Results of Pre-Clinical Investigation of Ceragenix's Developmental Antibiotic to Prevent Sepsis Presented at International Scientific Meeting

DENVER--(BUSINESS WIRE)--Oct 22, 2007 - Ceragenix Pharmaceuticals, Inc. (OTCB:CGXP), a biopharmaceutical company focused on infectious disease and dermatology, today announced that researchers at the Johns Hopkins Burn Center presented data in a late-breaking poster presentation on use of systemically administered CSA-13 to prevent the development of sepsis in rats that had been exposed to endotoxin. The data was presented at the recent 40th annual meeting of the Society for Leukocyte Biology held in Boston, Massachusetts in a poster entitled "CSA-13 suppresses endotoxin shock induced by LPS in neonatal rats."

Sepsis is a leading cause of death among patients admitted to the hospital. There are over 750,000 cases of sepsis annually in the United States and over 200,000 deaths. Sepsis is of particular concern in patients with extensive burn injuries as they are at high risk of significant morbidity and death. The development of "sepsis" or "endotoxin shock" is related to the presence of lipopolysaccharides (LPS) on the cell wall of gram-negative bacteria (such as Pseudomonas aeuroginosa or E. Coli) or lipotechoic acid (LTA) on the cell wall of gram-positive bacteria (such as MRSA). The release of this toxin by the bacteria may lead to a cascade of inflammatory reactions resulting in organ failure and death. Prior published work had shown that CSA-13 (one of Ceragenix's lead compounds in the class of Ceragenin(TM) compounds) has very high binding affinity for LPS. In these series of experiments, the researchers evaluated whether injection of CSA-13 into rats might be able to reduce the mortality associated with endotoxin shock.

In these experiments 13-15 day old neonatal rats (Wistrar), were sensitized to LPS by injecting D + galactosamine (600 mg/kg). Control and treatment groups both received LPS (150 (mu)g/kg), whereas the treatment group received CSA-13 (6.5 mg/kg; i.p) 30 min prior to LPS. In the control group mortality was 100% at 24 hours contrasting with the treatment group in which 80% of the rats were still alive at 72 hours. Similar results were also obtained by pre-mixing LPS with CSA-13 (1:4 concentrations) prior to injection.

According to Carl Genberg, Senior Vice President of Research and Development of Ceragenix, "This significant improvement in mortality (p< 0.001) demonstrates that LPS neutralizing properties of CSA-13 may be effective in preventing endotoxin shock. Therefore, the combination of antibacterial action and LPS neutralization may render CSA-13 a novel drug candidate in prevention and treatment of septic shock."

Steven Porter, Chairman and CEO of Ceragenix stated, "Sepsis kills thousands of Americans annually and brings untold pain and suffering to affected patients and the family members. These preclinical results, especially when combined with our previous disclosures regarding the preclinical efficacy of CSA-13 against MRSA, VRSA and other resistant strains, are highly encouraging."

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.
