入选标准

  • - Males and females between 18 and 85 years of age, inclusive, at screening.
  • - Body mass index <35 kg/m^2.
  • - Diagnosed with HCM per the following criteria:
  • a. Has LV hypertrophy and non-dilated LV chamber in the absence of other cardiac disease and
  • b. Has an end-diastolic LV wall thickness as measured by the echocardiography core laboratory of:
  • =15 mm in one or more myocardial segments OR
  • =13 mm in one or more wall segments and a known-disease-causing gene mutation or positive family history of HCM
  • - Has resting LVOT-G =30 mmHg and post-Valsalva LVOT-G =50 mmHg during screening as determined by the echocardiography core laboratory
  • - LVEF =60% at screening as determined by the echocardiography core laboratory.
  • - New York Heart Association (NYHA) Functional Class II or III at screening
  • - Hemoglobin =10 g/dL at screening.
  • - Respiratory exchange ratio (RER) =1.05 and pVO2 =90% predicted on the screening CPET per the core laboratory.
  • - Patients on beta-blockers, verapamil, diltiazem, or disopyramide should have been on a stable doses for >6 weeks prior to randomization and anticipate remaining on the same medication regimen during the trial. Patients treated with disopyramide must also be concomitantly treated with a beta blocker and/or calcium channel blocker.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 169
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 113

排除标准

  • - Known or suspected infiltrative, genetic or storage disorder causing cardiac hypertrophy that mimics oHCM (eg, Noonan syndrome, Fabry disease, amyloidosis).
  • - Significant valvular heart disease (per investigator judgment).
  • a) Moderate-severe valvular aortic stenosis.
  • b) Moderate-severe mitral regurgitation not due to systolic anterior motion of the mitral valve.
  • - History of LV systolic dysfunction (LVEF <45%) or stress cardiomyopathy at any time during their clinical course.
  • - Inability to exercise on a treadmill or bicycle (eg, orthopedic limitations).
  • - Has been treated with septal reduction therapy (surgical myectomy or percutaneous alcohol septal ablation) or has plans for either treatment during the trial period.
  • - Documented paroxysmal atrial fibrillation during the screening period.
  • - Paroxysmal or permanent atrial fibrillation is only excluded IF:
  • rhythm restoring treatment (eg, direct-current cardioversion, atrial fibrillation ablation procedure, or antiarrhythmic therapy)has been required =6 months prior to screening.
  • rate control and anticoagulation have not been achieved for at least 6 months prior to screening.
  • - History of syncope or sustained ventricular tachyarrhythmia with exercise within 6 months prior to screening.
  • - Has received prior treatment with CK-3773274 or mavacamten.
  • Exclusion Criteria for CMR Sub-study
  • - Inability to tolerate CMR.
  • - Has an implantable cardioverter-defibrillator (ICD).
  • - Has a cardiac pacemaker.
