RedHill Biopharma Announces Positive Scientific Advice Meeting and European Marketing Application Strategy for RHB-103 (Migraine)

18 November, 2013
  • The Company and its co-development partner, IntelGenx Corp., held a Scientific Advice meeting with the German pharmaceuticals regulation authority (BfArM) and plan to submit a Marketing Authorization Application (MAA) to market RHB-103 in Europe during the first half of 2014

 

  • RHB-103 is a proprietary oral thin film formulation of rizatriptan, the active drug in Merck & Co.’s Maxalt MLT®

 

  • A U.S. New Drug Application (NDA) for RHB-103 is currently being reviewed by the FDA with a PDUFA goal date of February 3, 2014

 

TEL-AVIV, Israel, November 18, 2013 RedHill Biopharma Ltd. (Nasdaq: RDHL; TASE: RDHL) (the “Company” or “RedHill”), an emerging Israeli biopharmaceutical company focused primarily on the development and acquisition of late clinical-stage, proprietary formulations and combinations of existing drugs, today reported that the Company and its co-development partner, IntelGenx Corp. (“IntelGenx”), have recently concluded a positive European Scientific Advice meeting with the German Federal Institute for Drugs and Medical Devices (BfArM) regarding RHB-103, a proprietary, oral thin film formulation of rizatriptan for the treatment of acute migraine.

 

The Scientific Advice meeting with the BfArM provided sufficient clarity with regard to the regulatory path. Consequently, RedHill plans to conduct a small bioavailability study comparing RHB-103 to the European reference product.

 

RedHill previously conducted a successful bioequivalence trial which demonstrated the required U.S. Food and Drug Administration (FDA) criteria for therapeutic bioequivalence between the soluble oral thin film of RHB-103 and Merck & Co.’s Maxalt MLT®, the reference drug available in the U.S. In March 2013, following the successful bioequivalence study, RedHill submitted to the FDA a New Drug Application (NDA) seeking marketing approval of RHB-103. The FDA is currently conducting a substantive review of the NDA and has assigned a Prescription Drug User Fee Act (PDUFA) goal date of February 3, 2014.

 

Following the positive meeting with the BfArM, RedHill plans to complete the bioavailability study and submit a Marketing Authorization Application (MAA) for marketing approval of RHB-103 in Europe, with Germany as the reference member state under the European Mutual Recognition Procedure (MRP), during the first half of 2014.

 

"We are encouraged by the positive feedback we received from the German BfArM", said Dr. Reza Fathi, RedHill's Senior VP R&D. "We now plan to conduct a relatively short bioavailability study and we expect to file a European Marketing Authorization Application for RHB-103 during the first half of 2014." Dr. Fathi added; "If approved, RHB-103 will be an attractive new treatment option for migraine sufferers and physicians, with significant potential advantages. We are very excited by the upcoming FDA PDUFA date of February 3, 2014 for the U.S. New Drug Application and by the prospect of bringing RHB-103 to the European market."

 

RHB-103 is a proprietary oral thin film formulation of rizatriptan benzoate, a 5-HT1 receptor agonist and the active drug in Merck & Co.’s Maxalt®. Rizatriptan is considered one of the most effective oral triptans, a class of molecules that constrict blood vessels in the brain to relieve swelling and other migraine symptoms. The worldwide annual sales of triptans were estimated to have exceeded $1.6 billion in 2012[1], and the worldwide direct sales of Merck & Co.’s rizatriptan-based drugs exceeded $600 million in 2012[2].

 

RHB-103 is based on IntelGenx's proprietary “VersaFilm™” technology. The RHB-103 thin film strip dissolves rapidly in the mouth, leading to the absorption of the drug through the gastro intestinal track and into the bloodstream. The unique administration method of the RHB-103 thin film does not require the patient to swallow a pill or consume water, and presents a potentially attractive therapeutic alternative for many migraine patients, including those who suffer from migraine-related nausea - approximately 80% of the total migraine patient population[3].
