Moderate

alectinib food

Applies to: Alecensa (alectinib)

ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of alectinib and its major active metabolite, M4. According to the manufacturer, a high-fat, high-calorie meal increased the combined systemic exposure (AUC) of alectinib and M4 by 3.1-fold following oral administration of a single 600 mg dose of alectinib.

MANAGEMENT: To ensure maximal oral absorption, alectinib should be administered with food.
