Forward-Looking Statements
This presentation contains forward-looking statements within the meaning of Private Securities Litigation Reform Act of 1995 that involve substantial risks and uncertainties, including statements regarding the Company's plans, strategies and prospects for its business and statements regarding the development status of the Company's product candidates, the timing of availability of clinical trial data and the Company's ability to fund its operations until the second half of 2022. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "should," "target," "will," "would" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Any forward-looking statements are based on management's current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in, or implied by, such forward-looking statements. These risks and uncertainties include, but are not limited to, risks associated with: the Company's ability to obtain and maintain necessary approvals from the FDA and other regulatory authorities; the Company's ability to continue to advance its product candidates in clinical trials; whether preliminary or interim data from a clinical trial will be predictive of the final results of the trial; replication in later clinical trials positive results found in preclinical studies and early-stage clinical trials of CPI-0610,CPI-1205 and CPI-0209; the Company's ability to advance the development of its product candidates under the timelines it anticipates, or at all, in current and future clinical trials; the Company's ability to obtain, maintain, or protect intellectual property rights related to its product candidates; manage expenses; the Company's ability to raise the substantial additional capital needed to achieve its business objectives; the COVID-19 pandemic and general economic and market conditions; and whether the previously announced acquisition of the Company by MorphoSys AG will be consummated on a timely basis. CPI-0610,CPI-1205 and CPI-0209 are investigational therapies and have not been approved by the FDA (or any other regulatory authority). For a discussion of other risks and uncertainties, any of which could cause the Company's actual results to differ from those contained in the forward-looking statements, see the "Risk Factors" section, as well as discussions of potential risks, uncertainties, and other important factors, in the Company's most recent filings with the Securities and Exchange Commission. In addition, the forward-looking statements included in this presentation represent the Company's views as of the date hereof and should not be relied upon as representing the Company's views as of any date subsequent to the date hereof. The Company anticipates that subsequent events and developments will cause the Company's views to change. However, while the Company may elect to update these forward-looking statements at some point in the future, the Company specifically disclaims any obligation to do so.
