ABSTRACT

BACKGROUND: Asians bear a heavier burden of chronic kidney disease (CKD), a common comorbidity of type 2 diabetes mellitus (T2DM), than non-Asians. Nonsteroidal mineralocorticoid receptor antagonists (MRAs) have garnered attention for their potential advantages in renal outcomes. Nevertheless, the impact on diverse ethnic groups remains unknown. METHODS: The PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database, and clinical trial registries were searched through August 2023 with the following keywords: nonsteroidal MRAs (finerenone, apararenone, esaxerenone, AZD9977, KBP-5074), CKD, T2DM, and randomized controlled trial (RCT). A random effects model was used to calculate overall effect sizes. RESULTS: Seven RCTs with 14 997 participants were enrolled. Nonsteroidal MRAs reduced urinary albumin to creatinine ratio (UACR) significantly more in Asians than non-Asians: (weighted mean difference [WMD], -0.59, 95% CI, -0.73 to -0.45, p < .01) vs (WMD, -0.29, 95% CI, -0.32 to -0.27, p < .01), respectively. The average decline of estimated glomerular filtration rate (eGFR) was similar in Asians and non-Asians (p > .05). Regarding systolic blood pressure (SBP), nonsteroidal MRAs had a better antihypertension performance in Asians (WMD, -5.12, 95% CI, -5.84 to -4.41, p < .01) compared to non-Asians (WMD, -3.64, 95% CI, -4.38 to -2.89, p < .01). A higher incidence of hyperkalemia and eGFR decrease ≥30% was found in Asians than non-Asians (p < .01). CONCLUSIONS: Nonsteroidal MRAs exhibited significant renal benefits by decreasing UACR and lowering SBP in Asian than that of non-Asian patients with CKD and T2DM, without increase of adverse events except hyperkalemia and eGFR decrease ≥30%.

ABSTRACT

INTRODUCTION: Several randomized controlled trials (RCTs) have examined mineralocorticoid receptor antagonists (MRAs) in heart failure (HF) with reduced ejection fraction (HFrEF). This systematic review and network meta-analysis (NMA) evaluated the comparative efficacy and safety of MRAs in HFrEF. MATERIALS AND METHODS: MEDLINE(Pubmed), Scopus, Cochrane and ClinicalTrials.gov were searched until April 8, 2024 for RCTs examining the efficacy and/or safety of MRAs in HFrEF. Double-independent study selection, extraction and quality assessment were performed. Random-effects frequentist NMA models were used. Evidence certainty was assessed via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Totally, 32 RCTs (15685 patients) were analyzed. Eplerenone ranked above spironolactone in all-cause mortality (hazard ratio {HR}=0.78, 95% confidence interval {CI} [0.66,0.91], GRADE:"Moderate"), cardiovascular death (HR=0.74, 95%CI [0.53, 1.04], GRADE:"Low") and in all safety outcomes. Spironolactone was superior to eplerenone in the composite of cardiovascular death or hospitalization (HR=0.67, 95%CI [0.50,0.89], GRADE:"Moderate"), HF hospitalization (HR=0.61, 95%CI [0.43,0.86], GRADE:"Moderate"), all-cause hospitalization (HR=0.51, 95%CI [0.26,0.98], GRADE:"Moderate") and cardiovascular hospitalization (HR=0.56, 95%CI [0.37,0.84], GRADE:"Moderate"). Canrenone ranked first in all-cause mortality, the composite outcome and HF hospitalization. Finerenone ranked first in hyperkalemia (risk ratio [RR]=1.56, 95%CI [0.89,2.74], GRADE:"Moderate"), renal injury (RR=0.56, 95%CI [0.24,1.29]), any adverse event (RR=0.84, 95%CI [0.75,0.94], GRADE:"Moderate"), treatment discontinuation (RR=0.89, 95%CI [0.64,1.23]) and hypotension (RR=1.06, 95%CI [0.12,9.41]). CONCLUSIONS: MRAs are effective in HFrEF with certain safety disparities. Spironolactone and eplerenone exhibited similar efficacy, however, eplerenone demonstrated superior safety. Finerenone was the safest MRA, while canrenone exhibited considerable efficacy, nonetheless, evidence for these MRAs were scarce.

