TEL-AVIV, Israel, Jan. 03, 2017 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (NASDAQ:RDHL) (TASE:RDHL) (“RedHill” or the “Company”), 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 the signing of an exclusive co-promotion agreement with a subsidiary² of Concordia International Corp. (NASDAQ:CXRX) (TSX:CXR) (“Concordia”), an international specialty pharmaceutical company focused on generic and legacy pharmaceutical products and orphan drugs, granting RedHill certain U.S. promotion rights for Donnatal^®, a prescription oral drug used with other drugs in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis (inflammation of the small bowel)³.

Under the terms of the agreement, RedHill will be responsible for certain promotional activities related to Donnatal^®. Concordia will continue to be responsible for the manufacturing and supply of Donnatal^® in all territories. Donnatal^® accounted for 7.7% of Concordia’s consolidated revenues in the first half of 2016⁴. RedHill and Concordia will share the revenues generated from the promotion of Donnatal^® by RedHill based on an agreed upon split between them. The initial term of the co-promotion agreement with Concordia is for three years. RedHill expects to initiate gradual promotion of Donnatal^® in the coming months.

Dror Ben-Asher, Chief Executive Officer of RedHill, said: “We are pleased to partner with Concordia for the U.S. promotion of Donnatal^®, a trusted brand among physicians for symptoms of IBS and acute enterocolitis⁵. With a core U.S. commercial team in place, we plan to initiate promotional activities in the U.S. in the coming months with a specialty gastrointestinal sales force. RedHill’s strategic transition into a revenue-generating, gastrointestinal-focused, specialty pharmaceutical company with commercial presence in the U.S., is planned to support potential future commercialization of our Phase III-stage potential blockbusters BEKINDA^® for gastroenteritis and other GI indications, RHB-105 for H. pylori infection and RHB-104 for Crohn’s disease, if approved by FDA.”

“This agreement is a cost-effective approach to promoting Donnatal^® in a manner consistent with our long-term strategic focus on operational excellence,” said Allan Oberman, Chief Executive Officer of Concordia. “RedHill’s commercial team is highly motivated and has previous experience in gastroenterology sales. We look forward to partnering with them to market Donnatal^® to more key prescribers who we believe can help raise the product’s profile and potentially allow us to reach more patients in the U.S.”

About IBS:
Irritable bowel syndrome (IBS) is a chronic multifactorial disorder characterized by recurrent abdominal pain or discomfort associated with altered bowel function. Certain factors that may alter gastrointestinal function can contribute to IBS symptoms, including stress, prior gastroenteritis and changes in the gut microbiome. However, the etiology of IBS is not understood and the underlying cause of IBS remains unknown. IBS negatively impacts patients’ quality of life and can affect patients physically, emotionally, socially and economically. IBS is one of the most common gastrointestinal disorders. It is estimated that at least 30 million Americans suffer from IBS⁶. The U.S. potential market for IBS treatments is estimated to exceed $2.3 billion by 2020⁷. Studies estimate that IBS affects 10 to 15 percent of U.S. adults, with about twice as many women as men and most often occurs in people younger than age 45⁸.

About Donnatal^®:
Donnatal^® (Phenobarbital, Hyoscyamine Sulfate, Atropine Sulfate, Scopolamine Hydrobromide), a prescription drug, is classified as possibly effective as an adjunctive therapy in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis. Donnatal^® slows the natural movements of the gut by relaxing the muscles in the stomach and intestines and acts on the brain to produce a calming effect. Donnatal^® comes in two formulations: immediate release Donnatal^® Tablets, and immediate release Donnatal^® Elixir, a fast acting liquid.

Donnatal^® is contraindicated in patients who have glaucoma, obstructive uropathy, obstructive disease of the gastrointestinal tract, paralytic ileus, unstable cardiovascular status, severe ulcerative colitis, myasthenia gravis, hiatal hernia with reflux esophagitis, or known hypersensitivity to any of the ingredients.  Patients who are pregnant or breast-feeding or who have autonomic neuropathy, hepatic or renal disease, hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, tachycardia or hypertension should notify their doctor before taking Donnatal^®. Side effects may include: dryness of the mouth, urinary retention, blurred vision, dilation of pupils, rapid heartbeat, loss of sense of taste, headache, nervousness, drowsiness, weakness, dizziness, insomnia, nausea, vomiting, and allergic reactions which may be severe.
