Primary Outcome Measures:
  • Safety and tolerability of SER-287 vs. placebo in adult subjects by analysis of AE's, lab values, vital sign, physical exam findings, medical history, and ECG. [ Time Frame: Day 246 ]
  • Examination of baseline composition of the intestinal microbiome to the composition [ Time Frame: 8 weeks ]
    Changes in the composition of the microbiome will be characterized by rDNA 16S V4 genomic data sets. Changes will be assessed by total number of unique bacteria and microbial composition

  • Engraftment of SER-287 bacteria into the intestinal microbial community in each of the SER-287 arms compared to the placebo arm [ Time Frame: 8 weeks ]
    Microbiome will be characterized by rDNA 16S v4 Genomic Data Sets. Engraftment will be assessed as the outgrowth of bacteria that compromise the SER-287 spore ecology in the subjects GI tract post treatment

Detailed Description:
This is a Phase 1b multicenter, randomized, double-blind, placebo-controlled multiple dose study designed to evaluate the safety and tolerability of SER-287, and to evaluate the microbiome alterations and pharmacodynamics associated with 2 dosing regimens of SER-287 in adult subjects with mild-to-moderate ulcerative colitis (UC).

Inclusion Criteria:

  • Ulcerative colitis diagnosed by routine clinical, radiographic, endoscopic and pathologic criteria (preferably confirmed by colonoscopy and pathology records within last 2 years or if unavailable, will need approval by medical monitor) Active mild-moderate UC as determined by sigmoidoscopy within approximately 3 days of randomization to study

  16. Received an investigational antibody or vaccine within 3 months before study entry
  17. Previously enrolled in a SER-109/SER-287 study
  18. Received an FMT within the last 6 months
  19. Subjects with anatomic or medical contraindications to flexible sigmoidoscopy, including but not necessarily limited to toxic megacolon, gastrointestinal (GI) fistulas, immediate post-operative status from abdominal surgery, severe coagulopathy, large or symptomatic abdominal aortic aneurysm, or any subject where study physician deems subject at significant risk of complications of flexible sigmoidoscopy
