RNLX Renalytix PLC

Renalytix plc (NASDAQ: RNLX) (LSE: RENX) announces opening the commercial availability of kidneyintelX.dkd™ testing in Saudi Arabia, Bahrain, Qatar, Oman, Kuwait, and United Arab Emirates through a distribution agreement with Vector Pharma. Following the recent announcement of FDA marketing authorization for kidneyintelX.dkd, Renalytix will take advantage of select opportunities to expand testing services outside the US market with qualified distribution partners.

In the six markets of the Gulf Cooperation Council (GCC), the International Diabetes Federation (IDF) has reported high prevalence rates of diabetes, with more than 20% of the population being diabetic and more than 15% being pre-diabetic in most GCC countries. These are among the highest reported incidence rates for diabetes globally1. Chronic kidney disease (CKD) is a significant complication of type 2 diabetes (T2D) in this region. An estimated 58% of individuals with T2D develop CKD, which concurrently increases the risk of heart failure and myocardial infarction2.

The agreement with Vector Pharma brings established distribution and market access capabilities with a strong GCC footprint. Vector Pharma will initially focus on building awareness and driving adoption to achieve specified annual sales targets by territory with kidneyintelX.dkd.

"As in the United States, patient care for early-stage diabetes and kidney disease is in the hands of primary care clinicians,” said Tom McLain, President, Renalytix. “Traditional laboratory distributors do not call on primary care practices. Our partnership with Vector Pharma, a pharmaceutical distributor with proven access and contacts in primary care, will accelerate efforts to introduce kidneyintelX.dkd and expand test adoption."

Vector Pharma Chief Executive Officer, Patrick Jordan, commented: “When you consider the markets in the Middle East are experiencing high rates of T2D and CKD, diabetic kidney disease management has become a core tenet of many Ministries of Health in the GCC. Being able to introduce kidneyintelX.dkd™ to complement the current care protocols will not only benefit the management of individual patients, but it will also address significant objectives to improve chronic disease diagnosis and treatment for the healthcare ecosystem as a whole.”

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 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.
