RESUMO
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.

The burden of adverse cardiorenal outcomes among patients with the trifecta of diabetes, heart failure (HF) and chronic kidney disease (CKD) remains high. Steroidal mineralocorticoid receptor antagonists (MRAs) have been shown to improve clinical outcomes in patients with HF, however, there is significant underutilization of these agents, especially in patients with advanced CKD. Non-steroidal MRAs are an emerging therapeutic option for patients with diabetic kidney disease and are now guideline-supported in this population. Non-steroidal MRAs have a unique pharmacological profile distinct from their steroidal counterparts that retains the class-specific cardiorenal benefits but may help mitigate adverse effects, especially hyperkalaemia, in patients with CKD. In this review we summarize the current evidence on the use of non-steroidal MRAs for improving cardiorenal outcomes in patients with CKD and diabetes, as well as for combination use alongside other foundational medical therapies used in HF and CKD.

Mineralocorticoid receptor (MR) activation is involved in propagating kidney injury, inflammation, and fibrosis and in the progression of chronic kidney disease (CKD). Multiple clinical studies have defined the efficacy of MR antagonism in attenuating progressive kidney disease, and the US Food and Drug Administration recently approved the nonsteroidal mineralocorticoid receptor antagonist (MRA) finerenone for this indication. In this review, we consider the basic science and clinical applicability of MR antagonism. Because hyperkalemia constitutes a constraint to implementing evidence-based MR blockade, we review MRA-associated hyperkalemia in the context of finerenone and discuss evolving mitigation strategies to enhance the safety and efficacy of this treatment. Although the FIDELIO-DKD and FIGARO-DKD clinical trials focused solely on patients with type 2 diabetes mellitus, we propose that MR activation and the resulting inflammation and fibrosis act as a substantive pathogenetic mediator not only in people with diabetic CKD but also in those with CKD without diabetes. We close by briefly discussing both recently initiated and future clinical trials that focus on extending the attributes of MR antagonism to a wider array of nondiabetic kidney disorders, such as patients with nonalbuminuric CKD.

PURPOSE OF REVIEW: The study aims to verify the advantages of nonsteroidal mineralocorticoid receptor blockers (MRBs) in the management of hypertension and cardiovascular and renal diseases, comparing with conventional MRBs. RECENT FINDINGS: Based on the unique structures, the nonsteroidal MRBs have higher selectivity for mineralocorticoid receptors (MRs) and show no agonist activity for major steroid hormone receptors in contrast to steroidal MRBs. Today, there are two nonsteroidal MRBs, esaxerenone and finerenone, which completed phase 3 clinical trials. Series of clinical trials have shown that both agents achieve similar MR blockade with smaller doses as compared with steroidal MRBs, but have no off-target side effect such as gynecomastia. Esaxerenone has persistent blood pressure-lowering effects in various hypertensive populations, including essential hypertension and those with diabetes and/or chronic kidney disease, while finerenone has demonstrated reduction of the cardiovascular risk rather than blood pressure in patients with diabetes and chronic kidney disease. Nonsteroidal MRBs are a more refined agent which contributes to appropriate MR blocking with minimized unpleasant adverse effects.

PURPOSE: Esaxerenone is a novel, oral, nonsteroidal treatment for hypertension. Physiologically based pharmacokinetic (PBPK) modelling was performed to predict the drug-drug interaction (DDI) effect of cytochrome P450 (CYP)3A modulators on esaxerenone pharmacokinetics in healthy subjects and subjects with hepatic impairment. METHODS: In our PBPK model, the fraction of esaxerenone metabolised by CYP3A was estimated from mass-balance data and verified and optimised by clinical DDI study results with strong CYP3A modulators. The model was also verified by the observed pharmacokinetics after multiple oral dosing and by the effect of hepatic impairment on esaxerenone pharmacokinetics. The model was applied to predict the DDI effects on esaxerenone pharmacokinetics with untested CYP3A modulators in healthy subjects and with strong CYP3A modulators in subjects with hepatic impairment. RESULTS: The PBPK model well described esaxerenone pharmacokinetics after multiple oral dosing. The predicted fold changes in esaxerenone plasma exposure after coadministration with strong CYP3A modulators were comparable with the observed data (1.53-fold with itraconazole and 0.31-fold with rifampicin). Predicted DDIs with untested moderate CYP3A modulators were less than the observed DDI with strong CYP3A modulators. The PBPK model also described the effect of hepatic impairment on esaxerenone plasma exposure. The predicted DDI results with strong CYP3A modulators in subjects with hepatic impairment indicate that, for concomitant use of CYP3A modulators, caution is advised for subjects with hepatic impairment, as is for healthy subjects. CONCLUSION: The PBPK model developed predicted esaxerenone pharmacokinetics and DDIs and informed concurrent use of esaxerenone with CYP3A modulators.

