Nilotinib is a BCR-ABL kinase inhibitor designed to overcome imatinib resistance. It binds to the inactive conformation of the ABL kinase domain with approximately 20-fold higher potency than imatinib. Nilotinib also inhibits PDGFR, c-KIT, and DDR kinases. It is active against 32 of 33 imatinib-resistant BCR-ABL mutations (not T315I).
Tmax: 3 hours. Half-life: approximately 17 hours. Protein binding: ~98%. Metabolized by CYP3A4 and CYP2C8. Bioavailability increased ~82% with food (must be fasted). Steady-state by Day 8. Excreted primarily in feces (93%).
Clinical efficacy and safety data supporting the approval are available in the full prescribing information and from the clinical trials listed below.
