Specifically, defendants represented that Cytokinetics expected approval from the U.S. Food and Drug Administration (“FDA”) for its NDA for aficamten in the second half of 2025, based on a September 26, 2025 Prescription Drug User Fee Act (“PDUFA”) date, and failed to disclose material risks related to Cytokinetics’ failure to submit a Risk Evaluation and Mitigation Strategy (“REMS”) that could delay the regulatory process. When the true details entered the market, the lawsuit claims that investors suffered damages.
