TEL-AVIV, Israel, Dec. 14, 2016 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (NASDAQ:RDHL) (TASE:RDHL) (“RedHill” or the “Company”), a biopharmaceutical company primarily focused on development and commercialization of late clinical-stage, proprietary, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, together with IntelGenx Corp. (TSX-V:IGX) (OTCQX:IGXT) (“IntelGenx”), a Canadian drug delivery company focused on oral drug delivery, today announced the signing of an exclusive license agreement with Pharmatronic Co. (“Pharmatronic Co.”) for the commercialization of RIZAPORT^® in the Republic of Korea (South Korea). RIZAPORT^® is a proprietary oral thin film formulation of rizatriptan for the treatment of acute migraines.

Under the terms of the agreement, RedHill granted Pharmatronic Co. the exclusive rights to register and commercialize RIZAPORT^® in South Korea. RedHill and IntelGenx are entitled to receive an upfront payment and will be eligible to receive additional milestone payments upon achievement of certain predefined regulatory and commercial targets, as well as tiered royalties. The initial term of the definitive agreement with Pharmatronic Co. is for ten years from the date of first commercial sale and shall automatically renew for an additional two-year term. Commercial launch in South Korea is estimated to take place in the first quarter of 2019.

Mr. Adi Frish, RedHill’s Senior VP Business Development & Licensing, said: “We are pleased to enter into our second commercialization agreement for RIZAPORT^® and look forward to building a long-term relationship with Pharmatronic Co. This agreement for South Korea follows our recent commercialization agreement with Grupo JUSTE S.A.Q.F for Spain. We continue working diligently together with our partner IntelGenx to bring this unique migraine drug to additional markets and expect to re-submit the RIZAPORT^® NDA to the FDA in the first half of 2017.”

“We are most pleased to enter the Asian market for the first time with Pharmatronic, a Korean organization committed to customer service excellence,” said Dr. Horst G. Zerbe, President and CEO of IntelGenx. “We will be working hard with our partners RedHill and Pharmatronic to bring our innovative product to market for patients in South Korea suffering from migraines. The execution of two commercialization agreements for RIZAPORT^® in less than six months demonstrates our relentless execution of strategy to bring our innovative products to the global market.”

RIZAPORT^® (5 mg and 10 mg) was granted marketing authorization by the Federal Institute for Drugs and Medical Devices of Germany (BfArM) under the European Decentralized Procedure (DCP), in which Germany served as the Reference Member State for other European Union (EU) countries. This authorization was the first national marketing approval for RIZAPORT^®. A first commercialization agreement was signed with Grupo JUSTE S.A.Q.F (Grupo JUSTE) for Spain and additional potential territories and, subsequently, a national Marketing Authorization Application (MAA) for RIZAPORT^® was submitted by Grupo JUSTE in Spain under the European DCP.

RedHill and IntelGenx expect to re-submit the RIZAPORT^® New Drug Application (NDA) to the FDA in the first half of 2017 and subsequently receive a new PDUFA (Prescription Drug User Fee Act) date and are currently in discussions with potential commercialization partners for the U.S. market.

About RIZAPORT^® (RHB-103):
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^®. RIZAPORT^® 5 mg and 10 mg were approved for marketing in Germany in October 2015 under the European Decentralized Procedure. A New Drug Application for RIZAPORT^® was also filed with the U.S. FDA in 2013 and a CRL was received in 2014. RedHill has entered into licensing agreements to commercialize RIZAPORT^® in Spain (with Grupo JUSTE S.A.Q.F) and in South Korea (with Pharmatronic Co.). Rizatriptan is considered to be one of the most effective oral triptans, a class of molecules that constricts blood vessels in the brain to relieve swelling and other migraine symptoms. The worldwide annual sales of triptans were estimated to have exceeded $690 million in 2015¹. RIZAPORT^® is based on IntelGenx's proprietary VersaFilm^™ technology. It dissolves rapidly and releases its active ingredient in the mouth, leading to efficient absorption of the drug through the gastrointestinal 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 flavor, presents a potentially attractive therapeutic alternative for migraine patients, specifically for patients who suffer from migraine-related nausea, estimated to be approximately 80% of the total migraine patient population² and patients suffering from dysphagia (difficulty swallowing).
