Treatment groups
Trial outcomes
Primary outcomes
Overall survival (OS)
Overall survival (OS) is defined as the time between the subject's randomization date and subject's death.
Secondary outcomes
Progression-free survival (PFS)
Progression-free survival (PFS) as assessed by BICR is defined as the time between the date subjects were randomized and the first observation of disease progression (based on BICR's image-based assessment) or death.
Objective Response Rate (ORR)
Objective response rate (ORR) is defined as the number of CR and PR in the treatment and control groups divided by the number of that group in the full analysis set (FAS).
Disease Control Rate (DCR)
Disease Control Rate (DCR) : Percentage of all randomized subjects who rated the best overall response (BOR) as complete response (CR), partial response (PR), and disease stabilization (SD) according to RECIST 1.1 criteria.
Duration of Response (DOR)
Duration of Response (DOR) : defined as the period from the date when tumor response is first recorded to the date when objective tumor progression is first recorded or the date of death.
