COVID-19 is a respiratory disease caused by the new coronavirus (SARS-CoV-2) and causes considerable morbidity and mortality.
Currently, there is no vaccine or therapeutic agent to prevent and treat a SARS-CoV-2 infection. This clinical trial is designed to evaluate the use of Tocilizumab in combination with hydroxychloroquine and azithromycin for the treatment of hospitalized adult patients with COVID-19.
