Summary
Pilot, phase II, parallel-group, open-label, noncomparative, prospective, multicenter study designed to evaluate the progression-free survival of docetaxel and bevacizumab ± trastuzumab for the first-line treatment of participants with metastatic breast cancer. Participants were stratified according to human epidermal growth factor receptor-2 (HER2) status at the time of enrollment. HER2 negative participants were assigned to receive docetaxel and bevacizumab (DB). HER2 positive participants were assigned to receive docetaxel, bevacizumab, and trastuzumab (DBT).
All participants (except one) were off study treatment on 30 June 2011. All efficacy analysis and safety analysis was performed using the cut-off date of June 2011. One participant continued treatment till 11 March 2012. For this participant, adverse events were collected upto 19 April 2012 and included in the safety analysis.

Eligibility Criteria
The following information on clinical trials is provided for information purposes only to allow participants and physicians to have an initial discussion about the trial. This information is not intended to be complete information about the trial, to contain all considerations that may be relevant to potential participation in the trial, or to replace the advice of a personal physician or health professional.
INCLUSION CRITERIA
- Histologically or cytologically proven adenocarcinoma of the breast at first diagnosis
- Stage IV disease with at least one measurable lesion according to the RECIST criteria
- HER2/neu positive as determined by 3+ immunohistochemistry (IHC) staining or fluorescence in situ hybridization (FISH) positivity or negative tumors
- Life expectancy of >/= 24 weeks
- No prior chemotherapy for metastatic breast cancer. (Prior endocrine therapy is permitted).
- Prior neoadjuvant or adjuvant chemotherapy is permitted, or at least 12 months must have elapsed since the neoadjuvant or adjuvant therapy. Subjects may have received prior adjuvant anthracyclines (maximum cumulative dose, 360 mg/m^2 doxorubicin or 750 mg/m^2 epirubicin)
- At least 4 weeks since prior surgery, radiotherapy, endocrine therapy, or experimental drug therapy with complete recovery from the effects of these interventions
- It is recommended that all baseline staging should be completed within 35 days prior to study entry. All subjects will have the following workup as applicable; CT scan of brain, CT scan or MRI of chest and abdomen, and bone scan or PET scan. In cases of positive bone or PET scans, bone X-ray evaluation and/or MRI is required to confirm or exclude metastatic bone disease. Subjects with metastatic disease limited to bone are ineligible unless at least one lytic lesion is measurable and can be followed by RECIST criteria. Other tests may be performed as clinically indicated
- Normal cardiac function must be confirmed by left ventricular ejection fraction (LVEF) of >/= 50% or shortening fraction (multiple-gated acquisition [MUGA] scan or echocardiography respectively). The result must be greater than the lower limit of normal (LLN) for the institution.
- Subjects receiving bisphosphonate therapy; however, if bisphosphonates were started within /= 2
- Presence of any non-healing wound, fracture, or ulcer, or the presence of clinically significant (>/= Grade 2) peripheral vascular disease
- History of any other malignancy within the past 5 years, with the exception of non-melanoma skin cancer or carcinoma in-situ of the cervix
- Clinically significant cardiovascular disease
- Active peptic ulcer disease, inflammatory bowel disease, or other gastrointestinal condition increasing the risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to beginning therapy
- History of bleeding diathesis or coagulopathy
