bay-94-8862 and Hyperkalemia

Steroidal mineralocorticoid-receptor-antagonists (MRAs), such as spironolactone and eplerenone, are guideline-directed therapies in patients with heart failure with reduced ejection fraction or resistant hypertension. However, the associated risk of hyperkalemia and hormonal side effects limit their broad use and downstream cardiorenal protection in high-risk patients with type 2 diabetes mellitus (T2DM) and moderate-to-advanced chronic kidney disease (CKD). The critical unmet need to improve long-term cardiorenal outcomes in such patients with CKD has sparked considerable efforts to the discovery and development of a new class of compounds. Finerenone is a novel, nonsteroidal MRA that has recently received regulatory approval with the indication of cardiorenal protection in patients with CKD associated with T2DM. Two landmark phase 3 clinical trials, FIDELIO-DKD and FIGARO-DKD, demonstrated that among patients with T2DM and a broad spectrum of CKD, finerenone reduced the risk of "hard" cardiovascular and kidney failure outcomes as compared with placebo, with a minimal risk of hyperkalemia. Subgroup analyses of these trials also provided preliminary evidence that the efficacy and safety profile of finerenone was similar and irrespective of background therapy with other guideline-directed therapies, such as sodium-glucose co-transporter type 2 (SGLT-2) inhibitors and glucagone-like peptide 1 receptor agonists. Whether the combination of finerenone with a SGLT-2 inhibitor is more beneficial in patients with T2DM and CKD as compared with either therapy alone is a crucial research question that is currently under investigation in an ongoing clinical trial.

The phase III clinical trial of the nonsteroidal mineralocorticoid receptor antagonist finerenone (BAY 94-8862) has been completed, aiming to investigate renal and cardiovascular outcomes in type 2 diabetes (T2D) with chronic kidney disease (CKD). However, the efficacy and safety of finerenone in renal function remain controversial. The purpose of this study was to explore the efficacy and safety of finerenone in treating the patients with diabetic kidney disease (DKD).. Databases of PubMed, Cochrane Library, Embase, and Web of Science were searched for randomized controlled trials (RCTs) on patients with DKD receiving finerenone treatment from inception to September 2021. Data including patient characteristics and interested outcomes were extracted, and the dichotomous data and continuous variables were evaluated using risk ratio (RR) with 95% confidence intervals (CIs) and mean differences (MD) with 95% CIs, respectively.. A total of 4 RCTs involving 13,945 patients were included in this meta-analysis. Analysis results demonstrated that patients receiving finerenone showed a significant decrease in changing urinary albumin-to-creatinine ratio (UACR) from baseline (MD: -0.30; 95% CI [-0.33, -0.27], p = 0.46, I2 = 0%) (p < 0.05). The number of patients with ≥40% reduction in estimated glomerular filtration rate (eGFR) from baseline in the finerenone group was significantly smaller than that in the placebo group (RR: 0.85; 95% CI [0.78, 0.93], p = 0.60, I2 = 0%) (p < 0.05). No difference was found in adverse events between the finerenone and placebo groups (RR: 1.00; 95% CI [0.98, 1.01], p = 0.94, I2 = 0%) (p = 0.65). The incidence of hyperkalemia was higher in the finerenone group than that in the placebo group (RR: 2.03; 95% CI [1.83, 2.26], p = 0.95, I2 = 0%) (p < 0.05).. Finerenone contributes to the reduction of UACR and can ameliorate the deterioration of renal function in patients with T2D and CKD. The higher risk of hyperkalemia was found in the finerenone group compared with placebo; however, there was no difference in the risk of overall adverse events.

Clinical trials of the mineralocorticoid receptor antagonist (MRA) finerenone published recently suggest that they improve outcomes in patients with diabetic kidney disease (DKD). This review summarises key research from the last two years to provide clinicians with a synopsis of recent findings.. Large international trials, such as Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease (5674 participants) and Finerenone in Reducing Cardiovascular Mortality and Morbidity in Diabetic Kidney Disease (7437 participants), suggest that in proteinuric patients with DKD and estimated glomerular filtration rate >25 ml/min/1.73 m2, already on renin-angiotensin-aldosterone system inhibitors, addition of finerenone provided modest further improvement in composite renal and cardiovascular outcomes. Proteinuria was reduced; there was also a small drop in systolic blood pressure. Hyperkalaemia remained a concern, although the incidence is lower with finerenone. Emerging data suggest that newer potassium binding agents may mitigate this risk. Preclinical studies suggest additive benefits when MRA and sodium-glucose co-transporter 2 (SGLT-2) inhibitors are used in combination.. The nonsteroidal MRA finerenone could improve renal and cardiac outcomes further in diabetics with kidney disease when added to renin-angiotensin system inhibitors. Hyperkalaemia is probably less worrisome, but real-world data is needed. Combinations with other new nephroprotective agents (such as SGLT2i inhibitors) has the potential to provide increasing benefit. Benefits of finerenone in chronic kidney disease without diabetes remains to be seen.

