Validation of Genomic Immune-phenotyping Profiles to Predict Risk of Kidney Transplant Rejection

Validation of Genomic Immune-phenotyping Profiles in Peripheral Blood Gene Signatures to Predict Risk of Kidney Transplant Rejection

Global, non-randomized, observational study for the validation of Verici Dx genomic tests to predict risk of kidney clinical and subclinical acute rejection, and chronic allograft damage or interstitial fibrosis / tubular atrophy by correlating peripheral blood gene expression profiles with graft injury (e.g. cellular / antibody-mediated), rejection and death censored graft loss.

Study Overview

• Status: Active, not recruiting
• Conditions: Kidney Transplant Rejection

Detailed Description

The study is correlative and observational and will involve collecting clinical and pathological data along with blood, biopsy tissue and urine during standard routine scheduled medical visits for transplant preparation or monitoring. The blood will be used for next generation sequencing in the Verici Dx laboratory to create transcriptomic profiles to validate performance characteristics of three Verici Dx sequencing immune-phenotype signature risk score tests. The research biopsy tissue and urine are for secondary or exploratory objectives. To allow comparison with current accepted standard approaches to identify kidney transplant injury or rejection, digital images of stained tissue sections taken from surveillance or for-cause biopsy tissue will be evaluated in a central pathology laboratory for the purposes of this study. Enrolled subjects will continue in the study for 24 months during which the planned validation of the acute clinical and subclinical rejection tests will complete after 6 months of follow-up; subjects will be followed to 24 months for the validation of the Verici Dx blood-based fibrosis risk prognostic test. After 24 months, patients will be followed through ANZDATA and UNOS registry data for later development of fibrosis or for graft loss or death.
