RedHill Biopharma Announces First Patients Dosed in Phase III Study of RHB-105 for H. pylori Infection
- The first patients have been dosed in the ERADICATE Hp study - a randomized, double-blind, placebo-controlled, Phase III study evaluating RHB-105 as a first-line therapy for pylori bacterial infection
- Seven of the eight clinical sites in the U.S. are actively enrolling patients, with the last site expected to commence enrollment shortly; the Phase III data is expected by the third quarter of 2014
- Approximately two-thirds of the world's population is infected with pylori, a major cause of chronic gastritis, peptic ulcer disease and gastric cancer; existing therapies have increasing failure rates due to bacterial resistance
- RedHill recently commenced dosing in a Phase III study with a different drug, RHB-104, for Crohn’s disease, another inflammatory disease of the gastrointestinal system
TEL-AVIV, Israel, December 17, 2013 RedHill Biopharma Ltd. (Nasdaq: RDHL; TASE: RDHL) (the “Company” or “RedHill”), an emerging Israeli biopharmaceutical company focused primarily on the development and acquisition of late clinical-stage, proprietary formulations and combinations of existing drugs, today announced that the first patients have been dosed in the Phase III ERADICATE Hp clinical study in the U.S.
The Phase III ERADICATE Hp clinical study is designed to evaluate the safety and efficacy of
RHB-105 as a first-line treatment for confirmed Helicobacter pylori (H. pylori) bacterial infection, a major cause of chronic gastritis, peptic ulcer disease, gastric cancer and mucosa associated lymphoid tissue (MALT) lymphoma. Seven of the eight clinical sites in the U.S. have commenced enrollment of patients for the ERADICATE Hp study, and the last site is expected to commence enrollment shortly.
"We are very excited by the dosing of the first patients in the Phase III study with RHB-105 for the treatment of H. pylori infection. We believe RHB-105 is a potential solution to the growing bacterial resistance and high failure rates of currently available therapies," said Dr. Reza Fathi, RedHill's Senior VP R&D. Dr. Fathi continued, "A previous Phase II study conducted with the
RHB-105 combination demonstrated an eradication rate of more than 90% in patients who had previously failed standard of care therapy. This positive data leads us to believe that, if approved, RHB-105 could become the preferred first line therapy for H. pylori infection. Considering that per patient treatment is only 14 days, we expect data from the ongoing Phase III study to be available by the third quarter of 2014."
Existing standard of care combination therapies for H. pylori infection have increasingly high failure rates due to the growing resistance of H. pylori to the antibiotics commonly used in such therapies. RHB-105 is composed of a different combination of antibiotics, specifically selected due to their potential for improved efficacy and superior resistance profile for eradicating H. pylori infection.
In addition to a potential increase in efficacy, RHB-105’s new and proprietary all-in-one oral capsule formulation offers a convenient treatment regimen, potentially improving patient compliance and convenience.
The randomized, double-blind, placebo-controlled, Phase III study is expected to enroll 90
non-investigated dyspepsia subjects with confirmed H. pylori infection in 8 clinical sites in the U.S. Subjects are randomized in a 2:1 ratio to receive four capsules three times daily of either RHB-105 or placebo for a period of 14 days, and are assessed for the study's primary endpoint of eradication of H. pylori infection 28 to 56 days after completion of treatment.
The ERADICATE Hp study is registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies.
It is estimated that approximately two-thirds of the world's population is infected with H. pylori, and approximately 500,000 Americans suffer from peptic ulcer disease annually, which is caused by H. pylori bacterial infections. The market of H. pylori eradication therapies in the U.S. is estimated at approximately $1-1.5 billion annually.
The Company announced in November 2013 that it had commenced dosing in the MAP US study, a Phase III study with RHB-104 - another proprietary antibiotic therapy. RHB-104 is intended for the treatment of Crohn’s disease, which, similar to H. pylori, is an inflammatory condition of the gastrointestinal system. Crohn's disease is a condition with significant unmet medical needs.
RHB-104 is a combination antibiotic therapy in oral capsule formulation, with potent intracellular, antimycobacterial and anti-inflammatory properties. It is a potentially groundbreaking therapy that targets the suspected underlying cause of the disease, based on increasing evidence supporting the hypothesis that Crohn’s disease is caused by the Mycobacterium avium subspecies paratuberculosis (MAP) infection in susceptible patients.
About RHB-105 :
RHB-105 is a new and proprietary fixed-dose combination therapy of two antibiotics and a proton pump inhibitor (PPI), in an all-in-one oral capsule, designed for the treatment of H. pylori bacterial infection - a major cause of chronic gastritis, peptic ulcer disease, gastric cancer and mucosa associated lymphoid tissue (MALT) lymphoma. The RHB-105 combination was originally developed by Professor Thomas Borody, a leading innovator of therapeutic approaches to gastrointestinal tract diseases, who developed the first approved triple therapy treatment for H. pylori associated with peptic ulcer disease.
