Abstract
This pooled subanalysis of five multicenter, prospective, open-label, single-arm studies on esaxerenone aimed to evaluate the efficacy, organ-protective effects, and safety of esaxerenone in hypertensive patients with type 2 diabetes mellitus (T2DM), with and without concomitant sodium-glucose cotransporter-2 inhibitor (SGLT2i) therapy. In total, 283 and 279 patients were included in the safety (with SGLT2i, 148; without, 135) and full analysis sets (with SGLT2i; 145; without, 134), respectively. Significant changes in morning home systolic/diastolic blood pressure (SBP/DBP) from baseline to Week 12 were shown in the overall population (mean change: -11.9/-5.2 mmHg, both P < 0.001) and both SGLT2i and non-SGLT2i subgroups (-11.3/-4.8 and -12.5/-5.7 mmHg, respectively, all P < 0.001). Similar findings were observed in bedtime home and office SBP/DBP. The proportions of patients who achieved target home SBP/DBP < 135/85 mmHg were 71.2% (overall population) and 70.5% and 71.9% in the SGLT2i and non-SGLT2i subgroups, respectively. The urine albumin-to-creatinine ratio significantly improved from baseline to Week 12 in the overall population and SGLT2i subgroups (percentage change in geometric mean from baseline: -42.8%, -43.0%, and -42.6%, respectively, all P < 0.001). N-terminal pro-B-type natriuretic peptide levels improved in all groups. The incidence of serum potassium ≥5.5 mEq/L was 2.0% vs 5.2% in the SGLT2i vs non-SGLT2i subgroups. Esaxerenone demonstrated significant BP-lowering effects, and improved renal and cardiovascular parameters, regardless of SGLT2i use. Safety was consistent across groups, with the numerically lower incidence of serum potassium ≥5.5 mEq/L in the SGLT2i subgroup suggesting a potential mitigating effect of SGLT2is on the risk of hyperkalemia.
