TEL-AVIV, Israel / RALEIGH, NC, September 12, 2018 -- RedHill Biopharma Ltd. (NASDAQ: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on proprietary drugs for gastrointestinal diseases, today announced that it recently concluded a positive End-of-Phase II/Pre-Phase III (Type B) meeting with the U.S. Food and Drug Administration (FDA) discussing the clinical and regulatory pathway towards potential U.S. approval of BEKINDA® (RHB-102)1 for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D).

In light of the clarity provided by the FDA, RedHill plans to finalize the design of two pivotal Phase III studies with BEKINDA® and to accelerate global pharma partnership discussions, including U.S. co-promotion opportunities.  

The FDA meeting followed the positive results of the randomized, double-blind, placebo-controlled Phase II study with BEKINDA® for IBS-D. The study, which was conducted in the U.S. and enrolled 126 subjects, successfully met its primary endpoint, improving the primary efficacy outcome of stool consistency response (per FDA guidance definition) by an absolute difference of 20.7% vs. placebo (p = 0.036). Results from the Phase II study suggest that they compare favorably with previously reported efficacy outcome values from studies of Xifaxan® (rifaximin) and Viberzi® (eluxadoline) across all three efficacy endpoints2.

Gilead Raday, RedHill’s chief operating officer, said: “We are very pleased with the outcome of our meeting with the FDA, which provided clarity on the planned endpoints as well as other important aspects for the design of the pivotal Phase III studies to support potential NDA filing. We believe BEKINDA® could become a leading safe and effective therapy for IBS-D patients and plan to accelerate global pharma partnership discussions, including U.S. co-promotion opportunities.”

IBS is one of the most common gastrointestinal disorders3, affecting an estimated 30 million Americans, of which approximately 40% are estimated to be cases of IBS-D4. The U.S. market of IBS-D therapies grew by approximately 550% between 2013-20165.

In addition, RedHill is currently in discussions with the FDA on the design of a confirmatory Phase III study with BEKINDA® for acute gastroenteritis, following the positive results from the first Phase III study.

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

Xifaxan® (rifaximin) prescribing information:; Viberzi® (eluxadoline) prescribing information:; 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.
