Interactions between your drugs

Moderate

eliglustat tebentafusp

Applies to: Cerdelga (eliglustat) and tebentafusp

MONITOR: Coadministration with tebentafusp may increase the plasma concentrations of drugs that are metabolized by CYP450 pathways. The formation of hepatic CYP450 enzymes is down-regulated by increased levels of certain proinflammatory cytokines that are transiently released during initiation of tebentafusp treatment. Thus, tebentafusp may suppress CYP450 enzymes resulting in increased exposures of some CYP450 substrates. Clinical data are currently lacking but risk of an interaction is expected to be greatest during the first 24 hours of the first 3 tebentafusp doses.

MANAGEMENT: Caution is advised when tebentafusp is coadministered with drugs that are CYP450 substrates, particularly those with narrow therapeutic ranges (e.g., antiarrhythmics, anticonvulsants, immunosuppressants, theophylline) or sensitive substrates where increases in plasma levels may be significant or undesirable (e.g., statins, benzodiazepines, opioids). Clinical and/or laboratory monitoring should be considered following the initiation or withdrawal of tebentafusp, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly.

Drug and food interactions

Major

eliglustat food

Applies to: Cerdelga (eliglustat)

GENERALLY AVOID: Grapefruit juice may significantly increase the systemic exposure to eliglustat. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because eliglustat is predicted to cause prolongation of the PR, QTc, and QRS cardiac intervals at substantially elevated plasma concentrations, consumption of grapefruit juice during treatment may increase the risk of bradycardia, atrioventricular block, cardiac arrest, and serious ventricular arrhythmias such as torsade de pointes.

MANAGEMENT: Patients treated with eliglustat should avoid consumption of grapefruit and grapefruit juice.

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.
