TEL-AVIV, Israel and RALEIGH, N.C., May 30, 2018 (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 drugs for gastrointestinal diseases, today announced a presentation of Phase II results of  BEKINDA® for diarrhea-predominant irritable bowel syndrome (IBS-D) at Digestive Disease Week® (DDW) 2018, being held June 2-5 in Washington, DC.

The poster1 (abstract number: Su1188), entitled ‘Randomized, double-blind, placebo-controlled, Phase 2 trial of ondansetron 12 mg bimodal release tablets for diarrhea-predominant irritable bowel syndrome (IBS-D)’, was selected as a poster of distinction and for highlighting in an oral presentation at DDW 2018.

Data from the poster will be presented by Dr. Terry F. Plasse, Medical Director at RedHill, as part of the IBS ePoster tour on Monday, June 4, 2018, at 12:00 PM EDT, at the DDW 2018 ePosters Theater. ePosters tours, curated by society experts, highlight the latest science featured in the Poster Hall in a small theater setting. The poster will also be presented for general viewing on Sunday, June 3, 2018, from 12:00 PM to 2:00 PM EDT in Hall C, at Walter E. Washington Convention Center, Washington, DC.

The abstract describes positive results of the Phase II study with BEKINDA® (RHB-102)2 12 mg for IBS-D. The Phase II study with BEKINDA® 12 mg successfully met its primary endpoint, improving the primary efficacy outcome of stool consistency (per FDA guidance definition) by an absolute difference of 20.7% vs. placebo (p-value=0.036). Results from the BEKINDA® Phase II study suggest that they compare favorably with previously reported efficacy outcome values from studies with Xifaxan® (rifaximin) and Viberzi® (eluxadoline) across all three efficacy endpoints3. RedHill plans to meet with the FDA in the third quarter of 2018 to discuss the design for possible pivotal Phase III studies with BEKINDA® 12 mg for IBS-D.

About BEKINDA® (RHB-102):     
BEKINDA® is a proprietary, bimodal extended-release (24 hours) oral pill formulation of ondansetron, covered by several issued and pending patents and targets several gastrointestinal indications. A first Phase III clinical study with BEKINDA® 24 mg for the treatment of acute gastroenteritis and gastritis (the GUARD study) successfully met its primary endpoint. A Phase II study with BEKINDA® 12 mg for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) successfully met its primary endpoint.

Xifaxan® (rifaximin) prescribing information: www.accessdata.fda.gov/drugsatfda_docs/label/2010/022554lbl.pdf; Viberzi® (eluxadoline) prescribing information: www.accessdata.fda.gov/drugsatfda_docs/label/2015/206940s000lbl.pdf; Average absolute difference from reported Phase III studies; the theoretical comparison between the BEKINDA® 12 mg Phase II study results and reported data from studies of IBS-D-approved therapies serves as a general benchmark for the effect size observed with BEKINDA® 12 mg and should not be construed as a direct and/or equal comparison given that the studies were not identical in design, patient population and treatment period. For example, in the Xifaxan® 550 mg Phase III studies, the referenced efficacy endpoints were evaluated over a period of 4 weeks after 2 weeks drug administration, and in the Viberzi® 100 mg Phase III studies the referenced efficacy endpoints were evaluated after drug was administered and evaluated for 12 weeks. The studies were not conducted head-to head in the same patient population.
