Transfer of Feces in Ulcerative Colitis 2

Transfer of Feces in Ulcerative Colitis 2; Improving Efficacy

The goal of this placebo-controlled randomised multicenter trial is to evaluate the efficacy and safety of anaerobic prepared donor fecal microbiota transplantation (FMT) compared to autologous FMT in patient with ulcerative colitis.

Participants will receive 4 treatments with frozen FMT via both upper and lower gastro-intestinal route (infusion via duodenal tube and enemas).

Donors are selected based on microbiota profile.
