Primary Outcome Measures :
  1. Objective Response Rate (ORR) as Assessed by Blinded Independent Central Review (BICR) [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    ORR is defined as the proportion of participants with a best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR) as assessed by BICR per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.


Secondary Outcome Measures :
  1. Duration of Response (DoR) [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    DoR is defined as the time from the first documented confirmed response (CR or PR) to the date of progression or death due to any cause as assessed by BICR and Investigator per RECIST v1.1, respectively.

  2. Progression-free Survival (PFS) [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    PFS is defined as the time from the start of study treatment to the earlier of the dates of the first documentation of objective progressive disease (PD) per RECIST v1.1 or death due to any cause. PFS will be determined by BICR and by Investigator, respectively.

  3. Objective Response Rate (ORR) as Assessed by the Investigator [ Time Frame: Data collected from screening until time of disease progression, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    ORR is defined as the proportion of participants with a BOR of confirmed CR or confirmed PR as assessed by the Investigator per RECIST v1.1.

  4. Disease Control Rate (DCR) [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    DCR is defined as the proportion of participants who achieved a BOR of confirmed CR, confirmed PR, or stable disease (SD) as assessed by BICR and by the Investigator per RECIST v1.1, respectively.

  5. Time to Tumor Response (TTR) [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    TTR is defined as the time from the start of study treatment to the date of the first documentation of confirmed response (CR or PR) as assessed by BICR and Investigator per RECIST v1.1, respectively.

  6. Best percentage change in the sum of diameters (SoD) of measurable tumors [ Time Frame: Data collected from screening until time of disease progression by BICR, death, lost to follow up, study discontinuation, whichever occurs first, assessed up to approximately 26 months ]
    The best percentage change in the SoD of measurable tumors is defined as the percentage change in the smallest SoD from all post-baseline tumor assessments, taking as reference the baseline SoD.

  7. Overall Survival (OS) [ Time Frame: Death date is collected until the participant discontinues the study or up to approximately 26 months ]
    OS defined as the time from the start of study treatment to the date of death due to any cause.

  8. Incidence of treatment emergent adverse events (TEAEs), serious adverse events (SAEs), and adverse events of special interest (AESIs) [ Time Frame: From baseline up to Day 47 post last dose ]
    A TEAE is defined as an adverse event (AE) with a start or worsening date during the on-treatment period. A serious AE is defined as any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is an important medical event, or may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes noted. AESIs will also be assessed. Adverse events will be coded using MedDRA and will be graded using NCI-CTCAE v5.0.
