About this study

The drug being tested in this study is called Pevonedistat. Pevonedistat is being tested to treat people with myelodysplastic syndromes MDS (including nonproliferative chronic myelomonocytic leukemia [CMML]) and AML (acute myeloid leukaemia) as a single-agent and in combination treatment with azacitidine. This study will look at the safety and tolerability, the recommended phase 2/phase 3 dose of pevonedistat administered in combination with azacitidine, pharmacokinetics and response to treatment in participants who take single agent pevonedistat compared to participants who take pevonedistat and azacitidine.

The study will enroll approximately 37 participants. Participants will be assigned into one of the four treatment groups which will remain disclosed to the patient and study doctor during the study. Participants will be first enrolled at single-agent low dose level (25 mg/m^2). If this dose is tolerable, participants will be enrolled in parallel at single-agent higher dose level (44 mg/m^2) and in combination treatment cohorts.

  • Pevonedistat 25 mg/m^2
  • Pevonedistat 44 mg/m^2
  • Pevonedistat 10 mg/m^2 and azacitidine 75 mg/m^2 combination
  • Pevonedistat 20 mg/m^2 and azacitidine 75 mg/m^2 combination Participants will receive pevonedistat infusion intravenously and azacitidine via intravenous or subcutaneous route.

This multi-center trial will be conducted in Japan, Korea and Taiwan. The overall time to participate in this study is approximately 24 months. Participants will attend the End of Study (EOS) visit for safety, 30 days after receiving their last dose of study drug or before the start of subsequent antineoplastic therapy (other than hydroxyurea).

Secondary outcomes

  1. Overall Response Rate (ORR) for Participants With AML

    Time frame: From first dose up to 30 days after last dose of study drug or before start of subsequent antineoplastic therapy, whichever comes earlier up to Cycle 19 (up to Day 429, single agent)(Cycle=21 days) and Cycle 65 (up to Day 1850, combination)(Cycle=28 days)

    ORR for AML was defined as the percentage of participants with a complete remission (CR), CR with incomplete blood count recovery (CRi), or partial remission (PR) based on Modified International Working Group (IWG) Response Criteria for AML. CR was defined as participant achieved the morphologic leukemia-free state and had an absolute neutrophil count (ANC) of more than 1,000 per microliter (/mcL) and platelets of greater than or equal to (>=) 100,000/mcL. A morphologic leukemia-free state requires less than (<) 5 percent (%) blasts in an aspirate sample with marrow spicules and with a count of at least 200 nucleated cells. CRi was, after chemotherapy, some participants who fulfilled all of the criteria for CR except for residual neutropenia (<1,000/mcL) or thrombocytopenia (<100,000/mcL). PR designation required all the hematologic values for a CR but with a decrease of at least 50% in the percentage of blasts to between 5% and 25% in the bone marrow aspirate.

  2. ORR for Participants With MDS

    Time frame: From first dose up to 30 days after last dose of study drug or before start of subsequent antineoplastic therapy, whichever comes earlier up to Cycle 19 (up to Day 429, single agent)(Cycle=21 days) and Cycle 65 (up to Day 1850, combination)(Cycle=28 days)

    ORR for MDS: Percentage of participants with CR,PR or hematologic improvement(HI) based on IWG Response Criteria. CR: BM:<=5% myeloblasts with normal maturation of all cell lines; persistent dysplasia noted peripheral blood: hemoglobin (Hgb)>=11 gram per deciliter (g/dL),platelets>=100*10^9/L,neutrophils >=1.0*10^9/L, blasts 0%. PR:CR criteria if abnormal before treatment except: BM blasts decreased by >=50% from pretreatment but still>5%; cellularity, morphology not relevant. HI criteria: Erythroid response:Hgb up by >=1.5 g/dL; transfused RBC reduced by at least 4 red blood cell (RBC) transfusions/8 weeks comparatively last 8 weeks; Platelet response: Increase of >=30*10^9/L for participants starting with >20*10^9/L platelets; increase from <20*10^9/L to >20*10^9/L and by 100%; Neutrophil response: At least 100% and absolute increase >0.5*10^9/L; Progression/relapse after HI: Granulocytes/platelets decreased by 50% from maximum; Hgb reduced by >=1.5 g/dL; transfusion dependence.

  3. Percentage of Participants With CR for Participants With AML

    Time frame: From first dose up to 30 days after last dose of study drug or before start of subsequent antineoplastic therapy, whichever comes earlier up to Cycle 19 (up to Day 429, single agent)(Cycle=21 days) and Cycle 65 (up to Day 1850, combination)(Cycle=28 days)

    CR was defined as participant achieved the morphologic leukemia-free state and had an ANC of more than 1,000/mcL and platelets of >=100,000/mcL. A morphologic leukemia-free state requires <5% blasts in an aspirate sample with marrow spicules and with a count of at least 200 nucleated cells. CR assessment was based on IWG Response Criteria.

  4. Percentage of Participants With CR for Participants With MDS

    Time frame: From first dose up to 30 days after last dose of study drug or before start of subsequent antineoplastic therapy, whichever comes earlier up to Cycle 19 (up to Day 429, single agent)(Cycle=21 days) and Cycle 65 (up to Day 1850, combination)(Cycle=28 days)

    CR was defined as participant with bone marrow: less than or equal to (<=) 5% myeloblasts with normal maturation of all cell lines; persistent dysplasia was noted peripheral blood: Hgb >=11 g/dL, platelets >=100*10^9/L, neutrophils >=1.0*10^9 per liter (/L), blasts 0%. CR assessment was based on IWG Response Criteria.
