RedHill Biopharma Announces Publication of RHB-102 Gastroenteritis Phase 3 Study Results in JAMA

November 12, 2019

TEL-AVIV, Israel and RALEIGH, N.C., Nov.12, 2019 RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on the commercialization and development of proprietary drugs for the treatment of gastrointestinal diseases, today announced the publication of results from the Company’s Phase 3 study with RHB-102 (Bekinda®)1 in acute gastroenteritis (the GUARD study) in the Journal of the American Medical Association (JAMA) Network Open.

The article2, entitled “Bimodal Release Ondansetron for Acute Gastroenteritis Among Adolescents and Adults” became available online as an open-access article on November 8, 2019, JAMA Netw Open. 2019;2(11):e1914988. doi:10.1001/jamanetworkopen.2019.14988

The article describes the positive results from the first Phase 3 study with RHB-102 (Bekinda) in acute gastroenteritis. The double-blind, placebo-controlled, parallel-group randomized trial treated subjects ages 12 years and older who presented with frequent vomiting resulting from acute gastroenteritis. The clinical study was conducted in 21 emergency and urgent care departments in the United States.

The GUARD study met its primary endpoint, prevention of further vomiting for at least 24 hours among adolescents and adults with gastroenteritis-related emesis without the usage of intravenous hydration or rescue medication. Further, the results demonstrated that RHB-102 (Bekinda) is well tolerated and can be safely administered to patients with acute gastroenteritis. The authors conclude that orally-administered RHB-102 (Bekinda) is an effective antiemetic among adolescents and adults with moderate to severe vomiting from acute gastroenteritis and that it may decrease the need for intravenous hydration, or medication and emergency department care to manage acute gastroenteritis. 

RHB-102 (Bekinda) is a proprietary, oral, bimodal-release (24 hours), once-daily pill formulation of ondansetron, a drug that prevents vomiting by blocking certain effects of serotonin. Acute gastroenteritis and gastritis are inflammations of the gastrointestinal tract, most commonly caused by a viral infection. Symptoms of gastroenteritis include nausea, vomiting, diarrhea, and abdominal pain. The GUARD study was designed to determine if  Bekinda can prevent the need for intravenous (IV) hydration or IV drugs by relieving the vomiting. Bekinda is unique in that it releases drug quickly after administration for fast symptom relief and has a slow-acting matrix that allows the preparation to have a therapeutic effect for up to 24 hours.

RedHill is currently working toward a confirmatory Phase 3 study to support a potential New Drug Application (NDA) for RHB-102 (Bekinda) for the treatment of acute gastroenteritis and gastritis.

RedHill is also developing RHB-102 (Bekinda) in a different dosage for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) and is currently finalizing the design of two pivotal Phase 3 studies for IBS-D.
