LONDON and NEW YORK, 20 May 2025 - Renalytix plc (LSE: RENX) (OTCQB: RNLXY), a precision medicine company with lead testing service kidneyintelX.dkd, the only FDA-approved and Medicare reimbursed prognostic test to support early-stage risk assessment in chronic kidney disease, announces that a key milestone has been reached in the very first use of KidneyIntelX in a clinical trial, following the successful enrollment and treatment of the first patient to determine the safety and efficacy of a novel cell therapy for patients with Chronic Kidney Disease ("CKD").
