• Status: Withdrawn
• Trial end date: 2005-12-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of celecoxib may be an effective way to prevent actinic keratoses.

PURPOSE: Randomized phase II/III trial to determine the effectiveness of celecoxib in preventing skin cancer in patients who have actinic keratoses.

• Phase: Phase 2/Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Alabama at Birmingham
• Collaborator: National Cancer Institute (NCI)
• Treatments: Celecoxib
