Treatments tested in this trial
Venetoclax
DrugVenetoclax will be administered in Induction cycle 1, Induction cycle 2 and in the chemo consolidation therapy in addition to the standard chemotherapy
Placebo
DrugPlacebo will be administered in Induction cycle 1, Induction cycle 2 and in the chemo consolidation therapy in addition to the standard chemotherapy
Standard chemotherapy
Combination productInduction cycle 1: Patients will receive cytarabine 200 mg/m2 continuous IV (days 1-7) and daunorubicin 60 mg/m2 IV (days 1-3). Induction cycle 2: Patients ≤ 60 yrs will receive cytarabine 1000 mg/m2 BID (3h IV), days 1-4, and daunorubicin 60 mg/m2 IV (days 1-3). Patients \>60 yrs will receive cytarabine 1000 mg/m2 BID (3h IV), days 1-4 without daunorubicin. Consolidation chemotherapy with intermediate doses of cytarabine. Patients ≤60 yrs will receive up to 3 cycles of IDAC (single dose 1500 mg/m2 every 12 hours, days 1-3). Patients who are \>60 yrs will receive up to 3 cycles of IDAC with single doses of 1000 mg/m2, every 12 hours, days 1-3. In patients \>60 yrs less than 3 cycles of IDAC or dose-reduced IDAC (500 mg/m2 per single dose) may be given based on an individual risk assessment.
Allogeneic stem cell transplantation
Other interventionGenerally, patients will proceed to allogeneic HCT upon completion of remission induction chemotherapy. It is however allowed, as per investigator's discretion, for a patient to receive 'bridging' consolidation chemotherapy in exceptional cases of delay towards transplantation. At baseline, HLA-compatible donor search must be initiated as soon as possible, first among siblings and second in the world donor bank for unrelated donors or cord blood. In order to avoid inappropriate delay in cases where no suitable sibling is present, high-resolution HLA typing should be performed immediately after registration, enabling a more rapid matched-unrelated donor search. In case no sibling or unrelated donor can be identified, haploidentical allogeneic HCT is allowed. Conditioning and GVHD prophylaxis will take place according to institutional guidelines. Patients who undergo allogeneic HCT will not receive venetoclax during conditioning, engraftment or after hematologic recovery.
Treatment groups
Trial outcomes
Primary outcomes
Event Free Survival (EFS)
EFS in adult patients with newly diagnosed AML, defined as the time from randomization to treatment failure, death from any cause, or relapse after achieving CR or CRi, or start of new therapy due to confirmed molecular relapse whichever occurs first. Treatment failure is defined as not attaining CR or CRi after induction chemotherapy, and EFS event time for treatment failure is Day 1 of post-randomization
Frequency of dose-limiting toxicities (DLTs) during the observation period (Primary safety endpoint during dose-finding phase)
Frequency of dose-limiting toxicities (DLTs) during the observation period (from start of cycle 1 up to a maximum of day 42, or until the start of cycle 2)
Secondary outcomes
Overall Survival (OS)
OS in patients with newly diagnosed AML
CR/CRi rate
Complete remission (CR/CRi) rate in newly diagnosed AML patients defined as the proportion of AML patients with CR/CRi after induction chemotherapy
CR rate
Complete remission (CR) rates in newly diagnosed AML patients defined as the proportion of AML patients with CR after induction chemotherapy
Event Free Survival (EFS) including CRh
EFS in adult patients with newly diagnosed AML, defined as the time from randomization to treatment failure, death from any cause, or relapse after achieving CR, CRh or CRi, or start of new therapy due to confirmed molecular relapse whichever occurs first. Treatment failure is defined as not attaining CR, CRh or CRi by end of induction chemotherapy, i.e. if a patient's best response during or at completion of the induction treatment is less than CR/CRh/CRi
Other outcomes
Rates of CR+CRi in newly diagnosed AML patients after induction 1
Rates of CR+CRi in newly diagnosed AML patients defined as proportion of AML patients achieving CR/CRi after first course of induction
Rates of CR in newly diagnosed AML patients after induction 1
Rates of CR in newly diagnosed AML patients defined as proportion of AML patients achieving CR after first course of induction
EFS in newly diagnosed AML patients across different patient subgroups
EFS in newly diagnosed AML patients across different groups are defined based on prognostic characteristics including age at randomization , risk category according to ELN 2022 recommendations, as well as specific AML genotypes
OS in newly diagnosed AML patients across different patient subgroups
OS in newly diagnosed AML patients across different groups are defined based on prognostic characteristics including age at randomization , risk category according to ELN 2022 recommendations, as well as specific AML genotypes