Endothelial dysfunction contributes to cardiometabolic disorders, including hypertension, obesity, and type 2 diabetes. Esaxerenone is a selective, nonsteroidal, high-affinity mineralocorticoid receptor blocker recently approved in Japan for the treatment of hypertension. Although imbalanced signaling between vasorelaxant and vasocontractile factors induced by endothelial stimulation is often observed in type 2 diabetic vessels, the effects of esaxerenone on endothelium-dependent responses in type 2 diabetes remain unclear. The aim of this study was to investigate the effect of esaxerenone on endothelium-dependent responses in superior mesenteric arteries isolated from type 2 diabetic Goto-Kakizaki (GK) rats. It was found that esaxerenone (3 mg/kg/d for 4 weeks, per os (p.o.)) partially ameliorated acetylcholine (ACh)-induced endothelium-derived hyperpolarizing factor (EDHF)-type relaxation and NS309, a potent activator of small- and intermediate-conductance Ca2+-activated K+ channels, -induced relaxation, and reduced ACh-induced endothelium-derived contracting factor (EDCF)-mediated contraction. These results suggest that esaxerenone ameliorates endothelial function through increased EDHF signaling and suppressed EDCF signaling.

BACKGROUND: The nonsteroidal mineralocorticoid receptor blocker esaxerenone is effective in reducing blood pressure (BP). OBJECTIVE: In this study, we investigated esaxerenone-driven sodium homeostasis and its association with changes in BP in Dahl salt-sensitive (DSS) hypertensive rats. METHODS: In the different experimental setups, we evaluated BP by a radiotelemetry system, and sodium homeostasis was determined by an approach of sodium intake (food intake) and excretion (urinary excretion) in DSS rats with a low-salt diet (0.3% NaCl), high-salt diet (HSD, 8% NaCl), HSD plus 0.001% esaxerenone (w/w), and HSD plus 0.05% furosemide. RESULTS: HSD-fed DSS rats showed a dramatic increase in BP with a non-dipper pattern, while esaxerenone treatment, but not furosemide, significantly reduced BP with a dipper pattern. The cumulative sodium excretion in the active period was significantly elevated in esaxerenone- and furosemide-treated rats compared with their HSD-fed counterparts. Sodium content in the skin, skinned carcass, and total body tended to be lower in esaxerenone-treated rats than in their HSD-fed counterparts, while these values were unchanged in furosemide-treated rats. Consistently, sodium balance tended to be reduced in esaxerenone-treated rats during the active period. Histological evaluation showed that esaxerenone, but not furosemide, treatment attenuated glomerulosclerosis, tubulointerstitial fibrosis, and urinary protein excretion induced by high salt loading. CONCLUSIONS: Collectively, these findings suggest that an esaxerenone treatment-induced reduction in BP and renoprotection are associated with body sodium homeostasis in salt-loaded DSS rats.

