About This Trial

Researchers want to learn more about tulisokibart (also known as MK-7240) in an extension study. Tulisokibart is a medicine designed to treat active, moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). An extension study is a type of study where people who received tulisokibart in certain other studies for CD or UC (called a parent study) may be able to join this study. The goals of this study are to learn about the safety of tulisokibart over time in people with CD or UC, and if people tolerate it.
