Brief Summary:
Detecting allograft injury and rejection is critical to preventing graft loss. The current standard of care (SoC) relies on serum creatinine (SC) and biopsy to monitor for and identify kidney injury earlier. SC has poor specificity and sensitivity and response to rejection is often delayed. Protocol biopsy is more accurate but involves the risk of complications. A more definitive, less invasive method for monitoring injury and early rejection is needed.
We report on the clinical utility of donor-derived cell-free DNA (dd-cfDNA) in transplant recipients' blood, measured using a novel SNP-based mmPCR NGS methodology, to diagnose allograft injury/rejection. In this study, investigators will measure how use of dd-cfDNA changes clinical practice.

Detailed Description:
Five-year kidney allograft survival rates are estimated to be as low as 71.6%. A leading cause for the high prevalence of graft loss is the delay in detecting allograft injury from active rejection, when early diagnosis and intervention presents the greatest chance of preserving kidney function. Despite the frequent testing called for by care protocols, low levels of injury can go undetected due to the low specificity and sensitivity of current, standard testing methods: checking creatinine and immunosuppressive drug levels. More definitive graft biopsies are an option, but they are invasive, expensive and can even put the patient at risk for graft loss and other complications, making it undesirable as a frequent monitoring test.
Donor-derived cell-free DNA (dd-cfDNA) detected in the blood of transplant recipients has been shown to be a non-invasive diagnostic marker for allograft injury/rejection. Natera, Inc. has recently developed a novel single nucleotide polymorphism (SNP)-based mmPCR NGS methodology to measure dd-cfDNA in kidney transplant recipients for the detection of allograft injury and rejection. As a growing leader in the diagnostic space, Natera has commissioned a randomized controlled trial to determine the clinical utility of its dd-cfDNA detection methodology for practicing nephrologists treating kidney allograft patients. This study is expected to fill a gap in the evidence base on the clinical utility of dd-cfDNA testing for allograft rejection.
The study is a pre-post, two round controlled trial of care practices in a nationally representative sample of practicing nephrologists randomly assigned to a control or an intervention arm. All participants will be asked to propose care for a total of 6 CPV simulated patients who are adults aged 30-75; three or more months post-transplant; and presenting with signs, symptoms and laboratory findings suggestive of allograft rejection. Each assessment round will consist of 3 simulated patients. In between assessment rounds, participants randomized into the intervention arm will receive educational materials on the new allograft rejection test.
Investigators will assess whether practicing nephrologists more effectively identify and manage patients with possible kidney allograft rejection when given access to Natera's novel SNP-based mmPCR-NGS test that measures dd-cfDNA, and, whether those behavioral changes improves patient management and optimizes resource utilization.
