Safety and Efficacy of Finerenone in Metabolic Dysfunction Associated Steatotic Liver Disease(MASLD/NAFLD) Related Cirrhosis Patients With Ascites in Prevention of Chronic Kidney Disease.

Renal dysfunction is a frequent and clinically important complication in cirrhosis, and MASLD/NAFLD is associated with increased risk of incident CKD; however, finerenone has not been specifically studied in MASLD-cirrhosis populations despite proven cardiorenal benefits in diabetic CKD. This monocentric, open-label, randomized controlled trial at the Department of Hepatology, ILBS, New Delhi will enroll 160 adults (18-80 years) with MASLD/NAFLD cirrhosis, clinical grade I-II ascites, and stable eGFR ≥60 mL/min/1.73 m² (MDRD-6), with key exclusions including CTP class C, refractory ascites, significant coagulopathy, intrinsic kidney disease, recent major cardiovascular events, and other protocol-defined contraindications. Participants will receive standard medical treatment (dietary measures, diuretics as indicated, metabolic control, complication management, albumin/beta-blockers as needed) and will be randomized to finerenone (5 mg/day uptitrated to 10-20 mg/day) versus spironolactone (50 mg/day uptitrated to 100-200 mg/day). The primary endpoint is incident CKD at 6 months , defined as sustained eGFR <60 mL/min/1.73 m² over 3 months. Secondary endpoints include MAKE/MACE/MALO at 6 months, drug-related adverse events (including hyperkalemia, hyponatremia, hypotension, hyperuricemia), AKI/AKD episodes, renal biomarkers (e.g., cystatin C, UPCR), ascites response, liver severity scores (MELD 3.0/MELD-Na/CTP), and metabolic/inflammatory/endothelial markers (e.g., HbA1c, HOMA-IR, hsCRP, vWF). Sample size (n=160; 80/arm) is powered to detect an absolute 20% reduction in CKD progression (35% to 15%) with 80% power and 5% alpha (10% dropout), with intention-to-treat analyses including Kaplan-Meier and Cox regression methods.
