COVID-19
Ongoing global Phase 2/3 study
Opaganib’s unique mechanism of action combines potent antiviral and anti-inflammatory activities. Opaganib is host-targeted and is expected to be effective against emerging viral variants, having already demonstrated strong inhibition against variants of concern, including Delta.
Opaganib was studied in a global Phase 2/3 study in hospitalized patients with severe COVID-19 pneumonia (NCT04467840). Opaganib previously delivered positive U.S. Phase 2 data in patients with moderate to severe COVID-19. RedHill is pursuing the development program for opaganib and is in ongoing discussions with multiple regulatory agencies regarding potential pathways to approval.
