First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This phase 4 study tests the drug mavacamten in 63 adults with a type of heart muscle disease called obstructive hypertrophic cardiomyopathy. The goal is to see if the drug can improve heart structure, measured by MRI, and ease symptoms like shortness of breath. Participants take mavacamten for 48 weeks, and researchers track changes in heart chamber size and muscle thickness.

What this could lead to

If successful, this could show that mavacamten improves heart structure and function, potentially leading to better symptom control and quality of life for people with this condition.
