Trial outcomes
Primary outcomes
Progression free survival (PFS)
PFS is defined as the time from randomization until disease progression or death from any cause, whichever occurs first. Progression is assessed per response evaluation criteria in solid tumors (RECIST) v1.1 by blinded independent central review (BICR).
Secondary outcomes
Overall survival (OS)
OS is defined as the time from randomization until death from any cause.
Objective response rate (ORR)
Objective response is defined as partial response (PR) or complete response (CR) as assessed per RECIST v1.1 by BICR.
Duration of response (DOR)
DOR is defined as time from first evidence of objective response (PR or CR) to disease progression or death due to any cause, whichever occurs first. Response and progression are per RECIST v1.1, as assessed by BICR.
Incidence of adverse events (AEs)
Percentage of patients with AEs as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v5
