Opaganib

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.
