Mallinckrodt Will Appeal District Court Ruling in Case Involving Ongoing Acthar Medicaid Drug Rebate Dispute with the Centers for Medicare and Medicaid Services (CMS)

STAINES-UPON-THAMES, United Kingdom, June 1, 2020 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a global biopharmaceutical company, announced today that it will appeal a ruling by the U.S. District Court for the District of Columbia in a lawsuit filed by its subsidiary, Mallinckrodt ARD LLC, against the U.S. Department of Health and Human Services (HHS) and the Centers for Medicare and Medicaid Services (CMS), regarding the Medicaid drug rebate calculation for Acthar^® Gel (repository corticotropin injection).

The District Court denied the Company's request to reconsider its previous decision that declined to declare unlawful an action by CMS to effectuate a change in the base date average manufacturer price used to calculate those rebates. The Court also denied the company's request that it temporarily block CMS' action pending an appeal.  The Company will immediately appeal to the U.S. Court of Appeals for the D.C. Circuit, where it will seek to overturn the lower court decision and temporarily block CMS action during the appellate process. 

"We are disappointed by the Court's unwillingness to reconsider its previous decision. We believe the Court has misinterpreted the statute that governs the Medicaid drug rebate program and failed to hold the government accountable to a bedrock principle of administrative law that the government must give fair notice and a clear, legal basis for a change in policy, particularly when that policy has been relied upon by a regulated entity such as Mallinckrodt," said Mark Casey, Executive Vice President and Chief Legal Officer of Mallinckrodt. "We plan to immediately appeal to the U.S. Court of Appeals for the D.C. Circuit. Mallinckrodt remains committed to ensuring Medicaid patients have access to Acthar Gel therapy for the long term." 

In asking the Court to temporarily block CMS' action, the Company described the risk that allowing CMS to move forward could inhibit the Company's ability to fund research and development activities, including COVID-19 related activities, and effectuate its opioid settlement, among other issues.

As previously announced, in the absence of court intervention, the company would pay roughly $640 million in retroactive non-recurring charges from January 1, 2013 to March 27, 2020, and the annualized prospective change to the Medicaid rebate calculation would reduce Acthar Gel net sales by roughly $90 million to $100 million. Under a previous agreement with the government, CMS has agreed to not enforce a change in the Medicaid drug rebate calculation for Acthar Gel until at least June 14, 2020.
