Description
Inclusion Criteria:
- The subject has had a documented colonoscopy to the cecum, by a study physician, with adequate preparation resulting in diagnosis and clearance of an adenomatous polyp(s) within 24 weeks prior to study entry; the 24- week period begins from the time of colonoscopy, which had resulted in full visualization of colon/rectum or the time of removal of adenoma which ever had occurred first
At the baseline colonoscopy, the subject must have one of the following documented:
One adenomatous polyp > 6 mm;
- If the colonoscopy report says that a 6 mm polyp was removed, and the local pathology report confirms that this adenoma was AT LEAST 6mm in any dimension, the subject is eligible
- If the colonoscopy report says that the 6mm polyp was removed, and the local pathology report says that multiple fragments of adenoma were obtained, the subject is eligible
- If the colonoscopy report says that a 6mm polyp was removed, but the pathologist measured this as 5mm or less in greatest dimension, the subject is NOT eligible
- Two or more adenomatous polyps of any size documented by local pathology report plus colonoscopy report; or
- One adenomatous polyp of any size and a documented history of adenomatous polyp(s); if the colonoscopy report indicates that polyps of any size were left in the subject, the subject is NOT eligible; if the colonoscopy report says that all visible adenomas were removed, the subject is eligible.

- Willingness to continue with follow-up contacts every 6 months for collecting concomitant medications use data and end-of-study colonoscopy at Year 5
- The subject has signed and dated a separate informed consent document prior to performing any follow-up procedures; while delay in obtaining consent is not optimal, patients may be consented and entered into the post-treatment follow-up study at any time prior to their Year 5 colonoscopy but no later than 1Q2007
Exclusion Criteria:
- The subject has a history of Familial Adenomatous Polyposis or Hereditary Non-Polyposis Colorectal Cancer (as defined by the Amsterdam Criteria)

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of subjects with newly detected adenomas, and will be estimated using the life table method for each treatment group
Time Frame: Year 3 (cumulative for year one and year three)
|
Will be estimated using the life table method for each treatment group and compared using a life-table extension of the Mantel-Haenszel statistics with stratification for aspirin use.
Additional analysis will be performed for the primary endpoint to adjust for the baseline prognostic factors and colon cancer/adenoma risk factors using, for example, proportional hazard model or logistic model.
|
Year 3 (cumulative for year one and year three)
|
Percentage of patients with adenomas, aspirin use at baseline, and covariates
Time Frame: Year 5
|
This will be derived by treatment group (celecoxib 400 mg bid, celecoxib 200 mg bid, or placebo) and low-dose aspirin use at baseline and in relationship to the patient's adenoma history at the year 3 colonoscopy.
Of particular interest is whether the conditional rate of adenomas at year 5 differs by treatment group and strata with control for potential differences in these groups by adenoma history at year 3 colonoscopy, age, sex, family history of colorectal cancer, smoking, concomitant use of NSAID's, total time on study drug, and other covariates.
|
Year 5
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The number of adenomas identified per patient
Time Frame: Year 1
|
Will be compared between the Celecoxib treated arm and the Placebo treated arm using nonparametric analogs of the t-test (Wilcoxon rank sum or similar statistics).
Poisson regression will also be used to assess whether the number of adenomas detected at surveillance colonoscopy differs between the celecoxib and placebo groups.
|
Year 1
|
The number of adenomas identified per patient
Time Frame: Year 3
|
Will be compared between the Celecoxib treated arm and the Placebo treated arm using nonparametric analogs of the t-test (Wilcoxon rank sum or similar statistics).
Poisson regression will also be used to assess whether the number of adenomas detected at surveillance colonoscopy differs between the celecoxib and placebo groups.
|
Year 3
|
The highest histopathologic grade, largest size, and polyp burden (sum of the polyp diameters) of the colorectal adenomas
Time Frame: Up to 3 years
|
Will be analyzed using ordinal categorical data analysis methods.
|
Up to 3 years
|
The number of advanced adenomas (adenoma of size 1.0 cm or larger, any villous histology, high grade dysplasia, or invasive cancer) detected at surveillance
Time Frame: Up to 3 years
|
Up to 3 years
|
|
Adenoma findings at year 1 colonoscopy as predictors of adenoma findings at year 3 colonoscopy
Time Frame: Year 3
|
The findings of the Year 1 surveillance colonoscopy will also be evaluated as whether they can be used in future studies as a surrogate endpoint for the primary outcomeof the cumulative percentage of patients with newly detected adenomas at either the year one and/or at the Year 3 colonoscopy surveillance.
|
Year 3
|
Adverse events will be coded using the MedRA dictionary
Time Frame: Up to 3 months post-treatment
|
The safety analyses will consist of displays of the distribution by treatment group and adverse event category of the numbers of subjects reporting at least one episode of a specific adverse event (incidence table) and the severity and attribution to study drug of each episode reported (severity and attribution table).
The proportion of subjects withdrawn due to adverse events will also be summarized.
|
Up to 3 months post-treatment
|
Mean number of adenomas detected at year 5, as well as the distribution of number of adenomas, and the adenoma burden based on the sum of the adenoma diameters at year 5
Time Frame: Year 5
|
Year 5
|
|
Adverse events coded using the MedRA dictionary
Time Frame: Up to 5 years
|
Up to 5 years
