Participant Flow

Study participants were planned to be assigned to 1 of 3 sequential dosing cohorts: CP-751,871 at 10 mg/kg; at 20 mg/kg; 2 doses of 20 mg/kg on consecutive days. Dosing was via intravenous (IV) administration. The third dosing cohort (2 doses of 20 mg/kg on consecutive days) did not enroll participants due to early termination of the study.
