The U.S. Environmental Protection Agency (EPA) identified 123 sites in the United States that could potentially expose millions of people to phosgene due to plant malfunction or bioterrorism[1]\nPhosgene inhalation can be extremely dangerous, causing significant, even fatal, respiratory injury. No known approved antidote or reversal agent currently exists, and, if approved, opaganib may provide potential for stockpiling for emergency use in the event of a major public safety incident\nWith multiple U.S. government collaborations for chemical and medical countermeasures and pandemic preparedness, RedHill's opaganib is a novel, host-directed, potentially broad acting, orally administered small molecule, clinical-stage drug with demonstrated safety & efficacy profiles, being developed for various oncology, viral infections, inflammatory diseases and chemical and nuclear/radioprotection indications\nTEL AVIV, Israel and RALEIGH, N.C., Oct. 22, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (\"RedHill\" or the \"Company\"), a specialty biopharmaceutical company, today announced the signing of a collaborative research agreement with Duke University School of Medicine outlining plans for multiple in vivo studies. The program is designed to test opaganib[2] as a potential medical countermeasure to treat phosgene inhalation injury, aimed at providing results sufficient to advance opaganib into further definitive U.S. government-sponsored development under the U.S. Food and Drug Administration's (FDA) Animal Rule pathway to approval. The FDA Animal Rule allows for the use of pivotal animal model efficacy studies to support FDA approval of new drugs when human clinical trials are not ethical or feasible. Under this research agreement, RedHill will provide required drug quantities for animal studies, analytical support to quantify drug concentrations in plasma samples, and share dosing regimen with the Achanta Lab at Duke University.\n\n\n\n\"Opaganib is currently being tested, by various governmental research bodies, in multiple areas that urgently require new chemical and medical countermeasure therapeutic options,\" said Dr. Satya Achanta, D.V.M., Ph.D., Assistant Professor in the Department of Anesthesiology at Duke University School of Medicine. \"Our research will help determine whether there is a potential protective role of opaganib in limiting damage caused by phosgene inhalation.\"\n\"Notably used as a chemical weapon during World War I, phosgene, a toxic, colorless chemical, is today widely used in industrial processes for the manufacture of plastics and pesticides. The U.S. Environmental Protection Agency (EPA) identified 123 sites in the United States that could expose millions of people to phosgene potentially due to plant malfunction or bioterrorism,\" said Gilead Raday, RedHill's Chief Operating Officer and Head of Research and Development. \"This exciting collaboration with Duke University School of Medicine could pave the way to a potential therapy for the acute respiratory distress syndrome (ARDS) phosgene inhalation can cause, which can be extremely dangerous, causing significant, even fatal, injury. No known approved antidote or reversal agent currently exists, and, if approved, opaganib may provide potential for stockpiling for emergency use in the event of a major public safety incident.\"\nWhat is Phosgene inhalation injury\nPhosgene inhalation injury occurs when someone breathes in phosgene gas (COCl₂), a toxic chemical primarily used in industrial processes. Phosgene has a distinct odor, similar to freshly mown grass or hay. However, only 10% of the population may detect this odor at lower concentrations. The combination of its unassuming odor and poor human detection makes phosgene particularly dangerous. At higher concentrations, it is extremely dangerous, even fatal, and is a cause of acute respiratory distress syndrome (ARDS). It is believed that no antidotes or reversal agents exist at this time. Phosgene was notably used as a chemical weapon during World War I.\nToday, phosgene use in industry is ubiquitous - being used in the production of polymers, plastics and pesticides. Global estimates indicate that more than 12 million metric tons are produced annually[3]. Despite its widespread use, some regions poorly regulate its production, and concern exists for its potential as a weapon of bioterrorism. Given its severe toxicity and high mortality, research is primarily limited to an Animal Rule pathway to approval, which allows for the use of pivotal animal model efficacy studies to support FDA approval of new drugs when human clinical trials are not ethical or feasible.\nThe EPA identified 123 sites in the United States that could expose millions of people to phosgene if the plant malfunctions or becomes a target of bioterrorism.\nAbout Opaganib (ABC294640) \nOpaganib, 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.\nOpaganib'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).\nSeveral U.S. government countermeasures and pandemic preparedness programs have selected opaganib for evaluation for multiple indications, including Acute Radiation Syndrome (ARS), Ebola virus disease and others Funding bodies include the Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. government Department of Health & Human Services' National Institutes of Health and the Administration for Strategic Preparedness and Response's (ASPR) Center for Biomedical Advanced Research and Development Authority (BARDA).\nOpaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A and Ebola. 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 Ebola virus study, making it the first host-directed molecule to show activity in Ebola virus disease. 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 Ebola virus study.\nBeing 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.\nOpaganib 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.\nOpaganib has also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.\nAbout RedHill Biopharma  \nRedHill Biopharma Ltd.
