Purpose

The purpose of this study is to determine whether the combination of pevonedistat + venetoclax + azacitidine improves event-free survival (EFS) compared with venetoclax + azacitidine in patients with newly diagnosed acute myeloid leukemia (AML) who are unfit for intensive chemotherapy.

Detailed Description

      The drug being tested in this study is called Pevonedistat. Pevonedistat is being tested to
      treat people who have AML. This study will compare the improvement in EFS in Arm A:
      pevonedistat + venetoclax + azacitidine combination arm group when compared with Arm B:
      venetoclax + azacitidine.

      The study will enroll approximately 150 patients. Participants will be randomly assigned in
      1:1 ratio to one of the two treatment groups in 28-day treatment cycles and which will remain
      disclosed to the patient and study doctor during the study:

        -  Pevonedistat 20 mg/m^2 + Venetoclax 400 mg (ramp-up dose, Cycle 1 only: 100-400mg) +
           Azacitidine 75 mg/m^2

        -  Venetoclax 400 mg (ramp-up dose, Cycle 1 only: 100-400 mg) + Azacitidine 75 mg/m^2

      This multi-center trial will be conducted worldwide. The overall time to participate in this
      study is approximately 4 years. Participants will attend the end-of-treatment visit 30 days
      after the last dose of study drug or before the start of subsequent anti-neoplastic therapy
      if that occurs sooner. Participants who discontinue study treatment without evidence of
      progressive disease (PD) will enter EFS follow-up or response follow-up (study visits every 3
      months) or overall survival follow-up (contacted every 3 months to document subsequent
      therapies and survival status).
