- The U.S. Patent and Trademark Office (USPTO) has issued a Notice of Allowance for a new formulation patent application covering RHB-105 H. pylori bacterial infection treatment, to expire no earlier than 2034
- Top-line results from the ongoing Phase III study with RHB-105 are expected in June 2015
- RHB-105 targets a significantly broader indication than existing H. pylori therapies, as a first line treatment of H. pylori infection regardless of ulcer status, with the U.S. market for H. pylori eradication therapies estimated at approximately $1-1.5 billion annually
- RHB-105 has been granted a QIDP designation by the FDA under the GAIN Act, thus benefiting from Fast-Track development status, Priority Review of a potential New Drug Application (NDA) and additional five years of exclusivity, for a total of 8 years of market exclusivity
TEL-AVIV, Israel, April 16, 2015 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) (“RedHill”), an Israeli biopharmaceutical company primarily focused on late clinical-stage, proprietary, orally-administered drugs for inflammatory and gastrointestinal diseases, including gastrointestinal cancers, today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for U.S. Patent No. 14/179,197 covering the RHB-105 formulation. RHB-105 is a proprietary fixed-dose combination therapy of two antibiotics and a proton pump inhibitor (PPI), in an all-in-one oral capsule, targeting an indication of first line treatment of Helicobacter pylori (H. pylori) infection.
The new RHB-105 patent application is entitled “Pharmaceutical Compositions for the Treatment of Helicobacter Pylori”. Once granted, the patent is expected to be valid until at least 2034.
“This new patent application strengthens the RHB-105 intellectual property estate and extends patent protection until at least 2034.” said Guy Goldberg, RedHill’s Chief Business Officer. “RHB-105 is intended to overcome the growing resistance of H. pylori bacteria to standard antibiotic treatments, which results in increasing treatment failure rates. With the new patent protection and QIDP designation from the FDA, which extends the market exclusivity period to a total of 8 years, RHB-105 could be well positioned commercially in the H. pylori treatment market, if approved. We look forward to receiving top-line results from the ongoing Phase III study with RHB-105 in June 2015.”
RHB-105 is currently undergoing a first Phase III clinical study in the U.S. (the ERADICATE Hp study). The randomized, placebo-controlled study is intended to evaluate the safety and efficacy of RHB-105 as a first-line treatment for confirmed H. pylori bacterial infection, a major cause of chronic gastritis, peptic ulcer disease, gastric cancer, and mucosa associated lymphoid tissue (MALT) lymphoma. Top-line data from the Phase III study is expected in June 2015.
With RHB-105, RedHill is pursuing an indication of first line treatment of H. pylori infection regardless of ulcer status, a significantly broader indication than current standard treatments for H. pylori, which are typically limited and indicated to treat patients with an active or recent history of ulcers. If approved, RHB-105 may be the first H. pylori eradication therapy to target this broader indication, which would significantly expand the potential patient population on the label for this drug.
In November 2014, the U.S Food and Drug Administration (FDA) designated RHB-105 as a Qualified Infectious Disease Product (QIDP) under the FDA’s Generating Antibiotic Incentives Now (GAIN) Act, which is intended to encourage new antibiotic drugs for the treatment of serious or life-threatening infections. The designation allows RedHill to benefit from Fast-Track development status for RHB-105, providing for an expedited development pathway as well as Priority Review status, potentially leading to a shorter review time by the FDA of a New Drug Application (NDA), if filed. If approved, RHB-105 will also receive an additional five years of U.S. market exclusivity on top of the standard exclusivity period, for a total of 8 years of market exclusivity.
It is estimated that approximately two-thirds of the world’s population is infected with H. pylori, and the potential market of H. pylori eradication therapies in the U.S. is estimated at approximately $1-1.5 billion annually1.
About RHB-105:
RHB-105 is a new and proprietary fixed-dose oral combination therapy of two antibiotics and a proton pump inhibitor (PPI) in an all-in-one oral capsule with a planned indication for treatment of H. pylori infection. H. pylori bacterial infection is a major cause of chronic gastritis, peptic ulcer disease, gastric cancer, and mucosa associated lymphoid tissue (MALT) lymphoma. RHB-105 is currently undergoing a first Phase III clinical study in the U.S. (named ERADICATE Hp) planned to be followed, if successful, by a second Phase III study. RHB-105 has been granted Qualifying Infectious Disease Product (QIDP) designation by the FDA, providing for a Fast Track development pathway as well as Priority Review status, potentially leading to a shorter review time by the FDA of a New Drug Application (NDA), if filed. If approved, RHB-105 will also receive an additional five years of U.S. market exclusivity on top of the standard exclusivity period, for a total of 8 years of market exclusivity.
