This randomized, double blind, placebo controlled trial will evaluate the impact of adding everolimus to the combination of weekly paclitaxel plus bevacizumab in the first-line treatment of women with HER2-negative metastatic breast cancer. Patients will be randomized (1: 1) to receive either paclitaxel/bevacizumab/everolimus (Treatment Arm 1) or paclitaxel/ bevacizumab/placebo (Treatment Arm 2). Patients will be evaluated for response to treatment every 8 weeks; responding and/or stable patients will continue treatment, with re-evaluations every 8 weeks, until tumor progression or intolerable toxicity occurs. Outcomes will be assessed for each treatment arm separately. This trial is not intended to compare treatment arms primarily. Any such analyses are exploratory and will be conducted without adjustment for multiple hypothesis testing.

- IHC 2-3+ AND FISH-negative (FISH ratio <2. 2).

6. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1. 7. Adequate hematologic function, defined by: · Absolute neutrophil count (ANC) >1500/mm3

- Platelet count >=100,000/mm3

- Hemoglobin >9 g/dL

8. Adequate liver function, defined by: · AST and ALT <=2. 5 x the upper limit of normal (ULN) or <=5 x ULN in presence of liver metastases

- Total bilirubin <=1. 5 x ULN

9. Adequate renal function, defined by: · Serum creatinine <=1. 5 x ULN or calculated creatinine clearance of >=40 ml/min 10. International normalized ratio (INR) <=1. 5 or prothrombin time (PT)/partial thromboplastin time (PTT) within normal limits (WNL) of the institution (if patient is not on anti-coagulation therapy). Patients receiving anti-coagulation treatment with an agent such as warfarin or heparin are eligible if the INR is stable and within the therapeutic range prior to study treatment initiation. 11. Adequate lipid profile: total cholesterol <=300 mg/dL OR <=7. 75 mmol/L and fasting triglyceride 2. 5 x ULN. Note: In case one or both of these thresholds are exceeded,the patient can only be included after initiation of appropriate lipid lowering medication. 12. Patients with proteinuria at screening as demonstrated by either: · Urine protein creatinine (UPC) ration >1. 0 at screening or

- Urine dipstick for proteinuria >=2+ (patients discovered to have

>=2+ proteinuria on dipstick urinalysis at baseline should undergo a 24 hour urine collection and must demonstrate <1 g of protein in 24 hours to be eligible). 13. Measurable disease by RECIST criteria. 14. Life expectancy >=12 weeks. 15. Ability to swallow oral medications. 16. Adequate cardiac function, defined by baseline left ventricular ejection fraction (LVEF) value >= normal per institutional guidelines by MUGA scan or echocardiogram (ECHO). 17. Adequate recovery from recent surgery.

- Major surgical procedure >28 days from study entry

- Minor surgical procedure >7 days from study entry (Portacath placement

excepted - patients can start treatment <7 days after portacath placement.)

18. Patients with previous history of invasive cancers (including breast cancer) are eligible if definitive treatment was completed more than 5 years prior to initiating current study treatment, and there is no evidence of recurrent disease. 19. Patient must be accessible for treatment and follow-up. 20. All patients must be able to understand the investigational nature of the study and give written informed consent prior to study entry.


Exclusion Criteria: 1. Patients with active brain metastases or meningeal metastases. Patients who have had brain metastases resected, or have received brain radiation therapy >4 weeks prior to study entry are eligible, if they meet all of the following criteria: 1) residual symptoms < grade 2, 2) no dexamethasone requirement, and 3) follow-up MRI shows regression of lesions after treatment and no new lesions appearing. 2. Previous treatment with an m-TOR inhibitor (sirolimus, temsirolimus, everolimus) or anti-angiogenesis agent unless:

- in the adjuvant setting, and

- >=12 months prior to recurrence.

3. Previous radiotherapy for metastatic disease completed <2 weeks prior to study treatment initiation. 4. Patients who are current receiving systemic cancer therapy or have received previous systemic therapy within 4 weeks of the start of study drug (e. g. chemotherapy, antibody therapy, targeted agents). 5. Women who are pregnant or lactating. All patients with reproductive potential must agree to use effective contraception from time of study entry until at least 3 months after the last administration of study drug. 6. Uncontrolled hypertension defined as systolic blood pressure >150 mmHg or diastolic pressure >100 mmHg, despite optimal medical management. 7.

Patients who have any severe and/or uncontrolled medical conditions or other conditions that could affect their participation such as:

- severe impaired lung functions as defined as spirometry and DLCO that is 50% of

- uncontrolled diabetes as defined by fasting serum glucose >1. 5 x ULN.

17. History of any other disease, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug, or that might affect interpretation of the results of this study, or render the subject at high risk for treatment complications. 18.
