Analyzing donor DNA in liver transplant patients

Retrospective Exploratory Analysis of Donor-derived Cell Free DNA in Liver Transplant Patients

Observational Methodist Health System · NCT06225206

This study is testing if measuring donor DNA in the blood of liver transplant patients can help doctors see if they're getting the right amount of medication to prevent organ rejection.

What this trial studies

This observational study aims to measure donor-derived cell-free DNA (dd-cfDNA) levels in liver transplant recipients who have stable liver function tests. By assessing these levels, the study seeks to determine whether patients are receiving the appropriate amount of immunosuppression medication. This non-invasive method could provide a more accurate way to monitor graft function compared to traditional liver biopsies. The ultimate goal is to optimize immunosuppression regimens and identify potential rejection early.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have undergone a liver transplant and have documented levels of donor-derived cell-free DNA.

Not a fit: Patients who have not undergone a liver transplant or do not have documented levels of dd-cfDNA will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective immunosuppression management for liver transplant patients.

How similar studies have performed: While the use of dd-cfDNA in other transplant settings has shown promise, this specific application in liver transplant patients is relatively novel and untested.
