IntelGenx Announces Notice of Appeal for Buprenorphine/Naloxone Sublingual Film Product for the Treatment of Opiate Addiction

SAINT-LAURENT, QUEBEC--(Marketwired - July 11, 2016) - IntelGenx Corp. (TSX VENTURE:IGX)(OTCQX:IGXT), today announced the receipt of the recent notice of appeal for the buprenorphine/naloxone sublingual film product for the treatment of opiate addiction by Par Pharmaceutical, Inc. and IntelGenx Corp. to the United States Court of Appeals for the Federal Circuit from the final judgment issued by the U.S. District Court for the District of Delaware on June 28, 2016.

The ruling in the U.S. District Court of Delaware in the ANDA litigation of Par Pharmaceutical, Inc. and IntelGenx Technologies Corp. against Indivior PLC and Monosol Rx, LLC resulted in the following:

Par and IntelGenx prevailed on the non-infringement of the U.S. Patent No. 8,017,150, which is set to expire in 2023, and on the invalidity (all claims) and non-infringement (certain claims) of the U.S. Patent No. 8,475,832, which is set to expire in 2030.

The Court ruled that Par's ANDA product would infringe the asserted claims of U.S. Patent No. 8,603,514, one of the Orange Book listed patents for Suboxone Film, and that the asserted claims of U.S. Patent No. 8,603,514 were not shown to be invalid.

"We are working with Par in the appeal process and will provide an update to shareholders as items materialize," said Dr. Horst Zerbe, President and CEO of IntelGenx.

Dr. Zerbe further added, "We were very pleased to learn of the recent report that President Obama's administration will loosen its strict controls on buprenorphine, which is used to treat addiction to heroin and other opioid-based drugs. The Department of Health and Human Services up until now only allowed doctors to prescribe the medication to 100 patients at a time. Under the new rules, up to 275 patients at a time can be prescribed the drug."

About Suboxone®

The FDA approved Suboxone® in October of 2002 for use in the treatment of opioid addiction. Suboxone® is a registered trademark of and manufactured by Reckitt Benckiser Pharmaceuticals. Suboxone® is composed of the two active ingredients: buprenorphine and naloxone.

Naloxone is used to block the effect of opioids. Buprenorphine is a partial opioid agonist that stimulates opioid receptors but does not produce the same effects as an opioid. In other words it does not produce a euphoric "high" effect. The combination of these two actives has been shown to be efficacious in managing the treatment of opioid addiction. Suboxone® is most often taken sublingually (dissolved under the tongue). Taken properly it can reduce opioid use, help patients to be successfully managed in an addiction rehabilitation program, and depress the symptoms of opioid withdrawal. Suboxone® is the most commonly prescribed medication that is administered to patients during the maintenance phase of treatment. Unlike methadone, Suboxone® has a lower potential for overdose and abuse. This enables Certified Doctors, in certain circumstances, to prescribe take home supplies of Suboxone®.
