Imatinib as Second-Line Treatment Drug for CML Patients Intolerant to Nilotinib

Abstract

To explore the individualized treatment for patient with chronic phase chronic myeloid leukemia(CML-CP). The clinical data and treatment process of one CML-CP patient which intolerated to nilotinib were analyzed. Nilotinib was given to the patient once the diagnosis of CML-CP was set. Although major molecular remission (MMR) and complete cytogenetic remission (CCyR) were obtained during treatment for 3 months, a grade 3-4 hepatotoxicity appeared in the course of treatment.With drug reduction and symptomatic treatment, nilotinib was discontinued after 3 withdrawals and replaced with imatinib in January 11, 2015. The patients achieved MMR and CCyR at 7 months after imatinib replacement. At present, the patient tolerated well without any adverse events. Imatinib can be used as a second-line treatment drug for CML patients who was intolerant to nilotinib, and with less adverts, good effect and so on.
