Outcomes
Primary Outcomes
Progression-Free Survival (PFS)
Time Frame: Baseline, every 6 weeks until disease progression or death (up to 3 years from first dose)
Time in months from start of study treatment to first documentation of objective tumor progression (per RECIST) or death due to any cause. PFS was calculated as (first event date minus first randomization date plus 1) divided by 30.4. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease \[PD\]), or from adverse event (AE) data (where the outcome was "Death").
Secondary Outcomes
- Proportion of Participants With Objective Response(Baseline until response or disease progression (up to 3 years from first dose))
- Duration of Response (DR)(Time from first response to disease progression up to 3 years from first dose)
- Survival Probability at 1 Year(Baseline until death (up to 3 years after first dose of study medication))
- Overall Survival (OS)(Baseline until death (up to 3 years after first dose of study medication))
- Health Related Quality of Life (HRQoL) and Disease Related Symptoms as Measured by European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) Questionnaire (EORTC-QLQ-C30)(Day 1, Cycle 1; Day 1, odd number cycles; and end of treatment (EOT)/withdrawal)
- HRQoL and Disease Related Symptoms as Measured by EORTC-QLQ-C30 Breast Cancer Module (BR23) Score(Day 1, Cycle 1; Day 1, odd number cycles; and EOT/withdrawal)
- Observed Plasma Trough Concentrations (Ctrough) of Sunitinib(Predose Day 1, Cycles 1, 2, 3, 4, 5 and 7 and Day 15 of Cycles 1, 2, and 3)
- Ctrough of SU012662 (Metabolite of Sunitinib)(Predose Day 1, Cycles 1, 2, 3, 4, 5 and 7 and Day 15 of Cycles 1, 2, and 3)
- Ctrough of Total Drug (Sunitinib + SU012662)(Predose Day 1, Cycles 1, 2, 3, 4, 5 and 7 and Day 15 of Cycles 1, 2, and 3)
- Dose-corrected Ctrough of Sunitinib(Predose Day 1, Cycles 1, 2, 3, 4, 5 and 7 and Day 15 of Cycles 1, 2, and 3)

- Dose-corrected Ctrough of Total Drug (Sunitinib + SU012662)(Predose Day 1, Cycles 1, 2, 3, 4, 5 and 7 and Day 15 of Cycles 1, 2, and 3)
- Plasma Concentration of Soluble Vascular Endothelial Growth Factor Receptor 2 (sVEGFR2)(Baseline (Cycle 1, Day 1), Day 1 (Cycles 2, 3, 4, 5, and 7), and EOT/withdrawal)
- Plasma Concentration of Soluble Vascular Endothelial Growth Factor Receptor 3 (sVEGFR3)(Baseline (Cycle 1, Day 1), Day 1 (Cycles 2, 3, 4, 5, and 7), and EOT/withdrawal)
- Plasma Concentration of Soluble Vascular Endothelial Growth Factor A (sVEGF-A)(Baseline (Cycle 1, Day 1), Day 1 (Cycles 2, 3, 4, 5, and 7), and EOT/withdrawal)
