A Phase 1/2 interventional study of Chemically induced pluripotent stem cells biological Artificial Liver in Liver Failure and Small-for-Size Syndrome, sponsored by Beijing Friendship Hospital. Recruiting at 1 site in China. Per ClinicalTrials.gov, last updated 2026-04-20.
Sponsored by Beijing Friendship Hospital · Phase 1/2, Interventional, and Treatment
The goal of this clinical trial is to evaluate the safety and tolerability of a novel bioartificial liver (CiPS-BAL) in patients with liver failure or small-for-size syndrome. The study will also collect preliminary data on clinical outcomes and laboratory parameters during treatment. The main questions it aims to answer are:
Is the novel bioartificial liver system safe and well tolerated in patients with liver failure or small-for-size syndrome?
What effects does the treatment have on liver function and other clinical and laboratory indicators?
Researchers will treat participants with the CiPS-BAL system, which uses hepatocytes derived from chemically induced pluripotent stem cells (CiPS) within a bioartificial liver device.
190 studies on the registry are indexed under Liver Failure; 33 are open to participants now.
This study's planned enrollment of 12 is below the median of 57 across 113 interventional studies indexed under Liver Failure.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Chemically induced pluripotent stem cells biological Artificial Liver
Biological: Chemically induced pluripotent stem cells biological Artificial Liver
Participants will receive CiPS-BAL therapy, a novel bioartificial liver treatment that combines functional hepatocytes derived from chemically induced pluripotent stem cells (CiPS) with an extracorporeal bioartificial liver device. The CiPS-derived hepatocytes are generated and cultured in vitro under Good Manufacturing Practice (GMP) conditions and subsequently loaded into the bioartificial liver device prior to treatment. Each treatment session utilizes 1 × 10¹⁰ functional hepatocytes. Therapy is administered via central venous access (e.g., femoral, internal jugular, or subclavian vein) for 4-8 hours per session. The planned treatment frequency is one session, with the possibility of additional sessions depending on clinical response and safety evaluation. Standard medical therapy for liver failure or small-for-size syndrome will be provided concomitantly. Participants will be closely monitored for safety, tolerability, and changes in clinical and laboratory parameters throughout
