Safety Study of Liver Regeneration Therapy Using Cultured Autologous BMSCs

Yamaguchi University Hospital10 enrolled

Overview

Patients eligible for this study include those with decompensated liver cirrhosis with a Child-Pugh score ≥7 (Child-Pugh B) in whom further improvement with current medical treatment is not expected. Other inclusion criteria are age 20 to 75 years and a serum total bilirubin of 3.0 to 5.0 mg/dL, or if the total bilirubin is \<3.0 mg/dL, patients who are still deemed unsuitable as a candidate for general anesthesia. About 30 mL of autologous bone marrow was collected from the bilateral iliac crests under local anesthesia, heparin was added after collection. In addition, at the Center for Regenerative and Cell Therapy at Yamaguchi University Hospital, a nucleated cell fraction was prepared. Next, a cell suspension was prepared by adding culture medium, and this was inoculated into a culture flask. After subculturing for 3 weeks, the cells were infused through a peripheral vein. The primary endpoint is the incidence of adverse events up to 24 weeks after ABMSC infusion.
