What was measured

Time to AML transformation in HR MDS and CMML participants is defined as time from randomization to documented AML transformation. Participants without documented AML transformation at the time of the analysis are censored at the date of the last assessment. Participants who died before progression to AML are censored at the date of death. Transformation to AML is defined, according to World Health Organization (WHO) classification, as a participant having \>20% blasts in the blood or marrow and increase of blast count by 50%.

Analysis population: ITT Population was defined as all participants who were randomized. Overall number of participants analyzed is the number of participants with data available for analyses.

Groups in this outcome

Azacitidine 75 mg/m^2

Azacitidine 75 mg/m\^2, infusion, intravenously or subcutaneously, on Day 1 through Day 5, Days 8 and 9 in 28-day treatment cycles until unacceptable toxicity, relapse, transformation to AML (for participants with HR MDS or CMML), or progressive disease (for participants with low-blast AML).

Azacitidine 75 mg/m^2 + Pevonedistat 20 mg/m^2

Azacitidine 75 mg/m\^2, infusion, intravenously or subcutaneously, on Day 1 through Day 5, Days 8 and 9 and pevonedistat 20 mg/m\^2, infusion, intravenously, on Days 1, 3, and 5 in 28-day treatment cycles until unacceptable toxicity, relapse, transformation to AML (for participants with HR MDS or CMML), or progressive disease (for participants with low-blast AML).
