- The Phase III study is expected to commence in the U.S. by the end of this month
- RHB-105 is a new and proprietary combination therapy in an oral capsule for the treatment of
pylori bacterial infection
- RedHill recently commenced another Phase III study in the U.S. with RHB-104 for the treatment of Crohn’s disease
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, announced today that the U.S. Food and Drug Administration (FDA) has accepted its Investigational New Drug (IND) application for the ERADICATE Hp study - a Phase III clinical study with RHB-105 for the treatment of Helicobacter pylori (H. pylori) bacterial infection. The Company plans to commence the Phase III study in the U.S. by the end of this month, subject to final preparations.
The RHB-105 IND acceptance follows a pre-IND meeting held with the FDA in October 2012 and subsequent communications between the Company and the FDA throughout the past year.
RHB-105 is a new and proprietary combination therapy of two antibiotics and a PPI (proton pump inhibitor), in an 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.
Existing standard of care combination therapies for H. pylori infection have high failure rates due to 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 demonstrated superior resistance profile, and offers a new and potentially improved therapeutic alternative with increased efficacy in eradicating H. pylori infection.
A Phase II study conducted in Australia with the RHB-105 active agents demonstrated an eradication rate greater than 90% in patients who had previously failed at least one course of standard of care therapy for 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 overall patient compliance and response.
It is estimated that approximately two-thirds of the world's population is infected with H. pylori, and one of ten Americans will suffer from peptic ulcer disease during their lifetime. The sales of
H. pylori eradication therapies in the U.S. are estimated at approximately $1-1.5 billion annually.
- Reza Fathi, RedHill's Senior VP R&D, commented: "The acceptance of the RHB-105 IND application is another major regulatory milestone for RedHill and an important validation of our clinical development program. Current standard therapies for H. pylori eradication have high failure rates due to growing resistance. Based on the results from a prior Phase II study, we believe that RHB-105 has the potential to become a preferred treatment for H. pylori infection. We are now focused on completing final preparations for the Phase III ERADICATE Hp study with RHB-105, which we expect to commence in the U.S. by the end of this month."
RHB-105 is one of RedHill’s leading gastrointestinal (GI) late clinical-stage development programs. The Company announced earlier this month the initiation of the MAP US study - a Phase III clinical study designed to evaluate the safety and efficacy of fixed-dose RHB-104 for the treatment of Crohn's disease. RHB-104 is a proprietary and potentially groundbreaking combination antibiotic therapy in an oral capsule. The randomized, double-blind, placebo-controlled Phase III MAP US clinical study is expected to enroll 240 subjects with moderately to severely active Crohn's disease in approximately 50 clinical sites in the U.S., Canada and Israel.
