Drug Interaction Report

MONITOR: The concomitant or sequential use of epirubicin with agents known to induce hepatotoxicity may potentiate the risk of liver injury. Epirubicin undergoes elimination through the hepatobiliary system.

MANAGEMENT: Caution and clinical and laboratory monitoring for signs of liver injury are advisable before, during, or after use of epirubicin with other agents that are potentially hepatotoxic.

GENERALLY AVOID: Due to induction of CYP450 1A2, the isoenzyme primarily responsible for the metabolic clearance of vorasidenib, smoking tobacco during treatment with vorasidenib may decrease its plasma concentrations and anti-tumor effect. Clinical and pharmacokinetic data are currently lacking.

MANAGEMENT: Patient should be advised to avoid smoking tobacco during treatment with vorasidenib because it may reduce efficacy of the therapy.
