Mallinckrodt Will Respond to U.S. House Committee on Oversight and Reform Request for Information on H.P. Acthar® Gel

January 14, 2019

Mallinckrodt confirmed  today that it is one of a dozen pharmaceutical manufacturers to receive a  request for information from Representative Elijah Cummings (D-Md.), Chairman  of the U.S. House of Representatives Committee on Oversight and Reform. The  company will cooperate with the inquiry.

The inquiry relates  to H.P. Acthar® Gel (repository corticotropin injection).

Since acquiring H.P. Acthar Gel in late 2014,  Mallinckrodt has invested more than $500 million in modernizing this important  therapy for appropriate patients.  In  accordance with Mallinckrodt's pledge on drug pricing and innovation any price  adjustments to the product have been limited to the mid-single digit percentage range, and  the company has taken no price action for Acthar in 2019. Mallinckrodt provides  discounts to this list price to payers, which the prior owner generally did not  offer.

Over the last several  years, Mallinckrodt proactively embarked upon a multi-year, multi-million  dollar endeavor to update and strengthen the foundational scientific rationale  of H.P. Acthar Gel based on modern clinical science and practice, product  presentation and manufacturing processes. These investments include seven  company-sponsored clinical trials targeting 1,100 patients and nearly three  dozen health economic outcomes research studies.
