Remdesivir is a broad-spectrum antiviral drug having in vitro activity against severe acute respiratory syndrome coronavirus 2 and is currently being used on a compassionate basis outside of clinical trials.
To analyze the efficacy and safety of remdesivir compared with other interventions in coronavirus disease 2019 (COVID-19) patients.
We searched online databases to include randomized controlled trials evaluating the efficacy and safety of remdesivir compared with other interventions in COVID-19 patients. We summarized efficacy and safety data as risk ratios (RRs) with 95% confidence interval (CI) and used Mantel-Haenszel fixed or random-effect models. We estimated the number needed to treat (NNT) to cause one additional outcome. We used the GRADE approach to assess the quality of the evidence for all outcome parameters.
We included four randomized controlled trials. We observed no significant difference in mortality (RR: 0.83; 95%CI: 0.57–1.20; I2 = 59%) and rate of ventilation (RR: 0.69; 95%CI: 0.41-1.18; I2 = 77%) between remdesivir- and placebo-treated patients. Remdesivir showed higher rates of clinical recovery than placebo (RR: 1.10; 95%CI: 1.04–1.16; I2 = 0%; NNT: 14.3). We observed no difference in overall adverse events between remdesivir- and placebo-treated patients (RR: 1.05; 95%CI: 0.86–1.27; I2 = 77%). We observed less risk of serious adverse events (RR: 0.75; 95%CI: 0.63–0.89; I2 = 0%) in remdesivir- than placebo-treated patients. The GRADE approach suggested moderate quality of evidence for all efficacy and safety outcomes.
We observed limited clinical benefit of remdesivir over placebo in the treatment of COVID-19. Our findings could be biased because of the small number of trials.
Core Tip: Remdesivir is an antiviral drug having in vitro and in vivo activity against severe acute respiratory syndrome coronavirus 2. United States Food and Drug Administration has granted emergency use authorization for its use in all hospitalized patients. The findings of this meta-analysis suggest remdesivir can enhance clinical recovery without having significant benefits on mortality outcomes. because of lack of any major safety concerns, its use is recommended in the absence of effective antiviral drugs against coronavirus disease 2019.
