A Phase 3 Open-Label, Multicenter, Randomized Study of ASP2215 Versus Salvage Chemotherapy in Patients With Relapsed or Refractory Acute Myeloid Leukemia (AML) With FLT3 Mutation

The purpose of this study was to determine the clinical benefit of ASP2215 therapy in participants with FMS-like tyrosine kinase (FLT3) mutated acute myeloid leukemia (AML) who were refractory to or had relapsed after first-line AML therapy as shown with overall survival (OS) compared to salvage chemotherapy, and determined the efficacy of ASP2215 therapy as assessed by the rate of complete remission and complete remission with partial hematological recovery (CR/CRh) in these participants. This study also determined the overall efficacy in event-free survival (EFS) and complete remission (CR) rate of ASP2215 compared to salvage chemotherapy.
