Drug: Docetaxel
Docetaxel up to 75 mg/m^2 was administered intravenously [IV] on Day 1 of each 3-week dosing cycle.

Outcome Measure
Measure Description
Time Frame

Time Frame: 30 minutes predose at each cycle, End of Study (28 days after the last CP-751,871 infusion), and 150 days after the last CP-751,871 infusion
The development of HAHA is considered clinically relevant when temporally associated to the onset of adverse events or a significant decrease in the plasma concentrations of CP-751,871. The positive value is defined as ≥3.32.
30 minutes predose at each cycle, End of Study (28 days after the last CP-751,871 infusion), and 150 days after the last CP-751,871 infusion
Number of Participants With Objective Response (OR)
Time Frame: Baseline, every 2 months (approximately 7-10 days prior to the start of the next dose) up to Cycle 17 (1 cycle = 21 days)
Number of participants with OR based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST. Confirmed CR defined as disappearance of all target lesions. Confirmed PR defined as ≥30% decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat imaging study ≥4 weeks after initial documentation of response.

Time in weeks from start of study treatment to first documentation of objective tumor progression or death due to cancer, whichever comes first. TTP was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 7. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD])

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2005

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
