The Law Offices of Frank R. Cruz is investigating potential claims against the board of directors of Cytokinetics, Incorporated (“Cytokinetics” or the “Company”) (NASDAQ: CYTK) concerning whether the board breached its fiduciary duties to shareholders.

On May 1, 2025, Cytokinetics disclosed that the FDA has extended the review period for its cardiac myosin inhibitor drug, aficamten, by three months, citing additional time required to review newly submitted Risk Evaluation and Mitigation Strategy (REMS). The Company further revealed that, “following pre-NDA discussions with FDA in which safety and risk mitigation were discussed, Cytokinetics submitted the NDA for aficamten in oHCM without an accompanying REMS.”

On this news, Cytokinetics’s stock price fell $5.57, or 12.9%, to close at $37.35 per share on May 2, 2025, thereby injuring investors.

Then, on May 6, 2025, Cytokinetics admitted that it had multiple pre-NDA meetings with the FDA discussing safety monitoring and risk mitigation but chose to submit the NDA without a REMS, relying on labeling and voluntary education materials.

On this news, Cytokinetics’s stock price fell $0.93, or 2.7%, to close at $33.04 per share on May 7, 2025, thereby injuring investors further.
