Isis Pharmaceuticals, based in Carlsbad, California, is the leading company in gene-blocking antisense drug discovery and development. The Company's flagship product, Kynamro (formerly mipomersen), is designed to treat patients with severe forms of high cholesterol. The Complaint alleges that throughout the Class Period, Isis Pharmaceuticals issued false and misleading statements regarding the safety and efficacy of the drug, as well as reportedly positive results from Kynamro's phase three clinical trial, leading investors to believe that Kynamro would receive approval from the U.S. Food and Drug Administration ("FDA").

On October 16, 2012, an FDA advisory committee posted information on the FDA's website noting that in recent patient studies, 3.1 percent of patients, or 23 people treated with Kynamro developed tumors and three of them died, while only 0.9 percent, or two patients getting a placebo developed tumors. The Endocrinologic and Metabolic Drugs Advisory Committee also noted liver and blood vessel cancers were seen in earlier tests of the drug conducted on mice.

As a result of this disclosure, the price per share of Isis Pharmaceuticals common stock declined $2.88, or nearly 22%, to close that day at $10.27, on heavy trading volume.

If you are a member of the class, you may, no later than February 26, 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.
