Rhea-AI Summary

Seres Therapeutics announced that the FDA has approved VOWST (fecal microbiota spores, live-brpk), the first orally administered microbiota-based therapeutic for preventing recurrent C. difficile infection (CDI) in adults post-antibacterial treatment. The approval follows the successful Phase 3 ECOSPOR III study, which indicated that 88% of treated patients were recurrence-free at eight weeks. VOWST is expected to be available in June 2023, with a milestone payment of $125 million to Seres from Nestlé Health Science linked to the FDA approval. The joint commercialization effort aims to address a significant unmet medical need as recurrent CDI is a leading cause of hospital-acquired infections. The product does not treat CDI but aims to prevent its recurrence.
