End point description |
Dose-limiting hematological and non-hematological toxicities were defined differently. All Grade 3 or greater non-hematological toxicity not clearly related to the underlying disease and attributable to protocol therapy will be considered a DLT. Hematological DLT attributable to protocol therapy was defined as failure to recover to a peripheral absolute neutrophil count (ANC) > 500 per meter cube (/m^3) and platelets > 20,000 per millimeter square (/mm^2) by 50 days from the start of fludarabine and cytarabine administration, not due to presence of leukemia or severe infection. DLT Analysis Set included all participants who must receive at least 85% of the prescribed dose per protocol guidelines and must have the appropriate toxicity monitoring studies performed to be considered evaluable for dose limiting toxicity.

blasts or extramedullary disease and with recovery of ANC > 1000/uL and platelet
transfusion independence (defined as no platelet transfusions x 1 week). Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment.

CR was defined by National Cancer Institue (NCI) Common Terminology
Criteria for Adverse Events (CTCAE) Version 5.0 as attainment of an M1 bone marrow (< 5% blasts and adequate marrow cellularity) with no evidence of circulating blasts or extramedullary disease and with recovery of peripheral blood counts (ANC >= 1000 per microliter [/uL] and platelet count > 100,000/uL). Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment.

Percentage of Participants With Partial Response (PR) | ||||||||
End point description |
PR was defined by NCI CTCAE Version 5.0 as attainment of M2 marrow status (> 5% or < 25% blasts cells and adequate
cellularity) and at least 50% decrease in bone marrow blast percent from baseline.
Bone marrow must have adequate cellularity (e.g. > 10% if a biopsy is performed)
to determine response. A repeat bone marrow aspiration within 14 days may be required
to distinguish between a PR and increased blasts caused by bone marrow
regeneration, and is left to the discretion of the investigator. Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment.

Percentage of Participants With Overall Complete Remission Rate | ||||||||
End point description |
Overall complete remission rate was defined as percentage of participants with CR, CRp and CRi.CR was defined as attainment of an M1 bone marrow (<5% blasts and adequate marrow cellularity) with no evidence of circulating blasts or extramedullary disease and with recovery of peripheral blood counts (ANC>=1000/uL and platelet count >100,000/uL).CRp was defined as attainment of an M1 bone marrow (<5% blasts) and no evidence of circulating blasts or extramedullary disease and with recovery of ANC >1000/uL and platelet transfusion independence.CRi was defined as attainment of an M1 bone marrow (<5% blasts) and no evidence of circulating blasts or extramedullary disease and with ANC < 1000/uL or platelet count < 100,000/uL without platelet transfusion independence.Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment.

Percentage of Participants With Treatment Failure (TF) | ||||||||
End point description |
TF was defined by NCI CTCAE Version 5.0 as 1. An increase in the extent of bone marrow infiltration by leukemic cells (absolute increase of >= 20% blasts). 2. Development of extramedullary disease (EMD). 3. M2 marrow that does not qualify for PR status. 4. An M1 marrow with circulating blasts. 5. > 25% blasts in the bone marrow after Cycle 1 of therapy. 6. Participants who have persistent central nervous system (CNS) disease despite 6 doses of intrathecal (IT) cytarabine or IT triples. Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment.

Duration of Complete Response | ||||||||
End point description |
Duration of disease response in months is defined as the time measured in months, from the date of first documented disease response to the date of first documentation of relapse or progression. For participant without
relapse or disease progression, duration of disease was censored at the last disease assessment date. Response-Evaluable Analysis Set included all participants who receive at least one dose of Pevonedistat, have a baseline disease assessment, and have at least one post-baseline disease assessment. 9999 = Median and full range of duration of complete response was not estimable due to fewer number of participants with events.
