IntelGenx Corp. (TSX VENTURE:IGX)(OTCQX:IGXT) (“IntelGenx”), a leading oral drug delivery company primarily focused on the development and manufacturing of innovative pharmaceutical oral films based on its proprietary VersaFilm™ technology platform, together with RedHill Biopharma Ltd. (NASDAQ:RDHL)(TASE:RDHL) (“RedHill”), a specialty biopharmaceutical company primarily focused on the development and commercialization of late clinical-stage, proprietary, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, today announced that they have resubmitted the 505(b)(2) New Drug Application (“NDA”) to the U.S. Food and Drug Administration (“FDA”) for RIZAPORT® 10 mg.
RIZAPORT® is a proprietary oral thin-film formulation of rizatriptan for the treatment of acute migraines. RIZAPORT® offers an innovative and potentially advantageous therapeutic alternative for many migraine patients, primarily patients who suffer from dysphagia or migraine-related nausea, due to its convenient dosing, facile intake due to the lack of need for water, and neutral flavor.
Following a first RIZAPORT® NDA submission to the FDA in March 2013, IntelGenx and RedHill received a Complete Response Letter (“CRL”) from the Agency. The questions raised by the FDA, which triggered the current resubmission, primarily related to third party chemistry, manufacturing and controls, and the packaging and labeling of the product. The FDA raised no questions or deficiencies relating to RIZAPORT®’s safety and bio-equivalence data and did not require additional clinical trials.
If the RIZAPORT® NDA resubmission is deemed complete and permitted a full review by the FDA, a Prescription Drug User Fee Act (“PDUFA”) date is expected to be set by the Agency for the first half of 2018.
“This resubmission of the RIZAPORT® 505(b)(2) NDA is an important milestone for IntelGenx,” commented Dr. Horst G. Zerbe, President and CEO of IntelGenx. “We look forward to continuing to work with the FDA as we seek to bring this product to market as a new therapeutic option for the benefit of patients suffering from migraines.”
Reza Fathi, PhD, RedHill’s Senior VP Research & Development, said, “We are very pleased with the resubmission of the U.S. NDA for RIZAPORT®, which follows the marketing authorization received for RIZAPORT® in Germany and Luxembourg under the European Decentralized Procedure. Our efforts are focused on commercializing RIZAPORT® through partners in the U.S., Europe and other territories in the near future, and we are continuing the dialogue with potential partners.”
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 and in Luxembourg in April 2017 under the European Decentralized Procedure. A New Drug Application for RIZAPORT® was resubmitted to the U.S. FDA in October 2017. RedHill 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. 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 soluble film, which does not require the patient to swallow a pill or consume water, along with its neutral 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 and patients suffering from dysphagia (difficulty swallowing)1.
