Finerenone in Heart Failure and Chronic Kidney Disease with Type 2 Diabetes: the FINE-HEART pooled analysis of cardiovascular, kidney, and mortality outcomes.

Cardiovascular-kidney-metabolic syndrome is an emerging entity that connects cardiovascular diseases, chronic kidney disease, and diabetes. The non-steroidal mineralocorticoid receptor antagonist, finerenone, has been studied in three prospective randomized clinical trials of patients with cardio-kidney-metabolic syndrome: FIDELIO-DKD, FIGARO-DKD, and FINEARTS-HF. In light of the strong epidemiological overlap and shared mechanistic drivers of clinical outcomes across cardio-kidney-metabolic syndrome, we summarize the efficacy and safety of finerenone on cardiovascular, kidney, and mortality outcomes in this prespecified participant-level pooled analysis. The three trials included 18,991 participants (mean age 67 ± 10 years; 35% women). During 2.9 years median follow-up, the primary outcome of cardiovascular death occurred in 421 (4.4%) assigned to finerenone and 471 (5.0%) assigned to placebo (HR 0.89; 95% CI 0.78-1.01; P = 0.076). Death from any cause occurred in 1,042 (11.0%) participants in the finerenone arm and 1,136 (12.0%) in the placebo arm (HR 0.91; 95% CI 0.84-0.99; P = 0.027). Finerenone further reduced the risk of HF hospitalization (HR 0.83; 95% CI 0.75-0.92; P < 0.001) and the composite kidney outcome (HR 0.80; 95% CI 0.72-0.90; P < 0.001). While this pooled analysis failed to demonstrate significant reductions in cardiovascular death, finerenone was associated with significantly lower deaths of any cause, cardiovascular events, and kidney outcomes.
