Mavacamten, sold under the brand name Camzyos, is a medication used to treat obstructive hypertrophic cardiomyopathy.[7][8]

Mavacamten is a small-molecule allosteric [9] and cardiac myosin inhibitor.[7] It was developed by MyoKardia, a subsidiary of Bristol Myers Squibb.[10] In clinical studies, mavacamten has demonstrated significant efficacy in reducing cardiac muscle contractility by targeting the sarcomere hypercontractility that is one of the characteristics of hypertrophic cardiomyopathy and inhibits excessive myosin actin cross-bridge formation, shifting the overall myosin population towards an energy-sparing, recruitable, super-relaxed state.[7]

Mavacamten was approved for medical use in the United States in April 2022.[7][11][12][13] The US Food and Drug Administration (FDA) considers it to be a first-in-class medication.[14][15]

Medical uses

Mavacamten is indicated for the treatment of adults with symptomatic New York Heart Association class II-III obstructive hypertrophic cardiomyopathy to improve functional capacity and symptoms.[7]

Adverse effects

The US prescribing information for mavacamten contains a boxed warning regarding heart failure. Mavacamten reduces LVEF and can cause heart failure due to systolic dysfunction.[7]

History

Mavacamten was granted orphan drug designation by the US Food and Drug Administration (FDA).[16]

Society and culture

Legal status

Mavacamten is approved for use in the US,[20] Canada,[21] Australia,[22] South Korea,[23] Singapore,[24] Switzerland,[25] Brazil[26] and Macau.[27]
