Primary Outcome Measures:
  • Endpoint of Overall survival (OS) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    OS is defined as the time between the date of randomization and the date of death. For subjects without documentation of death, OS will be censored on the last date the subject was known to be alive

Secondary Outcome Measures:
  • Progression-free survival (PFS) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    PFS is defined as the time from randomization to the date of the first documented progression, as determined by the investigator, or death due to any cause, whichever occurs first

  • Objective Response Rate (ORR) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    ORR is defined as the number of subjects with a Best Overall Response (BOR) of Complete Response (CR) or Partial response (PR) divided by the number of randomized subjects for each treatment arm

  • Programmed death-ligand 1 (PD-L1) expression as predictive biomarker [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    PD-L1 expression as measured by the endpoint OS based on PD-L1 expression level

  • Health Related Quality of Life (HRQoL) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]

    HRQoL as measured by mean changes from baseline in the EORTC-QLQ-C30 global health status/QoL composite scale and by mean changes from baseline in the remaining EORTC QLQ-C30 scales in all randomized subjects;

    EORTC-QLQ-C30 = European Organisation for Research and Treatment of Cancer - Quality of Life Questionnaire - Core 30

Estimated Enrollment: 410
Study Start Date: January 2013
Estimated Study Completion Date: November 2016
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
