Exhibit 99.1
IntelGenx and RedHill Biopharma Submit
European Marketing
Authorization Application for Migraine Drug
RIZAPORT®
Saint Laurent, Quebec, - (Newsfile Corp. - October 1, 2014) - IntelGenx Corp. (TSXV: IGX) (OTCQX: IGXT) (IntelGenx), a Canadian drug delivery company focused on oral drug delivery, today announced, together with RedHill Biopharma Ltd. (NASDAQ: RDHL; TASE: RDHL) (RedHill), an Israeli biopharmaceutical company focused on late clinical-stage drugs for inflammatory and gastrointestinal diseases, including gastrointestinal cancers, that they have submitted a Marketing Authorization Application (MAA) to the German Federal Institute for Drugs and Medical Devices (BfArM) seeking European marketing approval of their oral thin film formulation of rizatriptan for acute migraines, under the brand name RIZAPORT®. The brand name RIZAPORT® was also conditionally approved by the U.S. Food and Drug Administration (FDA) as part of the New Drug Application (NDA) review process in the U.S., subject to a Complete Response Letter (CRL) received from the FDA in February 2014 and currently under discussions with the FDA.
The MAA was submitted under the European Mutual Recognition Procedure (MRP) with Germany as the reference member state. The submission is supported by several studies, including a recently completed comparative bioavailability study which successfully established the bioequivalence between RIZAPORT® and the European reference drug, Maxalt® Lingua, and follows a positive scientific advice meeting with the BfArM. RIZAPORT® 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 estimated to be approximately 80% of the total migraine patient population1.
IntelGenx and RedHill previously conducted a successful bioavailability study which demonstrated the required FDA criteria for therapeutic bioequivalence between the RIZAPORT® soluble oral thin film and the U.S. reference drug, Maxalt-MLT®. Following the successful bioequivalence study, IntelGenx and RedHill announced in March 2013 the submission to the FDA and acceptance for review of an NDA seeking marketing approval of the product in the U.S., also under the brand name RIZAPORT®. Following a CRL received from the FDA in February 2014, which raised questions primarily related to Chemistry, Manufacturing and Controls (CMC), IntelGenx and RedHill reported that they believe that FDA approval of the RIZAPORT® NDA is subject to the satisfactory resolution of the remaining CMC questions, as well as securing a compliant source of the raw material. Accordingly, the companies continue to work with the FDA in order to address and resolve all remaining CMC questions and to secure a compliant source of the raw material.
"We are very pleased with the submission of a European marketing application for RIZAPORT®, which follows our submission of a U.S. New Drug Application currently under discussions with the FDA" said Dr. Elkan Gamzu PhD, RedHill's RIZAPORT® Product Manager. "This regulatory submission in Europe brings us closer to offering a new and potentially advantageous therapeutic alternative for patients suffering from migraines, including those who suffer from migraines with nausea and vomiting. We believe that RIZAPORT® oral thin film's rapid dissolution, pleasant flavoring and ease of use from the ability to administer without water, potentially improves compliance and adherence, and we look forward to making the product available to patients in Europe."

"From a commercial perspective, obtaining marketing authorization in Europe would expand the commercialization of RIZAPORT® into the second largest market of Maxalt®" said Dr. Horst G. Zerbe, President and CEO of IntelGenx. "Pursuing development activities in Europe demonstrates our commitment to bring RIZAPORT® to migraine patients across the world and maximize the value of this asset."
About RIZAPORT®:
RIZAPORT® is a proprietary oral thin film formulation of
rizatriptan benzoate, a 5-HT1 receptor agonist and the active drug in Merck
& Co.s Maxalt®. Marketing applications for
RIZAPORT® have been filed both in the U.S. (NDA filed in March
2013) and in Europe (MAA filed in October 2014). 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 billion in
20132.
RIZAPORT® is based on IntelGenx' proprietary VersaFilm technology. RIZAPORT® dissolves rapidly and releases its active ingredient in the mouth, leading to an efficient absorption of the drug through the gastro intestinal tract. The administration method of the RIZAPORT® 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 estimated to be approximately 80% of the total migraine patient population3.