ABSTRACT

BACKGROUND: According to the Centers for Disease Control and Prevention (CDC), diabetes affects approximately 37.3 million individuals in the USA, with another estimated 96 million people having a prediabetic state. Furthermore, one or two out of three adult Americans exhibit metabolic syndrome or an insulin-resistant state, depending on their age group. SUMMARY: Chronic kidney disease (CKD) represents a complication often associated with type II diabetes or the insulin-resistant condition, typically identifiable through proteinuria. Proteinuria serves as both a marker and a contributing factor to kidney damage, and it significantly heightens the risk of cardiovascular (CV) events, including atherosclerosis, heart attacks, and strokes. Renin-angiotensin-aldosterone system inhibitors (RAASis) have demonstrated clinical efficacy in lowering blood pressure, reducing proteinuria, and slowing CKD progression. However, hyperkalemia is a common and serious adverse effect associated with using RAASi. KEY MESSAGES: It is imperative to establish personalized management strategies to enable patients to continue RAASi therapy while effectively addressing hyperkalemia risk. Healthcare professionals must be careful not to inadvertently create a low renal perfusion state, which can reduce distal nephron luminal flow or luminal sodium concentration while using RAASi. Nonsteroidal mineralocorticoid receptor antagonists (nsMRAs), such as finerenone, are demonstrated to delay CKD progression and reduce CV complications, all while mitigating the risk of hyperkalemia. Additionally, maintaining a routine monitoring regimen for serum potassium levels among at-risk patients, making dietary adjustments, and considering the adoption of newer potassium-binding agents hold promise for optimizing RAASi therapy and achieving more effective hyperkalemia management.

ABSTRACT

INTRODUCTION: Proteinuria is a modifiable risk factor for chronic kidney disease (CKD) progression in children. Finerenone, a selective, non-steroidal, mineralocorticoid receptor antagonist (MRA) has been approved to treat adults with CKD associated with type 2 diabetes mellitus (T2DM) following results from the phase III clinical trials FIDELIO-DKD (NCT02540993) and FIGARO-DKD (NCT02545049). In a pre-specified pooled analysis of both studies (N = 13,026), finerenone was shown to have an acceptable safety profile and was efficacious in decreasing the risk of adverse kidney and cardiovascular outcomes and of proteinuria. OBJECTIVE: FIONA and the associated open-label extension (OLE) study aim to demonstrate that combining finerenone with an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) is safe, well-tolerated, and effective in sustainably reducing urinary protein excretion in children with CKD and proteinuria. DESIGN: FIONA (NCT05196035; Eudra-CT: 2021-002071-19) is a randomized (2:1), double-blind, placebo-controlled, multicenter, phase III study of 6 months' duration in approximately 219 pediatric patients. Patients must have a clinical diagnosis of CKD (an eGFR ≥ 30 mL/min/1.73 m2 if ≥ 1 to < 18 years or a serum creatinine level ≤ 0.40 mg/dL for infants 6 months to < 1 year) with significant proteinuria despite ACEi or ARB usage. The primary objective is to demonstrate that finerenone, added to an ACEi or ARB, is superior to placebo in reducing urinary protein excretion. FIONA OLE (NCT05457283; Eudra-CT: 2021-002905-89) is a single-arm, open-label study, enrolling participants who have completed FIONA. The primary objective of FIONA OLE is to provide long-term safety data. FIONA has two primary endpoints: urinary protein-to-creatinine ratio (UPCR) reduction of ≥ 30% from baseline to day 180 and percent change in UPCR from baseline to day 180. A sample size of 198 participants (aged 2 to < 18 years) in FIONA will provide at least 80% power to reject the null hypothesis of either of the two primary endpoints. CONCLUSION: FIONA is evaluating the use of finerenone in children with CKD and proteinuria. Should safety, tolerability, and efficacy be demonstrated, finerenone could become a useful additional therapeutic agent in managing proteinuria and improving kidney outcomes in children with CKD.

