Cytokinetics disclaims any intent or obligation to update these forward-looking statements and claims the protection of the Act's Safe Harbor for forward-looking statements. Examples of such statements include, but are not limited to, statements express or implied related Cytokinetics’ research and development and commercial readiness activities, including the initiation, conduct, design, enrollment, progress, continuation, completion, timing and results of clinical trials, projections regarding growing prevalence, low survival rates and market opportunity in heart failure, hypertrophic cardiomyopathy (HCM) or amyotrophic lateral sclerosis (ALS); projections regarding the size of the addressable patient population for omecamtiv mecarbil, aficamten or reldesemtiv; Cytokinetics’ commercial readiness for omecamtiv mecarbil; the likelihood and/or timing of regulatory approval for our new drug application for omecamtiv mecarbil or any future new drug application for any of our other drug candidates; the timing of a second interim analysis of COURAGE-ALS, the timing of commencement of a second phase 3 clinical trial of aficamten as a monotherapy in patients with obstructive HCM, the timing of commencement of a phase 3 clinical trial of aficamten in nonobstructive HCM, our ability to fully enroll or to announce the results of any of our clinical trials by any particular date; Cytokinetics’ cash expenditures or runway; the results of any of our interactions with the FDA or any other regulatory authority regarding omecamtiv mecarbil or any of our other drug candidates; the properties, potential benefits and commercial potential of aficamten, omecamtiv mecarbil, reldesemtiv and Cytokinetics’ other drug candidates. Such statements are based on management's current expectations; but actual results may differ materially due to various risks and uncertainties, including, but not limited to, potential difficulties or delays in the development, testing, regulatory approvals for trial commencement, progression or product sale or manufacturing, or production of Cytokinetics’ drug candidates that could slow or prevent clinical development or product approval, including risks that current and past results of clinical trials or preclinical studies may not be indicative of future clinical trial results, patient enrollment for or conduct of clinical trials may be difficult or delayed, Cytokinetics’ drug candidates may have adverse side effects or inadequate therapeutic efficacy, the FDA or foreign regulatory agencies may delay or limit Cytokinetics’ ability to conduct clinical trials, and Cytokinetics may be unable to obtain or maintain patent or trade secret protection for its intellectual property; Cytokinetics may incur unanticipated research, development and other costs or be unable to obtain financing necessary to conduct development of its products; standards of care may change, rendering Cytokinetics’ drug candidates obsolete; and competitive products or alternative therapies may be developed by others for the treatment of indications Cytokinetics’ drug candidates and potential drug candidates may target. These forward-looking statements speak only as of the date they are made, and Cytokinetics undertakes no obligation to subsequently update any such statement, except as required by law.
