Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: 30 months ]

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 Lung Cancer Symptom Scale (LCSS).

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