TEL-AVIV, Israel, April 24, 2017 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (RDHL) (Tel-Aviv Stock Exchange: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 enrollment of the last patient in the Phase II study with BEKINDA® (RHB-102)1 12 mg for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D).
BEKINDA® is a proprietary, bimodal extended-release, once-daily oral pill formulation of ondansetron, targeting several gastrointestinal indications.
The randomized, double-blind, placebo-controlled Phase II study is evaluating the safety and efficacy of BEKINDA® 12 mg in adults over the age of 18 with IBS-D. The study enrolled 127 subjects in 16 U.S. clinical sites. Top-line results are expected in the third quarter of 2017.
Subjects enrolled in the Phase II IBS-D study were randomized 60:40 to receive either BEKINDA® 12 mg or a placebo, once daily, for a period of eight weeks. The primary endpoint for the study is the proportion of patients in each treatment group with response in stool consistency as compared to baseline, per FDA guidance definition. Secondary endpoints include the proportion of patients in each treatment group who are pain responders and the proportion of patients in each treatment group who are responders to the combined endpoints of stool consistency and pain, per FDA guidance definition.
IBS is one of the most common gastrointestinal disorders2. It is estimated that at least 30 million Americans suffer from IBS3, of which over 40% are cases of IBS-D4. The U.S. potential market for IBS-D treatments is estimated to exceed $1 billion by 20225.
5-HT3 antagonists such as ondansetron, the active pharmaceutical ingredient in BEKINDA®, have been shown to slow intestinal transit time in humans6. Alosetron (Lotronex®), a 5-HT3 antagonist of the same class of drugs as ondansetron, has been approved by the FDA for the treatment of women with severe chronic IBS-D, but is under a restricted prescribing (REMS) program due to potential severe side effects7. Ondansetron, approved by the FDA as an oncology support antiemetic, has demonstrated activity in IBS-D in preliminary studies8 and, in light of its safety profile, RedHill believes that BEKINDA®, if approved, has the potential to be a preferred once-daily treatment for a broad segment of patients suffering from IBS-D.
Top-line results from the Phase III study with BEKINDA® 24 mg for acute gastroenteritis and gastritis (the GUARD study) are expected in the second quarter of 2017. In February 2017, RedHill announced that the last patient had completed the treatment course and observation period in the randomized, double-blind, placebo-controlled GUARD study, which treated 320 adults and children over the age of 12 in 29 U.S. clinical sites.
The Phase II study and the Phase III GUARD study with BEKINDA® are registered on www.ClinicalTrials.gov, a web-based service of the U.S. National Institutes of Health, which provides access to information on publicly and privately supported clinical studies.