Diabetic kidney disease (DKD) represents a leading cause of morbidity and mortality in subjects with diabetes and develops in more than one third of diabetic patients. Steroidal mineralocorticoid receptor antagonists (MRAs - eplerenone and spironolactone) reduce mortality in patients with heart failure with reduced ejection fraction (HFrEF). However, in clinical practice the use of steroidal MRAs is limited by the significant risk of hyperkalemia, especially in patients with impaired renal function. Finerenone, a novel nonsteroidal MRA, shows a higher selectivity and binding affinity for mineralocorticoid receptor (MR) compared to steroidal MRAs and has been shown to reduce chronic kidney disease (CKD) progression and cardiovascular mortality in patients with CKD and T2DM.. This review summarizes the current evidence on efficacy and safety of finerenone in the treatment of patients with CKD and T2DM, and discusses its mechanisms of action investigated in preclinical studies.. Pharmacological properties of finerenone and its unique tissue distribution are responsible for a lower risk of hyperkalemia. Therefore, finerenone represents a valuable therapeutic tool in patients with CKD/diabetic kidney disease (DKD). Recent studies have shown that finerenone delays the progression of CKD and reduce cardiovascular events in patients with DKD, highlighting its safety and efficacy in this high-risk population.

Finerenone is a novel non-steroidal mineralocorticoid antagonist (MRA) recently approved for the treatment of chronic kidney disease (CKD) in people with type 2 diabetes (T2D). We aim to conduct a systematic review of finerenone to know the efficacy and safety of finerenone in CKD with or without T2D.. A systematic search in the electronic database of PubMed and Google Scholar was made from inception until September 09, 2022, using several MeSH keywords related to finerenone. Ongoing trials were additionally searched from ClinicalTrials.Gov.. Five phase 2 and three phase 3, randomized, double-blind, placebo- or active-controlled studies of finerenone have been published to date and several other randomized and real-world studies of finerenone are currently undergoing.. In short-term studies in patients with CKD and reduced ejection heart failure, with or without T2D, finerenone 20 mg appears to have a better renal outcome compared with spironolactone and a better mortality outcome compared with eplerenone, with significantly lesser hyperkalemia compared to both spironolactone and finerenone. In long-term studies in patients with CKD and T2D, finerenone 10/20 mg significantly reduces the progression of renal disease and reduced CV endpoints (especially heart failure hospitalization) compared to placebo. Finerenone has no effect on HbA1c, body weight, and sexual side effects including gynecomastia, and has only a modest effect on blood pressure. However, hyperkalemia leading to drug withdrawal was significantly higher with finerenone compared to placebo. Safety data in real-world settings is a pressing priority.

The efficacy and safety of finerenone are unknown. Therefore, we performed this meta-analysis to investigate the efficacy and safety of finerenone in patients with chronic kidney disease (CKD).. We systematically searched for relevant studies in the PubMed, Embase and Cochrane Library databases from database inception until December 2020. We selected randomized controlled trials assessing finerenone treatment in patients with CKD.. Four trials (n=7,048) met the inclusion criteria. Compared with placebo, finerenone significantly reduced the urine albumin-to-creatinine ratio (UACR) in patients with CKD {mean difference (MD), -0.30 [95% confidence interval (CI), -0.50, -0.11], P<0.05}, and trial sequential analysis (TSA) confirmed this result. No significant difference was observed in eGFR in patients with CKD between the finerenone and placebo groups [MD, -0.90 (95% CI, -3.84 to 2.04), P>0.05]. Overall, the frequency of adverse events was similar in the two groups [relative risk (RR), 1. 00 (95% CI, 0.98, 1.02), P>0.05], and TSA confirmed this result. However, the finerenone group exhibited a lower risk of cardiovascular disorders and a higher risk of hyperkalemia than the placebo group [RR, 0.92 (95% CI, 0.85, 0.99), P<0.05 and RR, 2.04 (95% CI, 1.77, 2.34), P<0.00001, respectively].. This meta-analysis indicated that finerenone confers an important antiproteinuric effect on patients with CKD and reduces the risk of cardiovascular disorders in these patients. Finerenone may be a promising therapy option for patients with CKD.. PROSPERO registration number: CRD42021222404.

