“We are delighted to enter into this first commercialization agreement for RIZAPORT^™ and look forward to building a long-term relationship with Grupo JUSTE in support of their efforts to introduce RIZAPORT^™ in Spain and potentially other LATAM and Middle Eastern territories,” said Adi Frish, RedHill’s Senior VP Business Development & Licensing. “We believe that, thanks to the pleasant flavoring and convenient use of the rapidly dissolving thin-film, RIZAPORT^™ could potentially become a preferred therapeutic option for migraine patients worldwide. We continue working diligently together with IntelGenx to bring this unique and advantageous drug to additional markets in the near future.”

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 agreement should allow Grupo JUSTE to bring this new effective treatment to migraine patients in Spain and potentially some Latin American and Middle East countries and to reinforce its presence in Neurology.”

The Federal Institute for Drugs and Medical Devices of Germany (BfArM) recently granted marketing authorization for RIZAPORT^™ 5 mg and 10 mg 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^™.

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. 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).
