Results of Pre-Clinical Investigations of Ceragenix's Developmental Antibiotic to Be Presented at International Scientific Meeting on Infectious Diseases

DENVER--(BUSINESS WIRE)--Sep 18, 2007 - Ceragenix Pharmaceuticals, Inc. (OTCB:CGXP), a biopharmaceutical company focused on infectious disease and dermatology, today announced that five poster presentations on the efficacy of its Ceragenin(TM) technology have been accepted for presentation at the upcoming annual meeting of the American Society for Microbiology's Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) to be held September 17th to 20th in Chicago, Illinois.

The five poster presentations accepted for presentation at ICAAC are:

(#274) Activity of the Novel Ceragenin CSA-13 vs. Carbapenem Resistant Non-Fermentative Gram-Negative Rods

(#275) In Vitro Activity of the Novel Ceragenin CSA-13 vs. Extended-Spectrum (beta)-Lactamase (ESBL) Producing Enterobacteriaeciae from the UK

(#276) Evaluation of the Novel Ceragenin, CSA-13 Activity and Potential Synergy (SYN) against Clinical Isolates of P. aeruginosa (PA), Including Multi-Drug Resistant PA (MDR-PA)

(#277) In Vitro Activity of the Novel Ceragenin CSA-13 vs. UK Pseudomonas aeruginosa Cystic Fibrosis Isolates

(#278) In Vitro Activity of the Novel Ceragenin CSA-13 vs. Multidrug-Resistant Strains of Acinetobacter baumannii

The research was conducted at Barts and The London National Health Service Trust, (London,UK), Queen Mary University (London, UK), Wayne State University (Detroit, MI), JMI Laboratory (North Liberty, IA) and Brigham Young University (Provo, UT).

In poster 277, Dr. Wareham and his colleagues in London assessed the activity of CSA-13 (one of the lead Ceragenin(TM) compounds) against a large collection of Pseudomonas aeruginosa bacterial strains obtained from Cystic Fibrosis (CF) patients including strains belonging to a highly transmissible virulent clone. The authors concluded that:

"The ceragenin CSA-13 shows promise as an alternative therapy for treatment of P. aeruginosa in CF patients. It was active against both multidrug resistant isolates and the transmissible virulent LES clone. Furthermore, like other cationic compounds (e.g., colisitin), CSA-13 may readily lend itself to administration by aerosolisation in order to deliver bactericidal concentrations of the agent into the lungs."

Steven Porter, Chairman and CEO of Ceragenix Pharmaceuticals stated: "We are very pleased that all five poster presentations submitted by investigators to ICAAC have been accepted for presentation at this international conference. We look forward to sharing the results of these studies with the scientific community at the annual ICAAC meeting."

About Ceragenins(TM)

Ceragenins(TM), or CSAs, are synthetically produced small molecule, positively charged, compounds comprised of a sterol backbone with amino acids and other chemical groups attached to them. These compounds are electrostatically attracted to the negatively charged cell membranes of certain viruses, fungi and bacteria. CSAs have a high binding affinity for such membranes (including Lipid A) and are able to rapidly disrupt the target membranes leading to rapid cell death. While CSAs have a mechanism of action that is also seen in antimicrobial peptides, which form part of the body's innate immune system, they avoid many of the difficulties associated with their use as medicines. Ceragenix is pursuing development of the Ceragenins for use as a topical antibiotic, as an antimicrobial coating for in-dwelling medical devices, and as a wound dressing. Ceragenix was recently awarded Frost & Sullivan's 2007 North American Technology Innovation Award for the field of Anti-Infective Coatings.