ABSTRACT

AIM: This Phase I study evaluated the safety and early efficacy of an aldosterone synthase inhibitor (BI 690517) in people with diabetes and albuminuric chronic kidney disease. METHODS: Double-blind, placebo-controlled study (NCT03165240) at 40 sites across Europe. Eligible participants [estimated glomerular filtration rate ≥20 and <75 ml/min/1.73 m2; urine albumin/creatinine ratio (UACR) ≥200 and <3500 mg/g] were randomized 6:1 to receive once-daily oral BI 690517 3, 10 or 40 mg, or eplerenone 25-50 mg, or placebo, for 28 days. The primary endpoint was the proportion of participants with drug-related adverse events (AEs). Secondary endpoints included changes from baseline in the UACR. RESULTS: Fifty-eight participants were randomized and treated from 27 November 2017 to 16 April 2020 (BI 690517: 3 mg, n = 18; 10 mg, n = 13; 40 mg, n = 14; eplerenone, n = 4; placebo, n = 9) for 28 days. Eight (13.8%) participants experienced drug-related AEs [BI 690517: 3 mg (two of 18); 10 mg (four of 13); 40 mg (two of 14)], most frequently constipation [10 mg (one of 13); 40 mg (one of 14)] and hyperkalaemia [3 mg (one of 18); 10 mg (one of 13)]. Most AEs were mild to moderate; one participant experienced severe hyperkalaemia (serum potassium 6.9 mmol/L; BI 690517 10 mg). UACR responses [≥20% decrease from baseline (first morning void urine) after 28 days] were observed for 80.0% receiving BI 690517 40 mg (eight of 10) versus 37.5% receiving placebo (three of eight). Aldosterone levels were suppressed by BI 690517, but not eplerenone or placebo. CONCLUSIONS: BI 690517 was generally well tolerated, reduced plasma aldosterone and may decrease albuminuria in participants with diabetes and albuminuric chronic kidney disease.

ABSTRACT

BACKGROUND: Esaxerenone is a novel non-steroidal mineralocorticoid receptor blocker. Here, we assessed efficacy and safety exposure-response relationships of esaxerenone and its covariates and thereby justified the recommended dosage regimens, focusing on the safety benefits of up-titration regimen in patients at higher risk for increased serum potassium (sK+). METHODS: The relationships between model-derived individual esaxerenone exposure and efficacy (blood pressure [BP]) and safety (increased sK+) were evaluated using multivariate linear regression and Cox regression analyses, respectively, using data from 1453 hypertensive patients with or without diabetic kidney disease in five clinical studies. RESULTS: Exposure-efficacy analyses demonstrated that higher exposure was linearly associated with greater BP reduction over the investigated dose range. Exposure-safety analyses showed that higher exposure was associated with a higher risk of increased sK+ under a fixed-dosing regimen; higher baseline sK+ and lower baseline estimated glomerular filtration rate (eGFR) were influential covariates. Model-based simulations suggested that fewer occurrences of increased sK+ are expected under the up-titration regimen (from 1.25 to 5 mg) relative to the fixed-dosing regimen (5 mg) in patients with different combinations of these covariates. CONCLUSIONS: The exposure-response analyses supported the esaxerenone recommended doses and the safety benefits of using the up-titration regimen.

ABSTRACT

Hypertension is the leading risk factor for premature death. The optimal treatment of low-renin hypertension (LRH), present in 30% of hypertensive individuals, is not known. LRH likely reflects a state of excess salt, expanded volume and/or mineralocorticoid receptor (MR) activation. Therefore, targeted treatment with MR antagonists (MRA) may be beneficial. The objective of this systematic review was to assess the efficacy of MRA therapy in LRH. MEDLINE, Embase and Cochrane databases were searched for randomised controlled trials of adults with LRH that compared the efficacy of MRA to placebo or other antihypertensive treatments. Risk of bias was assessed using the Cochrane risk of bias tool. A meta-analysis was performed using a random-effects model to estimate the difference in blood pressure and the certainty of evidence was assessed using the GRADE approach. The protocol is registered on PROSPERO (CRD42022318763). From the 1612 records identified, 17 studies met the inclusion criteria with a total sample size of 1043 participants. Seven studies (n = 345) were assessed as having a high risk of bias. Meta-analysis indicated that MRA reduced systolic blood pressure by -6.8 mmHg (95% confidence interval -9.6 to -4.1) and -4.8 mmHg (95% confidence interval -11.9 to 2.4) compared to angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARB) and diuretics. The certainty of the evidence was assessed as moderate and very low, respectively. The findings of this systematic review suggest that MRA is effective in lowering blood pressure in LRH and may be better than ACEi/ARB. Translation to clinical practice is limited by the uncertainty of evidence.

