IntelGenx Announces Notice of Grant of European Patent Covering  Rizaport® VersaFilm™


Posted on: 19 Jun 18

SAINT LAURENT, Quebec, June 19, 2018 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX-V:IGX) (OTCQX:IGXT) (the “Company” or “IntelGenx”) today announced that the European Patent Office (“EPO”) has issued a “Notice of Intention to Grant” for the Company’s European Patent Application Number 14832172.2 entitled, “Instantly Wettable Oral Film Dosage Form Without Surfactant or Polyalcohol."  This is the first key patent allowed in Europe for the Company’s VersaFilm™ technology.

Once the administrative process is complete, the patent that issues from this application will provide intellectual property protection for the formulation of the Company’s VersaFilm™ technology used in its Rizaport® product, an oral thin film formulation of rizatriptan benzoate for the treatment of acute migraines, in Europe through 2034.  IntelGenx received a similar formulation patent covering its Rizaport® VersaFilm™ technology from the United States Patent and Trademark Office in 2016 and has additional applications pending in other countries.

“This is a significant and exciting decision by the EPO, and we view this announcement as recognition of IntelGenx’ important contributions to pharmaceutical oral films,” said Dr. Horst G. Zerbe, President and CEO of IntelGenx.

About RIZAPORT® (RHB-103):

RIZAPORT® is a proprietary oral thin film formulation of rizatriptan benzoate, a 5-HT1 receptor agonist and the active drug in Merck & Co.'s Maxalt®. RIZAPORT® 5 mg and 10 mg were approved for marketing in Germany in October 2015 and in Luxembourg in April 2017 under the European Decentralized Procedure. A New Drug Application for RIZAPORT® was resubmitted to the U.S. FDA in October 2017.

Rizatriptan is considered to be one of the most effective oral triptans, a class of molecules that constricts blood vessels in the brain to relieve swelling and other migraine symptoms. RIZAPORT® is based on IntelGenx's proprietary VersaFilm™ technology. It dissolves rapidly and releases its active ingredient in the mouth, leading to efficient absorption of the drug through the gastrointestinal tract. The administration method of the RIZAPORT® oral soluble film, which does not require the patient to swallow a pill or consume water, along with its neutral flavor, presents a potentially attractive therapeutic alternative for migraine patients, specifically for patients who suffer from migraine-related nausea, estimated to be approximately 80% of the total migraine patient population and patients suffering from dysphagia (difficulty swallowing)1.
