Gilteritinib vs Midostaurin in FLT3 Mutated Acute Myeloid Leukemia

Study Summary

Eligible untreated patients with FLT3 acute myeloid leukemia (AML) between the ages of 18 and 70 will be randomized to receive gilteritinib or midostaurin during induction and consolidation. Patients will also receive standard chemotherapy of daunorubicin and cytarabine during induction and high-dose cytarabine during consolidation. Gilteritinib, is an oral drug that works by stopping the leukemia cells from making the FLT3 protein. This may help stop the leukemia cells from growing faster and thus may help make chemotherapy more effective. Gilteritinib has been approved by the Food and Drug Administration (FDA) for patients who have relapsed or refractory AML with a FLT3 mutation but is not approved by the FDA for newly diagnosed FLT3 AML, and its use in this setting is considered investigational. Midostaurin is an oral drug that works by blocking several proteins on cancer cells, including FLT3 that can help leukemia cells grow. Blocking this pathway can cause death to the leukemic cells. Midostaurin is approved by the FDA for the treatment of FLT3 AML. The purpose of this study is to compare the effectiveness of gilteritinib to midostaurin in patients receiving combination chemotherapy for FLT3 AML.

Primary Outcome

FLT3 mutation negative (evaluated by polymerase chain reaction \[PCR\]) Composite Complete Response (CRc) \[includes CR and CRi\] rate after induction treatment and complete MRD assessment. The cut points used for FLT3 mutation negative are 1% (equivalent to 10-2) for FLT3-TKD and 10-4 for FLT3-ITD.
