Combination Chemotherapy With or Without Darbepoetin Alfa in Treating Women With Stage III Breast Cancer

Breast Cancer Clinical Trial

Clinical Trial Summary

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. Colony-stimulating factors, such as darbepoetin alfa, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving combination chemotherapy together with darbepoetin alfa after surgery may kill any tumor cells that remain after surgery. It is not yet known whether combination chemotherapy and darbepoetin alfa are more effective than combination chemotherapy alone in treating stage III breast cancer.

PURPOSE: This randomized clinical trial is studying how well giving combination chemotherapy together with darbepoetin alfa works compared to combination chemotherapy alone in treating women with stage III breast cancer.

Clinical Trial Description

OBJECTIVES:

Primary

• Compare the disease-free survival rate in women with stage III breast cancer treated with adjuvant chemotherapy with vs without darbepoetin alfa.

Secondary

• Compare local recurrence and overall survival in patients receiving these regimens.

• Compare toxicity of these regimens in these patients.

• Compare quality of life and fatigue frequency in patients treated with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according the chemotherapy regimen (CEF vs TAC). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive 1 of the following regimens:

• Regimen CEF: Patients receive cyclophosphamide IV, epirubicin hydrochloride IV, and fluorouracil IV on day 1.

• Regimen TAC: Patients receive docetaxel IV, doxorubicin hydrochloride IV, and cyclophosphamide IV on day 1.

Treatment repeats every 3 weeks for 6 courses in the absence of disease progression and unacceptable toxicity.

• Arm II: Patients receive 1 of the following regimens:

• Regimen CEF: Patients receive regimen CEF as in arm I. Patients receive darbepoetin alfa if hemoglobin falls to ≤ 13.0 g/dL. Darbepoetin alfa is discontinued when hemoglobin rises to > 14.0 g/dL.

• Regimen TAC: Patients receive TAC as in arm I and darbepoetin alfa as in arm II, regimen CEF.

Quality of life is assessed at baseline, before each chemotherapy course, at the completion of study therapy, and at 6 and 12 months.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 1,234 patients will be accrued for this study. ;
