NCT04997733

Brief Summary

Crohn's disease (CD) is a chronic inflammatory bowel disease. CD pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota in predisposed hosts. The purpose of this study is to evaluate de clinical efficacy of the fecal microbiota transplantation (FMT) as a maintenance treatment following anti-TNF agent withdrawal in CD's patient.

Outcome Measures

Primary Outcomes (1)

  • Evaluate the clinical efficacy of FMT versus sham transplantation as a maintenance treatment following anti-TNF agent withdrawal in patients with Crohn's disease in steroid-free clinical remission for at least 6 months under anti-TNF agent

    Clinical remission (defined by a Crohn's disease activity index (CDAI) \<150) at week 52 (V8) without any flare between week 0 (colonoscopy (V2)) and week 52 (V8). Flare is defined by a CDAI (Addendum 2) above 250 or between 150 points and 250 points with a 70-point increase from baseline over 2 consecutive weeks and the need

    52 weeks after FMT or sham-transplantation

Secondary Outcomes (1)

  • Relapse free survival

    52 weeks after FMT or sham-transplantation

Other Outcomes (7)

  • Mucosal healing

    52 weeks after FMT or sham-transplantation

  • Clinical remission

    52 weeks after FMT or sham-transplantation

  • Endoscopic remission

    52 weeks after FMT or sham-transplantation

  • +4 more other outcomes

Study Arms (2)

Fecal microbiota

EXPERIMENTAL

Patients receiving the fecal microbiota transplantation (FMT) in 3 times after inclusion and randomisation (endoscopic and oral)

Drug: Fecal Microbiota Transplantation (FMT)

Sham-transplantation

SHAM COMPARATOR

Patients receiving the sham-transplantation in 3 times after inclusion and randomisation (endoscopic and oral)

Drug: Sham-transplantation (placebo)

Interventions

The colonoscopy for FMT will be planned between 7 and 14 days after the last adalimumab or sub-cutaneous infliximab administration and 6 weeks +/- 7 days after the last intravenous infliximab administration 14 and 28 days following the last sub-cutaneous golimumab administration. After colon cleansing using polyethylene glycol, the patient will have a colonoscopy under general anesthesia. The patient will then receive either FMT (frozen preparation of 50g of stools in 300ml of saline (NaCl 0.9%), (FMT vehicle in the terminal ileum or the colon. At W12 and W24 after first colonoscopy, the patient receives treatment by capsule (15 capsules contain 0.8g of stools by visit).

Fecal microbiota

The colonoscopy for sham-transplantation will be planned between 7 and 14 days after the last adalimumab or sub-cutaneous infliximab administration and 6 weeks +/- 7 days after the last intravenous infliximab administration, 14 and 28 days following the last sub-cutaneous golimumab administration. After colon cleansing using polyethylene glycol, the patient will have a colonoscopy under general anesthesia. The patient will then receive either sham transplantation (frozen preparation of NaCl 0.9% with 10% glycerol) in the terminal ileum or the colon. At S12 and S24 after first colonoscopy, the patient receives treatment by capsule (15 capsules contain placebo).
