IntelGenx Announces Settlement of Suboxone® Patent Litigation

May 14, 2018

SAINT LAURENT, Quebec, May 14, 2018 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX-V:IGX) (OTCQX:IGXT) (the “Company” or “IntelGenx”) today announced that all patent litigation between the Company, Par Pharmaceutical, Inc., Indivior, Inc., Indivior UK Limited, and Aquestive Therapeutics, Inc. (formerly MonoSol Rx, LLC) related to Suboxone® film has been settled.

The settlement agreement permits Par to begin selling a generic version of Suboxone® film on January 1, 2023, or earlier under certain circumstances. Par is IntelGenx’s commercial and development partner for a generic version of Suboxone® sublingual film product, which is indicated for the treatment of opioid dependence.

“We are very pleased with this outcome,” commented Dr. Horst G. Zerbe, President and CEO of IntelGenx. “According to IMS data, the oral film market for opioid dependence in the United States was worth more than $1.8 billion in 2017.  That is undoubtedly larger today as the opioid abuse epidemic has continued to grow.”

About Opioid Addiction

Opioid addiction is one of the fastest growing public health epidemics in North America. In the U.S. alone, 2.5 million people struggle with opioid addiction and, according to the U.S. Centers for Disease Control, 78 people die each day from the disease. The Drug Addiction Treatment Act of 2000 allowed medical office-based treatment of opioid dependence and greatly expanded patient access to medication-assisted treatments. In 2015, the U.S. Health and Human Services Department announced it would move to expand access to medication-assisted-treatment even further by revising regulations that cap the number of patients who can be treated with buprenorphine products by physicians.

About Suboxone®

The U.S. Food and Drug Administration approved Suboxone® film in October of 2002 for use in the treatment of opioid dependence.  Suboxone® is a registered trademark of Indivior UK Limited and Suboxone® film is manufactured by Aquestive Therapeutics, Inc. Suboxone® film is composed of the two active ingredients: buprenorphine hydrochloride and naloxone hydrochloride.
