Summary

The main purpose of this study is to learn if adding bevacizumab to standard treatment with chemotherapy (docetaxel, doxorubicin, and cyclophosphamide) for early stage HER2-negative breast cancer will prevent breast cancer from returning. A second purpose of this study is to learn if adding bevacizumab to treatment with chemotherapy will help women with HER2-negative breast cancer live longer. The researchers also want to learn about the side effects of the combination of drugs used in this study.

Detailed description

The B-46-I/07132 study, a multicenter, open-label, randomized Phase III, adjuvant therapy trial, will compare the value of adding bevacizumab to a non-anthracycline-based chemotherapy regimen relative to the same chemotherapy without bevacizumab and relative to an anthracycline-based chemotherapy regimen in women with resected node-positive or high-risk node-negative, HER2-negative breast cancer. This trial will determine whether the addition of bevacizumab to a regimen of docetaxel and cyclophosphamide (TCB) improves invasive disease-free survival relative to docetaxel and cyclophosphamide alone (TC). A secondary aim will be to determine whether the addition of bevacizumab to TC improves invasive disease-free survival compared to a regimen of docetaxel, doxorubicin, and cyclophosphamide (TAC). Other secondary aims include whether TCB improves disease-free survival, overall survival, and recurrence-free interval relative to TC alone and to TAC. The toxicities of the three regimens will also be compared. Patients in the B-46-I/07132 study will be randomized to one of three treatment regimens: Group 1 patients will receive 6 cycles of TAC administered every 21 days (docetaxel 75 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2); Group 2 patients will receive 6 cycles of TC administered every 21 days (docetaxel 75 mg/m2, cyclophosphamide 600 mg/m2); and Group 3 patients will receive 6 cycles of TCB every 21 days with bevacizumab therapy continuing every 21 days after completion of chemotherapy until 1 year following the first dose (docetaxel 75 mg/m2, cyclophosphamide 600 mg/m2, and bevacizumab 15 mg/kg). Primary prophylaxis with pegfilgrastim or filgrastim is required for Group 1 patients (optional for patients in Groups 2 and 3). Patients will also receive adjuvant radiation therapy as clinically indicated and endocrine therapy for hormone receptor-positive tumors. Tumor samples will be submitted for correlative science studies to evaluate predictors of study therapy benefit. Submission of a tumor sample is a study requirement for all patients.
