The law firm of Lieff Cabraser Heimann & Bernstein, LLP reminds investors of the upcoming deadline to move for appointment as lead plaintiff in securities class litigation brought on behalf of investors who purchased or otherwise acquired the common stock of Insys Therapeutics, Inc. (“Insys” or the “Company”) (INSY) between March 3, 2015 and January 25, 2016, inclusive (the “Class Period”).

If you purchased or acquired Insys common stock during the Class Period, you may move the court for appointment as lead plaintiff by no later than April 4, 2016. A lead plaintiff is a representative party who acts on behalf of other class members in directing the litigation.

You may retain Lieff Cabraser, or other attorneys, as your counsel in the action.

The action alleges that during the Class Period, Insys and certain of its senior executives misrepresented and failed to disclose that Insys was engaged in off-label marketing of the Company’s core product, Subsys, that certain Insys employees were complicit in an illegal kickback scheme pursuant to which Insys paid millions of dollars to medical professionals in exchange for prescribing Subsys to patients, and, as a result of the foregoing, Insys’s financial results and guidance were materially false and misleading.

On April 24, 2015, the Southern Investigative Reporting Foundation (“SIRF”) reported an increasing number of patient deaths from off-label uses of Subsys. Following this article, the price of Insys stock fell $6.00 per share, to close at $56.42 per share on the next trading day, April 27, 2015.

On June 25, 2015, The New York Times reported that a nurse who was a top prescriber of Subsys pled guilty to federal charges of accepting kickbacks from Insys. On this news, Insys’s stock price fell $3.00 per share, to close at $35.74 on June 25, 2015.

On December 3, 2015, SIRF reported that Insys’s prior authorization unit routinely changed insurance codes for patients’ diagnoses to ones for “cancer” and engaged in other misconduct to deceive insurers. Following this news, Insys stock price fell $5.93 per share, to close at $26.06 on December 3, 2015.

On January 25, 2016, SIRF reported that Insys executives have continued to pressure the Company’s employees to develop new schemes to promote Subsys for off-label uses. On this news, Insys stock price fell $1.07 per share, to close at $21.58 on January 25, 2016.
