Exclusion criteria

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
