Is this trial a fit for you?

Likely a good fit

Adults with confirmed moderate-to-severe Crohn's disease or ulcerative colitis who are starting guselkumab under approved indications and consent to participate.

Probably not a fit

Patients who do not respond to guselkumab or discontinue early for reasons unrelated to treatment persistence may not benefit from findings.

What this trial studies

This observational study follows patients with moderate-to-severe Crohn's disease or ulcerative colitis who start guselkumab to see how long they continue the treatment in typical clinical settings. It uses real-world data to assess treatment persistence and adherence to the prescribed plan. Enrolment occurs at or before the first gab of dosing, with physicians deciding eligibility according to current labeling. The analysis will focus on patients seen at the Medical University of Vienna and may inform persistence patterns in everyday practice. No interventional procedures are described beyond routine guselkumab administration.

Why it matters

Potential benefit: If successful, the study could clarify how well patients adhere to guselkumab in real-world care, potentially guiding future treatment decisions.

How similar studies have gone: Previous real-world studies of similar biologics have shown variable persistence, suggesting this approach could yield meaningful insights but may be limited by observational design.
