Clinical trial of a regenerative therapy for liver cirrhosis based on intrahepatic arterial infusion of autologous subcutaneous adipose tissue-derived regenerative (stem) cells: Protocol for a confirmatory trial
ABSTRACT
Background:
Liver cirrhosis results from chronic hepatitis, and is characterized by advanced fibrosis due to long-term hepatic inflammation. Cirrhosis ultimately leads to manifestation of jaundice, ascites, and encephalopathy, and increases the risk of hepatocellular carcinoma. Once cirrhosis is established, resulting in hepatic failure, no effective treatment is available. Therefore, novel therapies to inhibit disease progression of cirrhosis are needed.
Objective:
The objective of this investigator-initiated clinical trial is to assess the safety and efficacy of autologous adipose tissue-derived regenerative (stem) cell therapy delivered to the liver via the hepatic artery in patients with liver cirrhosis.
Methods:
Through consultation with the Japan Pharmaceuticals and Medical Devices Agency, we designed a clinical trial to assess a therapy for liver cirrhosis based on autologous adipose tissue-derived regenerative (stem) cells, which are extracted using an adipose tissue-dissociation device. The primary endpoints of the trial are the serum albumin concentration, prothrombin activity, harmful events, and device malfunction.
Results:
Enrollment and registration was initiated in November, 2017, and follow-up period ended in November, 2019. Data analysis and clinical study report will be completed soon.
Conclusions:
Completion of this clinical trial including data analysis will provide data on the safety and efficacy of this novel liver repair therapy based on autologous adipose tissue-derived regenerative (stem) cells using an adipose tissue-dissociation device. Clinical Trial: UMIN000022601
