Official title: A Prospective Observational Study on the Efficacy and Safety of Guselkumab in the Treatment of Crohn's Disease Patients Previously Treated With Ustekinumab

Run by Second Affiliated Hospital, Zhejiang University, School of Medicine · NCT07487480 · Data updated 2026-11-12

This study will try guselkumab for adults with moderate to severe Crohn's disease who did not respond to or could not tolerate ustekinumab to see if they reach remission after 52 weeks.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with a Crohn's disease diagnosis of at least 3 months, moderate to severe activity (CDAI 220–450), and prior documented primary non-response, secondary loss of response, or intolerance to ustekinumab are eligible.

Probably not a fit

Patients previously treated with any anti‑IL‑23p19 therapy (including guselkumab), those with active intestinal infections, obstructive lesions, recent abscess, certain serious infections or malignancies, or who are pregnant/lactating are excluded and unlikely to benefit from this protocol.

What this trial studies

This is a prospective, single-center, observational study enrolling about 60 adults (18–75 years) with moderate to severe Crohn's disease who previously failed or were intolerant to ustekinumab. Participants will receive guselkumab following a defined induction and maintenance dosing schedule and will be followed for 52 weeks. The primary outcome is the proportion of patients achieving clinical remission at Week 52, with secondary endpoints including clinical response, endoscopic improvement, biomarker changes, quality of life, and safety. The study collects real-world effectiveness and safety data in the specific population of ustekinumab-experienced patients.

Why it matters

Potential benefit: If successful, the study could show that guselkumab helps patients who failed ustekinumab achieve remission and better quality of life.

How similar studies have gone: Guselkumab has shown efficacy in biologic‑naïve and some TNF‑antagonist–failed Crohn's disease populations in prior studies, but prospective data specifically in patients who failed ustekinumab are limited.
