NEW YORK, Nov. 20, 2009 (GLOBE NEWSWIRE) -- The Brualdi Law Firm, P.C. announces that a lawsuit has been commenced in the United States District Court for the Eastern District of Pennsylvania on behalf of purchasers of Hemispherx Biopharma, Inc. ("Hemispherx" or the "Company") (AMEX:HEB) stock during the period between February 18, 2009 and October 30, 2009, inclusive (the "Class Period") for violations of the federal securities laws.

No class has yet been certified in the above action. Until a class is certified, you are not represented by counsel unless you retain one. If you purchased Hemispherx common stock during the Class Period, and wish to move the court for appointment of lead plaintiff, you must do so by January 11, 2010. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in the Company during the Class Period. You do not need to seek appointment as a lead plaintiff in order to share in any recovery.

To be a member of the class you need not take any action at this time, and you may retain counsel of your choice. If you wish to discuss this action or have any questions concerning this Notice or your rights or interests with respect to these matters, please contact Sue Lee at The Brualdi Law Firm, P.C. 29 Broadway, Suite 2400, New York, New York 10006, by telephone toll free at (877) 495-1187 or (212) 952-0602, by email to or visit our website at

The Complaint alleges that, during the Class Period, defendants misled investors regarding the status of Hemispherx's New Drug Application ("NDA") for Ampligen with the U.S. Food and Drug Administration ("FDA"). Specifically, defendants failed to disclose and misrepresented the fact that the FDA had requested several reports from the Company before the NDA could even be considered, thus delaying the possible approval of Ampligen by several months at a minimum. On November 2, 2009, when the Company belatedly disclosed this information, the per share price of Hemispherx's common stock dropped from $1.45 on the previous day to $1.13, a drop of more than 20%. The next day, one commenter characterized the November 2nd Company "update" as essentially an admission "that its prior public statements were false and misleading."
