Conditions: Metastatic Breast Cancer
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 136
Healthy volunteers: no

Brief summary:
The purpose of this clinical research study is to learn if ixabepilone plus bevacizumab is effective in shrinking or stopping the growth of cancer when given as first-line chemotherapy in participants with metastatic breast cancer. The study will also assess the safety of this combination treatment.

Detailed description:

Arms:
arm 1: None arm 2: None arm 3: None

Interventions: intervention 1: Ixabepilone, 16 mg/m^2 + Bevacizumab, 10 mg/kg intervention 2: Ixabepilone, 40 mg/m^2 + Bevacizumab, 15 mg/kg intervention 3: Paclitaxel, 90 mg/m^2 + Bevacizumab, 10 mg/kg
Intervention descriptions: intervention 1: Ixabepilone,16 mg/m\^2, administered as a 1-hour intravenous (IV) infusion on Days 1, 8, and 15 of a 28-day cycle until disease progression or unacceptable toxicity. Bevacizumab, 10 mg/kg, administered as IV infusion every 2 weeks. Bevacizumab to be infused over 90 minutes for the first dose, and if well tolerated for 60 minutes, for the second dose. Then if still tolerated, over 30 minutes for subsequent infusions. Bevacizumab was to be dosed until disease progression or unacceptable toxicity. intervention 2: Ixabepilone, 40 mg/m\^2, administered as a 3-hour IV infusion on Day 1 of a 21-day cycle until disease progression or unacceptable toxicity (After Cycle 4, dose reduction to 32 mg/m\^2 was to be implemented for all subsequent cycles.) Bevacizumab, 15 mg/kg, administered as IV infusion every 3 weeks. Bevacizumab to be infused over 90 minutes for the first dose, and if well tolerated for 60 minutes, for the second dose. Then if still tolerated, over 30 minutes for subsequent infusions. Bevacizumab was to be dosed until disease progression or unacceptable toxicity. intervention 3: Paclitaxel, 90 mg/m\^2, given as a 1-hour IV infusion on Days 1, 8, and 15 of a 28-day cycle until disease progression or unacceptable toxicity. Bevacizumab, 10 mg/kg, administered as IV infusion every 2 weeks. Bevacizumab infused over 90 minutes for the first dose, and if well tolerated, over 60 minutes for the second dose. If still tolerated, over 30 minutes for subsequent infusions. Bevacizumab was to be dosed until disease progression or unacceptable toxicity.
