PHILADELPHIA, Sept. 15, 2015 (GLOBE NEWSWIRE) -- Hemispherx Biopharma (NYSE MKT:HEB) announced today the publication in the current issue of the peer reviewed Journal of Clinical and Cellular Immunology (Strayer D, et al, J Clin Cell Immunol 2015;6:4 http://doi.org/10.4172/2155-9899.1000348) an article entitled "Low NK Cell Activity in Chronic Fatigue Syndrome (CFS) and Relationship to Symptom Severity" in which 17 studies were reviewed that evaluated NK cell cytotoxicity (NKCC) data and the relationship to different CFS case definitions and CFS disease severity.
NK cells are an important component of the human immune response acting as a surveillance mechanism against invading pathogens and tumor cells. The review includes evidence that there is an association between decreased NK cell activity and increased CFS symptomatology.
New data was also reported in this publication, of in vitro exposure of peripheral blood mononuclear cells (PBMCs) from 15 CFS patients (mean average age 47.5 years and median age 46.1 years, 67% are female). These data indicated than in vitro treatment with Ampligen®, an experimental biotherapeutic, produced a 178% increase in mean NK activity (NKCC) and a 100% increase in median NK activity (NKCC). Patients in the study meet both the 1988 and 1994 case definitions of CFS as advanced by the Centers for Disease Control (CDC).
Further clinical studies are now underway in the U.S. to evaluate the interrelationships between CFS disease severity, dysfunction of NK cells, and therapeutic response to Ampligen®, an experimental biotherapeutic.
About Hemispherx Biopharma
Hemispherx Biopharma, Inc. is a specialty pharmaceutical company headquartered in Philadelphia, Pennsylvania and engaged in the clinical development of new drug therapies based on natural immune system enhancing technologies for the treatment of viral and immune based 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 including cancers. 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 FDA approval of Alferon N Injection® is limited to the treatment of refractory or recurrent external genital warts in patients 18 years of age or older. The Company's Alferon N Injection® 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.
The information in this press release includes certain "forward-looking" statements including without limitation statements about additional steps which the FDA may require and Hemispherx may take in continuing to seek commercial approval of the Ampligen® NDA for the treatment of Chronic Fatigue Syndrome in the United States. The production of new Alferon® API inventory will not commence until the capital improvement and validation phases are complete. While the facility is approved by FDA under the Biological License Application ("BLA") for Alferon®, this status will need to be reaffirmed upon the completion of the facility's enhancements prior to commercial sale of newly produced inventory product. If and when we obtain a reaffirmation of FDA BLA status and have begun production of new Alferon® API, we will need FDA approval as to the quality and stability of the final product to allow commercial sales to resume. The final results of these and other ongoing activities could vary materially from Hemispherx's expectations and could adversely affect the chances for approval of the Ampligen® NDA in the United States and other countries. Any failure to satisfy the FDA regulatory requirements or the requirements of other countries could significantly delay, or preclude outright, approval of the Ampligen® NDA in the United States and other countries. The re-launch of Alferon® N as a commercial product cannot commence until all regulatory approvals have been obtained.
