Finerenone and effects on mortality in chronic kidney disease and type 2 diabetes: a FIDELITY analysis.

ABSTRACT:

Aims

Finerenone reduces the risk of cardiovascular events in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). We investigated the causes of mortality in the FIDELITY population.

Methods and results

The FIDELITY prespecified pooled data analysis from FIDELIO-DKD and FIGARO-DKD excluded patients with heart failure and reduced ejection fraction. Outcomes included intention-to-treat and prespecified on-treatment analyses of the risk of all-cause and cardiovascular mortality. Of 13 026 patients [mean age, 64.8 years; mean estimated glomerular filtration rate (eGFR), 57.6 mL/min/1.73 m2], 99.8% were on renin-angiotensin system inhibitors. Finerenone reduced the incidence of all-cause and cardiovascular mortality vs. placebo (8.5% vs. 9.4% and 4.9% vs. 5.6%, respectively) and demonstrated significant on-treatment reductions [hazard ratio (HR), 0.82; 95% confidence interval (CI), 0.70-0.96; P = 0.014 and HR, 0.82; 95% CI, 0.67-0.99; P = 0.040, respectively]. Cardiovascular-related mortality was most common, and finerenone lowered the incidence of sudden cardiac death vs. placebo [1.3% (incidence rate 0.44/100 patient-years) vs. 1.8% (0.58/100 patient-years), respectively; HR, 0.75; 95% CI, 0.57-0.996; P = 0.046]. The effects of finerenone on mortality were similar across all Kidney Disease: Improving Global Outcomes risk groups. Event probability with finerenone at 4 years was consistent irrespective of baseline urine albumin-to-creatinine ratio, but seemingly more pronounced in patients with higher baseline eGFR.

Conclusion

In FIDELITY, finerenone significantly reduced the risk of all-cause and cardiovascular mortality vs. placebo in patients with T2D across a broad spectrum of CKD stages while on treatment, as well as sudden cardiac death in the intention-to-treat population.

Project description:BackgroundAnemia is common in patients with chronic kidney disease and type 2 diabetes. Finerenone improved heart and kidney outcomes in patients with chronic kidney disease and type 2 diabetes in FIDELITY.ObjectivesThis post hoc analysis investigated the efficacy and safety of finerenone vs placebo by baseline anemia status.MethodsAnemia was defined as serum hemoglobin levels <13 g/dL (male) or <12 g/dL (female) or treatment with an erythropoiesis-stimulating agent at baseline. Outcomes included cardiovascular (CV) and kidney composites, hospitalization for heart failure, and all-cause mortality. Safety was assessed through treatment-emergent adverse events.ResultsOf 12,971 patients, 33% had anemia at baseline. Finerenone reduced the risk of the CV composite outcome to a greater extent in patients with vs without anemia (HR: 0.75 [95% CI: 0.65-0.88] vs HR: 0.93 [95% CI: 0.82-1.05]; P for interaction = 0.03). Finerenone reduced the risk of the kidney composite outcome vs placebo, with no heterogeneity between patients with vs without anemia (HR: 0.79 [95% CI: 0.65-0.95] and HR: 0.74 [95% CI: 0.60-0.91]; P for interaction = 0.77). The risk of hospitalization for heart failure and all-cause mortality was lower with finerenone vs placebo, irrespective of anemia status. Patients with anemia experienced higher incidence of treatment-emergent hyperkalemia vs those without.ConclusionsFinerenone demonstrated CV and kidney benefit in patients with and without anemia. The benefit of finerenone on CV outcomes was greater in patients with vs without anemia at baseline. Anemia is likely a marker for higher-risk patients who are more susceptible to the benefits of finerenone.

