Doran Brings Significant Diagnostics Sector Experience to Lead the KidneyIntelX Global Sales Effort

LONDON and SALT LAKE CITY - September 07, 2023 - Renalytix plc (NASDAQ: RNLX) (LSE: RENX), the first company to commercialize an FDA approved artificial intelligence (AI) enabled prognostic blood test for individuals with type 2 diabetes and chronic kidney disease, announces the appointment of Howard Doran as Chief Business Officer, effective September 1, 2023. Mr. Doran's primary responsibility will be leading the KidneyIntelX global sales effort. He is a senior executive with over 30 years of diversified general management, strategic planning, and marketing/sales experience in the diagnostics and pharmaceutical industries in domestic and international markets.

Mr. Doran served as LipoScience, Inc's President and Chief Executive Officer until successful completion of LabCorp's acquisition of the company in November 2014. Preceding LipoScience, Mr. Doran was President and Chief Operating Officer of Constitution Medical, Inc., an early-stage in vitro diagnostics company and developer of the Bloodhound Fully Integrated Hematology System, which was acquired by Roche Diagnostics, Inc. in July 2013. Prior to Constitution Medical, Mr. Doran was a member of the senior executive team of Hologic, Inc. and served as President of Hologic's Global Diagnostics business. Mr. Doran joined the senior management team of Hologic in 2007 at the time of Hologic's acquisition of Cytyc Corporation, where he had been serving as Senior Vice President and Business Unit Director of Cytyc's $500 million in vitro diagnostics business. From 1997 through 2007, he was a key member of the management team of Cytyc Corporation during Cytyc's dramatic growth, serving in a number of senior commercial roles of increasing responsibility including physician sales and marketing, managed care initiatives and laboratory sales and marketing. Mr. Doran holds a Bachelor of Science degree in Management from West Chester University of Pennsylvania.

James McCullough, Chief Executive Officer of Renalytix, commented: "Howard brings significant experience to benefit Renalytix's sales and strategy at a time when KidneyIntelX has achieved necessary regulatory, outcomes data and reimbursement milestones to bring lifesaving prognosis to care delivery for the approximately 14 million Americans with type 2 diabetes and kidney disease. I am very excited to begin working with Howard closely this fall to achieve our business and patient service objectives."

"KidneyIntelX identifies patients at the highest risk of rapid progression of chronic kidney disease which opens the opportunity for earlier intervention to slow the advancement of this insidious disease.  Earlier intervention and treatment can dramatically alter the trajectory of unsustainable costs associated with this disease," said Howard Doran. "Having lost a family member to end stage kidney disease and another who was a kidney transplant recipient, this mission is personal to me. I look forward to helping guide this team's journey to maximize this opportunity."

About Chronic 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 37 million people⁴, 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.⁵ 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)¹, 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 disease⁶. Type 2 diabetes symptoms often develop over several years and approximately 23% of adults with Type 2 Diabetes are undiagnosed⁷. 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.

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 rapidly 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).
