Outcomes

Primary Outcome Measures

Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by Blinded Independent Central Review (BICR)
ORR is defined as the percentage of participants who have a Complete Response (CR: disappearance of all target lesions) or a Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. ORR as assessed by BICR will be presented.

Secondary Outcome Measures

Duration of Response (DOR) per RECIST 1.1 as assessed by BICR
DOR is defined as the time from the first documented evidence of a CR (disappearance of all target lesions) or a PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 until Progressive Disease (PD) or death due to any cause, whichever occurs first, in participants demonstrating a CR or PR. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.
Progression-Free Survival (PFS) per RECIST 1.1 as assessed by BICR
PFS is defined as the time from randomization (or first dose) to the first documented PD per RECIST 1.1 or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR will be presented.
PFS per RECIST 1.1 as assessed by Investigator
PFS is defined as the time from randomization (or first dose) to the first documented PD per RECIST 1.1 or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by investigator will be presented.
ORR per RECIST 1.1 as assessed by Investigator
ORR is defined as the percentage of participants who have a CR (disappearance of all target lesions) or a PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. ORR as assessed by investigator will be presented.
DOR per RECIST 1.1 as assessed by Investigator

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study intervention. The number of participants with an AE will be presented.
Number of Participants Discontinuing Study Treatment Due to an AE
