Interactions between your drugs

Moderate

dasatinib telisotuzumab vedotin

Applies to: dasatinib and telisotuzumab vedotin

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with 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. It is not known if, and to what extent, MMAE may interact with less potent CYP450 3A4 inhibitors.

MANAGEMENT: Caution is advised when telisotuzumab vedotin is used concomitantly with 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

Major

dasatinib food/lifestyle

Applies to: dasatinib

Do not consume grapefruit or grapefruit juice during treatment with dasatinib. Grapefruit juice can significantly increase the blood levels and effects of dasatinib, which may result in excessive slowing of heart rate or other conduction disturbances and it may affect your bone marrow function, resulting in low numbers of different types of blood cells. You may be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, heart palpitations, paleness, fatigue, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, blood in phlegm, weight loss, pain or burning during urination, red or inflamed skin, or body sores during treatment with dasatinib. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
