简要总结

The goal of this clinical trial is to evaluate the safety and tolerability of multiple doses of human umbilical cord mesenchymal stem cell injection in patients with decompensated hepatitis B cirrhosis, and to further explore the efficacy, pharmacodynamic profile and appropriate dose of administration to provide a basis for the use of safer and more effective treatments for patients with decompensated hepatitis B cirrhosis in the future.

Participants are required to sign an informed consent form and, after undergoing a series of tests and meeting the protocol's entry and exclusion criteria, are assigned to a dose group for intravenous infusion of human umbilical cord mesenchymal stem cells.

详细描述

Cirrhosis decompensated stage is an advanced stage of liver disease caused by various chronic liver damages, and 77% of cirrhosis patients in China are caused by hepatitis B virus (HBV). The current treatment for patients with cirrhotic decompensation is mainly symptomatic treatment with drugs targeting the cause, anti-liver fibrosis drugs and supplemental albumin, diuresis, endoscopic sclerosis or ligation, blood purification (artificial liver) and vascular intervention. Although these treatments are effective in slowing down the progression of the disease in patients, they cannot completely reverse the decompensation of liver function in all patients. Currently, liver transplantation remains the most effective treatment for decompensated cirrhosis. However, due to the lack of donor liver sources, only a small number of patients can be treated with transplantation.

In recent years, with the in-depth research in the field of stem cells and regenerative medicine, the therapeutic role of stem cells in end-stage liver disease has received increasing attention based on their biological functions such as tissue damage repair and immune regulation. A large number of clinical exploratory studies on stem cell transplantation for liver diseases have been conducted by scholars in the field, and the published findings suggest that MSC transplantation can improve the liver function index of patients, and the appetite, mental and physical strength of patients improved significantly after infusion.

The investigators hope that the final research results will provide safe, effective and more accessible treatments for more patients in the same category, improve their quality of life and fill the gap in the field of regenerative medicine for the treatment of hepatitis B cirrhosis in the decompensated stage.

The main objective of this study was to evaluate the safety and tolerability of multiple doses of human umbilical cord MSC injection in patients with decompensated hepatitis B cirrhosis, and to further explore the efficacy, pharmacodynamic characteristics and appropriate doses for future use of safer and more effective treatments for patients with decompensated hepatitis B cirrhosis.

The test drug used in this study is called Human Umbilical Cord Mesenchymal Stem Cell Injection, and this study drug is not yet approved for marketing. This product is 10 ml, 1×100000000 cells, packaged in a cell lyophilization bag, and manufactured and supplied by Asia Cell Therapeutics (Shanghai) Co., Ltd.. The excipients of this product include dimethyl sulfoxide (DMSO), human blood albumin (HSA) and compound electrolyte injection. Quality control tests showed that the survival rate of recovered cells after lyophilization was not less than 80% within 6 hours. The cell sterility check, mycoplasma, specific human-derived virus, surface antigen and tumorigenicity were all negative. All quality control results met the requirements of the 2020 version of the Chinese Pharmacopoeia or related testing standards.
