Summary

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.

Conditions

  • Acute-On-Chronic Liver Failure
  • Chronic Liver Failure

Interventions

BIOLOGICAL

a single course of micro-encapsulated hepatocytes intraperitoneal transplantation therapy

A single course will be divided into an "accelerated titration design" phase and a "3+3 design" phase to reduce the number of subjects exposed to potentially ineffective doses that may not benefit from treatment. The "accelerated titration design" phase starts at a starting dose of 0.15x10\^9, moving to the "3+3 design" phase at the dose of 0.5x10\^9. According to the semi-logarithmic incremental (10\^0.5-fold) approach, the treatment dosage was set into four groups at a maximum dose of 4.5×10\^9 (allowing for a ±20% difference between the actual dose and the planned dose, considering production specifics). The number or the incremental ratio of subsequent dose groups can be adjusted based on the evaluation of available data in the study, and intermediate doses can be explored.
