Official title: Fecal Microbiota Transplantation in Crohn's Disease as Relay After Anti-TNF Withdrawal
Run by Assistance Publique - Hôpitaux de Paris · NCT04997733 · Data updated 2026-11-12
This study is testing if a stool transplant can help keep people with Crohn's disease in remission after they stop using a certain medication.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 75 with Crohn's disease in steroid-free clinical remission for at least six months while on anti-TNF treatment.
✕Probably not a fit
Patients currently experiencing a flare of Crohn's disease or those who do not meet the inclusion criteria will not benefit from this study.

What this trial studies
This study evaluates the effectiveness of fecal microbiota transplantation (FMT) as a maintenance treatment for patients with Crohn's disease who are in remission after withdrawing from anti-TNF therapy. The trial aims to restore a healthy gut microbiota in patients whose condition is characterized by an inappropriate immune response and altered gut microbiota. Participants will receive either FMT or a sham treatment to assess the clinical outcomes over a specified period. The study is designed to address the lack of specific recommendations for Crohn's disease patients in remission under anti-TNF agents.
Why it matters
Potential benefit: If successful, this approach could provide a new maintenance treatment option for Crohn's disease patients, potentially improving their quality of life and reducing reliance on immunosuppressive therapies.
How similar studies have gone: While previous studies have explored fecal microbiota transplantation for other conditions, randomized controlled trials specifically for Crohn's disease are lacking, making this approach relatively novel.
