Inclusion criteria

Inclusion criteria: 1) Signed written informed consent 2) Men or women ages = 18 years 3) Histologic or cytologic confirmed diagnosis of invasive adenocarcinoma originating in the breast with evidence of locally recurrent or metastatic disease. 4) At least one target lesion per RECIST criteria (Section 3.3). Locally recurrent disease must not be amenable to resection with curative intent. Previously radiated area(s) must not be the only site of disease. 5) Subjects must not have received cytotoxic chemotherapy for locally recurrent/metastatic disease. (Subjects may have received adjuvant or neo adjuvant chemotherapy) 6) Subjects who received prior adjuvant or neoadjuvant taxane therapy must have relapsed = 12 months after completing therapy. 7) Subjects must not have breast cancer known to over express or amplify Her-2 (i.e., 3+ by immunohistochemistry and/or FISH positive). 8) Prior hormonal therapy in adjuvant, recurrent or metastatic setting is allowed, but this must have been discontinued at least 2 weeks prior to randomization. 9) Karnofsky performance status (PS) of 80-100 (or ECOG, PS of 0-1). 10) Estimated life expectancy of at least 12 weeks. 11) Recovery (except for alopecia) from recent therapy, including chemotherapy, immunotherapy, biological therapy or investigational product. Any such therapy must have been completed at least 3 weeks prior to randomization and at least 6 weeks from use of nitrosourea, or mitomycin. 12) Recovery from recent surgery and radiation therapy. At least one week must have elapsed from minor surgery (e.g. placement of venous access device or fine needle aspiration) and/or focal/palliative radiation therapy; at least 3 weeks from radiation and at least 4 weeks from major surgery. 13) Absolute neutrophil count (ANC) = 1500/mm3, 14) Hemoglobin = 9 g/dL, 15) Platelets = 100,000/mm3 16) Total bilirubin = 1.5 x times the upper limit of normal (ULN) 17) AST or ALT = 2.5 x ULN 18) Normal PTT and either INR or PT 60 mL/min (measured or calculated by Cockcroft-Gault method) 20) Negative or trace proteinuria on dipstick. (If proteinuria on dipstick is = 1+, a 24 hr urine collection is required to confirm =65 years) yes F.1.3.1 Number of subjects for this age range

Exclusion criteria

Exclusion criteria: 1) WOCBP unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and up to 8 weeks after treatment withdrawal. 2) Women who are pregnant or breastfeeding 3) Women with a positive pregnancy test on enrollment or prior to study drug administration. 4) Evidence of baseline sensory or motor neuropathy. 5) Serious intercurrent infections or non-malignant medical illnesses that are uncontrolled or the control of which may be jeopardized by this therapy. 6) History of abdominal fistula, GI perforation, intra-abdominal abscess, or serious gastric ulcer or bone fracture within 6 months prior to study entry. 7) Clinically significant cardiovascular disease (e.g. unstable angina, congestive heart failure, uncontrolled hypertension (>150/90), myocardial infarction or cerebral vascular accidents) within 6 months prior to study entry. 8) Prior history of high dose chemotherapy with bone marrow transplant or peripheral blood stem cell transplant within the previous 2 years. 9) Prior treatment with an epothilone (or epothilone analogue) or bevacizumab. 10) History of bleeding diathesis, pulmonary embolism, deep vein thrombosis or use of therapeutic anticoagulants as therapy. (Low dose anticoagulant therapy to maintain vascular access is allowed) 11) Concurrent non-healing wound or fracture. 12) Any current or previous history of brain and/or leptomeningeal metastases including evidence of cerebral edema by computerized tomography (CT) or magnetic resonance imaging (MRI). Head CT or MRI must be obtained within 4 weeks prior to randomization. 13) Psychiatric disorders or other conditions rendering the subject incapable of complying with the requirements of the protocol. 14) Any concurrent active malignancy other than non-melanoma skin cancer or carcinoma in situ of the cervix. (Subjects with a history of previous malignancies but without evidence of disease for 5 years will be allowed to enter the trial). 15) Known human immunodeficiency viral (HIV) infection. 16) Known allergy to any of the study drugs or their excipients such as, prior severe HSR to agents containing Cremophor®EL; or allergies to Chinese hamster ovary cell proteins or other recombinant humanized antibodies. 17) Subjects must not continue or institute treatment with the following strong inhibitors of CYP3A4 from 72 hours prior to the initiation of study therapy until end of treatment with ixabepilone or paclitaxel: amiodarone, clarithromycin, amprenavir, delavirdine, voriconazole erythromycin, fluconazole, itraconazole, ketoconazole, indinavir, nelfinavir, ritonavir, and saquinavir. 18) Other concurrent anti-tumor chemotherapy, hormonal therapy, immunotherapy regimens or radiation therapy, standard or investigational (see Section 6.4.2). 19) Aspirin (>325 mg/day), or non-steroidal anti inflammatory medications and other medications known to inhibit platelet function (e.g. dipyridamole, ticlopidine, clopidogrel or cilostazol) within 10 days of randomization. 20) Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness.

Primary

MeasureTime frame
Main Objective: To estimate the response rate of ixabepilone/bevacizumab combination in each of the following 2 schedules relative to the reference arm of paclitaxel plus bevacizumab: • Ixabepilone administered every week for 3 weeks followed by 1 week rest plus bevacizumab administered every 2 weeks (Arm A) and • Ixabepilone administered every 3 weeks plus bevacizumab administered every 3 weeks (Arm B).;Secondary Objective: • To determine the week 24 PFS rate • To estimate the progression free survival for the 3 treatment arms • To determine time to response for the 3 treatment arms • To determine the duration of response for the 3 treatment arms • To estimate overall survival for the 3 treatment arms • Determine the safety and tolerability of these schedules in this subject population for the 3 treatment arms;Primary end point(s): - The primary efficacy endpoint is the overall response rate (RR) defined for each arm as the number of subjects with best tumor response on-study of CR or PR divided by the number of randomized subjects in the arm. Secondary endpoints are 24 week PFS rate, time to response, duration of response and overall survival. - Exploratory analyses will assess the impact on QOL using the EORTC QLQ-C30© and the Herth Hope Index© for all randomized subjects, who meet the PRO evaluation criteria (see Protocol Section 3.3.11). - The safety profile of the three treatment arms will be assessed through summaries of adverse events, serious adverse events, deaths, adverse events leading to discontinuation and laboratory abnormalities in hematology, liver function and renal parameters for all treated subjects.
