Pioglitazone Hydrochloride in Preventing Head and Neck Cancer in Patients With Oral Leukoplakia

• Status: Completed
• Trial end date: 2010-01-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well pioglitazone hydrochloride works in preventing head and neck cancer in patients who have oral leukoplakia. Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of pioglitazone hydrochloride may be effective in preventing head and neck cancer.

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

Details

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