Oral opaganib's reported potent in vitro activity against Omicron adds to previously observed inhibition of Delta and other SARS-CoV-2 variants of concern that cause COVID-19; Testing conducted by The University of Hong Kong School of Public Health, a world renowned WHO collaborating center
Based on the new and previously announced data, opaganib's unique human host-targeted, dual antiviral and anti-inflammatory suggested mechanism is expected to act independently of viral spike protein mutations and remain effective against Omicron sub-variants BA.2, XE and other emerging and future variants
Previously reported phase 2/3 clinical data showed reduced mortality in key subpopulations, improved viral RNA clearance, and faster time to recovery for moderate to severe hospitalized patients treated with opaganib
Regulatory submissions and discussions in the U.S., Europe, UK and additional countries are progressing regarding confirmatory data requirements and pathways to potential approval
TEL AVIV, ISRAEL and RALEIGH, NC / ACCESSWIRE / April 11, 2022 / RedHill Biopharma Ltd. (NASDAQ:RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced study results in which opaganib (ABC294640)[1], a leading oral drug candidate for hospitalized patients with moderate to severe COVID-19, was observed to have potent in vitro efficacy against the Omicron SARS-CoV-2 variant, while maintaining host cell viability. Based on the new and previously announced data, opaganib's unique human host-targeted, dual antiviral and anti-inflammatory suggested mechanism is expected to act independently of viral spike protein mutations and remain effective against Omicron sub-variants BA.2, XE and other emerging and future variants.

Work on testing opaganib against Omicron was conducted by the Centre for Immunology and Infection (C2i), The University of Hong Kong's world-renowned infectious diseases research center, School of Public Health, by Dr. Michael Chan, Principal Investigator, of the Centre for Immunology and Infection, who said: "The results of this study showed opaganib exerting potent inhibition of Omicron SARS-CoV-2 variant viral replication in a model that we believe comes as close as currently possible to representing the Omicron clinical pathophysiological pathway. These are highly promising results that lend further weight to opaganib's hypothesized host-mediated antiviral activity and expected effect irrespective of viral variant."
