Study Endpoints
Primary Endpoints
Progression-Free Survival (PFS)
Treatment period consisted of 4-week cycles with radiologic tumor assessment every 12 weeks from date of randomization until date of first documented PD or date of death from any cause, whichever came first, assessed up to 34 months.

The duration of Progression-Free Survival (PFS) using progression events as determined by Independent Review Committee (IRC) per mRECIST, or death due to any cause. The analysis was conducted after at least 315 subjects were randomized and at least 138 events were observed.

Secondary Endpoints
Overall Survival (OS) With XL184 Compared With Placebo
The pre-specified interim analysis of Overall Survival (OS) was assessed at 44% of required events. Includes data up to 15June2011. As of this date, the number of deaths required to conduct the primary analysis had not been reached.
Objective Response Rate (ORR)
Assessed at the same time as primary analysis of Progression Free Survival (PFS) data. Assessed at baseline and every 12 weeks until Progressive Disease (PD) up to 34 months.
Duration of Objective Response (OR): Independent Radiology Committee (IRC) Determined
From time of first documentation of Objective Response (OR), confirmed at a later visit ≥28 days later as Progressive Disease (PD) as defined by mRECIST or death due to any cause, assessed up to 34 months.
