Primary Outcome Measures:
- Percentage of Participants With Prostate Specific Antigen (PSA) Response [ Time Frame: Baseline, Day 1 of each 21-day cycle ] [ Designated as safety issue: No ]PSA response rate, which is defined as a greater than or equal to a 50% decrease in PSA from baseline, that is subsequently confirmed.
Secondary Outcome Measures:
- Time to PSA Progression [ Time Frame: Baseline to first documentation of PSA progression up to 28 days after date of last dose ] [ Designated as safety issue: No ]Defined as the time from start of study treatment to first documentation of PSA progression using the PSA Working Group criteria calculated as (first event date - first dose date + 1)/7. PSA progression is defined for patients with a PSA response, as a 50% increase over nadir (lowest) and increase in absolute-value PSA level by at least 5 nanograms per milliliter (ng/mL) [or back to baseline] and for patients without a PSA response as a 25% increase over baseline [or nadir (lowest)] and increase in absolute-value PSA level by at least 5 ng/mL, both confirmed by a second value.
- Duration of PSA Response (DPR) [ Time Frame: Baseline to first documentation of PSA progression up to 28 days after date of last dose ] [ Designated as safety issue: No ]Defined as time from first documentation of PSA response (≥50% decrease in PSA from baseline that is subsequently confirmed) to first documentation of PSA progression (defined for patients with a PSA response as a 50% increase over nadir [lowest] and increase in absolute-value PSA level by at least 5 ng/mL [or back to baseline] and for patients without a PSA response as a 25% increase over baseline [or nadir / lowest] and increase in absolute-value PSA level by at least 5 ng/mL, both confirmed by a second value). Calculated as (end date for DPR - first PSA response + 1)/7.
- Percentage of Participants With Objective Response Rate (ORR) [ Time Frame: Baseline to first documentation of PSA progression up to 28 days after date of last dose ] [ Designated as safety issue: No ]Defined as confirmed complete response (CR: disappearance of all target lesions) or confirmed partial response (PR: ≥30% decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD) according to response evaluation criteria in solid tumors (RECIST). Confirmed responses are those that persist on repeat imaging study ≥4 weeks after initial documentation of response.
- Ratio to Baseline (Bsl) in Median Levels of Soluble Protein Biomarkers by Prostate Specific Antigen (PSA) Response: VEGFC [ Time Frame: Baseline (Cycle 1 Day 1 [C1.D1]), C1.D14, C2.D1, C2.D14, C3.D1, C3.D14 ] [ Designated as safety issue: No ]Soluble protein biomarker Vascular Endothelial Growth Factor C (VEGFC) measured as picograms per milliliter (pg/mL). PSA responders are participants with a confirmed PSA response as per the Working Group criteria (>50% decrease from baseline) and non-responders are those not meeting the definition of responder. Ratio=value of soluble protein biomarkers at each time point to the value at baseline (C1D14 : C1D1).
- Ratio to Baseline in Median Levels of Soluble Protein Biomarkers by Prostate Specific Antigen (PSA) Response: VEGFR2 [ Time Frame: Baseline (C1.D1), C1.D14, C2.D1, C2.D14, C3.D1, C3.D14 ] [ Designated as safety issue: No ]Soluble protein biomarker Vascular Endothelial Growth Factor receptor 2 (VEGFR2) measured as pg/mL. PSA responders are participants with a confirmed PSA response as per the Working Group criteria (>50% decrease from baseline) and non-responders are those not meeting the definition of responder. Ratio=value of soluble protein biomarkers at each time point to the value at baseline (C1D14 : C1D1).
- Ratio to Baseline in Median Levels of Soluble Protein Biomarkers by Prostate Specific Antigen (PSA) Response: VEGFR3 [ Time Frame: Baseline (C1.D1), C1.D14, C2.D1, C2.D14, C3.D1, C3.D14 ] [ Designated as safety issue: No ]Soluble protein biomarker Vascular Endothelial Growth Factor Receptor 3 (VEGFR3) measured as picograms per milliliter (pg/mL). PSA responders are participants with a confirmed PSA response as per the Working Group criteria (>50% decrease from baseline) and non-responders are those not meeting the definition of responder. Ratio=value of soluble protein biomarkers at each time point to the value at baseline (C1D14 : C1D1).
- Ratio to Baseline in Median Levels of Soluble Protein Biomarkers by Clinical Benefit Response (CBR): VEGFC [ Time Frame: Baseline (C1.D1), C1.D14, C2.D1, C2.D14, C3.D14 ] [ Designated as safety issue: No ]Soluble protein biomarker VEGFC measured as pg/mL. CBR defined as confirmed CR (disappearance of all target lesions) or confirmed PR (≥30% decrease in sum of longest dimensions [LD] of target lesions taking as reference the baseline sum LD) or SD (neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease) ≥3 months versus PD (≥20% increase in sum LD of target lesions taking as reference the smallest sum LD recorded since treatment started, unequivocal progression of existing non-target lesions, or appearance of ≥1 new lesions) or SD <3 months.

- Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-sf) : Pain Intensity (Questions 2-5) [ Time Frame: Baseline (C1.D1), Day 1 of Cycles 2 through 16, and End of Treatment (EOT=following Cycle 16 or within 7 days of withdrawal from study) ] [ Designated as safety issue: No ]The questionnaire assesses pain intensity (worst, least, average, and right now), level of relief in the last 24 hours, and the impact of pain on daily functions (general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life). The pain intensity index score was derived from Questions 2-5 with range from 0 to 10 (0: no pain; 1-4: mild pain; 5-6: moderate pain; 7-10: severe pain); higher scores indicate worse health status.
- Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-sf): Pain Interference (Questions 7A Through 7G) [ Time Frame: Baseline (C1.D1), Day 1 of Cycles 2 through 16, and End of Treatment (EOT=following Cycle 16 or within 7 days of withdrawal from study) ] [ Designated as safety issue: No ]The questionnaire assesses pain intensity (worst, least, average, and right now), level of relief in the last 24 hours, and the impact of pain on daily functions (general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life). The pain interference index score (to measure how much pain had interfered with daily activities) was derived from Questions 7A-7G with a range from 0 (no interference) to 10 (completely interferes); higher scores indicate more interference.
- Change From Baseline in Functional Assessment of Cancer Therapy-Prostate (FACT-P) Questionnaire (FACT-General and Prostate Cancer Subscale) [ Time Frame: Baseline (C1.D1), Day 1 of Cycles 2 through 16, and End of Treatment (EOT=following Cycle 16 or within 7 days of withdrawal from study) ] [ Designated as safety issue: No ]Assesses health related quality of life and advanced prostate cancer specific symptoms. FACT-General (FACT-G) assesses 4 domains: physical, social and family, emotional, and functional well-being. The prostate cancer subscale assesses prostate cancer symptoms focusing on pain, urination problems, and sexual functions. Individual scores range from 0 (not at all) to 4 (very much). Scores for some of the individual questions are reverse-coded in order for higher scores to correspond to better health status. FACT-P overall score range is 0 to 156; higher scores indicate better health status.
- Preliminary Assessment of PSA Modulation by SU011248 [ Time Frame: Baseline to Day 28 ] [ Designated as safety issue: No ]PSA modulation analyzed by the mean change in PSA response measured as ng/mL.
