primary Outcomes
  1. description
    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 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ at any time during the trial. Responses will be determined by independent central radiologic review, with confirmatory assessment as required per RECIST 1.1. Participants with unknown or missing response information will be treated as non-responders. The percentage of participants who experience a CR or PR based on modified RECIST 1.1 will be presented.
    measure
    Objective Response Rate (ORR)
    time Frame
    Up to approximately 10.5 years
secondary Outcomes
  1. description
    DOR, defined in the subset of participants with a CR or PR, based on RECIST 1.1 as assessed by independent central radiologic review, as the time from first documented evidence of CR or PR until the first documented sign of disease progression or death due to any cause, whichever occurs first. 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 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. Participants who are alive, have not progressed, have not initiated new anti-cancer treatment, and have not been determined to be lost to follow-up are considered ongoing responders at the time of analysis.
    measure
    Duration of Response (DOR)
    time Frame
    Up to approximately 10.5 years
  2. description
    PFS is defined as the time from allocation to the first documented disease progression according to RECIST 1.1 as assessed by independent central radiologic review, or death due to any cause, whichever occurs first. Per RECIST 1.1, progressive disease (PD) is defined as ≥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 ≥5 mm. Note: The appearance of one or more new lesions is also considered PD. If a participant does not have a documented date of progression or death, PFS will be censored at the date of the last adequate assessment.
    measure
    Progression Free Survival (PFS)
    time Frame
    Up to approximately 10.5 years
  3. description
    OS is defined as the time from randomization to death due to any cause. OS will be presented. Censoring will be performed using the date of last known contact for those who are alive at the time of analysis.
    measure
    Overall Survival (OS)
    time Frame
    Up to approximately 10.5 years
  4. description
    An adverse event (AE) is defined as any untoward medical occurrence in a study participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this intervention. The percentage of participants with AEs will be reported.
    measure
    Percentage of Participants with Adverse Events (AEs)
    time Frame
    Up to approximately 27 months
  5. description
    An AE is defined as any untoward medical occurrence in a study participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. The percentage of participants who discontinue study intervention due to AEs will be reported.
    measure
    Percentage of Participants who Discontinue Study Intervention due to AEs
    time Frame

Full study description
brief Summary
