Background

This study aimed to evaluate the renal outcomes associated with finerenone use in a Turkish diabetic chronic kidney disease (CKD) cohort.

Methods

This study demonstrated initial and first month data of adult participants with diabetic CKD who received finerenone in 34 nephrology units in Turkey between February 2024 to April 2025. Key outcomes included changes in estimated glomerular filtration rate (eGFR), urinary albumin-creatinine ratio (UACR), serum potassium levels, and adverse events.

Results

A total of 366 participants were included. Baseline eGFR was 58.24±25.68 mL/min/1.73m2 and median UACR was 1586 mg/g. The mean level of serum potassium was 4.54±0.72 mmol/L. All participants were receiving renin-angiotensin system (RAS) inhibitors, and 94% were concurrently treated with an SGLT2 inhibitor.
Forty one % reduction in albuminuria was observed at 1 month following using finerenone.
After 1 month using of finerenone, 12 of 366 (3.27%) participants showed hyperpotassemia (>5.5 mmol/L). Eight of 12 hyperpotassemic participants, complication was managed by adding calcium polystyrene sulfonate; while in the remaining 4 patients, finerenone was temporarily discontinued.

Conclusion

This real-world multi-center cohort preliminary data suggests that finerenone is effective and well tolerated in diabetic CKD in Turkish population. Ongoing surveillance and further real-world evidence studies will be crucial to optimize diabetic chronic kidney disease treatment regimens in diverse populations.
