SAINT-LAURENT, CANADA -- (Marketwired) -- 03/29/16 -- IntelGenx Corp. (TSX VENTURE:IGX)(OTCQX:IGXT) and RedHill Biopharma Ltd. (NASDAQ:RDHL)(TASE:RDHL) today announced the binding term sheet agreement with Grupo Juste S.A.Q.F for the commercialization of RIZAPORT™, a unique oral thin film for the treatment of acute migraines in the country of Spain. The definitive agreement plans to be signed within 60 days of the execution of the binding term sheet. Financial terms of the agreement were not disclosed.

IntelGenx further announced that the previously announced new U.S. formulation patent covering RIZAPORT™ will be issued by the U.S. Patent and Trademark Office (USPTO) on April 5, 2016. The patent, 9,301,948 is valid until 2034.
Grupo Juste is a prominent private Spanish company with over 90 years of experience in the research, development and commercialization of proprietary pharmaceutical products, including migraine and other central nervous system (CNS) drugs, in Europe, Latin America and other territories.

According to the term sheet, Grupo Juste will have obtained exclusive rights to market and sell RIZAPORT™ in Spain. In exchange, IntelGenx and RedHill will receive upfront and milestone payments, together with a share of the profits of commercialization. Commercial launch in Spain is estimated to take place in the second half of 2017. The initial term of the definitive agreement shall be for ten years from the date of first commercial sale of the product and shall automatically renew for one additional two-year term. The binding term sheet will give Grupo Juste the territory of Spain, with the right of first refusal for Belize, Caribbean, Chile, Colombia, Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Middle East and Morocco.

"We are most pleased to take this step towards our first of many potential commercial agreements for RIZAPORT," said Dr. Horst G. Zerbe, President and CEO of IntelGenx. "We will be working very hard with our partners at RedHill and Grupo Juste to make sure we bring this much needed product to patients suffering from migraines. The execution of this term sheet is the beginning for IntelGenx as we look forward to aggressively begin concluding agreements in bringing our innovative oral film products such as RIZAPORT to the global market."

Dr. Zerbe further added, "With the issuance of the Rizatriptan patent by the USTPO, we achieved a very significant milestone as it will give protection to the product and the underlying technology which will further enable promoting RIZAPORT to a future partner for the U.S. market."

Inés Juste, President of Grupo JUSTE added: "We are extremely satisfied to announce the planned arrival of this new formulation of a leading treatment for migraine. Our partners, IntelGenx and RedHill possess a deep knowledge in the pharmaceutical industry including strong leadership in innovative formulations that improve the compliance and the administration pattern of gold standard drugs. This term sheet should allow Grupo JUSTE to bring this new comprehensive treatment to Spain and potentially some Latin American and Middle East countries and to reinforce its presence in Neurology."

Background on RIZAPORT™:

IntelGenx and its co-development partner, RedHill Biopharma Ltd. submitted a New Drug Application (NDA) to the FDA in 2013 seeking marketing approval of RIZAPORT in the U.S. In 2014, the companies received a Complete Response Letter (CRL) from the FDA which raised questions primarily related to CMC. It is noted that no deficiency was raised relating to the safety or bio-equivalence data of RIZAPORT™. 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. IntelGenx and RedHill continue their cooperative effort 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.


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 5mg and 10mg was 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. Rizatriptan is considered 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 $870 million in 20141. 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 many migraine patients, including those who suffer from migraine-related nausea, estimated to be approximately 80% of the total migraine patient population.
