VenatoRx Pharmaceuticals to Present in vitro and in vivo Data for cefepime/VNRX-5133 at ECCMID 2018

VenatoRx Pharmaceuticals announced that fourteen poster presentations, including four oral sessions, will feature its lead clinical antibacterial candidate, cefepime/VNRX-5133, at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) at the IFEMA - Feria de Madrid in Madrid, Spain.

In addition, VenatoRx's President and CEO, Christopher J. Burns, Ph.D., will present a brief overview about the Company's R&D pipeline during Pipeline Corner on April 23, 2013 beginning at 12:30pm CET in Hall Y.

VNRX-5133 is a new-generation beta-lactamase inhibitor (BLI) with unique broad-spectrum activity, covering both serine- and metallo-beta-lactamases. VenatoRx is developing VNRX-5133 in a fixed combination with the 4^th generation cephalosporin, cefepime. VenatoRx believes that cefepime/VNRX-5133 has the potential to become a valuable treatment option for infections caused by multi-drug resistant (MDR) gram-negative bacteria, including carbapenem-resistant Enterobacteriaceae (CRE) and Pseudomonas aeruginosa, suspected polymicrobial infections caused by both gram-negative and gram-positive pathogens, and bioterror pathogens such as Burkholderia spp. and Salmonella spp.

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 Wellcome Trust under Award No. 360G-Wellcome-101999/Z/13/Z.
