® 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. CAMZYOS is a cardiac myosin inhibitor 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. ( 1 )

is contraindicated with concomitant use of: • Strong CYP2C19 inhibitors [see Warnings and Precautions (5.2) , Drug Interactions (7.1) ] • Moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers [see Warnings and Precautions (5.2) , Drug Interactions (7.1) ] • Strong CYP2C19 inhibitors. ( 4 , 5.2 ) • Moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers. ( 4 , 5.2 )

• Heart Failure : Consider interruption of CAMZYOS in patients with intercurrent illness. ( 2.1 , 5.1 ) • Drug Interactions Leading to Heart Failure or Loss of Effectiveness : Advise patients of the potential for drug interactions including with over-the-counter medications. ( 4 , 5.2 , 17 ) • Embryo-Fetal Toxicity : May cause fetal harm. Advise females of reproductive potential to use effective contraception until 4 months after the last dose. Avoid concomitant use with a combined hormonal contraceptive that contains a progestin other than norethindrone. ( 5.4 , 7.2 , 8.1 , 8.3 ) 5.1 Heart Failure CAMZYOS reduces systolic contraction and can cause heart failure or significantly reduce ventricular function. 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 [see Clinical Trial Experience (6.1) ] . Assess the patient’s clinical status and LVEF prior to and regularly during treatment and adjust the CAMZYOS dose accordingly [see Dosage and Administration (2.1) ] . New or worsening arrhythmia, dyspnea, chest pain, fatigue, palpitations, leg edema, or elevations in N-terminal pro-B-type natriuretic peptide (NT-proBNP) may be signs and symptoms of heart failure and should also prompt an evaluation of cardiac function. Asymptomatic LVEF reduction, intercurrent illnesses, and arrhythmias require …

8.1 Pregnancy Risk Summary Based on animal data, CAMZYOS may cause fetal harm when administered to a pregnant female. There are no human data on the use of CAMZYOS during pregnancy to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. The underlying maternal condition during pregnancy poses a risk to the mother and fetus (see Clinical Considerations ) . Advise pregnant females about the potential risk to the fetus with maternal exposure to CAMZYOS during pregnancy. In animal embryo-fetal development studies, mavacamten-related decreases in mean fetal body weight, reductions in fetal ossification of bones, and increases in …
