Remdesivir is one of few FDA-approved treatments for severe cases of Coronavirus Disease 2019 (COVID-19). To better assess its efficacy and safety, we conducted a meta-analysis to systematically identify and synthesize existing findings. We conducted a comprehensive literature search among six electronic databases and unpublished studies. Random-effects meta-analyses were performed to summarize the risk ratio (RR) and rate estimates from eligible studies. Funnel plots, the Egger test, and the trim and fill analysis were used to detect publication bias. Thirteen eligible studies were included in this meta-analysis, giving a pooled sample size of 10,002 COVID-19 hospitalized patients (5068 administered remdesivir; 4934 control). Among patients on remdesivir, we synthesized mortality (15%, 95% confidence interval [CI]: 9%, 22%), clinical improvement (64%, 95% CI: 51%, 78%), recovery (70%, 95% CI: 57%, 83%), hospital discharge (74%, 95% CI: 60%, 87%), serious adverse effect (SAE) (21%, 95% CI:13%, 29%), and Grade 3 or 4 adverse effect (AE) (30%, 95% CI: 12%, 48%). Patients on remdesivir were 17% (RR: 0.83, 95% CI: 0.65, 1.06) less likely to die than those within the control group. Additionally, remdesivir had favorable outcomes in terms of clinical improvement, recovery, and hospital discharge. Lastly, non-mechanically ventilated patients had better overall clinical outcomes than mechanically ventilated patients. Remdesivir shows a moderate-favorable treatment efficacy among hospitalized COVID-19 patients with disproportionate impact among non-mechanically ventilated patients; however, a substantial proportion of COVID-19 patients may suffer from SAE or Grade 3 or 4 AE during the treatment course.
