NDA for Rizatriptan Anti-Migraine VersaFilm(TM) to be Filed by the End of This
Month

SAINT LAURENT, Quebec, March 18, 2013 (GLOBE NEWSWIRE) -- IntelGenx Corp.
(TSX-V:IGX) (OTCQX:IGXT) (the "Company") today announced financial results for
its fiscal year ended December 31, 2012 and provided an update on operational
developments.

"We ended 2012 with cash exceeding $2 million, no debt, and our first
FDA-approved product, Forfivo XL, having been successfully launched in the USA
by Edgemont Pharmaceuticals," stated Dr. Horst G. Zerbe, President and CEO of
IntelGenx. "As we enter 2013, we have received payment of the $1.0 million
milestone invoiced to Edgemont at the end of the fourth quarter of 2012, and
we look forward to receiving royalty income from Forfivo XL whilst we pursue
licensing opportunities for the rest of the world. We will also continue to
focus our attention on achieving FDA approval of the remaining products in our
pipeline, with a 505(b)(2) NDA submission for our anti-migraine VersaFilm
product on track to be filed by the end of March 2013, as previously
disclosed."

Corporate Development Update

Anti-migraine VersaFilm™ (rizatriptan)

In May 2012, we announced the completion of the pivotal bioequivalence study
for a novel oral thin-film formulation of Rizatriptan, the active drug in
Maxalt-MLT® orally disintegrating tablets. The study results indicate that the
product is safe, and that the 90% confidence intervals of the three relevant
parameters Cmax, AUC(0-t) and AUC(0-infinity) are well within the acceptance
range for bioequivalency.

In November 2012 we announced the successful conclusion of a pre-New Drug
Application ("NDA") meeting with the U.S. Food and Drug Administration related
to our VersaFilm™ formulation of Rizatriptan. The purpose of the meeting was
to receive confirmation from FDA regarding the adequacy of the clinical,
non-clinical and CMC data for our proposed 505(b)(2) NDA submission, which we
are on track to file by the end of the first quarter of 2013.

Maxalt-MLT® is a leading branded anti-migraine product manufactured by Merck &
Co. Our thin-film formulation of Rizatriptan has been developed in accordance
with the co-development and commercialization agreement with RedHill Biopharma
Ltd. using IntelGenx' proprietary immediate release "VersaFilm™" drug delivery
technology.

Erectile Dysfunction VersaFilm™ (tadalafil)

Subsequent to the end of the year, in February 2013 we successfully completed
a pilot bioequivalence study on our erectile dysfunction VersaFilm™ product.
In a previous study, we had already demonstrated that we are able to formulate
a bioequivalent product. In the recently completed study, we showed that we
were additionally able to develop a faster formulation with a significantly
shorter T[max ]which will address the need for a faster tadalafil product.

Development and Commercialization Agreement with Par Pharmaceutical, Inc.

In December 2011 we announced the execution of a co-development and
commercialization agreement with Par Pharmaceutical, Inc. ("Par") for a new
product utilizing one of our proprietary oral drug delivery platform
technologies. This program continues to make progress. For commercial reasons,
and in order to protect both Par's and IntelGenx' competitive advantage, the
agreement stipulates that all information pertaining to the product, together
with financial terms of the agreement, are to remain confidential.

Antihypertensive VersaTab™ product

We recently completed a pilot bioequivalence study for our antihypertensive
project, INT0001, a generic equivalent to a major cardiovascular product,
using our proprietary VersaTab™ delivery technology. We continue to make
progress with the project and, together with our strategic partner, Dava
Pharmaceuticals Inc., are working diligently towards the filing of an ANDA
with the FDA.

Financial Results:

The cash balance of $2.1 million as at December 31, 2012 compares with cash of
$3.5 million at December 31, 2011. Net funds used in operations totaled $1.6
million in 2012, compared with net funds used of $2.3 million in 2011, and
funds used in investing activities totaled $0.3 million and $0.2 million in
2012 and 2011 respectively. Funds generated from financing activities were
$0.4 million in 2012 compared with $4.8 million in 2011, including $3.2
million from private placements completed in June 2011.

Accounts receivable of $1.3 million as at December 31, 2012 (December 31, 2011
- $0.3 million) includes an amount of $1.0 million related to the launch of
Forfivo XL™ that was invoiced to Edgemont Pharmaceuticals in the fourth
quarter of 2012. Payment against the invoice was received in February 2013.

Revenue improved from $0.4 million in fiscal 2011 to $1.2 million in 2012,
primarily due to the milestone payment of $1.0 million invoiced to Edgemont
Pharmaceuticals for the launch of Forfivo XL™ in the fourth quarter of 2012.

Total expenses increased from $2.9 million in fiscal 2011 to $3.5 million in
2012. The increase is primarily attributable to additional R&D expenditure of
$0.3 million related to costs associated with the technical transfer of
activities in preparation of the manufacture of Forfivo XL™ and a Product Fee
for Forfivo XL™ payable to the FDA.

The net loss decreased from $2.5 million in fiscal 2011 to a loss of $2.3
million in 2012, and the loss per share decreased from $0.05 per share in 2011
to $0.04 per share in 2012.