Treatment with angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) is used to reduce proteinuria and retard the progression of chronic kidney disease (CKD). However, resolution of proteinuria may be incomplete with these therapies and the addition of an aldosterone antagonist may be added to further prevent progression of CKD. This is an update of a Cochrane review first published in 2009 and updated in 2014.. To evaluate the effects of aldosterone antagonists (selective (eplerenone), non-selective (spironolactone or canrenone), or non-steroidal mineralocorticoid antagonists (finerenone)) in adults who have CKD with proteinuria (nephrotic and non-nephrotic range) on: patient-centred endpoints including kidney failure (previously know as end-stage kidney disease (ESKD)), major cardiovascular events, and death (any cause); kidney function (proteinuria, estimated glomerular filtration rate (eGFR), and doubling of serum creatinine); blood pressure; and adverse events (including hyperkalaemia, acute kidney injury, and gynaecomastia).. We searched the Cochrane Kidney and Transplant Register of Studies up to 13 January 2020 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov.. We included randomised controlled trials (RCTs) and quasi-RCTs that compared aldosterone antagonists in combination with ACEi or ARB (or both) to other anti-hypertensive strategies or placebo in participants with proteinuric CKD.. Two authors independently assessed study quality and extracted data. Data were summarised using random effects meta-analysis. We expressed summary treatment estimates as a risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, or standardised mean difference (SMD) when different scales were used together with their 95% confidence interval (CI). Risk of bias were assessed using the Cochrane tool. Evidence certainty was evaluated using GRADE.. Forty-four studies (5745 participants) were included. Risk of bias in the evaluated methodological domains were unclear or high risk in most studies. Adequate random sequence generation was present in 12 studies, allocation concealment in five studies, blinding of participant and investigators in 18 studies, blinding of outcome assessment in 15 studies, and complete outcome reporting in 24 studies. All studies comparing aldosterone antagonists to placebo or standard care were used in addition to an ACEi or ARB (or both). None of the studies were powered to detect differences in patient-level outcomes including kidney failure, major cardiovascular events or death. Aldosterone antagonists had uncertain effects on kidney failure (2 studies, 84 participants: RR 3.00, 95% CI 0.33 to 27.65, I² = 0%; very low certainty evidence), death (3 studies, 421 participants: RR 0.58, 95% CI 0.10 to 3.50, I² = 0%; low certainty evidence), and cardiovascular events (3 studies, 1067 participants: RR 0.95, 95% CI 0.26 to 3.56; I² = 42%; low certainty evidence) compared to placebo or standard care. Aldosterone antagonists may reduce protein excretion (14 studies, 1193 participants: SMD -0.51, 95% CI -0.82 to -0.20, I² = 82%; very low certainty evidence), eGFR (13 studies, 1165 participants, MD -3.00 mL/min/1.73 m², 95% CI -5.51 to -0.49, I² = 0%, low certainty evidence) and systolic blood pressure (14 studies, 911 participants: MD -4.98 mmHg, 95% CI -8.22 to -1.75, I² = 87%; very low certainty evidence) compared to placebo or standard care. Aldosterone antagonists probably increase the risk of hyperkalaemia (17 studies, 3001 participants: RR 2.17, 95% CI 1.47 to 3.22, I² = 0%; moderate certainty evidence), acute kidney injury (5 studies, 1446 participants: RR 2.04, 95% CI 1.05 to 3.97, I² = 0%; moderate certainty evidence), and gynaecomastia (4 studies, 281 participants: RR 5.14, 95% CI 1.14 to 23.23, I² = 0%; moderate certainty evidence) compared to placebo or standard care. Non-selective aldosterone antagonists plus ACEi or ARB had uncertain effects on protein excretion (2 studies, 139 participants: SMD -1.59, 95% CI -3.80 to 0.62, I² = 93%; very low certainty evidence) but may increase serum potassium (2 studies, 121 participants: MD 0.31 mEq/L, 95% CI 0.17 to 0.45, I² = 0%; low certainty evidence) compared to diuretics plus ACEi or ARB. Selective aldosterone antagonists may increase the risk of hyperkalaemia (2 studies, 500 participants: RR 1.62, 95% CI 0.66 to 3.95, I² =. The effects of aldosterone antagonists when added to ACEi or ARB (or both) on the risks of death, major cardiovascular events, and kidney failure in people with proteinuric CKD are uncertain. Aldosterone antagonists may reduce proteinuria, eGFR, and systolic blood pressure in adults who have mild to moderate CKD but may increase the risk of hyperkalaemia, acute kidney injury and gynaecomastia when added to ACEi and/or ARB.

