granted national marketing approval for RIZAPORTT for the treatment of

Letter received

-- RIZAPORTT, an oral thin film formulation of rizatriptan for acute
migraines, offers an innovative therapeutic alternative for many
migraine patients, primarily patients who suffer from dysphagia or
migraine-related nausea


IntelGenx Corp. (TSX VENTURE: IGX)(OTCQX: IGXT) and RedHill Biopharma Ltd. (NASDAQ: RDHL)(TASE: RDHL), today announced that the Federal Institute for Drugs and Medical Devices of Germany (BfArM) has granted marketing authorization of RIZAPORT™ 5mg and 10mg, an oral thin film formulation of rizatriptan benzoate for the treatment of acute migraines.

Over 50 million people in Europe are estimated to be affected by migraines. Approximately 2 million Europeans are prone to migraine attacks every day(1). The worldwide migraine market is expected to exceed $2 billion in sales in 2016.

The national approval of RIZAPORT™ in Germany was granted under the European Decentralized Procedure (DCP), in which Germany served as the Reference Member State. This authorization is the first national marketing approval of RIZAPORT™. Marketing authorization in Luxemburg, the Concerned Member State, is expected to follow. IntelGenx and RedHill intend to continue to work together to obtain national phase approvals in other European DCP territories.

"The European approval of RIZAPORT™ is an important milestone achieved by IntelGenx and RedHill which reflects our team's strong capabilities as partners," said Dr. Horst G. Zerbe, President and CEO of IntelGenx. "We are committed to bringing RIZAPORT™ to market as soon as possible as we believe it will be a beneficial treatment for patients suffering from migraines. This approval will make RIZAPORT™ the first oral thin film bioequivalent to Maxalt® Lingua."

Dr. Zerbe further added, "This approval in Europe for RIZAPORT™ further demonstrates my recent quote last week in our record third quarter results, that IntelGenx is clearly demonstrating that it is executing its strategy by advancing its strong product portfolio to become one of the leading drug delivery companies globally."

Dr. Reza Fathi, Ph.D., RedHill's Senior VP R&D, said: "We are very pleased to receive German marketing authorization for RIZAPORT™. This is the first drug in RedHill's advanced pipeline to gain marketing approval, a significant milestone for the Company that reflects our team's commitment and execution capabilities, as well as the successful cooperation with IntelGenx."

RIZAPORT™, an oral thin film formulation of rizatriptan for the treatment of acute migraines, offers a potentially attractive therapeutic alternative for many migraine patients. The RIZAPORT™ oral thin film has a pleasant taste and dissolves rapidly in the mouth, without the need for water. It is a therapeutic alternative for patients suffering from dysphagia (difficulty swallowing), and patients who suffer from migraine-related nausea, estimated to be approximately 80% of the total migraine patient population(2). 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.

IntelGenx and RedHill 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.

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®. 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 2014(3). 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.
