PolyMedix, Inc. (OTC BB: PYMX), an emerging biotechnology company focused on developing new therapeutic drugs to treat life-threatening infectious diseases and acute cardiovascular disorders, announced today that new pre-clinical data for its novel, defensin-mimetic antimicrobial compounds was recently presented at two prestigious scientific meetings, including the American Society of Microbiology. The data presented showed activity against oral mucositis and a broad array of pathogens, including malaria, candida, anthrax and foodborne pathogens. The presentations are available on PolyMedix’s website at www.Polymedix.com. “These data continue to support the breadth and potential of our defensin-mimetic antimicrobial compounds in addressing serious infectious diseases that cause severe human and public health issues,” commented Dr. Richard Scott, Vice President of Research at PolyMedix. “The importance of our research is reflected in the high degree of attention it receives from the scientific community. We remain committed to continuing research to further advance these programs and expanding their scope.” PolyMedix presented the following pre-clinical data in poster form at the Annual Society of Microbiology meeting in Louisiana on May 24 and 25:
- Small Nonpeptidic Mimics of Host Defense Proteins as Potential Antimalarial Drugs Under a grant received from the National Institute of Health (NIH), PolyMedix tested hundreds of its antimicrobial compounds and identified several new compounds that kill the malaria parasite, Plasmodium falciparum. These compounds show low cytotoxicity and do not harm human cells, as well as have the possibility for oral activity.
- Identification of Novel Host Defense Protein Mimics for Treatment of Oral Candidiasis Under a grant that PolyMedix received from National Institute of Health (NIH) to support the development of defensin-mimetic antimicrobial compounds for the treatment of oral candidiasis (a fungal infection), PolyMedix has identified several compounds that show cidal activity against Candida albicans. The compounds tested show varied selectivity profiles against human cells and bacteria, indicating that compounds can be identified that are active specifically against bacteria or fungi but do not harm human cells. In addition, the antimicrobial activity of the lead compounds was unaffected by saliva.
- Nonpeptidic Mimics of Host Defense Proteins as Antimicrobial Agents for Foodborne Pathogens PolyMedix continues to test its antimicrobial compounds against the most prevalent foodborne pathogens. The data presented showed that 30 of PolyMedix’s compounds are broadly active against at least 6 of the 8 foodborne pathogens tested. In addition, PolyMedix identified 14 highly selective compounds that have antimicrobial activity against Campylobacter jejuni, the leading cause of bacterial foodborne gastroenteritis. The results showed no evidence for the emergence of resistance in serial passage assays with Salmonella enterica versus the PolyMedix compounds.
About PolyMedix, Inc.PolyMedix is a publicly traded biotechnology company focused on the development of novel drugs for the treatment of serious infectious diseases and acute cardiovascular disorders. PolyMedix uses a rational drug design approach to create non-peptide, small-molecule drug candidates. PolyMedix’s lead antibiotic compound, PMX-30063, is currently in a Phase 2 clinical trial for treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSI) caused by Staph, including MRSA. PMX-30063 is a small-molecule that mimics the mechanism of action of human host defense proteins, a mechanism that is distinct from currently approved antibiotic drugs and is intended to make bacterial resistance unlikely to develop. PolyMedix’s lead heptagonist compound, PMX-60056, is in a Phase 2 clinical trial in patients undergoing PCI procedures. PMX-60056 is designed to reverse the anticoagulant activity of both heparin and low molecular weight heparins (LMWH). PolyMedix believes that PMX-60056 could potentially be a safer and easier to use anticoagulant reversing agent, with broader activity, than the currently approved therapy for reversing heparin and LMWH. In addition to its small molecule therapeutics, PolyMedix has polymeric formulations with the same mechanism of action as PMX-30063, PolyCides ®. PolyCides are intended for use in antimicrobial biomaterials applications as additives to paints, plastics, and textiles to create self-sterilizing products and surfaces.
