Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: 30 months ]
    Defined as time from date of randomization to date of death due to any cause.

  2. Progression-free Survival (PFS) [ Time Frame: 30 months ]
    Defined as time from randomization until disease progression or death from any cause, whichever occurs first.


Secondary Outcome Measures :
  1. Adverse Events [ Time Frame: 30 months ]
    Defined as number of patients with treatment emergent AEs.

  2. Objective Response Rate (ORR) [ Time Frame: 30 months ]
    Defined as the percent of patients documented to have a confirmed CR or PR.

  3. Duration of Response (DOR) [ Time Frame: 30 months ]
    Defined as the time from date of the first documentation of objective tumor response (CR or PR) to the first documentation of either Progression of Disease (PD) or death due to any cause, whichever occurs first.

  4. Patient Reported Outcomes (PROs) [ Time Frame: 30 months ]
    To be assessed by European Quality of Life Questionnaire for Cancer Patients (QLQ-C30).

  5. Quality of Life Assessment [ Time Frame: 30 months ]
    To be assessed by European Quality of Life Five Dimensions Questionnaire (EQ-5D-5L).
