Induction chemotherapy and molecular MRD influence outcomes in KMT2A -rearranged AML

ABSTRACT: We analyzed 217 patients with KMT2A-rearranged acute myeloid leukemia (AML) in 2 large sequential randomized trials. Those randomized to FLAG-Ida (fludarabine, cytarabine, granulocyte colony-stimulating factor, idarubucin) had markedly lower rates of relapse than other chemotherapy regimens. Molecular measurable residual disease assessment after cycle 2 was strongly prognostic for relapse and death. The trials were registered at the ISRCTN Registry as AML17 ISRCTN55675535 and AML19 ISRCTN78449203.
