Study Summary:

The purpose of the study is to evaluate the efficacy and safety of a new investigational mesalamine (5-ASA) 1 g suppository (study medication) as compared to placebo in adults with mild to moderate ulcerative colitis (disease located in the rectum). Patients found to be eligible will be randomized to receive either the medication, Canasa 1g suppositories or, Placebo suppositories once daily at bedtime for 6 weeks. Upon completion of the first six weeks of investigational treatment you will be given the opportunity to receive the study medication on a voluntary basis for the next 8 weeks of the study depending on the evaluation of the severity of your disease by the study medical doctor at Week 6. Regardless of the study groups all patients will be evaluated through phone calls at Study Weeks 1 and 2 followed by clinical visits at Study Weeks 3, 6, and 14. A total of 5 clincial visits are planned over a period of 16 weeks. Study-specific procedures include but are not limited to the following: flexible proctosigmoidoscopy (visualization of the interior of the rectum) with or without tissue sampling; disease activity assessment; health-related quality of life assessment; compliance to treatmentcheck and safety evaluations.
