Study Summary

The purpose of this study is to compare the efficacy and safety of aficamten (CK-3773274) compared with metoprolol succinate in adults with symptomatic hypertrophic cardiomyopathy and left ventricular outflow tract obstruction

Primary Outcome

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.

Interventions

  • DRUG Placebo to match aficamten
  • DRUG Aficamten (CK-3773274) (5 mg, 10 mg, 15 mg and 20 mg)
  • DRUG Metoprolol succinate (50 mg, 100 mg, 150 mg and 200 mg)
  • DRUG Placebo to match metoprolol succinate
