The U.S. government's Biomedical Advanced Research and Development Authority (BARDA) selected opaganib for joint development & funding as a medical countermeasure (MCM) to treat Ebola virus disease (EBOV) -- The funding advances opaganib's positive development progress to date on the expected FDA Animal Rule pathway toward potential approval as an MCM for EBOV -- Recent U.S. Army-funded studies showed that opaganib delivered a statistically significant increase in survival in an in vivo EBOV model. The BARDA research and development contract provides initial funding for the collaboration, in pursuit of advancing opaganib to mitigate infection and contain EBOV outbreaks -- This year marks the 10th anniversary of the West Africa Ebola epidemic in which 11,000 people died, and there is still an urgent need for effective and useable therapies, with EBOV proving fatal in around half of all cases according to the World Health Organization (WHO)1 -- Opaganib, a novel potentially broad-acting drug, has shown mutation-resistant antiviral and anti-inflammatory activity, likely to directly impact vascular health - one of the main targets for EBOV dysfunction. It is believed to be the first host-directed molecule to show activity in EBOV in vivo and represents an alternative host-directed therapeutic strategy for biodefense and global health preparedness. Additional U.S. government collaborations with opaganib are ongoing -- Significant geopolitical and logistical challenges exist in managing outbreaks of disease and there is an urgent need for safe and effective, oral, small molecule therapeutics that can be stored and easily distributed and administered in an outbreak TEL-AVIV, Israel and RALEIGH, N.C., Oct. 14, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced that the U.S. government's Biomedical Advanced Research and Development Authority (BARDA), a center of the Department of Health and Human Services (HHS)' Administration for Strategic Preparedness and Response (ASPR), has selected opaganib2 for development to treat exposure to Ebola virus disease (EBOV). Under this cost-sharing contract, BARDA will provide partial funding for the company to further advance opaganib to mitigate infection and contain EBOV outbreaks. To date, opaganib has made positive development progress on the expected Animal Rule pathway towards potential approval as a treatment for EBOV. The Animal Rule allows for the use of pivotal animal model efficacy studies to support U.S. Food and Drug Administration (FDA) approval of new drugs when human clinical trials are not ethical or feasible. "EBOV is deadly, killing, on average, half of all those who contract it. This year marks 10 years since the West Africa Ebola epidemic in which 11,000 people died, and yet there are still no host-directed, small molecule therapies approved to provide effective and useable treatment strategies," said Guy Goldberg, RedHill's Chief Business Officer. "Currently only Inmazeb™, a combination of three monoclonal antibodies, and Ebanga™, a single monoclonal antibody, are FDA-approved to treat EBOV, as such there is an urgent medical need for additional effective and easy to distribute and administer EBOV therapies. There are also enormous geopolitical and logistical challenges to overcome in managing outbreaks such as EBOV, and others like Mpox, and so new host-directed, small molecule therapeutic options for biodefense and global health preparedness could prove to be major life-saving advances – this is especially true if they are capable of viral mutation-resistance, have extended shelf-lives for long-term storage, are relatively straightforward to transport to hard-to-reach territories, and are easy to administer without the need for cold-storage or injections." Opaganib delivered a statistically significant increase in survival time when given at 150 mg/kg twice a day (BID) in a United States Army Medical Research Institute of Infectious Diseases (USAMRIID) in vivo EBOV study, making it the first host-directed molecule to show activity in EBOV. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc.), significantly improving potency while maintaining cell viability, in a U.S. Army-funded and conducted in vitro EBOV study. Opaganib is currently also in development for multiple oncology, viral, inflammatory and diabetes and obesity-related indications, including COVID-19, acute respiratory distress syndrome (ARDS) and radiological and chemical protection or mitigation. This project is supported in whole or in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50124C00059. About Ebola virus disease: According to the Centers for Disease Control and Prevention (CDC), Ebola disease is a rare and often deadly illness, caused by infection by one of a group of four viruses, known as ebolaviruses. Transmission of the disease is mostly through contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with an ebolavirus. The course of the illness typically progresses from "dry" symptoms initially (such as fever, aches and pains, and fatigue), and then progresses to "wet" symptoms (such as diarrhea, vomiting and unexplained hemorrhaging, bleeding or bruising) as the person becomes sicker. Currently only Inmazeb™ (atoltivimab, maftivimab, and odesivimab-ebgn, Regeneron Pharmaceuticals, Inc.), a combination of three monoclonal antibodies and Ebanga™ (ansuvimab-zykl, Ridgeback Biotherapeutics, LP), a single monoclonal antibody, are FDA-approved to treat EBOV. Both are intravenously administered direct acting monoclonal antibody antivirals that bind to glycoproteins on the Ebola virus's surface to prevent the virus from entering a person's cells. There is an urgent need for host-directed small molecule therapies that may be effective against multiple strains of ebolavirus, less likely to be impacted by viral mutation, and that are easy to store, distribute and administer, especially in areas where healthcare services and infrastructures may be sub-optimal. 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 indications, including several cancers, diabetes and obesity-related disorders, gastrointestinal acute radiation syndrome (GI-ARS), Sulfur Mustard exposure, COVID-19, Ebola and other viruses as part of pandemic preparedness. 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 has been selected for evaluation by multiple NIH-funded U.S. government countermeasures programs: The Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the HHS National Institutes of Health, for the nuclear medical countermeasures (MCM) product development pipeline selected opaganib for development as a potential treatment for Acute Radiation Syndrome (ARS). Opaganib will also be evaluated as a potential countermeasure for inhalational Sulfur Mustard exposure under a joint screening core operated by the BARDA Chemical Medical Countermeasures (Chem MCM) Program and the NIH/NIAID Chemical Countermeasures Research Program (CCRP). Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A and Ebola. 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 Microorganisms. Opaganib has received several orphan-drug designations from the FDA in oncology and other diseases 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.

