Guselkumab for Chinese patients with moderate-to-severe ulcerative colitis in routine care

Guselkumab Real-world Effectiveness Among Bio-NaÏve Patients With Moderate-to-severe Ulcerative Colitis in China: A Multicenter, Non-interventional, Prospective Study

Observational Xian-Janssen Pharmaceutical Ltd. · NCT07302360

This project will try guselkumab in Chinese adults with moderate-to-severe ulcerative colitis who have never used biologic therapies to see how their symptoms, endoscopic appearance, and quality of life change in routine clinical care.

What this trial studies

This observational, real-world study follows biologic‑naive Chinese participants with moderate-to-severe ulcerative colitis who start guselkumab as part of routine care. Eligible participants have a modified Mayo score of 4–9, endoscopic Mayo subscore ≥2, and rectal bleeding subscore ≥1 at baseline, and they initiate treatment per their physician's decision. Clinical outcomes, endoscopic findings, patient-reported function and quality-of-life measures, and routine safety data will be collected from medical records and clinic visits. The study aims to characterize the effectiveness and tolerability of guselkumab in everyday clinical practice in this population.

Who should consider this trial

Good fit: Ideal candidates are Chinese adults with moderately to severely active UC (modified Mayo 4–9, endoscopic subscore ≥2, rectal bleeding subscore ≥1) who are biologic‑naive and are starting guselkumab under their physician's care.

Not a fit: Patients with prior exposure to biologic or other advanced therapies, those with acute severe ulcerative colitis, or those not initiating guselkumab per physician decision are unlikely to benefit from this observational project.

Why it matters

Potential benefit: If successful, the results could support guselkumab as an effective option to reduce symptoms, promote mucosal healing, and improve quality of life for biologic‑naive Chinese UC patients.

How similar studies have performed: IL‑23 pathway therapies and some guselkumab trials have shown promise in inflammatory bowel disease, but real‑world data specifically in Chinese biologic‑naive UC patients remain limited.
