Who can take part
You may be able to join if
- Between 18–85 years of age at screening
- Body mass index < 40 kg/m2
- Diagnosed with nHCM and has a screening echocardiogram with the following: • End-diastolic LV wall thickness: − ≥ 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 AND − Resting LVOT-G < 30 mmHg AND Valsalva LVOT-G < 50 mmHg AND − LVEF ≥ 60% • Participants with a history of intracavitary obstruction are eligible
- New York Heart Association (NYHA) class II or III
- Respiratory exchange ratio of ≥ 1.00 at screening by CPET and predicted peak oxygen uptake (pVO2) of ≤ 90% for age and sex
- KCCQ-CSS score ≤ 85
You likely can't join if
- Significant valvular heart disease (per Investigator judgment) • Moderate or severe valvular aortic stenosis or fixed subaortic obstruction • Moderate or severe mitral regurgitation
- History of resistant hypertension (persistently elevated blood pressure despite maximal doses of 3 or more classes of medications for hypertension control)
- Screening diastolic blood pressure ≥ 100 mmHg
- Undergone septal reduction therapy < 6 months prior to screening
- Is being considered for or is likely to be considered for heart transplant listing or left ventricular assist device placement during the study period
- Paroxysmal or permanent atrial fibrillation is excluded only if: • rhythm restoring treatment (e.g., direct-current cardioversion, atrial fibrillation ablation procedure, or antiarrhythmic therapy) has been required ≤ 3 months prior to randomization • rate control and anticoagulation have not been achieved for at least 3 months prior to screening
