Published on: Jan 11, 2017

RedHill Biopharma Ltd. (NASDAQ:RDHL) (TASE: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, announced first dosing in a three-way crossover pharmacokinetic (PK) study with RHB-105 in 18 subjects (healthy volunteers), intended to evaluate the bioavailability of RHB-105 actives versus the comparator in the planned confirmatory Phase III study (dual therapy of amoxicillin and omeprazole) and a food-effect study with RHB-105.

The first group of subjects have been dosed in a single-dose three-way crossover pharmacokinetic (PK) study with RHB-105 versus the active comparators in the confirmatory Phase III study and in a food-effect study with RHB-105 in healthy volunteers.

The confirmatory Phase III study with RHB-105 for H. pylori infection is planned to be initiated, subject to regulatory approvals and completion of the supportive PK program, by April of this year.

Subject to a successful outcome, the confirmatory Phase III study and the supportive PK program are expected to complete the package required for a U.S. NDA for RHB-105.

The first Phase III study with RHB-105 successfully demonstrated 89.4% efficacy in eradicating H. pylori infection (p<0.001), supporting the potential superior efficacy of RHB-105 over current standard-of-care (SoC) therapies.

RHB-105 was granted QIDP designation by the FDA under the GAIN Act, including Fast-Track development, NDA Priority Review and extended U.S. market exclusivity, for a total of eight years.

H. pylori bacterial infection is a major cause of chronic gastritis, peptic ulcer disease, gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma and is estimated to affect over half of the adult population worldwide.

The 2015 global and U.S. market potential for H. pylori eradication therapies at current branded prices, were estimated at approximately $4.83 billion and $1.45 billion, respectively.
