Acute myeloid leukemia (AML) with FLT3 mutation accounts for 30% of patients and is associated with a poor prognosis. Because of the FLT3 mutation, a tyrosine kinase inhibitor, midostaurin (MIDO), is added to the standard treatment with daunorubicin and cytarabine, from D8 to D21 of induction and of each consolidation cycle, followed by one year of maintenance. Venetoclax (VEN), a BCL2 inhibitor, has revolutionized the management of AML patients ineligible for intensive chemotherapy, in combination with azacitidine or cytarabine. The investigators hypothesize that a four-drug induction regimen (daunorubicin+cytarabine+MIDO+VEN) will increase complete remission (CR) rate without measurable residual disease (MRD) and improve event free survival (EFS), relapse free survival (RFS) and overall survival (OS) of this subgroup of patients with unmet medical need.
Screening of 226 clinical trials on ClinTrial.gov showed 26 studies evaluating intensive chemotherapy (daunorubicin+cytarabine) and VEN but none in combination with MIDO even though 30% of patients eligible for intensive chemotherapy do receive such a regimen. Intensive chemotherapy and MIDO showed a significant median overall survival improvement but a moderate increase of patients still alive at 3 years, around an additional 10% 1. Moreover, MIDO does not allow an increase in proportion of patients in first complete remission (CR1) or CR with incomplete hematologic recovery (CRi1) after the 1st induction course. Another study with a second-generation tyrosine kinase inhibitor, quizartinib (QuANTUM-First) showed that among patients with CR1/CRi1, 42% had a measurable residual disease (MRD) \<10-4 in quizartinib arm versus 38% in placebo arm, despite, here again, a significant median overall survival improvement 2. These data show that tyrosine kinase inhibitors do not increase the rate of complete remission (CR) without MRD, explaining probably the moderate improvement of definitive cure rate. The investigators hypothesize that adding VEN to this standard treatment will increase complete remission rate without MRD and improve OS of patients with FLT3-mutated AML. Two clinical trials evaluated VEN in AML patients eligible to intensive chemotherapy and showed high levels of complete remission without MRD and a manageable toxicity profile, related to VEN start date and duration of exposure 3,4. In the current study, the investigators propose the following schedule to find the best treatment sequence while preventing the risk of myelosuppression, based on available data from the two clinical trials previously presented: In schedule A, VEN will be used from D8 to D14 to harness the synergy between FLT3 and BCL2 inhibition; in schedule B, VEN will be used from D4 to D10 to harness the synergy between chemotherapy and BCL2 inhibition then between FLT3 and BCL2 inhibition. If previous schedules A and B are safe, the investigators propose to prolong VEN exposure to 10 days allowing longer association between MIDO and VEN with a schedule C with VEN from D8 to D17 and finally a schedule D with VEN from D4 to D13. Follow-up will include up to 3 consolidation courses with intermediate dose cytarabine and VEN according to previous French phase 2 clinical trial COVENIDAC 5 and MIDO in this label from D8 to D21. Finally, patients will receive 12 cycles maintenance by MIDO with VEN D1-D14 in 28-day cycles. Patients will undergo allogeneic stem cell transplantation (HSCT) according to standard indications and procedures.

Main inclusion criteria:
Documented FLT3 gene mutation (-TKD D835 or I836 or -ITD or both) FLT3-ITD is assessed by DNA fragment analysis. Positivity is defined as an ITD/wt ratio of ≥ 0.05 (5%).
FLT3-TKD D835 or I836 is assessed by NGS. Positivity is defined as a VAF > 5%.
Main exclusion criteria:
Drug: Venetoclax in association with 3+7 and midostaurin
(1) induction with daunorubicin 60 mg/m²/day for 3 days, cytarabine 200 mg/m²/day for 7 days and MIDO 50 mg x 2/day from D8 to D21, (2) consolidation with 3 courses of intermediate dose cytarabine 1-1.5 gr/m² x 2/day at D1, D2 and D3 and MIDO 50 mg x 2/day from D8 to D21 in 35-day cycles, and (3) a maintenance with MIDO 50 mg x 2/day from D1 to D28 in 28-day cycles for 12 cycles. VEN is a highly potent BCL-2 inhibitor, synergistic with cytarabine, anthracyclines, and tyrosine kinase inhibitors. In the current study we aim at harnessing this synergistic effect with standard chemotherapy (cytarabine, anthracyclines) and tyrosine kinase inhibitor (MIDO) during induction, consolidation and maintenance. Our strategy aims at determining the best schedule of combination during induction chemotherapy whereas we do not foresee specific safety issues during consolidation and maintenance strategy
