Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized, placebo-controlled Phase I/II multi-center trial, of the safety and efficacy of Celecoxib in a cohort of 81 HNPCC subjects and gene carriers. The three proposed intervention arms are: Celecoxib (to be provided by Searle) will be administered at 200mg p.o. BID x 12 months or 400mg p.o. BID x 12 months vs. Placebo p.o. BID x 12 months. Assessment of endoscopic and tissue-based biomarker endpoints will be conducted at baseline and 12 months on study drug or placebo. Patients that present with polyps at baseline will undergo a month 4 endoscopy. Plasma drug trough samples for pharmacokinetic analyses will be collected at baseline and month 12. NCI-Chemoprevention Branch will coordinate the efforts and activities of all sites.

Safety monitoring will occur via in-patient interviews with exams at month twelve; symptom questionnaires completed at baseline, months one, four, eight and twelve; blood and urinalysis at baseline and at months one, four, eight and twelve. A post-administration telephone call to evaluate side effect resolution will occur at months 13-14 for patients who have unresolved adverse events at the end of month 12.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Ability to participate in the scheduled follow-up tests.

No significant medical or psychiatric problems which would make the patient a poor protocol candidate, in the opinion of the principal investigator.

No "unacceptable clinical risk" to proceed (based upon the subclinical discoveries made via baseline colonoscopy and biopsies) including a previously-unknown bleeding diathesis, a new diagnosis of carcinoma, suspicion that the subject may require colectomy (complete or partial) within eighteen months of randomization.

Patient must not have undergone a colectomy within the past 6 months.

Patient must not have undergone chemotherapy within the past 6 months.

Patient must not have received pelvic radiation.
