Interactions between your drugs

Major

sotorasib quizartinib

Applies to: sotorasib and quizartinib

GENERALLY AVOID: Coadministration with potent or moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations of quizartinib and its major circulating active metabolite, AC886. According to the prescribing information, quizartinib is primarily metabolized via oxidation by CYP450 3A4/5 in vitro, and AC886 is formed and metabolized by CYP450 3A4/5. Following coadministration of a single 53 mg dose of quizartinib with efavirenz, a moderate CYP450 3A4 inducer, quizartinib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 45% and 90%, respectively, while the Cmax and AUC of AC886 decreased by 68% and 96%, respectively. Reduced effectiveness of quizartinib may occur. Coadministration with a potent CYP450 3A4 inducer has not been studied, but similar if not even greater reductions in quizartinib and AC886 exposures should be expected.

MANAGEMENT: Concomitant use of quizartinib with potent or moderate CYP450 3A4 inducers should generally be avoided.

Drug and food interactions

Minor

sotorasib food

Applies to: sotorasib

Food does not appear to have a clinically significant effect on the oral bioavailability of sotorasib. When a 960 mg dose of sotorasib was administered to study patients with a high-fat, high-calorie meal (approximately 800 to 1000 calories; 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively), sotorasib peak plasma concentration (Cmax) did not change while systemic exposure (AUC 0-24 hours) increased by 25% compared to administration under fasted conditions. Sotorasib can be administered with or without food at approximately the same time each day.

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.
