Abstract

Objective: Nilotinib is a BCR-ABL1 tyrosine kinase inhibitor approved for the treatment of patients with chronic myeloid leukemia in chronic phase (CML-CP). This study was the first prospective evaluation of the efficacy and safety of nilotinib in Turkish patients with newly diagnosed CML-CP. The primary endpoint of the study was the rate of major molecular response (MMR; BCR-ABL10.1% on the International Scale [BCR-ABL1(IS)]) by 12months.Methods: Patients with newly diagnosed CML-CP were treated with nilotinib 300mg twice daily. This analysis was based on the first 12months of follow-up in a 24-month study.Results and Conclusions: Of 112 patients enrolled, 66.1% (80% CI, 59.7-72.0%) achieved MMR and 22.3% achieved a deep molecular response of MR4.5 (BCR-ABL1(IS) 0.0032%) by 12months. During the first year of treatment, 1 patient progressed to blast crisis and 2 patients died. Safety results were consistent with previous studies. Most adverse events (AEs) were grade 1/2. Most frequently reported nonhematologic AEs of any grade were elevations in bilirubin, alanine aminotransferase, and triglycerides. These results support the use of nilotinib 300mg twice daily as a standard-of-care treatment option for patients with newly diagnosed CML-CP.
