Safety and Efficacy Study of Regulatory T Cells in Treating Autoimmune Hepatitis (Treg)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

Brief Summary:
Separated and expanded the CD4+CD25+CD127- Tregs from peripheral blood of autoimmune hepatitis patients and administrate the cells (5 x 106 cells/kg) into patients.

Condition or disease Intervention/treatment Phase
Autoimmune Diseases Biological: Regulatory T cells Phase 1 Phase 2

Detailed Description:

The trial will be carried out in autoimmune patients. The investigators will isolate CD4(cluster of differentiation)+CD25(cluster of differentiation25)+CD127(cluster of differentiation127)- Tregs from these patients, and expand them with IL(interleukin)-2 retinoid acid and anti-CD3(cluster of differentiation 3) /CD28(cluster of differentiation 28) beads. The patients will be subsequently treated with single infusion of CD4+CD25+CD127- Tregs (10-20 x 106 cells/kg).

In the clinical trials, the investigators will monitor the number of Tregs in patients at different periods, and to test their suppressive functions in vitro. Also the function and biopsy of liver will be processed to determine the efficacy of Treg therapy.

Arm Intervention/treatment
Experimental: Regulatory T cells
CD4(cluster of differentiation)+CD25+CD127- T cells isolated from peripheral blood mononuclear cells were be expanded with GMP(Good Manufacturing Practice) anti-CD3/CD28 coated beads in the presence of IL-2 and all-trans retinoid acid.
Biological: Regulatory T cells
Regulatory t cells will be injected back to autoimmune hepatitis patients




Primary Outcome Measures :
  1. Biochemical remission(serum levels of alanine aminotransferase, aspartate aminotransferase and Total bilirubin within normal ranges) [ Time Frame: 12 months ]
  2. immunology remission(=serum levels of T cell subsets, immune globulin, and complement within normal ranges) and lack of other side effects. [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. Incidence of biochemical remission 2 times increase of serum levels of alanine aminotransferase, aspartate aminotransferase and Total bilirubin. [ Time Frame: 12 months ]
  2. Suspected rejection detected by clinical feature or biopsy. [ Time Frame: 12 months ]
  3. Incidence of 2 times increase of immunology related level(serum levels of T cell subsets,immune globulin) or present other side effects. [ Time Frame: 12 months ]
