Micro-encapsulated Hepatocyte Intraperitoneal Transplantation in Liver Failure Adults

Recruiting now · Phase 1

Conditions studied: Acute-On-Chronic Liver Failure, Chronic Liver Failure

In brief

This is a prospective single-center dose escalation study of the administration of the microencapsulated hepatocyte therapy in adult liver failure. The purpose of the study is to determine the maximum tolerated dose of microencapsulated hepatocytes in liver failure patients and its effectiveness in treating the disease. We previously generated proliferating human hepatocytes (ProliHH) through dedifferentiation of PHH and engineered them into encapsulated liver organoids (eLO), providing an unlimited cell source for hepatocyte transplantation.
