Seres Therapeutics

Seres Therapeutics is a clinical-stage biotherapeutic company based in Cambridge, Massachusetts, that specializes in developing ecobiotic microbiome therapeutics aimed at restoring health by correcting dysbiosis in the microbiome. The company is advancing several product candidates, with its lead therapy, SER-109, currently in Phase III clinical trials to prevent recurrence of Clostridium difficile infection (CDI). Additional candidates in development include SER-287 for ulcerative colitis, SER-401 for use with checkpoint inhibitors in metastatic melanoma, and SER-301 for inflammatory bowel disease. The company is also working on SER-262 to address initial CDI recurrences and SER-155 to support patients after allogeneic hematopoietic stem cell transplants. Seres Therapeutics has established collaboration agreements with organizations such as Nestec Ltd. and Memorial Sloan Kettering Cancer Center, as well as partnerships with AstraZeneca. Founded in 2010, the company has evolved from its original name, Seres Health, Inc., reflecting its focus on microbiome-based therapeutic solutions.
