Study Endpoints
Primary Endpoints
Progression Free Survival (PFS) determined by blinded independent central review (BICR)
Until progression or death, assessed up to approximately 4 years

PFS is defined as the time from randomization to the first occurrence of disease progression as determined by BICR using RECIST v1.1, or death from any cause, whichever occurs first.

Confirmed overall response rate (ORR) as determined by BICR
Until progression or death, assessed up to approximately 3 years

Confirmed ORR is defined as the percentage of participants with a confirmed CR or PR based on BICR assessment relative to the total number of participants.

Secondary Endpoints
Overall survival (OS)
Until death, assessed up to approximately 5 years
Investigator-assessed PFS
Until progression or death, assessed up to approximately 4 years
Investigator-assessed confirmed ORR
Until progression or death, assessed up to approximately 3 years