First new American College of Gastroenterology (ACG) Clinical Guideline[1] for H. pylori infection since Talicia's approval lists Talicia as an empirically prescribed first-line option Talicia's convenient all-in-one three times daily (TID) formulation offers a simplified patient experience, supporting high rates of eradication without needing prior resistance testing Talicia is the leading branded first-line therapy prescribed by U.S. gastroenterologists[2] for H. pylori infection, which affects approximately 35% of the U.S. adult population[3] Worldwide, around 66% of the population has H. pylori infection[4], which is classified by the World Health Organization (WHO) as a Group 1 carcinogen, being the strongest known risk factor for gastric cancer[5] and a major risk factor for peptic ulcer disease[6] RALEIGH, N.C. and TEL-AVIV, Israel, Sept. 9, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the placement of low-dose rifabutin-triple therapy, Talicia, as an empirically-prescribed first-line option for the treatment of Helicobacter pylori (H. pylori) infection in the newly published American College of Gastroenterology (ACG) Clinical Guideline: Treatment of H. pylori Infection, previously updated in 2017. "The ACG Clinical Guideline is clear that clarithromycin-based triple therapy is no longer a reliable first-line option for the treatment of H. pylori infection, unless prior resistance testing has shown clarithromycin susceptibility. Resistance rates to both of the antibiotics contained in Talicia, amoxicillin and rifabutin, are minimal - <3.0% and <1.0%, respectively[7] - supporting Talicia as a rational empirically-prescribed first-line option," Dr. Colin W. Howden, MD, Professor Emeritus, Chief of the Division of Gastroenterology, University of Tennessee Health Science Center. "Talicia's all-in-one formulation and flexible dosing schedule – three times daily (TID), at least four hours apart with food, for 14 days – offers a simplified patient experience, supporting high rates of eradication without the requirement of prior resistance testing." It has been almost eight years since the ACG Clinical Guideline's last update, which was prior to the launch of Talicia. "The newly updated ACG Clinical Guideline confirms the use of Talicia as a first-line option," said Rick D. Scruggs, President and Chief Commercial Officer of RedHill Biopharma, Inc. "Healthcare providers can be confident in their choice of Talicia without the requirement of prior resistance testing, and we trust that this newly updated ACG Clinical Guideline will continue to change the status quo of H. pylori treatment to further improve patient outcomes." About H. pylori H. pylori is a bacterial infection that affects approximately 35%[8] of the U.S. population, with an estimated two million patients treated annually3. Worldwide, around 66% 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 cancer[9] and a major risk factor for peptic ulcer disease[10] and gastric mucosa-associated lymphoid tissue (MALT) lymphoma[11]. More than 27,000 Americans are diagnosed with gastric cancer annually[12]. 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[13]. About Talicia® Talicia® is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address the high resistance of H. pylori bacteria seen with 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 by the ACG, FDA and the WHO in recent years. 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). In November 2019, Talicia® was approved by the U.S. FDA for the treatment of H. pylori infection in adults. 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 adherent[14] to their therapy had response rates of 90.3% in the Talicia® arm vs. 64.7% in the active comparator arm[15]. 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. TALICIA: INDICATION AND IMPORTANT SAFETY INFORMATION Talicia is a three-drug combination of omeprazole, a proton pump inhibitor, amoxicillin, a penicillin-class antibacterial, and rifabutin, a rifamycin antibacterial­­, indicated for the treatment of Helicobacter pylori infection in adults. 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. IMPORTANT SAFETY INFORMATION Talicia contains omeprazole, a proton pump inhibitor (PPI), amoxicillin, a penicillin-class antibacterial and rifabutin, a rifamycin antibacterial. It is contraindicated in patients with known hypersensitivity to any of these medications, any other components of the formulation, any other beta-lactams or any other rifamycin. Talicia is contraindicated in patients receiving rilpivirine-containing products. Talicia is contraindicated in patients receiving delavirdine or voriconazole. Serious and occasionally fatal hypersensitivity reactions have been reported with omeprazole, amoxicillin and rifabutin. Drug-induced enterocolitis syndrome (DIES) has been reported with use of amoxicillin, a component of Talicia. Severe cutaneous adverse reactions (SCAR) (e.g., Stevens-Johnson syndrome (SJS), Toxic epidermal necrolysis (TEN)) have been reported with rifabutin, amoxicillin, and omeprazole. Additionally, drug reaction with eosinophilia and systemic symptoms (DRESS) has been reported with rifabutin. Acute Tubulointerstitial Nephritis has been observed in patients taking PPIs and penicillins. Clostridioides difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range from mild diarrhea to fatal colitis. Talicia may cause fetal harm. Talicia is not recommended for use in pregnancy. Talicia may reduce the efficacy of hormonal contraceptives. An additional non-hormonal method of contraception is recommended when taking Talicia. Talicia should not be used in patients with hepatic impairment or severe renal impairment. Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs. These events have occurred as both new onset and exacerbation of existing autoimmune disease. The most common adverse reactions (≥1%) were diarrhea, headache, nausea, abdominal pain, chromaturia, rash, dyspepsia, oropharyngeal pain, vomiting, and vulvovaginal candidiasis.
