Overview
Brief Summary

Eligibility Criteria
Inclusion Criteria
- •Male or nonpregnant female, age ≥18 years to \<85 years.
- •Body mass index (BMI) ≥18 to \<35 kg/m2; weight ≥50 kg at Screening (BMI ≥ 18 to \< 40 kg/m2 is permitted for participants \< 50 years).
- •Diagnosed with hypertrophic cardiomyopathy at the time of Screening consistent with current American College of Cardiology Foundation/American Heart Association Guidelines.
- •LVOT peak gradient ≥ 50 mmHg measured at rest or during the Valsalva maneuver as determined by echocardiography at Screening (Part A, B and D oHCM only).
- •LVOT peak gradient \< 30 mmHg measured at rest and \< 50 mmHg measured during the Valsalva maneuver as determined by echocardiography at Screening (Part C and D nHCM only).
- •Documented left ventricular ejection fraction (LVEF) ≥ 0.60 at Screening.
- •New York Heart Association (NYHA) Classification II-III at Screening.
- •Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (KCCQ-CSS) \< 85 at Screening.
- •NT-proBNP ≥ 300 pg/mL (NT-proBNP ≥ 225 pg/mL is permitted for African American participants) (Part C and D nHCM only).
Exclusion Criteria
- •Invasive septal reduction therapy \< 180 days prior to or during Screening.
- •Documented history of active or untreated obstructive coronary artery disease during Screening or treated for obstructive coronary artery disease \< 180 days prior to Screening.
- •Documented history of myocardial infarction with residual wall motion abnormalities \< 180 days prior to or during Screening.
- •Significant valvular heart disease (moderate or greater aortic stenosis or regurgitation, moderate or greater mitral stenosis or regurgitation not due to systolic anterior motion of the mitral valve)
- •History of LV systolic dysfunction (LVEF \< 0.45) or stress cardiomyopathy at any time.
- •Known or suspected infiltrative or storage disorder causing cardiac hypertrophy that may mimic HCM, such as Fabry disease, amyloidosis, or Noonan syndrome with LV hypertrophy.
- •A history of unexplained syncope \<180 days prior to or during Screening.
- •A history of sustained ventricular tachyarrhythmia or sudden cardiac arrest \< 180 days prior or during Screening.
- •A history of known appropriate implantable cardioverter defibrillator (ICD) discharge \<180 days prior to or during Screening or ICD implanted \< 14 days prior to Screening.
- •History of permanent AF or atrial flutter. Documented AF or atrial flutter requiring rhythm restoring treatment \< 180 days prior to Screening Visit (participants with documented AF or atrial flutter requiring rhythm restoring treatment ≥ 180 days prior to Screening require adequate anticoagulation.)
