CAMBRIDGE, MA, USA I January 3, 2019 I Seres Therapeutics, Inc. (Nasdaq:MCRB) today announced that it has enrolled the first patient in its Phase 2B trial, ECO-RESET, evaluating microbiome development candidate SER-287 in patients with active mild-to-moderate ulcerative colitis. Seres has received $40 million in milestone payments associated with this study start from Nestlé Health Science.
“Advancing SER-287 into a late stage Phase 2B trial is a significant achievement,” said Kevin Horgan, M.D., Executive Vice President and Chief Medical Officer. “We are hopeful that SER-287 may provide individuals with ulcerative colitis with a novel microbiome-based, non-immunosuppressive therapy that addresses the underlying pathology of this serious disease. If this study is successful, we believe the trial results could provide important support for registration of SER-287.”
The SER-287 Phase 2B ECO-RESET study has been designed as a pivotal trial. The Company recently obtained feedback from the FDA indicating that results from this study, in conjunction with data from a second pivotal study, could enable a SER-287 Biologics License Application.
The Phase 2B study is a three-arm placebo-controlled trial of approximately 200 patients with active mild-to-moderate ulcerative colitis. Two groups of patients will receive different doses of SER-287, both following pretreatment with a short course of oral vancomycin. A third study arm will receive placebo. The study’s primary endpoint will evaluate clinical remission measured after 10 weeks of SER-287 administration. Endoscopic improvement will be measured as a secondary efficacy measure.
SER‐287 is a biologically sourced oral capsule developed using Seres’ proprietary microbiome therapeutics platform. The SER-287 Phase 2b study clinicaltrials.gov identifier is NCT03759041. A SER-287 Phase 1b placebo-controlled induction study in patients with mild-to-moderate active ulcerative colitis demonstrated a dose-dependent improvement of clinical remission rates and endoscopic scores and a favorable tolerability profile.

Ulcerative colitis is a serious chronic condition affecting approximately 700,000 individuals in the United States. The disease results in inflammation of the colon and rectum and can cause debilitating symptoms, including abdominal pain, bowel urgency and diarrhea.
