What this trial studies

This observational study aims to monitor adult patients in South Korea who are being treated with subcutaneous vedolizumab for moderate to severe ulcerative colitis or Crohn's disease. Participants will have previously experienced inadequate responses or intolerable side effects from conventional therapies or TNF-α antagonists. The study will collect data from medical records over approximately six years to evaluate the safety and effectiveness of vedolizumab in a real-world clinical setting. The study will enroll around 600 participants and will focus on understanding the treatment's impact on these conditions.
