Real-World Registry Study of Mavacamten and Other Treatments for Symptomatic Obstructive Hypertrophic Cardiomyopathy in the US and Europe

What this Trial Is About

Researchers are studying real-world patient characteristics, treatment patterns, and both short- and long-term outcomes in people with symptomatic obstructive hypertrophic cardiomyopathy HCM across the United States and Europe. The study focuses on patients receiving mavacamten, other treatments for obstructive HCM, or no treatment due to intolerance or prior treatment failure. The U.S. portion evaluates the safety of mavacamten in this setting, while the European part assesses both its effectiveness and safety. Participants receive treatments as part of standard care, either mavacamten or other medications such as beta-blockers, non-dihydropyridine calcium channel blockers, or disopyramide. Treatments are prescribed by physicians according to routine clinical management. The study observes outcomes over time without altering prescribed care. During the study, participants are monitored for changes in heart function, symptoms, and adverse events through clinical assessments including echocardiography and patient-reported questionnaires. Researchers evaluate heart failure events, heart function measures like left ventricular outflow tract gradient and ejection fraction, arrhythmias, hospitalizations, mortality, and quality of life scores. Data is collected at baseline and followed for up to five years to understand real-world treatment effects and safety.
