Rosen Law Firm Reminds Hemispherx Biopharma, Inc. Investors of Important Class Action Deadline -- HEB

NEW YORK, Jan. 4, 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) from March 19, 2012 through December 17, 2012.

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.
