Why is this study being done?

PRIMARY OBJECTIVES:

I. Compare the disease-free survival (DFS) of patients with lymph node-positive or high-risk, lymph node-negative breast cancer treated with adjuvant therapy comprising doxorubicin hydrochloride, cyclophosphamide, and paclitaxel with vs. without bevacizumab.

SECONDARY OBJECTIVES:

I. Compare the overall survival of patients treated with these regimens. II. Determine the toxicity of these regimens. III. Compare the efficacy of short-term (20-24 weeks) vs long-term (50-54 weeks) bevacizumab, in terms of DFS, in these patients.

IV. Evaluate the association between outcomes (disease-free survival, overall survival and toxicities) and genotype (derived from candidate single nucleotide polymorphisms and genome wide evaluations).

V. Compare quality of life patients treated with these regimens, in terms of physical symptoms, physical functioning, psychological state and social functioning over an 18 month period. (QOL closed as of 05/28/10) VI. Determine the impact of theoretical biomarker information on patients' willingness to accept the toxicities of bevacizumab for the estimated potential benefit.

VII. Create a biospecimen repository including plasma, serum and CellSearch cassettes containing circulating tumor cells (CTC) for evaluating determinants of late relapse, including candidate biomarkers reflecting occult tumor burden (e.g., CTCs and plasma tumor DNA) and host factors (e.g., estrogen, insulin-IGF axis, inflammation, etc).

VIII. Create a biorepository of metastatic tumor samples in patients who have had a late relapse.

XV. Determine body mass index (BMI) and comorbidity burden in patients with operable breast cancer five or more years after diagnosis.

X. Determine whether there is a relationship between late relapse and BMI at diagnosis and at 5 years after diagnosis, and whether BMI-associated inflammatory and/or metabolic biomarkers are associated with early and late recurrence.

OUTLINE: This is a randomized, partially double-blind, placebo-controlled, partially open-label, multicenter study. Patients are stratified according to planned dose schedule of doxorubicin hydrochloride and cyclophosphamide (every 3 weeks vs every 2 weeks). Patients are further stratified according to estrogen receptor status (positive vs negative), lymph node involvement (node-negative vs 1-3 positive node[s] vs ≥ 4 positive nodes), and received/planned treatment (lumpectomy and whole breast radiation therapy vs lumpectomy and accelerated partial-breast radiation therapy [before or after chemotherapy] vs mastectomy without radiation therapy vs mastectomy [with local or regional]). Patients are randomized to 1 of 3 treatment arms (20% of patients are randomized to Arm I, 40% to Arm II, and 40% to Arm III).

ARM I: Patients receive doxorubicin hydrochloride IV, cyclophosphamide IV over 20-30 minutes, and placebo IV over 30-90 minutes on day 1. Treatment repeats every 2 or 3 weeks for 4 courses. Beginning 3 weeks later, patients then receive paclitaxel IV over 1 hour on days 1, 8, and 15 and placebo IV over 30-90 minutes on day 1. Treatment with paclitaxel and placebo repeats every 3 weeks for 4 courses.

ARM II: Patients receive doxorubicin hydrochloride and cyclophosphamide as in arm I and bevacizumab IV over 30-90 minutes on day 1. Treatment repeats every 2 or 3 weeks for 4 courses. Beginning 3 weeks later, patients then receive paclitaxel as in arm I and bevacizumab IV over 30-90 minutes on day 1. Treatment with paclitaxel and bevacizumab repeats every 3 weeks for 4 courses.

ARM III: Patients receive doxorubicin hydrochloride and cyclophosphamide as in arm I and bevacizumab as in arm II. Treatment repeats every 2 or 3 weeks for 4 courses. Beginning 3 weeks later, patients then receive paclitaxel as in arm I and bevacizumab as in arm II. Treatment with paclitaxel and bevacizumab repeats every 3 weeks for 4 courses. Beginning 2 months later, patients then receive open-label bevacizumab IV over 30-90 minutes on day 1. Treatment with bevacizumab alone repeats every 3 weeks for 10 courses.

In all arms, treatment continues in the absence of disease progression or unacceptable toxicity. Patients complete quality of life (QOL) questionnaires followed by telephone QOL interviews at baseline and periodically. (QOL closed as of 05/28/10)

After completion of study treatment, patients are followed periodically for up to 15 years.
