Final analysis from the phase 3 MOVe-OUT trial showed that treatment with the investigational oral antiviral molnupiravir reduced the risk of hospitalization or death by 30% in at-risk patients with mild to moderate COVID-19.
Molnupiravir is an orally administered form of a ribonucleoside analogue that inhibits the replication of SARS-CoV-2. The updated trial analysis (ClinicalTrials.gov Identifier: NCT04575597) included 1433 adults with mild to moderate COVID-19 with symptom onset within 5 days of randomization. Patients were required to have at least 1 risk factor associated with poor disease outcomes.
Results showed that 6.8% (n=48/709) of patients treated with molnupiravir were either hospitalized or died through day 29 following randomization compared with 9.7% (n=68/699) of patients treated with placebo (absolute risk reduction, 3.0%; 95% CI, 0.1-5.9; nominal P =.0218), corresponding to a relative risk reduction of 30% (relative risk, 0.70; 95% CI, 0.49-0.99). There was 1 death reported in the molnupiravir arm and 9 deaths in the placebo arm.
The safety profile of molnupiravir was consistent with that previously reported at the planned interim analysis.
Merck and Ridgeback Biotherapeutics submitted a request for Emergency Use Authorization for molnupiravir in October 2021 based on efficacy results from the planned interim analysis of the MOVe-OUT trial. Findings of this interim analysis, which included data from 775 adults, showed that molnupiravir reduced the risk of hospitalization or death by approximately 50%.
The Food and Drug Administration (FDA)’s Antimicrobial Drugs Advisory Committee will be reviewing all available data for molnupiravir on November 30, 2021.
