Official Title
Single Donor Banked Bone Marrow Mesenchymal Stromal Cells for the Treatment of COVID-19 Induced ARDS: A Non-Blinded Randomized, Controlled Study
Brief Summary

This is a study for patients who have respiratory infection caused by SARS-CoV-2 that have not gotten better. Because there is no standard treatment for this infection, patients are being asked to volunteer for a gene transfer research study using mesenchymal stem cells (MSCs). Stem cells are cells that do not yet have a specific function in the body. Mesenchymal stem cells (MSCs) are a type of stem cell that can be grown from bone marrow (the spongy tissue inside of bones). Stem cells can develop into other types of more mature (specific) cells, such as blood and muscle cells. The purpose of this study is to see if MSCs versus controls can help to treat respiratory infections caused by SARS-CoV-2.

Detailed Description

Earlier, a healthy donor provided blood cells to generate MSCs. These cells were grown and

frozen for later use.



Before being treated, the patient will receive a series of standard medical tests:



- Physical exam and history



- SARS-CoV-2 test



- Blood tests



- Chest X-ray or chest CT Scan



- A urine pregnancy test, when applicable



The patient will be randomly assigned to a study group. We'll use a computer to put the

patient into study group A (study drug) or group B (control) by chance (randomized). Patients

randomized to the control group, will receive the standard treatment for their respiratory

infection.



These tests are done to assess the patient's eligibility to receive the cells. On the day

that the patient is scheduled to receive the cells they will be pre-medicated with Benadryl

and Tylenol. The patient will then receive a single intravenous (into the vein) infusion of 2

x 10^6 cells/kg of MSCs. The patient will be monitored closely for two hours after the

infusion.



The patient will receive standard medical tests when getting the infusion and afterwards. As

part of the research study, the patient will be evaluated daily for 7 days and then weekly at

weeks 2, 3, and 4. The evaluations that will be done at these visits include:



- Physical exam and history



- SARS-CoV-2 test



- Blood tests



- Chest X-ray or chest CT Scan

Eligibility Criteria

Inclusion Criteria:

1) 18 years or older 2) Confirmed SARS-CoV2 infection real-time reverse transcription
polymerase chain reaction (RT-PCR) assay 3) Moderate to severe acute respiratory distress
syndrome (ARDS), based on the degree of impairment of oxygenation as defined by the ratio
of arterial oxygen tension to fraction of inspired oxygen (PaO2/FiO2). Based on the Berlin
criteria noted below. 1. Moderate ARDS: PaO2/FiO2 100-200 mmHg, on invasive or noninvasive mechanical ventilation settings that include EEP ≥5 cm H2O 2. Severe ARDS: PaO2/FiO2 ≤100 mmHg on ventilator settings that include PEEP ≥5 cm H2O

AND - Bilateral opacities present on chest radiograph or computed tomographic (CT) scan, that are not fully explained by pleural effusions, lung collapse, or lung nodules. - Respiratory failure not fully explained by cardiac failure or fluid overload.

Exclusion Criteria: 1. Currently receiving extracorporeal membrane oxygenation (ECMO) 2. Severe chronic respiratory disease requiring use of home oxygen 3. Pregnant or lactating 4. Known hypersensitivity to dimethyl sulfoxide (DMSO) 5. Unstable hemodynamics (ventricular tachycardia or fibrillation) 6. Uncontrolled bacterial or fungal co-infection 7. Any end-stage organ disease or condition, which in the opinion of the Investigator, makes the patient an unsuitable candidate for treatment 8. Inability to obtain informed consent (from patient or legally appropriate proxy) 9. Presence of any contraindication to receiving prophylactic low dose unfractionated or low molecular weight heparin.
