Description

Summary

To evaluate the association between time-updated CMV and BK viral loads measured monthly by T-ID and the risk of CMV disease and/or biopsy-proven BK virus-associated nephropathy (BKVAN) during the first 12 months following kidney transplantation, accounting for the net immune environment (TTV viral load) and allograft injury (donor-derived cell-free DNA, dd-cfDNA).

Official Title

A Prospective, Multicenter, Observational Study Evaluating Serial T-ID Monitoring for the Prevention of CMV Disease and BK Virus-Associated Nephropathy Following Kidney Transplantation

Details

  • To characterize time-updated viral detection patterns (e.g., transient vs sustained CMV or BK signals) identified by T-ID prior to development of CMV disease or BKVAN.
  • To evaluate the clinical utility of T-ID monitoring, defined by the frequency and type of clinical management actions taken following test results.
  • To estimate the diagnostic performance of T-ID for clinically meaningful viral infection compared with standard-of-care (PCR) testing and clinical adjudication.
  • To quantify lead time between T-ID detection of viral cfDNA and standard-of-care confirmation or initiation of therapy.
  • To assess the safety of biomarker-informed management, including both rejection following infection-directed management and infection following rejection-directed management.

Open to people ages 18 years and up

  • Participants must meet all the following criteria:
    • Written informed consent and HIPAA authorization obtained prior to any study-related data collection.
    • Age ≥18 years at the time of enrollment.
    • Recipient of a kidney transplant, including:
    • Primary or repeat kidney transplantation
    • Living-donor or deceased-donor transplantation
    • At 1 month post-kidney transplant at the time of enrollment.
    • Receiving maintenance immunosuppressive therapy per institutional standard of care.
    • Selected by the treating provider to undergo TRAC testing as part of usual post-transplant clinical monitoring.

You CAN'T join if...

  • Recipient of a combined organ transplant involving a non-renal solid organ (e.g., kidney-liver, kidney-heart) and/or islet cell transplantation.
  • History of prior non-renal solid organ transplantation or islet cell transplantation.
  • Known pregnancy at the time of enrollment.
  • Known active viral infection at enrollment with any of the following:
  • Hepatitis B surface antigen (HBsAg)-positive
  • Hepatitis B virus (HBV) nucleic acid testing (NAT)-positive
  • Human immunodeficiency virus (HIV) infection or HIV NAT-positive
  • *Known active BK virus-associated nephropathy (BKVAN) or CMV disease at the time of enrollment.
  • Medical, psychiatric, or social condition that, in the opinion of the Investigator, would interfere with the participant's ability to provide informed consent or comply with study procedures.
  • Concurrent participation in another investigational biomarker study designed to evaluate clinical utility of post-transplant molecular diagnostics.
    • Participants with asymptomatic or low-level viral replication detected during routine clinical monitoring are eligible, provided there is no evidence of established CMV disease or BK virus-associated nephropathy at enrollment.
