Forward-Looking Statements Statements in this Presentation that are not statements of historical fact are forward-looking statements. Such forward-looking statements include, without limitation, statements regarding our research and clinical development activities, plans and projected timelines, business strategy and plans, regulatory matters, objectives of management for future operations, market size and opportunity, our ability to complete certain milestones and our expectations regarding the relative benefits of our drug candidates versus competitive therapies. Words such as “believe,” “can”, “continue,” “anticipate,” “could,” “estimate,” “plan,” “predict,” “expect,” “intend,” “will,” “may,” “goal,” “upcoming,” “near term”, “milestone”, “potential,” “target” or the negative of these terms or similar expressions are intended to identify forward-looking statements, though not all forward-looking statements necessarily contain these identifying words. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Risks that contribute to the uncertain nature of the forward-looking statements include, without limitation: our preclinical studies and clinical trials may not be successful; regulatory authorities, including the U.S. Food and Drug Administration (FDA) may not agree with our interpretation of the data from clinical trials of our drug candidates; we may decide, or regulatory authorities may require us, to conduct additional clinical trials or to modify our ongoing clinical trials; we may experience delays in the commencement, enrollment, completion or analysis of clinical testing for our drug candidates, or significant issues regarding the adequacy of our clinical trial designs or the execution of our clinical trials may arise, which could result in increased costs and delays, or limit our ability to obtain regulatory approval; our drug candidates may not receive regulatory approval or be successfully commercialized; unexpected adverse side effects or inadequate therapeutic efficacy of our drug candidates could delay or prevent regulatory approval or commercialization; the COVID-19 pandemic may disrupt our business and that of third parties on which we depend, including delaying or otherwise disrupting our research and development activities; and we may not be able to obtain additional financing. These forward-looking statements should not be taken as forecasts or promises nor should they be taken as implying any assurance or guarantee that the assumptions on which such forward-looking statements have been made are correct or exhaustive. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date this Presentation is given. Other risks and uncertainties affecting us are described more fully in our filings with the Securities and Exchange Commission. We undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made. This Presentation discusses drug candidates that are under clinical study and which have not yet been approved for marketing by the U.S. Food and Drug Administration. No representation is made as to the safety or effectiveness of these drug candidates for the use for which such drug candidates are being studied.
