February 22, 2013 Deadline -- HEB

NEW YORK, Feb. 1, 2013 (GLOBE NEWSWIRE) -- The Rosen Law Firm reminds
investors of the important February 22, 2013 lead plaintiff deadline in the
class action filed on behalf of investors who purchased the securities of
Hemispherx Biopharma, Inc., (NYSE:HEB) during the period from March 19, 2012
through December 17, 2012.

you may also email for information on the class action.

The Complaint asserts violations of the federal securities laws against
Hemispherx and its officers and directors for issuing false and misleading
information about its lead drug candidate Ampligen. Specifically, that
Hemispherx misstated the safety and efficacy of Ampligen, and touted
purportedly positive results from Ampligen's clinical trials.

On December 18, 2012, the FDA published a staff report concluding that the
Company's studies were "ill-defined and invalid" with signals of efficacy that
were inconsistent between clinical trials, and based on the limited quality of
the data, "it is difficult to draw conclusions regarding potential safety
signals," but the "review identified nine potential safety concerns associated
with Ampligen."The Complaint alleges that as a result of this adverse
information, Hemispherx stock price dropped and investors have been damaged.

If you wish to serve as lead plaintiff, you must move the Court no later than
February 22, 2013. A lead plaintiff is a representative party acting on
behalf of other class members in directing the litigation.If you wish to join

action, please contact Phillip Kim, Esq. of The Rosen Law Firm, toll-free, at
