TEL-AVIV, Israel and RALEIGH, N.C., Oct. 28, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced that the Company has been selected to further elaborate on opaganib's^[1] potential in a presentation to U.S. government representatives at the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense's (JPEO-CBRND) "Host Directed Therapeutics Industry Day". The meeting is scheduled to take place October 29-30, 2024, at the United States Patent and Trademark Office in Alexandria, VA.

The JPEO-CBRND manages U.S. government investments in chemical, biological, radiological, and nuclear (CBRN) defense equipment and medical countermeasures (MCMs). The JPEO-CBRND mission is to provide integrated, layered, chemical, biological, radiological, and nuclear defense capabilities to the Joint Force across combined Joint all-domain operations. Based on reviews, feedback, and discussion, the judges selected for presentation those therapeutics that demonstrated capability in the prophylaxis, post-exposure prophylaxis, and treatment of exposure to viruses, bacteria and toxins.

"Opaganib is already the subject of multiple ongoing collaborations with several U.S. government agencies. However, selection for presentation at this important governmental investment event provides a significant opportunity to highlight the growing body of evidence in support of opaganib's potential as an oral, host-directed, broad-acting viral, chemical and nuclear countermeasure," said Guy Goldberg, RedHill's Chief Business Officer.

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).

Several 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).

Opaganib 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.

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.
