Celecoxib in Preventing Basal Cell Carcinoma in Patients With Basal Cell Nevus Syndrome

• Status: Completed
• Trial end date: 2007-07-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. The use of celecoxib may be an effective way to prevent the development of basal cell carcinoma.

PURPOSE: Randomized phase II trial to determine the effectiveness of celecoxib in preventing basal cell carcinoma in patients who have basal cell nevus syndrome.

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

Details

• Lead Sponsor: University of California, San Francisco
• Collaborator: National Cancer Institute (NCI)
• Treatments: Celecoxib
