Background on the Questcor Securities Class Litigation The complaints charge Questcor and certain of its senior executives with violations of the Securities Exchange Act of 1934. Questcor is a California-based biopharmaceutical company specializing in the treatment of patients with autoimmune and inflammatory disorders. The Company’s primary product is H.P. Acthar Gel (“Acthar”), an injectable drug that is approved by the U. S. Food and Drug Administration (“FDA”) for the treatment of 19 conditions, including multiple scelorosis (“MS”), nephrotic syndrome and infantile spasms. The complaints allege that, throughout the Class Period, defendants issued false and misleading statements about Acthar’s effectiveness as a treatment for MS and nephrotic syndrome and the Company’s promotion of the drug. On September 19, 2012, Citron Research reported that Aetna Inc. (“Aetna”), one of the nation’s largest insurance companies, had revised its policy regarding Acthar, which would extensively limit coverage for the drug. Aetna had engaged in a review of the 19 indications for which the FDA had approved Acthar and determined that clinical research suggested the drug is only “medically necessary” for West syndrome, a rare condition that causes infantile spasms, and not for other indications, such as MS. On this news, the price of Questcor’s common stock fell $24.17 per share to close at $26.35 per share on September 19, 2012, a one-day decline of nearly 48%.
