cycloSPORINE enfortumab vedotin

Applies to: cyclosporine and enfortumab vedotin

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations and effects of unconjugated monomethyl auristatin E (MMAE). Enfortumab vedotin is an antibody-drug conjugate (ADC) that releases MMAE, a microtubule-disrupting agent believed to induce cell cycle arrest and apoptosis, via proteolytic cleavage. MMAE has been shown in vitro to be primarily metabolized by CYP450 3A4. According to physiologically-based pharmacokinetic (PBPK) modeling, concomitant use of enfortumab vedotin with ketoconazole, a dual P-gp and strong CYP450 3A4 inhibitor, is predicted to increase unconjugated MMAE peak plasma concentration (Cmax) by 15% and systemic exposure (AUC) by 38%, with no change in ADC exposure. In one case report, a 70-year-old man on stable doses of raltegravir and the CYP450 3A4 inhibitors darunavir and ritonavir, experienced severe toxicity after receiving 2 infusions of enfortumab vedotin (1.25 mg/kg on days 1 and 8 of his 28-day cycle). He was hospitalized with a severe generalized pruritic rash, thrush, mucositis, anorexia, diarrhea, acute kidney injury, and pancytopenia. Enfortumab vedotin was withheld and the patient returned to baseline after being treated with supportive measures. About a year later, he was rechallenged with enfortumab vedotin while on an antiretroviral regimen consisting of dolutegravir, doravirine, and valacyclovir. He was able to tolerate a reduced dose of 1 mg/kg, with mild expected toxicity including skin blisters and peripheral neuropathy. It is not known if, and to what extent, enfortumab vedotin may interact with less potent CYP450 3A4 inhibitors.

MANAGEMENT: Patients should be closely monitored for development or exacerbation of toxicities including, but not limited to skin reactions (maculopapular rash, pruritus, symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), bullous dermatitis, exfoliative dermatitis, palmar-plantar erythrodysesthesia, Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN)); hyperglycemia (including diabetic ketoacidosis); pneumonitis or interstitial lung disease; peripheral neuropathy; and ocular disorders (dry eyes, keratitis, blurred vision, limbal stem cell deficiency). Refer to the product labeling for dose adjustment or discontinuation of therapy recommendations depending on the severity or Grade of the adverse reactions, should they occur.

Drug and food interactions

Moderate

cycloSPORINE food

Applies to: cyclosporine

GENERALLY AVOID: Administration with grapefruit juice (compared to water or orange juice) has been shown to increase blood concentrations of cyclosporine with a relatively high degree of interpatient variability. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.

GENERALLY AVOID: Administration with red wine or purple grape juice may decrease blood concentrations of cyclosporine. In 12 healthy volunteers, 12 ounces total of a merlot consumed 15 minutes prior to and during cyclosporine administration (single 8 mg/kg dose of Sandimmune) decreased cyclosporine peak blood concentration (Cmax) and systemic exposure (AUC) by 38% and 30%, respectively, compared to water. The time to reach peak concentration (Tmax) doubled, and oral clearance increased 50%. Similarly, one study were 12 healthy patients were administered purple grape juice and a single dose of cyclosporine showed a 30% and a 36% decrease in cyclosporine systemic exposure (AUC) and peak blood concentration (Cmax), respectively. The exact mechanism of interaction is unknown but may involve decreased cyclosporine absorption.

MONITOR: Food has been found to have variable effects on the absorption of cyclosporine. There have been reports of impaired, unchanged, and enhanced absorption during administration with meals relative to the fasting state. The mechanisms are unclear. Some investigators found an association with the fat content of food. In one study, increased fat intake resulted in significantly increased cyclosporine bioavailability and clearance. However, the AUC and pharmacodynamics of cyclosporine were not significantly affected, thus clinical relevance of these findings may be minimal.

MANAGEMENT: Patients receiving cyclosporine therapy should be advised to either refrain from or avoid fluctuations in the consumption of grapefruits and grapefruit juice. Until more data are available, the consumption of red wine or purple grape juice should preferably be avoided or limited. All oral formulations of cyclosporine should be administered on a consistent schedule with regard to time of day and relation to meals so as to avoid large fluctuations in plasma drug levels.

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.
