Abstract: Background: Pneumonia is the most frequent and serious complication of COVID-19, due to an excessive and aberrant host immune response that is associated with an acute respiratory distress syndrome, with typical radiological findings and, in most critical patients, with a “cytokine storm”. IL-6 might play a key role in the cytokine storm induced bySARS-CoV-2 and interfering of IL-6 might be a potentially therapeutic strategy for severe and critical COVID-19. Tocilizumab is a recombinant humanized monoclonal antibody, directed against IL-6 receptor.

Methods: This multicentre study project includes a single-arm, single-stage, phase 2 study and a further parallel cohort, enrolling hospitalized patients with COVID-19 pneumonia and oxygen saturation at rest in ambient air ≤93% or requiring respiratory support. All the patients are treated with tocilizumab 8 mg/kg (up to a maximum of 800 mg) as one intravenous administration. A second administration (same dose) can be given after 12 hours if respiratory function has not recovered. Two-week and one-month lethality rates are the co-primary endpoints. The sample size planned for the phase 2 study is 330 patients. The parallel cohort will include patients who cannot enter the phase 2 study because being intubated from more than 24 hours, or having already received tocilizumab, or the phase 2 study has been closed due to reached sample size. Primary analysis will include patients enrolled in the phase 2 study. Results of the primary analysis will be validated in the prospective cohort of patients consecutively registered after phase 2 closure from March 20 to March 24, who were potentially eligible for the phase 2 study.
Discussion: This trial aims to verify the safety and efficacy of tocilizumab in the Italian population with COVID-19 pneumonia and respiratory impairment. Study design and conduct has been affected by the health emergency due to coronavirus pandemia in Italy in a time while the number of people who get infected or was hospitalized for respiratory impairment was dramatically increasing.
