The FDA has approved the first nonsteroidal, third-generation, mineralocorticoid receptor antagonists to reduce risk of kidney and cardiovascular mortality and morbidity in patients with chronic kidney disease and type 2 diabetes. It received a priority review and fast-track designation.
INDICATIONS
Finerenone can be prescribed to lower the risk of sustained estimated glomerular filtration rate (eGFR) decline, cardiovascular death, non-fatal myocardial infarction, end-stage kidney disease, and hospitalization from heart failure in adults with chronic kidney disease associated with type 2 diabetes.1
DOSAGE
The recommended dose is 20 mg once daily if eGFR is > 60 mL/min/1.73m2 and 10 mg if eGFR is ≥ 25 mL/min/1.73m2 to < 60 mL/min/1.73m2.1 Withhold the dose if serum potassium is > 5.5 mEq/L. Serum potassium and eGFR should be measured before initiation of treatment and periodically during treatment.
POTENTIAL ADVANTAGES
Finerenone is a more selective antagonist vs. spironolactone and more potent than eplerenone.2 It is the only FDA-approved mineralocorticoid for chronic kidney disease. It produces no activity on androgen, estrogen, or glucocorticoid receptors while still lowering the risk of hyperkalemia.1-3
POTENTIAL DISADVANTAGES
The most common adverse reaction (vs. placebo) is hyperkalemia (18.3% vs. 8%).1 Finerenone is a substrate for CYP3A4; concomitant use with strong CYP3A4 inhibitors are contraindicated.1 Avoid concomitant use with grapefruit or grapefruit juice or strong or moderate CYP3A4 inducers.1
COMMENTS
The efficacy of finerenone was evaluated in a randomized, double-blind, placebo-controlled study in adults with chronic kidney disease associated with type 2 diabetes.1 The study population presented with a mean eGFR of 44 mL/min/1.73m2, median urine albumin-to-creatinine ratio of 852 mg/g, and 98.8% were treated with an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB). Approximately 46% presented with a history of atherosclerotic cardiovascular (CV) disease. Subjects were randomized to finerenone (n = 2,833) or placebo (n = 2,841) and were followed for a minimum of 2.6 years. Those designated as New York Heart Association class II to IV were excluded. The primary composite efficacy endpoint was sustained decline in eGFR of ≥ 40%, progression to kidney failure, or renal death. The secondary endpoint was a composite of CV death, non-fatal myocardial infarction, non-fatal stroke, or hospitalization for heart failure. Finerenone reduced the primary composite endpoint vs. placebo (17.8% vs. 21.1%; HR, 0.82; 95% CI, 0.73-0.93). This was driven by the decline in eGFR (HR, 0.81; 95% CI, 0.72-0.92). The secondary composite endpoint also was reduced (HR, 0.86; 95% CI, 0.75-0.99). None of the individual components reached statistical significance. The authors of a recently completed study assessed the efficacy and safety of finerenone vs. placebo for reducing clinically important CV and renal outcomes.4 The results are pending.
CLINICAL IMPLICATIONS
Type 2 diabetes is a primary cause of chronic kidney disease. Mineralocorticoid receptor overactivation in type 2 diabetes appears to be the main pathophysiology resulting in cardiorenal disease. Established first-line treatments to prevent chronic kidney disease are renin-angiotensin system inhibitors (ACEI and ARB). More recently, sodium-glucose cotransporter 2 inhibitors, particularly dapagliflozin, have provided robust clinical benefit in patients with or without diabetes or cardiovascular disease.5,6 Finerenone offers a potential alternative to spironolactone and eplerenone, with fewer side effects. Its ultimate role remains to be determined. The cost for a 30-day supply is $569.10.
