Celecoxib in Preventing Polyps in Patients Who Have Undergone Surgery for Stage I Colon Cancer

• Status: Terminated
• Trial end date: 2006-04-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. It is not yet known whether celecoxib is effective in preventing polyps in patients with colon cancer.

PURPOSE: Randomized phase III trial to study the effectiveness of celecoxib in preventing the development of polyps in patients who have undergone surgery for stage I colon cancer.

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

Details

• Lead Sponsor: NSABP Foundation Inc
• Collaborator: National Cancer Institute (NCI)
• Treatments: Celecoxib

Criteria
