Insights
Finerenone and SGLT2 inhibitors showed similar outcomes for mortality and hospitalization in patients with chronic kidney disease and heart failure. Finerenone demonstrated a potential, hypothesis-generating reduction in heart failure hospitalizations.
Area of Science:
- Cardiology
- Nephrology
- Pharmacology
Background:
- Finerenone and SGLT2 inhibitors offer cardiovascular and renal benefits in chronic kidney disease (CKD) and heart failure (HF).
- Limited real-world comparative data exists for these treatments in patients with both conditions.
- This study addresses the gap in real-world comparative effectiveness.
Purpose of the Study:
- To compare the real-world effectiveness and safety of finerenone versus SGLT2 inhibitors.
- To evaluate outcomes in patients with CKD stages 1-5 and heart failure (HFpEF).
- To generate hypotheses for future prospective trials.
Main Methods:
- Retrospective analysis of the TriNetX database.
- Comparison of adults (≥40 years) with CKD and HFpEF on finerenone versus SGLT2 inhibitors.
- Propensity score matching (1:1) to create comparable cohorts (n=333 each), followed by Kaplan-Meier and Cox modeling.
Main Results:
- All-cause mortality and hospitalization rates were similar between finerenone and SGLT2 inhibitor groups at 6 months and 1 year.
- A modest, borderline reduction in heart failure hospitalization was observed with finerenone at 1 year (HR 0.81; 95% CI 0.66-0.99).
- No significant differences in safety outcomes were noted between the treatment groups.
Conclusions:
- In real-world practice, finerenone demonstrated comparable safety and effectiveness to SGLT2 inhibitors for mortality and renal outcomes in CKD and HFpEF patients.
- The observed reduction in HF hospitalizations with finerenone is hypothesis-generating and requires cautious interpretation.
- Prospective head-to-head trials are needed to confirm findings and guide optimal treatment strategies.
Abstract:
Background: Finerenone and sodium-glucose cotransporter-2 inhibitors provide cardiovascular and renal benefits in patients with chronic kidney disease (CKD) and heart failure (HF), but real-world comparative evidence is limited. Methods: This retrospective study used the TriNetX database. Adults ≥ 40 years with CKD stages 1-5 and HF [LVEF > 40%; excluding end-stage renal disease (ESRD) or dialysis] receiving finerenone were compared with those on SGLT2 inhibitors. Propensity score matching (1:1) yielded 333 patients per cohort. Kaplan-Meier and Cox models estimated hazard ratios (HRs) with 95% confidence intervals. Results: After matching, baseline characteristics were reasonably balanced, with some residual imbalance remaining. All-cause mortality was similar between finerenone and SGLT2 inhibitors at 6 months (HR 0.98; 95% CI 0.50-1.90) and 1 year (HR 0.93; 95% CI 0.53-1.66). All-cause hospitalization or ER visits were also comparable at 6 months (HR 1.07; 95% CI 0.84-1.36) and 1 year (HR 1.04; 95% CI 0.83-1.29). Finerenone was associated with a modest, borderline reduction in HF hospitalization at 1 year, without consistent effects across timepoints or a mortality benefit; thus, this finding is hypothesis-generating (HR 0.81; 95% CI 0.66-0.99). Safety outcomes were similar between groups. Conclusions: In this real-world analysis, finerenone was associated with similar all-cause mortality, overall hospitalization, and renal safety outcomes compared with SGLT2 inhibitors, with a modest reduction in HF hospitalization at 1 year that should be interpreted cautiously given the exploratory nature of the study. These findings are hypothesis-generating and underscore the need for prospective head-to-head trials to better define optimal therapy sequencing in patients with HFpEF and CKD.

Renal Drug Clearance: Comparison Between Renal Excretion Methods
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

Renal Drug Excretion: Overview
A nephron consists of two primary structures: the renal corpuscle and the renal tubule. The renal corpuscle contains the glomerulus, a network of capillaries where the first step of renal excretion, glomerular filtration, occurs. Blood pressure forces water, ions, and small molecules out...
