What was measured

Overall survival is defined as the time from randomization until death. In the event that no death was documented prior to study termination or analysis cutoff, OS was censored at the last known date the subject was known to be alive, either through completion of on-study visits or through survival follow-up contact. The treatment effect on OS was evaluated using the stratified log-rank test (stratified by tumor histology). The Kaplan-Meier curves were also plotted. A Cox proportional hazard model with an adjustment for tumor histology (biphasic vs sarcomatoid) was used to compute the estimated hazard ratio and two-sided 95% CI. The treatment effect on OS was evaluated using the stratified log-rank test (stratified by tumor histology). The significance level to be used in the OS analysis at the final analysis was based on α = 0.04999 (two-sided).
