Trastuzumab and Exemestane in Treating Postmenopausal Women With Metastatic or Locally Advanced Breast Cancer
RATIONALE: The monoclonal antibody trastuzumab can locate breast cancer cells that have HER2 on their surface and either kill them or deliver tumor-killing substances to them without harming normal cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using exemestane may fight breast cancer by reducing the production of estrogen. Combining trastuzumab with exemestane may be an effective treatment for breast cancer with high amounts of HER2.
PURPOSE: Phase II trial to study the effectiveness of combining trastuzumab with exemestane in treating postmenopausal women who have metastatic or locally advanced HER2-positive breast cancer.
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase II Study Of Herceptin And Exemestane For Treatment Of Postmenopausal Women With Metastatic Hormone-Responsive, HER2/NEU Positive Breast Cancer|
|Study Start Date:||July 2002|
|Estimated Study Completion Date:||August 2004|
|Estimated Primary Completion Date:||August 2004 (Final data collection date for primary outcome measure)|
- Determine the efficacy of exemestane and trastuzumab (Herceptin), in terms of response rate and time to progression, in postmenopausal women with metastatic or locally advanced hormone-responsive, HER2/neu positive breast cancer.
- Determine the toxicity of this regimen in these patients.
OUTLINE: This is a multicenter study.
Patients receive trastuzumab (Herceptin) IV over 30-90 minutes on day 1 and oral exemestane once daily. Treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months.
PROJECTED ACCRUAL: A total of 18-60 patients will be accrued for this study.
