• Sex: Female
• Target Recruitment: Not specified

Inclusion Criteria

-Patients with histologically or cytologically confirmed, HER2/neu-negative, pre- or postmenopausal adenocarcinoma of the breast with measurable or non-measurable locally recurrent or metastatic disease, who are candidates for chemotherapy. Locally recurrent disease must not be amenable to resection and/or radiotherapy with curative intent.
-Documented ER/PR status
-HER2/neu-negative disease as determined by immunohistochemistry or FISH/CISH
-Prior adjuvant chemotherapy is allowed provided that the last dose of chemotherapy was not within 6 months (not within 12 months if taxane-based) prior to randomization.
-Prior maximum cumulative dose must not exceed 360 mg/m2 for doxorubicin and 720 mg/m2 for epirubicin
-Female only
-Age ? 18 years and = 75 years
-ECOG PS of 0 or 1
-Life expectancy of ? 12 weeks
-Able to comply with the protocol
-Written informed consent (Informed Consent document to be approved by the institution’s Independent Ethics Committee [IEC]) obtained prior to any study specific screening

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

-Previous chemotherapy for locally recurrent or metastatic breast cancer
•Prior hormonal therapy for locally recurrent or metastatic disease should have been discontinued at least 2 weeks before randomization.
•Patients with bone metastases only are allowed provided that they are on bisphosphonate treatment > 3 months.
-Patients who have received adjuvant radiotherapy as part of the treatment of early breast cancer are eligible if the last fraction of radiotherapy was administered at least 6 months prior to randomization. Radiotherapy administered for the relief of metastatic bone pain is allowed prior to study entry, but
•no more than 30% of marrow-bearing bone should have been irradiated
•the last fraction of radiotherapy should not have been administered within 3 weeks prior to randomization.
-Other primary tumors within the last 5 years before inclusion, except for adequately controlled basal cell carcinoma of the skin, or carcinoma in situ of the cervix
-Previous or current CNS metastases. A CT or MRI of the brain must be performed within 4 weeks prior to randomization if the presence of metastases at this site is suspected.
-Inadequate bone marrow function: ANC: < 1.5 x 109/L, platelet count < 100 x 109/L and hemoglobin < 6 mmol/L.
-Inadequate liver function.
-History or evidence or inherited bleeding diathesis or coagulopathy with the risk of bleeding
-History of cerebrovascular accident
-Arterial or venous thrombosis = 12 months prior to registration
-Uncontrolled hypertension or clinically significant cardiovascular disease.
-Inadequate left ventricular ejection fraction at baseline.
-Major surgical procedure, open biopsy or significant traumatic injury within 28 days prior to randomization, or anticipation of the need for major surgery during the course of the study treatment
