Interactions between your drugs

Major

loncastuximab tesirine sirolimus protein-bound

Applies to: loncastuximab tesirine and sirolimus protein-bound

MONITOR CLOSELY: Coadministration of loncastuximab tesirine with antineoplastic, immune-modulating, immuno- or myelosuppressive therapies may potentiate the risk of severe infections, myelosuppression, and/or other unintended additive immunosuppressive effects. Serious and fatal infections, including opportunistic infections, as well as myelosuppression, including neutropenia, thrombocytopenia, and anemia have been reported with the use of loncastuximab tesirine. Concomitant use may potentiate these risks. However, clinical data are not available.

MANAGEMENT: The safety and efficacy of loncastuximab tesirine use in combination with other immuno- or myelosuppressive agents have not been evaluated. Patients receiving loncastuximab tesirine should be monitored closely for the development of signs and symptoms of infection and/or myelosuppression. The manufacturers' recommendations and institutional protocols for dosage, treatment regimens, monitoring, and management of toxicities should be consulted.

Drug and food interactions

Moderate

sirolimus protein-bound food

Applies to: sirolimus protein-bound

GENERALLY AVOID: Coadministration of protein-bound sirolimus intravenous suspension with grapefruit juice may increase the systemic exposure to sirolimus. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of sirolimus by certain compounds present in grapefruit. However, grapefruit juice primarily inhibits CYP450 3A4-mediated first-pass metabolism in the gut wall and may have limited effects on medications that are not administered orally. No formal studies evaluating the drug interaction potential of protein-bound sirolimus have been conducted. 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.

MANAGEMENT: The manufacturer recommends avoiding grapefruit and grapefruit juice during treatment with protein-bound sirolimus.

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.
