Phase III Randomized Study of Celecoxib for Prevention of New Sporadic Adenomatous Colorectal Polyps in Patients Who Have Undergone Polypectomy
Alternate Title Celecoxib to Prevent Colorectal Cancer in Patients Who Have Undergone Surgery to Remove Polyps
Objectives I. Determine the safety and efficacy of celecoxib in reducing the occurrence of new sporadic adenomatous polyps (SAP) in the colon and rectum in patients who have undergone polypectomy for previous SAP. Entry Criteria Disease Characteristics: At least one prior colorectal adenomatous polyp removed by polypectomy within the past 5 months and meeting any of the following criteria: One adenomatous polyp at least 6 cm in size Two or more adenomatous polyps of any size One adenomatous polyp and a documented history of adenomatous polyps No history of familial polyposis or hereditary nonpolyposis colorectal cancer No history of inflammatory bowel disease Prior/Concurrent Therapy: Biologic therapy: Not specified Chemotherapy: Not specified Endocrine therapy: At least 2 months since prior oral corticosteroids received 3 or more times per week At least 6 months since prior oral or intravenous corticosteroids received for more than 2 weeks duration No anticipated oral or intravenous corticosteroid use of more than 2 weeks duration over the next 6 months At least 6 months since prior inhaled corticosteroids received for more than 4 weeks duration No anticipated inhaled corticosteroid use of more than 4 weeks duration over the next 6 months Use of mometasone (Nasonex) is not restricted (all other nasal steroids are prohibited) Radiotherapy: Not specified Surgery: No prior large bowel resection other than appendectomy Other: At least 1 month since any prior treatment for gastrointestinal ulcer At least 2 months since prior nonsteroidal anti-inflammatory drugs (NSAIDS), other than aspirin, received 3 or more times per week No concurrent chronic NSAIDS, defined as a frequency of 1-week (7 consecutive days) for more than 3 weeks per year At least 1 month since prior investigational medications No other concurrent investigational drugs No concurrent fluconazole or lithium Patient Characteristics: Age: 30 and over Performance status: Not specified Life expectancy: Not specified Hematopoietic: Not specified Hepatic: No chronic or acute hepatic disorder Renal: No chronic or acute renal disorder Other: No prior participation in this study No significant bleeding disorder or other condition that would preclude study therapy No history of hypersensitivity to COX-2 inhibitors, NSAIDS, salicylates, or sulfonamides No prior invasive cancer within the past 5 years other than nonmelanomatous skin cancer Fertile patients must use effective contraception Expected Enrollment Over 1000 patients will be accrued for this study. Outline This is a randomized, double blind, placebo controlled study. Patients are entered on one of two treatment arms: Arm I: Patients receive celecoxib twice a day for 3 years. Arm II: Patients receive placebo twice a day for 3 years. Patients are evaluated for adenomatous colorectal polyps at 1 and 3 years.Published Results Bertagnoli MM, Eagle CJ, Hawk ET: Celecoxib reduces sporadic colorectal adenomas: results from the Adenoma Prevention with Celecoxib (APC) trial.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. |
