March 28, 2017

SAINT LAURENT, QUEBEC -- (Marketwired) -- 03/28/17 -- IntelGenx Corp. (TSX VENTURE:IGX)(OTCQX:IGXT) (the "Company" or "IntelGenx") today announced that Eli Lilly and Company granted IntelGenx' VersaFilm™ an exclusive license for tadalafil film product under erectile dysfunction (ED) dosing patent, United States Patent No. 6,943,166 (the '166 dosing patent). Any exclusivity associated with the tadalafil compound patent expiring is not affected by this agreement.

"Obtaining exclusivity for our Tadalafil VersaFilm™ product is a significant achievement for IntelGenx," said Dr. Horst G. Zerbe, President and CEO of IntelGenx. "With this exclusive license, IntelGenx has the opportunity to be the first and only Tadalafil film product on the U.S. ED market while the '166 dosing patent remains in force. Exclusive access to Lilly's dosing patent will further accelerate our partnering activities while potentially securing our early entry into the lucrative U.S. ED market."

Subject to U.S. Food and Drug Administration (FDA) approval, this exclusive license allows IntelGenx to commercialize its Tadalafil ED VersaFilm™ product in the U.S. prior to the expiration of the '166 dosing patent. With this license, IntelGenx is the only company that has a free and clear pathway to launch a tadalafil film product for the treatment of ED in the U.S. The exclusivity provides an outstanding competitive advantage to IntelGenx' Tadalafil ED VersaFilm™ product and IntelGenx will continue its efforts to securing a strategic partnership for the commercialization of Tadalafil VersaFilm™.

IntelGenx has developed a proprietary process and formulation for manufacturing the Tadalafil ED VersaFilm™ product and plans to supply the product to multiple markets around the world.

IntelGenx was represented by H. Keeto Sabharwal and the law firm of Pillsbury Winthrop Shaw Pittman.
