Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for certified medical advice, calls or professional assistance using a genuine dr.. We aren't physicians. Always confer with your dr. on Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer Clinical research trials and Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer medical trials happen in hundreds of localities throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically measure the effectualness of new does drugs. The intent of the studies / undertakings is to answer particular human health questions. Clinical trials are a popular manner for physicians, government agencies, and private sector corporations to find cures for all kinds of circumstances, like Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer. Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer Clinical Trials and other clinical trials permit volunteers to acquire healthcare treatment options before they are available to the general public. Some times the subjects acquire professional assistance for free, and sometimes they are paid for their time. Sometimes there is a cost for a Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer clinical trial. Participants frequently obtain the most expert healthcare available for their Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer condition. Dangers are a reality, nevertheless, and can include more or frequent doctor calls, health risks (potentially life-jeopardizing), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials subjects.

Comparison of Sulindac, Aspirin, and Ursodiol in Preventing Colorectal Cancer
For Condition: stage 4 colon cancer,stage 2 colon cancer,stage 3 colon cancer,stage 1 colon cancer,Colorectal Cancer
Status: Recruiting
Sponsor(s): M.D. Anderson Cancer Center , National Cancer Institute (NCI)
Synopsis: RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. It is not yet known whether sulindac, aspirin, or ursodiol is more effective in preventing colorectal cancer. PURPOSE: Randomizedphase II trial to compare the effectiveness of sulindac, aspirin, and ursodiol in preventing colorectal cancer.
Details: OBJECTIVES: - Determine the percentage change in colorectal aberrant crypt foci (ACF) in patients with a history of colorectal cancer or at high risk for colorectal cancer when treated with sulindac vs aspirin vs ursodiol. - Determine the safety and efficacy of these drugs, in terms of ability to cause regression of existing colorectal ACF and prevent new ACF development, in these patients. OUTLINE: This is a partially blinded, randomized, placebo-controlled study. Patients are stratified according to colorectal neoplasia (adenoma vs carcinoma). Patients are randomized to 1 of 4 treatment arms. - Arm I: Patients receive oral sulindac twice daily. - Arm II: Patients receive oral aspirin once daily. - Arm III: Patients receive oral ursodiol three times daily. - Arm IV: Patients receive oral sulindac placebo twice daily. In all arms, treatment continues for 12 months in the absence of disease progression or unacceptable toxicity. Patients undergo a colonoscopy at baseline and at the end of treatment. Patients are followed at 2 months after the end of treatment. PROJECTED ACCRUAL: A total of 172 patients (43 per treatment arm) with a history of colorectal cancer or adenomas will be accrued for this study. A total of 20 additional patients with no elevated risk of colorectal neoplasia will be accrued, but not randomized, for this study.
