RNLX Renalytix PLC

Renalytix plc (NASDAQ: RNLX) (LSE: RENX) announces the launch of PRIME-CKD*, a consortium of industry, academic and clinical research leaders, that aims to validate and implement in clinical practice, novel biomarker-based tests that predict response to existing drugs used by patients with chronic kidney disease (CKD). PRIME-CKD is funded by Horizon Europe, the European Union’s key funding program for research and innovation. The total budget of the project is $10 million over a projected five-year period with approximately 10% of the budget targeted for commercial translation activities to be undertaken by Renalytix.

We expect the project to benefit from Renalytix’s substantial expertise in biomarker research translation and existing intellectual property on urinary Epidermal Growth Factor (uEGF) for which Renalytix has exclusive access from the University of Michigan. The project is closely aligned with Renalytix’s objective of expanding the clinical utility of the KidneyIntelX platform beyond prognosis to prediction and monitoring of drug response.

The consortium brings together leading experts from 11 academic institutions, together with partners from patient representative foundations and regulatory agencies. A full listing of consortium members is provided below.

The PRIME-CKD consortium is committed to demonstrating the utility of novel biomarkers as tools for better selection of drug therapies for patients, for use both in daily clinical practice and innovative clinical trials. Notably, if certain biomarkers are successful, the PRIME-CKD program will seek qualification of these biomarkers through the European Medicines Agency and the United States Food and Drug Administration (FDA) for this purpose.

Hiddo J.L Heerspink, the program coordinator from the University Medical Center Groningen, Netherlands, said: “Results from this project are expected to translate into significant patient benefits and decreased societal costs associated with CKD by helping ensure that patients receive the most effective therapy, at the right time, to slow or prevent the kidney failure requiring dialysis or transplant.”

Fergus Fleming, Chief Technology Officer of Renalytix who will serve on the steering committee for PRIME-CKD and lead the implementation of the research outputs into clinical practice, added: “The opportunity to participate in the PRIME-CKD program combined with ongoing development of novel biomarkers from our collaboration with Joslin Diabetes Center and planned data generation in completed clinical studies expected in 2023, further strengthens KidneyIntelX as a precision medicine platform in CKD.”

The PRIME-CKD program builds on breakthrough findings in the Innovative Medicine Initiative 2 program BEAt-DKD (https://www.beat-dkd.eu/) which was initiated in 2016 and identified novel biomarkers of disease progression and treatment response in patients with diabetic kidney disease. “I am excited to be involved in the PRIME-CKD program which builds upon the strong kidney research pipeline and precision medicine vision developed in Europe over the last years,” said Professor Maria F. Gomez, PRIME-CKD steering committee member and coordinator of the BEAt-DKD consortium from Lund University Diabetes Centre, Sweden. The PRIME-CKD consortium will further develop the evidence-based tools and roadmap to unlock the potential of precision medicine in the management of CKD.

About Kidney DiseaseKidney disease is a public health epidemic affecting over 850 million people globally.1 The Centers for Disease Control and Prevention estimates that 15% of U.S. adults, or approximately 37 million people2, have chronic kidney disease (CKD). Nearly 95% of people with CKD are in early stages 1-33. Despite its magnitude, early-stage (1-3) CKD is underdiagnosed and undertreated, largely because it’s asymptomatic at this time in the disease. As many as 9 in 10 adults with CKD, and about 2 in 5 adults with severe CKD do not know they have the condition.3

About RenalytixRenalytix (NASDAQ: RNLX) (LSE: RENX) is an in-vitro diagnostics and laboratory services company that is the global founder and leader in the new field of bioprognosis™ for kidney health. The leadership team, with a combined 200+ years of healthcare and in-vitro diagnostic experience, has designed its KidneyIntelX laboratory developed test to enable risk assessment for rapid progressive decline in kidney function in adult patients with T2D and early CKD (stages 1-3). We believe that by understanding how disease will progress, patients and providers can take action early to improve outcomes and reduce overall health system costs. For more information, visit www.renalytix.com.

About KidneyIntelX™KidneyIntelX™ is a laboratory developed test demonstrated to be a reliable, bioprognostic™ methodology that yields a simple-to-understand, custom risk score, enabling prediction of which adult patients with T2D and early CKD (stages 1-3) are at low, intermediate or high risk for rapid progressive decline in kidney function. By combining information from KidneyIntelX with newer cardio- and reno-protective therapies, doctors will have more information in determining which patients are at higher versus lower risk for rapid disease progression and may be able to more appropriately target resources and guideline-recommended treatments to advance kidney health. KidneyIntelX is supported by a growing body of clinical, utility and health economic studies (including a validation study of two large cohorts) and has demonstrated a 72% improvement in predicting those patients who are at high risk for rapid progressive decline in kidney function versus the current standard of care (eGFR and UACR). KidneyIntelX has received Breakthrough Device Designation from the U.S. Food and Drug Administration, and Renalytix has submitted for De Novo marketing authorization.
