Vorinostat in Treating Women Who Are Undergoing Surgery For Newly Diagnosed Stage I -III Breast Cancer

• Status: Completed
• Trial end date: 2013-05-01
• Target enrollment: 0
• Participant gender: Female

Summary

This phase II trial is studying how well vorinostat works in treating women who are undergoing surgery for newly diagnosed stage I, stage II, or stage III breast cancer. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vorinostat before surgery may shrink the tumor so that it can be removed.

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

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Vorinostat
