Mallinckrodt Pharmaceuticals to Unveil First Clinical Data on MNK-795, an Extended-Release Oxycodone

Mallinckrodt Pharmaceuticals to Unveil First Clinical Data on MNK-795, an Extended-Release Oxycodone and Acetaminophen Combination, at PAINWeek

Data describe a human abuse liability study, delivery profile and efficacy of MNK-795

ST. LOUIS--(BUSINESS WIRE)-- Mallinckrodt (NYS: MNK) announced today that the first clinical data on MNK-795 will be presented at PAINWeek 2013, to be held September 4-7 in Las Vegas. MNK-795 is an extended-release oral formulation of oxycodone and acetaminophen that has been studied in clinical trials for the management of moderate to severe acute pain where the use of an opioid analgesic is appropriate. On July 29, Mallinckrodt announced that the U.S. Food and Drug Administration (FDA) accepted for filing the New Drug Application for MNK-795 and granted priority review.


The data to be presented include results from a human abuse liability (HAL) study comparing certain abuse-related characteristics of intact and tampered-with MNK-795 with that of intact and tampered-with Percocet®1 (an immediate-release oxycodone/acetaminophen formulation); single- and multi-dose pharmacokinetic studies that characterize the drug release profile with immediate- and extended- release components over the 12-hour dosing interval; and a study of the compound's efficacy and safety in an acute pain model.

"We are pleased to share the first results from our MNK-795 clinical development program which, if approved, could be a critical milestone for us as an independent specialty pharmaceuticals company," said Mark Trudeau, President and Chief Executive Officer of Mallinckrodt. "Mallinckrodt's investment in MNK-795 exemplifies our longstanding commitment to provide medications for the treatment of patients with acute pain."

Currently, there are no extended-release oxycodone/acetaminophen combinations on the market for acute pain. In clinical trials, MNK-795 has been studied as two tablets dosed every 12 hours. The dosage form was designed using technology with both immediate- and extended-release components and potentially tamper-resistant properties.

In all, 15 abstracts for MNK-795 will be presented, including the following:
