Sumario:OBJECTIVE: To evaluate the early hematologic, cytogenetic and molecular responses in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (CML-CP) and initially treated with a generic imatinib (Xinwei), manufactured by Jiansu Hansoh Pharmaceutical Group Co., Ltd. METHODS: 107 newly diagnosed patients of CML-CP, whose ages were above 18-year-old and who had never received any tyrosine kinase inhibitor (TKI) were treated with Xinwei 400 mg QD. The hematologic, cytogenetic and molecular responses were assessed at 3- and 6-month, and adverse effects were evaluated throughout the study. RESULTS: 107 patients were treated with Xinwei for at least 3 months, 54 of them were treated for 6 months or more. At 3-month, the complete hematologic responses (CHR) rate were 98.1% (105/107); 47/57 (82.5%) patients achieved major cytogenetic response (MCyR), and 20/57 (35.1%) patients complete cytogenetic response (CCyR); BCR-ABL(IS) was ≤10% in 77/106 patients (72.6%), 11 of them (10.4%) achieved major molecular response (MMR, BCR-ABL(IS) was ≤0.1%). At 6-month, the CHR rate was 100% (54/54); 28/39 patients (71.8%) achieved CCyR; BCR-ABL(IS) was ≤1% in 37/54 patients (68.5%), 18 of them (33.3%) achieved MMR. The grade Ⅲ leukopenia, thrombocytopenia and anemia rates were 19.5%, 23.0% and 13.8%, respectively. No grade Ⅳ hematologic toxicity occurred. The common non-hematologic toxicities were edema (74.7%), nausea (48.3%), bone pain (42.5%), rash (36.8%), diarrhea (34.5%), fever (23.0%), cramp (11.5%) and impaired liver function(3.4%). No patient experienced grade Ⅳ non-hematologic toxicity. No adverse effects related death occurred. CONCLUSION: Our results revealed the excellent early haematology, cytogenetic and molecular responses and safety of Xinwei in treating patients with CML-CP.
