TEL-AVIV, Israel and RALEIGH, N.C., Nov. 01, 2017 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (NASDAQ:RDHL) (Tel-Aviv Stock Exchange:RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company primarily focused on late clinical-stage development and commercialization of proprietary, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, together with IntelGenx Corp. (TSX-V: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(TM) technology platform, today announced that they have resubmitted the 505(b)(2) New Drug Application (NDA) for RIZAPORT® 10mg to the U.S. Food and Drug Administration (FDA).

RIZAPORT® is a proprietary oral thin-film formulation of rizatriptan for the treatment of acute migraines. RIZAPORT® offers an innovative 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 NDA submission to the FDA in March 2013, RedHill and IntelGenx received a Complete Response Letter (CRL) from the FDA. The questions raised by the FDA, which triggered the current resubmission, primarily related to third party chemistry, manufacturing and controls (CMC) and to the packaging and labeling of the product. The FDA letter 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 permits a full review by the FDA, a Prescription Drug User Fee Act (PDUFA) date is expected to be set by the FDA for the first half of 2018.

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."

"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."

RIZAPORT® was granted marketing authorization in Germany and in Luxembourg on the basis of the European Decentralized Procedure (DCP). A national Marketing Authorization Application (MAA) has been submitted for RIZAPORT® in Spain. Under the European DCP, marketing authorization approval of RIZAPORT® in additional European countries is subject to a separate procedure to obtain additional national marketing authorizations in each country. A first commercialization agreement for RIZAPORT®was signed with Grupo JUSTE S.A.Q.F. (now Exeltis Healthcare, S.L.) for Spain, and a second commercialization agreement for RIZAPORT® was signed with Pharmatronic Co. for South Korea.

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 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 (TM)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 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 population1 and patients suffering from dysphagia (difficulty swallowing)1.

Pittsburgh, PA, Jan. 17, 2019 (GLOBE NEWSWIRE) -- Calgon Carbon Corporation today announced a global price increase, effective February 1, 2019, where contracts permit, on all activated carbon products and related equipment due to a continued escalation in raw material costs and transportation expenses.

Taconic Biosciences’ Animals Complete Most Recent Mission to the International Space Station17.1.2019 15:29Pressemelding

RENSSELAER, N.Y., Jan. 17, 2019 (GLOBE NEWSWIRE) -- Taconic Biosciences, a global leader in providing genetically engineered rodent model solutions, announces the completion of a recent mission to the International Space Station. This project represents a collaboration between the International Space Station (ISS) National Lab, National Aeronautics and Space Administration (NASA), Bioserve Space Technologies with support from the Leidos Corporation, and Taconic. Taconic has participated in several spaceflight missions with NASA since 1985. Most recently, as part of the science and research investigation payloads supported by the SpaceX Commercial Resupply Services missions, Taconic prepared mice to live aboard the International Space Station for extended periods.

Therefore, mice exposed to microgravity via spaceflight are a valuable model to understand and devel

MPP Global Bridges the Innovation Gap by Centralising Physical and Digital Subscriber Management and Billing in a Single Cloud Platform17.1.2019 12:29Pressemelding

WARRINGTON, UK, Jan. 17, 2019 (GLOBE NEWSWIRE) -- MPP Global, the technology company that delivers eSuite, the world’s smartest subscriber management & billing platform, announces the launch of pivotal new functionality which enables media organisations to seamlessly create and manage the sale of physical subscriptions. This positions eSuite as the complete physical and digital subscription management solution. The development of this industry-first functionality was borne out of the common challenge for publishers when managing multiple systems for deploying bundled print and digital subscriptions. This is inflexible for publishers and limits choice for their customers, restricting the ability to seamlessly create and offer digital and print subscription bundles. Despite increased consumer uptake of digital subscriptions, print still accounts for almost 90% of circulation revenues globally. To drive reader revenues successfully, publishers require functionality to execute complementar