During the recent 30 years, there has been a dramatic increase in knowledge about the role of aldosterone and the mineralocorticoid receptor (MR) in the pathophysiology of cardiovascular (CV) and kidney diseases. The scientific perspective on the aldosterone/MR ensemble extended from a previously renal epithelial-centered focus on sodium-potassium exchange to a broader view as systemic modulators of extracellular matrix, inflammation and fibrosis. Spironolactone was launched as the first antagonist of aldosterone 27 years before the MR was cloned. It was classified as a potassium-sparing diuretic, based on its initial clinical characterization as a diuretic and its preferred activity to compensate for the potassium loss induced by loop diuretics when used in combination. The second steroidal MR antagonist was eplerenone which was discovered at a time when the role of aldosterone and MR in cardiac fibrosis was rediscovered. The constraint of developing potentially life-threatening hyperkalaemia when used in combination with other inhibitors of the renin-angiotensin-system (RAS) in patients with reduced kidney function initiated extensive research and development activities with the goal to identify novel nonsteroidal MR antagonists with an improved benefit-risk ratio. Here we summarize major current clinical trials with MRAs in different CV and renal diseases. Addition of the nonsteroidal MRA finerenone to optimal RAS blockade recently reduced CV and kidney outcomes in two large phase III trials in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). We provide an outlook on further opportunities for combination therapy of nonsteroidal MRA finerenone with RAS inhibitors and sodium-glucose cotransporter-2 inhibitors (SGLT2i).

BACKGROUND: Esaxerenone has potential renoprotective effects and reduces the urinary albumin-to-creatinine ratio (UACR) in patients with diabetic kidney disease and overt nephropathy. We investigated the efficacy and safety of esaxerenone in Japanese patients with type 2 diabetes (T2D) and macroalbuminuria (UACR ≥ 300 mg/g creatinine). METHODS: We conducted a multicenter, single-arm, open-label phase III study in 56 patients with T2D and UACR ≥ 300 mg/g creatinine with estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m2 and treated with a renin-angiotensin system inhibitor. Patients received esaxerenone for 28 weeks at 1.25 mg/day initially with titration to 2.5 mg/day based on serum potassium (K+) monitoring. Efficacy was evaluated as the change in UACR from baseline to week 28. Safety endpoints included adverse events (AEs), incidence of serum K+ increase, and change in eGFR from baseline. RESULTS: UACR decreased by 54.6% (95% CI 46.9%, 61.3%) on average from baseline (544.1 mg/g creatinine) to the end of treatment (246.8 mg/g creatinine); 51.8% of patients showed improvement to early nephropathy. AE incidence was 69.6%. Three patients (5.4%) had serum K+ levels ≥ 6.0 mEq/L or ≥ 5.5 mEq/L on two consecutive occasions. Hyperkalemia in two patients was transient and resolved during the treatment period. One patient discontinued following two consecutive serum K+ values ≥ 5.5 mEq/L. The maximum change from baseline in eGFR was - 8.3 mL/min/1.73 m2 at week 24. CONCLUSIONS: Esaxerenone reduced UACR in Japanese patients with T2D and UACR ≥ 300 mg/g creatinine; more than half experienced a transition from UACR ≥ 300 mg/g creatinine to UACR < 300 mg/g creatinine.

We investigated the effects of esaxerenone, a novel, nonsteroidal, and selective mineralocorticoid receptor blocker, on cardiac function in Dahl salt-sensitive (DSS) rats. We provided 6-week-old DSS rats a high-salt diet (HSD, 8% NaCl). Following six weeks of HSD feeding (establishment of cardiac hypertrophy), we divided the animals into the following two groups: HSD or HSD + esaxerenone (0.001%, w/w). In survival study, all HSD-fed animals died by 24 weeks of age, whereas the esaxerenone-treated HSD-fed animals showed significantly improved survival. We used the same protocol with a separate set of animals to evaluate the cardiac function by echocardiography after four weeks of treatment. The results showed that HSD-fed animals developed cardiac dysfunction as evidenced by reduced stroke volume, ejection fraction, and cardiac output. Importantly, esaxerenone treatment decreased the worsening of cardiac dysfunction concomitant with a significantly reduced level of systolic blood pressure. In addition, treatment with esaxerenone in HSD-fed DSS rats caused a reduced level of cardiac remodeling as well as fibrosis. Furthermore, inflammation and oxidative stress were significantly reduced. These data indicate that esaxerenone has the potential to mitigate cardiac dysfunction in salt-induced myocardial injury in rats.

