美國芝加哥大學George L. Bakris團隊研究了Finerenone治療2型糖尿病慢性腎臟病對患者預後的影響。2020年10月23日,該研究發表在《新英格蘭醫學雜誌》上。
在涉及慢性腎臟病(CKD)和2型糖尿病患者的短期試驗中,非甾體類選擇性鹽皮質激素受體拮抗劑Finerenone降低了白蛋白尿,但其對腎臟和心血管結局的長期影響尚不清楚。
在這項雙盲試驗中,研究組招募了5734名CKD和2型糖尿病患者,按1:1隨機分配,分別接受Finerenone或安慰劑治療。這些患者的尿白蛋白與肌酐之比(白蛋白以毫克為單位,肌酐以克為單位)小於或等於300,估計腎小球濾過率(eGFR)為25-60 ml/min/1.73m2(體表面積),伴糖尿病性視網膜病變,或尿白蛋白/肌酐比為300至5000,eGFR為25-75 ml/min/1.73m2。主要複合終點為腎功能衰竭、eGFR持續下降至少40%(基線)或腎臟原因死亡。關鍵次要複合終點為心血管原因死亡、非致命性心肌梗塞、非致命性中風或因心力衰竭住院。
在2.6年的中位隨訪期間,Finerenone組2833例患者中有504例(17.8%)發生主要複合終點,安慰劑組2841例患者中有600例(21.1%),組間差異顯著。Finerenone組中有367例患者(13.0%)發生關鍵次要複合終點,顯著低於安慰劑組(420例,14.8%)。總體而言,兩組間不良事件發生率相似。Finerenone組中因高鉀血症而停藥的發生率為2.3%,顯著高於安慰劑組(0.9%)。
總之,Finerenone治療CKD和2型糖尿病患者,與安慰劑相比,可顯著降低CKD進展和心血管事件的風險。

Abstract:
Background
Finerenone, a nonsteroidal, selective mineralocorticoid receptor antagonist, reduced albuminuria in short-term trials involving patients with chronic kidney disease (CKD) and type 2 diabetes. However, its long-term effects on kidney and cardiovascular outcomes are unknown.
Methods
In this double-blind trial, we randomly assigned 5734 patients with CKD and type 2 diabetes in a 1:1 ratio to receive finerenone or placebo. Eligible patients had a urinary albumin-to-creatinine ratio (with albumin measured in milligrams and creatinine measured in grams) of 30 to less than 300, an estimated glomerular filtration rate (eGFR) of 25 to less than 60 ml per minute per 1.73 m2 of body-surface area, and diabetic retinopathy, or they had a urinary albumin-to-creatinine ratio of 300 to 5000 and an eGFR of 25 to less than 75 ml per minute per 1.73 m2. All the patients were treated with renin–angiotensin system blockade that had been adjusted before randomization to the maximum dose on the manufacturer’s label that did not cause unacceptable side effects. The primary composite outcome, assessed in a time-to-event analysis, was kidney failure, a sustained decrease of at least 40% in the eGFR from baseline, or death from renal causes. The key secondary composite outcome, also assessed in a time-to-event analysis, was death from cardiovascular causes, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure.
Results
During a median follow-up of 2.6 years, a primary outcome event occurred in 504 of 2833 patients (17.8%) in the finerenone group and 600 of 2841 patients (21.1%) in the placebo group (hazard ratio, 0.82; 95% confidence interval [CI], 0.73 to 0.93; P=0.001). A key secondary outcome event occurred in 367 patients (13.0%) and 420 patients (14.8%) in the respective groups (hazard ratio, 0.86; 95% CI, 0.75 to 0.99; P=0.03). Overall, the frequency of adverse events was similar in the two groups. The incidence of hyperkalemia-related discontinuation of the trial regimen was higher with finerenone than with placebo (2.3% and 0.9%, respectively).
Conclusions
In patients with CKD and type 2 diabetes, treatment with finerenone resulted in lower risks of CKD progression and cardiovascular events than placebo.
