Robbins Umeda LLP is investigating whether officers and directors of Peregrine breached their fiduciary duties to shareholders by permitting and failing to correct insufficient controls and improper procedures that led to major discrepancies in the results of the company's mid-stage lung cancer trial. On September 24, 2012, Peregrine issued a press release warning that "investors should not rely on clinical data that the company disclosed on or before September 7, 2012 from its Phase II bavituximab trial in patients with second-line non-small cell lung cancer or any presentations or other documents related to this Phase II trial." After initially disclosing results on September 7, 2012, from the trial that claimed that lung cancer patients taking bavituximab had a doubled survival time, shares of Peregrine saw a 46% increase to $4.50. After the announcement of the discrepancies in the trial, shares of Peregrine fell from a closing price of $5.39 on September 21, 2012 to a closing price of $1.16 on September 24, 2012, a $440 million decline in market value.
