Seres Therapeutics, Inc. Overview

Pro stress-test →

Seres Therapeutics is a late-clinical-stage biotechnology company working to revolutionize treatment of a wide range of diseases by modulating the function of the human microbiome. The company led the successful development and approval of VOWST™, the first FDA-approved orally administered microbiome biotherapeutic, which was sold to Nestlé Health Science in September 2024.

Strategic Profile

Pro stress-test →

Seres has implemented a corporate strategy to advance its live biotherapeutic programs in inflammatory and immune diseases, with a focus on inflammatory bowel disease and immune checkpoint-related enterocolitis. The company has reduced workforce by approximately 30% to extend cash runway through Q3 2026, pausing additional investment in the SER-155 Phase 2 transplant program while prioritizing early-stage inflammatory disease programs.

Competitive Landscape

Pro stress-test →

Seres competes in the live biotherapeutics and microbiome therapeutics space with competitors including Fate Therapeutics, Vir Biotechnology, and Altimmune. The company's differentiation comes from its Breakthrough Therapy-designated programs and successful VOWST proof-of-concept, though it faces challenges from larger biotechs with deeper pipelines and superior capitalization.
