New York, New York

Tripp Levy PLLC, a leading national securities and shareholder rights law firm, announces that it is investigating potential federal securities law claims against Arrowhead Research Corp. (NASDAQ: ARWR) (“Arrowhead” or the Company”) on behalf of Arrowhead shareholders.

On October 8, 2014, Arrowhead released disappointing data from its experimental hepatitis B therapy ARC-520. On that same day, it was reported that Arrowhead, however, knew for months that ARC-520 dosed at 1 mg/kg and 2 mg/kg yielded 0.2-log and 0.3-log reductions in hepatitis B viral load. Yet, despite this knowledge, Arrowhead allegedly misled investors to believe that ARC-520 was more potent and achieved viral load reductions in the range of 0.7 log or higher.

On this news, shares of Arrowhead Research fell $5.48 per share, or over 43%, to close at $7.03 per share on October 8, 2014.
