GENERALLY AVOID: Coadministration with osimertinib may alter the plasma concentrations of drugs that are primarily metabolized by CYP450 3A4. In vitro, osimertinib has been shown to be a competitive inhibitor as well as inducer of CYP450 3A4. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: Concomitant use of osimertinib and sensitive CYP450 3A4 substrates or substrates with narrow therapeutic ranges should generally be avoided. These drugs include, but are not limited to: alfentanil, cisapride, colchicine, cyclosporine, fentanyl, ivacaftor, lovastatin, simvastatin, oral midazolam, triazolam, pimozide, quinidine, sildenafil, ergot derivatives, macrolide immunosuppressants, and vinca alkaloids.
