(Nasdaq: RDHL) (\"RedHill\" or the \"Company\"), a specialty biopharmaceutical company, today announced that the first patient has been enrolled in the Austere environments Consortium for Enhanced Sepsis Outcomes' (ACESO) U.S. government-supported PROTECT multinational platform trial for early COVID-19 outpatient treatment. RHB-107 (upamostat) is the first drug being tested in this platform study. Funded through non-dilutive external sources, including the U.S. Department of Defense, the PROTECT study is expected to be conducted in the U.S., Thailand, Ivory Coast, South Africa and Uganda, and is estimated to be completed by the end of 2024.\n\n\n\n\"Enrollment of the first patient in the study marks an important milestone for RHB-107 in the 300-patient U.S. government-supported PROTECT platform study, which could add significant validating data to the previous marked reduction in hospitalizations due to COVID-19 seen in the RHB-107 arm of our earlier U.S. Phase 2 study,\" said Gilead Raday, RedHill's Chief Operating Officer and Head of R&D. \"RHB-107 is a novel, potentially broad-acting, host-directed antiviral that is expected to act independently of viral spike protein mutations. If approved, RHB-107 could provide a much-needed additional option for use in the early COVID-19 treatment space, alongside Paxlovid. Additionally, with both RHB-107 and opaganib recently demonstrating distinct synergistic effect when combined individually with remdesivir in an in vitro Ebola study, we are making encouraging progress with our pipeline assets for pandemic preparedness.\"\nData from RHB-107's previous U.S. Phase 2 study showed a 100% reduction in hospitalization due to COVID-19, with zero patients (0/41) on the RHB-107 arms versus 15% (3/20) hospitalized for COVID-19 on the placebo-controlled arm (nominal p-value=0.0317). The study also showed an approximately 88% reduction in reported new severe COVID-19 symptoms after treatment initiation, with 2.4% of the RHB-107 treated group (1/41) versus 20% (4/20) of patients in the placebo-controlled arm (nominal p-value=0.036) reporting new severe COVID-19 symptoms. Further post-hoc analysis showed faster recovery periods from severe COVID-19 symptoms with a median of 3 days to recovery with upamostat compared to 8 days with the placebo.\nThe ACESO PROTECT study is an adaptive, randomized, double blind, multi-site Phase 2 platform trial, being conducted by researchers from ACESO and partner organizations, and administered by the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF). The study will compare investigational products (IPs) to control, in standard-risk, non-hospitalized adult SARS-CoV-2 infected participants with at least two moderate-severe symptoms at baseline. RHB-107 is the initial drug being evaluated in the early treatment arm of the study. The primary efficacy assessment in the early treatment indication will be time to sustained alleviation or resolution of COVID-19 symptoms. Participants will be followed for a period of up to 12 weeks.\nSelection of IPs for inclusion in the ACESO PROTECT study is based on review of the preclinical and early clinical data, evaluating safety, tolerability, and efficacy. Selection is also based on route of administration and product availability.\nRHB-107's development for COVID-19 runs parallel to the development of opaganib, RedHill's other novel oral drug, for Acute Radiation Syndrome, being done in collaboration with, and funded by, the U.S. government's National Institutes of Health Radiation and Nuclear Countermeasures Program. Both RHB-107 and opaganib also recently demonstrated distinct synergistic effect when combined individually with remdesivir, significantly improving potency while maintaining cell viability, in a U.S. Army-funded and conducted in vitro Ebola virus study.\nAbout RHB-107 (upamostat)\nRHB-107 is a proprietary, first-in-class, once-daily orally administered investigational antiviral, that targets human serine proteases involved in preparing the spike protein for viral entry into target cells. Because it is host-cell targeted, RHB-107 is expected to also be effective against emerging viral variants with mutations in the spike protein. RHB-107 is well tolerated; in the initial COVID-19 study, among 41 patients only one reported a drug-related adverse reaction (a mild, self-limited, rash).\nIn addition, RHB-107 inhibits several proteases targeting cancer and inflammatory gastrointestinal disease. RHB-107 has undergone several Phase 1 studies and two Phase 2 studies, demonstrating its clinical safety profile in approximately 200 patients[4].\nRedHill acquired the exclusive worldwide rights to RHB-107, excluding China, Hong Kong, Taiwan and Macao, from Germany's Heidelberg Pharma AG (FSE: HPHA) (formerly WILEX AG) for all indications.\nAbout HJF\nThe Henry M.
