Summary

This trial tests how a new drug affects the heart's structure in adults with a heart condition called oHCM.

Who is the study for?
This trial is for adults with symptomatic obstructive hypertrophic cardiomyopathy (oHCM), specifically those who experience certain levels of heart blockage and have a normal or near-normal heart pumping function. They should be somewhat limited in their physical activity but not bedridden. People with recent severe cardiac events, pacemakers, conditions that look like oHCM, or major artery blockages can't join.
What is being tested?
The study tests the effects of Mavacamten on the heart's structure using advanced imaging techniques in people with oHCM. Participants will either receive Mavacamten or a placebo to compare outcomes between the two groups.
What are the potential side effects?
While specific side effects for this trial are not listed, common side effects of drugs like Mavacamten may include dizziness, changes in blood pressure and heartbeat, fatigue, and potential impact on liver enzymes.
