Hemispherx Biopharma to Present Data on the Activity of Ampligen® Against Cancer at CHI’s 4th Annual Immuno-Oncology Summit, August 29 through September 2, 2016 in Boston, MA

PHILADELPHIA, Aug. 29, 2016 -- Hemispherx Biopharma, Inc. (NYSE MKT:HEB) (the “Company” or “Hemispherx”), announced that it will present at CHI’s 4th Annual Immuno-Oncology Summit, August 29 through September 2, 2016 in Boston, MA.  Dr. Christopher Nicodemus of Hemispherx’ Scientific Advisory Board will present the presentation entitled “RINTATOLIMOD: Enhancement of immune responses with a well-tolerated selective TLR3 agonist. The potential for I-O combination.”

Dr. David Strayer, Hemispherx’ Chief Scientific Officer, stated, “The next major advance in immuno-oncology will be the use of combinations of drugs that favor the immune system to respond to checkpoint inhibition and improve upon the unprecedented results being recorded with this class of therapy.  We believe that Ampligen as a selective stimulator of innate and adaptive immune responses and modulator of the tumor micro-environment may play an important part in this emerging chapter in immuno-oncology.”

About Hemispherx Biopharma
Hemispherx 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 rintatolimod (tradenames Ampligen^® or Rintamod^®) and Alferon^® LDO. Rintatolimod 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 rintatolimod 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 pending 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.

Forward-Looking Statements
To the extent that statements in this press release are not strictly historical, all such statements are forward-looking, and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Words such as “intends,” “plans,” and similar expressions are intended to identify forward-looking statements. The inclusion of forward-looking statements should not be regarded as a representation by Hemispherx that any of its plans will be achieved. These forward-looking statements are neither promises nor guarantees of future performance, and are subject to a variety of risks and uncertainties, many of which are beyond Hemispherx’s control, which could cause actual results to differ materially from those contemplated in these forward-looking statements. Examples of such risks and uncertainties include those set forth in the Disclosure Notice, below, as well as the risks described in Hemispherx’s filings with the Securities and Exchange Commission, including the most recent reports on Forms 10-K, 10-Q and 8-K. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and Hemispherx undertakes no obligation to update or revise the information contained in this press release, whether as a result of new information, future events or circumstances or otherwise revise or update this release to reflect events or circumstances after the date hereof.

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 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. The clinical studies referenced herein have been previously reviewed by the FDA and are not, in and of themselves, a sufficient basis for approval in the United States. 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.

Information contained in this news release, other than historical information, should be considered forward-looking and is subject to various risk factors and uncertainties including, but not limited to, general industry conditions and competition; general economic factors; the Company’s ability to adequately fund its projects; the impact of pharmaceutical industry regulation and healthcare legislation in the United States and internationally; trends toward healthcare cost containment; technological advances, new products and patents attained by competitors; challenges inherent in new product development, including obtaining regulatory approval; the Company’s ability to accurately predict the future market conditions; manufacturing difficulties or delays; dependence on the effectiveness of the Company’s patents and other protections for products; and the exposure to litigation, including patent litigation, and/or regulatory actions; and numerous other factors discussed in this release and in the Company’s filings with the Securities and Exchange Commission. The final results of these efforts and/or any other activities could vary materially from Hemispherx’s expectations. Approval of Ampligen^® for CFS in the Argentine Republic does not in any way suggest that the Ampligen^® NDA in the United States will obtain commercial approval. Also, it is noted that ANMAT approval is only an initial, but important, step in the overall successful commercialization. Namely, additional steps required for commercialization in Argentina will require, among others, an appropriate reimbursement level, appropriate marketing strategies, completion of manufacturing preparations for launch including possible requirements for approval of final manufacturing, etc., and there are no assurances as to whether or when such multiple subsequent steps will be successfully performed to result in an overall successful commercialization and product launch.
