Study Endpoints
Primary Endpoints
Progression-free Survival (PFS) by Blinded Independent Central Review (BICR)

Time from randomisation until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomised therapy or receives another anti-cancer therapy prior to progression, based on BICR assessment according to RECIST v1.1

Secondary Endpoints
