Abstract
AbstractThe efficacy of molnupiravir in treating patients with coronavirus disease 2019 (COVID‐19) has been inconsistent across randomized controlled trials (RCTs). Thus, this meta‐analysis was conducted to clarify the literature. A literature search of electronic databases—PubMed, Embase, and Cochrane Library—was performed to identify relevant articles published up to December 31, 2022. Only RCTs that investigated the clinical efficacy and safety of molnupiravir for patients with COVID‐19 were included. The primary outcome was all‐cause mortality at 28–30 days. This pooled analysis of nine RCTs did not reveal a significant difference in all‐cause mortality between molnupiravir and control groups (risk ratio [RR], 0.43; 95% confidence interval [CI], 0.10–1.77) for overall patients. However, the risks of mortality and hospitalization were lower in the molnupiravir group than in the control group (mortality: RR, 0.28; 95% CI, 0.10–0.79; hospitalization: RR, 0.67; 95% CI, 0.45–0.99) among nonhospitalized patients. In addition, molnupiravir use was associated with a borderline higher virological eradication rate relative to the control (RR, 1.05; 95% CI, 1.00–1.11). Finally, no significant difference in adverse event risk was discovered between the groups (RR, 0.98; 95% CI, 0.89–1.08). The findings reveal the clinical benefits of molnupiravir for nonhospitalized patients with COVID‐19. However, molnupiravir may not improve the clinical outcomes of hospitalized patients. These findings support the recommended use of molnupiravir for treating nonhospitalized patients with COVID‐19 but not for hospitalized patients.
