Ixabepilone and Hydroxychloroquine in Treating Patients With Metastatic Breast Cancer

• Status: Terminated
• Trial end date: 2011-12-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as ixabepilone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Hydroxychloroquine may help ixabepilone work better by making tumor cells more sensitive to the drug.

PURPOSE: This phase I/II trial is studying the side effects and best dose of ixabepilone given together with hydroxychloroquine and to see how well they work in treating patients with metastatic breast cancer.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Medicine and Dentistry of New Jersey
• Collaborator: National Cancer Institute (NCI)
• Treatments: Epothilones; Hydroxychloroquine
