Theriva Biologics, Inc. is a clinical stage company, which engages in the development of therapeutics to preserve the microbiome to protect and restore the health of patients. The company is headquartered in Rockville, Maryland and currently employs 15 full-time employees. The firm is advancing a new oncolytic adenovirus platform. The Company’s candidates are VCN-01, SYN-004 (ribaxamase) and SYN-020. VCN-01, an oncolytic adenovirus designed to replicate selectively and aggressively within tumor cells, and to degrade the tumor stroma barrier that serves as a physical and immunosuppressive barrier to cancer treatment; SYN-004 (ribaxamase) which is designed to degrade certain commonly used IV beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, thereby limiting overgrowth of pathogenic organisms such as VRE (vancomycin resistant Enterococci), and SYN-020, a recombinant oral formulation of the enzyme intestinal alkaline phosphatase (IAP) produced under cGMP conditions and intended to treat both local GI and systemic diseases.
