Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On August 7, 2009, Altus Pharmaceuticals Inc. (the "Company") received a staff deficiency letter from The NASDAQ Stock Market ("NASDAQ") notifying the Company that, based on the Company’s stockholders’ equity as reported in the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2009, the Company is not in compliance with the minimum stockholders’ equity requirement of $10 million for continued listing on The NASDAQ Global Market as set forth in NASDAQ Listing Rule 5450(b)(1)(A). As of June 30, 2009, the Company’s stockholders’ equity was approximately $5.8 million. This notification has no immediate effect on the Company’s listing on The NASDAQ Global Market or on the trading of the Company’s common stock.

As provided in the NASDAQ’s rules, the Company has until August 24, 2009 to provide NASDAQ with a plan to regain compliance with The NASDAQ Global Market continued listing requirements. If NASDAQ accepts the Company’s plan, of which there can be no assurance, NASDAQ may grant the Company up to 105 days from August 7, 2009 to achieve and sustain compliance. If NASDAQ determines that the Company’s plan is not sufficient to achieve and sustain compliance, it will provide written notice that the Company’s common stock would be subject to delisting from The NASDAQ Global Market. At such time, the Company may request a hearing before a NASDAQ Listing Qualifications Panel. In such an event, the Company’s common stock would remain listed on The NASDAQ Global Market pending a final determination by the panel. The Company may also apply to list its common stock on the NASDAQ Capital Market. The NASDAQ Capital Market is a continuous trading market that operates in the same manner as The NASDAQ Global Market. All companies whose securities are listed on The NASDAQ Capital Market must meet certain financial requirements and adhere to NASDAQ’s corporate governance standards. The Company believes that it currently meets all of the requirements for continued listing on The NASDAQ Capital Market, other than the minimum bid price of at least $1.00.

The Company is considering its options regarding the NASDAQ notice, including potentially submitting a plan to NASDAQ on or before August 24, 2009 to maintain its listing on The NASDAQ Global Market or applying to transfer the listing of its common stock to The NASDAQ Capital Market.

A copy of the Company’s press release dated August 11, 2009 reporting receipt of the deficiency letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
