Synthetic Biologics, Inc. is a clinical-stage biotechnology firm focused on creating treatments for illnesses with significant unmet medical demands. Among its leading product candidates is SYN-004, engineered to neutralize common intravenous beta-lactam antibiotics within the digestive system. This aims to safeguard the gut microbiome, prevent Clostridium difficile infections (CDI), curb the proliferation of harmful bacteria, combat antimicrobial resistance (AMR), and mitigate acute graft-versus-host-disease (aGVHD) in patients undergoing allogeneic hematopoietic cell transplants. Another key asset is SYN-020, an orally administered recombinant formulation of intestinal alkaline phosphatase, intended to address both localized gastrointestinal and systemic conditions. The company is also advancing VCN-01, a therapeutic candidate for various cancers, including pancreatic cancer, head and neck squamous cell carcinoma, colorectal cancer, and retinoblastoma. Additional clinical-stage programs include SYN-006, targeting the prevention of aGVHD and infections from carbapenem-resistant enterococci; SYN-007, designed to avert antibiotic-associated diarrhea linked to oral beta-lactam antibiotics; SYN-005, for the prevention and treatment of whooping cough (pertussis); and VCN-11, another cancer therapeutic. Synthetic Biologics maintains partnerships with Intrexon Corporation, The University of Texas at Austin, and Cedars-Sinai Medical Center. Furthermore, a clinical trial agreement with Washington University School of Medicine in St. Louis supports a Phase 1b/2a clinical trial for SYN-004. The company's main operations are based in Rockville, Maryland.
