NEW YORK, NY--(Marketwire - Feb 5, 2013) - Levi & Korsinsky announces that a class action lawsuit has been commenced in the United States District Court for the Southern District of California on behalf of investors who purchased Isis Pharmaceuticals, Inc.

The complaint alleges that throughout the Class Period Isis issued materially false and misleading statements regarding the safety and efficacy of its drug Kynamro, which was currently under development.

On October 16, 2012, the FDA issued a report noting that abnormal growths developed in 3.1% of patients treated with Kynamro, as compared to only 0.9% of patients who took a placebo, concluding that the development of these growths would need to be studied further. In addition, it was reported that three patients treated with Kynamro died during clinical testing. Upon this news, shares of ISIS declined $2.88 per share.

If you suffered a loss in ISIS you have until February 26, 2013 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn't require that you serve as a lead plaintiff.
