TEL AVIV, Israel and RALEIGH, NC, July 31, 2023, RedHill Biopharma Ltd. (Nasdaq: RDHL)
(“RedHill” or the “Company”), a specialty biopharmaceutical company, today announced that RHB-107 (upamostat)3 has been accepted for inclusion in the Austere environments Consortium for Enhanced Sepsis Outcomes’ (ACESO) U.S.
Government-supported PROTECT multinational platform trial for early COVID-19 outpatient treatment to be conducted in the U.S., Thailand, Ivory Coast and South Africa. The Company also announced that the Phase 2 study, predominantly funded by
the U.S. Government Department of Defense's Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND), has received FDA clearance to start and is estimated to be completed by end of 2024.
Expected to begin enrolling patients in Q3 2023, the 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.
Selection of investigational products for inclusion in the study was based on review of the preclinical and early clinical data, evaluating, safety, tolerability, and efficacy of
the IP. Selection is also based on route of administration and product availability. Products with oral, subcutaneous, and intramuscular delivery modes have been prioritized due to acceptability and feasibility of administration.
“Having RHB-107 accepted for inclusion in the PROTECT platform study, following an extensive review of the potential value it can bring, by both the scientific and governmental
bodies involved in the study offers us a chance to further verify the promising efficacy results, including 100% reduction in hospitalization due to COVID-19, that we delivered in 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, broad-acting, host-directed antiviral that is expected to act independently of viral spike protein mutations and, if approved, would add to
treatment options such as Paxlovid (a multi-billion-dollar product), in the early COVID-19 treatment paradigm. RHB-107’s development runs alongside RedHill’s other U.S. Government-funded program with opaganib, a novel oral drug being developed in
collaboration with the National Institutes of Health Radiation and Nuclear Countermeasures Program for Acute Radiation Syndrome.”
Data from RHB-107’s 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 approx. 88% reduction in reported new severe COVID-19 symptoms after treatment initiation, with only 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 from severe COVID-19 symptoms with a
median of 3 days to recovery with upamostat compared to 8 days with placebo.
Discussions for external non-dilutive funding for RHB-107 Phase 3 COVID-19 development, in addition to the platform study, are advancing. Several collaborative projects for
pandemic preparedness testing RHB-107, with government and non-government bodies, in a range of preclinical studies against other viral targets are ongoing and under discussion with government and non-government bodies.

About RHB-107 (upamostat)
RHB-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.
In 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.
RedHill acquired the exclusive worldwide rights to RHB-107, excluding China, Hong Kong, Taiwan and Macao, from Germany's Heidelberg Pharmaceuticals (FSE: HPHA) (formerly WILEX
AG) for all indications.
