SOUTH SAN FRANCISCO, Calif., Dec. 23, 2024 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that the European Medicines Agency (EMA) has validated the Marketing Authorization Application (MAA) for aficamten, a next-in-class cardiac myosin inhibitor, for the treatment of obstructive hypertrophic cardiomyopathy (HCM). The MAA will now be reviewed by the Committee for Medicinal Products for Human Use (CHMP).

“With regulatory filings for aficamten already under review in both the U.S. and China, the validation of the MAA marks an important milestone in bringing this potential medicine to even more patients with HCM worldwide,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “We look forward to working with EMA in connection with their review of our application.”

The MAA is supported by the 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 HCM, which were published in the New England Journal of Medicine.1

The MAA validation follows the acceptance by the U.S. Food and Drug Administration (FDA) of the New Drug Application (NDA) for aficamten for the treatment of obstructive HCM. The FDA assigned the NDA a standard review with a Prescription Drug User Fee Act (PDUFA) target action date of September 26, 2025.

About SEQUOIA-HCM

SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM) was the pivotal Phase 3 clinical trial of aficamten in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM).

The results from SEQUOIA-HCM showed that treatment with aficamten for 24 weeks significantly improved exercise capacity compared to placebo, increasing peak oxygen uptake (pVO2) measured by cardiopulmonary exercise testing (CPET) by 1.8 ml/kg/min compared to baseline in patients treated with aficamten versus 0.0 ml/kg/min in patients treated with placebo (least square mean (LSM) difference [95% CI] of 1.74 mL/kg/min [1.04 - 2.44]; p=0.000002). Statistically significant improvements were observed in all 10 prespecified secondary endpoints, including Valsalva left ventricular outflow tract (LVOT) gradient, New York Heart Association (NYHA) Functional Class, Kansas City Cardiomyopathy Clinical Summary Score (KCCQ-CSS), and proportion with LVOT gradient
