Introduction: Finerenone is a novel, selective, nonsteroidal mineralocorticoid receptor antagonist that significantly reduced the risk of kidney and CV outcomes in patients with CKD and T2D in the FIDELIO-DKD trial, with no effect on blood glucose. In advanced T2D, insulin is often used to control glycemia. This analysis will report outcomes from the FIDELIO-DKD trial by baseline insulin treatment.

Methods: In FIDELIO-DKD (NCT02540993), 5734 patients with T2D, UACR 30-5000 mg/g, eGFR 25-&lt;75 mL/min/1.73 m2 and treated with optimized RAS blockade were randomized to oral finerenone or placebo. The primary outcome was a composite of kidney failure, a sustained ≥40% eGFR decline from baseline, or renal death. The key secondary outcome was a composite of CV death, non-fatal MI, non-fatal stroke, or hospitalization for HF.

Results: Of the 5674 patients analyzed, 3637 (64.1%) were treated with insulin or insulin analogues at baseline. Patients treated with insulin at baseline had a higher A1C and a longer duration of diabetes, with higher proportions of statin and GLP-1RA use, and lower use of other anti-hyperglycemic agents than those who were not. Finerenone did not affect A1C during the trial. The primary and key secondary CV outcome occurred in fewer patients treated with finerenone, with no between-group interaction (primary outcome: HR 0.85, 95% CI 0.73-0.98 with insulin; HR 0.79, 95% CI 0.64-0.96 without insulin; P-value for interaction 0.56; CV outcome: HR 0.82, 95% CI 0.69-0.97 with insulin; HR 0.95, 95% CI 0.74-1.23 without insulin; P-value for interaction 0.33). Hyperkalemia events were similar between groups (mean treatment difference between finerenone and placebo for treatment-emergent serum potassium &gt;5.5 mmol/L, 11.1% with insulin and 13.4% without insulin), with a low incidence of hyperkalemia-related treatment discontinuation.

Conclusion: Finerenone has a beneficial effect on kidney and CV outcomes in patients with CKD and T2D, irrespective of insulin use at baseline.
