Cytokinetics Investors Face Nov. 17 Deadline To Seek Lead Plaintiff in Aficamten Securities Case

The lawsuit claims the company concealed submitting aficamten’s NDA without a REMS, resulting in a longer FDA review timeline.

Overview

  • A federal securities class action covers purchasers of Cytokinetics common stock from December 27, 2023 through May 6, 2025.
  • Investor-rights firms Faruqi & Faruqi, Glancy Prongay & Murray, and the Rosen Law Firm issued new notices urging filings for lead-plaintiff status by November 17, 2025.
  • The complaint alleges executives promoted a September 26, 2025 PDUFA date and projected second-half 2025 approval without disclosing REMS-related risk.
  • Plaintiffs cite a May 6, 2025 call stating the NDA was filed without a REMS despite pre-NDA FDA safety discussions, with a later REMS submission alleged to have added roughly three months.
  • No class has been certified, and investors may choose to join the case, seek counsel, or remain absent as the litigation continues in federal court.
