Impact of Baseline GLP-1 Receptor Agonist Use on Albuminuria Reduction and Safety With Simultaneous Initiation of Finerenone and Empagliflozin in Type 2 Diabetes and Chronic Kidney Disease (CONFIDENCE Trial)
Abstract
Objective: The CONFIDENCE trial demonstrated additive benefits of simultaneous initiation of finerenone, a nonsteroidal mineralocorticoid receptor antagonist, and a sodium-glucose cotransporter 2 (SGLT2) inhibitor compared with monotherapy in reducing the urinary albumin-to-creatinine ratio (UACR). This prespecified analysis evaluated whether safety and efficacy of combination therapy varies by baseline glucagon-like peptide 1 receptor agonist (GLP-1 RA) use.
Research design and methods: Adults with chronic kidney disease (UACR ≥100 to <5,000 mg/g; estimated glomerular filtration rate [eGFR] 30-90 mL/min/1.73 m2) and type 2 diabetes (glycated hemoglobin <11% [97 mmol/mol]) were randomized (1:1:1) to once-daily finerenone, empagliflozin, or finerenone plus empagliflozin.
Results: Among 800 participants, 182 (23%) used a GLP-1 RA at baseline. At day 180, UACR change from baseline in participants using a GLP-1 RA was -51% (95% CI -59 to -40%) with combination therapy, -34% (-48 to -18%) with finerenone, and -36% (-48 to -21%) with empagliflozin. Corresponding results in those not using a GLP-1 RA at baseline were -56% (-62 to -50%), -37% (-45 to -28%), and -33% (-41 to -23%), respectively. Hyperkalemia incidence rates with combination therapy were 9.0% and 9.5% among individuals with and without baseline GLP-1 RA use. eGFR changes were consistent among individuals with and without baseline GLP-1 RA use. Acute kidney injury was uncommon. Decreases in systolic blood pressure were…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 800 participants or records.
