SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, or this Report, contains forward-looking statements that involve risks, uncertainties, and assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. The statements contained in this Report that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of those terms, and similar expressions that convey uncertainty of future events or outcomes. Any statements contained herein that are not statements of historical facts may be deemed to be forward-looking statements. Forward-looking statements in this Report include, but are not limited to, statements about:

•Our estimates regarding expenses, future revenue, capital requirements and needs for additional financing;

•The success, cost and timing of our product development activities and preclinical and clinical trials of our product candidates;

•Our plans to initiate, recruit and enroll patients in, and conduct our clinical trials at the pace that we project;

•Our plans and strategy to obtain and maintain regulatory approvals of our product candidates;

•Our plans and strategy to obtain funding for our operations, including funding necessary to complete further development and, upon successful development, if approved, commercialize any of our product candidates;

•The effect and impact of new, existing and proposed laws and regulations;

•The potential benefit of orphan drug and Fast Track designations for any of our product candidates;

•Our ability to compete with companies currently marketing or engaged in the development of integrin-based therapeutics;

•Our plans and strategy regarding obtaining and maintaining intellectual property protection for our product candidates and the duration of such protection;

•Our plans and strategy regarding the manufacture of our product candidates for clinical trials and for commercial use, if approved;

•Our ability to enter into successful new collaborations;

•Our dependence on future collaborators for developing, obtaining regulatory approval for and commercializing product candidates in the collaboration;

•Our receipt and timing of any milestone payments or royalties under any future research collaboration or license agreements or arrangements;

•Our plans and strategy regarding the commercialization of any products that are approved for marketing and our ability to establish adequate pricing in the U.S. and international markets;

•The size and growth potential of the markets for our product candidates, and our ability to serve those markets, either alone or in combination with others;

•Our ability to attract and retain qualified employees and key personnel;

•Our expectations regarding government and third-party payor coverage and reimbursement; and

•Our expectations of obtaining a positive health technology assessment recommending our products.

These statements are based on the beliefs and assumptions of our management, which are in turn based on information currently available to management. Such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results and timing expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section entitled “Risk Factors” included under Part II, Item 1A in this Report. Furthermore, such forward-looking statements speak only as of the date of this Report. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

SUMMARY OF RISKS ASSOCIATED WITH OUR BUSINESS

Our business involves significant risks, some of which are summarized below. The summary risk factors listed below should be read together with the text of the full risk factors discussed in "Part II, Item 1A - Risk Factors" in this Report. You should carefully consider the risks described below, as well as the other information in this Report, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as well as in other documents that we file with the Securities and Exchange Commission, or the SEC. The occurrence of any of the events or developments described in this Report could have a material adverse effect on our business, financial condition, results of operations, growth prospects and stock price. In such an event, the market price of our common stock could decline. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations and the market price of our common stock.

Risks Related to Our Financial Position, Need for Additional Capital and Operations

•We have incurred significant net losses since inception, and we expect to continue to incur significant net losses for the foreseeable future.

•We will require substantial additional capital to finance our operations. If we are unable to raise such capital when needed, or on acceptable terms, we may be forced to delay, reduce and/or eliminate one or more of our research and drug development programs, future commercialization efforts or other operations.

Risks Related to Research and Development and the Biopharmaceutical Industry

•We have a limited operating history, which may make it difficult to evaluate our prospects and likelihood of success.

•Our business is highly dependent on the success of our product candidates that we advance into the clinic. All of our product candidates will require significant additional development before we may be able to seek regulatory approval for and launch a product commercially.

•Clinical development involves a lengthy, complex, and expensive process, with an uncertain outcome to support either a marketing authorization or positive pricing and reimbursement decisions.

•We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

•We may fail to obtain and maintain certain regulatory exclusivities and orphan designations in some jurisdictions and therefore fail to secure orphan exclusivity or other exclusivity extensions in those jurisdictions.

•Our ongoing and future clinical trials may reveal significant adverse events or unexpected drug-drug interactions not seen in our preclinical studies and may result in a safety profile that could delay or prevent regulatory approval or market acceptance of any of our product candidates.

•If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

•We face substantial competition, which may result in others discovering, developing, or commercializing products before or more successfully than us.

•We may fail to secure an appropriate reimbursement price or a positive health technology assessment.

Risks Related to Our Intellectual Property

•Our success depends in part on our ability to obtain patent term extensions and to protect our intellectual property. It is difficult and costly to protect our proprietary rights and technology, and we may not be able to ensure their protection.

•Our future collaborators may assert ownership or commercial rights to inventions they develop from research we support, or that we develop from our use of the tissue samples or other biological materials which they provide to us, or otherwise arising from such collaboration.

Risks Related to Our Reliance on Third Parties

•We rely on third parties to conduct certain aspects of our preclinical studies and clinical trials and for tissue samples and other materials required for our research and development activities.

•We rely on single-source third party suppliers located in foreign jurisdictions, including China, to manufacture our drug candidates. An interruption in this supply, caused by a business interruption or geopolitical events, could materially disrupt our research and development activities.

•If we are unable to enter into new collaborations, or if these collaborations are not successful, our business could be adversely affected.

Risks Related to Managing Our Business and Operations

•Our loss of key management personnel, or our failure to recruit additional highly skilled personnel, will impair our ability to develop current product candidates or identify and develop new product candidates, could result in loss of markets or market share and could make us less competitive.
