BACKGROUND Since the outbreak of the COVID-19, numerous therapies to counteract severe disease have emerged. The benefits of Tocilizumab for severely infected COVID-19 patients and the methodologies of ongoing clinical trials are explored. METHODS A systematic search adhering to PRISMA guidelines was conducted in PubMed, Cochrane Central, medRxiv, and bioRxiv using the following keywords: \'Tocilizumab,\' \'Actemra,\' \'COVID-19.\' An additional sub-search was conducted on Clinicaltrials.gov to locate ongoing tocilizumab trials. RESULTS A total of 13 studies were included in the meta-analysis comprising 2120 patients. The treatment group had lower mortality compared to the control group (OR=0.42, 95% CI=0.26 to 0.69, P-value=0.0005, I2=55%). A descriptive analysis of 50 registered trials was conducted. CONCLUSION This review meta-analyzed the therapeutic benefits of tocilizumab in COVID-19 patients with severe disease for mortality, mechanical ventilation, and the characteristics of COVID-19 registered trials.
