About Venatorx Pharmaceuticals
Venatorx is a private pharmaceutical company that is focused on the discovery and development of novel anti-infectives to treat multi-drug-resistant bacterial infections and hard-to-treat viral infections. Founded in 2010, Venatorx has built a world-class in-house R&D organization that has filed over 100 patents spanning multiple research programs. Venatorx has received significant funding awards from the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH), Wellcome Trust, CARB-X, and the Defense Threat Reduction Agency (DTRA) as well as private equity investments from Versant Ventures, Abingworth, and Foresite Capital.

The Company’s most advanced development-stage product is VNRX-5133, an injectable beta-lactamase inhibitor (BLI) that features selective and potent in vitro activity against both serine- and metallo-beta-lactamases, including ESBL, OXA, KPC, NDM, and VIM enzymes. Venatorx believes that VNRX-5133, in a fixed combination with the fourth generation cephalosporin, cefepime, has the potential to provide a valuable broad-spectrum treatment option to meet unmet medical need in patients with infections due to carbapenem-resistant pathogens including carbapenem-resistant Enterobacteriaceae (CRE) and carbapenem-resistant Pseudomonas aeruginosa (CRPA), suspected polymicrobial infections caused by both gram-negative and gram-positive susceptible pathogens, and engineerable MDR bioterror pathogens such as Burkholderia spp. and Salmonella spp. Early clinical studies of cefepime/VNRX-5133 have been completed and Venatorx intends to initiate Phase 3 pivotal trials during the third quarter 2019. This project has been funded in whole or in part with Federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN272201300019C, and The Wellcome Trust under Award No. 360G-Wellcome-101999/Z/13/Z.

Venatorx’s second development-stage product in clinical development is VNRX-7145, an orally bioavailable BLI that in a fixed combination with the third generation orally bioavailable cephalosporin, ceftibuten, has the potential to rescue activity of the partner antibiotic against ESBLs and key carbapenem-resistant Enterobacteriaceae, including those expressing KPC and OXA carbapenemases. This project has been funded in part with Federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN272201600029C.

Additionally, Venatorx has a broad pipeline of preclinical programs including a novel class of Penicillin-Binding Protein (PBP) inhibitors that are impervious to beta-lactamase-driven resistance, and novel antiviral agents targeting Hepatitis B Virus.
