摘要: Background Resistance to imatinib mesylate can occur in chronic myelogenous leukemia (CML). Preclinical vitro studies have shown that nilotinib (AMN107), a new BCR-ABL tyrosine kinase inhibitor, is more potent than against CML cells by factor of 20 50. Methods In phase 1 dose-escalation study, we assigned 119 patients with imatinib-resistant or acute lymphoblastic (ALL) receive orally at doses 50 mg, 100 200 400 600 800 and 1200 mg once daily twice daily. Results Common adverse events were myelosuppression, transient indirect hyperbilirubinemia, rashes. Of 33 the blastic disease, 13 had hematologic response 9 cytogenetic response; 46 accelerated phase, 22 11 12 complete remission. Conclusions Nilotinib has relatively favorable safety profil...
