Clinical Trial of Umbilical Cord Mesenchymal Stem Cell Transfusion in Decompensated Liver Cirrhosis

May 7, 2018 updated by: Shandong Qilu Stem Cells Engineering Co., Ltd.

A Prospective Multicenter Clinical Study to Evaluate The Safety and Efficiency of Human Umbilical Cord Mesenchymal Stem Cell Transfusion in Patients With Decompensated Liver Cirrhosis.

Decompensated liver cirrhosis is one of the life-threatening complication of chronic liver disease. Liver transplantation currently is the only effective method that can improve the survival of these patients. However, the severe shortage of donor livers, high cost, and potential serious complications have restricted the availability of liver transplantation.Umbilical cord mesenchymal stem cells (UC-MSC) has been generally shown to be safe and effective for liver diseases in some pre-clinical and clinical studies. This study aim to evaluate the safety and efficiency of human umbilical cord mesenchymal stem cell transfusion in patients with decompensated liver cirrhosis, and explore the best protocol of MSC transfusion.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a multicenter non randomized control study. Patients with decompensated liver cirrhosis are going to be assigned to receive standard medical care plus UC-MSC treatment with two different protocol (group 1 and group 2) or standard medical care (control). Four times of MSC infusion (1.5x10E6 cells/kg body weight) via peripheral vein will be given to the group 1（once every 4 days), and two times of MSC infusion once every 7 days to the group 2. The primary outcome is survival rates in one year. Secondary outcomes are liver function, liver ascites and MELD score.
