Merck announces submission of EUA application to the FDA for Molnupiravir, oral antiviral medicine, for the treatment of mild-to-moderate COVID-19
Merck, known as MSD outside the United States and Canada, and Ridgeback Biotherapeutics announced in a press release, that Merck has submitted an Emergency Use Authorization (EUA) application to the U.S. Food and Drug Administration (FDA) for molnupiravir, an investigational oral antiviral medicine, for the treatment of mild-to-moderate COVID-19 in adults who are at risk for progressing to severe COVID-19 and/or hospitalization.
The companies are actively working with regulatory agencies worldwide to submit applications for emergency use or marketing authorization in the coming months.
The submission is based on positive results from a planned interim analysis from the Phase 3 MOVe-OUT clinical trial, which evaluated molnupiravir in non-hospitalized adult patients with mild-to-moderate COVID-19 who were at risk for progressing to severe COVID-19 and/or hospitalization.
At the interim analysis, molnupiravir reduced the risk of hospitalization or death by approximately 50%; 7.3% of patients who received molnupiravir were either hospitalized or died through Day 29 following randomization, compared with 14.1% of placebo-treated patients. Through Day 29, no deaths were reported in patients who received molnupiravir, as compared to 8 deaths in patients who received placebo. The incidence of any adverse event was comparable in the molnupiravir and placebo groups (35% and 40%, respectively). The incidence of drug-related adverse events was also comparable (12% and 11%, respectively), and fewer subjects in the molnupiravir group discontinued therapy due to an adverse event compared to the placebo group (1.3% and 3.4%, respectively).
In anticipation of the results from MOVe-OUT and the potential for regulatory authorization or approval, Merck has been producing molnupiravir at risk and expects to produce 10 million courses of treatment by the end of 2021, with more courses expected to be produced in 2022.
