Intervention(s):

Itolizumab (Experimental Group): Itolizumab + Plasmapheresis Itolizumab: A first dose of Itolizumab (humanized anti-CD6 monoclonal antibody) 1.6 mg / kg will be administered by intravenous route. In case the patient, because of its body weight (≥125 kg), requires more than 200 mg according to the proposed dose, only 200 mg will be administered. if the patient is no improvement in the symptoms and signs of the systemic inflammatory disease, the patient can receive additional doses of itolizumab up to a maximum of 4 doses, with intervals of 3 to 7 days after the preceding dose, for a maximum of 28 days. Plasmapheresis: It will be performed by intravenous route through the ulnar or lateral vein of the elbow flexure, with Cuff Pressure of 50mm Hg, using a Haemonetics or Nigale machine. It can be performed initially, concurrent with the administration of the first dose of Itolizumab; or the relevance of its use can be evaluated, 72 hours after the first dose of Itolizumab has been administered, taking into account the clinical status of the patient and the values of the laboratory parameters, especially the neutrophil / lymphocyte ratio (NLR). Plasmapheresis will be performed immediately before the administration of the corresponding Itolizumab dose. Up to a maximun of 4 plasmapheresis sessions can be performed.

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):

1- Recovery rate (The proportion of patients considered recovered will be calculated in relation to the total number of patients who received the therapeutic combination). Measurement time: At hospital discharge. 2- Rate of patients with disease progression (worsening in the classification of clinical status. According to the World Health Organization classification of Moderate, Severe, Critical (Stable, Unstable), any change in status during the evaluation period will be considered Progression). Measurement time: from the first plasmapheresis session at 0, 48h, 72h, 120h, 168h, 14 days, 21 days and 28 days or until hospital discharge or death of the patient.

Key secondary outcomes:

1- Intensive care stay time (Time elapsed from admission until discharge from the ICU). Measurement time: At ICU discharge 2- Hospital stay time (Time elapsed from hospital admission until to hospital discharge). Measurement time: At hospital discharge. Lung function: 3- Rate of patients without the need to increase FiO2 to keep SO2 stable (Proportion of patients in whom it is not necessary to increase FiO2). Measurement time: At hospital discharge. 4- Rate of patients who improve the PO2/FiO2 ratio (Rate of patients who increase the PO2/FiO2 ratio). Measurement time: At hospital discharge. 5- Rate of patients requiring non-invasive mechanical ventilation-NIMV (Rate of patients requiring non-invasive mechanical ventilation after starting treatment with the therapeutic combination). Measurement time: At hospital discharge. 6- Rate of patients requiring invasive mechanical ventilation (Rate of patients requiring invasive mechanical ventilation after starting treatment with the therapeutic combination). Measurement time: At hospital discharge. 7- Clinical Adverse Events-AE (From the total number of patients who will receive the therapeutic combination, the percentage that developed serious AE will be calculated, according to the CTCAE v5.0 classification. The type, duration, severity, result and causal relationship of the AE will be recorded). Measurement time: After each dose of therapeutic combination has been administered and during the entire hospitalization period and until hospital discharge. 8- Inflammation Markers (Evaluation of serum concentrations of IL6, Interferon gamma, TNF alpha and Neutrophil / lymphocyte ratio (NLR)). Measurement time: before each plasmapheresis session, immediately after plasmapheresis and 72 hours after plasmapheresis, and up to 72 hours after the last plasmapheresis. 9- Clinical laboratory tests (Evaluation of concentrations of Hemoglobin (Hb), Total leukocytes, Neutrophils, Lymphocytes, Platelets, Erythrosedimentation, C-reactive protein, Triglycerides, Ferritin, Creatinine, LDH (Lactate dehydrogenase), Amino-aspartate transferase, Pyruvic glutamic transferase, Fibrinogen, D-Dimer). Measurement time: before each plasmapheresis session, immediately after plasmapheresis and 72 hours after plasmapheresis, until discharge from hospital.

Important: These cases will be treated in a different room with the supervision of the intensivists. Each case will be evaluated individually (if the disease has been evolving for 8 days or more, treatment with Heberferon should be suspended, and prophylactic anticoagulant treatment should be indicated in cases that meet the criteria for said therapy). 5.
