Evaluating guselkumab for treating fistulizing perianal Crohn's disease

A Phase 3, Randomized, Placebo-controlled, Parallel-group, Multicenter Study to Evaluate the Efficacy and Safety of Guselkumab in Participants With Fistulizing, Perianal Crohn's Disease

Phase 3 Interventional Janssen-Cilag Ltd. · NCT05347095

This study is testing if a new medication called guselkumab can help people with Crohn's disease who have painful perianal fistulas feel better compared to a placebo.

What this trial studies

This study aims to assess the effectiveness and safety of guselkumab in patients suffering from fistulizing, perianal Crohn's disease. Participants must have a confirmed diagnosis of Crohn's disease with at least one active draining perianal fistula. The study will compare the effects of guselkumab against a placebo to determine its clinical efficacy. Eligible patients include those who have not responded to or are intolerant to certain advanced drug therapies for Crohn's disease.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with Crohn's disease for at least three months and have at least one active draining perianal fistula.

Not a fit: Patients with very severe luminal disease activity or those with specific concurrent fistula types may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of fistulizing perianal Crohn's disease, offering relief to patients with limited options.

How similar studies have performed: Other studies have shown promise with similar biologic therapies for Crohn's disease, indicating potential for success with this approach.

* Must have a diagnosis of Crohn's disease with a minimum duration of at least 3 months
* Has at least one active draining perianal fistula as a complication of Crohn's disease, confirmed by screening magnetic resonance imaging (MRI) results
* Has previously demonstrated lack of initial response (that is primary non-responders), responded initially but then lost response with continued therapy (that is secondary non-responders), or were intolerant to a maximum of 2 classes of advanced drug therapies at a dose approved for the treatment of Crohn's disease (that is infliximab, adalimumab, certolizumab pegol, vedolizumab, or approved biosimilars for these agents) or JAK inhibitors licensed for Crohn's disease treatment (that is, upadacitinib)

Exclusion Criteria:

* Has a very severe luminal disease activity
* History of concurrent rectovaginal fistulas (other types of concurrent fistula should be confirmed with the sponsor), rectal and/or anal stenosis, stoma or functioning ostomy (include all current stoma types abscess or collections which are not properly drained) colonic mucosal dysplasia or pre-cancerous lesions that have not been removed, demyelinating disease, or systemic lupus erythematosus
* Has complications of CD, such as symptomatic strictures or stenoses, short gut syndrome, or any other manifestation that might be anticipated to require surgery or preclude fistula evaluation
