Micro-encapsulated Hepatocyte Intraperitoneal Transplantation in Liver Failure Adults

"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."
