RenalytixAI and Joslin Diabetes Center Build on Proprietary Kidney Biomarker Portfolio for KidneyIntelX Platform

April 14, 2021

Agreement provides RenalytixAI with exclusive option to access intellectual property surrounding a comprehensive panel of novel biomarkers in kidney disease

NEW YORK, April 14, 2021 (GLOBE NEWSWIRE) -- Renalytix AI plc (LSE: RENX) (NASDAQ: RNLX) announced today that it has entered into an exclusive option agreement with Joslin Diabetes Center for patent filings on certain additional novel biomarkers in kidney disease for development and deployment in the KidneyIntelX in vitro prognostic platform.

These novel biomarkers have the potential to provide additional clinical utility for understanding early disease progression and risk of kidney failure, therapeutic response, and the mechanistic pathways of kidney disease beyond the inflammatory and tubular injury markers that are currently captured by KidneyIntelX. RenalytixAI plans to begin evaluating these novel biomarkers in expanded clinical validation studies beginning in the second half of 2021.

“These proprietary blood biomarkers have the potential to significantly expand the utility of the KidneyIntelX platform, particularly in understanding how to efficiently enroll and characterize appropriate participants in new drug validation trials. We believe they could also contribute to a better understanding of patient response to approved drug therapies,” said Fergus Fleming, Chief Technology Officer, RenalytixAI. “We look forward to working with Joslin and other research and pharma collaborators to build a platform to advance our understanding of underlying causal pathways of kidney disease, and bring precision medicine solutions to clinical practice.”

In 2018, RenalytixAI secured an exclusive license from Joslin Diabetes Center to intellectual property relating to sTNFR1 and sTNFR2, both of which have been extensively validated as highly prognostic biomarkers in multiple settings and are integral to the KidneyIntelX test.

“We are pleased to extend our collaboration with RenalytixAI and advance our shared objective to translate high-quality research findings into clinical practice, thereby improving care and outcomes for people with kidney disease worldwide,” said Roberta Herman, MD, president and CEO of Joslin Diabetes Center.

The biomarker discoveries have been developed in the laboratory of Andrzej Krolewski, MD, PhD, former Section Head, now Senior Investigator, Genetics and Epidemiology at Joslin Diabetes Center and Professor of Medicine, Harvard Medical School, along with his research team at Joslin, as well as other collaborators. Dr. Krolewski and his team have been at the forefront of biomarker research in diabetic kidney disease and have contributed to some of the most important findings in this area over the past 20 years, including the intellectual property on RenalytixAI’s existing licensed biomarkers, sTNFR1 and sTNFR2 in Diabetic Kidney Disease. Biomarkers include additional inflammatory and pro-fibrotic markers which have been shown to improve prognostic performance in identifying which patients will progress to kidney failure, and predict responses to therapy.

About 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, or 37 million people, currently have chronic kidney disease (CKD). 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.2 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.
