Discovery of Apararenone (MT-3995) as a Highly Selective, Potent, and Novel Nonsteroidal Mineralocorticoid Receptor Antagonist

Overactivation of the mineralocorticoid receptor (MR) is involved in many diseases, such as hypertension, kidney disease, and heart failure. Thus, MR antagonists (MRAs) are expected to be beneficial to patients with these diseases. In order to identify novel nonsteroidal MRAs that overcome the issues of already marketed steroidal MRAs, we searched for new compounds guided by our hypothesis that T-shaped compounds with a hydrophobic core structure, two polar functional groups at both extremities able to interact with MR, and a bulky substituent that can interfere with the folding of the C-terminal helix 12 may exhibit antagonist activity toward MR. We discovered that the novel 1,4-benzoxazin-3-one derivative 19 (apararenone: MT-3995) acted as a highly selective and potent nonsteroidal MRA. Apararenone exhibited a more potent antihypertensive and organ-protective activity than steroidal MRA eplerenone in a primary aldosteronism rat model obtained by infusing aldosterone in uninephrectomized rats.

Efficacy and safety of apararenone (MT-3995) in patients with nonalcoholic steatohepatitis: A randomized controlled study

Aim: To evaluate the efficacy, safety, and tolerability of apararenone 10 mg/day in patients with nonalcoholic steatohepatitis (NASH).
Methods: In this multicenter, randomized, double-blind, placebo-controlled phase II study, patients received apararenone 10 mg or placebo once daily for 72 weeks. The primary efficacy end-point was percent change in serum alanine aminotransferase (ALT) from baseline to 24 weeks after randomization. Secondary efficacy end-points included changes in liver fibrosis markers. Adverse drug reactions (ADRs) and serum potassium levels were evaluated.
Results: Forty-eight patients were randomly assigned to treatment (placebo, 23; apararenone, 25). The percent change in ALT at 24 weeks was -3.0% and -13.7% with placebo and apararenone, respectively (p = 0.308). The apararenone group showed greater reductions from baseline in fibrosis markers (type IV collagen 7S and procollagen-3 N-terminal peptide) and noninvasive tests of fibrosis (enhanced liver fibrosis score and Fibrosis-4 index) at all time points versus placebo. The percentage of patients with improvement of 1 point or more in fibrosis stage/without nonalcoholic fatty liver disease activity score worsening was 41.7% with apararenone and 26.1% with placebo (p = 0.203). Adverse drug reactions were reported in three (13.0%) and three (12.5%) patients in the placebo and apararenone groups, respectively. Serum potassium levels increased in the apararenone group during the study and decreased to near baseline after the end of treatment.
Conclusions: In patients with NASH, apararenone 10 mg/day for 72 weeks was effective in decreasing ALT levels, improved multiple potential fibrosis markers, and was safe and well tolerated. Pathological findings showed anti-inflammatory and antifibrotic effects of apararenone.

Novel non-steroidal mineralocorticoid receptor antagonists in cardiorenal disease

Mineralocorticoid receptor antagonists (MRAs) are key agents in guideline-oriented drug therapy for cardiovascular diseases such as chronic heart failure with reduced ejection fraction and resistant hypertension. Currently available steroidal MRAs are efficacious in reducing morbidity and mortality; however, they can be associated with intolerable side effects including hyperkalaemia in everyday clinical practice. Recently, a new class of non-steroidal MRAs (including esaxerenone, AZD9977, apararenone, KBP-5074 and finerenone) have been developed with an improved benefit-risk profile and a novel indication for finerenone for diabetic kidney disease. To better understand the non-steroidal MRAs, this review provides information on the molecular pharmacology as well as relevant current preclinical and clinical data on cardiorenal outcomes. A comparative review of all compounds in the class is discussed with regard to clinical efficacy and safety as well as a perspective outlining their future use in clinical practice.

Role of mineralocorticoid receptor antagonists in kidney diseases

Mineralocorticoid receptor (MR) antagonists, for example, spironolactone and eplerenone, are in clinical use to treat hypertension. Increasing evidence suggests that mineralocorticoid receptor activation causes the pathogenesis and progression of chronic kidney disease. Aldosterone-induced MR activation increases inflammation, fibrosis, and oxidative stress in the kidney. MR antagonists (MRAs) have demonstrated therapeutic actions in chronic kidney disease (CKD), diabetic nephropathy (DN), renal fibrosis, and drug-induced renal injury in preclinical and clinical studies. We have summarized and discussed these studies in this review. The nonsteroidal MRA, esaxerenone, recently received approval for the treatment of hypertension. It has also shown a positive therapeutic effect in phase 3 clinical trials in patients with DN. Other nonsteroidal MRA such as apararenone, finerenone, AZD9977, and LY2623091 are in different clinical trials in patients with hypertension suffering from renal or hepatic fibrotic diseases. Hyperkalemia associated with MRA therapy has frequently led to the discontinuation of the treatment. The new generation nonsteroidal MRAs like esaxerenone are less likely to cause hyperkalemia at therapeutic doses. It appears that the nonsteroidal MRAs can provide optimum therapeutic benefit for patients suffering from kidney diseases.

New mineralocorticoid receptor antagonists: update on their use in chronic kidney disease and heart failure

Aldosterone is a mineralocorticoid hormone with a well-known effect on the renal tubule leading to water retention and potassium reabsorption. Other major effects of the hormone include the induction of proinflammatory activity that leads to progressive fibrotic damage of the target organs, heart and kidney. Blocking the aldosterone receptor therefore represents an important pharmacological strategy to avoid the clinical conditions deriving from heart failure (CHF) and chronic kidney disease (CKD). However, steroidal mineralocorticoid receptor antagonists (MRA) have a low safety profile, especially in CKD patients due to the high incidence of hyperkalemia. A new generation of nonsteroidal MRA has recently been developed to obtain a selective receptor block avoiding side-effects like hyperkalemia and thereby making the drugs suitable for administration to CKD patients. This review summarizes the results of published preclinical and clinical studies on the nonsteroidal MRA, apararenone esaxerenone and finerenone. The trials showed a better safety profile with maintained drug efficacy compared with steroidal MRA. For this reason, nonsteroidal MRA represent an interesting new therapeutic approach for the prevention of CHF and CKD progression. Some basic research findings also yielded interesting results in acute clinical settings such as myocardial infarction and acute kidney injury.
