Merck has officially 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.
Molnupiravir is being developed by Merck in collaboration with Ridgeback Biotherapeutics.
Last week, the companies released results from a planned interim analysis from a Phase 3 clinical trial, that 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 (28/385), compared with 14.1% of placebo-treated patients (53/377). Through Day 29, no deaths were reported in patients who received molnupiravir, as compared to 8 deaths in patients who received placebo.
Similarly, AstraZeneca submitted an EUA request to the FDA earlier this month for AZD7442, the company’s long-acting antibody combination for protection against symptomatic COVID-19.
In August 2021, AstraZeneca announced high-level results from the PROVENT pre-exposure prophylaxis trial which showed AZD7442 reduced the risk of developing symptomatic COVID-19 by 77%, compared to placebo. Importantly, the trial population included people with co-morbidities and who may be in need of additional protection from SARS-CoV-2 infection.
