Using donor-derived DNA and immune cells to predict kidney transplant rejection

Official title: Integration of Donor-derived Cell-free DNA With HLA-DR+TNFR2+ Regulatory T Cell in the Prediction of Acute Rejection and Graft Function After Kidney Transplantation

Run by Loma Linda University · NCT05084768 · Data updated 2026-11-12

This study is testing if measuring certain DNA and immune cells from kidney donors can help predict if a kidney transplant will be rejected by the recipient's body.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adult kidney transplant candidates or recipients.

Probably not a fit

Patients under 18, those undergoing multi-organ transplants, or those with HIV or HCV may not benefit from this study.

What this trial studies

This observational study aims to improve the prediction of acute rejection in kidney transplant recipients by analyzing donor-derived cell-free DNA (dd-cfDNA) and regulatory T cells (Tregs). The study will evaluate how levels of dd-cfDNA and specific Treg populations correlate with acute rejection events, particularly focusing on their predictive capabilities for both high and low severity rejections. By identifying these biomarkers, the study seeks to enable non-invasive monitoring of transplant health, potentially leading to timely interventions that could enhance long-term graft survival.

Why it matters

Potential benefit: If successful, this approach could lead to earlier and more accurate detection of kidney transplant rejection, improving patient outcomes and graft longevity.

How similar studies have gone: Other studies have shown promise in using dd-cfDNA for predicting transplant rejection, but this specific integration of dd-cfDNA with Treg analysis is relatively novel.
