About this trial

Demonstrate the relationship between DD-cfDNA levels and HLA antibodies in blood, and the Molecular Microscope® (MMDx) Diagnostic System results in indication biopsies.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

All kidney transplant recipients undergoing a kidney biopsy for clinical indications, as determined by their physician or surgeon, will be eligible to enroll in the study.

Disqualifiers

Patients will be excluded from the study if they decline participation or are unable to give informed consent or multiple organ recipients.

Trial population

The study population includes patients with a functioning kidney transplant undergoing a biopsy for clinical indications as standard of care to determine the cause of their graft dysfunction (deterioration in graft function, delayed graft function, proteinuria).

Trial outcomes

Primary outcomes

1

Calibration of Prospera test for T cell-mediated rejection

Calibration of DD-cfDNA test cut-off values against the probability of T cell-mediated rejection in the biopsy as reported by MMDx.

Time frame
18 months
2

Calibration of Prospera test for antibody-mediated rejection

Calibration of DD-cfDNA test cut-off values against the probability of antibody-mediated rejection in the biopsy as reported by MMDx.

Time frame
18 months
3

Calibration of Prospera test for kidney injury

Calibration of DD-cfDNA test cut-off values against the probability of acute and chronic kidney injury in the biopsy as reported by MMDx.

Time frame
18 months
4

Report calibrated Prospera test results for rejection

Report new DD-cfDNA test cut-off values for rejection

Time frame
6 months

Secondary outcomes

1

Determine if Prospera blood test can replace kidney biopsy test

Determine if Prospera test, as calibrated by this DD-cfDNA-HLA-MMDx study, will avoid need for indication biopsy when kidney transplant function deteriorates. This will be based on the consensus between participating clinicians.

Time frame
6 months
2

Assessment of donor-specific antibody status

Report and compare the DSA status based on centralized and local HLA antibody measurement.

Time frame
6 months
