This study is for adults with Inflammatory Bowel Disease (IBD), like Crohn's Disease and Ulcerative Colitis. We are checking how safe and effective some new treatments are. Crohn's Disease and Ulcerative Colitis cause inflammation in the digestive tract, leading to pain and other issues. We use tests called endoscopy (a camera check inside the body) and histopathology (studying tissue under a microscope) to confirm the disease. This study will look at how the body absorbs (pharmacokinetics) and responds to (pharmacodynamics) the treatments, which could be pills or shots. Participants need certain disease activity levels and stable medication use to join.

• Duration: The study has specific phases, but exact length varies.
• Visits: Multiple visits for check-ups and tests are required.
• Risks: Some past surgeries or recent severe conditions may exclude you.
