Update on Finalization of MCIT Rule

to Provide National Medicare Coverage for FDA Breakthrough Devices and Diagnostics

NEW YORK, March 15, 2021 - Renalytix AI plc (LSE: RENX) (NASDAQ: RNLX), an artificial intelligence-enabled in vitro diagnostics company, focused on optimizing clinical management of kidney disease to drive improved patient outcomes and advance value-based care, provides an update on the establishment of the Medicare Coverage of Innovative Technology (MCIT) pathway to provide a coverage pathway for Medicare beneficiaries nationwide for innovative medical devices and diagnostic tests designated under the Breakthrough Device review program and with market authorization by the U.S. Food and Drug Administration (FDA).

Centers for Medicare & Medicaid Services (CMS) will delay the implementation date of the MCIT rule by 60 days, beginning a 30-day comment period to solicit additional public feedback on the rule. RenalytixAI expects the MCIT rule, as is or amended, will become effective within the expected 2021 FDA review and clearance period for KidneyIntelX and will have no material effect on the RenalytixAI business plan. 

RenalytixAI's lead product, KidneyIntelX, was granted FDA breakthrough designation in May 2019 and submitted its final FDA application in August 2020. The MCIT rule has bipartisan support in Congress and is considered by many as a key program to drive medical innovation and improve countless lives. Further background and details are contained in the Company's announcement on January 13, 2021.

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 1 out of 2 people with very low kidney function who are not on dialysis do not know they have CKD*. 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.
