Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts.

The purpose of this study is to determine the effect of the fecal microbiota transplantation on UC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease affecting approximately 90 000 patients in France, mostly at young age, and altering their quality of life.

Conventional Immunosuppressive treatment (ie azathioprine, anti-TNF (tumor necrosis factor ), vedolizumab) used in UC are expensive and associated with potentially severe complications such as infections and cancers.

UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts.

Fecal microbiota transplantation (FMT) is now recommended in guidelines for treating recurrent Clostridium difficile infection. Although the pathogenesis involved in UC is different, FMT is a potential therapeutic strategy as transferring a healthy microbiota in an UC patient could restore the appropriate host-microbiota crosstalk.

As the gut microbiota is dramatically altered by intestinal inflammation, transferring a massive amount of microbial organisms in an inflamed gut with epithelial barrier disruption might be a suboptimal strategy and could even have detrimental effects by allowing bacterial translocation.

Thus, it's possible that performing FMT in UC patients who achieved remission after conventional treatment might be associated with better clinical outcome than in patients with active disease.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group B - fecal microbiota transplantation

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

Group Type EXPERIMENTAL

Fecal Microbiota Transplantation (FMT)

Intervention Type DRUG

The colonoscopy for FMT will be planned as soon as possible and never more than 5 weeks after inclusion visit.

After colon cleansing using Polyethylen 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 physio, see donor section for details) or sham transplantation (FMT vehicle) in the cecum.

Group A- Sham-transplantation

Patients receiving the sham-transplantation in 3 times after inclusion and randomisation

Group Type PLACEBO_COMPARATOR

Sham-transplantation Placebo

Intervention Type DRUG

The sham-transplantation will be planned as soon as possible and never more than 5 weeks after inclusion visit.

After colon cleansing using Polyethylen glycol, the patient will have a colonoscopy under general anesthesia.

The patient will then sham transplantation (FMT vehicle) in the cecum.