Project description:AimsThe complementary studies FIDELIO-DKD and FIGARO-DKD in patients with type 2 diabetes and chronic kidney disease (CKD) examined cardiovascular and kidney outcomes in different, overlapping stages of CKD. The purpose of the FIDELITY analysis was to perform an individual patient-level prespecified pooled efficacy and safety analysis across a broad spectrum of CKD to provide more robust estimates of safety and efficacy of finerenone compared with placebo.Methods and resultsFor this prespecified analysis, two phase III, multicentre, double-blind trials involving patients with CKD and type 2 diabetes, randomized 1:1 to finerenone or placebo, were combined. Main time-to-event efficacy outcomes were a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or hospitalization for heart failure, and a composite of kidney failure, a sustained ≥57% decrease in estimated glomerular filtration rate from baseline over ≥4 weeks, or renal death. Among 13 026 patients with a median follow-up of 3.0 years (interquartile range 2.3-3.8 years), the composite cardiovascular outcome occurred in 825 (12.7%) patients receiving finerenone and 939 (14.4%) receiving placebo [hazard ratio (HR), 0.86; 95% confidence interval (CI), 0.78-0.95; P = 0.0018]. The composite kidney outcome occurred in 360 (5.5%) patients receiving finerenone and 465 (7.1%) receiving placebo (HR, 0.77; 95% CI, 0.67-0.88; P = 0.0002). Overall safety outcomes were generally similar between treatment arms. Hyperkalaemia leading to permanent treatment discontinuation occurred more frequently in patients receiving finerenone (1.7%) than placebo (0.6%).ConclusionFinerenone reduced the risk of clinically important cardiovascular and kidney outcomes vs. placebo across the spectrum of CKD in patients with type 2 diabetes.Key questionDoes finerenone, a novel selective, nonsteroidal mineralocorticoid receptor antagonist, added to maximum tolerated renin-angiotensin system inhibition reduce cardiovascular disease and kidney disease progression over a broad range of chronic kidney disease in patients with type 2 diabetes?Key findingIn a prespecified, pooled individual-level analysis from two randomized trials, we found reductions both in cardiovascular events and kidney failure outcomes with finerenone. Because 40% of the patients had an estimated glomerular filtration rate of >60 mL/min/1.73m2 they were identified solely on the basis of albuminuria.Take home messageFinerenone reduces the risk of clinical cardiovascular outcomes and kidney disease progression in a broad range of patients with chronic kidney disease and type 2 diabetes. Screening for albuminuria to identify at-risk patients among patients with type 2 diabetes facilitates reduction of both cardiovascular and kidney disease burden.

Project description:AimsHypokalaemia 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 resultsOutcomes 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.ConclusionA 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.

Project description:BackgroundThe FIDELIO-DKD trial (Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease) evaluated the effect of the nonsteroidal, selective mineralocorticoid receptor antagonist finerenone on kidney and cardiovascular outcomes in patients with chronic kidney disease and type 2 diabetes with optimized renin-angiotensin system blockade. Compared with placebo, finerenone reduced the composite kidney and cardiovascular outcomes. We report the effect of finerenone on individual cardiovascular outcomes and in patients with and without history of atherosclerotic cardiovascular disease (CVD).MethodsThis randomized, double-blind, placebo-controlled trial included patients with type 2 diabetes and urine albumin-to-creatinine ratio 30 to 5000 mg/g and an estimated glomerular filtration rate ≥25 to <75 mL per min per 1.73 m2, treated with optimized renin-angiotensin system blockade. Patients with a history of heart failure with reduced ejection fraction were excluded. Patients were randomized 1:1 to receive finerenone or placebo. The composite cardiovascular outcome included time to cardiovascular death, myocardial infarction, stroke, or hospitalization for heart failure. Prespecified cardiovascular analyses included analyses of the components of this composite and outcomes according to CVD history at baseline.ResultsBetween September 2015 and June 2018, 13 911 patients were screened and 5674 were randomized; 45.9% of patients had CVD at baseline. Over a median follow-up of 2.6 years (interquartile range, 2.0-3.4 years), finerenone reduced the risk of the composite cardiovascular outcome compared with placebo (hazard ratio, 0.86 [95% CI, 0.75-0.99]; P=0.034), with no significant interaction between patients with and without CVD (hazard ratio, 0.85 [95% CI, 0.71-1.01] in patients with a history of CVD; hazard ratio, 0.86 [95% CI, 0.68-1.08] in patients without a history of CVD; P value for interaction, 0.85). The incidence of treatment-emergent adverse events was similar between treatment arms, with a low incidence of hyperkalemia-related permanent treatment discontinuation (2.3% with finerenone versus 0.8% with placebo in patients with CVD and 2.2% with finerenone versus 1.0% with placebo in patients without CVD).ConclusionsAmong patients with chronic kidney disease and type 2 diabetes, finerenone reduced incidence of the composite cardiovascular outcome, with no evidence of differences in treatment effect based on preexisting CVD status.
