Primary Biliary Cirrhosis Clinical Trial
Official title:
Mesenchymal Stem Cell Transplantation for Refractory Primary Biliary Cholangitis, a Randomized Double-blind Placebo Controlled Trial
Ursodeoxycholic acid is the mainstay treatment medicine for primary biliary cholangitis(PBC). About 1/3 of the patients do not respond to UDCA, which is defined as refractory PBC. Mesenchymal stem cells (MSC) has been reported to improve the outcomes of PBC patients. Randomization controlled studies are needed to confirm the long term effect of MSC treatment for refractory PBC. This study aimed to investigate the safety and efficacy of mesenchymal stem cells in PBC patients that do not respond to UDCA treatment. This study is an double-blind multicenter randomized and placebo-controlled study. Patients with with refractory PBC will be randomly assigned to receive MSC treatment plus UDCA or UDCA alone (control). Three times of MSC infusion (0.1-1x10E6 cells/kg body weight) via peripheral vein will be given to the experimental group (once in 4 weeks). The primary outcome is absolute change in alkaline phosphatase. Secondary outcomes are changes of other liver function indices such as ALT TBIL AST GGT, improve of symptoms and liver histology.
