SOUTH SAN FRANCISCO, May 20, 2023 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that additional data from Cohort 4 of REDWOOD-HCM (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM), a Phase 2, open-label clinical trial of aficamten in patients with non-obstructive hypertrophic cardiomyopathy (nHCM), were presented in a Late Breaking Clinical Trial session at Heart Failure 2023 an International Congress of the European Society of Cardiology taking place online and in Prague, Czech Republic from May 20, 2023 – May 23, 2023.

“We’re pleased to see that, in addition to the previously reported improvements in both functional class and cardiac biomarkers, patients with nHCM treated with aficamten in Cohort 4 of REDWOOD-HCM experienced a statistically significant improvement in patient reported health status, the KCCQ clinical summary score, an important measure of disease burden,” said Fady I. Malik, M.D., Ph.D., Cytokinetics’ Executive Vice President of Research & Development. “Additionally, this study reported for the first time that patients who suffered from angina, a common and debilitating complaint in patients with nHCM that is a consequence of hypertrophy in the heart, reported a significant reduction in the frequency of anginal symptoms. We look forward to advancing aficamten into a Phase 3 clinical trial in patients with nHCM which is expected to begin in the second half of this year.”

The new data from Cohort 4, presented today by Ahmad Masri, M.D. M.S., Director of the Hypertrophic Cardiomyopathy Center at Oregon Health & Science University, build on the previously presented initial data from Cohort 4 in REDWOOD-HCM, including analyses of all 41 patients through the end of the 12-week clinical study, and new data relating to the effect of aficamten on Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Symptom Score (CSS) and angina.
