- Progression Free Survival (PFS) [ Time Frame: From randomization to date of first documented tumor progression or death (up to approximately 33 months) ]Progression Free Survival (PFS) is defined as the time between the date of randomization and the date of first documented tumor progression, assessed by a blinded independent central review (BICR) (per RECIST v1.1 criteria), or death due to any cause, whichever occurs first. Subjects who die without a reported progression will be considered to have progressed on the date of their death.
- Overall Survival (OS) [ Time Frame: From randomization to the date of death (up to approximately 3 years) ]Overall Survival (OS) is defined as the time between the date of randomization and the date of death due to any cause. For subjects that are alive, their survival time will be censored at the date of last contact ("last known alive date").
- Overall Response Rate (ORR) [ Time Frame: From randomization up to approximately 3 years ]Objective response rate (ORR) is defined as the number of randomized subjects who achieve a best response of complete response (CR) or partial response (PR) based on BICR assessments (using RECIST v1.1 criteria).
- The Number of Participants Experiencing Adverse Events (AEs) [ Time Frame: From first dose to 30 days after last dose of study therapy (up to approximately 33 months) ]
The number of participants experiencing adverse events (AEs).
An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment.
- The Number of Participants Experiencing Serious Adverse Events (SAEs) [ Time Frame: From first dose to 30 days after last dose of study therapy (up to approximately 33 months) ]
The number of participants experiencing serious adverse events (SAEs).
A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose: Results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is an important medical event.
- The Number of Participants Experiencing Adverse Events (AEs) Leading to Discontinuation [ Time Frame: From first dose to 30 days after last dose of study therapy (up to approximately 33 months) ]
The number of participants experiencing adverse events (AEs) leading to discontinuation.
An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment.
- The Number of Participant Deaths in the Study [ Time Frame: From first dose up to approximately 33 months ]The number of participant deaths in the study.
- The Number of Participants Experiencing Laboratory Abnormalities in Specific Liver Tests [ Time Frame: From first dose to 30 days after last dose of study therapy (up to approximately 33 months) ]The number of participants with clinical laboratory test abnormalities in specific liver tests based on US conventional units.
- The Number of Participants Experiencing Laboratory Abnormalities in Specific Thyroid Tests [ Time Frame: From first dose to 30 days after last dose of study therapy (up to approximately 33 months) ]The number of participants with clinical laboratory test abnormalities in specific thyroid tests based on US conventional units.
