Arm Description

Patient: Intravenous infusion of single-dose of Mesenchymal stem cells (MSCs)

Intravenous infusion of single-dose of Ringer's lactate, albumin and heparin solution

Outcomes

Primary Outcome Measures

Safety of intravenously infused UCT-MSC suspension
The primary expected outcome is the safety and tolerability of using intravenously infused UTC-MSC suspension in patients with pneumonia caused by SARS-CoV-2. This outcome will be evaluated by recording adverse events that must be reported throughout the study period.

Secondary Outcome Measures

Pulmonary function test to evaluate the improvement of respiratory function
Evaluation of lung function.
Radiography to evaluate the improvement of respiratory function
Evaluation of pulmonary function using breathing chest radiography. Assessment of peripheral opacities, interstitial and airspace opacities, diffuse airspace opacities, interstitial opacities, lobar consolidation, atelectasis, cavities, pulmonary cysts, and emphysema.
6-minute walk to evaluate the improvement of respiratory function
Distance covered by the patient in a period of 6 minutes.
Decrease on days of non-invasive mechanical ventilation
Analysis of ventilatory parameters and arterial blood gas analysis.
Biochemical tests to evaluate the improvement of laboratory parameters
D-dimer, C-reactive protein, erythrocyte sedimentation rate, ferritin, creatine, urea, saline, potassium, bilirubin, total protein and fractions, albumin, globulin, oxalacetic transaminase, pyruvic transaminase, lactate dehydrogenase, creatine phosphokinase, troponin I, coagulogram.
Blood count to evaluate the improvement of laboratory parameters
Red blood cells, hemoglobin, hematocrit, total leukocytes, basophil, eosinophil, neutrophil, lymphocytes, monocytes, platelets.
Viral load to evaluate the improvement of laboratory parameters
Expression of the RpRd gene.
Cytokine dosage to evaluate inflammatory parameters
Granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin (IL) -2, IL-6, IL-7, IL-8, tumor necrosis factor (TNF) α, monocyte chemoattractant protein-1 (MCP1/CCL2) and macrophage inflammatory protein 1-alpha (MIP1a/CCL3).
Decrease in hospital stay
Evaluation of hospitalization days.
Computed tomography score to evaluate the improvement of pulmonary function
Chest computed tomography evaluation will analyze the following characteristics: ground glass opacities, linear opacities, consolidation, interlobular septal thickening, crazy-paving pattern, subpleural lines, bronchial wall thickening, lymph node enlargement and pleural effusion. Lesions will quantify by assigning a score to all abnormal areas involved. Each lobe will assigned a score of 0 (0% involvement), 1 (1-25% involvement), 2 (26-50% involvement), 3 (51-75% involvement) or 4 (76%-100% involvement). The total score will be the sum of all lobes, ranging from 0 to 25.
Reduction in the percentage of intubated patients
Clinical evaluation of patients.
Decrease in mortality
Evaluation of the number of patients who died during the study.

5. Study Description

Brief Summary
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.
Detailed Description
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.
