Overall Survival (OS)
Lasso di tempo: Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)

Participants who were off treatment prior to Prog and who had no on-study disease assessment were also censored.
Prog: ≥20% increase in sum of longest dimension (LD) of target lesions from smallest sum LD recorded since treatment start or appearance of ≥1 new lesions.
