Abstract:
:BACKGROUND TruGraf is a blood-based biomarker test that measures differential expression of a collection of genes that have been shown to correlate with surveillance biopsy results. However, in the majority of U.S. transplant centers, surveillance biopsies are not performed. The objectives of this study were to evaluate the clinical validity of TruGraf in stable kidney transplant recipients and to demonstrate the potential clinical utility of serial TruGraf testing in a center not utilizing surveillance biopsies. MATERIAL AND METHODS Serum creatinine levels, TruGraf testing at multiple time points, and subsequent clinical follow-up were obtained for 28 patients. RESULTS Overall concordance of TruGraf results, when compared with independent clinical assessment of testing, was 77% (54/70) for all tests; 79% (22/28) for test 1, 75% (21/28) for test 2, and 79% (11/14) for test 3. The negative predictive value (NPV) was 98.0%. Analysis of clinical utility indicated that 77% of TruGraf results would have been useful in patient management. CONCLUSIONS Our results indicate the value of serial TruGraf testing in those transplant centers that do not perform surveillance biopsies as part of their standard of care. The high negative predictive value indicates the ability of TruGraf to confirm immune quiescence with a high degree of probability in patients with a Transplant eXcellence (TX) result, without the need to perform a surveillance biopsy.
