Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this multi-center, open-label, no control,prospective clinical trial, a total of 30 relapsed acute myeloid leukemia with t(8;21) translocation and KIT D816 mutation patients will be enrolled. Dasatinib 70 mg twice a day will be administrated for two weeks from day 1 of re-induction chemotherapy. The purpose of current study is to determine the clinical efficacy and tolerability of combination therapy of dasatinib with multi-agent chemotherapy in relapsed acute myeloid leukemia with t(8;21) translocation and KIT D816 mutation.
