Summary
This study looks at the long-term safety of the drug ustekinumab compared to other biologic treatments in adults with Crohn's disease or ulcerative colitis. Researchers will use health records from the Department of Defense to track rates of cancer, serious infections, and other risks. About 1,056 participants who are new users of these drugs will be followed to see how safe they are over time.