AIMS: To characterize the pharmacokinetics, pharmacodynamics and safety of esaxerenone, a mineralocorticoid receptor antagonist, in healthy adult Japanese men. METHODS: Double-blind, placebo-controlled, sequential, dose-escalation studies were conducted in subjects randomized to receive oral once-daily esaxerenone (ranges: 5-200 mg [single-dose]; 10-100 mg over 10 days [multiple-dose]) or placebo under fasting conditions. Plasma concentrations were analysed by liquid chromatograph-tandem mass spectrometry. Pharmacokinetic parameters were determined by noncompartment analysis. Plasma/urine levels of pharmacodynamic biomarkers for mineralocorticoid receptor activity were evaluated. RESULTS: In total, 48/48 and 39/40 subjects completed the single- and multiple-dose studies, respectively. Exposures were generally dose-proportional. The tmax , t1/2 and CL/F remained unchanged, independent of dose; the respective ranges were 1.5-4.0 h, 22.3-25.1 h, and 4.0-5.2 l h-1 (multiple-dose study). Vz /F ranged from 136.5 to 283.7 l in the multiple-dose study, and exposure reached steady state by day 4. The mean observed accumulation ratio, by dose, ranged from 1.36-1.98. The urinary Na+ /K+ ratio increased after single-dose administration; however, its relationship to the doses tested remains unclear. Plasma renin activity, active renin concentration and aldosterone concentration increased dose-dependently. Although blood potassium levels increased dose-dependently in the multiple-dose study (reaching a maximum mean ± standard deviation of 4.63 ± 0.354 mmol l-1 in the 100-mg group), no safety/tolerability-related problems were detected in either study. CONCLUSIONS: Exposure levels in healthy adults receiving esaxerenone were generally dose-proportional. Dose-dependent changes in plasma pharmacodynamic biomarkers for the mineralocorticoid receptor were identified during multiple-dose treatment and support the pharmacological activity of esaxerenone. No important safety concerns were identified.

