ACTIVE MOIETY
Originator: Novacta Biosystems; Developer: Novacta; Class: Antibacterial, Bacteriocin, Peptide Mechanism of Action: Cell wall inhibitor; Highest Development Phase: Phase I for Clostridium infections; Most Recent Events: 22 Jan 2016 NVB 302 is still in phase I development for Clostridium infections in United Kingdom, 24 Aug 2011 Phase-I clinical trials in Clostridium infections in United Kingdom (PO), 15 Sep 2009 Antimicrobial data from a preclinical trial in Bacterial infections presented at the 49th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC-2009)
ACTIVE MOIETY
Ceftriaxone instillation promoted C. difficile germination and high-level toxin production. Commencement of NVB302 and vancomycin instillation reduced C. difficile total viable counts rapidly with only C. difficile spores remaining within 3 and 4 days, respectively. Cytotoxin was reduced to undetectable levels 5 and 7 days after vancomycin and NVB302 instillation commenced in vessel 2 and 3, respectively, and remained undetectable for the remainder of the experiments. C. difficile spores were unaffected by the presence of vancomycin or NVB302. NVB302 treatment was associated with faster resolution of Bacteroides fragilis group.
