This report displays the potential drug interactions for the following 2 drugs:
- Alunbrig (brigatinib)
- venetoclax
Interactions between your drugs
venetoclax brigatinib
Applies to: venetoclax and Alunbrig (brigatinib)
MONITOR: Coadministration with brigatinib may increase the plasma concentrations and risk of adverse effects of drugs that are substrates of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), organic cation transporter 1 (OCT1), and/or multidrug and toxin extrusion protein 1 (MATE1), and 2K (MATE2K). The proposed mechanism, based on in vitro data, is decreased drug clearance due to brigatinib-mediated inhibition of these transport proteins.
MANAGEMENT: Caution is advised if brigatinib is used concomitantly with drugs that are substrates of P-gp, BCRP, OCT 1, MATE 1, and/or MATE 2K transport proteins, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever brigatinib is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Drug and food interactions
venetoclax food
Applies to: venetoclax
ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of venetoclax. Relative to fasting conditions, venetoclax systemic exposure (AUC) increased by approximately 3.4-fold when administered with a low-fat meal and by 5.1- to 5.3-fold when administered with a high-fat meal.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of venetoclax. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. 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 venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.
MANAGEMENT: Venetoclax should be administered with a meal and water at approximately the same time each day. Patients should avoid consumption of grapefruit products, Seville oranges, and starfruit during treatment with venetoclax.

brigatinib food
Applies to: Alunbrig (brigatinib)
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of brigatinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. 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. Itraconazole, a potent CYP450 3A4 inhibitor, has been shown to double brigatinib systemic exposure (AUC) in healthy volunteers. Increased exposure to brigatinib may increase the risk of adverse effects such as nausea, vomiting, diarrhea, hypertension, bradycardia, hyperglycemia, visual disturbances, lymphopenia, anemia, and elevations in pancreatic enzymes and creatine phosphokinase.
Food does not significantly affect the oral bioavailability of brigatinib. When brigatinib was administered to healthy volunteers after a high-fat meal (920 calories; 59 g fat, 58 g carbohydrates, 40 g proteins), brigatinib peak plasma concentration (Cmax) decreased by 13% and systemic exposure (AUC) did not change compared to administration after overnight fasting.
MANAGEMENT: Brigatinib may be taken with or without food. Patients should avoid consumption of grapefruit and grapefruit juice during treatment with brigatinib.
