Interactions between your drugs

Moderate

colchicine epcoritamab

Applies to: Colcrys (colchicine) and epcoritamab

MONITOR: Coadministration with epcoritamab may increase the plasma concentrations of drugs that are substrates of CYP450 isoenzymes. Initiation of epcoritamab treatment causes transient release of cytokines that may suppress CYP450 isoenzymes, although the potential for an interaction has not been studied. According to the manufacturer, the highest drug-drug interaction risk would be from the first dose on the first day of cycle 1, up to 14 days after the first 48 mg dose on day 15 of cycle 1, as well as during and after cytokine release syndrome.

MANAGEMENT: Caution is advised when epcoritamab is administered with drugs that are metabolized by CYP450 isoenzymes, particularly those with a narrow therapeutic range, where minimal changes to concentration may lead to significant adverse reactions, such as carbamazepine, colchicine, cyclosporine, disopyramide, phenytoin, quinidine, theophylline, warfarin, macrolide immunosuppressants, vinca alkaloids, and some narcotic analgesics. Clinical and/or laboratory monitoring are recommended, particularly at the initial phase of treatment with epcoritamab as well as during and after cytokine release syndrome, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly.

Drug and food interactions

Major

colchicine food

Applies to: Colcrys (colchicine)

GENERALLY AVOID: Coadministration with grapefruit juice may increase the serum concentrations of colchicine. Clinical toxicity including myopathy, neuropathy, multiorgan failure, and pancytopenia may occur. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism and P-glycoprotein efflux in the gut wall by certain compounds present in grapefruits. A published case report describes an eight-year-old patient with familial Mediterranean fever who developed acute clinical colchicine intoxication after ingesting approximately one liter of grapefruit juice per day for two months prior to hospital admission while being treated with colchicine 2 mg/day. Her condition progressed to circulatory shock and multiorgan failure, but she recovered with supportive therapy after 24 days in the hospital. In a study of 21 healthy volunteers, administration of 240 mL grapefruit juice twice a day for 4 days was found to have no significant effect on the pharmacokinetics of a single 0.6 mg dose of colchicine. However, significant interactions have been reported with other CYP450 3A4 inhibitors such as clarithromycin, diltiazem, erythromycin, ketoconazole, ritonavir, and verapamil.

MANAGEMENT: Patients treated with colchicine should be advised to avoid the consumption of grapefruit and grapefruit juice, and to contact their physician if they experience symptoms of colchicine toxicity such as abdominal pain, nausea, vomiting, diarrhea, fatigue, myalgia, asthenia, hyporeflexia, paresthesia, and numbness.

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.
