ID-ENTITY Trial- Evaluating Serial T-ID Monitoring (ID-ENTITY)

February 20, 2026 updated by: Transplant Genomics, Inc.

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

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).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All subjects who meet eligibility criteria will be enrolled. As this is a non-interventional study, the protocol does not mandate any specific diagnostic, therapeutic, or management interventions. Clinical management decisions, including adjustments to immunosuppression, antiviral therapy, diagnostic testing, and biopsy decisions, remain entirely at the discretion of the treating clinicians.

Description

Inclusion Criteria:

  • 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.

Exclusion Criteria:

  • 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.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The primary endpoint of the study is the time to first occurrence of either cytomegalovirus (CMV) disease or biopsy-proven BK virus-associated nephropathy (BKVAN) during the first 12 months post-kidney transplantation.
Time Frame: 12 Months
  • CMV disease will be defined according to standard clinical criteria, including CMV syndrome and/or tissue-invasive CMV disease, as determined by the treating clinician and documented in the medical record.
  • BK virus-associated nephropathy (BKVAN) will be defined as biopsy-proven BK virus nephropathy, characterized by histopathologic features consistent with BKVAN (including intranuclear viral inclusions and/or positive SV40 large T-antigen staining), in the setting of documented BK viral replication by standard-of-care testing (e.g., plasma or urine PCR).

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
