IntelGenx Corp. Announces Licensing of Anti-Migraine Film Product From RedHill Biopharma Ltd.

SAINT LAURENT, QUEBEC--(Marketwire - April 21, 2010) - IntelGenx Corp. (TSX VENTURE: IGX) (OTCBB: IGXT) ("IntelGenx") today announced that it has executed a binding term-sheet with RedHill Biopharma Ltd., an Israeli corporation ("RedHill") to co-develop and license IntelGenx' first oral thin film product based upon the Company's proprietary VersaFilm technology. The product is intended for the rapid relief of migraine.

The term-sheet sets forth the main criteria to be incorporated into a definitive development and license agreement, subject to due diligence, under which RedHill would obtain exclusive worldwide rights to market and sell IntelGenx' rapidly dissolving anti-migraine oral film product. In exchange IntelGenx would receive upfront, milestone, and external development fees totalling up to $2.1 million from RedHill. RedHill will also be responsible for regulatory filing fees, if necessary. Furthermore, upon commercialization of the product, IntelGenx would receive 40% of all proceeds including, but not limited to, all sales milestones and income from the product world-wide. IntelGenx and RedHill have entered into a ninety day exclusivity period during which IntelGenx is prohibited from engaging in negotiations related to the product contemplated to be licensed to RedHill with any other party. The term-sheet also provides for a break-up fee in the event that IntelGenx or RedHill is unable to execute the licensing agreement under certain circumstances after the satisfactory completion of due diligence.

"We are excited to have concluded our first, of what we believe to be many future, thin film partnerships," said Dr. Horst G. Zerbe, President and Chief Executive Officer of IntelGenx. "This partnership will help accelerate the development of this product through to commercialisation and will allow us to focus on a large number of future compounds using our VersaFilm portfolio technology, the most notable of these future products being our erectile dysfunction film."

In the fourth quarter of 2009 IntelGenx announced the results of a clinical pilot study that suggests IntelGenx has successfully developed a product that is bioequivalent to a leading branded anti-migraine therapy. The product has been developed using IntelGenx' proprietary immediate release film VersaFilm drug delivery technology. VersaFilm provides a patent-protected method of formulating in a convenient and discrete dosage form.
