SAINT LAURENT, Quebec, Dec. 1, 2014 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX-V: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 primarily focused on late clinical-stage drugs for inflammatory and gastrointestinal diseases, including gastrointestinal cancers, that the German Federal Institute for Drugs and Medical Devices ("BfArM") validated the Marketing Authorization Application ("MAA") for RIZAPORT™, an oral thin film formulation of rizatriptan for acute migraines, and has initiated the formal review process of the application on November 25, 2014. BfArM's potential feedback regarding the MAA is expected during the second half of 2015.

RIZAPORT™ oral thin film does not require the patient to swallow a pill or consume water and presents an 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.

The MAA was submitted under the European Mutual Recognition Procedure with Germany as the reference member state and Luxemburg as the Concerned Member State. The submission is supported by several studies and follows a positive scientific advice meeting with the BfArM.

IntelGenx and RedHill submitted a New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") in March 2013 seeking marketing approval of RIZAPORT™ in the U.S. Following a complete response letter received from the FDA in February 2014, which raised questions primarily related to 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.

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. It 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 which does not require the patient to swallow a pill or consume water, along with its pleasant flavoring, presents an 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.
