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 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. "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'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 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 also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.
