PHILADELPHIA, Aug. 19, 2015 (GLOBE NEWSWIRE) -- As previously announced and provided in the proxy materials, the Management and the Board of Directors of Hemispherx Biopharma (NYSE MKT:HEB) will host a Stockholder Open House at its Manufacturing and Development Center in New Brunswick, New Jersey on August 25, 2015 at 10:00 a.m.

This gives stockholders a chance to see the upgraded facility. The construction phase at the facility was recently completed with more than $8 million in equipment upgrades, such as the new bioreactor systems. We anticipate that these Alferon upgrades will accommodate both a much higher volume production capacity and a far more cost effective manufacturing process for the production of Alferon N Injection®, the only FDA-approved natural alpha interferon. These improvements are critical for marketing a cost effective Alferon. The added efficiency integrates bioreactor with continuous flow manufacturing technology throughout the entire process. Hemispherx believes that this "state of the art" technology will lead to lower expense, enhanced yields, real-time monitoring, flexibility for tailored batch sizes, and improved operational safety.

The facility also houses the Company's Ampligen® manufacturing facility and we will tour that as well.

The open house will begin with a brief welcome and presentation by Mr. Equels. Afterwards, the Company's top manufacturing executives will lead small groups on a guided tour. The facility's processes are confidential and proprietary. Due to security issues all attendees at the Stockholder Open House must RSVP in advance and provide basic personal information to obtain security clearance. Please contact Charles Jones at (305) 987-7418 or  No photography will be allowed to protect the company's novel proprietary manufacturing processes and advanced applied technologies.

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

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.

The final results of these efforts could vary materially from Hemispherx's expectations. Finally, the projection of savings above is subject to change based upon operational requirements of the company and the possibility that additional finance and accounting staff may be required to accomplish the Company's goals and objectives.
