Switching to subcutaneous infliximab for IBD treatment

Official title: Subcutaneous Infliximab After A Previous Intravenous Dose Optimization

Run by Belgian Inflammatory Bowel Disease Research and Development (BIRD) VZW · NCT06113913 · Data updated 2026-11-12

This study is testing if switching people with inflammatory bowel disease from an intravenous form of infliximab to a subcutaneous version, given weekly or bi-weekly, can lead to better health results.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a confirmed diagnosis of Crohn's disease, ulcerative colitis, or IBD unclassified who are in clinical remission without steroid use.

Probably not a fit

Patients who are not in remission or those who have not previously received intravenous infliximab may not benefit from this study.

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

What this trial studies

This clinical trial investigates the effectiveness of switching patients with inflammatory bowel disease (IBD) from intravenous infliximab to subcutaneous infliximab. Participants will be randomized to receive either a weekly or bi-weekly subcutaneous dose after previously optimized intravenous treatment. The study aims to determine if the weekly dosing leads to better clinical outcomes compared to the standard bi-weekly administration. Monitoring will focus on achieving clinical and biological remission throughout the trial.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for patients with IBD by optimizing the administration of infliximab.

How similar studies have gone: Previous studies have shown promising results with subcutaneous infliximab, but this specific approach of switching from intravenous to subcutaneous dosing is relatively novel.
