E.3 | Principal inclusion criteria |
1. Signed informed consent prior to initiation of any study-specific procedures or treatment, as confirmation of the patient’s awareness and willingness to comply with the study requirements 2. Female patients ≥18 years of age 3. Histologically confirmed HER2-negative adenocarcinoma of the breast with documented progression of disease per investigator assessment following or during first-line treatment with bevacizumab in combination with chemotherapy for LR or mBC; patients can have measurable or non-measurable disease. 4. A minimum of 4 cycles of bevacizumab 15 mg/kg or 6 cycles 10 mg/kg received in the first-line setting. Note: patients who have received bevacizumab treatment as part of (neo-) adjuvant therapy are eligible but these bevacizumab cycles do not count towards the minimum required number of cycles. 5.

E.4 | Principal exclusion criteria |
Disease-specific exclusions 1. Patients who have received anti-angiogenic therapy or anti-vascular endothelial growth factors other than bevacizumab for the first-line treatment of LR/mBC 2. Patients who have exclusively received endocrine treatment in combination with bevacizumab until the first progression 3. Positive or unknown HER2/neu status or for whom determination of HER2 status is not possible. In general, HER2-positive status will be identified by a FISH assay as evaluated at the institution, or, if FISH is unavailable, a 2+ or 3+ immunohistochemistry result. 4. Current, recent or planned participation in an experimental drug study - other than a bevacizumab breast cancer study. 5.

Serum chemistry: Total bilirubin >1.5 times ULN AST or ALT >2 times ULN ALP >2 times ULN 7. Inadequate renal function, defined as: Creatinine clearance <50 mL/min Urine dipstick for proteinuria ≥2+ unless a 24-hour protein ≤1 g is demonstrated 8. Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would prevent the patient from meeting the study requirements 9. Serious active infection requiring i.v. antibiotics and/or hospitalization at study entry 10. Patients who are treated with any medicinal product that contraindicates the use of any of the study drugs, may interfere with the planned treatment, affects patient compliance or puts the patient at high risk for treatment-related complications Bevacizumab-specific exclusions 11. Inadequately controlled hypertension while receiving anti-hypertensive medication 12. Prior history of hypertensive crisis or hypertensive encephalopathy 13. Prior history of nephrotic syndrome 14. New York Heart Association (NYHA) Class II or greater congestive heart failure (CHF). Note: For those patients where it is indicated an ECHO/MUGA must be performed. The LVEF must be above the institutional lower limit of normal in order for the patient to be eligible. 15. History of myocardial infarction or unstable angina within 6 months prior to day 1 16. History of stroke or transient ischemic attack (TIA) within 6 months prior to day 1 17. Known CNS disease, except for treated brain metastases. Treated brain metastases are defined as: having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging during the screening period. Anticonvulsants are allowed. Treatment for brain metastases may include whole brain radiotherapy, radiosurgery or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to day 1 are excluded. A brain or MRI scan is required within 28 days prior to day 1 if the presence of untreated brain metastases is suspected. 18. Significant vascular disease within 6 months prior to day 1 19. Any previous venous thromboembolism > NCI-CTCAE Grade 3 20. History of hemoptysis within 1 month prior to day 1 21. Evidence of bleeding diathesis or significant coagulopathy. 22. Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to day 1, or anticipation of need for major surgical procedure during the course of the study 23. Core biopsy or other minor surgical procedure, excluding placement of a vascular access device, within 7 days prior to day 1 24. History of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess or active gastrointestinal bleeding within 6 months prior to day 1 25. Serious, non-healing wound, active ulcer, or untreated bone fracture 26. Known hypersensitivity to any component of bevacizumab or any of the study drugs 27. Pregnant or lactating females. 28. Chronic, daily treatment with high-dose aspirin or clopidogrel 29. Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of bevacizumab or any of the study drugs that may affect the interpretation of the results or render the patient at high risk for treatment complications.
