Therapy With Bevacizumab (BEV), Doxorubicin, and Cyclophosphamide Followed by BEV, Docetaxel, and Capecitabine Before Surgery Followed by BEV Alone After Surgery for Women With Locally Advanced Breast Cancer

Study Overview
=================
Brief Summary
-----------------
Bevacizumab is an angiogenesis inhibitor which means it works to stop blood vessel formation in tumors. Without new blood vessels, the growth of a tumor is slowed. Chemotherapy drugs kill cancer cells more directly. This study will evaluate: How bevacizumab, given with chemotherapy before surgery, and then bevacizumab given alone after surgery, will affect locally advanced breast tumors Side effects from adding bevacizumab to chemotherapy Whether adding bevacizumab to chemotherapy for breast cancer will affect the heart If receiving bevacizumab will have any effect on how patients recover from surgery Side effects of the combinations of drugs used in this study

Detailed Description
-----------------
Initial trials of neoadjuvant chemotherapy administered for locally advanced tumors, including those in breast cancer, demonstrated therapy could induce sufficient tumor regression to allow for the resection of otherwise unresectable tumors. Subsequent demonstration of the equivalence of lumpectomy to mastectomy in patients with operable breast cancer, stimulated interest in the concept of using preoperative chemotherapy to reduce large, but operable, primary tumors to allow for lumpectomy in women who would otherwise require a mastectomy. Given the data from previous studies, it is appropriate to continue development of sequential doxorubicin/cyclophosphamide/docetaxel regimens to improve on clinical and pathologic response rates. FB-4 is a Phase II, single arm study for women with locally advanced human epidermal growth factor receptor 2 (HER2)-negative breast cancer diagnosed by core needle biopsy. The primary aim of the study is to determine the pathologic complete response rate in the breast following neoadjuvant chemotherapy combined with bevacizumab.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patients must be female. The patient must be greater than/equal to 18 years old The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy or limited incisional biopsy. Patients must have clinical Stage IIIA, IIIB, or IIIC disease (American Joint Committee on Cancer [AJCC] staging criteria) with a primary breast tumor that is greater than/equal to 2.0 cm measured by clinical exam, unless the patient has inflammatory breast carcinoma, in which case measurable disease is not required. Patients must have the ability to swallow oral medication. The patient's Eastern Cooperative Oncology Group (ECOG) performance status must be 0 or 1. At the time of study entry, blood counts must meet the following criteria: Absolute neutrophil count (ANC) must be greater than/equal to 1200/mm3. Platelet count must be greater than/equal to 100,000/mm^3. Hemoglobin must be greater than/equal to 10 g/dL. The following criteria for evidence of adequate hepatic function must be met: total bilirubin must be less than/equal to upper limit of normal (ULN) for the lab unless the patient has a grade 1 bilirubin elevation (greater than ULN to 1.5 x ULN) due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and alkaline phosphatase must be less than 2.5 x ULN for the lab; and aspartate aminotransferase (AST) must be less than/equal to 1.5 x ULN for the lab. Alkaline phosphatase and AST may not both be greater than the ULN. For example, if the alkaline phosphatase is greater than the ULN but less than/equal to 2.5 x ULN, then the AST must be less than/equal to the ULN. If the AST is greater than the ULN but less than/equal to 1.5 x ULN, then the alkaline phosphatase must be less than/equal to ULN. Patients with either skeletal pain or alkaline phosphatase that is greater than ULN but less than/equal to 2.5 x ULN are eligible for inclusion in the study if a bone scan or positron emission tomography (PET) scan does not demonstrate metastatic disease. Patients with suspicious findings on bone scan or PET scan are eligible if suspicious findings are confirmed as benign by x-ray, magnetic resonance imaging (MRI), or biopsy. Patients with AST or alkaline phosphatase greater than ULN are eligible for inclusion in the study if liver imaging (computed tomography [CT], MRI, or PET scan) does not demonstrate metastatic disease and adequate hepatic function. The following criteria for evidence of adequate renal function must be met: Serum creatinine less than/equal to ULN for the lab. Calculated creatinine clearance must be greater than 50 mL/min. Urine protein/creatinine (UPC) ratio must be less than 1.0. Patients must have their left ventricular ejection fraction (LVEF) assessed by multigated acquisition (MUGA) scan or echocardiogram within 3 months prior to study entry. The LVEF must be greater than/equal to the lower limit of normal (LLN) for the cardiac imaging facility performing the MUGA scan or echocardiogram. Note: If the cardiac imaging facility cannot provide a LLN, use 50% as the LLN value. Note: Since the pre-entry LVEF serves as the baseline for comparing subsequent LVEF assessments to determine if bevacizumab therapy can be continued following doxorubicin and cyclophosphamide (AC) and postoperatively, it is critical that this baseline study be an accurate assessment of the patient's LVEF. If the baseline LVEF is greater than 65%, the MUGA scan or echocardiogram must be repeated prior to study entry. The lower of the two LVEF values should be used as the baseline LVEF. Patients must have an electrocardiogram (EKG) within 3 months prior to study entry. Exclusion Criteria: Tumor determined to be strongly HER2-positive by immunohistochemistry (3+) or by fluorescent in situ hybridization (positive for gene amplification). Excisional biopsy for this primary tumor. Synchronous bilateral invasive breast cancer. Surgical axillary staging procedure prior to study entry (Exceptions: 1) fine needle aspiration (FNA) of an axillary node is permitted for any patient, and 2) although not recommended, a sentinel lymph node biopsy for patients with clinically negative axillary nodes is permitted.) History of any of the following cancers: Ipsilateral breast cancer: invasive, ductal carcinoma in situ (DCIS) treated with any therapy other than excision Contralateral breast cancer: invasive within the past 5 years (Patients with history of DCIS or synchronous DCIS are eligible) History of non-breast malignancies within the 5 years prior to study entry.

