Business Update

LONDON and SALT LAKE CITY, March 27, 2023 - Renalytix plc (NASDAQ: RNLX) (LSE: RENX) provides the following business update.

Renalytix has further expanded its insurance coverage base for KidneyIntelX in the Northeast region of the United States with the execution of a coverage contract with EmblemHealth, one of the nation's largest not-for-profit health insurers serving over three million people in the New York Tri-State area. 

The EmblemHealth contract and other previously established insurance coverage contracts including Healthfirst, Capital District Physicians Health Plan and Connecticare, build on the comprehensive insurance coverage portfolio necessary to transition to a full commercial payment model for KidneyIntelX prognostic testing in the New York and Connecticut state regions.

As previously disclosed on the Company's November 2022 quarterly earnings call, Renalytix is pursuing a strategy to achieve insurance coverage for KidneyIntelX for a majority of patients in specific United States regions containing large populations living with diabetes and kidney disease. Management believes achieving insurance payment for a majority of the population in KidneyIntelX's indicated use is essential for adoption to proceed.  This is particularly important at a primary care or generalist physician level where KidneyIntelX testing is focused, as patients and doctors need to have a clear understanding of test billing practices and the amount of patient financial obligation, if any, once a test is performed.

Renalytix is working with health systems, as well as public and private payers to implement care models informed by KidneyIntelX early risk assessment in patients with diabetes and kidney disease to improve kidney health and reduce the number of dialysis starts.

Real-world evidence data from a large prospective study at Mount Sinai Health System in New York evaluating KidneyIntelX in the primary care setting published in the Journal of Primary Care Community Health in December 2023 demonstrated use of KidneyIntelX resulted in an increase in appropriate therapeutic management, timely specialist consultation or referral and observed improvements in HbA1C (diabetes health) in the high risk groups and UACR (kidney health) in the low and intermediate risk groups in as little at 6 months in patients with kidney disease and diabetes.  Additional results from ongoing multi-center real world evidence studies on KidneyIntelX are expected to be released this summer.  

This announcement contains inside information for the purposes of Article 7 of Regulation (EU) 596/2014 (MAR).

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 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 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™ 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.

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.
