  Outcome Measures

1.  Primary:   Overall Survival (OS)   [ Time Frame: Baseline of Phase 2 to death or until at least 1 year after the randomization of the last participant ]
  Hide Outcome Measure 1

Measure Type Primary
Measure Title Overall Survival (OS)
Measure Description Time in days from randomization to date of death due to any cause. OS was calculated as the death date minus the the date of randomization plus 1. Death was determined from adverse event data (where outcome was death) or from follow-up contact data (where the participant current status was death).
Time Frame Baseline of Phase 2 to death or until at least 1 year after the randomization of the last participant  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Phase 2 intent to treat (ITT) population included all participants randomized with study drug assignment designated according to initial randomization, regardless of whether participants received study drug or a drug different from that to which they were randomized.

[1] Additional details about the analysis, such as null hypothesis and power calculation:
  Differences in OS between treatment arms was analyzed by the stratified log-rank test where the stratification factors are Eastern Cooperative Oncology Group (ECOG) performance status (less than or equal to 1 or 2) and extent of disease (locally advanced or metastatic).
