Trial Outcomes

Change From Baseline to Week 16 in Cardiac Troponin

A geometric mean ratio was used to assess the change from baseline to week 16 in cardiac troponin. Baseline values are defined as the last non-missing value prior to the first dose of study drug unless specified otherwise. (NCT04349072)
Timeframe: Baseline and week 16

Interventionng/L (Geometric Mean)
Mavacamten0.50
Placebo to Mavacamten1.03

Change From Baseline to Week 16 in Kansas City Cardiomyopathy Questionnaire 23-item Version, Clinical Summary Score (KCCQ-23, CSS)

The KCCQ-23 is a 23-item, self-administered questionnaire that measures the impact of a participant's cardiovascular disease or its treatment on 6 distinct domains using a 2-week recall period: symptoms/signs, physical limitation, quality of life (QoL), social limitations, self-efficacy, and symptom stability. The KCCQ 23 Clinical Summary Score (CSS) is derived from the Total Symptom Score (TSS) and the Physical Limitations (PL) score of the KCCQ 23. The CSS, TSS, and the PL score range from 0 to 100 with higher scores representing less severe symptoms and/or physical limitations. The CSS is a mean of the TSS and the PL score. (NCT04349072)

Change From Baseline to Week 16 in N-Terminal Pro-b-Type Natriuretic Peptide (NT-proBNP)

A geometric mean ratio was used to assess the change from baseline to Week 16 in N-Terminal Pro-b-Type Natriuretic Peptide (NT-proBNP). Baseline values are defined as the last non-missing value prior to the first dose of study drug unless specified otherwise. (NCT04349072)

Change From Baseline to Week 16 in Post-Exercise Left Ventricular Outflow Tract (LVOT) Gradient

Change from baseline to week 16 in post-exercise left ventricular outflow tract (LVOT) gradient. Baseline values are defined as the last non-missing value prior to the first dose of study drug unless specified otherwise. (NCT04349072)
Timeframe: Baseline and week 16

Composite of Decision to Proceed With Septal Reduction Therapy (SRT) and SRT Guideline Eligible at Week 16

"Participants who decided to proceed with SRT or were eligible for SRT at week 16. Participants with missing assessments were classified as meeting the primary endpoint (did not improve).~SRT eligibility using the New York Heart Association Functional Class (NYHA) and left ventricular outflow tract (LVOT) assessments per the 2011 ACCF/AHA guideline clinical and hemodynamic criterion are below:~NYHA Class III or IV/ NYHA Class II with exertion-induced syncope/near syncope, AND~Dynamic LVOT gradient at rest or with provocation >= 50 mmHg.~NYHA Class II at week 16, the following rules will be applied:~NYHA Class II with history of exertional syncope/ syncope at baseline and at W16 is still NYHA Class II, they remain SRT eligible IF their maximal LVOT gradient is ≥ 50mmHg~NYHA Class III/IV at baseline and at W16 has improved to Class II, they are no longer SRT eligible UNLESS they have AE of exertional syncope or pre-syncope during the 16 weeks."

Timeframe: Week 16

Number of Participants With at Least One Class Improvement From Baseline in New York Heart Association (NYHA) Class at Week 16

"The NYHA functional classification of heart failure assigns participants to 1 of 4 categories based on the participants symptoms. Baseline values are defined generally as the last available value before the first administration of study drug of analysis interest. Participants with missing NYHA class assessments are treated as no improvement.~Class 1: No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath).~Class 2: Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath).~Class 3: Marked limitation of physical activity. Comfortable at rest. Less-than ordinary-activity causes fatigue, palpitation, or dyspnea. Class 4: Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases." (NCT04349072)
