Seres Therapeutics to Host Virtual SER-109 Focused Symposium on May 27, 2020, Ahead of Phase 3 ECOSPOR III Study Read-Out

May 18, 2020 11:00 UTC

Data from SER-109 Phase 3 study in recurrent C. difficile infection expected mid-2020

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Seres Therapeutics, Inc. (Nasdaq: MCRB) today announced that it will host a virtual webcast symposium focused on SER-109 as a potential new therapeutic option for recurrent Clostridioides difficile infection (CDI) on Wednesday, May 27, 2020 from 8:30 to 9:30 a.m. ET.

During the event, Mark Wilcox, M.D., Professor of Medical Microbiology, University of Leeds, and Seres’ management will discuss the CDI patient burden, the ongoing SER-109 Phase 3 ECOSPOR III study and the potential for SER-109 to become the standard of care for recurrent CDI.

SER-109 is being evaluated in an ongoing Phase 3 study for the prevention of recurrence of CDI. SER-109 has obtained both Breakthrough Therapy Designation and Orphan Drug Designation from the U.S. Food and Drug Administration (FDA).

Seres previously reported the completion of enrollment in the Phase 3 ECOSPOR III study (ClinicalTrials.gov identifier: NCT03183128), a multicenter, randomized 1:1, placebo-controlled study in patients with multiply recurrent CDI. ECOSPOR III has enrolled 182 patients. Seres expects to report SER-109 Phase 3 top-line results in mid-2020.

Based on prior discussions with the FDA, Seres believes that ECOSPOR III has the potential to be the single pivotal study supporting product registration; however, this will depend on the strength of the data, and additional safety data may be required. If approved, SER-109 has the potential to be the first FDA-approved therapy for CDI to treat the underlying cause of this disease, and the first approved microbiome drug for any human condition.