Type 2 diabetes (T2D) is associated with an increased risk of diabetic kidney disease (DKD), cardiovascular disease, and heart failure, in part through activation of the renin-angiotensin-aldosterone system (RAAS). Although recent cardiovascular outcome trials have identified newer therapeutic agents such as sodium-glucose cotransporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1)-receptor agonists that reduce the risk of these complications, patients still exhibit residual cardiorenal morbidity and mortality. Accordingly, the identification of pharmacological agents that attenuate micro- and macrovascular complications related to T2D is a major priority. Our aim was to review evidence for the role of novel mineralocorticoid receptor antagonists (MRAs) that are being developed as adjunctive therapies to reduce the risk of DKD and cardiovascular disease in the setting of T2D.. Dual RAAS blockade with angiotensin-converting enzyme (ACE) inhibitor plus angiotensin receptor blockade (ARB) or ARB plus renin inhibition increases serious adverse events such as acute kidney injury and stroke. Due to the potential for these serious side effects, more recent interest has focused on newer, more selective non-steroidal MRAs such as finerenone as cardiorenal protective therapies. Finerenone reduces albuminuria in the setting of DKD in patients with T2D and has a lower risk of hyperkalemia compared to currently available MRAs. Novel MRAs such as finerenone have the potential to reduce the risk of DKD progression in patients with T2D. The impact of finerenone on hard, long-term cardiorenal endpoints is being examined in the FIGARO and FIDELIO trials in patients with DKD.

The efficacy and safety of mineralocorticoid receptor antagonists (MRAs) in patients with heart failure (HF) are controversial. To explore the role of MRAs in HF patients with an ejection fraction of no more than 45%, we conducted a network meta-analysis of randomized controlled trials (RCTs). We systematically searched PubMed, Embase, the Cochrane Library, and Clinicaltrials. RCTs involving the efficacy and/or safety of the use of MRAs in patients with HF were included. Outputs are presented as the surface under the cumulative ranking area (SUCRA) probabilities. Thirteen RCTs involving a total of 13,597 participants were included. Finerenone 10 mg was associated with the lowest probability of achieving at cardiovascular mortality (SUCRA, 5.0%), followed by finerenone 7.5 mg (SUCRA, 31.6%). In reducing N-terminal pro-B-type natriuretic peptide, finerenone 15 mg and finerenone 7.5 mg ranked the best and second best (SUCRA 68.1% and 63.8%, respectively), followed by finerenone 10 mg (SUCRA 59.2%). Spironolactone and canrenone have a higher risk of hyperkalemia and renal deterioration. Regarding the prevention of worsening renal function, finerenone 7.5 mg (SUCRA 14.3%) was the best treatment, followed by finerenone 2.5 mg (SUCRA 16.3%) and finerenone 10 mg (SUCRA 25.6%). Compared with spironolactone and eplerenone, finerenone 10 mg was associated with low risk in the occurrence of cardiovascular mortality, hospitalization, and adverse events (P < 0.01). This network meta-analysis is the first to find that finerenone 7.5-10 mg has the highest probability of being the optimal alternative among MRAs in the treatment of HF patients with an ejection fraction of no more than 45%.

There have been few major breakthroughs in heart failure (HF) drug therapies in recent years yet HF morbidity and mortality remain high, and there is a clear need for further research. Several newer agents that appear promising in Phase I and II trials do not progress to show clinical benefit in later trials. Part of the failure to find new therapies may lie in flawed trial design compounded by the need for ever-increasing patient numbers in order to prove outcome benefit. We summarize some of the most recent and promising medical therapies for HF.

