A Study to Evaluate Mavacamten in Adults With Symptomatic Obstructive HCM Who Are Eligible for Septal Reduction Therapy

This is a randomized, double-blind, placebo-controlled, multi-center study in the United States (U.S.) that will evaluate the effect of mavacamten treatment on reducing the number of septal reduction therapy (SRT) procedures performed in subjects with symptomatic obstructive hypertrophic cardiomyopathy (oHCM [also known as HOCM]) who are eligible for SRT based on ACCF/AHA 2011 and/or ESC 2014 guidelines.

Stanford is currently not accepting patients for this trial.