ABSTRACT

Chronic kidney disease (CKD) in patients with type 2 diabetes (T2D) is a major health challenge associated with a disproportionately high burden of end-stage renal disease, cardiovascular disease and death. This review summarizes the rationale, clinical evidence and practical implementation for non-steroidal mineralocorticoid receptor antagonists (nsMRAs), a drug class now approved and recommended for patients with T2D and CKD at risk of cardiorenal disease progression. Three nsMRAs (finerenone, esaxerenone and apararenone) have been evaluated but finerenone is currently the only approved nsMRA for this indication. Two large-scale, placebo-controlled, Phase 3 studies evaluated finerenone added to a maximally tolerated dose of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker. Over >2 years of treatment, finerenone was associated with a significant reduction in composite endpoints of renal and cardiovascular outcomes versus placebo. Esaxerenone or apararenone have both shown significant improvements in albuminuria versus placebo. In general, nsMRAs were well tolerated. Hyperkalaemia was the most notable treatment-related adverse event and could generally be managed through serum potassium monitoring and dose adjustments. The nsMRAs are now an important component of recommended treatment for CKD associated with T2D, providing a significant reduction in the risk of cardiorenal progression beyond what can be achieved with glucose and blood pressure control.

ABSTRACT

BACKGROUND: Mineralocorticoid receptor blockade could be a potential approach for the inhibition of chronic kidney disease (CKD) progression. The benefits and harms of different mineralocorticoid receptor antagonists (MRAs) in CKD are inconsistent. OBJECTIVES: The aim of the study was to summarize the benefits and harms of MRAs for CKD patients. METHODS: We searched MEDLINE, EMBASE, and the Cochrane databases for trials assessing the effects of MRAs on non-dialysis-dependent CKD populations. Treatment and adverse effects were summarized using meta-analysis. RESULTS: Fifty-three trials with 6 different MRAs involving 22,792 participants were included. Compared with the control group, MRAs reduced urinary albumin-to-creatinine ratio (weighted mean difference [WMD], -90.90 mg/g, 95% CI, -140.17 to -41.64 mg/g), 24-h urinary protein excretion (WMD, -0.20 g, 95% CI, -0.28 to -0.12 g), estimated glomerular filtration rate (eGFR) (WMD, -1.99 mL/min/1.73 m2, 95% CI, -3.28 to -0.70 mL/min/1.73 m2), chronic renal failure events (RR, 0.86, 95% CI, 0.79-0.93), and cardiovascular events (RR, 0.84, 95% CI, 0.77-0.92). MRAs increased the incidence of hyperkalemia (RR, 2.04, 95% CI, 1.73-2.40) and hypotension (RR, 1.80, 95% CI, 1.41-2.31). MRAs reduced the incidence of peripheral edema (RR, 0.65, 95% CI, 0.56-0.75) but not the risk of acute kidney injury (RR, 0.94, 95% CI, 0.79-1.13). Nonsteroidal MRAs (RR, 0.66, 95% CI, 0.57-0.75) but not steroidal MRAs (RR, 0.20, 95% CI, 0.02-1.68) significantly reduced the risk of peripheral edema. Steroidal MRAs (RR, 5.68, 95% CI, 1.26-25.67) but not nonsteroidal MRAs (RR, 0.52, 95% CI, 0.22-1.22) increased the risk of breast disorders. CONCLUSIONS: In the CKD patients, MRAs, particularly in combination with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, reduced albuminuria/proteinuria, eGFR, and the incidence of chronic renal failure, cardiovascular and peripheral edema events, whereas increasing the incidence of hyperkalemia and hypotension, without the augment of acute kidney injury events. Nonsteroidal MRAs were superior in the reduction of more albuminuria with fewer peripheral edema events and without the augment of breast disorder events.

