Docetaxel, Epirubicin, and Cyclophosphamide With or Without Trastuzumab in Treating Women With Locally Advanced Breast Cancer That Can Be Removed By Surgery

Breast Cancer Clinical Trial

Official title: Evaluation of Response Rate to Pre-Operative Docetaxel + Herceptin Study Part A and Docetaxel Study Part B in Locally Advanced Breast Cancer Patients, Stratified by HER2-Status Trial - PHASE II [(Herceptin Docetaxel Neoadjuvant) HEDON]

Status Active, not recruiting

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as docetaxel, epirubicin, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, 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. Giving chemotherapy with or without monoclonal antibody therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying how well giving docetaxel, epirubicin, and cyclophosphamide with or without trastuzumab works in treating women with locally advanced breast cancer that can be removed by surgery.

Clinical Trial Description

OBJECTIVES:

• Determine the efficacy of neoadjuvant therapy comprising docetaxel and trastuzumab (Herceptin®) and adjuvant therapy comprising epirubicin hydrochloride, cyclophosphamide, and trastuzumab (Herceptin®) followed by radiotherapy in women with locally advanced, HER2-positive, operable breast cancer.

• Determine the efficacy of neoadjuvant therapy with docetaxel and adjuvant therapy comprising epirubicin hydrochloride and cyclophosphamide followed by radiotherapy in women with locally advanced, HER2-negative, operable breast cancer.

OUTLINE: This is an open-label, prospective, multicenter study. Patients are stratified according to HER2 status (positive vs negative).

• Neoadjuvant therapy:

• Stratum 1 (HER2-positive disease): Patients receive trastuzumab IV over 30-90 minutes on days 1, 8, and 15 and docetaxel IV over 60 minutes on day 1. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity

• Stratum 2 (HER2-negative disease): Patients receive docetaxel IV alone as in stratum 1.

• Surgery: All patients undergo surgery in week 19.

• Adjuvant therapy: Beginning within 2 weeks after surgery, patients receive adjuvant therapy.

• Stratum 1 (HER2-positive disease): Patients receive trastuzumab IV over 30-90 minutes on days 1, 8, and 15, epirubicin hydrochloride IV over 30 minutes on day 2, and cyclophosphamide IV over 30 minutes on day 2. Treatment repeats every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients then receive trastuzumab IV alone every 3 weeks until week 52.

• Stratum 2 (HER2-negative disease): Patients receive epirubicin hydrochloride and cyclophosphamide as in stratum 1.

• Radiotherapy: Patients who undergo breast conserving surgery or patients who undergo mastectomy with ypN positive lymph nodes (i.e., > 4 positive lymph nodes) or ypT3 tumor (i.e., tumor size > 4 cm) undergo radiotherapy, beginning in approximately week 31 and continuing until up to week 38.

• Adjuvant endocrine therapy: Patients with estrogen receptor- or progesterone receptor-positive disease receive adjuvant endocrine therapy beginning in approximately week 31. Premenopausal patients ≤ 40 years of age receive goserelin for 2-3 years and tamoxifen citrate for 5 years.Premenopausal patients > 40 years of age receive tamoxifen citrate for 5 years. Postmenopausal patients receive anastrozole for 5 years years.

After completion of study treatment, patients are followed periodically for up to 5 years.

PROJECTED ACCRUAL: A total of 94 patients will be accrued for this study. ;
