RedHill Biopharma (RDHL) Announces New USPTO Patent Covering Talicia Through 2034

RedHill Biopharma Ltd. (NASDAQ: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the issue of a new U.S. patent covering Talicia¹ as an all-in-one fixed-dose combination of amoxicillin, omeprazole and rifabutin and its use for the treatment of helicobacter pylori (H. pylori) infection (Patent No. 11,931,463 to be issued March 19, 2024⁴). Talicia is the leading branded first-line therapy prescribed by U.S. gastroenterologists for H. pylori infection, which affects approximately 35% of the U.S. adult population and this patent is expected to provide protection for Talicia until February 12, 2034.

"Talicia is the only FDA-approved rifabutin-containing all-in-one therapy for the eradication of H. pylori. Its components and formulation are optimized to provide patients with the right medications for successful H. pylori eradication with an optimized resistance profile, which is significant in the face of growing microbial resistance to clarithromycin-based regimens," said Patricia Anderson, RedHill's Senior Vice President of Regulatory Affairs. "The granting of this new U.S. patent further adds to the strong intellectual property protecting Talicia, including the recently announced patent for treatment regardless of patient Body Mass Index (BMI), several other composition of matter and other patents, and additional FDA-granted data exclusivities granted under the Generating Antibiotic Incentives Now (GAIN) Act Qualified Infectious Disease Product (QIDP) designation and the approval of Talicia under section 505(b)(2)."

About H. pylori infection
H. pylori is a bacterial infection that affects approximately 35% of the U.S. population, with an estimated two million patients treated annually⁵. Worldwide, more than 50% of the population has H. pylori infection, which is classified by the World Health Organization (WHO) as a Group 1 carcinogen. It remains the strongest known risk factor for gastric cancer⁶ and a major risk factor for peptic ulcer disease⁷ and gastric mucosa-associated lymphoid tissue (MALT) lymphoma⁸. More than 27,000 Americans are diagnosed with gastric cancer annually⁹. Eradication of H. pylori is becoming increasingly difficult, with current therapies failing in approximately 25-40% of patients who remain H. pylori-positive due to high resistance of H. pylori to antibiotics – especially clarithromycin – which is still commonly used in standard combination therapies.