ABSTRACT

BACKGROUND: Chronic kidney disease (CKD) poses a significant health risk in contemporary society. Current CKD treatments primarily involve renin-angiotensin-aldosterone system inhibitors and mineralocorticoid receptor antagonists, albeit associated with hyperkalemia risks. A novel selective mineralocorticoid receptor antagonist, finerenone, offers a promising, safer alternative for CKD therapy. This review comprehensively assesses the role and efficacy of finerenone in CKD treatment by analyzing clinical and animal studies. Emerging evidence consistently supports finerenone's ability to effectively slow the progression of CKD. By targeting the mineralocorticoid receptor, finerenone not only mitigates renal damage but also exhibits a favorable safety profile, minimizing hyperkalemia concerns. CONCLUSION: Finerenone emerges as a valuable addition to CKD therapy, demonstrating potential benefits in delaying CKD progression while minimizing side effects. Nevertheless, further clinical trials are necessary to provide a comprehensive understanding of its safety and efficacy.

ABSTRACT

Our prior study has suggested that percutaneous superselective adrenal arterial embolization (SAAE) with ethanol reduces blood pressure in patients with primary aldosteronism. This study aimed to compare the efficacy of SAAE with mineralocorticoid receptor antagonists (MRA) in treating patients with idiopathic hyperaldosteronism. In this prospective, randomized, controlled trial, we randomly assigned patients with idiopathic hyperaldosteronism in a 1:1 ratio to undergo SAAE (n = 29) or receive MRA (n = 30) treatment. The primary endpoint was the change in mean 24-hour ambulatory systolic blood pressure at 6 months. The secondary endpoints included changes in office blood pressure, home blood pressure, correction of aldosterone-to-renin ratio, and adverse events at 6 months. The mean change in 24-h ambulatory systolic blood pressure from baseline to 6-month follow-up was significantly different between the two groups (-8.4 mmHg; 95% confidence interval, -15.2 to -2.1 mmHg; P < 0.01). Office, home, and ambulatory blood pressure reduction at 6 months was more pronounced in the SAAE group than the MRA group (all P < 0.05). Aldosterone-to-renin ratio was lower in the SAAE group than the MRA group at 1 and 3 months (both P < 0.01), while it had no difference between the two groups at 6 months. None of the patients experienced serious adverse events in the perioperative and 6-month follow-up periods. SAAE, as a hormonal debulking procedure, is superior to MRA in blood pressure control and correction of biochemical abnormalities in patients with idiopathic hyperaldosteronism.

ABSTRACT

The overactivation of the mineralocorticoid receptor (MR) promotes pathophysiological processes related to multiple physiological systems, including the heart, vasculature, adipose tissue and kidneys. The inhibition of the MR with classical MR antagonists (MRA) has successfully improved outcomes most evidently in heart failure. However, real and perceived risk of side effects and limited tolerability associated with classical MRA have represented barriers to implementing MRA in settings where they have been already proven efficacious (heart failure with reduced ejection fraction) and studying their potential role in settings where they might be beneficial but where risk of safety events is perceived to be higher (renal disease). Novel non-steroidal MRA have distinct properties that might translate into favourable clinical effects and better safety profiles as compared with MRA currently used in clinical practice. Randomised trials have shown benefits of non-steroidal MRA in a range of clinical contexts, including diabetic kidney disease, hypertension and heart failure. This review provides an overview of the literature on the systemic impact of MR overactivation across organ systems. Moreover, we summarise the evidence from preclinical studies and clinical trials that have set the stage for a potential new paradigm of MR antagonism.

