Secondary Outcome Measures :
  1. Duration of Response (DOR) as Assessed by IRC [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    DOR - defined as the time from the first determination of a confirmed objective response by IRC according to RECIST version 1.1 until the first documentation of progression or death, whichever comes first

  2. Progression-Free Survival (PFS) as Assessed by IRC [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    PFS is defined as the time from the date of first dose of study drug to the date of first documentation of disease progression assessed by IRC using RECIST version 1.1 or death, whichever occurs first

  3. Disease Control Rate (DCR) as Assessed by IRC [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    DCR is defined as the percentage of participants who achieve CR, PR and stable disease (SD) assessed by IRC using RECIST version 1.1

  4. Overall Survival (OS) [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    OS - defined as the time from the date of first dose of study drug until the date of death from any cause

  5. ORR as Assessed by the Investigators [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    ORR is defined as the percentage of participants who had confirmed complete response (CR) or partial response (PR) as assessed by the investigators per RECIST version 1.1 and immune related RECIST (irRECIST)

  6. DOR as Assessed by Investigators Per RECIST Version 1.1 and irRECIST [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    DOR is defined as the time from the first determination of a confirmed objective response by the investigator according to RECIST version 1.1 and irRECIST until the first documentation of progression or death, whichever comes first

  7. PFS as Assessed by Investigators Per RECIST Version 1.1 and irRECIST [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    PFS is defined as the time from the date of first dose of study drug to the date of first documentation of disease progression assessed by the investigator according to RECIST version 1.1 and irRECIST until the first documentation of progression or death, whichever comes first

  8. DCR as Assessed by Investigators Per RECIST Version 1.1 and irRECIST [ Time Frame: From the date of first dose up to approximately 2 years and 2 months ]
    DCR is defined as the percentage of participants who achieve CR, PR and stable disease (SD) assessed by investigators per RECIST version 1.1 and irRECIST

  9. Number of Participants Experiencing Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: From the date of first dose until End of Study (approximately 3 years and 9 months) ]
    TEAE is defined as an adverse event (AE) that had an onset date or a worsening in severity from baseline pre-treatment) on or after the first dose of study drug up to 30 days following study drug .discontinuation. An SAE is any untoward medical occurrence that, at any dose that results in death or is life-threatening.
