Phase 1/2 evaluating the addition of venetoclax to standard 3+7 and midostaurin induction treatment in patients with FLT3-mutated Acute Myeloid Leukemia eligible to intensive chemotherapy - MIDOVEN

FLT3-mutated Acute Myeloid Leukemia

Proportion of participants with DLTs during the induction phase of VEN in combination with 3+7+MIDO, Proportion of participants with CR/CRi without MRD, after induction chemotherapy with the RP2S, measured by MFC according to ELN2022 (evaluated as soon as possible after hematological recovery or up to D56)
