financial reporting and therefore the internal controls are considered not effective. A material weakness is a deficiency, or a combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. As of December 31, 2021, the following material weaknesses existed:

The Company did not maintain effective entity-level internal controls as defined by the framework issued by COSO. Specifically, the Company did not effectively segregate certain accounting duties due to the small size of the Company’s accounting staff. Due to this material weakness, management has concluded that our internal controls over financial reporting were not effective as of December 31, 2021.

In order to mitigate these material weaknesses to the fullest extent possible we engage a third-party accounting firm to provide additional expertise in accounting. If at any time, we determine a new control can be implemented to mitigate these risks at a reasonable cost, it is implemented as soon as possible.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to Commission rules that permit the Company to provide only management’s report in this annual report.

This report shall not be deemed to be filed for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, and is not incorporated by reference into any filing of the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred in the year ended December 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Board Composition

Our bylaws provide that the Board of Directors shall consist of one or more members, with such number to be determined by the Board of Directors. The whole Board of Directors currently consists of seven members. In accordance with our amended and restated certificate of incorporation, our Board of Directors is divided into three classes. At each annual general meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors will be divided among the three classes as follows:

	●	The Class I directors are David Nielsen, Rich McKeown and Jared Bauer. Their terms will expire at the 2021 annual meeting of stockholders tentatively slated for June 2022

	●	The Class II directors are Don Patterson and Michael Garff. Their terms will expire at the 2022 annual meeting of stockholders

	●	The Class III directors are Jim Hogan and Aaron Dorny. Their terms will expire at the 2023 annual meeting of stockholders

We expect that any additional directorships resulting from an increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. 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 in control.

Director Independence

Our Board of Directors has undertaken a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board of Directors has determined that Jim Hogan, David Nielsen, and Rich McKeown representing three of our seven directors, do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined in the Listing Rules of the Nasdaq Stock Market. The remaining Board of Directors have determined that Jared Bauer (CEO), Michael Garff (COO), Aaron Dorny and Don Patterson are not independent under the applicable rules and regulations of the SEC, respectively. In making this determination, our Board of Directors considered the current and prior relationships that each non-employee director has with our company 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.

Board Committees

Our Board of Directors has established an audit committee, a compensation committee a nominating and governance committee and a science and technology committee. Our Board of Directors may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board of Directors. Each committee has adopted a written charter which we post on our website at www.prolunginc.com.

Audit Committee

The audit committee is responsible for assisting our Board of Directors in its oversight of the integrity of our financial statements, the qualifications and independence of our independent auditors and our internal financial and accounting controls. The audit committee has direct responsibility for the appointment, compensation, retention (including termination) and oversight of our independent auditors, and our independent auditors report directly to the audit committee. The audit committee also prepares the audit committee report that the SEC requires to be included in our annual proxy statement.

Our audit committee consists of Don Patterson (chair), Aaron Dorny and Michael Garff. Our Board of Directors has determined that Mr. Patterson, Mr. Dorny and Mr. Garff are independent under Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The chair of our audit committee is Mr. Patterson. Our Board of Directors has determined that Mr. Patterson is an “audit committee financial expert” as such term is currently defined in Item 407(d)(5) of Regulations S-K. Our Board of Directors has also determined that each member of our audit committee can read and understand fundamental financial statements, in accordance with applicable requirements. In arriving at these determinations, the Board of Directors has examined each audit committee member’s scope of experience and the nature of their employment in the corporate finance sector.

Finance and Compensation Committee

The compensation committee approves the compensation objectives for the Company, the compensation of the chief executive officer and approves, or recommends to our Board of Directors for approval, the compensation for other executives. The compensation committee reviews all compensation components, including base salary, bonus, benefits and other perquisites.

Our compensation committee consists of Jim Hogan (chair), David Nielsen and Rich McKeown. Our Board of Directors has determined that Mr. Hogan, Mr. Nielsen and Mr. McKeown are independent and are “non-employee directors” as defined in Rule 16b-3 promulgated under the Exchange Act and are “outside directors” as that term is defined in Section 162(m) of the US Internal Revenue Code of 1986, as amended, or Section 162(m). The chair of our compensation committee is Mr. Hogan.

Code of Ethics

We have adopted a written code of business conduct and ethics that applies to all our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer or controller, or persons performing similar functions, and agents and representatives. The full text of our code of business conduct and ethics is posted on our website at www.prolunginc.com. The nominating and governance committee of our Board of Directors will be responsible for overseeing our code of business conduct and ethics and any waivers applicable to any director, executive officer or employee. We intend to disclose future amendments to certain provisions of our code of business conduct and ethics, or waivers of such provisions applicable to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and agents and representatives, on our website identified above.

