Safety and Efficacy Study of Co-transfering of Mesenchymal Stem Cell and Regulatory T Cells in Treating End-stage Liver Disease
March 1, 2020 updated by: Ling Lu, Nanjing Medical University
Phase 1 Clinical Trial Using Mesenchymal Stem Cell and Regulatory T Cells as Individualized Medicine to Evaluate the Safety and Efficacy in End-stage Liver Disease
Cirrhosis of the liver is a common clinical chronic progressive liver disease, which is a diffuse liver lesion caused by one or more causes over a long period of time or repeatedly.
Nodules, abnormal spherical areas of cells, form as dying liver cells are replaced by regenerating cells.
This regeneration of cells causes the liver to become hard.
The potential for stem cells to differentiate into hepatocytes cells was recently confirmed.
In particular, mesenchymal stem cell (MSC) transplantation has been applicated in the clinic for treat several human diseases such as liver injury and liver fibrosis displayed good tolerance and efficiency.
Besides, regulatory T cells(Tregs) had been proved as an immune regualtory T cell subsets, which could reduce immune cell activation and reduce liver injury severity.
The purpose of this study is to learn whether and how MSCs and Tregs can improve the disease conditions in patients with decompensated cirrhosis.

Detailed Description
Cirrhosis of the liver is a common clinical chronic progressive liver disease, which is a diffuse liver lesion caused by one or more causes over a long period of time or repeatedly.
Nodules, abnormal spherical areas of cells, form as dying liver cells are replaced by regenerating cells.
This regeneration of cells causes the liver to become hard.
Decompensated liver cirrhosis is mainly manifested by liver function damage and portal hypertension, with multiple system involvement.
Complications such as upper gastrointestinal hemorrhage, hepatic encephalopathy, secondary infection, hypersplenism, ascites, and carcinogenesis often occur in the late stage.
The potential for stem cells to differentiate into hepatocytes cells was recently confirmed.
In particular, mesenchymal stem cell (MSC) and Tregs transplantation had been applicated in the clinic for treat several human diseases such as liver injury and liver fibrosis displayed good tolerance and efficiency.
The purpose of this study is to learn whether and how MSCs and Tregs can improve the disease conditions in patients with decompensated cirrhosis.

Description
Inclusion Criteria:
- Clinically diagnosed as decompensated liver cirrhosis.

- There was no history of gastrointestinal hemorrhage within the last month and population with no high-risk portal hypertension and gastrointestinal bleeding was evaluated recently.
- Unconditional acceptance of orthotopic liver transplantation.
- Aged from 18 to 65 years.
- Voluntarily signed informed consent form.
Exclusion Criteria:
- A malignant tumor with liver or other organs or a history of previous cancer.
- Complications include gastrointestinal bleeding, spontaneous peritonitis, hepatic encephalopathy, hepatorenal syndrome, and Acute infection episodes.
- Patients with severe heart, lung, kidney or blood system diseases and failure status.
- Pregnant or lactating women.
- Allergic constitution.
- There is a history of alcohol abuse, drug abuse, and failure to effectively quit.
- Patients did not participate in other clinical trials within 4 weeks.
