Reporting Groups

	Description
Figitumumab 20 mg/kg	Figitumumab (CP-751,871) was given in 3-week cycles for a total of up to 17 cycles. Participants can receive treatment beyond 17 cycles provided clinical benefit is being achieved. Figitumumab 20 milligram/kilogram (mg/kg) was administered as an intravenous (IV) infusion on Day 1 and 2 in Cycle 1 (loading dose), and on Day 1 of every cycle thereafter.
Figitumumab 30 mg/kg	Figitumumab (CP-751,871) was given in 3-week cycles for a total of up to 17 cycles. Participants can receive treatment beyond 17 cycles provided clinical benefit is being achieved. Figitumumab 30 milligram/kilogram (mg/kg) was administered as an IV infusion on Day 1 and 2 in Cycle 1 (loading dose), and on Day 1 of every cycle thereafter.
