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

Moderate

cobimetinib food

Applies to: cobimetinib

MONITOR: Grapefruit juice may increase the plasma concentrations of orally administered drugs that are substrates of the CYP450 3A4 isoenzyme, such as cobimetinib. However, the interaction seems to affect primarily those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability), presumably due to the fact that grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4. Because pharmacokinetic interactions involving grapefruit juice are often subject to a high degree of interpatient variability, the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of cobimetinib. Grapefruit and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact with these drugs.

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.
