The company’s research platform leverages enzyme and microbiome modulation technologies to counteract the unintended consequences of antibiotic therapies, aiming to reduce the incidence of Clostridioides difficile infection and other antibiotic‐associated complications. The company’s lead product candidate, ribaxamase (SYN-004), is an orally administered beta‐lactamase enzyme designed to degrade certain intravenous beta‐lactam antibiotics in the gastrointestinal tract, thereby protecting the gut from antibiotic‐induced dysbiosis. Ribaxamase has been evaluated in multiple clinical trials, including studies in patients undergoing treatment for serious infections such as pneumonia. Synthetic Biologics has also been advancing additional pipeline programs that explore microbiome‐based approaches for gastrointestinal and metabolic disorders. Synthetic Biologics collaborates with pharmaceutical partners to facilitate global development and commercialization, having secured agreements to support late‐stage studies and future market access. The company is led by President and Chief Executive Officer William H. Martin, under the guidance of an experienced board with deep expertise in biopharmaceutical research and development. Synthetic Biologics is committed to innovating solutions that address critical unmet needs in infectious disease and gastrointestinal health.AI Generated. May Contain Errors.
