Hemispherx Biopharma, Inc. Announces Settlement of All Bioclones/Ribotech Litigation

Discussions in Progress for Potential Future Partnership in HIV/AIDS and Hepatitis


PHILADELPHIA, July 14, 2008 (PRIME NEWSWIRE) -- Hemispherx Biopharma, Inc. (AMEX:HEB) today announced that all outstanding legal issues between Hemispherx and Bioclones (Proprietary), Ltd. and Ribotech (Pty) Ltd have been resolved and that all litigation between the companies is in the process of being dismissed by mutual agreement. Additionally, based on current discussions, Hemispherx management sees the potential for a mutually beneficial new Ampligen(r) partnership with the principals now controlling Bioclones and Ribotech.

As part of the settlement announced today, Hemispherx has regained all marketing rights to Ampligen(r) which had been previously granted to Bioclones for Great Britain, the Republic of Ireland, Australia, New Zealand, Tasmania, Madagascar, Mauritius, Reunion, Indonesia, Papua New Guinea and all nations on the continents of Africa and South America.

In October 1994, Hemispherx entered into a licensing and marketing agreement with Bioclones, a South Africa-based biopharmaceutical company, with respect to co-development of various RNA drugs, including Hemispherx's lead investigational drug, Ampligen(r). Pursuant to the 1994 agreement a subsidiary, Ribotech (Pty) Ltd, was created for pharmaceutical manufacturing utilizing recombinant DNA technology. Subsequently, Hemispherx deemed the 1994 agreement void due to alleged failures of performance by Bioclones.

Subsequent actions in U.S. and foreign jurisdictions included a December 2004 multi-count complaint by Hemispherx naming Bioclones as part of a conspiratorial group seeking to illegally manipulate the Company's stock for purposes of bringing about a hostile takeover, as well as January, 2007 arbitration proceedings initiated by Bioclones in South Africa against Hemispherx to determine damages arising out of the termination of the marketing agreement between the two companies and an application in South Africa by Hemispherx for the dissolution of Ribotech. None of these actions resulted in judgments or the levying of damages against any of the parties. Under the settlement announced today, all damage claims have been waived by the parties.

In June, 2006, Sekunjalo, a major South Africa-based listed empowerment company, acquired the controlling interest in Bioclones. Hemispherx retains an approximate 9% equity position in Ribotech, which is engaged in pharmaceutical manufacturing utilizing recombinant DNA technology.

Ampligen(r)'s Commercial Status

In October, 2007, Hemispherx submitted a new drug application (NDA) with the United States Food & Drug Administration (FDA) for the potential use of Ampligen(r) to treat Chronic Fatigue Syndrome. The FDA formally deemed the NDA application complete for substantive review on July 7, 2008.

"We are pleased with these timely results which put to rest past disputes with Bioclones and Ribotech and to regain marketing rights to Ampligen(r) for the potential treatment of CFS in the regions where we had previously granted those rights to Bioclones. We believe that the parties currently controlling Bioclones and Ribotech constitute potentially worthwhile regional partners for us," commented William A. Carter, M.D., Chairman and CEO of Hemispherx. "In fact, we are encouraged that our current discussions may result in a partnership focusing on Ampligen(r) as a potential adjuvant in future HIV vaccine clinical trials, especially in Africa, where HIV/AIDS has taken millions of lives and threatens many millions more. Settling old disputes with this emerging regional biotechnology leader fits well into our strategy to intensify exploration of Ampligen(r)'s potential to enhance the effectiveness of future HIV vaccine candidates."
