MADISON, Wis. – Attorney General Josh Kaul, and the Wisconsin Department of Health Services (DHS), today announced that Wisconsin and 27 other states and territories sued Mallinckrodt ARD LLC, formerly known as Mallinckrodt ARD Inc. and previously Questcor Pharmaceuticals Inc. (collectively, Mallinckrodt), in the U.S. District Court for the District of Massachusetts. The complaint alleges that Mallinckrodt has violated the false claims acts by knowingly underpaying Medicaid rebates due as a result of large increases in the price of its drug H.P. Acthar Gel (Acthar).
“This case alleges significant financial harm to Wisconsin’s and other states’ Medicaid programs through the underpayment of required rebates,” said Attorney General Josh Kaul. “We must protect Wisconsin’s Medicaid program from any big drug company that attempts to profit by manipulating the system.”
