Simultaneous initiation of finerenone and empagliflozin across the spectrum of kidney risk in the CONFIDENCE trial
Abstract
ABSTRACT Background The CONFIDENCE (COmbinatioN effect of FInerenone anD EmpaglifloziN in participants with CKD and type 2 diabetes using a UACR Endpoint) trial investigated the safety and efficacy of simultaneously initiating finerenone and empagliflozin for patients with chronic kidney disease (CKD) and type 2 diabetes. This prespecified analysis aimed to determine if the predicted risk of kidney disease progression, based on KDIGO risk categories, influenced the benefits and safety of this combination therapy. Methods The double-blind, double-dummy trial randomized 818 adults with CKD and type 2 diabetes [urine albumin–creatinine ratio (UACR) ≥100 to 30% reduction in UACR (secondary endpoint) across KDIGO risk categories was assessed. Results At baseline, among 781 with available data, 11.3% of participants were classified as low/moderate risk, 29.6% as high risk and 59.2% as very high risk. At 180 days, combination therapy significantly reduced UACR levels across all KDIGO risk categories (low/moderate: –61.7%; high: –60.7%; very high: –52.4%). This reduction was consistently greater than that achieved with either monotherapy alone. More than half of patients on combination therapy experienced UACR reductions of >30% (low/moderate: 58.1%; high: 74.2%; very high: 70.6%), again outperforming monotherapies across all risk groups. While hyperkalemia was more common with combination therapy, early eGFR declines (>30% within 30 days) were less frequent in individuals with…
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: 818 participants or records.
