The data presented today are clinically meaningful and have demonstrated the potential to impact parameters leading to SRT eligibility.. By suppressing -cardiac myosin ATPase activity, mavacamten decreases cardiac contractility and thus exerts therapeutic . Scheduled for review in early 2022. 2022.
Mavacamten Demonstrated Significant Reduction in Need for Septal Mavacamten is a first-in-class, investigational cardiac myosin inhibitor being developed by Bristol Myers Squibb, Study met all primary and secondary endpoints and patients receiving mavacamten demonstrated improvement in key cardiac measures after 16 weeks of treatment, VALOR-HCM study presented as late-breaking clinical trial at the American College of Cardiologys 71st Annual Scientific Session. Nat Rev Cardiol. The VALOR-HCM trial recently showed that mavacamten significantly reduced the proportion of patients who were eligible for, or choose to receive, septal reduction therapy (SRT) at 16 weeks in patients . These data were presented today as a late-breaking clinical trial at the American College of Cardiologys 71st Annual Scientific Session. If approved, mavacamten would be the first cardiac myosin inhibitor for the treatment of obstructive hypertrophic cardiomyopathy Application based on positive results from Phase 3 EXPLORER-HCM trial Bristol Myers Squibb (NYSE: BMY) today announced that the European Medicines Agency (EMA) has validated its Marketing Authorization Application (MAA) for mavacamten, an investigational, first-in . A first-generation cardiac myosin inhibitor, mavacamten had already flexed its hemodynamic and clinical benefits for obstructive HCM in the phase III EXPLORER-HCM trial reported in 2020. Patients who experience a serious intercurrent illness (e.g., serious infection) or arrhythmia (e.g., atrial fibrillation or other uncontrolled tachyarrhythmia) are at greater risk of developing systolic dysfunction and heart failure. No dosage adjustment is required in patients with mild (Child-Pugh class A) to moderate (Child-Pugh class B) hepatic impairment.

Mavacamten is a small molecule, selective allosteric inhibitor of cardiac myosin ATPase developed to specifically target the underlying pathophysiology of hypertrophic cardiomyopathy by reducing actin-myosin cross-bridge formation, thereby reducing . Although the primary mechanism of mavacamten-mediated inhibition of cardiac myosin is the decrease of phosphate release from -cardiac myosin-S1, a secondary mechanism decreases the number of actin-binding heads transitioning from the weakly to the strongly bound state, which occurs before phosphate release and may provide an additional method to modulate myosin function. - Eur Heart J.

Mavacamten is in a class of medications called cardiac myosin inhibitors. Mavacamten exposure (AUC) increased up to 220% in patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment compared to patients with normal hepatic function. In clinical and preclinical studies, mavacamten has consistently reduced biomarkers of cardiac wall stress, lessened excessive cardiac contractility, increased diastolic compliance and lessened left ventricular outflow tract (LVOT) gradients.
