Moderate Food Interaction
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of acalabrutinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice, but has been reported for other CYP450 3A4 inhibitors. When acalabrutinib was administered with the potent CYP450 3A4 inhibitor itraconazole (200 mg once daily for 5 days) in healthy subjects, acalabrutinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 3.9- and 5.1-fold, respectively. Physiologically based pharmacokinetic (PBPK) simulations showed that moderate CYP450 3A4 inhibitors (erythromycin, fluconazole, diltiazem) increased acalabrutinib Cmax and AUC by 2- to nearly 3-fold. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased acalabrutinib exposure may potentiate the risk of toxicities such as hemorrhage, infection, cytopenias, malignancies, and atrial fibrillation or flutter.
Food may delay the absorption of acalabrutinib, but does not appear to affect the overall extent of absorption. When a single 75 mg dose of acalabrutinib was administered with a high-fat, high-calorie meal (approximately 918 calories; 59 grams carbohydrate, 59 grams fat, 39 grams protein) in healthy study subjects, mean acalabrutinib Cmax was decreased by 73% and time to reach Cmax was delayed by 1 to 2 hours compared to administration under fasted conditions. However, mean AUC was not affected.
MANAGEMENT: Acalabrutinib may be administered with or without food. Patients should avoid consumption of grapefruit and grapefruit juice during treatment with acalabrutinib.
