Seres Therapeutics Announces Achievement of Target Enrollment in SER-287 Phase 2b ECO-RESET Study for Ulcerative Colitis
- Topline clinical data expected in mid-2021 -
- Results will inform Seres’ broader development efforts in UC and other programs targeting modulation of host inflammation and immunity -
“People with ulcerative colitis and other inflammatory bowel diseases are in need of safe and effective treatment options, especially for mild-to-moderate forms of the disease. ECO-RESET achieved its target enrollment even amid the ongoing COVID-19 pandemic, a reflection of this high unmet need,” said
The Phase 2b ECO-RESET study (Clinicaltrials.gov identifier: NCT03759041) is a multicenter, randomized, placebo-controlled study which has enrolled the targeted 201 patients with active mild-to-moderate UC. Two groups of patients are receiving different doses of SER-287, both following pre-conditioning with a short course of oral vancomycin. A third group is receiving 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.
Based upon feedback obtained from the
Mild-to-moderate UC is the most common form of the disease, representing a majority of the patient population in the
“Seres is grateful to the patients, principal investigators and clinical research teams who have made this study possible. Their commitment to the trial’s successful execution despite the challenges of COVID-19 has been remarkable,” said
SER-287, an oral microbiome therapeutic candidate consisting of a consortium of highly purified Firmicute spores, is designed to normalize the gastrointestinal microbiome of individuals with UC. Preclinical colitis animal models and in vitro screens provide evidence that SER-287 administration has the potential to reduce pathology and modulate inflammatory and immunological functional pathways. SER-287 has been granted Fast Track Designation by the FDA for the induction and maintenance of clinical remission in adult subjects with active mild-to-moderate UC. SER-287 has been designated an Orphan Drug for pediatric UC by the FDA.
