IntelGenx Secures a License For Tadalafil Erectile Dysfunction Dosing Patent

SAINT LAURENT, QUEBEC--(Marketwired - Nov. 21, 2016) - IntelGenx Corp. (TSX VENTURE:IGX)(OTCQX:IGXT) (the "Company" or "IntelGenx") today announced the signing of a binding term sheet for a license to Eli Lilly and Company's tadalafil dosing patent, United States Patent No. 6,943,166 (the '166 dosing patent). Any exclusivity associated with the tadalafil compound patent is not affected by this agreement.

Subject to U.S. Food and Drug Administration (FDA) approval, this license allows IntelGenx to commercialize its Tadalafil ED VersaFilm™ product in the U.S. prior to the expiration of the '166 dosing patent. This license terminates all current tadalafil-related litigation activities for IntelGenx. IntelGenx will be actively seeking a partner for the commercialisation of the Tadalafil ED VersaFilm™ product.

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

IntelGenx plans to file Tadalafil VersaFilm™ 505(b)(2) NDA with the U.S. FDA in the second quarter of 2017 and expects a U.S. launch of the ED product upon approval, in the second quarter of 2018.

"Securing the license with Lilly is a significant achievement for IntelGenx. It will substantially alleviate any legal concern regarding the launch of our Tadalafil VersaFilm™ product ahead of the expiry of the '166 dosing patent," said Dr. Horst G. Zerbe, President and CEO of IntelGenx. "This license opens IntelGenx to the lucrative U.S. ED market and accelerates our partnering of this product for commercialising Tadalafil VersaFilm™ in the U.S. and abroad. We look forward to continuing IntelGenx' transformation into a global leader of pharmaceutical oral films."

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

About Tadalafil VersaFilm™

Tadalafil is one of the three major PDE5 inhibitors in the ED market. Tadalafil shows longer duration of action and less food effect compared with the competitors ED product. IntelGenx's tadalafil film offers an improved discrete dosage form that does not require water intake. IntelGenx tadalafil film formulations have been tested in various clinical trials to improve the pharmacokinetics and optimize the formulation. The latest formulation successfully demonstrated bioequivalence to Cialis^®(1) tablet in a pilot study. With the license in hand, IntelGenx may now target launch readiness ahead of Cialis^® patent expiry. Tadalafil VersaFilm™ now has the potential to be the first generic competitor to the Cialis^® tablet and the only film delivery product of the blockbuster ED drug product.
