Clinical Trial of Mesenchymal Stem Cells in the Treatment of Severe Acute Kidney Injury
Study Details
Study Description
Brief Summary
Acute kidney injury(AKI) is a common, severe emergency case in clinics,especially severe AKI ,which is associated with higher morbidity and mortality. Effect of routine therapy is limited and mesenchymal stem cells (MSC)are considered a new therapy for treating severe acute kidney injury. Patients will be randomized to receive intravenous infusion of MSC, or placebo control. This trial is to investigate whether MSC can improve renal recovery and mortality of patients with AKI.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Mesenchymal stem cells cohort

Biological: Mesenchymal stem cells
In experimental group, patients receive standard treatment and allogeneic human umbilical cord derived-mesenchymal stem cells (MSCs) is administered via intravenous infusion on day 0 and day 7

| Placebo Comparator: Saline cohort
|
Other: Saline
In placebo control group, patients receive standard treatment and saline is administered via intravenous infusion on day 0 and day 7

Outcome Measures
Primary Outcome Measures
- The difference in the renal function between the two groups (MSC treatment group vs placebo control group) within 28 days after receiving MSC/ placebo treatment [within 28 days after receiving MSC/ placebo treatment]
Compare the creatinine concentration between the two groups (MSC treatment group vs placebo control group) at 28 days after receiving MSC/ placebo treatment.
Secondary Outcome Measures
- Overall survival within 28 days after receiving MSC/ placebo treatment [28 days]
Compare the overall survival rate between the two groups (MSC treatment group vs placebo control group) at 28 days after receiving MSC/ placebo treatment.
- Overall survival within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the overall survival rate between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/ placebo treatment.
- Renal replacement therapy (RRT) dependent within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the rate of renal replacement therapy (RRT) dependence between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/ placebo treatment.
- Complete renal recovery within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the rate of complete renal recovery between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/placebo treatment. We considered complete recovery as alive, free of RRT, and the SCR decreased to no more than 1.5 times of the baseline level.
- Partial renal recovery within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the rate of partial renal recovery between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/placebo treatment. Partial recovery refers to survival, free of RRT, and the SCR 1.5 times higher than the baseline level of creatinine.
- ICU and hospitalization duration of stay among all AKI patients within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the days in ICU and hospital between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/placebo treatment.
- Adverse events within 3 months after receiving MSC/ placebo treatment [3 months]
Compare the rate of adverse events between the two groups (MSC treatment group vs placebo control group) at month 3 after receiving MSC/placebo treatment.
