内容記述
内容記述 <p>Background: Mavacamten, a cardiac myosin inhibitor, significantly improved symptoms and cardiac function vs. placebo in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM) in EXPLORER-HCM. However, the efficacy and safety profiles of mavacamten in Japanese patients are unclear. Methods and Results: HORIZON-HCM is a Phase 3 single-arm study in Japanese patients with symptomatic obstructive HCM. The mavacamten starting dose was 2.5 mg; individualized dose titration occurred in Weeks 6–20 based on Valsalva left ventricular outflow tract (LVOT) gradient and resting left ventricular ejection fraction (LVEF). Overall, 38 patients were treated; 36 completed the 30-week primary treatment analysis period. Clinically significant improvements in postexercise LVOT gradient were observed after 30 weeks of treatment (mean change from baseline −60.7 mmHg). Improvements in N-terminal pro B-type natriuretic peptide, New York Heart Association class, and Kansas City Cardiomyopathy Questionnaire-23 Clinical Summary Score were observed over 30 weeks, and mean LVEF was ≥74% at all visits. Treatment-emergent adverse events (TEAEs) and serious TEAEs were reported in 63.2% and 7.9% of patients, respectively; none resulted in treatment discontinuation. One patient experienced a transient asymptomatic reduction in LVEF to &lt;50%. No deaths occurred during the study. Conclusions: In Japanese patients with obstructive HCM, mavacamten was associated with similar improvements in LVOT gradients, cardiac biomarkers, and symptoms to those observed in EXPLORER-HCM. Treatment was well tolerated with no new safety concerns.</p>
