CAMZYOS (mavacamten) is an oral, allosteric, and reversible cardiac myosin inhibitor designed to modulate the number of myosin heads entering power-generating states, thereby reducing excessive contractility characteristic of hypertrophic cardiomyopathy. By selectively targeting cardiac myosin, CAMZYOS decreases left ventricular outflow tract (LVOT) obstruction and improves cardiac filling pressures, addressing the underlying pathophysiology of obstructive HCM.
The pharmacological action of CAMZYOS results in a dose-dependent reduction in LVOT gradients and improvement in exercise capacity and symptoms, as demonstrated in clinical trials. Due to its potential to cause systolic dysfunction and heart failure, careful patient selection, regular echocardiographic monitoring, and adherence to the CAMZYOS REMS Program are mandatory to ensure safe administration. The safety and efficacy in populations outside the specified indication, including pediatric and pregnant patients, are not specified in the specification.
CAMZYOS is indicated for the treatment of adults with symptomatic New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (HCM) to improve functional capacity and symptoms.
The recommended starting dose is 5 mg orally once daily, with or without food.
Allowable titration doses are 2.5 mg, 5 mg, 10 mg, or 15 mg once daily.
Maximum recommended dose is 15 mg once daily.
Dosing is individualized based on clinical status and echocardiographic assessment (LVEF and Valsalva LVOT gradient).
Initiation is not recommended in patients with LVEF <55%. Interrupt treatment if LVEF <50% or if clinical status worsens.
Capsules must be swallowed whole; do not break, open, or chew.
Missed doses should be taken as soon as possible, but two doses should not be taken on the same day.
