Erlotinib and Gemcitabine in Treating Patients With Metastatic Breast Cancer Previously Treated With An Anthracycline and/or a Taxane

• Status: Completed
• Trial end date: 2009-01-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy such as gemcitabine work in different ways to stop tumor cells from dividing so they stop growing or die. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Combining gemcitabine with erlotinib may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining gemcitabine with erlotinib in treating patients who have metastatic breast cancer that has been previously treated with an anthracycline and/or a taxane.

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