- Progression Free Survival [ Time Frame: Up to 31 months ]PFS is measured from randomization until the date of first documented disease progression or date of death from any cause, whichever comes first. Assessed for up to 31 months.
- Objective Response Rate [ Time Frame: Up to 31 months ]ORR is the proportion of subjects with measurable disease at baseline and who experience a best overall response of complete response (CR) or partial response (PR) which is confirmed ≥ 28 days later. Assessed for up to 31 months.
- Safety and tolerability of cabozantinib as assessed by adverse events. [ Time Frame: Up to 31 months ]Adverse events are measured from informed consent and at least through 30 days after the date of a decision to discontinue study treatment. Assessed for up to 31 months.
