U.S. Patent and Trademark Office (USPTO) issues new patent covering Talicia1 as an all-in-one treatment of Helicobacter pylori (H. pylori), supporting Talicia protection until February 12, 2034 This new patent adds to the existing strong intellectual property portfolio protecting Talicia, including composition of matter and other patents and FDA-granted data exclusivities granted under the GAIN QIDP designation and section 505(b)(2) Talicia is the only FDA-approved rifabutin-containing all-in-one therapy for the eradication of H. pylori, providing an optimized antibiotic resistance profile and the leading branded first-line therapy prescribed by U.S. gastroenterologists2 for H. pylori infection, which affects approximately 35% of the U.S. adult population3 TEL AVIV, Israel and RALEIGH, N.C., March 11, 2024 /PRNewswire/ -- 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. About Talicia Talicia is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (PPI) (omeprazole), approved by the U.S. Food and Drug Administration (FDA) for the treatment of H. pylori infection in adults. Talicia is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address H. pylori's high resistance to other antibiotics. The high rates of H. pylori resistance to clarithromycin have led to significant rates of treatment failure with clarithromycin-based therapies and are a strong public health concern, as highlighted American College of Gastroenterology, the FDA and the WHO in recent years. In the pivotal Phase 3 study, Talicia demonstrated 84% eradication of H. pylori infection in the intent-to-treat (ITT) group vs. 58% in the active comparator arm (p<0.0001). Minimal to zero resistance to rifabutin, a key component of Talicia, was detected in RedHill's pivotal Phase 3 study. Further, in an analysis of data from this study, it was observed that subjects who were confirmed adherent10 to their therapy had response rates of 90.3% in the Talicia arm vs. 64.7% in the active comparator arm11. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Talicia and other antibacterial drugs, Talicia should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. Talicia is eligible for a total of eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents which extend patent protection until 2034 with additional patents and applications pending and granted in various territories worldwide.

The U.S. government's Chemical Medical Countermeasures (Chem MCM) Program and Chemical Countermeasures Research Program (CCRP), managed respectively by ASPR/BARDA and NIH/NIAID, in collaboration with Battelle[1], have selected opaganib for evaluation as a potential medical countermeasure (MCM) against Sulfur Mustard exposure Opaganib, a novel oral small molecule, is the first sphingosine kinase-2 (SPHK2) inhibitor investigational drug targeting sphingolipid metabolism to be evaluated as a chemical countermeasure Selection for the therapeutic testing/screening program, following opaganib's previous acceptance into the Radiation and Nuclear Countermeasures Program (RNCP) for Acute Radiation Syndrome (ARS), provides the potential to see broad activity across both radiation and Sulfur Mustard injuries Opaganib has five-year shelf-life and is easy to administer and distribute for use against potential chemical weapon attack, if approved by the U.S. Food and Drug Administration (FDA) Opaganib is being developed for multiple additional indications, including COVID-19, acute respiratory distress syndrome (ARDS) and oncology TEL AVIV, Israel and RALEIGH, N.C., March 5, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, together with its partner Apogee Biotechnology Corporation, today announced that opaganib[2] has been selected by the U.S. government's Chemical Medical Countermeasures (Chem MCM) Program and Chemical Countermeasures Research Program (CCRP) for evaluation as a potential medical countermeasure (MCM) against inhalation Sulfur Mustard exposure. The overall evaluation will also include assessment of opaganib's efficacy against sub-chronic fibrosis and acute respiratory distress syndrome (ARDS) resulting from Sulfur Mustard exposure. The Chem MCM Program is administered by the Biomedical Advanced Research and Development Authority (BARDA), a component of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS), and the CCRP is managed by the National Institute of Allergy and Infectious Diseases (NIAID), part of the HHS National Institutes of Health (NIH). Sulfur Mustard is a powerful alkylating chemical warfare agent. Exposure to Sulfur Mustard causes extensive skin blistering and severe injury to the eyes, lungs, and multiple organs, causing potentially fatal damage. Primarily affecting the lungs, Sulfur Mustard poisoning can result in symptoms such as acute lung injury, acute respiratory distress syndrome, bronchiolitis obliterans, fibrosis, and subsequent associated infections. "With the alarming increase in global geo-political instability, the opportunity to evaluate opaganib as a potential vital protective agent against chemical attack is inspiring. We, and our development partner, Apogee Biotechnology Corporation, are delighted to partner with the NIH/NIAID, ASPR/BARDA, and Battelle in our efforts to make a significant difference in this area of huge medical and societal need," said Dror Ben-Asher, RedHill's Chief Executive Officer. "Opaganib is the first selective sphingosine kinase-2 (SPHK2) inhibitor investigational drug targeting sphingolipid metabolism to be evaluated as a chemical countermeasure. Its selection for the U.S. government's Chemical Countermeasures Research Program, following opaganib's previous acceptance into the U.S government's Radiation and Nuclear Countermeasures Program for Acute Radiation Syndrome (ARS), provides the potential to see broad activity across both radiation and Sulfur Mustard injuries." Opaganib, a novel oral, small molecule pill with a five-year shelf-life, is easy to administer and distribute for use against potential chemical weapon attack, if approved by the FDA. About Opaganib (ABC294640) Opaganib, a proprietary investigational host-directed and potentially broad-acting drug, is a first-in-class, orally administered sphingosine kinase-2 (SPHK2) selective inhibitor with anticancer, anti-inflammatory and antiviral activity, targeting multiple potential diseases, including gastrointestinal acute radiation syndrome (GI-ARS), COVID-19, other viruses as part of pandemic preparedness, and cholangiocarcinoma (bile duct cancer). Opaganib's host-directed action is thought to work through the inhibition of multiple pathways, the induction of autophagy and apoptosis, and disruption of viral replication, through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SPHK2, DES1 and GCS). Opaganib was selected by the U.S. government's Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases, part of the HHS National Institutes of Health, for the nuclear medical countermeasures product development pipeline as a potential treatment for Acute Radiation Syndrome (ARS). Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc., Nasdaq: GILD), significantly improving potency while maintaining cell viability, in a U.S. Army-funded and conducted in vitro Ebola virus study. Being host-targeted, and based on data accumulated to date, opaganib is expected to maintain effect against emerging viral variants. In prespecified analyses of Phase 2/3 clinical data in hospitalized patients with moderate to severe COVID-19, oral opaganib demonstrated improved viral RNA clearance, faster time to recovery and significant mortality reduction in key patient subpopulations versus placebo on top of standard of care. Opaganib has demonstrated its safety and tolerability profile in more than 470 people in multiple clinical studies and expanded access use. Data from the opaganib global Phase 2/3 study was published in medRxiv. Opaganib has received Orphan Drug designation from the FDA for the treatment of cholangiocarcinoma and has undergone studies in advanced cholangiocarcinoma (Phase 2a) and prostate cancer. Opaganib also has a Phase 1 chemoradiotherapy study protocol ready for FDA-IND submission. Opaganib has also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.
