Overall Survival (OS) |
OS was defined as the time from the date of randomization to the date of death due to any cause. Participants without documented death at the time of the analysis were censored at the date the participant was last known to be alive. The Kaplan Meier estimates was used for the analysis. |

Event-Free Survival (EFS) |
EFS is defined as the time from the date of randomization to the date of the occurrence of an event. An event is defined as death or transformation to AML for HR MDS/CMML participants, whichever occurs first, or defined as death for low-blast AML participants. HR MDS/CMML participants without documented EFS event will be censored at the date of the last response assessment. HR MDS/CMML participants with no response assessment and no death will be censored at the date of randomization. Low-blast AML participants without documentation of death will be censored at the date the participant was last known to be alive. HR MDS/CMML participants who received alternative antineoplastic therapy before death or transformation to AML will be censored at the date of last adequate assessment prior to starting alternate antineoplastic therapy. The Kaplan-Meier estimate was used for the analysis. |

Time to AML Transformation in HR MDS or CMML Participants |
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%. |
