SAINT LAURENT, Quebec, May 21, 2014 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX-V:IGX) (OTCQX:IGXT) ("IntelGenx"), a Canadian drug delivery company focused on oral drug delivery, today reported, together with RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) ("RedHill"), an emerging Israeli biopharmaceutical company focused primarily on the development and acquisition of late clinical-stage proprietary drugs, positive results from a comparative bioavailability study with their anti-migraine VersaFilm™ product, an oral thin film formulation of rizatriptan for acute migraines. The study compared the anti-migraine VersaFilm™ product to the European reference drug Maxalt® lingua, marketed in Germany by MSD SHARP & DOHME GMBH, to support the planned submission of a European Marketing Authorization Application ("MAA") for the anti-migraine VersaFilm™ product during the third quarter of 2014.
The results of the study are subject to final quality assurance and an independent study report by the Canadian clinical research organization ("CRO") that conducted the study. The final independent report from the CRO is expected in the coming weeks.
The single-dose, crossover, comparative bioavailability study conducted in Canada followed a positive scientific advice meeting with the German Federal Institute for Drugs and Medical Devices (BfArM) previously announced by RedHill in November 2013. The study, which included 26 healthy volunteers, established the bioequivalence of the anti-migraine VersaFilm™ product and the European reference drug, Maxalt® lingua.
In light of the positive results from the bioavailability study and data from prior clinical studies conducted with the anti-migraine VersaFilm™ product, and subject to various regulatory requirements, IntelGenx and RedHill plan to submit a European MAA during the third quarter of 2014.
IntelGenx and RedHill previously conducted a successful bioavailability study which demonstrated the required U.S. Food and Drug Administration ("FDA") criteria for therapeutic bioequivalence between the anti-migraine VersaFilm™ soluble oral thin film product and the U.S. reference drug, Maxalt-MLT®. Following the successful bioequivalence study, IntelGenx and RedHill announced in 2013 the submission to the FDA and acceptance for review of a New Drug Application ("NDA") seeking marketing approval of the anti-migraine VersaFilm™ product. Following a Complete Response Letter received from the FDA in February 2014, which raised questions primarily related to Chemistry, Manufacturing and Controls ("CMC"), IntelGenx and RedHill recently reported that they believe that FDA approval of the anti-migraine VersaFilm™ product 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 the VersaFilm™ 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®. 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 20131.
The product is based on IntelGenx' proprietary "VersaFilm™" 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, estimated at approximately 80% of the total migraine patient population2.
