Chemotherapy With or Without Bevacizumab in Treating Women With Stage I, Stage II, or Stage IIIA Breast Cancer That Can Be Removed By Surgery
Basic Trial Information
|Phase III||Biomarker/Laboratory analysis, Treatment||Closed||18 and over||NCI, Other||NSABP B-40|
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of breast cancer by blocking blood flow to the tumor. Giving chemotherapy and bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known which chemotherapy regimen is more effective with or without bevacizumab in treating breast cancer.
PURPOSE: This randomized phase III trial is studying six different chemotherapy regimens to compare how well they work with or without bevacizumab in treating women with stage I, stage II, or stage IIIA breast cancer that can be removed by surgery.
Further Study Information
- Compare the efficacy of docetaxel followed by doxorubicin hydrocloride and cyclophosphamide (AC) vs docetaxel and capecitabine followed by AC vs docetaxel and gemcitabine hydrochloride followed by AC, with or without bevacizumab, in terms of an increase in the rate of pathologic complete response (pCR) in the breast, in women with palpable or operable breast cancer.
- Compare docetaxel/capecitabine with AC vs docetaxel/gemcitabine hydrochloride with AC vs docetaxel with AC, with or without bevacizumab, in terms of the rate of pCR in the breast and all post-therapy lymph nodes evaluated histologically (pCR breast and nodes).
- Determine whether the addition of bevacizumab to the docetaxel/anthracycline-based regimens (docetaxel with AC, docetaxel and capecitabine with AC, and docetaxel and gemcitabine hydrochloride with AC) will increase the rate of pCR of the breast and nodes compared to the same docetaxel/anthracycline-based regimens without bevacizumab in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to tumor size (2-4 cm vs > 4 cm), nodal status (negative vs positive), hormone receptor status (estrogen receptor [ER]-positive and/or progesterone-receptor [PgR]-positive vs ER- and PgR-negative), and age (< 50 years vs ≥ 50 years). Patients are randomized to 1 of 6 treatment arms.
Core needle biopsies are performed at baseline. Tumor tissue samples are also collected during definitive surgery. Samples are examined for gene expression and polymorphism by reverse transcriptase-polymerase chain reaction analysis and chemoresponse assay (ChemoFx®).
After completion of study therapy, patients are followed periodically for 10 years.
PROJECTED ACCRUAL: A total of 1,200 patients will be accrued for this study.
- The patient must have consented to participate and must have signed and dated an appropriate Institutional Review Board (IRB)-approved consent form that conforms to federal and institutional guidelines for the study treatment and submission of pre-entry core biopsy material for correlative studies.
- Patients must be female.
- Patients must be 18 years of age or older.
- Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy.
- The primary breast tumor must be palpable and measure greater than or equal to 2.0 cm on physical exam.
- All 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 or equal to the lower limit of normal (LLN) for the cardiac imaging facility performing the study. 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, it is critical that this baseline study be an accurate assessment of the patient's LVEF. If the baseline LVEF is greater than 75%, the investigator should have the study reviewed for accuracy prior to study entry. Following study entry, the LVEF determination may be reviewed up until the time of the post-chemotherapy (preoperative) evaluation. Please note that if a more accurate value is obtained from the review of the baseline MUGA or echocardiogram, the correct value must be submitted to the NSABP before the post-chemotherapy (preoperative) MUGA or echocardiogram is performed or it cannot be used for managing postoperative bevacizumab.
- All patients must have an EKG within 3 months prior to study entry.
- At the time of randomization:
- Absolute neutrophil count (ANC) must be greater than or equal to 1200/mm3.
- Platelet count must be greater than or equal to 100,000/mm3.
- Hemoglobin must be greater than or equal to 10 g/dL.
- There must be evidence of adequate hepatic function by these criteria:
- Total bilirubin must be less than or equal to the ULN for the lab unless the patient has a grade 1 bilirubin elevation (greater than ULN to 1.5 x ULN) resulting from Gilbert's disease or similar syndrome due to slow conjugation of bilirubin; and
- Alkaline phosphatase must be less than or equal 2.5 x ULN for the lab; and
- Aspartate Aminotransferase (AST) must be less than or 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 or equal 2.5 x ULN, then the AST must be less than or equal the ULN. If the AST is greater than the ULN but less than or equal 1.5 x ULN, then the alkaline phosphatase must be less than or equal ULN.
- Patients with either skeletal pain or alkaline phosphatase that is greater than ULN but less than or equal 2.5 x ULN are eligible for inclusion in the study if bone scans do not demonstrate metastatic disease. Suspicious findings on bone scan must be confirmed as benign by x-ray, MRI, or biopsy.
- Patients with AST or alkaline phosphatase greater than ULN are eligible for inclusion in the study if liver imaging does not demonstrate metastatic disease and adequate bone marrow and liver function results as described above are met.
- The following criteria for evidence of adequate renal function must be met:
- Serum creatinine less than or equal ULN for the lab.
- Calculated creatinine clearance must be greater than 50 mL/min.

- Therapy with any hormonal agent such as raloxifene, tamoxifen, or other selective estrogen receptor modulator (SERM), either for osteoporosis or breast cancer prevention. (Patients are eligible only if these medications are discontinued prior to randomization.)
- Prior history of breast cancer, including DCIS. (Patients with a history of lobular carcinoma in situ [LCIS] are eligible.)
- Prior therapy with anthracyclines, taxanes, capecitabine, 5-FU, gemcitabine, or bevacizumab for any malignancy.