Involvement in Legal Proceedings

To the best of our knowledge, four of our former directors and our current CEO have, during the past ten years, been involved in legal proceedings described in subparagraph (f) of Item 401 of Regulation S-K.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the Company’s officers, directors and persons who own more than 10% of the Company’s common stock to file reports concerning their ownership of common stock with the SEC and to furnish the Company with copies of such reports. Based upon the Company’s review of the reports required by such persons and amendments thereto furnished to the Company, the Company believes that all reports required to be filed pursuant to Section 16(a) of the Exchange Act have been timely filed other than as follows.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Certain Relationships and Related Transactions

Other than compensation arrangements described herein, since January 1, 2020, there has not been, nor is there currently proposed, any transaction or series of similar transactions to which we were or are a party in which the amount involved exceeds the lesser of (1) $120,000 and (2) one percent of the average of our total assets at year-end for the last two completed fiscal years, in which any director, executive officer or beneficial holder of more than 5% of any class of our voting securities or members of such person’s immediate family or household had or will have a direct or indirect material interest, other than the transactions described below.

Director Independence

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of ProLung, Inc.:

Opinion on the Financial Statements

We have audited the accompanying balance sheets of ProLung, Inc. (“the Company”) as of December 31, 2021 and 2020, the related statements of operations, stockholders’ deficit, and cash flows for each of the years in the two-year period ended December 31, 2021 and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and 2020, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph Regarding Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has incurred substantial and recurring losses to date from operations, continues to have a stockholders’ deficit and is currently dependent on debt and equity financing, which creates substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, 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.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Sadler, Gibb & Associates, LLC

We have served as the Company’s auditor since 2020.

Notes to Financial Statements

Note 1 – Organization and Summary of Significant Accounting Policies

Organization – ProLung, Inc. (the “Company”), is a Delaware corporation that was incorporated on November 22, 2004 and is doing business as “ProLung.” In May 2020, the Company announced a dba IONIQ Sciences. The Company’s headquarters are located in Salt Lake City, Utah. The Company’s business is the marketing and sales of precision predictive analytical medical devices specializing in lung cancer. The Company’s principal activities are primarily developing products, seeking FDA clearance for its products, developing markets and securing strategic alliances and obtaining financing.

Going Concern – The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company has generated minimal revenues thus far from its operations and no revenue during the current period. Until the Company receives Food and Drug Administration (“FDA”) approval, the Company will not achieve its planned level of operations in the United States. The Company does have a Conformité Européene or CE mark for Europe and has licensed a portion of its technology to an entity located in China. The Company has incurred substantial and recurring losses to date from operations, continues to have a stockholders’ deficit and is currently dependent on debt and equity financing. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of one year from the issuance of these financial statements. The accompanying financial statements do not include any adjustments that might result relating to the recoverability and classification of the asset carrying amounts or the amount and classification of liabilities that might result from the outcome of this risk and uncertainty.

The ability of the Company to continue as a going concern is dependent on the Company successfully obtaining additional funding, developing products that can be sold profitably, and generating cash through operating activities. Management’s plans include issuing equity or debt securities to fund capital requirements and developing ongoing operations.

Use of Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

Concentration of Credit Risk – Financial instruments that potentially subject the Company to a concentration of credit risk consists principally of cash. The Company has approximately $495,000 in cash balances during the year ended December 31, 2021 in excess of federally insured limits. The Company places its cash with a high credit quality financial institution.

Fair Value of Financial Instruments – For the notes payable and convertible debentures classified as long-term liabilities, the estimated fair value is approximately equal to the carrying value based on the interest rates and other terms of debt.

Cash and Cash Equivalents – The Company considers all unrestricted highly liquid investments purchased with a maturity of three months or less to be cash equivalents. The Company had no cash equivalents as of December 31, 2021 and 2020.

Property and Equipment – Property and Equipment is stated at cost and depreciated using the straight-line method over useful lives of 3 to 5 years. Leasehold improvements are amortized over the shorter of the life of the lease or the service life of the improvements. Maintenance, repairs, and renewals that neither materially add to the value of the property nor appreciably prolong its life are charged to expense as incurred. Gains or losses on dispositions of property and equipment are included in the results of operations.

