    RedHill Biopharma Announces Final Results from Phase II Study with BEKINDA® for IBS-D

    TEL-AVIV, Israel and RALEIGH, N.C., Jan. 16, 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 and cancer, today announced top-line final results1 from the Phase II clinical study with BEKINDA® 12 mg (RHB-102)2 for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D).

    • An independent review and analysis of the final results, provided to the Company, confirmed that 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). The final top-line results improve upon the previously announced top-line results (absolute difference of 19.4%, p-value=0.05).
       
    • Results from the BEKINDA® 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 endpoints3.

    • The randomized, double-blind, placebo-controlled Phase II study evaluated the efficacy and safety of BEKINDA® 12 mg in 126 subjects over 18 years old in the U.S., who received either BEKINDA® 12 mg or placebo, once daily, for a period of eight weeks.

    • IBS is one of the most common gastrointestinal disorders4, affecting an estimated 30 million Americans, of which approximately 40% are estimated to be cases of IBS-D5; The U.S. market of IBS-D therapies grew by approximately 550% between 2013-20166.

    • RedHill plans to meet with the FDA in the first half of 2018 to discuss the design for one or two pivotal Phase III studies with BEKINDA® 12 mg for IBS-D.

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.
