Indivior Enters into Settlement with Par Pharmaceutical in Patent Infringement Case

Slough, UK, May 14, 2018 – Indivior PLC (LON: INDV) (“Indivior” or the “Company”) today announced that its U.S. subsidiary, Indivior Inc., together with Aquestive Therapeutics, Inc. (formerly known as Monosol Rx, LLC), entered into a settlement agreement with Par Pharmaceutical Inc., Par Pharmaceutical Companies Inc., Endo International PLC (collectively, “Par”) and IntelGenx Technologies Corp., resolving patent litigation related to SUBOXONE® (buprenorphine and naloxone) Sublingual Film. The litigation has been pending in the U.S. District Court for the District of Delaware and resulted from Par’s submission of an Abbreviated New Drug Application (ANDA) to the U.S. Food & Drug Administration seeking approval to market generic versions of SUBOXONE® Film. The settlement permits Par to begin selling a generic version of SUBOXONE® Film on January 1, 2023, or earlier under certain circumstances. Other terms of the settlement are confidential.

As required by law, the parties will submit the settlement agreement to the U.S. Federal Trade Commission and the U.S. Department of Justice for review.

Shaun Thaxter, CEO of Indivior, said, “We are pleased to have amicably settled another piece of outstanding patent infringement litigation. We continue to seek greater certainty for Indivior, but on terms that adequately reflect the strength of our intellectual property, including the three new Orange Book patents that have been asserted against the remaining ANDA filers.”
