Interactions between your drugs

Major

telaprevir telisotuzumab vedotin

Applies to: telaprevir and telisotuzumab vedotin

Consumer information for this interaction is not currently available.

MONITOR CLOSELY: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of unconjugated monomethyl auristatin E (MMAE), the anti-mitotic and cytotoxic component of telisotuzumab vedotin. Telisotuzumab vedotin is an antibody-drug conjugate (ADC) that releases MMAE via proteolytic cleavage, and MMAE has been shown in vitro to be primarily metabolized by CYP450 3A4. MMAE systemic exposure (AUC) is predicted to increase by 1.4-fold following concomitant administration of telisotuzumab vedotin with the potent CYP450 3A4 inhibitor ketoconazole.

MANAGEMENT: Caution is advised when telisotuzumab vedotin is used concomitantly with potent CYP450 3A4 inhibitors. Patients should be closely monitored for development or exacerbation of toxicities such as ocular surface disorders (e.g., dry eyes, keratitis, blurred vision), peripheral neuropathy, interstitial lung disease/pneumonitis, and peripheral edema. If serious adverse reactions occur, the dosing of telisotuzumab vedotin should be adjusted or withheld as necessary in accordance with the product labeling.

Drug and food/lifestyle interactions

Moderate

telaprevir food/lifestyle

Applies to: telaprevir

Food significantly increases the absorption of telaprevir. Within 30 minutes before you take each dose of telaprevir, you should eat a meal or snack containing approximately 20 grams of fat. Taking it on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication. Examples of some foods that could be taken with telaprevir include: bagel with cream cheese; half cup of nuts; 3 tablespoons of peanut butter; 1 cup of ice cream; 2 ounces of American or cheddar cheese; 2 ounces of potato chips; or half cup of trail mix. Talk to your healthcare provider if you have additional questions about how to take telaprevir.
