Forward-Looking Statements

This press release contains forward-looking statements within the meaning of federal securities laws. These forward-looking statements are not statements of historical facts and are based on managements beliefs and assumptions and on information currently available to management. Forward-looking statements include information concerning the Companys business strategy and the design, progression and timing of its clinical trials, the ability of the single-arm UPLIFT cohort to enable registration, and expectations regarding future clinical trial results based on data achieved to date, and the sufficiency of the Companys cash on hand. Forward-looking statements generally can be identified by terms such as aims, anticipates, believes, contemplates, continues, could, designed to, efforts, estimates, expects, goal, intends, may, on track, opportunity, plans, poised for, possible, potential, predicts, projects, promises to be, seeks, should, strategy, target, will, would or similar expressions and the negatives of those terms. Forward-looking statements represent managements beliefs and assumptions only as of the date of this press release. The Companys operations involve risks and uncertainties, many of which are outside its control, and any one of which, or combination of which, could materially affect its results of operations and whether the forward-looking statements ultimately prove to be correct. Factors that may materially affect the Companys results of operations and whether these forward-looking statements prove to be correct include, among other things, that preclinical testing or early clinical results may not be predictive of the results or success of ongoing or later preclinical or clinical studies, that the identification, development and testing of the Companys product candidates and new platforms will take longer and/or cost more than planned, and that our clinical studies may not be initiated or completed on schedule, if at all, as well as those listed in the Companys Annual Report on Form 10-K filed on February 26, 2021, with the Securities and Exchange Commission (SEC), and subsequent SEC filings. In addition, while we expect that the COVID-19 pandemic might adversely affect the Companys preclinical and clinical development efforts, business operations and financial results, the extent of the impact on the Companys operations and the value of and market for the Companys common stock will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, physical distancing and business closure requirements in the U.S. and in other countries, and the effectiveness of actions taken globally to contain and treat the disease. Except as required by law, the Company assumes no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future.
