Molnupiravir, an Oral Antiviral, Reduced the Risk of Hospitalization or Death in Patients with Mild-to-Moderate COVID-19

Molnupiravir, an investigational oral antiviral medicine, significantly reduced the risk of hospitalization or death by 50% in an interim analysis of the phase 3 MOVe-OUT trial. The planned analysis evaluated data from 775 at-risk, non-hospitalized adult patients with mild-to-moderate COVID-19. All patients enrolled had at least one risk factor associated with poor COVID-19 outcomes and were randomized within 5 days of symptom onset. At day 29, 7.3% of patients who received molnupiravir were either hospitalized or died, compared with 14.1% of placebo-treated patients (P= .0012). No deaths were reported in patients receiving molnupiravir, compared with 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). Discontinuation due to adverse events was lower with molnupiravir (1.3%) versus placebo (3.4%).
