Is this trial a fit for you?

Likely a good fit

Adults with a confirmed diagnosis of moderate-to-severe ulcerative colitis or Crohn's disease who are eligible for and starting guselkumab per their physician, can consent, and have not previously received IL-23 inhibitors are ideal candidates.

Probably not a fit

Patients who are contraindicated to guselkumab, already treated with IL-23 inhibitors, or currently enrolled in an interventional trial are unlikely to be eligible or to benefit from this observational data.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational registry will follow adults in the UK who start guselkumab for moderate-to-severe ulcerative colitis or Crohn's disease, with enrollment before or at first dose per the treating physician's decision. Data will be collected from medical records to describe clinical outcomes by line of therapy and in predefined subpopulations while excluding patients previously treated with IL-23 inhibitors. No treatment is assigned by the protocol and patients receive care according to local NHS guidance, with source data verification performed after informed consent. The sponsor is Janssen-Cilag Ltd. and the initial site listed is London North West University Healthcare NHS Trust.

Why it matters

Potential benefit: If successful, this could show how guselkumab performs in everyday NHS practice and help doctors choose which patients may benefit.

How similar studies have gone: Other IL-23 inhibitors such as risankizumab and mirikizumab have shown efficacy in trials for IBD, but real-world data specifically for guselkumab in UC and Crohn's disease remain limited.