The EXCITE-HT study aimed to evaluate the efficacy and safety of esaxerenone versus thiazide diuretics (trichlormethiazide) as second-line treatment for Japanese patients with uncontrolled essential hypertension. This was a 12-week, multicenter, randomized, open-label, parallel-group study. The non-inferiority of esaxerenone to trichlormethiazide was confirmed if the upper limit of the two-sided 95% confidence interval (CI) for the difference in systolic blood pressure (SBP)/diastolic blood pressure (DBP) change between groups was below 3.9/2.1 mmHg. A total of 295 and 290 patients were included in the esaxerenone and trichlormethiazide groups, respectively. The non-inferiority of esaxerenone to trichlormethiazide was demonstrated: least squares mean change differences in morning home SBP/DBP at end of treatment (EOT) were -2.2 (95% CI, -3.6, -0.8) mmHg for SBP/-0.6 (-1.4, 0.2) mmHg for DBP. Morning home, bedtime home, and office BP significantly decreased (all p < 0.001) from baseline to EOT in both groups. The urinary albumin-to-creatinine ratio and N-terminal pro-brain natriuretic peptide level decreased from baseline to Week 12 in both groups, with no notable intergroup difference. Serum potassium elevations occurred more frequently with esaxerenone, while serum potassium reductions occurred more with trichlormethiazide. Uric acid elevations were observed in both groups, but more frequently with trichlormethiazide than esaxerenone. No cases of gout occurred in this study. Reductions in estimated glomerular filtration rate were similarly observed in both groups. EXCITE-HT is the first randomized controlled study to demonstrate evidence that esaxerenone is non-inferior to trichlormethiazide as second-line treatment for Japanese patients with uncontrolled essential hypertension, with no new safety concerns. The EXCITE-HT study demonstrated the non-inferiority of esaxerenone to trichlormethiazide in its morning home blood pressure lowering effect and safety profile in Japanese patients with uncontrolled essential hypertension who were previously treated with an angiotensin II receptor blocker or calcium channel blocker.
RESUMO
This study aimed to identify factors associated with a strong home blood pressure (BP)-lowering effect of esaxerenone and the incidence of elevated serum potassium levels in hypertensive patients treated with esaxerenone. A pooled analysis of five multicenter, prospective, open-label single-arm studies was conducted, including 479 patients in the full analysis set (FAS) and 492 patients in the safety analysis set. Multivariate linear regression analysis of morning home systolic BP (SBP) and diastolic BP (DBP) changes from baseline to Week 12 in the FAS (primary endpoint) showed that male sex (estimated change 4.37 mmHg), office pulse rate ≥100 beats/min (25.10 mmHg), and calcium channel blocker (CCB) use as a basal antihypertensive agent (4.53 mmHg) were significantly associated with a positive estimated change (weaker BP-lowering effect) in morning home SBP. CCB use (3.70 mmHg) was associated with a positive estimated change in morning home DBP. Urine albumin-to-creatinine ratio 30 to <300 mg/gCr (-4.13 mmHg) was significantly associated with a negative estimated change (stronger BP-lowering effect) in morning home SBP. Based on multivariate logistic regression analysis, elevated baseline serum potassium level (≥4.5 vs < 4.5 mEq/L, odds ratio 13.502) was significantly associated with a high incidence of serum potassium level ≥5.5 mEq/L after esaxerenone treatment. In conclusion, factors associated with a strong BP-lowering effect of esaxerenone were female sex and use of renin-angiotensin system inhibitors as a basal antihypertensive drug. Patients with baseline serum potassium levels ≥4.5 mEq/L had an increased risk of developing elevated serum potassium levels (≥5.5 mEq/L) after esaxerenone treatment.
RESUMO
BACKGROUND: We examined whether the pharmacodynamic drug-drug interaction between esaxerenone and trimethoprim enhances the hyperkalemic effect. METHODS: A retrospective observational study was conducted to identify patients >18 years undertaking esaxerenone alone or esaxerenone plus trimethoprim at Mie University Hospital from May 2019 to December 2022. We performed propensity score-matching (1:1) to compare between-group differences in the maximum change in serum potassium levels (ΔK) using the Mann-Whitney U test. For esaxerenone plus trimethoprim, Spearman's correlation coefficients were used to examine correlations between ΔK and variables, including changes in blood urea nitrogen (ΔBUN), serum creatinine levels (ΔCr), and weekly trimethoprim cumulative dose. RESULTS: Out of propensity score-matched groups (n=8 each), serum potassium levels significantly increased after administration of esaxerenone alone (4.4 [4.2 to 4.7] meq/L to 5.2 [4.7 to 5.4] meq/L, p=0.008) and esaxerenone plus trimethoprim (4.2 [4.0 to 5.1] meq/L to 5.4 [4.7 to 5.5] meq/L, p=0.023). ΔK did not significantly differ between the groups (esaxerenone alone; 0.6 [0.3 to 0.9] meq/L vs. esaxerenone plus trimethoprim; 1.0 [0.4 to 1.3] meq/L, p=0.342). ΔK positively correlated with ΔBUN (r=0.988, p<0.001) or ΔCr (r=0.800, p=0.017). There was a trend of correlation of ΔK with a weekly cumulative trimethoprim dose (r=0.607, p=0.110). CONCLUSIONS: The hyperkalemic effect of the drug-drug interaction between esaxerenone and trimethoprim is not notable and related to renal function and trimethoprim dosage.
RESUMO
Adequate management of nocturnal hypertension is crucial to reduce the risk of organ damage and cardiovascular events. The EARLY-NH study was a prospective, open-label, multicenter study conducted in Japanese patients with nocturnal hypertension who received esaxerenone treatment for 12 weeks. This post hoc analysis aimed to assess (1) the relationship between changes in morning home systolic blood pressure (SBP), bedtime home SBP, and nighttime home SBP based on changes in SBP and achievement rates of target SBP levels; and (2) the correlation between nighttime home SBP measurements using brachial and wrist home BP monitoring (HBPM) devices. This analysis evaluated 82 patients who completed the 12-week treatment period. Among those who achieved target morning home SBP (<135 mmHg) and target bedtime home SBP (<135 mmHg), the brachial HBPM device showed achievement rates of 63.6% and 56.4%, respectively, for target nighttime home SBP (<120 mmHg). The wrist device showed achievement rates of 66.7% and 63.4%, respectively, for the same targets. Significant correlations were observed between both devices for nighttime home SBP measurements at baseline (r = 0.790), Week 12 (r = 0.641), and change from baseline to Week 12 (r = 0.533) (all, p < .001). In this patient population, approximately 60% of individuals who reached target morning or bedtime home SBP levels <135 mmHg exhibited well-controlled nighttime home SBP. Although nighttime home SBP measurements obtained using both brachial and wrist HBPM devices displayed a significant correlation, the wrist device needs to be examined in more detail for clinical use.