Aldosterone binds to the mineralocorticoid receptor and has an important regulatory role in body fluid and electrolyte balance. It also influences a variety of different cell functions such as oxidative stress, inflammation and organ fibrosis. The important role of the tissue-specific mineralocorticoid receptors in cardiovascular and renal injury has been shown in knockout animals and in clinical studies Mineralocorticoid receptor antagonists seem to exert their beneficial effects via anti-oxidative, anti-inflammatory and anti-fibrotic effects. Spironolactone and eplerenone were the first steroidal mineralocorticoid receptor antagonist. The established steroidal mineralocorticoid receptor antagonists show important therapeutic effects but are hampered by a variety of side effects, most importantly clinically significant hyperkaliemia. Selective non-steroidal mineralocorticoid receptor antagonists have been recently developed and demonstrate effectiveness in early clinical trials. Finereroneholds promise for the future application of this new mineralocorticoid receptor antagonist class in patients with chronic kidney disease since it has shown a significant reduction in UACR combined with a safety profile similar to that in the placebo group. However, further long-term studies investigating relevant clinical end points like reduction in cardiovascular or renal event rate are warranted.

Finerenone reduced risk of cardiorenal outcomes in patients with CKD and type 2 diabetes in the FIDELIO-DKD trial. We report incidences and risk factors for hyperkalemia with finerenone and placebo in FIDELIO-DKD.. Over 2.6 years' median follow-up, 597 of 2785 (21.4%) and 256 of 2775 (9.2%) patients treated with finerenone and placebo, respectively, experienced treatment-emergent ≥mild hyperkalemia; 126 of 2802 (4.5%) and 38 of 2796 (1.4%) patients, respectively, experienced moderate hyperkalemia. Independent risk factors for ≥mild hyperkalemia were higher serum potassium, lower eGFR, increased urine albumin-creatinine ratio, younger age, female sex,. Finerenone was independently associated with hyperkalemia. However, routine potassium monitoring and hyperkalemia management strategies employed in FIDELIO-DKD minimized the impact of hyperkalemia, providing a basis for clinical use of finerenone.

Finerenone is a nonsteroidal selective mineralocorticoid receptor antagonist (MRA) that demonstrated efficacy in delaying the progression of chronic kidney disease (CKD) and reducing cardiovascular events in patients with CKD and type 2 diabetes mellitus in FIDELIO-DKD, where 5734 patients were randomized 1:1 to receive either finerenone or placebo, with a median follow-up of 2.6 years. Doses of finerenone 10 or 20 mg once daily were titrated based on (serum) potassium and estimated glomerular filtration rate. The MRA mode of action increases potassium.. Nonlinear mixed-effects population pharmacokinetic/pharmacodynamic models were used to analyze the finerenone dose-exposure-response relationship for potassium in FIDELIO-DKD. Individual time-varying exposures from pharmacokinetic analyses were related to the potassium response via a maximal effect, indirect-response model informed by 148,384 serum potassium measurements.. Although observed potassium levels decreased with increasing dose (i.e., inverse relation), model-based simulations for a fixed-dose setting (i.e., no dose titration) revealed the intrinsic finerenone dose-exposure-potassium response, with potassium levels increasing in a dose- and exposure-dependent manner, thus explaining the apparent conflict. The potassium limit for inclusion and uptitration from finerenone 10 to 20 mg in FIDELIO-DKD was ≤ 4.8 mmol/L. Modified limits of ≤ 5.0 mmol/L were simulated, resulting in higher hyperkalemia frequencies for both the finerenone and the placebo arms, whereas the relative hyperkalemia risk of a finerenone treatment compared with placebo did not increase.. The analyses demonstrated the effectiveness of finerenone dose titration in managing serum potassium and provide a quantitative basis to guide safe clinical use.

Finerenone, a nonsteroidal, selective mineralocorticoid receptor antagonist, reduced albuminuria in short-term trials involving patients with chronic kidney disease (CKD) and type 2 diabetes. However, its long-term effects on kidney and cardiovascular outcomes are unknown.. In this double-blind trial, we randomly assigned 5734 patients with CKD and type 2 diabetes in a 1:1 ratio to receive finerenone or placebo. Eligible patients had a urinary albumin-to-creatinine ratio (with albumin measured in milligrams and creatinine measured in grams) of 30 to less than 300, an estimated glomerular filtration rate (eGFR) of 25 to less than 60 ml per minute per 1.73 m. During a median follow-up of 2.6 years, a primary outcome event occurred in 504 of 2833 patients (17.8%) in the finerenone group and 600 of 2841 patients (21.1%) in the placebo group (hazard ratio, 0.82; 95% confidence interval [CI], 0.73 to 0.93; P = 0.001). A key secondary outcome event occurred in 367 patients (13.0%) and 420 patients (14.8%) in the respective groups (hazard ratio, 0.86; 95% CI, 0.75 to 0.99; P = 0.03). Overall, the frequency of adverse events was similar in the two groups. The incidence of hyperkalemia-related discontinuation of the trial regimen was higher with finerenone than with placebo (2.3% and 0.9%, respectively).. In patients with CKD and type 2 diabetes, treatment with finerenone resulted in lower risks of CKD progression and cardiovascular events than placebo.

