Inflammatory bowel disease (IBD) is a chronic, relapsing remitting inflammatory disease of the intestine. The two main forms of IBD are Crohn's disease (CD) and Ulcerative Colitis (UC). There is no cure for IBD and the etiology is unknown, however IBD is thought to arise as an aberrant immune response to the intestinal microbiota. The intestinal microbiota closely correlates with inflammation in IBD. Currently, the treatment of IBD is based on suppressing the aberrant immune response in the intestine. This often takes the form of systemic immunosuppression, which in turn carries a multitude of risks including infection and malignancy. Thus there is an urgent need for safe, effective therapies that ultimately have the potential to cure IBD.
Fecal microbiota transplantation (FMT) is the process of transferring fecal microbiota from one individual to another. FMT has revolutionized the treatment of multiple recurrent Clostridium difficile infection with a cure rate around 90%. Given the success of FMT in C. difficile colitis, attention turned to other forms of colitis, in particular IBD. Early pilot studies demonstrated a mixed result for the use of FMT in IBD. One of the key issues surrounding the use of FMT in IBD is the challenge of engrafting a new microbiota. Additionally IBD flares following FMT for C. difficile infection have been reported, although it is difficult to account for the confounding of the underlying C. difficile infection. This study will examine how FMT donor selection can impact the engraftment of the microbiota into patients with UC.

Active Comparator: FMT Treatment
Fecal microbiota - 1.0-3.0 x 10^11 CFU / day (2 capsules per day for 8 weeks).
Drug: Fecal microbiota
Lyophilized encapsulated fecal microbiota given daily for 8 weeks.
Placebo Comparator: Placebo
The placebo consists of a mixture of trehalose and crystalline methylcellulose (Avicel) in 6:1 (w/w) ratio that is packaged in size 0 swedish orange capsules, which are then double encapsulated in size 00 natural colored capsules to make them visibly indistinguishable from encapsulated active product. Two capsules taken daily for 8 weeks.
Placebo capsules identical in appearance to fecal microbiota capsules to be taken daily for 8 weeks.
- Engraftment of low sulfate reducing microbiota [ Time Frame: 12 weeks ]Change in quantitative PCR of sulfate reducing genes from baseline to week 12 between FMT arm and placebo arm.
- Rate of change of sulfate reducing microbiota [ Time Frame: 4 weeks ]Change in quantitative PCR of sulfate reducing genes at week 1, 2, 3 and 4 between FMT arm and placebo arm
- Clinical efficacy of FMT versus placebo [ Time Frame: 8 weeks ]Change in partial Mayo score from baseline to week 8 between FMT and placebo arm
- Clinical efficacy of low sulfate reducing microbiota [ Time Frame: 12 weeks ]Partial mayo score at week 12 between those with low sulfate reducing microbiota or not low sulfate reducing microbiota
- Serious adverse events [ Time Frame: 12 weeks ]Number of serious adverse events between FMT arm and placebo arm