Intangible Assets – As further discussed in Note 3 to these financial statements, intangible assets consist of rights to certain patent applications acquired in December 2015 under a Patent Assignment Agreement. These intangible assets are being amortized over an estimated useful life of eighteen years, with periodic evaluation for impairment.

Impairment or Disposal of Long-Lived Assets - Long-lived assets are reviewed for impairment when facts and circumstances indicate that the carrying value of the asset may not be recoverable. When necessary, impaired assets are written down to estimated fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates. We did not record an asset impairment charge for either of the years ended December 31, 2021 and 2020.

ProLung, Inc.

Notes to Financial Statements

Research and Development – The Company expenses research and development costs as incurred. Research and development costs primarily consist of clinical study costs, consulting fees, compensation of employees related to activities to obtain regulatory approval for the Company’s devices, and materials and supplies.

Stock-based Compensation – The Company measures the cost of employee and non-employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and to recognize it as compensation expense over the period the employee and non-employee is required to provide service in exchange for the award, usually the vesting period.

Income Taxes – The Company accounts for income taxes under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for operating loss and tax credit carry-forwards. Deferred income tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The Company has established a valuation allowance to reduce deferred income tax assets to their realizable values based on whether it is more likely than not that such deferred income tax assets will be realized. At December 31, 2021 and 2020, the Company has recorded a full valuation allowance against the net deferred tax assets related to temporary differences and operating losses because there is significant uncertainty as to the realizability of the deferred tax assets.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company currently believes that all significant filing positions are above this threshold and therefore, the Company has no significant reserves for uncertain tax positions and no adjustments to such reserves are required by generally accepted accounting principles. No interest or penalties have been levied against the Company and none are anticipated; therefore, no interest or penalty has been included in our provision for income taxes in the statements of operations.

Basic and Diluted Loss Per Share – The Company computes basic loss per share by dividing net loss by the weighted-average number of common shares outstanding during the period. The Company computes diluted loss per share by dividing net loss by the sum of the weighted-average number of common shares outstanding and the weighted-average dilutive common share equivalents outstanding. The computation of diluted loss per share does not assume exercise or conversion of securities that would have an anti-dilutive effect. As of December 31, 2021, and 2020, the following items were excluded from the computation of diluted net loss per common share as their effect is anti-dilutive:

	December 31,
	2021		2020
Warrants to purchase shares		1,344,985		1,305,595
Stock options		771,788		663,016
Convertible notes		3,150,387		2,728,358
		5,267,160		4,696,969

Related Parties – The Company discloses related party transactions which are in the normal course of operations and are measured at the exchange amount.

Recent Accounting Pronouncements

Emerging Growth Company – We are an “emerging growth company” under the federal securities laws and will be subject to reduced public company reporting requirements. 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.

ProLung, Inc.

Notes to Financial Statements

Leases – In February 2016, the FASB issued ASU No. 2016-02: Leases ASU 2016-02 requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. ASU 2016-02 would be effective for the Company’s 2019 fiscal year; however, since the Company is an Emerging Growth Company and has made the election to adopt certain accounting standards when they would be applicable for private companies which is the fiscal year beginning January 1, 2022. The Company will use the modified retrospective basis. The Company entered into a three-year lease agreement in May 2019 and management is evaluating how the implementation of this standard will affect its balance sheet and statement operations.

Convertible Notes Payable – In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40),” which simplifies the accounting for convertible instruments, reduces complexity for preparers and practitioners and improves the decision usefulness and relevance of the information provided to financial statement users. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company has not yet determined the impact of adoption this standard on our financial position, results of operations or cash flows.

The Company has reviewed other recent accounting pronouncements and has determined that they will not significantly impact the Company’s results of operations or financial position.

During the year ended December 31, 2020, the Company issued $2,369,500 in convertible notes; $182,000 of which was from a current board member. These notes are unsecured, bear interest at 8% and are convertible as follows: $2,149,733 at $3.20 per share and $219,267 at $10.53 per share. If at any time prior to the maturity date, the Company completes an initial registered public offering (IPO) of its common stock, all unpaid amounts shall automatically be converted into common stock at the lower of (i) $3.20 per share and (ii) 90% of the IPO price. Interest accruing from the date of issuance to the conversion date shall be paid on the maturity date. In March 2022, these and all of the Company’s convertible notes were amended with the following new terms: (1) the maturity date was extended to September 30, 2023 and (2) there is an expanded automatic contingent conversion to include a qualified financing of at least $10M and (3) added a three month bonus interest payment in the event an automatic contingent conversion is triggered.

