Why This Matters

Perianal fistulas are a serious, hard-to-treat complication of Crohn’s disease. Evidence that guselkumab (Tremfya) can sustain fistula remission through 48 weeks could expand treatment options for people with fistulizing Crohn’s disease.

Who Should Pay Attention

Adults with Crohn’s disease (especially those with perianal fistulas), IBD clinicians, and researchers focused on fistulizing disease or biologic therapies.

What To Know

The FUZION trial evaluated guselkumab (Tremfya) in patients with perianal fistulizing Crohn’s disease and measured combined fistula remission using clinical and radiologic assessments.

At Week 24, Tremfya showed a statistically evaluated benefit versus placebo; the company reports that remission rates were maintained or improved at Week 48 with both 100 mg every eight weeks and a higher maintenance 200 mg every four weeks regimen.

The longer-term safety through 48 weeks was consistent with the established profile and no new safety concerns were reported in the company release.

The reported results are from a company press release presented at UEG Week and describe extension outcomes through 48 weeks; the 48-week comparisons reported here do not include a new placebo-controlled comparison in the company summary. The study population included patients with prior biologic exposure as well as biologic-naïve patients.

Keep In Mind

Results were presented by the company at UEG Week and come from the Phase 3 FUZION trial. The 48-week figures reported do not include a new placebo-controlled comparison in the company summary; await full peer-reviewed publication or regulatory disclosures for complete data and safety details.
