IntelGenx and RedHill Biopharma Announce Definitive Agreement for Commercialization of RIZAPORT(R) for Migraines with Pharmatronic Co. in South Korea

December 14, 2016

SAINT-LAURENT, CANADA -- (Marketwired) -- 12/14/16 -- IntelGenx Corp., (TSX VENTURE:IGX)(OTCQX:IGXT), and RedHill Biopharma Ltd. (NASDAQ:RDHL)(TASE:RDHL), 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. IntelGenx and RedHill 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. Further financial terms of the agreement were not disclosed. 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.

"We are most pleased to be entering 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 with 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."

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."

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.

IntelGenx and RedHill 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 2015(1). 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 population(2) and patients suffering from dysphagia (difficulty swallowing).