ABSTRACT

OBJECTIVES: Mineralocorticoid receptor antagonist (MRA) treatment is kidney protective but not recommended to patients with advanced renal failure due to the risk of hyperkalemia and death. This study aimed to examine the impact of MRA treatment in patients with chronic kidney disease on risk of hyperkalemia and subsequent mortality. METHODS: Rates of hyperkalemia were compared across strata of estimated glomerular filtration rate (eGFR) and MRA treatment based on cox regression using a nested case-control framework with 1 : 4 matching of patients with hyperkalemia (K + ≥6.0 mmol/l) with controls from the Danish general population on age, sex, diabetes, and hypertension. Risk of subsequent 30-day mortality was assessed in a cohort study with comparisons across strata of eGFR and MRA treatment based on multiple Cox regression. RESULTS: Thirty-two thousand four hundred twenty-six cases with hyperkalemia were matched with 127 038 controls. MRA treatment was associated with an increased rate of hyperkalemia with hazard ratios [95% confidence interval (95% CI)] of 8.28 (7.78-8.81), 5.12 (4.67-5.62), 3.58 (3.23-3.97), and 1.89 (1.60-2.23) in patients with eGFR at least 60, 45-59, 30-44, and less than 30 ml/min/1.73 m 2 , respectively (Reference: No MRA).However, MRA-exposed patients had a lower 30-day mortality risk following hyperkalemia with absolute risks (95% CI) of 29.3% (27.8-31.1), 20.3% (18.7-22.4), 19.5% (17.9-21.7), and 19.7% (17.4-22.5) compared to 39.8% (38.8-40.8), 32.0% (30.7-33.1), 28.8% (27.5-31.2), and 22.5% (21.4-23.4) in patients without MRA exposure in patients with GFR at least 60, 45-59, 30-44, and less than 30 ml/min/1.7 3m 2 , respectively. CONCLUSION: MRA treatment was associated with an increased rate of hyperkalemia but decreased risk of subsequent 30-day mortality across all stages of renal impairment.

ABSTRACT

BACKGROUND: Excess aldosterone accelerates chronic kidney disease progression. This phase 2 clinical trial assessed BI 690517, an aldosterone synthase inhibitor, for efficacy, safety, and dose selection. METHODS: This was a multinational, randomised, controlled, phase 2 trial. People aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 30 to less than 90 mL/min/1·73 m2, a urine albumin to creatinine ratio (UACR) of 200 to less than 5000 mg/g, and serum potassium of 4·8 mmol/L or less, taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, were enrolled. Participants were randomly assigned (1:1) to 8 weeks of empagliflozin or placebo run-in, followed by a second randomisation (1:1:1:1) to 14 weeks of treatment with once per day BI 690517 at doses of 3 mg, 10 mg, or 20 mg, or placebo. Study participants, research coordinators, investigators, and the data coordinating centre were masked to treatment assignment. The primary endpoint was the change in UACR measured in first morning void urine from baseline (second randomisation) to the end of treatment. This study is registered with ClinicalTrials.gov (NCT05182840) and is completed. FINDINGS: Between Feb 18 and Dec 30, 2022, of the 714 run-in participants, 586 were randomly assigned to receive BI 690517 or placebo. At baseline, 33% (n=196) were women, 67% (n=390) were men, 42% (n=244) had a racial identity other than White, and mean participant age was 63·8 years (SD 11·3). Mean baseline eGFR was 51·9 mL/min/1·73 m2 (17·7) and median UACR was 426 mg/g (IQR 205 to 889). Percentage change in first morning void UACR from baseline to the end of treatment at week 14 was -3% (95% CI -19 to 17) with placebo, -22% (-36 to -7) with BI 690517 3 mg, -39% (-50 to -26) with BI 690517 10 mg, and -37% (-49 to -22) with BI 690517 20 mg monotherapy. BI 690517 produced similar UACR reductions when added to empagliflozin. Investigator-reported hyperkalaemia occurred in 10% (14/146) of those in the BI 690517 3 mg group, 15% (22/144) in the BI 690517 10 mg group, and 18% (26/146) in the BI 690517 20 mg group, and in 6% (nine of 147) of those receiving placebo, with or without empagliflozin. Most participants with hyperkalaemia did not require intervention (86% [72/84]). Adrenal insufficiency was an adverse event of special interest reported in seven of 436 study participants (2%) receiving BI 690517 and one of 147 participants (1%) receiving matched placebo. No treatment-related deaths occurred during the study. INTERPRETATION: BI 690517 dose-dependently reduced albuminuria with concurrent renin-angiotensin system inhibition and empagliflozin, suggesting an additive efficacy for chronic kidney disease treatment without unexpected safety signals. FUNDING: Boehringer Ingelheim.

