Gilteritinib vs Midostaurin in FLT3 Mutated Acute Myeloid Leukemia

Approximately one third of patients with AML have a particular change in their leukemia cells (called a mutation) in a gene called FLT3. The presence of a FLT3 mutation can be used to direct treatment options. This is an open-label phase II study. Patients will receive standard chemotherapy of daunorubicin and cytarabine during Induction and high-dose cytarabine during Consolidation. Patients will be randomized to gilteritinib or midostaurin. After approximately 90 patient's complete treatment, a review of the effectiveness of gliteritinib compared to midostaurin will be done. If gilteritinib is not as effective as midostaurin, the study may be stopped. Bone marrow aspirate and biopsy will be done on Day 21 after start of Induction and after Induction to assess response. Patients with a complete response may proceed to consolidation chemotherapy. Another bone marrow aspirate and biopsy will be done after the first cycle of consolidation is complete. Mandatory prescreening bone marrow and/or blood samples are required for FLT3 testing. Any left-over samples will be requested for future research (optional). Mandatory bone marrow samples for research are required after Induction and if patient receives Consolidation, after the first cycle of Consolidation.
