Hemispherx Biopharma Gains Regulatory Approval of Alferon Under the Brand Name "Naturaferon" in Argentina

PHILADELPHIA, Jan 26, 2012 (GlobeNewswire via COMTEX) -- Hemispherx Biopharma, Inc. HEB -19.15% (the "Company" or "Hemispherx") today announced that ANMAT (Administracion Nacional de Medicamentos, Alimentos y Tecnologia Medica), the agency responsible for the national regulation of drugs, foods and medical technology in Argentina, has approved the sale and distribution of Alferon N Injection(R) (under the brand name "Naturaferon") in Argentina. In June 2010, Hemispherx agreed to provide GP Pharm an option to market Alferon N Injection(R), its FDA-approved natural interferon, in Argentina and other Latin America countries. In December 2010, GP Pharm exercised this right and in July 2011 GP Pharm submitted an application for approval to ANMAT. Alferon N Injection(R) (Interferon alfa-n3 (human leukocyte derived)) is already approved in the US for the treatment of refractory or recurring external condylomata acuminate (genital warts) in patients 18 years of age or older. A major multi-million dollar investment scale-up of Alferon N Injection(R) manufacturing is underway at Hemispherx's New Brunswick, NJ facility.

According to a World Health Organization report on Human Papillomavirus (HPV), "Genital warts are very common and are highly infectious, and between 90% and 100% are caused by HPV genotypes 6 and 11. Although they do not usually result in death, genital warts cause significant morbidity and entail substantial health care costs. Recurrence is common."

Mr. Thomas Equels, Executive Vice Chairman of Hemispherx, stated "This approval is the result of Hemispherx's global business development initiatives which it plans to continue and to expand. It also reflects the increased capability of Hemispherx clinical and regulatory team to manage regulatory environments outside the US and to gear up to comply with import-export regulations in various countries. We are confident about the commercial opportunities for Alferon N Injection(R) in Argentina and pleased with the progress GP Pharm has made as is evidenced by this approval and parallel programs planned for Latin America."

Dr. Jorge Candal, Medical Director of GP Pharm, said, "We are pleased that ANMAT has understood the effectiveness of the unique technology platform represented by Alferon N Injection(R). We believe it can make a significant health impact in the lives of numerous patients in Argentina."

Jorge Braver, President of GP Pharm, said, "We are very excited about the approval of Alferon N in Argentina, and we look forward to providing it to patients in Argentina who will benefit from this unique, natural interferon."

Hemispherx continues to undertake its projected approximately $6.5 million expansion to its Good Manufacturing Process (GMP) manufacturing facility in New Brunswick, New Jersey including capital improvements, system upgrades and the introduction of building management systems to enhance production of our three products: Alferon N Injection(R), Alferon(R) LDO and Ampligen(R). One of the primary goals for these enhancements to our FDA licensed facility is to accommodate larger production volumes of Alferon N Injection(R) for anticipated global requirements.
