MONITOR: Coadministration with weak inducers of CYP450 3A4 may reduce the plasma levels and effects of lazertinib, which is primarily metabolized by the isoenzyme. In a phase 1 study of healthy adult participants, concomitant use of the strong CYP450 3A4 inducer rifampin reduced the peak plasma concentration (Cmax) and systemic exposure (AUC) of lazertinib by 72% and 83%, respectively. Likewise, a pharmacokinetic model predicted that concomitant use with the moderate CYP450 3A4 inducer efavirenz would decrease lazertinib's steady state Cmax and AUC by at least 32% and 44%, respectively. Clinical data with less potent CYP450 3A4 inducers are not available.
MANAGEMENT: The potential for diminished pharmacologic effects of lazertinib should be considered if coadministration with a weak CYP450 3A4 inducer is clinically necessary. An alternative concomitant medication with no potential to induce CYP450 3A4 may be required.
Drug and food/lifestyle interactions

Grapefruit juice may increase the blood levels of mavacamten and increase the risk of heart failure, a condition where the heart is unable to pump blood adequately to meet the body's needs. Your risk may be further increased if you develop a serious infection or irregular heartbeat during treatment with mavacamten. You should avoid the consumption of grapefruit and grapefruit juice while taking this medication. Talk to your doctor if you have any questions or concerns. You should seek medical attention if you experience signs and symptoms of heart failure such as shortness of breath, chest pain, fatigue, swelling in your legs, palpitations, or rapid weight gain. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
