venetoclax ponesimod

Applies to: venetoclax and ponesimod

MONITOR CLOSELY: Coadministration of ponesimod with antineoplastic, immunosuppressive, or other immune-modulating therapies may increase the risk of unintended additive immunosuppressive effects. Ponesimod causes reversible sequestration of lymphocytes in lymphoid tissues. When administered daily, ponesimod produces a dose-dependent reduction in peripheral lymphocyte count to 30% to 40% of baseline values, which may increase the risk of infections. Life-threatening and rare fatal infections have been reported in association with sphingosine 1-phosphate (S1P) receptor modulators. Decreased lymphocyte counts persist during chronic daily dosing and generally return to normal within 1 week after stopping the medication. Because residual pharmacodynamic effects, such as decreased peripheral lymphocytes, may persist for 1 to 2 weeks after the last dose, use of immunosuppressants during this time may also lead to additive immune effects.

MANAGEMENT: The safety and efficacy of ponesimod in combination with antineoplastic, immunosuppressive, or immune-modulating agents have not been evaluated. Caution is advised during coadministration and for 1 to 2 weeks after the last dose of ponesimod. When switching from drugs with prolonged immune effects to ponesimod, the half-life and mode of action of these drugs must be considered to avoid unintended additive immunosuppressive effects while at the same time minimizing risk of disease reactivation.

Drug and food interactions

Major

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.

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.
