FDA Grants De Novo Marketing Authorization for KidneyIntelX.dkd to Assess Risk of Progressive Kidney Function Decline in Adults with Diabetes and Early-Stage Kidney Disease
Simple Blood Test Aids Risk Assessment for Approximately 14 Million Eligible Patients in the United States
Diabetic Kidney Disease is the Leading Cause of End Stage Kidney Disease in the United States
LONDON and SALT LAKE CITY, June 29, 2023 (GLOBE NEWSWIRE) -- Renalytix plc (LSE: RENX) (NASDAQ:RNLX) announces that the U.S. Food and Drug Administration (FDA) has granted De Novo marketing authorization for its KidneyIntelX.dkd ™ prognostic test. This affirms KidneyIntelX as a first-in-class, artificial intelligence enabled prognostic testing platform to guide care management for adults with type 2 diabetes and early-stage chronic (diabetic) kidney disease. Renalytix believes FDA authorization will lead to increasing test adoption, informing clinical guidelines, expanding insurance coverage, and pursuing additional international regulatory approvals.
“Meeting the rigorous safety, clinical and analytical validation, and scientific data requirements of an FDA review, from Breakthrough Device designation to De Novo marketing authorization, is a landmark event for health care providers and patients with diabetic kidney disease,” said James McCullough, CEO of Renalytix. “With this approval a new class, Prognostic Test for Assessment of Chronic Kidney Disease Progression, has been established by the FDA, providing a roadmap for future expansion of KidneyIntelX into new indications and products.”
KidneyIntelX.dkd accurately stratifies patients into three risk levels (low, moderate, and high). This result provides comprehensive information on patient risk for progressive decline in kidney function within five years, independently of the current standard of care measures. KidneyIntelX.dkd is the name used to differentiate tests to be provided under the De Novo marketing authorization by the FDA from those provided under the KidneyIntelX name as a Laboratory Developed Test.
Since being introduced as a Laboratory Developed Test (LDT), KidneyIntelX results have been reported on approximately 10,000 patients in the United States and there has been broad insurance payment including from Medicare and many private payers.
The KidneyIntelX platform combines blood-based biomarkers with clinical variables using an artificial intelligence enabled algorithm, providing reliable and actionable information to guide care in large, at-risk patient populations. KidneyIntelX is based on technology developed at the Icahn School of Medicine at Mount Sinai in New York, NY, and licensed to Renalytix.
About Chronic (Diabetic) Kidney Disease
Kidney disease is now recognized as a public health epidemic affecting over 850 million people globally. The Centers for Disease Control and Prevention (CDC) estimates that 15% of US adults, more than 38 million people, currently have chronic kidney disease (CKD). Diabetes is the leading cause of kidney failure, accounting for 44% of new cases. Further, the CDC reports that 9 out of 10 adults with CKD do not know they have it and one out of two people with very low kidney function who are not on dialysis do not know they have CKD.1 Kidney disease is referred to as a "silent killer" because it often has no symptoms and can go undetected until a very advanced stage. Each year, kidney disease kills more people than breast and prostate cancer. Every day, 13 patients in the United States die while waiting for a kidney transplant.
About Type 2 Diabetes
More than 37 million Americans have diabetes (about 1 in 10), and approximately 90-95% of them have type 2 diabetes. Type 2 diabetes most often develops in people over age 45, but more and more children, teens, and young adults are also developing the disease2. Type 2 diabetes symptoms often develop over several years and approximately 23% of adults with Type 2 Diabetes are undiagnosed3. Type 2 diabetes affects many major organs, including the heart, blood vessels, nerves, eyes and kidneys. Diabetic Kidney Disease develops in 30-50% of Type 2 diabetes patients4.
Renalytix (NASDAQ: RNLX) (LSE: RENX) 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 technology platform to introduce novel laboratory developed and FDA approved tests to enable risk assessment and appropriate care management in adult patients with type 2 diabetes and early-stage CKD. By gaining early visibility into risk for progressive decline in kidney function, and an understanding of associated actionable insights, patients and health care providers may benefit from improved outcomes and decreased costs.
