Venatorx Pharmaceuticals’ most advanced development-stage product is taniborbactam (formerly VNRX-5133), an injectable beta-lactamase inhibitor (BLI) that features selective and potent in vitro activity against both serine- and metallo-beta-lactamases (MBLs), including the following enzymes:
Venatorx believe that taniborbactam, 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 needs 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 bioterror pathogens such as Burkholderia spp.
Venatorx initiated enrollment in its Phase 3 trial of cefepime-taniborbactam in patients with complicated urinary tract infections (cUTIs) in August 2019, expects to enroll 582 patients for this study, with top-line results expected by the end of 2020.
This Phase 3 clinical trial (ClinicalTrials.gov – NCT03840148) is a global randomized, double-blind, active controlled, non-inferiority study evaluating the efficacy, safety, and tolerability of cefepime-taniborbactam in adults with cUTI, including acute pyelonephritis. The trial will assess the safety and efficacy of cefepime-taniborbactam as compared with that of meropenem using clinical cure and microbiological eradication as the primary composite efficacy endpoint.
