Renalytix held Two Data Presentations on KidneyIntelX at American Diabetes Association 82^nd Scientific Sessions®

Real-world clinical utility in 1,112 patients tested with KidneyIntelX

KidneyIntelX stratification for cardiovascular risk in 1,278 diabetic kidney disease patients

NEW YORK, NY and SALT LAKE CITY, UT June 6, 2022 - Renalytix (NASDAQ: RNLX) (LSE: RENX) participated at the American Diabetes Association (ADA) 82^nd Scientific Sessions® meeting in New Orleans from June 3-7, 2022. There were two data presentations focused on the value of KidneyIntelX in care for adult patients with type 2 diabetes (T2D) and early-stage chronic kidney disease (CKD), including a late-breaking ePoster and an oral presentation.

The ePoster, "Clinical Utility of KidneyIntelX on Patients with Early-Stage Diabetic Kidney Disease-A Real-World Evidence Study" was the first time Mount Sinai Health System presented data from its real-world evidence clinical utility study with Renalytix in 1,112 patients tested with KidneyIntelX. The poster was presented to in-person and virtual conference attendees on June 5, at 12:00 p.m. CT, with commentary on behalf of the study investigators by Joji Tokita, M.D., Clinical Director, Division of Nephrology and Associate Professor of Medicine at the Icahn School of Medicine at Mount Sinai. Michael J. Donovan, Ph.D., M.D., Chief Medical Officer of Renalytix, was also on-site for commentary.  

A second oral presentation, "KidneyIntelX Association with Clinical Outcomes in Diabetic Kidney Disease" was held on June 3, at 4:45 p.m. CT by Steven G. Coca, D.O., M.S., Icahn School of Medicine at Mount Sinai, and Co-Founder of Renalytix.

"We've seen the ADA's dedication to improving kidney health in people with T2D firsthand as part of our ongoing collaboration to develop a care pathway to advance screening, diagnosis and early-stage treatment for the 40% of these patients who will develop CKD," said Tom McLain, President, Renalytix. "Chronic kidney disease can lead to significant complications for diabetes patients including cardiovascular disease and heart failure, and when left untreated can lead to dialysis and kidney transplant. Our mission is to give healthcare professionals new tools to understand an individual's risk for rapid progression of CKD, allowing them to appropriately prescribe therapeutics and to utilize specialist consultation when necessary. We look forward to joining other industry leaders at this year's Scientific Sessions in showcasing our research efforts."

The ePoster and oral presentation abstracts are available at the 2022 ADA Scientific Sessions Online Planner.

About Kidney Disease

Kidney 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 over 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 2 in 5 adults with severe CKD do not know they have the condition.²

About Renalytix

Renalytix (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^TM for kidney health. The leadership team, with a combined 200+ years of healthcare and in-vitro diagnostic experience, has designed KidneyIntelX to enable risk assessment for rapid progressive decline in kidney function in adult patients with T2D with early CKD stages 1-3 through its KidneyIntelX^TM laboratory-developed test. 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.

About KidneyIntelX^TM

KidneyIntelX^TM is a laboratory-developed test demonstrated to be a highly reliable, bioprognostic^TM methodology, that yields a simple-to-understand, custom risk score, predicting 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 a 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 also received Breakthrough Device Designation from the U.S. Food and Drug Administration and has submitted for De Novo marketing authorization.
