SAINT LAURENT, Quebec, Feb. 4, 2014 (GLOBE NEWSWIRE) -- IntelGenx Corp.
(TSXV:IGX) (OTCQX:IGXT) ("IntelGenx"), a Canadian drug delivery company
focusing on oral drug delivery, and RedHill Biopharma Ltd.
(Nasdaq:RDHL) (TASE:RDHL) ("RedHill"), an Israeli biopharmaceutical
company focused on the development and acquisition of late
clinical-stage drugs, today announced that they received a Complete
Response Letter ("CRL") from the U.S. Food and Drug Administration
("FDA") regarding the New Drug Application ("NDA") for their
VersaFilm(TM) Oral Film Product for the treatment of acute migraines.
The VersaFilm(TM) product is a proprietary oral thin film formulation
of rizatriptan benzoate, a 5-HT1 receptor agonist and the active drug
in Merck & Co.'s Maxalt(R).

A CRL is issued by the FDA's Center for Drug Evaluation and Research to
inform companies that certain questions and deficiencies remain that
preclude the approval of the application in its present form. The
questions raised by the FDA in the CRL regarding the NDA for the
anti-migraine VersaFilm(TM) product primarily relate to third party
Chemistry, Manufacturing and Controls ("CMC") and to the packaging and
labeling of the product. No questions or deficiencies were raised
relating to the product's safety and the FDA's CRL does not require
additional clinical studies.

While continuing to review the FDA's CRL, IntelGenx and RedHill believe
that they can supply the requested information based on available data.
IntelGenx and RedHill further believe that the majority of issues
raised by the FDA were recently addressed in an amendment submitted by
the companies to the FDA that has yet to be reviewed. The companies
will work with the FDA to address the remaining questions in the CRL
and plan to submit the requested information within a few weeks.

IntelGenx and RedHill have been in active discussions with potential
partners for the commercialization of the product and expect to advance
these discussions rapidly following FDA's CRL, which provides increased
regulatory clarity, indicates that no further clinical trials are
required, and raises no issues regarding to the product's safety.

"We appreciate the thorough review of the product NDA by the FDA. We
remain committed to bringing the product to market as quickly as
possible and will work closely with the FDA to advance the application
and address all questions raised by the FDA," said Rajiv Khosla,
IntelGenx' President and CEO and Dror Ben-Asher, RedHill's CEO in a
joint statement. "We believe that the questions raised by the FDA can
be addressed based on available data, and we plan to work vigorously to
submit our response within a few weeks in order to bring this product
to market as a new therapeutic option for the benefit of patients
suffering from migraines."

In addition to pursuing marketing approval in the U.S., and following a
positive meeting with the German pharmaceuticals regulation authority
"BfArM" in October 2013, IntelGenx and RedHill plan to complete the
development program for the European market and submit a Marketing
Authorization Application for marketing approval of the product in
Europe later this year, with Germany as the reference member state
under the European Mutual Recognition Procedure.

About the VersaFilm(TM) Oral Film Product:

The product is a proprietary oral thin film formulation of rizatriptan
benzoate, a 5-HT1 receptor agonist and the active drug in Merck & Co.'s
Maxalt(R). Rizatriptan is considered one of the most effective oral
triptans, a class of molecules that constrict blood vessels in the
brain to relieve swelling and other migraine symptoms. The worldwide
annual sales of triptans were estimated to have exceeded $1.6 billion
in 20121, and the worldwide direct sales of Merck & Co.'s
rizatriptan-based drugs exceeded $600 million in 20122.

The product is based on IntelGenx' proprietary "VersaFilm(TM)"
technology. It dissolves rapidly in the mouth, leading to the
absorption of the drug through the gastro intestinal track and into the
bloodstream. The administration method of the oral thin film does not
require the patient to swallow a pill or consume water, and presents a
potentially attractive therapeutic alternative for many migraine
patients, including those who suffer from migraine-related nausea -
approximately 80% of the total migraine patient population3.