Primary aldosteronism (PA) is typically managed with mineralocorticoid receptor antagonists (MRAs) barring adrenalectomy. The efficacy of esaxerenone, a nonsteroidal MRA, were explored in patients with PA. Various parameters such as the urinary albumin to creatinine ratio (UACR) and serum levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) were evaluated in 25 PA patients before and 3 and 6 months after esaxerenone treatment. Systolic and diastolic blood pressure (BP), and the estimated glomerular filtration rate decreased after treatment, while serum levels of potassium and active renin increased. Significant reductions were observed in UACR 3 and 6 months after treatment. A significant decrease in NT-proBNP was evident at 6 months but not 3 months after treatment. Correlation analysis indicated that the reductions in BP and UACR at 3 months were independent of estimated daily salt intake. Furthermore, the effect of esaxerenone treatment on lowering UACR and NT-proBNP levels was independent of BP reduction. Responders whose systolic BP decreased 6 months after esaxerenone treatment by more than 10 mmHg compared to pretreatment had higher pretreatment NT-proBNP and similar UACR before and after treatment when compared with nonresponders. Esaxerenone improved mental, physical, and social quality of life (QOL) 6 months after treatment compared to healthy controls and increased over time. No patients discontinued treatment due to severe hyperkalemia or renal dysfunction. In conclusion, esaxerenone is a safe and effective MRA for PA treatment, offering significant benefits in terms of hypertension, albuminuria, NT-proBNP levels, and QOL improvement. Esaxerenone effectively lowers BP, UACR, and serum levels of NT-proBNP independent of dietary salt intake in mild PA patients.

Mineralocorticoid receptor (MR) is involved in the mechanisms of blood pressure elevation, organ fibrosis, and inflammation. MR antagonists have been used in patients with hypertension, heart failure, or chronic kidney disease. Esaxerenone, a recently approved MR blocker with a nonsteroidal structure, has demonstrated a strong blood pressure-lowering effect. However, blood pressure reduction may lead to sympathetic activation through the baroreflex. The effect of esaxerenone on the sympathetic nervous system remains unclear. We investigated the effect of esaxerenone on organ damage and the sympathetic nervous system in salt-loaded stroke-prone spontaneously hypertensive rats (SHRSP), a well-established model of essential hypertension with sympathoexcitation and organ damage. Three-week administration of esaxerenone or hydralazine successfully attenuated the blood pressure elevation. Both esaxerenone and hydralazine comparably suppressed left ventricular hypertrophy and urinary albumin excretion. However, renal fibrosis and glomerular sclerosis were suppressed by esaxerenone but not hydralazine. Furthermore, plasma norepinephrine level, a parameter of systemic sympathetic activity, was significantly increased by hydralazine but not by esaxerenone. Consistent with these findings, the activity of the control centers of sympathetic nervous system, the parvocellular region of the paraventricular nucleus in the hypothalamus and the rostral ventrolateral medulla, was enhanced by hydralazine but remained unaffected by esaxerenone. These results suggest that esaxerenone effectively lowers blood pressure without inducing reflex sympathetic nervous system activation. Moreover, the organ-protective effects of esaxerenone appear to be partially independent of its blood pressure-lowering effect. In conclusion, esaxerenone demonstrates a blood pressure-lowering effect without concurrent sympathetic activation and exerts organ-protective effects in salt-loaded SHRSP. Esaxerenone has antihypertensive and cardiorenal protective effects without reflex sympathetic activation in salt-loaded stroke-prone spontaneously hypertensive rats.