Since these convertible notes had a conversion price that was not “in the money” upon issuance there was no beneficial conversion feature recorded. On the date of issuance, the Company also assessed the conversion feature for possible derivative treatment (under ASC 815) and determined the conversion feature was indexed to the Company’s common stock and thus not a derivative.

Note 10 – Commitments and Contingencies

Research and Development Agreement

On July 29, 2019, the Company amended a license agreement dated April 10, 2013 between the Company and ProLung Biotech Wuxi / ProLung China (Wuxi). The original agreement allowed Wuxi to utilize the Company’s technology in China in return for royalty payments based on Wuxi’s revenues. Wuxi has yet to earn any revenue but has been conducting clinical trials. The license agreement was amended whereby Wuxi will provide the Company its clinical trial data, know-how and improvements which the Company will use outside the greater China area. This amendment further requires full collaboration (i.e., protocols and methodologies) between the two entities. In consideration for such trial data and know-how, the Company will make cash payments to Wuxi of up to $575,000 and issue up to 347,566 shares of common stock upon the completion of certain events.

Through December 31, 2021, 278,053 shares had been issued based on conditions being met. The final 69,513 shares will be issued once the final milestone is met. Through December 31, 2021, $210,000 in payments had been made plus $50,000 in equipment (see below) with the remaining $315,000 payable as follows: $290,000 currently due and $25,000 in April 2022. During the year ending December 31, 2020, the Company made $45,000 in cash payments.

COVID-19

The Company is closely monitoring the impact of the 2019 novel coronavirus, or COVID-19. COVID-19 was declared a global pandemic by the World Health Organization on March 11, 2020 and the President of the United States declared the COVID-19 outbreak a national emergency. The future impacts of the pandemic and any resulting economic impact are largely unknown and evolving. It is possible that the COVID-19 pandemic, the measures taken by the governments of countries affected and the resulting economic impact may materially and adversely affect the Company’s results of operations, cash flows and financial position, as well as its potential future customers.

Lease Agreement

In May 2019 the Company entered into a new lease agreement for its office space. The lease amount is $3,600 per month and expires in April 2022. The Company inhabited the office in September 2019 and incurred $43,200 and $43,541 in lease expense as it relates to this lease during 2021, and 2020, respectively. The remaining minimum lease expense is expected to be $14,400 for 2022.

Settlement of Liabilities

During the year ended December 31, 2021, the Company recorded $136,890 in gains from settlement of liabilities. Write-down of accounts payable related to agreed-to settlement accounted for $86,890 with the remaining $50,000 attributed to the agreed to value of equipment transferred to Wuxi. This equipment had previously been written off against inventory.

Note 11 – Income Taxes

The Company provides for income taxes using an asset and liability-based approach. Deferred income tax assets and liabilities are recorded to reflect the future tax consequences of temporary differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The Tax Cuts and Jobs Act was enacted on December 22, 2017 which reduced the U.S. corporate statutory tax rate from 35% to 21%. The Company changed its effective federal rate to 21% as the expected rate for our deferred tax items. Our effective state rate is unchanged at 5%.

The significant components of net deferred tax assets (liabilities) were as follows at December 31, 2021, and 2020:

	2021			2020
	December 31,
	2021			2020

As of December 31, 2021, the Company had no unrecognized tax benefits that, if recognized, would affect the Company’s effective income tax rate over the next 12 months. A reconciliation of the expected income tax benefit at the U.S. Federal income tax rate to the income tax benefit actually recognized for the years ended December 31, 2021, and 2020 is set forth below:

Notes to Financial Statements

As of December 31, 2020, the Company has a net operating loss carry-forward for U.S. federal income tax purposes of approximately $29.7 million. This carry-forward is available to offset future taxable income, if any, and will expire, if not used, from 2023 through 2041. The utilization of the net operating loss carry-forward is dependent upon the tax laws in effect at the time the net operating loss carry-forward can be utilized and may be limited by changes in ownership control of the Company. The Company’s U.S. federal and Utah income tax returns, constituting the returns of the major taxing jurisdictions, are subject to examination by the taxing authorities for all open years as prescribed by applicable statute. No income tax waivers have been executed that would extend the period subject to examination beyond the period prescribed by statute. The Company is no longer subject to U.S. federal tax examinations for tax years before and including December 31, 2018. The Company is no longer subject to Utah state tax examinations for tax years before and including December 31, 2016.
