TEL-AVIV, Israel and RALEIGH, N.C., Sept. 04, 2018 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on proprietary drugs for gastrointestinal diseases, today announced that the last patient was enrolled in the confirmatory Phase III study with TALICIA® (RHB-105)1 for H. pylori infection (ERADICATE Hp2 study).
Top-line results from the study are expected to be announced before year’s end.
If successful, and subject to additional regulatory feedback, the ERADICATE Hp2 study is expected to complete the package required to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) for TALICIA® in early 2019.
TALICIA® was granted Qualified Infectious Disease Product (QIDP) designation by the FDA, providing Fast-Track Development, six months priority NDA review and eight years of U.S. market exclusivity. TALICIA® is intended to be the first product to be indicated for the treatment of H. pylori infection, regardless of ulcer status.
The two-arm, randomized, double-blind, active comparator confirmatory Phase III study compares TALICIA® against a dual therapy amoxicillin and omeprazole regimen at equivalent doses. The study enrolled 455 non-investigated dyspepsia patients with confirmed H. pylori infection in 55 clinical sites across the U.S. Subjects were randomized in a 1:1 ratio to receive four capsules, three times daily, of either TALICIA® or the active comparator, for a period of 14 days. Subjects are being assessed for the study’s primary endpoint of eradication of H. pylori infection at 43 through 71 days after initiation of treatment.
The first Phase III study with TALICIA® (ERADICATE Hp study) successfully met its primary endpoint of superiority over historical standard-of-care (SoC) eradication rate of 70%, with high statistical significance (p<0.001). The study results demonstrated 89.4% efficacy in eradicating H. pylori infection with TALICIA®. Notably, these results were also superior to subsequent open-label treatment with SoC therapies of patients in the placebo arm of the ERADICATE Hp study, which demonstrated 63% eradication rate (p=0.006), further supporting the potential efficacy of TALICIA®. Treatment with TALICIA® was shown to be safe and well tolerated.
About H. pylori:
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 worldwide2.
2015 worldwide and U.S. markets for H. pylori eradication therapies were estimated at approximately $4.83 billion and $1.45 billion, respectively3.
About TALICIA® (RHB-105):
TALICIA® (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 the 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. A first Phase III study with TALICIA® (ERADICATE Hp study) was completed in the U.S. with positive results. A confirmatory Phase III study (ERADICATE Hp2 study) is ongoing in the U.S. Additional studies may be required, subject to FDA review. TALICIA® is intended to be the first product indicated for the treatment of H. pylori infection in adults, regardless of ulcer status.
The ERADICATE Hp2 confirmatory Phase III study with TALICIA® (RHB-105) is registered on www.ClinicalTrials.gov, a web-based service of the U.S. National Institutes of Health (NIH), which provides access to information on publicly and privately supported clinical studies.
