Clinical Trial Title

Cyclophosphamide And Doxorubicin (CA) (4 VS 6 Cycles) Versus Paclitaxel (4 VS 6 Cycles) As Adjuvant Therapy For Breast Cancer in Women With 0-3 Positive Axillary Lymph Nodes:A 2X2 Factorial Phase III Randomized Study

Trial Summary and Conditions

This randomized phase III trial studies cyclophosphamide and doxorubicin hydrochloride compared with paclitaxel as adjuvant therapy in treating breast cancer in women with 0-3 positive axillary lymph nodes. Giving additional cancer treatment after surgery may help to lower the risk that the cancer will come back (adjuvant therapy). Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether the standard adjuvant therapy of cyclophosphamide and doxorubicin hydrochloride is more effective than paclitaxel in treating women with breast cancer

Data Summary

Control and experimental arm data files include data on safety, efficacy, demographics, etc. See the data dictionary provided for more details.

Study Objectives

To determine the equivalence of paclitaxel given every two weeks with cyclophosphamide and doxorubicin hydrochloride (CA) given every two weeks as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for disease-free survival. To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for disease-free survival for women with primary breast cancer with 0-3 positive axillary lymph nodes. To determine the equivalence of paclitaxel given every two weeks with CA given every two weeks, and the potential superiority of longer vs. shorter therapy, in relation to overall survival, local control (regardless of metastatic status) and time to distant metastases (regardless of local recurrence status). To compare toxicities of short and long course CA and paclitaxel as adjuvant therapy for women with 0-3 positive axillary lymph node breast cancer. To determine the effect of long and short course CA and paclitaxel on the induction of menopause for pre-menopausal patients.

Outcome Measures

Primary Outcome Measures: Relapse Free Survival (RFS) 4 vs. 6 Cycles. To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for relapse-free survival for women with primary breast cancer with 0-3 positive axillary lymph nodes. An assessment of the superiority of 6 cycles over 4 cycles will be conducted. This analysis combines Arm I and Arm III together, and Arm II and Arm IV together. Duration of Disease Free Survival (RFS). To determine the equivalence of paclitaxel to CA as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for disease-free survival. Objective progression is defined as the appearance of local (chest wall, axillary, supraclavicular nodes) or distant metastases.
