This clinical trial is focused on studying two diseases: Ulcerative Colitis and Crohn’s Disease. These are conditions that cause inflammation in the digestive tract, leading to symptoms like abdominal pain and diarrhea. The treatment being studied is called Vedolizumab, which is a medication designed to help reduce this inflammation. In this study, Vedolizumab will be given in two forms: as a solution for infusion, which is administered through a vein, and as a solution for injection, which is given under the skin using a pre-filled syringe.
The purpose of the study is to evaluate how the body processes Vedolizumab when given as an injection in children who have shown improvement after receiving the medication through an infusion. The study will involve children with moderate to severe forms of Ulcerative Colitis or Crohn’s Disease. Participants will first receive Vedolizumab through an infusion to see if they respond positively. Those who do will then continue to receive the medication as an injection for a period of time. The study will monitor the safety of the medication and how the body reacts to it over time.
Throughout the study, researchers will collect information on how the medication is absorbed and processed in the body, as well as any potential immune responses to the treatment. This information will help determine the best way to use Vedolizumab in treating these conditions in children. The study aims to provide valuable insights into the effectiveness and safety of Vedolizumab for young patients with these inflammatory bowel diseases.
