RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of nitric oxide-releasing acetylsalicyclic acid may prevent colorectal cancer.
PURPOSE: This randomized phase I trial is studying the side effects and best dose of nitric oxide-releasing acetylsalicyclic acid in preventing colorectal cancer in patients at high risk of colorectal cancer.
|Condition or disease||Intervention/treatment||Phase|
|Colorectal Cancer||Drug: nitric oxide-releasing acetylsalicylic acid derivative Other: laboratory biomarker analysis Procedure: biopsy||Phase 1|
- Evaluate the effects of nitric oxide-releasing acetylsalicyclic acid on aberrant cryptic foci (ACF) in patients at high risk for colon cancer.
- Determine the pharmacokinetic profile of this drug in these patients.
- Determine the presence or absence of ACF in these patients.
- Determine the expression of PGE2, COX-1, COX-2, NF-kB, and β-catenin in colon tissue.
- Determine the safety and tolerability of long-term nitric oxide-releasing acetylsalicyclic acid in these patients.
OUTLINE: This is a multicenter, double-blind, randomized, placebo-controlled, parallel group study. Patients are stratified according to gender and race (black vs non-Hispanic white vs Hispanic white vs Asian). Patients are randomized to 1 of 3 treatment arms.
- Arm I: Patients receive oral nitric oxide-releasing acetylsalicyclic acid twice daily for 6 months.
- Arm II: Patients receive nitric oxide-releasing acetylsalicyclic acid twice daily for 6 months at a higher dose than in arm I.
- Arm III: Patients receive oral placebo twice daily for 6 months. Patients undergo sigmoidoscopies at baseline and at the completion of study treatment. Biopsies of aberrant cryptic foci (ACF) and non-ACF sites are collected at both sigmoidoscopies. Tissue is examined for biomarkers (PGE_2, COX, NF-kB, β-catenin).
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study.
