EDMONTON, Alberta — September 12, 2013. Fedora Pharmaceuticals, Inc. and its collaborators presented results of preclinical studies demonstrating that FPI-1465 increases the activity of β-lactam antibiotics against bacteria that have developed resistance through the production of β-lactamase enzymes.
In vitro, three β-lactam antibiotics (ceftazidime, aztreonam, and meropenem) were tested alone and in combination with FPI-1465. In each case the combination eliminated resistant bacteria at much lower concentrations. Against carbapenemase-producing bacteria, aztreonam showed up to 4,096-fold greater potency in combination with FPI-1465.
The synergy observed in these studies suggests that FPI-1465 has the potential to negate the mechanism of resistance employed by β-lactamase-producing bacteria and rescue the antimicrobial activity of the entire class of β-lactam antibiotics.Dr. Rodrigo E. Mendes, Associate Director, JMI Laboratories
Results were confirmed in vivo: in mice infected with resistant Klebsiella pneumoniae or Enterobacter cloacae, a single dose of FPI-1465 plus ceftazidime produced a roughly 3-log reduction in bacterial counts.
In these highly resistant strains, the degree of bacterial clearance generated by the combination of FPI-1465 plus ceftazidime is truly impressive.Christopher G. Micetich, Founder & CEO, Fedora Pharmaceuticals
