1.Primary Outcome
Title Objective Response Rate (ORR)
Hide Description ORR, defined as a complete response (CR) or partial response (PR) on two consecutive occasions >/=4 weeks apart, as determined by the investigator according to RECIST v1.1. CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR.
Time Frame From baseline until a total of 80 progression free survival (PFS) events have occurred (up to approximately 11 months)
Hide Outcome Measure Data
Hide Analysis Population Description
Intent-to-Treat (ITT) population included all participants randomized in the study.

5.Secondary Outcome
Title Percentage of Participants With Adverse Events
Hide Description An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Time Frame Up to 5 years
