Ceragenix Compound Demonstrates Activity Against MRSA Biofilm

DENVER, COLORADO--(CCNMatthews - May 18, 2006) -

Over 100 Fold Greater Effect in Eradicating MRSA Biofilm than Vancomycin

Ceragenix Pharmaceuticals, Inc. (OTCBB:CGXP) today announced that in vitro testing performed by MBEC BioProducts (www.mbec.ca) has shown that its Ceragenin™ compound, CSA-13, was over 100 fold more effective in eradicating a methicillin resistant Staphylococcus aureus (MRSA) biofilm than vancomycin. Biofilms are slime-like colonies of bacteria that are responsible for many of the nearly one million medical device related infections each year and are believed to be responsible for approximately 65 percent of chronic infections.

The testing was performed by MBEC BioProducts, an independent testing laboratory located in Calgary, Canada, that has developed specialized methods and devices for testing the efficacy of compounds against biofilms. The device used in the testing allows the growth of biofilms from the same organism, such as Staphylococcus, in multiple wells for side-by-side comparisons of antimicrobial drugs in varying concentrations. Using the MBEC™ Assay, an MRSA biofilm was grown for 24 hours and then exposed to various concentrations of CSA-13 and Vancomycin. While Vancomycin is highly potent against free living or planktonic MRSA bacteria, it is unable to eradicate the MRSA bacteria in the form of biofilms. In contrast, CSA-13 was able to completely eradicate the MRSA biofilm at a very low concentration and showed a greater than 100 fold effect in this model relative to Vancomycin.

MRSA infections are of growing concern as approximately 70 percent of all staphylococcus infections in persons admitted to hospitals are now resistant to the methicillin class of antibiotics. MRSA infections may be spread by close physical contact with infected persons or by contact with towels, wrestling mats or even computer keyboards on which the bacteria are present. In the case of medical device infections, bacteria from the patient's own skin or from health care workers can colonize medical devices, causing life-threatening infections.

"We are very pleased with the results of this testing," stated Steven Porter, Ceragenix's Chairman and CEO. "Ceragenix continues to pursue the development of an antimicrobial coating that may be applied to medical devices to help reduce the morbidity and mortality caused by infections related to their use."

Ceragenix previously announced that it had entered into a Cooperative Research and Development Agreement with the US Centers for Disease Control and Prevention (CDC) to study the efficacy of its antimicrobial coating technology. That work is currently ongoing.

About Ceragenins™

Ceragenins™, or CSAs, are synthetically produced small molecule chemical compounds comprised of a sterol backbone with amino acids and other chemical groups attached to them. These compounds have a net positive charge that is 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 Pharmaceuticals, Inc. (OTCBB: CGXP - News) is a biopharmaceutical company that discovers, develops and commercializes novel anti-infective drugs based on its proprietary class of compounds, Ceragenins™ (or CSAs). Active against a broad range of gram positive and negative bacteria, these agents are being developed as anti-infective medical device coatings (Ceracides™) and as therapeutics for antibiotic-resistant organisms.

Ceragenix further owns exclusive rights to Barrier Repair Technology for the treatment of dermatological disorders including atopic dermatitis, neonatal skin disorders and others. Ceragenix's patented Barrier Repair Technology, invented by Dr. Peter Elias and licensed from the University of California, is the platform for the development of two prescription topical creams--EpiCeram® and NeoCeram®. Ceragenix recently received 510K marketing clearance from the U.S. Food and Drug Administration for its EpiCeram® Skin Barrier Emulsion to improve dry skin conditions and to relieve and manage the burning and itching associated with various dermatoses including atopic dermatitis, irritant contact dermatitis, radiation dermatitis, and other dry skin conditions by maintaining a moist wound and skin environment.
