Background
The nonsteroidal mineralocorticoid receptor antagonist finerenone and the sodium-glucose co-transporter-2 inhibitor canagliflozin reduce cardiorenal risk in albuminuric patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). At first glance, the results of FIDELIO-DKD (ClinicalTrials.gov, NCT02540993) and CREDENCE appear disparate. In FIDELIO-DKD, the primary end-point had a 18% (95% CI 7% to 27%) relative risk reduction; in CREDENCE the primary end-point had a 30% (95% CI 18% to 41%) relative risk reduction. Unlike CREDENCE, FIDELIO-DKD trial included patients with high albuminuria but excluded patients with symptomatic heart failure with reduced ejection fraction. The primary end-point in the FIDELIO-DKD trial was kidney specific and included a sustained decline in eGFR of ≥40% from baseline. In contrast, the primary end-point in the CREDENCE trial was included a sustained decline in eGFR of ≥57% from baseline and cardiovascular death. This post-hoc exploratory analysis investigated how differences in trial design—inclusion/exclusion criteria and definition of primary outcomes— influenced observed treatment effects.
