Celecoxib and Trastuzumab in Treating Women With Metastatic Breast Cancer

• Status: Completed
• Trial end date: 2004-02-01
• Target enrollment: 0
• Participant gender: Female

Summary

RATIONALE: Celecoxib may be effective in preventing the further development of cancer. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining trastuzumab with celecoxib may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining celecoxib and trastuzumab in treating women who have metastatic breast cancer that has not responded to previous trastuzumab.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Memorial Sloan Kettering Cancer Center
