Introduction: Finerenone reduced risk of cardiorenal outcomes in patients with CKD and T2D in the FIDELIO-DKD and FIGARO-DKD studies. In FIDELIO-DKD the effects of finerenone on kidney and CV outcomes were consistent irrespective of glucagon-like peptide-1 receptor agonist (GLP-1RA) use, but analyses were better powered to evaluate change in urine albumin-to-creatinine ratio (UACR) . Here, we extend these analyses to patients in both studies (FIDELITY analysis) , thus encompassing a larger population with broader inclusion criteria.
Methods: Patients with T2D and CKD (UACR ≥30-<300 mg/g and eGFR ≥25-≤90 mL/min/1.73 m2, or UACR ≥300-≤5000 mg/g and eGFR ≥25 mL/min/1.73 m2) , treated with optimized renin-angiotensin system blockade, were randomized to finerenone or placebo. The effects of finerenone on CV (CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure) and kidney (kidney failure, sustained ≥57% eGFR decline, or renal death) composite outcomes, and on UACR at month 4, were analyzed by GLP-1RA use.
Results: Of 13026 patients, 944 (7.2%) received GLP-1RAs at baseline. Results were consistent irrespective of GLP-1RA use at baseline for the CV composite outcome (hazard ratio [HR] 0.76; 95% CI 0.52-1.with GLP-1RA; HR 0.87, 95% CI 0.79-0.96 without GLP-1RA; p-interaction 0.63) , and the kidney composite outcome (HR 0.82; 95% CI 0.45-1.48 with GLP-1RA; HR 0.77, 95% CI 0.67-0.89 without GLP-1RA; p-interaction 0.79) . A greater reduction in UACR was observed with finerenone in patients taking GLP-1RA at baseline (placebo-corrected change -38% with GLP-1RA and -31% without GLP-1RA use; p-interaction 0.03) . Incidence of hyperkalemia was similarly increased with finerenone irrespective of GLP-1RA use at baseline.
Conclusion: The benefits of finerenone on composite CV and kidney outcomes in patients with CKD and T2D are not modified by GLP-1RA use at baseline, with an increased effect observed for UACR reduction, suggesting a different mechanism of reduction in albuminuria.
