Pivotal kidneyintelX.dkd data published

LONDON and NEW YORK, 12 November 2025 - Renalytix plc (LSE: RENX) (OTCQB: RNLXY), a precision medicine diagnostics company, with kidneyintelX.dkd, the only FDA-approved and Medicare reimbursed prognostic test to support early-stage risk assessment in chronic kidney disease, announces a manuscript titled "Baseline Risk and Longitudinal Changes in kidneyintelX.dkd and Its Association With Kidney Outcomes in the CANVAS and CREDENCE Trials" has been published in the highest ranked diabetes journal globally, Diabetes Care, from the American Diabetes Association.

The study was co-authored by global thought leaders from Europe, US and Australia and included analysis of the kidneyintelX.dkd test in a combined cohort of 2,954 subjects from the completed CANVAS and CREDENCE clinical trials meeting the intended use of the test. Among a number of significant findings reported, are the following:

• kidneyintelX.dkd provides improved risk classification across all of the established risk groups as presented in the KDIGO clinical guidelines
• Treatment with SGLT2i front line therapy in patients classified as moderate or high risk by kidneyintelX.dkd resulted in a significant risk reduction, with the high risk treated group twice as likely to reduce their kidneyintelX.dkd risk level at 1 year compared to those not receiving treatment.

The authors concluded that kidneyintelX.dkd facilitated the identification of patients most likely to respond to therapy through personalized risk assessment with the potential for monitoring in clinical practice and a role in future clinical studies.

Associate Professor Brendon Neuen of The George Institute for Global Health, Sydney, who co-authored the paper, commented: "With multiple recent breakthroughs in therapies to reduce kidney function decline, the time for risk-based implementation in CKD has arrived. Incorporating novel biomarkers, as done with kidneyintelX.dkd, holds strong promise to guide risk-based care. The data published in this study provides a compelling example of how we can build on well established clinical parameters to deliver more personalized care and reduce the risk of adverse clinical outcomes."

Associate Professor Brendon Neuen is an internationally recognised expert on cardio-kidney-metabolic health. He is Program Lead, Renal and Metabolic at The George Institute for Global Health and a Staff Specialist Nephrologist and Director of Kidney Trials at Royal North Shore Hospital (full biography available below).

This most recent kidneyintelX.dkd publication co-incides with the presentation of three abstracts at ASN Kidney Week, held in Houston Texas from November 5-9. A summary of these abstract are as follows;

• PO0330: Successful Implementation of KidneyIntelX in a Large Integrated Health System for Risk-Based Management of Diabetic Kidney Disease

The abstract highlighted a framework for deployment of kidneyintelX.dkd and precision medicine into a large integrated health system to achieve sustained population and patient level adoption, thereby eliciting personalised improvements in care management.

• PO0331: Decision Impact Study of kidneyintelX.dkd on provider management and patient engagement in a community care practice environment

87% of patients reported improved understanding of their kidney risk and 98% found the kidneyintelX.dkd test helped in understanding their kidney and importance of overall health. 86% of physicians in this community setting reported the test result informed care management decisions.

• PO0332: Comparison of kidneyintelX.dkd and KFRE for Predicting Progression of Diabetic Kidney Disease

The kidneyintelX.dkd test outperformed the Kidney Failure Risk Equation (KFRE) in predicting decline in kidney function or kidney failure in patients with DKD. The demonstrated improved discrimination and performance of kidneyintelX.dkd compared with the known variability in the KFRE routine clinical features, highlighted the utility of the kidneyintelX.dkd test, particularly in early stage disease.

Taken together, these data presentations reinforce the incremental and consistent value of the kidneyintelX.dkd test as a standard for precision medicine in CKD, and as a core element of integrated care management across multiple health care settings ultimately, driving significant improvements in patient care and health outcomes.
