BCIRG 006 (GMA TAX302) 

Multicenter phase III randomized trial comparing doxorubicin and cyclophosphamide followed by docetaxel (ACT) with doxorubicin and cyclophosphamide followed by docetaxel and trastuzumab (ACTH) and with docetaxel, carboplatin and trastuzumab (TCH) in the adjuvant treatment of node positive and high risk node negative patients with operable breast cancer containing the HER2neu alteration

    Rationale This study is based on the hypothesis that the high level of increased survival seen in the metastatic setting with Herceptin combined with chemotherapy will translate into increased disease free and overall survival in the adjuvant treatment of patients with tumors overexpressing the HER2neu proto-oncogene. It explores, in the clinical setting, the use of the two chemotherapies (Taxotere and platinum salts) that have shown the greatest level of synergy with Herceptin when combined; based on the laboratory findings of Dennis Slamon at UCLA. In addition, the TCH arm has the advantage of not containing an anthracyline component as the combination of Herceptin and anthracyclines has been shown to increase the cardiac toxicity of both agents. Another important feature of this trial is the use of the FISH test to determine HER2neu status. The feasibility of the TCH arm has been confirmed in two phase II studies, BCIRG 101 and 102.

    Major eligibility criteria
    • Histologically proven breast cancer

    • Stage T 1-3, N0 or N1, M0
    • One, of at least 6 resected nodes, positive for tumor; or zero among a minimum of 6 resected lymph nodes or negative sentinel node biopsy AND at least one of the following risk factors: Tumor size > 2 cm, estrogen receptor and progesterone receptor status is negative, histologic and/or nuclear grade 2-3, or age < 35 years
    • Tumor must be POSITIVE for HER2neu overexpression by FISH
    • Age 18 - 70 years, KPS > 80%
    • Normal bone marrow, liver, renal and cardiac function
    • No prior systemic therapy or RT for breast cancer
    • Informed consent
    Endpoints Primary: Disease Free Survival
    Secondary: Overall Survival, toxicity and quality of life, cardiac toxicity, and to evaluate pathologic and molecular markers for predicting efficacy.
    Number of Patients

      A total of 3,200 patients
      The following assumptions are made:

    • the proportions of patients who have no axillary lymph nodes involved (N0), 1 to 3 axillary lymph nodes involved (N1-3) and 4 or more axillary lymph nodes involved trial (N4+) will be, respectively, 20%, 50% and 30%
    • the DFS at 5 years of patients receiving ACT in these strata are, respectively, equal to about 67%, 57% and 42%
    • the overall DFS of all patients receiving ACT will be equal to about 55% (20% x 67% + 50% x 57% + 30% x 42%)
    • it is of clinical interest to detect a 7% improvement in 5-year DFS (i.e. an increase from 55% to 62%)
    • the overall error rate for a false positive outcome (a) is set to 5%, using two-sided significance tests. Since the three pairwise treatment comparisons will be of interest in the final analysis, the error rate for each comparison is set at a conservative level of 0.017
    • the error rate for a false negative outcome (b) is set to 20% i.e the power of the trial is set to 80% for the difference of clinical interest
