Trastuzumab and Erlotinib as First-Line Therapy in Treating Women With Metastatic Breast Cancer Associated With HER2/Neu Overexpression
Phase I/II Study Of Herceptin Combined With OSI-774 In The First-Line Treatment Of Metastatic Breast Cancer Associated With HER2/Neu Overexpression
RATIONALE: Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Biological therapies such as erlotinib may interfere with the growth of tumor cells and slow the growth of the tumor. Combining trastuzumab with erlotinib may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combining trastuzumab with erlotinib as first-line therapy in treating women who have metastatic breast cancer associated with HER2/neu overexpression.

Detaljert beskrivelse
OBJECTIVES:
- Determine the maximum tolerated dose and recommended phase II dose of erlotinib when combined with trastuzumab (Herceptin) as first-line therapy in women with metastatic breast cancer associated with HER2/neu overexpression. (Phase I closed to accrual as of 01/2004)
- Determine the safety profile of this regimen in these patients.
- Determine the rate and duration of objective response in patients treated with this regimen.
- Determine the pharmacologic behavior of this regimen in these patients.
- Determine time to disease progression and duration of survival in patients treated with this regimen.
- Correlate the antitumor activity of this regimen with epidermal growth factor receptor expression in these patients.
OUTLINE: This is a dose-escalation study of erlotinib. (Phase I closed to accrual as of 01/2004).
Patients receive oral erlotinib once daily beginning on day 2 and trastuzumab (Herceptin) IV over 30-90 minutes (1-4 hours after erlotinib) once weekly beginning on day 1. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of erlotinib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are treated at the recommended phase II dose.
Patients are followed every 2 months.
PROJECTED ACCRUAL: A total of 3-18 patients will be accrued for the phase I portion (closed to accrual as of 01/2004) and 27-81 patients will be accrued for the phase II portion of this study.

Complete Response: The disappearance of all signs of cancer in response to treatment. This does not always mean the cancer has been cured. Also called complete remission. Partial Response: A decrease in the size of a tumor, or in the extent of cancer in the body, in response to treatment. Also called partial remission. |
