Ceragenin Compound Demonstrates Potent Activity Against Multidrug Resistant Bacterial Strains of Pseudomonas

DENVER--(BUSINESS WIRE)--Dec 20, 2007 - Ceragenix Pharmaceuticals, Inc. (OTCBB:CGXP), a biopharmaceutical company focused on infectious disease and dermatology today announced that researchers at the Eugene Appelbaum College of Pharmacy at the Wayne State University, in collaboration with JMI Laboratories and Dr. Paul B. Savage of Brigham Young University, have demonstrated in a series of in vitro experiments that an investigational drug compound known as CSA-13 shows rapid killing activity and synergistic activity with conventional antibiotics against multidrug resistant Pseudomonas aeuroginosa bacterial strains. P. aeuroginosa is a leading cause of morbidity and mortality in patients with pneuomonia and other respiratory diseases. The research appears ahead of print in the December online publication of the Journal of Antimicrobial Chemotherapy, the official journal of the British Society for Antimicrobial Chemotherapy.

The research evaluated the minimum inhibitory concentrations (MICs) of CSA-13, against 50 isolates of P. aeruginosa including 17 meropenem resistant strains (MIC 50 of 256 mg/L). CSA-13 is a member of the family of Ceragenin(TM) compounds being developed by Ceragenix and is a synthetic non-peptide mimic of the naturally occurring antimicrobial peptide found in the lung. The researchers found that CSA-13:

-- Had a narrower range of MIC values (1-32 mg/L) than any of the other agents studied (cefepime, ciprofloxacin, piperacillin, tobramycin and meropenem)

-- Demonstrated synergistic activity with cefepime and ciprofloxacin leading to more rapid killing; and

-- Showed excellent activity against meropenem resistant strains with an MIC 50 of 8 mg/L (compared to MIC 50 of 256 mg/L of the 17 meropenem resistant strains

"This new compound has the potential to be a significant advance in the treatment of patients with pneumonia and other lung infections," says senior author Michael Rybak, a professor at the Anti-Infective Laboratory of the College of Pharmacy at the Wayne State University in Detroit, Michigan. Dr. Rybak is a member of Ceragenix's Scientific Advisory Board.

"The potent activity demonstrated by CSA-13 in this peer reviewed journal article lends support to our decision to use CSA-13 as the active ingredient in our Cerashield antimicrobial coating development program to help reduce the risk of ventilator associated pneumonia attributed to the use of endotracheal tubes," said Steven Porter, Chairman and CEO of Ceragenix Pharmaceuticals. "There are an estimated 250,000 cases each year of ventilator associated pneumonia and P.aeuroginosa is associated with a high rate of morbidity and mortality among such patients."