ABSTRACT

Finerenone, a new nonsteroidal mineralocorticoid receptor antagonist, showed a significant reduction in a primary composite renal outcome in FIDELIO-DKD and a significant reduction in a primary composite cardiovascular outcome in FIGARO-DKD in patients with type 2 diabetes (T2D) and a chronic kidney disease (CKD). In a subsequent analysis that combined these two clinical trials (FIDELITY), the reduction becomes statistically significant when compared to placebo for both outcomes, with a hazard ratio of 0.86 (95 % confidence interval 0.78-0.95; P = 0.0018) for the cardiovascular outcome and 0.77 (0.67-0.88; P = 0.0002) for the renal outcome. Furthermore, all renal events occurred less frequently with finerenone than with placebo, including the progression to end-stage CKD independently of the baseline levels of glomerular filtration rate and albuminuria and regardless of associated medications (including gliflozins). The safety profile was excellent. However, a significant increase in serum potassium level was observed. Even if it is less pronounced than the increase usually seen with spironolactone, the risk of hyperkalemia requires some caution regarding both patient selection and monitoring. Finerenone (Kerendia®) is indicated in the treatment of CKD with albuminuria in adult patients with T2D. In Belgium, it is reimbursed with conditions in combination with a renin-angiotensin blocker.


La finérénone, un nouvel antagoniste non stéroïdien du récepteur des minéralocorticoïdes, a montré, dans deux grandes études réalisées chez des patients avec un diabète de type 2 (DT2) et une maladie rénale chronique (MRC), une réduction significative du critère composite rénal dans FIDELIO-DKD et du critère composite cardiovasculaire dans FIGARO-DKD. Dans une analyse combinant les deux études (FIDELITY), la réduction est statistiquement significative dans le groupe finérénone par rapport au groupe placebo pour les deux critères, avec un hasard ratio de 0,86 (intervalle de confiance à 95 % 0,78-0,95; P = 0,0018) pour le critère cardiovasculaire et de 0,77 (0,67-0,88; P = 0,0002) pour le critère rénal. De plus, tous les événements rénaux surviennent moins fréquemment sous finérénone que sous placebo, y compris la progression vers l'insuffisance rénale terminale et ce, indépendamment du niveau du débit de filtration glomérulaire et de l'albuminurie à l'inclusion dans les essais ou des traitements associés (y compris les gliflozines). Le profil de sécurité est excellent, avec cependant une élévation de la kaliémie. Si elle est moindre que celle observée avec la spironolactone, elle nécessite néanmoins des précautions d'usage en termes de sélection des patients et de leur surveillance. La finérénone (Kerendia®) est indiquée dans le traitement de la MRC avec albuminurie chez le patient adulte avec DT2 et est remboursée en Belgique, sous conditions, en association avec un bloqueur du système rénine-angiotensine.

ABSTRACT

The renin-angiotensin-aldosterone system (RAAS) activation plays a key role in the chronic kidney disease (CKD) progression and in the cardiovascular complications (CVC) development in patients with diabetes mellitus (DM). RAAS blockers alone are not sufficient to prevent CVC and CVC progression. RAAS upregulation in CKD associated with DM triggers the mineralocorticoid receptors (MCR) hyperactivation which results in fibrosis and inflammation in the heart and kidneys. This review presents the current data about the variety of MCR hyperactivation manifestations, as well as about of multiplicity of MCR hyperactivation ways in DM. The efficacy and safety of finerenone, a new MCR nonsteroidal selective antagonist, are discussed.
