PHILADELPHIA, Aug. 26, 2013 (GLOBE NEWSWIRE) -- Hemispherx Biopharma (NYSE:HEB) announced that at the 2 nd International Conference on Biodefense and Natural Disasters meeting in Orlando, FL on August 22, 2013, Professor Dr. Juergen A. Richt, DVM, Ph.D., a scientific advisor to Hemispherx, described his experiments in human lung cells evidencing that Alferon N Injection®, the only multi-species, natural interferon approved in the U.S. for the treatment of human refractory HPV genital warts, is biologically active, in low doses, against various classes of viruses occurring naturally in animals and humans. Dr. Richt is the Director of the U.S. Department of Homeland Security Center of Excellence for Emerging and Zoonotic Animal Diseases, the Regents Distinguished Professor at Kansas State University, and an Eminent Scholar of Kansas Bioscience Association. The increasing prevalence of oseltamivir-resistant Influenza A viruses, particularly H7N9, has been widely reported and is due in large part to the fact that just a single-step mutation in the neuraminidase gene of this genetically unstable virus makes it resistant to oseltamivir (Tamiflu, Relenza). Dr. Richt reported on this instability in 2010 in the peer-reviewed Journal of General Virology, an international journal (" Viral reassortment and transmission after co-infection of pigs with classical H1N1 and triple-reassortant H3N2 swine influenza viruses", http://vir.sgmjournals.org/content/91/9/2314.short.) Hemispherx believes that the results of Dr. Richt's recent Kansas State University experiments, coupled with his work on reassortment and other published studies, set the stage for evaluating the possibility that mutational changes and reassortment could be prevented in animals by the use of type I interferon and/or a type I interferon inducer. Professor Richt's diverse experimental program, sponsored in part by the US Department of Homeland Security, National Institutes of Health, European Union, US Department of Agriculture, and private entities, focuses on molecular mechanisms and pathogenesis of emerging pathogens in livestock populations as a critical first step in promoting and causing human disease, including various zoonotic viruses such as highly pathogenic influenza viruses, H7N9 or H5N1(i.e., zoonotic agents).
New data regarding the genesis of pandemic flu, recently summarized by researchers at the National Institutes of Health in " Pandemic Influenza Viruses — Hoping for the Road Not Taken", David M. Morens, M.D., Jeffery K. Taubenberger, M.D., Ph.D., and Anthony S. Fauci, M.D. N Engl J Med 2013; 368:2345-2348 June 20, 2013DOI: 10.1056/NEJMp1307009, identifies viral reassortment events occurring in farm animals as potential major contributors to the eventual and inevitable jump into humans (cross-species transmission). Professor Richt is recognized as an expert on zoonotic agents (i.e., influenza, Prions, Rift Valley Fever, etc.) and has published extensively on the monitoring of the mutations and the basic events leading to cross-species transmission and the opportunities to adapt to its new human host with the potential to cause a pandemic.At the Orlando Conference, Dr. Richt described his ongoing research with Alferon®, including in-vitro experiments directed against inhibiting Tamiflu-resistant H7N9 influenza viruses. His laboratory results to date suggest that Alferon® may be a promising candidate to treat the virulent, and proved lethal Tamiflu-resistant H7N9 virus in animals and humans. Moreover, Hemispherx's previous research suggests that Alferon ® may be active against a range of viruses existing in animal populations even in the low dose oral (LDO) formulation referred to as Alferon® LDO. About Center of Excellence for Emerging and Zoonotic Animal Diseases, Kansas State University CEEZAD, Center of Excellence for Emerging and Zoonotic Animal Diseases, was officially inaugurated in June 2010, with its first annual conference held in Manhattan, Kansas, home of Kansas State University. CEEZAD was formed to enhance the capability of the US Department of Homeland Security by developing "state of the art" countermeasures for high priority emerging and zoonotic animal diseases. The College of Veterinary Medicine at Kansas State University was established in 1905. Since then, more than 5,000 men and women have been granted the Doctor of Veterinary Medicine degree. Departments within the College of Veterinary Medicine are anatomy and physiology, clinical sciences, diagnostic medicine/pathobiology.
About Hemispherx BiopharmaHemispherx Biopharma, Inc. is an advanced specialty pharmaceutical company engaged in the manufacture and clinical development of new drug entities for treatment of seriously debilitating disorders. Hemispherx's flagship products include Alferon N Injection® and the experimental therapeutics Ampligen® and Alferon® LDO. Ampligen® is an experimental RNA nucleic acid being developed for globally important debilitating diseases and disorders of the immune system, including Chronic Fatigue Syndrome. Hemispherx's platform technology includes components for potential treatment of various severely debilitating and life threatening diseases. Because both Ampligen® and Alferon® LDO are experimental in nature, they are not designated safe and effective by a regulatory authority for general use and are legally available only through clinical trials. Hemispherx has patents comprising its core intellectual property estate and a fully commercialized product (Alferon N Injection®), approved for sale in the U.S. and Argentina. The Company's Alferon N approval in Argentina includes the use of Alferon N Injection (under the brand name "Naturaferon") for use in any patients who fail or become intolerant to recombinant interferon, including patients with chronic active hepatitis C infection. The Company wholly owns and exclusively operates a GMP certified manufacturing facility in the United States for commercial products. For more information please visit www.hemispherx.net.
