Its research programs were designed to use engineered probiotics, microbial-based therapeutics and other biologic approaches to treat or prevent disease. The company’s historical pipeline included SYN-010, an investigational therapy for constipation-predominant irritable bowel syndrome; SYN-004 (ribaxamase), an oral enzyme intended to reduce antibiotic-associated disruption of the gut microbiome; and SYN-020, an oral intestinal alkaline phosphatase program investigated for gastrointestinal and metabolic disorders. These candidates were experimental and subject to clinical and regulatory evaluation. In 2021, Synthetic Biologics changed its name to Theriva Biologics, Inc. and began trading under the symbol TOVX. Accordingly, information associated with the SYN symbol generally relates to the company’s former name and earlier development programs. The company’s work was primarily focused on advancing microbiome-based medicines rather than commercial products or services.AI Generated. May Contain Errors.
