For more information regarding this class action suit, please contact Ryan & Maniskas, LLP ( Richard A. Maniskas, Esquire ) toll-free at (877) 316-3218 or by email at or visit: complaint alleges that during the Class Period, defendants issued materially false and misleading statements regarding the Company's business practices and financial results. Specifically, the complaint alleges that defendants failed to disclose that 2% of patients who were administered Omontys experienced hypersensitivity reactions resulting in anaphylaxis, a serious and life-threatening allergic reaction, a third of which needed medical intervention – and that 0.02% of those administered the drug experienced fatal anaphylaxis reactions. As a result of these false statements, the Complaint alleges that Affymax stock traded at artificially inflated prices during the Class Period, reaching a high of $27.74 per share in intraday trading on October 17, 2012.

Then, on February 23, 2013, Affymax and Takeda announced that the FDA was requiring a total recall of the drug due to reports of anaphylaxis, with the FDA calling it a "serious and life-threatening" allergic reaction in the agency's statement. "Serious and fatal" hypersensitivity reactions had been reported in some patients within 30 minutes of receiving their first doses of the drug by intravenous injection, the FDA said in its statement. On this news, the price of Affymax stock declined by more than 85%, closing at $2.42 per share, down $14.10 per share from the prior night's close, on unusually high trading volume.

If you are a member of the class, you may, no later than April 29, 2013, request that the Court appoint you as lead plaintiff of the class.  A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation.  In order to be appointed lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class.  Under certain circumstances, one or more class members may together serve as "lead plaintiff."  Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff.  You may retain Ryan & Maniskas, LLP or other counsel of your choice, to serve as your counsel in this action.
