Plain English Summary
Background and study aims
Many acutely ill patients are killed by severe acute respiratory distress syndrome (ARDS) and septic shock complicated with multiple organ failure. ARDS is a condition where the lungs can't provide the body's vital organs with enough oxygen. The causes of ARDS include infection, severe shock, trauma, aspiration injury, or severe systemic inflammation. Septic shock is when blood pressure drops to a dangerously low level after an infection. Many people eventually die of loss of multiple organ function. Even with prompt and proper antibiotic treatment, the death rate is quite high. It is important to find a new method to improve survival rates. Stem cells are able to regulate the immune system, are anti-inflammation and have the ability to repair tissues. The aim of this study to test the safety of human umbilical cord-derived mesenchymal stem cells in patients with ARDS and multiple organ failure complicating severe septic shock.
Who can participate?
Patients aged 20-80 with ARDS or severe septic shock, whose symptoms do not improve 5 days after traditional or standard treatment
What does the study involve?
Participants are randomly allocated to be treated with one of three doses of stem cells administered into their veins. The injected number of stem cells is gradually increased if safety is confirmed after injection of the lower dose. Safety is defined as no relevant side effects, such as allergy, immunosuppressant effect, or treatment-associated organ damage or death. The stem cell treatment takes less than 2 hours. After discharge, participants are followed up regularly in the outpatient setting at 1 month and every 3 months. The total follow-up period is one year.
What are the possible benefits and risks of participating?
The possible benefits of stem cell treatment include life-supporting or life-saving effects. The treatment may be used in future to protect organ function in critically ill patients. The relevant risks are irregular heart rhythm, heart attack, heart failure, brain ischemia, bleeding, anemia, worsening kidney function, electrolyte imbalance, malignancy, and so on. However, the reported rate of the above side effects is less than 1%.

Acute respiratory distress syndrome and/or profound septic shock complicated with multiple organ failure
The eligible subjects who are willing to receive intravenous therapy with human umbilical cord-derived mesenchymal stem cells for ARDS and profound septic shock complicated with multiple organ failure will be enrolled into this study. Blood biochemistry study will be performed at baseline. Sequentially numbered opaque, sealed envelopes (SNOSE) will be used to allocate the study subjects. Three different dosages of human umbilical cord-derived mesenchymal stem cells will be administered intravenously:
1. 1.0 x 106 cells/kg (n=3)
2. 5.0 x 106 cells/kg (n=3)
3. 1.0 x 107 cells/kg (n=4)
The injected number of stem cells will be gradually titrated up if safety is confirmed after injection of the prior lower dose. The safety is defined as no relevant side effects after human umbilical cord-derived mesenchymal stem cell therapy, e.g., allergy, immunosuppressant effect, or therapy-associated organ damage or death. The duration of cell-based treatment with intravenous infusion of stem cells is less than 2 hours. After discharge, patients will be followed up regularly in the outpatient setting at 1 month and every 3 months. The total follow-up period is one year.
Primary outcome measure
1. Severity of ARDS and septic shock, assessed using APACHE II score at baseline
2. Organ function, assessed daily using SOFA score once daily from enrollment and until freedom from critical condition
3. GCS level, PaO2/FiO2, vital signs, level of serum Cr, ALT, total bilirubin, PT, APTT, platelet count, CRP, and lactate, measured using blood sample once daily from starting treatment
4. In-hospital mortality and 30-day mortality
5. Immune function and cytokine level assessed at baseline, the first 3 days, and one week later
Secondary outcome measures
Adverse events including immune response to stem cell therapy, hyperreactivity to HUCDMSC, anaphylactic shock, or incidental malignancy after cell-based therapy. After discharge, patients will be followed up regularly in the outpatient setting at 1 month and every 3 months. The total follow-up period is one year.
