Transitioning kidney transplant patients to Belatacept-only immunosuppression using DNA testing

Use of Donor Derived-cell Free DNA (AlloSure) to Facilitate Belatacept Monotherapy in Kidney Transplant Patients

Phase 4 Interventional University of Texas Southwestern Medical Center · NCT04786067

This study is trying to see if kidney transplant patients can safely switch from taking multiple immunosuppressant drugs to just one called Belatacept, using DNA testing to help guide the process.

What this trial studies

This study aims to identify kidney transplant recipients who can safely transition from multi-drug immunosuppression to Belatacept monotherapy. It utilizes cell-free DNA and gene expression markers to assess immune quiescence, focusing on the effectiveness and safety of Belatacept as a sole immunosuppressant. The primary objective is to evaluate the use of donor-derived cell-free DNA (AlloSure) in facilitating this transition, while secondary objectives include assessing the predictive value of AlloMap and iBox for immune tolerance and adverse outcomes.

Who should consider this trial

Good fit: Ideal candidates include adult kidney transplant recipients with stable renal function who have been on Belatacept for at least three months.

Not a fit: Patients with prior non-kidney organ transplants or those experiencing acute rejection episodes may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could simplify immunosuppression regimens for kidney transplant patients, potentially reducing side effects and improving quality of life.

How similar studies have performed: While the approach of using DNA testing for immunosuppression management is innovative, similar studies have shown promise in other contexts, indicating potential for success.
