IntelGenx submits New Drug Application for Anti-Migraine VersaFilm(TM)

Saint Laurent, Quebec--(Newsfile Corp. - March 27, 2013) - IntelGenx Corp. (TSXV: IGX) (OTCQX: IGXT) (“IntelGenx” or the “Company”), a Canadian drug delivery company focusing on oral drug delivery, today announced that, together with its co-development partner RedHill Biopharma (“RedHill”), it has submitted a 505(b)(2) New Drug Application (“NDA”) to the U.S. Food and Drug Administration (“FDA”) for the Company’s anti-migraine oral film product, a novel oral thin-film formulation based on its proprietary VersaFilm™ technology containing Rizatriptan, the active drug in Merck’s Maxalt-MLT® orally disintegrating tablets.

The company had previously announced a successful a pre-NDA meeting with the FDA following the successful completion of a bioequivalency study demonstrating that its oral film product is bioequivalent with Maxalt MLT®, a leading branded anti-migraine product manufactured by Merck & Co. According to Merck's most recent annual report, sales of Maxalt® were $638 million in 2012. The thin-film formulation of Rizatriptan has been developed in accordance with the co-development and commercialisation agreement with RedHill Biopharma Ltd. (NASDAQ: RDHL; TASE: RDHL) using IntelGenx' proprietary immediate release "VersaFilm™" drug delivery technology.

IntelGenx’ orally disintegrating film consists of a thin (30 – 50 µm) polymeric film which disintegrates rapidly upon oral administration, thereby releasing the active drug Rizatriptan and making it available for rapid absorption. The film does not require water for administration.

On announcing the news, IntelGenx' President and CEO Dr. Horst Zerbe commented “We are very excited with this filing as we believe that our Rizatriptan film is the first oral film product for the treatment of migraine for which a 505(b)(2) NDA has been submitted to FDA. We believe that the product has significant market potential as it is therapeutically equivalent to Maxalt-MLT® orally disintegrating tablets, is easy to use, and offers significant cost advantages over orally disintegrating tablets due to the fact that manufacturing costs of orally disintegrating tablets are generally higher than those of orally disintegrating films as they often require lyophilization of the drug and a complicated, and therefore very expensive, packaging system.”
