Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: up to 24 months ]
    Objective Response Rate was defined as the percentage of participants with a complete response (CR) or partial response (PR)

Secondary Outcome Measures :
  1. Progression Free Survival (PFS) as Assessed by investigator [ Time Frame: up to 24 months ]
    Tumor response was assessed by investigator according to RECIST v1.1

  2. Overall Survival(OS) [ Time Frame: up to 24 months ]
    OS was defined as the time from the first study treatment to the date of death from any cause
