Primary Outcome Measures :
- Incidence of adverse events observed during dosing of CK-3773274 in patients with oHCM [ Time Frame: 14 weeks ]Patient incidence of reported adverse events (AEs)
Secondary Outcome Measures :
- Incidence of left ventricular ejection fraction (LVEF) < 50% observed during dosing of during dosing of CK-3773274 in patients with oHCM [ Time Frame: 14 weeks ]Patient incidence of left ventricular ejection fraction (LVEF) < 50%
- Incidence of serious adverse events observed during dosing of CK-3773274 in patients with oHCM [ Time Frame: 14 weeks ]Patient incidence of reported serious adverse events (SAEs)
- Concentration-response relationship of CK-3773274 on the resting left ventricular outflow tract gradient (LVOT-G) on echocardiogram over 10 weeks of treatment [ Time Frame: 10 weeks ]Slope of the relationship of the plasma concentration of CK-3773274 to the change from baseline in the resting LVOT-G
- Concentration-response relationship of CK-3773274 on the post-Valsalva left ventricular outflow tract gradient (LVOT-G) on echocardiogram over 10 weeks of treatment [ Time Frame: 10 weeks ]Slope of the relationship of the plasma concentration of CK-3773274 to the change from baseline in the post-Valsalva LVOT-G
- Dose response relationship of CK-3773274 in patients with oHCM at baseline [ Time Frame: 10 weeks ]Change from baseline in resting LVOT-G over time as a function of dose
- Dose response relationship of CK-3773274 in patients with oHCM post-Valsalva [ Time Frame: 10 weeks ]Change from baseline in post-Valsalva LVOT-G to Week 10
- Plasma concentrations of CK-3773274 in patients with oHCM [ Time Frame: Day 1 to End of Study (EOS) (Week 14) ]Observed maximum plasma concentration (Cmax) and trough plasma concentration (Ctrough) for CK 3773274 during dosing

| Ages Eligible for Study: | 18 Years to 85 Years (Adult, Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria
- Males and females between 18 and 85 years of age at screening.
- Body weight is ≥45 kg at screening.
-
Diagnosed with oHCM per the following criteria:
- Has left ventricular (LV) hypertrophy with non-dilated LV chamber in the absence of other cardiac disease.
- Has minimal wall thickness ≥15 mm (minimal wall thickness ≥13 mm is acceptable with a positive family history of HCM or with a known disease-causing gene mutation).
- Adequate acoustic windows for echocardiography.
-
Has LVOT-G during screening as follows:
- Resting gradient ≥50 mmHg OR
- Resting gradient ≥30 mmHg and <50 mmHg with post-Valsalva LVOT-G ≥50 mmHg
- LVEF ≥60% at screening.
- New York Heart Association (NYHA) Class II or III at screening.
- Patients on beta-blockers, verapamil, diltiazem, or ranolazine should have been on stable doses for >4 weeks prior to randomization and anticipate remaining on the same medication regimen during the study.
Exclusion Criteria
- Aortic stenosis or fixed subaortic obstruction.
- Known infiltrative or storage disorder causing cardiac hypertrophy that mimics oHCM (eg, Noonan syndrome, Fabry disease, amyloidosis).
- History of LV systolic dysfunction (LVEF <45%) at any time during their clinical course.
- Documented history of current obstructive coronary artery disease (>70% stenosis in one or more epicardial coronary arteries) or documented history of myocardial infarction.
- Has been treated with septal reduction therapy (surgical myectomy or percutaneous alcohol septal ablation) or has plans for either treatment during the study period.
- Has been treated with disopyramide or antiarrhythmic drugs that have negative inotropic activity within 4 weeks prior to screening.
- Paroxysmal atrial fibrillation or flutter documented during the screening period.
- Paroxysmal or permanent atrial fibrillation requiring rhythm restoring treatment (eg, direct-current cardioversion, ablation procedure, or antiarrhythmic therapy) ≤6 months prior to screening. (This exclusion does not apply if atrial fibrillation has been treated with anticoagulation and adequately rate-controlled for >6 months).
- History of syncope or sustained ventricular tachyarrhythmia with exercise within 6 months prior to screening.
- Has received prior treatment with CK-3773274 or is currently receiving mavacamten.
