RHB-107 (upamostat) [11] – COVID-19, variants and other viruses
With an urgent need to develop broad-spectrum, host-directed antivirals for pandemic preparedness, RedHill is: - Currently in late-stage discussions regarding funding for a pivotal Phase 3 study for RHB-107 and close to finalizing inclusion in a key platform study - Working on several cooperative projects, with government and non-government bodies, on a range of preclinical studies with opaganib and RHB-107 (upamostat) against multiple viral targets, including influenza and Ebola (amongst others) Both once-daily RHB-107 (upamostat) and twice-daily opaganib demonstrated in vitro inhibition of Omicron BA.5 sub-variant in testing conducted by the University of Tennessee in October 2022 The United States Patent and Trademark Office (USPTO), in October 2022, granted a new method of use patent for opaganib for the inhibition of a disease caused by a coronavirus in patients having pneumonia and receiving supplemental oxygen at a fraction of inspired oxygen (FiO2) up to and including 60% In July 2022, opaganib's suggested host-directed mechanism of action was published in the journal Drug Design, Development and Therapy, describing opaganib's multi-faceted potential to: inhibit multiple pathways, induce autophagy and apoptosis, and disrupt the viral RTC (replication-transcription complex) through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SK2, DES1 and GCS) |