Finerenone, a nonsteroidal mineralocorticoid receptor antagonist, was evaluated in Japanese patients with heart failure (HF) with reduced ejection fraction and chronic kidney disease and/or diabetes mellitus.. ARTS-HF Japan was a randomized, double-blind, phase 2b study. Patients (n=72) received oral, once-daily (o.d.) finerenone (2.5, 5, 7.5, 10 or 15 mg, up-titrated to 5, 10, 15, 20, or 20 mg, respectively, on day 30) or eplerenone (25 mg every other day, increased to 25 mg o.d. on day 30, and 50 mg on day 60) for 90 days. The primary endpoint was the proportion of individuals with a decrease of >30% in plasma NT-proBNP at day 90. Safety endpoints included the incidence of hyperkalemia. Decreases in NT-proBNP occurred in 23.1% of patients in the eplerenone group and 15.4%, 23.1%, 45.5%, 27.3% and 45.5% in the 2.5→5 mg, 5→10 mg, 7.5→15 mg, 10→20 mg and 15→20 mg finerenone groups, respectively (all P=NS). Mean changes in serum potassium levels were similar between groups.. Because of the small sample size, limited conclusions can be drawn. Considering the results of ARTS-HF and that finerenone was well tolerated in Japanese patients in ARTS-HF Japan, the safety and efficacy of finerenone should be further explored in a large outcomes trial including Japanese patients. (Circ J 2016; 80: 1113-1122).

Steroidal mineralocorticoid receptor antagonists, when added to a renin-angiotensin system blocker, further reduce proteinuria in patients with chronic kidney disease but may be underused because of a high risk of adverse events.. To evaluate the safety and efficacy of different oral doses of the nonsteroidal mineralocorticoid receptor antagonist finerenone, given for 90 days to patients with diabetes and high or very high albuminuria who are receiving an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker.. Randomized, double-blind, placebo-controlled, parallel-group study conducted at 148 sites in 23 countries. Patients were recruited from June 2013 to February 2014 and the study was completed in August 2014. Of 1501 screened patients, 823 were randomized and 821 received study drug.. Participants were randomly assigned to receive oral, once-daily finerenone (1.25 mg/d, n = 96; 2.5 mg/d, n = 92; 5 mg/d, n = 100; 7.5 mg/d, n = 97; 10 mg/d, n = 98; 15 mg/d, n = 125; and 25 mg/d, n = 119) or matching placebo (n = 94) for 90 days.. The primary outcome was the ratio of the urinary albumin-creatinine ratio (UACR) at day 90 vs at baseline. Safety end points were changes from baseline in serum potassium and estimated glomerular filtration rate.. The mean age of the participants was 64.2 years; 78% were male. At baseline, 36.7% of patients treated had very high albuminuria (UACR ≥300 mg/g) and 40.0% had an estimated glomerular filtration rate of 60 mL/min/1.73 m2 or lower. Finerenone demonstrated a dose-dependent reduction in UACR. The primary outcome, the placebo-corrected mean ratio of the UACR at day 90 relative to baseline, was reduced in the finerenone 7.5-, 10-, 15-, and 20-mg/d groups (for 7.5 mg/d, 0.79 [90% CI, 0.68-0.91; P = .004]; for 10 mg/d, 0.76 [90% CI, 0.65-0.88; P = .001]; for 15 mg/d, 0.67 [90% CI, 0.58-0.77; P<.001]; for 20 mg/d, 0.62 [90% CI, 0.54-0.72; P < .001]). The prespecified secondary outcome of hyperkalemia leading to discontinuation was not observed in the placebo and finerenone 10-mg/d groups; incidences in the finerenone 7.5-, 15-, and 20-mg/d groups were 2.1%, 3.2%, and 1.7%, respectively. There were no differences in the incidence of the prespecified secondary outcome of an estimated glomerular filtration rate decrease of 30% or more or in incidences of adverse events and serious adverse events between the placebo and finerenone groups.. Among patients with diabetic nephropathy, most receiving an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker, the addition of finerenone compared with placebo resulted in improvement in the urinary albumin-creatinine ratio. Further trials are needed to compare finerenone with other active medications.. clinicaltrials.gov Identifier: NCT1874431.
