Brief summary:
This is a phase II, open-label, multicenter, pilot study of the safety and efficacy of two Docetaxel-based regimens plus bevacizumab for the adjuvant treatment of participants with node positive or high risk node negative breast cancer.

The primary objective of this study was to evaluate the cardiac safety, and the secondary objectives were to evaluate safety and toxicity of participants treated with bevacizumab ± trastuzumab administered with 2 different docetaxel-based combination regimens.

This study was originally designed to also evaluate disease-free survival (DFS) and overall survival (OS); however, based on a protocol amendment, follow-up was shortened from 10 years to 2 years, and the efficacy endpoints of disease free survival and overall survival were deleted from the protocol.

Detailed description:

Arms:
arm 1: Human epidermal growth factor receptor-2 (HER2) negative participants stratified at registration, were administered chemotherapy with docetaxel, doxorubicin and cyclosphosphamide (TAC) + bevacizumab for Cycles 1-6 (every 3 weeks), and followed with maintenance therapy with bevacizumab every 3 weeks for a total of 52 weeks.

All participants were administered prophylactic recombinant Granulocyte Colony Stimulating Factor (G-CSF) during chemotherapy, based on a dose recommended by the manufacturer. For participants with estrogen receptor (ER) or progesterone receptor (PR) positive tumors, anti-estrogen therapy was recommended. Participants could receive radiation therapy at the discretion of the treating medical and radiation oncologist. arm 2: HER2 positive participants stratified at registration, were administered chemotherapy with docetaxel, carboplatin and trastuzumab (TCH) + bevacizumab for Cycles 1-6 (every 3 weeks), and followed with maintenance therapy with bevacizumab and trastuzumab every 3 weeks for a total of 52 weeks.

All participants were administered prophylactic recombinant Granulocyte Colony Stimulating Factor (G-CSF) during chemotherapy, based on a dose recommended by the manufacturer. For participants with estrogen receptor (ER) or progesterone receptor (PR) positive tumors, anti-estrogen therapy was recommended. Participants could receive radiation therapy at the discretion of the treating medical and radiation oncologist.

Interventions: intervention 1: Docetaxel intervention 2: Doxorubicin intervention 3: Carboplatin intervention 4: Cyclophosphamide intervention 5: Trastuzumab intervention 6: Bevacizumab
Intervention descriptions: intervention 1: 75 mg/m\^2 administered IV on Day 1 for Cycles 1-6

All participants received a prophylactic steroid regimen prior to each dose of docetaxel - Dexamethasone 8 mg orally 12 hours prior to docetaxel, dexamethasone 10 mg IV just prior the docetaxel infusion and 8 mg orally 12 hours after docetaxel administration. If a participant had not taken their oral dexamethasone the evening prior to receiving docetaxel, the dose of the pre-docetaxel infusion of dexamethasone was increased from 10 mg IV to 15 mg IV. A Dexamethasone 8 mg equivalent may have been used (dexamethasone 8 mg = methylprednisolone 40 mg = prednisone 50 mg = prednisolone 50 mg). intervention 2: 50 mg/m\^2 administered IV on Day 1 for Cycles 1-6 intervention 3: 6 mg/mL/min (target area under the curve \[AUC\] dose) administered IV on Day 1 for Cycles 1-6 intervention 4: 500 mg/m\^2 administered IV on Day 1 for Cycles 1-6 intervention 5: A single loading dose of 8 mg/kg administered IV on Day 2 for Cycle 1, and 6 mg/kg administered IV on Day 1 for Cycles 2-6 and for maintenance therapy intervention 6: 15 mg/kg administered IV on Day 1 for Cycles 1-6, and for maintenance therapy
