Mallinckrodt Responds to Court Decision

Mallinckrodt plc (NYSE: MNK) said today that the U.S. District Court for the District of Maryland, Greenbelt Division, has denied its motion for a temporary restraining order (TRO) against U.S. Food and Drug Administration’s (FDA) November 13, 2014 reclassification of its generic methylphenidate hydrochloride extended release (ER) medicines.

“Mallinckrodt is disappointed by the court’s decision today, and we remain fully confident that our methylphenidate ER drugs are safe and effective when used in accordance with the approved labels,” said Peter Edwards, Mallinckrodt Senior Vice President and General Counsel. “We are evaluating all available options and look forward to engaging in meaningful dialogue with the FDA regarding this matter.”

Mallinckrodt has conducted a thorough examination of its pharmacovigilance database reports and found that in the 21 months since product launch, out of the more than 88 million doses of Mallinckrodt’s methylphenidate ER medicines that have been prescribed the company has received only 68 investigated and confirmed adverse event reports related to a lack of efficacy when the patient switched from the reference listed drug Concerta® to the company’s methylphenidate ER medicines.
