Study design details

Main study objective

To assess the effectiveness and safety of tocilizumab in the treatment of interstitial pneumonia due to COVID19 with severe respiratory failure treated at the hospitalization ward to prevent the need for mechanical ventilation and ICU admission.

Outcomes

% of patients with an event on day 15. Event is defined as: admission to the ICU by COVID-19 or death after admission by COVID-19. % of patients with an event on the day on days 1, 3, 7 and 29. Time to event Mortality on day 15 and 29 % of patients in need of oxygen therapy in each of its modalities Hospitalization time Change in the analytical levels % of patients with SAEs

Data analysis plan

490/5000 The incidence in exposed (cohort treated with tocilizumab) and in non-exposed (untreated cohort) will be calculated for each of the effectiveness variables. From these, the measures of association relative risk (RR), absolute risk reduction (RAR) and relative risk reduction (RRR) will be calculated for each of the variables, with their 95% CIs. Additionally, the odds ratios (OR) will be calculated. The RR adjusted for comorbidities and prognostic factors will be estimated.
