About the Lawsuit

The complaint alleges that, throughout the Class Period, Mallinckrodt and its CEO, Mark Trudeau, made a series of false and misleading statements and failed to disclose material adverse facts about the long-term sustainability of Mallinckrodt's revenues for HP Acthar Gel ("Acthar"), the only FDA-approved adrenocorticotropic hormone preparation. The action alleges that Acthar's monopoly status was the product of unlawful anticompetitive practices and failed to disclose that its increasing reliance on Medicare and Medicaid meant that Mallinckrodt's monopolistic Acthar revenue would be threatened if the government took action to limit the price paid for this drug by taxpayers.
