Primary

MeasureTime frameDescription
Progression Free Survival (PFS)From randomization to date of first documented tumor progression or death (up to approximately 33 months)Progression Free Survival (PFS) is defined as the time between the date of randomization and the date of first documented tumor progression, assessed by a blinded independent central review (BICR) (per RECIST v1.1 criteria), or death due to any cause, whichever occurs first. Subjects who die without a reported progression will be considered to have progressed on the date of their death.

Secondary

MeasureTime frameDescription
Overall Response Rate (ORR)From randomization up to approximately 3 yearsObjective response rate (ORR) is defined as the number of randomized subjects who achieve a best response of complete response (CR) or partial response (PR) based on BICR assessments (using RECIST v1.1 criteria).
Overall Survival (OS)From randomization to the date of death (up to approximately 3 years)Overall Survival (OS) is defined as the time between the date of randomization and the date of death due to any cause. For subjects that are alive, their survival time will be censored at the date of last contact (last known alive date).
