Interactions between your drugs

Moderate

sipuleucel-T bosutinib

Applies to: sipuleucel-T and Bosulif (bosutinib)

MONITOR: Neither the leukapheresis procedure nor sipuleucel-T have been studied for use in combination with chemotherapy or immunosuppressive agents (e.g., systemic corticosteroids). Since sipuleucel-T is designed to stimulate the immune system, concurrent use of myelo- or immunosuppressive agents may alter the efficacy and/or safety of sipuleucel-T.

MANAGEMENT: Patients should be carefully evaluated to determine whether it is medically appropriate to reduce or discontinue chemotherapy or immunosuppressive agents prior to treatment with sipuleucel-T.

Drug and food interactions

Moderate

bosutinib food

Applies to: Bosulif (bosutinib)

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of bosutinib. When given with a high-fat meal, bosutinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.8- and 1.7-fold, respectively.

GENERALLY AVOID: Coadministration with grapefruit juice is likely to increase the plasma concentrations of bosutinib, which is primarily metabolized by CYP450 3A4. However, the interaction has not been studied. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

MANAGEMENT: Bosutinib should be administered with a meal. The consumption of grapefruit, grapefruit juice, and supplements that contain grapefruit extract should be avoided.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
