The Efficacy and Safety of Switching to Flumatinib Versus Dasatinib After Imatinib-related Low-grade Adverse Events in CML-CP Patients

The purpose of this study is to explore the efficacy and safety of switching to flumatinib versus dasatinib after imatinib-related low-grade adverse events in patients with chronic myeloid leukemia in chronic phase (CML-CP) in China. This is a post-marketing, interventional, double-arm, prospective, open-label, randomized controlled study in CML-CP patients in China.
