Severe COVID-19 infection (finalized, proof of concept)
Resomelagon was also tested in the RESOVIR-1 study, a 60-patient placebo-controlled Phase 2A investigator initiated clinical trial of treatment of hospitalized COVID-19 infected patients who required supplemental oxygen. The study was a part of the RESOVIR (resolution in viral infection) collaboration, 100 mg resomelagon or placebo was administered orally once daily for 2 weeks.
All resomelagon treated patients (including the first 6 open-label safety patients) achieved respiratory recovery on average 4.0 days (40%) quicker than placebo treated patients (5.9 days and 9.9 days on average respectively). Resomelagon patients were discharged on average 3.3 days earlier than placebo and by day 4, 41% of resomelagon patients had been discharged vs 0% for placebo.
The results of the study and preclinical results, supporting the effect of resomelagon, have been published in British Journal of Pharmacology in December 2024 Pages 4750-4765 (DOI: 10.1111/bph.17322)

The clinical study has been followed by testing the compound in a preclinical model of COVID-19 infection as well as in an ex vivo study with human monocytes incubated with the virus with both studies supporting profound effect of the compound on COVID-19 induced hyperinflammation.
Currently the compound is tested in preclinical models as well as ex vivo settings using human monocytes incubated with highly clinically relevant viral. Data from these studies will be used to evaluate the continued clinical development of resomelagon as a novel treatment approach to modulate viral-induced hyperinflammation for the benefit of the patients.
