Type 2 Diabetic Kidney Disease

This study employs a prospective, randomized, double-blind, parallel-controlled design, aiming to enroll adult participants with type 2 diabetic kidney disease (DKD) who meet the eligibility criteria. With an angiotensin receptor blocker (ARB) as the background therapy, all participants will be randomized in a 1:1:1:1 ratio into four treatment groups: Group 1 (G1): ARB + empagliflozin + finerenone placebo + mazdutide placebo; Group 2 (G2): ARB + empagliflozin + finerenone + mazdutide placebo; Group 3 (G3): ARB + empagliflozin + mazdutide + finerenone placebo; Group 4 (G4): ARB + empagliflozin + mazdutide + finerenone. The primary comparisons include G2 vs. G1, G3 vs. G1, G4 vs. G2, and G4 vs. G3, designed to evaluate the superiority of triple therapy over dual therapy, and quadruple therapy over triple therapy, in reducing the urine albumin-to-creatinine ratio (UACR).
