CP-751,871 was given intravenously \[IV\] every 3 weeks in escalating doses ranging from 0.1 mg/kg up to 20 mg/kg. Standard doses of Docetaxel were given every 3 weeks with CP-751,871. Study therapy was continued until disease progression, lack of tolerability for up to 17 cycles (approximately 1 year).
Docetaxel up to 75 mg/m\^2 was administered intravenously \[IV\] on Day 1 of each 3-week dosing cycle.
