Mallinckrodt's SpecGx LLC Reports on Outcome of FDA Joint Advisory Committee on Abuse-Deterrent, Immediate-Release Reformulation of Roxicodone® (Oxycodone Hydrochloride)

-- Committees Vote to Approve Drug with Abuse-Deterrent Labeling --

ST. LOUIS, Nov. 14, 2018 /PRNewswire/ -- SpecGx LLC (SpecGx), a subsidiary of Mallinckrodt plc (NYSE: MNK) that operates its Specialty Generics business, today announced that, in a joint meeting, the U.S. Food and Drug Administration's (FDA's) Anesthetic and Analgesic Drug Products Advisory Committee and Drug Safety and Risk Management Advisory Committee voted 10 to 7 to approve the SpecGx investigative abuse-deterrent formulation of immediate-release, single-entity oxycodone tablets for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.

Additionally, the Committees voted 12 to 5 that the drug should be labeled as an abuse-deterrent product by the nasal route of abuse.

The Committees also voted 10 to 7 that the drug should not be labeled as an abuse-deterrent product by the intravenous route of abuse.

SpecGx is advancing this reformulation of Roxicodone® (oxycodone hydrochloride tablets USP) with properties designed to deter intravenous and intranasal abuse under the company's 505(b)2 new drug application MNK-812. The company has been a leader for a number of years in delivering important solutions, including development of this technology, to reduce opioid misuse, abuse and diversion.

"We appreciate the Committees' thoughtful review and discussion of the potential benefits our new abuse-deterrent formulation drug can bring in helping to mitigate opioid abuse and misuse," said Matt Harbaugh, Executive Vice President, Chief Financial Officer and President, Specialty Generics. "We are encouraged by the positive feedback, and will work closely with the FDA to address any questions the Agency may have."

The role of the Committees is to provide recommendations to the FDA, though the recommendations are not binding.

The company has for years been at the forefront of preventing prescription drug diversion and abuse, and has invested millions of dollars in a multi-pronged program to address opioid abuse. In addition to abuse-deterrent technology, those efforts include the purchase and donation of nearly two million drug disposal pouches, and working with policymakers, community leaders, law enforcement and industry partners to ensure the responsible use of pain medication and preventing unused medications from ending up in the wrong hands. These efforts will continue to be supported.
