The Treatment of Bioartificial Liver With hiHep Cells After Extensive Hepatectomy

June 23, 2025 updated by: Xiujun Cai, Sir Run Run Shaw Hospital

A Clinical Study of hiHep Cells for Bioartificial Liver After Extensive Hepatectomy

It is a prospective, non-randomized, single-arm cohort study. A total of 10 patients will be included in this study. Based on standardized treatment, the treatment of bioartificial liver device will be applied 48-72 hours after extensive hepatectomy. The bioartificial liver device consists of clinical-grade human-induced hepatocytes (hiHep) generated from human fibroblasts via transdifferentiation. In order to evaluate the security and effectiveness of the device, liver function, liver volume, the incidence of liver failure and other results will be analyzed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Experimental: extensive hepatectomy patient
hiHep bioartificial liver therapy
Biological: hiHep bioartificial liver therapy
HiHep cell bioartificial liver treatment was performed 48-72 hours after extensive hepatectomy. Temporary hemodialysis tube for large vein (jugular vein or femoral vein) is indwelled before treatment. Before treatment, prepare hiHeps-BAL in a biological safety cabinet that meets clinical standards, connect the corresponding tubing to the Jianfan DX-10 blood purification machine, and prefill with heparin saline. Half an hour before treatment, the patient was pre-heparinized (heparin about 600iu) and dexamethasone to prevent allergic reactions. The patient enters the ICU, the monitor is connected to the corresponding pipeline, the arterial pump 120-160ml/min, the slurry pump 30-40ml/min, the circulating pump 75-100ml/min, the duration is 4-6h.
