Can a cell test free liver transplant patients from lifelong drugs?
NCT ID NCT07735650
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial investigates whether liver transplant recipients who have a high degree of their own cells in the donor liver can safely stop or reduce their anti-rejection medications. Participants with stable liver function for at least five years will have a liver biopsy to measure cell chimerism. Those with high chimerism will attempt to withdraw immunosuppression entirely, while others may reduce their dose. The goal is to see if chimerism can identify patients who no longer need lifelong anti-rejection drugs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- immunosuppression withdrawal or minimization guided by liver cell chimerism testing
- What this could lead to
- If successful, this could allow some liver transplant recipients to safely stop or reduce lifelong anti-rejection drugs, avoiding their side effects.
- What could go wrong
- This is an early exploratory trial with only 60 participants. Withdrawing immunosuppression carries a risk of organ rejection, and the chimerism threshold may not reliably predict tolerance.
