This clinical trial is focused on studying ulcerative colitis, a condition that causes inflammation and sores in the lining of the large intestine. The study will compare two treatments: vedolizumab and infliximab. Vedolizumab is a medication that is not yet registered for use in children, while infliximab is a standard treatment. Both medications are given through an infusion, which means they are administered directly into the bloodstream through a vein.
The purpose of the study is to assess the safety and effectiveness of these treatments in children aged 6 to 17 years who have ulcerative colitis. Participants will be randomly assigned to receive either vedolizumab or infliximab. The study will be conducted in a way that neither the participants nor the researchers know which treatment is being given, a method known as “double-blind.” This helps ensure that the results are not biased. The study will also include a comparison with a placebo to better understand the effects of the treatments.
Throughout the study, the safety of the treatments will be closely monitored by tracking any side effects that occur. The effectiveness will be measured by observing changes in the symptoms of ulcerative colitis, such as improvements in inflammation and overall health. The study aims to provide valuable information on how these treatments work in children and to determine which treatment might be more beneficial for managing ulcerative colitis in this age group.
