Trial Outcomes & Findings for Phase 3 Trial to Evaluate the Efficacy and Safety of Aficamten Compared to Metoprolol Succinate in Adults With Symptomatic oHCM (NCT NCT05767346)

NCT ID: NCT05767346

Last Updated: 2026-06-09

Results Overview

Effect of aficamten compared with metoprolol succinate on exercise capacity in patients with symptomatic obstructive hypertrophic cardiomyopathy (oHCM). Exercise capacity was determined through changes in peak oxygen uptake (pVO2) after 24 weeks of treatment. pVO2 was measured by cardiopulmonary exercise testing (CPET) on a treadmill or bicycle. A higher pVO2 indicates better cardiorespiratory fitness.

Effect of aficamten compared with metoprolol succinate on participant health status was measured by change in KCCQ-CSS. The KCCQ is a patient-reported outcome designed to assess the physical limitations, symptoms, self-efficacy, quality of life, and social limitation of patients with heart failure symptoms. The CSS is the sum of the physical limitation score and the total symptom score. The KCCQ-Clinical Symptoms Score (KCCQ-CSS) is scored on a scale from 0 to 100, with higher scores indicating better physical functioning and symptoms.
