Eligibility
Inclusion criteria
Inclusion criteria: Adult patients suffering from SARS-CoV-2 induced severe pneumonia admitted to semi-intensive or intensive COVID Units because of the need of ventilation support. • Sign of the informed consent, • Patients of either sex, aged 18-80 years (inclusive), • Patient with a confirmed virological diagnosis of SARS-CoV2 infection by means of real-time Polymerase Chain Reaction, • Hospitalization due to clinical and radiological diagnosis of pneumonia, • PaO2/FiO2 value between 150-300 with impending necessity of noninvasive positive pressure respiratory support (nCPAP) or ventilator support through nasal pressure support ventilation (nPSV), • Systolic artery pressure >90 mmHg without amine support, • Modified Early Warning Score (MEWS) score =65 years) yes F.1.3.1 Number of subjects for this age range 40

| Measure | Time frame |
|---|---|
| Main Objective: Evaluation of the feasibility and safety of the use of allogeneic Mesenchymal stromal cells (MSC) to treat SARS-CoV-2 related severe pneumonia through the capability to treat all enrolled patients and monitoring the rate of adverse events;Secondary Objective: Evaluation of the efficacy of MSC in terms of: mortality rate trend of the daily PaO2/FiO2 ratio evaluation of the days to intubation date of independence from non-invasive mechanical ventilation date of independence from oxygen therapy hospitalization lenght radiological pattern response Evaluation of: neutrophil, lymphocyte and platelet counts, platelet mean volume, C-reactive protein, ferritin, procalcitonin, LDH, fibrinogen, and D-dimer. Comparative immunological study of the cytokine pattern and the immunophenotyphic cell profile of bronchoalveolar lavage fluid and peripheral blood samples will be carried out in order to establish the pathogenic mechanisms of COVID-19 tissue injury and the mechanism of action of MSC in this specific clinical setting. Establish which IMP used, as stratified according to the tissue origin, is associated with the best result in terms of safety and efficacy.;Primary end point(s): The feasibility will be assessed through the evaluation of the production capacity of each Cell Factory participating in the study in terms of an adequate amount of cellular product lots sufficient to treat 100% of the patients recruited. In addition, the process of transfer of the cellular product to the Clinical Unit will be validated, so that all the quality, safety and therapeutic properties will be guaranteed, with particular reference to its viability. Finally, a protocol for the bedside preparation of the final suspension for administration will be implemented according to the Good Clinical Practice. The safety will be assessed by recording all adverse events as coded by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, based on their duration, intens | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The efficacy will be assessed through the evaluation of a) mortality rate (%) at 2 and 4 weeks from the end of the treatmentfollow-up, b) percentage of change of the daily PaO2/FiO2 ratio in comparison with the basal value, c) percentage of patients under invasive mechanical ventilation, d) days under non-invasive mechanical ventilation, e) days under oxygen therapy, f) radiological response, g) days of hospitalization, h) percentage change of the radiologic score with respect to the basal value; Change of the following laboratory values after 2 and 4 weeks from the end of the MSC treatment of follow-up in comparison to the basal values and expressed as percentages: neutrophil, lymphocyte and platelet counts, platelet mean volume, C-reactive protein, ferritin, procalcitonin, LDH, fibrinogen, and D-dimer.; Modification of the cytokine pattern and of the immunophenotyphic cell profile on both BALF and peripheral blood samples as assessed by means of ELISA, flow cytometry and single cell RNAseq before and after 1 and 2 weeks from the end of MSC treatment follow-up will be carried outevaluated.; We have planned to treat a group of 10 cases with umbilical cord MSCs, a group of 10 cases with umbilical cord blood MSCs, a group of 10 cases with bone marrow MSCs, and a group of 10 cases with adipose tissue MSCs. The percentages of total adverse events, SUSARs, and SARs related to the MSC treatment, together with the efficacy parameters will be compared among the groups.;Timepoint(s) of evaluation of this end point: Endpoints will be assessed at 4 hours, 48 ¿¿hours, 7, 14, and 28 days from the end of treatment or enrollment, as appropriate; End points will be assessed after 2 and 4 weeks from the end of the MSC treatment; End points will be assessed after 1 and 2 weeks from the end of the MSC treatment; End points will be assessed at 4 hours, 48 ¿¿hours, 7, 14, 28 and 180 days from the end of treatment or enrollment | — |
