SOUTH SAN FRANCISCO, Calif., May 13, 2024 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that additional results from SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM), the pivotal Phase 3 clinical trial of aficamten in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM), elaborating on dosing and safety data as well as the effect of aficamten on exercise performance were presented at Heart Failure 2024, an International Congress of the European Society of Cardiology. The primary results from SEQUOIA-HCM were also presented in the same Late Breaking Clinical Trial session at the Congress and simultaneously published in the New England Journal of Medicine.1

“These additional analyses from SEQUOIA-HCM further illuminate the positive impact of treatment with aficamten on measures of dosing, safety, efficacy and impact on quality of life beyond the primary and secondary endpoints of the trial,” said Stuart Kupfer, M.D., SVP, Chief Medical Officer. “Notably, the dosing and safety data support dose down-titration in cases of low left ventricular ejection fraction (LVEF), potentially enabling ease of individualized dosing for patients treated with aficamten and also may inform a tailored risk mitigation approach.”
