A retrospective, observational study published in Lancet Rheumatology has shown that tocilizumab (TCZ) may reduce the risk of death or the need for mechanical ventilation in severe COVID-19 pneumonia. This observational study included adults, with severe COVID-19 pneumonia, who were hospitalized between Feb 21 and March 24, 2020. All were on the standard of care (ie, supplemental oxygen, hydroxychloroquine, azithromycin, antiretrovirals, and low molecular weight heparin), and a non-randomly selected subset of patients also received TCZ.