PURPOSE: Esaxerenone, a mineralocorticoid receptor blocker, attenuates global ischemia-induced myocardial damage and coronary endothelial dysfunction. This study aimed to determine whether esaxerenone exerted cardioprotective effects against cardioplegic arrest in Wistar rat hearts. METHODS: Isolated male Wistar rat hearts aerobically perfused via the Langendorff method for 20 min were randomly allocated to the Control (n = 6; perfused for an additional 10 min and subjected to no treatment) or Esax (n = 6; perfused with 0.1 µmol/L esaxerenone in perfusate for 10 min before ischemia) groups. Hearts in both groups were perfused with St. Thomas' Hospital No. 2 solution (STH2) for 2 min and subjected to 28 min of global ischemia. The recovery of left ventricular developed pressure (LVDP) and total troponin T leakage were measured after reperfusion. RESULTS: The final recovery of LVDP (expressed as a percentage of pre-ischemic value) in the Control and Esax groups was 50.8 ± 3.5% and 62.1 ± 5.6%, respectively (p <0.05, Esax vs. Control). The total troponin T leakage in the Control and Esax groups was 138.8 ± 18.5 ng/g heart wt and 74.3 ± 18.6 ng/g heart wt, respectively (p <0.05, Esax vs. Control). CONCLUSION: The administration of esaxerenone before cardioplegic arrest enhanced the cardioprotective effect exerted by STH2.

Proteinuria is a predictor of end-stage renal disease. The effectiveness of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker for the reduction in urinary protein excretion and renoprotection in proteinuric chronic kidney disease patients is well known, and coadministration of and sodium-glucose cotransporter inhibitor and the mineralocorticoid receptor blocker eplerenone has recently demonstrated an additive albuminuria-lowering effect in chronic kidney disease patients. Proteinuria is also an independent predictor of end-stage renal disease in kidney transplant recipients. Sodium-glucose cotransporter 2 inhibitors were administered to a 60-year-old man with chronic allograft kidney disease who had increasing urinary protein excretion with valsartan treatment. Although urinary protein excretion decreased drastically, it later increased to the same levels. A nonsteroidal mineralocorticoid receptor blocker, esaxerenone, was added to these medications, again resulting in a decrease in urinary protein excretion. Although the long-term renoprotective effect is not known, these medicines are promising and safe agents to reduce urinary protein excretion in patients with chronic allograft kidney disease.
RESUMO
INTRODUCTION: In contrast to the antihypertensive effect of esaxerenone, there is little evidence of its cardioprotective effect. We investigated the efficacy and safety of esaxerenone in patients with uncontrolled hypertension and left ventricular hypertrophy taking a renin-angiotensin system inhibitor (RASi) or calcium-channel blocker (CCB). METHODS: This was a multicenter, open-label, exploratory study with a 24-week treatment period. Esaxerenone was orally administered at an initial dose of 2.5 mg/day (maximum dose: 5 mg/day). The primary endpoints were the change in morning home systolic blood pressure (BP)/diastolic BP and change and percentage change in left ventricular mass index (LVMI) from baseline to end of treatment (EOT). Key secondary endpoints included change from baseline in bedtime home and office BP, achievement rate of target BP, and safety. RESULTS: In total, 60 patients were enrolled. Morning home systolic/diastolic BP was significantly decreased from baseline to EOT in the total population (- 11.5/ - 4.7 mmHg, p < 0.001) and in both the RASi and CCB subcohorts (all p < 0.01). Significant reductions in bedtime home and office BP were shown in the total population and both subcohorts. LVMI was also significantly decreased from baseline to EOT in the total population (- 9.9 g/m2, - 8.5%, both p < 0.001) and both subcohorts (all p < 0.05). The incidences of treatment-emergent adverse events (TEAEs) and drug-related TEAEs were 35.0% and 3.3%, respectively; most were mild or moderate. No new safety concerns were identified. CONCLUSION: Esaxerenone showed favorable antihypertensive and cardioprotective effects and safety in hypertensive patients with cardiac hypertrophy.
