When you are considering participation in a clinical trial, it is important to understand what will be expected of you before, during, and after the trial. Visit the "What to Expect" page on this website for general information.

For clinical trials of Crohn’s Disease and Ulcerative Colitis, you will probably need to visit the research doctor more often than you do for your normal care. These frequent visits may go on for a year or more. During the clinical trial, you will have several types of assessments, such as stool samples, patient-reported outcomes, and colonoscopy. Please note that the procedures for a specific study may differ from this list, so be sure to follow the instructions provided by your research doctor.
