Clinical Trial Summary

The purpose of this study is to explore the efficacy and safety of dasatinib 70 mg once daily as first line therapy in patients with early chronic phase (CP) chronic myeloid leukemia (CML).

Description:

A multicenter, single-arm, prospective, open-label study to detect the efficacy and safety of 70mg dasatinib by measuring rates of major molecular response (MMR) at 12 months in patients with CML-CP in China. Approximately 65 Patients will be recruited consecutively from the study sites during the enrollment period and will be given dasatinib 70 mg QD. The duration of patient participation will be 12 months.
