Brief Summary:
Acute on chronic liver failure (ACLF) is a type of critically ill liver disease with high short-term mortality in liver disease. Liver transplantation is currently the only method to improve survival. Current clinical research evidence shows that mesenchymal stem cells can reduce the mortality of ACLF patients and are safe. This study aims to explore the safety of umbilical cord mesenchymal stem cells (UC-MSCs) in the treatment of ACLF. The study population is ACLF patients with 1-2 organ failures. To explore the safety of 3 doses of UC-MSCs, 16 patients need to be enrolled. The main observation indicators are the short-term and long-term safety of the treatment. All patients need to receive the standard medical treatment (SMT) at the same time. Stem cell treatment is given by intravenous infusion on the first, fourth, seventh, and tenth day. The occurrence of adverse events (AE) and serious adverse events(SAE) before and after the infusion will be observed. After the patient is discharged from the hospital, patients will be followed , the follow-up time is 5 years.

Arm Intervention/treatment
Experimental: low dose
hUC-MSCs 4*10^5/kg/each time
 Genetic: Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs)
The hUC-MSCs were injected intravenously on the 1, 4, 7 and 10 days after patients recruitment. The treatment doses include low dose: 4*10^5 cells/kg/each time, and medium dose: 8*10^5 cells/kg/each time, high dose 12*10^5 cells/kg/each time. After 3 groups of patients were enrolled, the group with appropriate safety and effectiveness was selected and the other 4 subjects were included.
Experimental: middle dose
hUC-MSCs 8*10^5/kg/each time
 Genetic: Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs)
The hUC-MSCs were injected intravenously on the 1, 4, 7 and 10 days after patients recruitment. The treatment doses include low dose: 4*10^5 cells/kg/each time, and medium dose: 8*10^5 cells/kg/each time, high dose 12*10^5 cells/kg/each time. After 3 groups of patients were enrolled, the group with appropriate safety and effectiveness was selected and the other 4 subjects were included.
Experimental: high dose
hUC-MSCs 12*10^5/kg/each time
 Genetic: Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs)
The hUC-MSCs were injected intravenously on the 1, 4, 7 and 10 days after patients recruitment. The treatment doses include low dose: 4*10^5 cells/kg/each time, and medium dose: 8*10^5 cells/kg/each time, high dose 12*10^5 cells/kg/each time. After 3 groups of patients were enrolled, the group with appropriate safety and effectiveness was selected and the other 4 subjects were included.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safety of treatment [ Time Frame: 1 month since intervention start ]
    The purpose of this trial is to observe the short-term safety of low, medium and high doses of hUC-MSCs in the treatment of ACLF patients. The primary endpoint of the study was serious adverse events that occurred during the course of one month of treatment. If serious adverse reactions(SAE) occur during the treatment in hospital, the intervention will be stopped and the study will be terminated.


Secondary Outcome Measures :
  1. Short-time efficacy of treatment [ Time Frame: 90 days ]
    To assess the efficacy of hUC-MSCs in the treatment of ACLF patients, patients will be followed-up, and the prognosis at each time point will be collected as our schedule.
