Molecular Biomarkers in Renal Transplantation Via TruGraf® Test

Overview

The TruGraf® test is a non-invasive blood test that measures molecular gene expression profiles associated with clinical conditions previously only diagnosed by biopsy in kidney transplant recipients. The results of the TruGraf test provide additional information about the adequacy of immunosuppression and may be used to support decisions in patient management.

This is a single-center, prospective, randomized study to evaluate clinical utility of TruGraf testing in patients with the following characteristics:1.Stable serum creatinine: current serum creatinine \<2.3 mg/dl, \<20% increase compare to the average of the previous 3 serum creatinine levels2.Kidney transplant patients who are:•more than 60 days post-transplant will be included in this study (Study A) •more than 2-yearspost-transplant but less than 5 years post-transplant (\>24 months but \< 60 months) will be included in this study (Study B) Scripps will enroll subjects who are post-transplant and are undergoing routine management. In Study A, patients will receive testing eight times: Month 2 (at time of surveillance biopsy) 6(at time of surveillance biopsy), 9, 12(at time of surveillance biopsy), 15, 18, 21 and 24(at time of surveillance biopsy) (plus or minus two weeks). Results of the genomic analysis will be considered in determining patient treatment plans and as a molecular guide to perform a surveillance biopsy. Clinical data elements using the Scripps EHR and cost of care will be collected for all subjects. In Study B, patients who are at least 2 years post transplant up to 5 years post-transplant will receive testing 8 times: Months 3 ,6, 9, 12, 15, 18, 21 and 24 (plus or minus two weeks)from the time of enrollment into the study. Results of the genomic analysis will be considered in determining patient treatment plans and whether any change is needed, such as whether to perform a surveillance biopsy. Clinical data elements using the Scripps EHR and cost of care will be collected for all subjects. We expect Study A to be completed 24-30months and Study B to be completed in 24-30 months.
