GW572016 and Trastuzumab in Treating Patients With Metastatic Breast Cancer That Overexpresses HER2/Neu

Summary

RATIONALE: GW572016 may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Monoclonal antibodies, such as trastuzumab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Giving GW572016 with trastuzumab may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of GW572016 when given together with trastuzumab in treating patients with metastatic breast cancer that overexpresses HER2/neu.
