Forty patients with COVID-19 will receive an intravenous infusion of one dose of 1.000.000 umbilical cord mesenchymal cells per kilo of the patient. Twenty patients will receive a placebo (Ringer's lactate solution, albumin and heparin). Conventional treatment will be performed together with the infusion of cells, during the study period. The evaluation times will be at pre-infusion, 6 and 24 hours, days 5 and 28, 3 and 6 months. The patient exams performed: serology, biochemistry, blood count and blood gas analysis, metabolomics/proteomics, antibody evaluation, electrocardiogram, CT-scan and X-ray, cytokines, viral load, cytometry, and clinical evaluation. The patients will be evaluated all the time, during hospitalization period, to assess adverse events.
The purpose of this study is evaluate the feasibility, safety and potential efficacy of an advanced cell therapy product for the treatment of patients with SARS-CoV-2 pneumonia.
