Abstract

Dasatinib is a highly potent BCR-ABL kinase inhibitor with established efficacy and safety in imatinib-resistant or -intolerant patients with chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia. In the global phase III DASISION trial in patients with newly diagnosed chronic phase CML (CML-CP), dasatinib was found to have an acceptable safety profile and demonstrated significantly faster and higher rates of complete cytogenetic response (CCyR) and major molecular response (MMR) compared with imatinib. Here, we report the results of a subset analysis of Japanese patients enrolled in the DASISION trial, showing safety and efficacy profiles generally consistent with patients enrolled worldwide, including higher response rates (CCyR, MMR) with dasatinib compared with imatinib and similar high rates of progression-free and overall survival with both therapies. However, the small sample size of the present study limits the strength of these conclusions, and further exploration is needed to confirm any differences observed in Japanese patients compared with the total treated population. These findings support the use of dasatinib 100 mg QD as a first-line treatment in Japanese patients with newly diagnosed CML-CP.
