NEW BRUNSWICK, N.J., Aug. 31, 2015 (GLOBE NEWSWIRE) — Hemispherx Biopharma (NYSE MKT:HEB) recently hosted a Stockholder Open House in their manufacturing and Research and Development (R&D) facility in New Brunswick, NJ, showcasing its progress on all fronts and the near completion of its Alferon® manufacturing program as well as developments in its Ampligen® R&D program. During the tour, stockholders were taken throughout the Alferon® and Ampligen® manufacturing suites and also visited our Research and Development labs, where there has been a significant amount of resources spent on developing a biomarker for Ampligen® to treat Chronic Fatigue Syndrome (CFS). It was emphasized that to achieve accelerated commercial success in the short term, additional funding will be required to go from completion of construction to final Food and Drug Administration (FDA) approval of the Alferon® facility. Consistent with that, all available corporate resources must be directed to achieving this approval. Accordingly, all executive bonus programs, including contract bonuses, have been deferred until these Alferon® manufacturing goals have been achieved and adequate funds are generated to meet our additional research needs for our experimental therapeutic Ampligen®.HEB

The Company’s facility and equipment upgrades should lead to an innovative and efficient process for producing Alferon N Injection®, currently the only available FDA-approved natural alpha interferon. The construction of a new bioreactor with continuous flow manufacturing technology throughout is done, subject to required preapproval steps. This entire modern process is expected to dramatically lower costs of production, produce enhanced yields, allow real-time monitoring, create flexibility for tailored batch sizes, and improve operational safety. Comparisons show production efficiencies with this ‘state of the art’ system, compared to the old manual method, can lead to a 100-fold increase in volume compared to the individual flasks that were used previously.  Alferon® was originally produced, at the time of FDA approval, in six-liter volume flasks, equivalent to twelve vials at a time, using a manual process that was extremely labor intensive.  Based upon more than ten successful test batches using the new system, we know the new 600 liter bioreactor can produce 1,200 vials at a time, creating a larger amount of product with heightened efficiency, production run reliability and safety.

Tom Equels, President of Hemispherx, stated; “Dr. Carter, our CEO, and I are major stockholders. We are active investors in the Company and by deferring all bonuses until success is achieved we are putting ‘Our money where our mouth is! We were pleased to present our significant progress over the past two years, to our stockholders at the open house. The progress toward completion of our upgraded manufacturing facility is a very significant milestone in our quest for commercial success, making what we believe will be a breakthrough in the efficient high volume production of natural multi-species human alpha interferon. Although synthetic/recombinant alpha interferon comprise a multibillion dollar market, there is a significant percentage of interferon patients who, due to the development of neutralizing antibodies to recombinant interferon, may no longer respond to synthetic/recombinant alpha interferon treatments. Alferon® N is comprised of multiple subspecies of natural alpha interferon. The incidence of antibodies induced against natural interferon is very low (less than 0.2%). An analysis of relapsed and refractory NAB positive patients who switched treatment to natural interferon, such as leukocyte derived Alferon N Injection® (alpha-n3) or Wellferon® (alpha-n1), showed that in 33/40 (82%) of those relapsed or refractory patients switching to natural interferons, the clinical response was restored (Strayer, et al. J Interferon and Cytokine Research (2012) 32(3):95-102).  Because of these scientific observations, we firmly believe a strong market exists in the United States for our FDA approved use (See Below) and internationally, where we have already been approved in Argentina for use in any interferon-treatable disease where a patient has become refractory to synthetic/recombinant interferon.   A widened indication for use of Alferon® N in patients who are no longer responsive to synthetic interferon, as in Argentina, has not been reviewed and/or approved by the FDA.

Further, in our Ampligen® program we are developing compelling data on the relationship between natural killer (NK) cells and severe CFS. We are also in the process of evaluating the relationship between responders to our experimental therapeutic, Ampligen®, and NK cell levels in severe CFS victims. We believe that this further evaluation of the potential use of NK as a biomarker for severe CFS victims is an important component in moving Ampligen®, an experimental therapeutic, along the path to approval in the United States and in other countries. Our recently announced relationships with Emerge and myTomorrows provides an early access platform for our experimental therapeutic Ampligen for CFS patients in Europe and Australia.”

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.

Disclosure Notice

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.
