What was measured

OS was defined as the time interval from the date of randomization to the date of death due to any cause. In the absence of confirmation of death, survival time was censored at the last date participant was known to be alive, or at the cut-off date if the participant's last contact was after the cut-off date. The study cut-off date for the final analysis of OS was the date when the 774th death had been observed. Analysis was performed by Kaplan-Meier method.

Analysis population: ITT population included all randomized participants.

    group Description
    Hazard ratio was estimated using a Cox Proportional Hazards regression model. The Cox proportional hazard model was adjusted by Eastern Cooperative Oncology Group performance status (ECOG PS) score at baseline, measurable disease at baseline, and region with commercial availability of cabazitaxel at the time of randomization.
