- Median Overall Survival (OS) in Months at OS Data Cut Off (14th June 2010) [ Time Frame: Following the PFS DCO on 14th April 2008 information on survival status was collected every 8 weeks. ] [ Designated as safety issue: No ]
Overall Survival was assessed via calculation of the time to death due to any cause. If a participant was known to have died, the time to death was defined as the time from the date of randomization to the date of death. Otherwise, a participant was censored at the last date they were known to be alive. Median Overall Survival in months is presented here.
