How well does this medication work for Crohn's disease?

This trial is observing how well Ustekinumab works for people with Crohn's disease. Researchers will look at both past medical records and collect new information going forward to understand how effective this medication is at helping patients feel better and manage their condition.

Doctors need real-world evidence about how this medication performs in everyday clinical practice—not just in controlled research settings—so they can better understand which patients benefit most from the treatment.
