    Hypokalaemia in patients with type 2 diabetes and chronic kidney disease: the effect of finerenone-a FIDELITY analysis
    (Oxford University Press, 2025) Pitt, Bertram; Agarwal, Rajiv; Anker, Stefan D.; Rossing, Peter; Ruilope, Luis; Herzog, Charles A.; Greenberg, Barry; Pecoits-Filho, Roberto; Lambelet, Marc; Lawatscheck, Robert; Scalise, Andrea; Filippatos, Gerasimos; Medicine, School of Medicine
    Aims: Hypokalaemia is associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD). This exploratory FIDELITY analysis, a prespecified pooled patient-dataset from FIDELIO-DKD and FIGARO-DKD, investigated the incidence and effect of hypokalaemia in patients with CKD and type 2 diabetes (T2D) treated with finerenone vs. placebo. Methods and results: Outcomes include the incidence of treatment-emergent hypokalaemia (serum potassium <4.0 or <3.5 mmol/L) and the effect of finerenone on cardiovascular composite outcome (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or hospitalization for heart failure) and arrhythmia composite outcome (new diagnosis of atrial fibrillation/atrial flutter, hospitalization due to arrhythmia, or sudden cardiac death) by baseline serum potassium subgroups. In the FIDELITY population, treatment-emergent hypokalaemia with serum potassium <4.0 and <3.5 mmol/L occurred in 41.1% and 7.5%, respectively. Hazards of cardiovascular and arrhythmia composite outcomes were higher in patients with baseline serum potassium <4.0 vs. 4.0-4.5 mmol/L [hazard ratio (HR) 1.16; 95% confidence interval (CI) 1.02-1.32, P = 0.022 and HR 1.20; 95% CI 1.00-1.44, P = 0.055, respectively]. Finerenone reduced the incidence of hypokalaemia with serum potassium <4.0 mmol/L (HR 0.63; 95% CI 0.60-0.66) and <3.5 mmol/L (HR 0.46; 95% CI 0.40-0.53) vs. placebo. Finerenone lessened the hazard of cardiovascular and arrhythmia events vs. placebo, irrespective of baseline serum potassium. Conclusion: A substantial proportion of patients with CKD and T2D experienced hypokalaemia, which was associated with an increased hazard of adverse cardiovascular outcomes. Finerenone reduced the incidence of hypokalaemia. Finerenone reduced the hazard of cardiovascular and arrhythmia outcomes irrespective of serum potassium subgroups.

    Investigating new treatment opportunities for patients with chronic kidney disease in type 2 diabetes: the role of finerenone
    (Oxford University Press, 2022) Agarwal, Rajiv; Anker, Stefan D.; Bakris, George; Filippatos, Gerasimos; Pitt, Bertram; Rossing, Peter; Ruilope, Luis; Gebel, Martin; Kolkhof, Peter; Nowack, Christina; Joseph, Amer; Medicine, School of Medicine
    Despite the standard of care, patients with chronic kidney disease (CKD) and type 2 diabetes (T2D) progress to dialysis, are hospitalized for heart failure and die prematurely. Overactivation of the mineralocorticoid receptor (MR) causes inflammation and fibrosis that damages the kidney and heart. Finerenone, a nonsteroidal, selective MR antagonist, confers kidney and heart protection in both animal models and Phase II clinical studies; the effects on serum potassium and kidney function are minimal. Comprising the largest CKD outcomes program to date, FIDELIO-DKD (FInerenone in reducing kiDnEy faiLure and dIsease prOgression in Diabetic Kidney Disease) and FIGARO-DKD (FInerenone in reducinG cArdiovascular moRtality and mOrbidity in Diabetic Kidney Disease) are Phase III trials investigating the efficacy and safety of finerenone on kidney failure and cardiovascular outcomes from early to advanced CKD in T2D. By including echocardiograms and biomarkers, they extend our understanding of pathophysiology; by including quality of life measurements, they provide patient-centered outcomes; and by including understudied yet high-risk cardiorenal subpopulations, they have the potential to widen the scope of therapy in T2D with CKD.
