Long-term effects of esaxerenone in patients with type 2 diabetes, diabetic kidney disease, and hypertension (JDDM77).

Abstract

Objectives: This clinical study assessed the three-year, long-term effects of esaxerenone, a non-steroidal aldosterone receptor blocker, on Japanese patients with type 2 diabetes, diabetic kidney disease, and hypertension who were receiving renin-angiotensin system inhibitors.

Materials and methods: Data from a computerized diabetic care database were used to retrospectively compare esaxerenone users (Group A) with non-esaxerenone users (Group B). Propensity score weighting was applied to Group B. The study primarily focused on percent changes in the Urine Albumin-Creatinine Ratio (UACR) from baseline and also examined the estimated Glomerular Filtration Rate (eGFR), blood pressure, serum potassium levels, and HbA1c.

Results: There were 199 patients in Group A and 199 in Group B, matched 1:1 using propensity scores. UACR and blood pressure were significantly lower in Group A than in Group B. Geometric mean percent changes in UACR from baseline between the two groups were as follows: - 62.7% at 1 year (95% Confidence Interval (CI): - 91.0 to - 34.1%), - 48.9% at 2 years (95% CI: - 79.4 to - 19.3%), and - 63.8% at 3 years (95% CI: - 107.4 to - 20.2%). Additionally, the present study examined the impact of combining esaxerenone with SGLT2 inhibitors and GLP-1 receptor agonists and showed consistent effects on UACR irrespective of these medications. Esaxerenone slightly lowered eGFR with a low risk of hyperkalemia but did not adversely impact glucose metabolism.

Conclusions: Esaxerenone exerted antihypertensive and antialbuminuric effects in patients with type 2 diabetes, diabetic kidney disease, and hypertension.
