Interactions between your drugs
brentuximab vedotin tezacaftor
Applies to: Adcetris (brentuximab) and Alyftrek (deutivacaftor / tezacaftor / vanzacaftor)
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with potent CYP450 3A4 inhibitors or P-glycoprotein (P-gp) inhibitors may increase the plasma concentrations of monomethyl auristatin E (MMAE), the microtubule-disrupting component of brentuximab vedotin. MMAE is primarily metabolized by CYP450 3A4 and has been found in vitro to be a substrate of the P-gp efflux transporter. In study subjects, administration of brentuximab vedotin with the potent CYP450 3A4 and P-gp inhibitor ketoconazole resulted in an approximately 34% increase in MMAE systemic exposure (AUC).
MONITOR: Coadministration of brentuximab vedotin with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Serious cases of hepatotoxicity, some fatal, have occurred in patients treated with brentuximab vedotin. Cases were consistent with hepatocellular injury, including elevations of transaminases and/or bilirubin, and typically occurred after the first dose or after a rechallenge. Preexisting liver disease and elevated baseline liver enzymes may also increase the risk.
MANAGEMENT: Caution is advised when brentuximab is used with potent CYP450 3A4 inhibitors (e.g., azole antifungal agents, clarithromycin, erythromycin, nefazodone, ritonavir, telithromycin) or P-gp inhibitors (e.g., protein kinase inhibitors, abiraterone, amiodarone, azithromycin, cyclosporine, dronedarone, ivacaftor) that are also potentially hepatotoxic. Close monitoring for adverse effects including neutropenia, infection, peripheral neuropathy, and hepatotoxicity is recommended. Patients should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, right upper quadrant pain, dark urine, pale stools, and jaundice. Liver enzymes and bilirubin should be measured before and during treatment, especially in patients with underlying hepatic disease or marked baseline transaminase elevations. Patients experiencing new, worsening, or recurrent hepatotoxicity may require a delay, change in dosage, or discontinuation of brentuximab vedotin in accordance with the product labeling.
brentuximab vedotin vanzacaftor
Applies to: Adcetris (brentuximab) and Alyftrek (deutivacaftor / tezacaftor / vanzacaftor)

Preexisting liver disease and elevated baseline liver enzymes may also increase the risk.
MANAGEMENT: The risk of hepatic injury should be considered when brentuximab vedotin is used with other agents that are potentially hepatotoxic (e.g., acetaminophen; alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; cyclosporine (high dosages); disulfiram; endothelin receptor antagonists; interferons; ketolide and macrolide antibiotics; kinase inhibitors; minocycline; nonsteroidal anti-inflammatory agents; HIV reverse transcriptase inhibitors; proteasome inhibitors; retinoids; sulfonamides; tamoxifen; thiazolidinediones; tolvaptan; vincristine; zileuton; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, lomitapide, mipomersen, niacin, and statins; herbals and nutritional supplements such as black cohosh, chaparral, comfrey, DHEA, kava, pennyroyal oil, and red yeast rice). Patients should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, right upper quadrant pain, dark urine, pale stools, and jaundice. Liver enzymes and bilirubin should be measured before and during treatment, especially in patients with underlying hepatic disease or marked baseline transaminase elevations.

Drug and food interactions
tezacaftor food
Applies to: Alyftrek (deutivacaftor / tezacaftor / vanzacaftor)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of tezacaftor, deutivacaftor, and vanzacaftor. 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. The risk and/or severity of serious side effects such as liver damage may be increased.
ADJUST DOSING INTERVAL: Administration with fat-containing food may increase the oral bioavailability of vanzacaftor and deutivacaftor. Administration with a fat containing meal increased vanzacaftor systemic exposure (AUC) by 4- (low-fat meal) to 6- (high-fat meal) fold. While deutivacaftor AUC increased approximately 3- (low-fat meal) to 4- (high-fat meal) fold, relative to administration in a fasting state. Tezacaftor exposure is not significantly affected by administration of fat-containing foods.
MANAGEMENT: Patients treated with tezacaftor, deutivacaftor, vanzacaftor -containing medications should avoid consumption of grapefruit juice and any food that contains grapefruit. To improve absorption, patients should be advised to take vanzacaftor and/or deutivacaftor containing medications with fat-containing foods such as eggs, avocados, nuts, meat, butter, peanut butter, cheese pizza, and whole-milk dairy products at approximately the same time of the day. A typical cystic fibrosis diet will satisfy this requirement.
