Description

Summary

This is an observational study to evaluate safety and efficacy outcomes in renal transplant recipients in whom post-transplant care is managed using AlloSure®. AlloSure® is a non-invasive test to measure donor-derived cell-free DNA (dd-cfDNA). The AlloSure test is intended to assess the probability of allograft rejection in kidney transplant recipients with clinical suspicion of rejection and to inform clinical decision-making regarding the necessity of renal biopsy in such patients at least 2 weeks post-transplant in conjunction with standard clinical assessment.

Details

The AlloSure test has been approved for Medicare coverage for clinical use when a physician determines there is a need to assess the probability of allograft rejection in kidney transplant recipients. Accurate and timely detection of allograft rejection and effective treatment are essential for long-term survival of renal transplants. The DART study validated the ability of the non-invasive AlloSure test to measure donor-derived cell-free DNA (dd-cfDNA) to discriminate active rejection in a renal transplant recipient. Use of the test will inform and may reduce invasive percutaneous renal biopsy procedures among patients with risk of rejection.

KOAR Inclusion Criteria:

  1. Medicare-covered (Part B) renal transplant recipients selected by their providers to receive AlloSure testing as part of their practical care beginning by 2 months post-transplantation.
  2. Patient's health care provider adopts and intends to apply the center's AlloSure Routine Testing Schedule as part of the information used to manage the patient.
  3. Subjects willing to provide written informed consent to participate.

KOAR Exclusion Criteria:

  1. Renal transplant recipients without Medicare (Part B) coverage.

Exclusions for AlloSure® Intended Use

Specimens from patients for whom any of the following are true will not be tested:

  1. Recipients of transplanted organs other than kidney
  2. Recipients of a transplant from a monozygotic (identical)
  3. Recipients of a bone marrow transplant
  4. Recipients who are pregnant
  5. Recipients who are under the age of 18
  6. Recipient who are less than 14 days post-transplant

    After completing my Nephrology Fellowship at Albert Einstein Medical Center in Philadelphia in 2002, I joined the faculty at Drexel University College of Medicine until 2004 when I returned to Einstein as a Transplant Nephrologist. Subsequently I became the Medical Director of the Kidney Transplant Program at Einstein from 2009 - 2013.