Prior therapy with anthracyclines, taxanes, capecitabine, or bevacizumab for any malignancy. Treatment including radiation therapy, chemotherapy, biotherapy, and/or hormonal therapy administered for the currently diagnosed breast cancer prior to study entry. The only exception is hormonal therapy, which may have been given for up to a total of 28 days anytime after diagnosis and before study entry. In such a case, hormonal therapy must stop at or before study entry and be re-started, if indicated, following chemotherapy. Any of the following cardiac conditions: angina pectoris that requires the use of anti-anginal medication; history of documented congestive heart failure; serious cardiac arrhythmia requiring medication; severe conduction abnormality; valvular disease with documented cardiac function compromise; or uncontrolled hypertension defined as blood pressure greater than 150/90 on antihypertensive therapy.

Patients are eligible only if these medications are discontinued prior to study entry. Any sex hormonal therapy, e.g., birth control pills, ovarian hormonal replacement therapy, etc. These patients are eligible if this therapy is discontinued prior to study entry. (Women of reproductive potential must agree to use an effective non-hormonal method of contraception during study therapy and for at least 3 months after completion of bevacizumab.) Pregnancy or lactation at the time of study entry. Use of any investigational agent within 4 weeks prior to enrollment in the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pathologic Complete Response (pCR) in the Breast | Measured by no histologic evidence of invasive tumor cells in the surgical breast specimen | Approximately 7 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pCR in the Breast and Nodes | Measured by no histologic evidence of invasive tumor cells in the surgical breast specimen, axillary nodes, or sentinel nodes | Approximately 7 months | 
| Clinical Response Rate (cRR) of the Sequential Regimen | Clinical tumor measurements were required before study entry & before cycle 5 of chemotherapy (between AC & TX). Final tumor measurements were obtained 4-5 weeks after the last dose of chemotherapy. Clinical tumor assessments by physical examination were recommended before each chemotherapy cycle. The criteria proposed by the Response Evaluation Criteria in Solid Tumors Committee(RECIST) were used to define clinical response status. CR was defined as the disappearance of all lesions with no evidence of PD. PR was defined as at least 30% decrease in the sum of the longest diameter of target lesions, using as reference the baseline sum longest diameter and/or the persistence of greater than or equal to 1 nontarget lesion without worsening of any other clinical manifestations of disease. PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, the appearance of new lesions, or unequivocal progression of existing lesions. | Approximately 6 months | 
| Reported Adverse Events | Number of Adverse Events | Approximately 14 months | 
| Cardiac Events | Events: Congestive Heart Failure; Cardiac Death | Assessments throughout; up to 18 months following study entry | 
| Progression-free Survival | Percentage of patients free from disease progression. Progression is determined using international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee. At least a 20% increase in the sum of the longest diameter of the target lesions. Other manifestations of progressive disease would also be classified as disease progression, eg., appearance of one or more new lesions in the breast, regional lymph nodes or distant sites, unequivocal progression of existing non-target lesions, and appearance of inflammatory carcinoma on clinical exam. | 2 years | 
| Overall Survival | Percentage of patients alive. | 2 years | 
| Number of Patients With at Least One Surgical Complications (Wound Dehiscence, Infection, Seroma, or Hematoma). | Number of patients with at least one surgical complications (wound dehiscence, infection, seroma, or hematoma) | Two (2) years |
