SARS-CoV-2

Intervention(s):

Humanized monoclonal antibody Itolizumab: Treatment protocol for COVID-19 approved by MINSAP+ MAb Itolizumab. The patient will receive two doses of the MAb Itolizumab, 200 mg each, diluted to 200 mL of saline solution, separated by 72 hours, intravenously, with a slow infusion rate, not greater than 30 drops per minute, which means administer the product in approximately 2-3 hours.

Itolizumab

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Reduction of lung function decline (Rate of patients without the need to increase FiO2 to maintain stable SO2 and without the need for intubation and/or Rate of patients with decreased positive end-expiratory pressure (PPEP) values) . Measurement time: 7 days

Key secondary outcomes:

1. Oro-tracheal intubation rate (Rate of patients requiring intubation). Measurement time: 7 days. 2. Rate of non-invasive or invasive mechanical ventilation when respiratory failure occurs, or failure of non-invasive mechanical ventilation (Rate of patients requiring non-invasive mechanical ventilation (NIMV), Rate of patients requiring invasive mechanical ventilation, Rate of patients with NIMV failure). Measurement time: before, 48, 72, 120 and 168 hours after administering itolizumab 3. Duration time of mechanical ventilation or time until weaning (Time elapsed from the start date of mechanical ventilation to the date of weaning ). Measurement time: until withdrawal of mechanical ventilation 4. Rate of deceased patients (proportion of deceased patients out of the total number of patients included 14 days after being included or once discharged from hospital). Measurement time: 14 days after treatment. 5. Serum concentrations of IL1, IL6 and TNF alpha (reported in pg/ml according to the reference values of the commercial kits used). Measurement time: at the beginning, 48, 96 and 168 hours after itolizumab administration. 6. HSH Score (Temperature, visceromegaly, cytopenias, triglycerides, fibrinogen, ferritin, AAT (TGO). Measurement time: 48, 96 and 168 hours after itolizumab administration. 7. C-reactive protein, and absolute count of lymphocytes (positive or negative, qualitative variable) Measurement time: pre, 48 hours, 72, 120 and 168 8. Adverse events related to treatment (according to causality and intensity) Measurement time: pre before administration of the antibody, during and after while the patient is hospitalized 9. Hospitalization time (days in hospital from the date of receiving treatment with Itolizumab until discharge or death in hospital) Measurement time: At discharge or death
