Takeaway

Phase 3 efficacy readout for CAMZYOS in non-obstructive HCM. CAMZYOS is currently approved only in the obstructive form (oHCM); non-obstructive HCM has roughly 2x the U.S. patient population. Watch: KCCQ-23 score and pVO2 change vs. placebo.

CAMZYOS
mavacamten · INN
MoAcardiac myosin inhibitor

CAMZYOS (mavacamten) is a first-in-class oral cardiac myosin inhibitor developed by Bristol Myers Squibb that treats hypertrophic cardiomyopathy (HCM) — a genetic condition in which the heart muscle thickens abnormally and obstructs blood flow. The drug reduces the number of myosin-actin cross-bridges that form during each heartbeat, decreasing the force of contraction and relieving the outflow obstruction that causes breathlessness, chest pain, and syncope. CAMZYOS is approved for symptomatic obstructive HCM and is being studied in non-obstructive HCM — a distinct phenotype with twice the patient population and no approved drug therapy — in an ongoing Phase 3 trial.
