Leukemia, Acute Myeloid (AML) Clinical Trial
Official title:
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 is to determine the clinical benefit of ASP2215 therapy in participants with FMS-like tyrosine kinase (FLT3) mutated acute myeloid leukemia (AML) who are refractory to or have relapsed after first-line AML therapy as shown with overall survival (OS) compared to salvage chemotherapy, and to determine 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 will also determine the overall efficacy in event-free survival (EFS) and complete remission (CR) rate of ASP2215 compared to salvage chemotherapy.
Participants considered an adult according to local regulations at the time of signing informed consent may participate in this study. Participants will be randomized in a 2:1 ratio to receive ASP2215 or salvage chemotherapy. Participants will enter the screening period up to 14 days prior to the start of treatment. Prior to randomization, a salvage chemotherapy regimen will be pre-selected for each participant; options will include low-dose cytarabine (LoDAC), azacitidine, mitoxantrone, etoposide, and intermediate-dose cytarabine (MEC), or fludarabine, cytarabine, and granulocyte colony-stimulating factor (G-CSF) with idarubicin (FLAG-IDA). The randomization will be stratified by response to first-line therapy and pre-selected salvage chemotherapy. Participants will be administered treatment over continuous 28-day cycles. After treatment discontinuation, participants will have a pre-hematopoietic stem cell transplant (HSCT)/end-of-treatment visit within 7 days after treatment discontinuation, followed by a 30-day follow-up for safety, in which a telephone contact with the participant is sufficient unless any assessment must be repeated for resolution of treatment-related adverse events (AEs). After that, long term follow-up will be done every 3 months up to 3 years from the participant's end-of-treatment visit. ;
