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

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

SAINT LAURENT, Quebec, March 27, 2013 (GLOBE NEWSWIRE) -- IntelGenx Corp.
(TSX-V: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."
