Summary:

      The main aim is to see how the combination of pevonedistat + venetoclax + azacitidine
      compares to venetoclax + azacitidine in adults recently diagnosed with AML who are unable to
      be treated with intensive chemotherapy.

      Participants will receive either pevonedistat + venetoclax + azacitidine or venetoclax +
      azacitidine in 28-day treatment cycles. Bone marrow samples (biopsy) will be collected
      throughout the study. Pevonedistat will be given as an intravenous (IV) infusion and
      Azacitidine will be given through IV or subcutaneous (under the skin).

      Study treatments may continue as long as the participant is receiving benefit from it.
      Participants may choose to stop treatment at any time.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Has morphologically confirmed diagnosis of AML (World Health Organization [WHO]
             criteria 2008). Participants may have newly diagnosed primary de novo AML or secondary
             AML (sAML), defined as AML after myelodysplastic syndromes (MDS) or myeloproliferative
             neoplasm (MPN), or therapy-related AML (t-AML) following cytotoxic therapy, and/or
             radiotherapy for a malignant or nonmalignant disease.

          -  Is unfit for treatment with a standard arabinosylcytosine (Ara-C) and anthracycline
             induction regimen due to age or co-morbidities defined by 1 of the following:

               -  ≥75 years of age. OR

               -  ≥18 to <75 years of age with at least one of the following:

             fraction ≤50%, or chronic stable angina).

          -  Severe pulmonary disorder (e.g., carbon monoxide lung diffusion capacity ≤65% or
             forced expiratory volume in 1 second ≤65%).

          -  Creatinine clearance (CrCl) <45 mL/min (but ≥30 mL/min as part of general eligibility
             criteria).

          -  Hepatic disorder with total bilirubin >1.5 times the upper limit of the normal range
             (ULN).

          -  Has clinical laboratory values within the following parameters (repeat within 3 days
             before the first dose of study drug if laboratory values used for randomization were
             obtained more than 3 days before the first dose of study drug):

               -  Total bilirubin ≤1.5 times the ULN except in participants with Gilbert's
                  syndrome. Participants with Gilbert's syndrome may enroll with direct bilirubin
                  ≤3 times the ULN of the direct bilirubin. Elevated indirect bilirubin due to
                  posttransfusion hemolysis is allowed.

               -  Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 times
                  the ULN.

               -  Creatinine clearance (CrCl) ≥30 mL/min (calculated by the Modification of Diet in
                  Renal Disease [MDRD] Study equation).

               -  Albumin >2.7 g/dL.

          -  White blood cell (WBC) count <25 × 10^9/L. Participants who are cytoreduced with
             leukapheresis or with hydroxyurea may be enrolled if they meet the eligibility
             criteria before starting therapy.

        Exclusion Criteria:

          -  Has history of MPN with BCR-ABL1 translocation or AML with BCR-ABL1 translocation.

          -  Has genetic diagnosis of acute promyelocytic leukemia.

          -  Is eligible for intensive chemotherapy and/or allogeneic stem cell transplantation.

          -  Has extramedullary AML without evidence of bone marrow involvement.

          -  Had prior treatment with hypomethylating agents for AML (hypomethylating agent
             treatment for prior MDS is not exclusionary).

          -  Has clinical evidence of or history of central nervous system involvement by AML.

          -  Had diagnosed or treated for another malignancy (except for adequately treated
             carcinoma in situ of any organ or nonmelanoma skin cancer) within 1 year before
             randomization or previously diagnosed with another malignancy and have any evidence of
             residual disease that may compromise the administration of pevonedistat, venetoclax or
             azacitidine. Prior MDS is also allowed, but the participant cannot have received
             treatment for MDS within 14 days before first dose of any study drug.

          -  Has a WBC count ≥25 × 10^9/L

          -  Has uncontrolled human immunodeficiency virus (HIV) infection. Note: Known HIV
             positive participants who meet the following criteria will be considered eligible:

               -  Cluster difference 4 (CD4) count >350 cells/mm^3.

               -  Undetectable viral load.

                  (CYP)-interactive agents.

               -  No history of acquired immune deficiency syndrome (AIDS)-defining opportunistic
                  infections.

          -  Participant is known to be positive for hepatitis B or C infection, with the exception
             of those with an undetectable viral load within 3 months (hepatitis B or C testing is
             not required for eligibility assessment).

          -  Has hepatic cirrhosis.

          -  Has uncontrolled coagulopathy or bleeding disorder.

          -  Has high blood pressure which cannot be controlled by standard treatments.

             guidelines.

          -  Has left ventricular ejection fraction (LVEF) <40%, based on echocardiogram or multi
             gated acquisition (MUGA) scan at screening (data to be available within last 3 months
             of screening).

          -  As infection is a common feature of AML, participants with active infection are
             permitted to enroll provided that the infection is under control and no signs of
             systemic inflammatory response beyond low grade fever that makes participant
             clinically unstable in the opinion of the investigator. Participants with uncontrolled
             infection shall not be enrolled until infection is treated and brought under control.
