Study Description
Brief Summary
The purpose of this study is to demonstrate the safety of Umbilical Cord Tissue Derived Mesenchymal Stem Cells (UCMSCs) administered intravenously in patients with acute pulmonary inflammation due to COVID-19 with moderately severe symptoms

Outcome Measures
Primary Outcome Measures
- Percent of participants with treatment related Serious Adverse Events (SAE) [12 months]
Safety of UCMSCs will be reported as the percentage of participants in each treatment group that experienced a treatment related SAEs.
Secondary Outcome Measures
- Change in inflammatory marker levels [Baseline, Day 30]
Change in serum inflammatory marker levels including Interleukin (IL) IL-6, IL-2, Tumor Necrosis Factor Alpha (TNF-a) and procalcitonin will be evaluated in ng/L.
- Change in systemic inflammatory marker levels [Baseline, Day 30]
Change in serum systemic inflammatory marker levels including D-dimer, high sensitivity C-reactive protein (hsCRP) and ferritin will be evaluated in mg/L.
- COVID-19 Viral Load [Up to 30 Days]
Assessed using blood samples or nose/throat swabs.
- Change in SOFA score [Baseline, Up to 30 Days]
Sequential Organ Failure Assessment (SOFA) will be used to assess organ failure including the cardiovascular system, coagulation system, liver, kidney and other extra-pulmonary organs. SOFA score ranges from 0-24 with the higher score indicating worse outcomes.
- Change in electrolytes levels [Baseline, Up to 30 Days]
Sodium, Potassium, Chloride and Carbon Dioxide (CO2) will be evaluated in mmol/L. Changes from baseline to Day 30 will be compared between groups.
- Change in LDH levels [Baseline, Up to 30 Days]
Serum Lactate Dehydrogenase (LDH) levels assessed in U/L. Changes in LDH from baseline to Day 30 will be compared between groups.
- Number of subjects discharged from the ICU [Up to 7 Days]
ICU monitoring status will be reported as the number of subjects discharged from the ICU within 7 days.
- Percentage of participants with less requirement for vasoactive agents [Up to 30 Days]
Percentage of participants requiring less use of vasoactive agents will be reported.
- Rate of Mortality [Up to 30 Days]
Percentage of participant deaths throughout the study period.
- Percentage of participants with changes in immune marker expression [Up to 30 Days]
The percentage of participants with changes in serum immune marker levels including Cluster of Differentiation (CD) CD 4+ and CD 8+, as evaluated by treating physician will be reported.
- Percentage of participants with changes in radiologic findings [Up to 30 Days]
Percentage of participants with changes in their chest imaging such as ground-glass opacity, local patch shadowing, bilateral patch shadowing and interstitial abnormalities will be reported. Imaging will be assessed by treating physician using chest radiography or chest Computed Tomography (CT).
- Percentage of participants with less pneumonia symptoms [Up to 30 Days]
Percentage of participants showing less pneumonia symptoms will be reported as evaluated by treating physician using chest radiography or chest CT.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Provide written informed consent
-
Male or female subjects age > 18 years at the time of signing the Informed Consent Form.

-
Moderate:
-
Patients with moderate disease are symptomatic (e.g. fever, cough, headache, myalgia, sore throat, nasal congestion, nausea, vomiting, diarrhea, fatigue, anosmia, or dysgeusia) and have abnormal chest imaging or some degree of hypoxia requiring supplemental oxygen but not intubation.
-
Moderate-severe:
-
The Moderately Severe disease category includes patients who are symptomatic (as described above), have abnormal chest imaging, but also have worsening hypoxia compatible with mild acute respiratory distress syndrome (ARDS) (Partial Pressure of Oxygen (PaO2)/Fraction of Inspired Oxygen (FiO2) </= 300 but > 200) - Berlin criteria; but do not yet require intubation .
-
Adequate venous access
-
For female patients only, willingness to use FDA-recommended birth control until 6 months post treatment.

Exclusion Criteria:
-
PaO2/FiO2 </= 200

-
Advanced cardiac (eg, severe heart failure [New York Heart Association (NYHA) III-IV]) or pulmonary diseases;
-
