Abstract:

BACKGROUND: Finerenone, a selective non-steroidal mineralocorticoid receptor antagonist, improves kidney and cardiovascular outcomes in patients with chronic kidney disease (CKD) associated with type 2 diabetes (T2D). The FINE-REAL study (NCT05348733) aims to evaluate the characteristics and treatment patterns of participants treated with finerenone in clinical practice. METHODS: FINE-REAL is a prospective, single-arm, non-interventional study of patients initiated on finerenone as part of their routine care in accordance with country-approved labels. The study, initiated in June 2022, is expected to be completed by January 2028. The cutoff for this pre-specified interim analysis was June 13, 2023. RESULTS: Participants were recruited across nephrology, endocrinology, cardiology, and primary care settings. Of 556 participants enrolled in the study by the cut-off date, 504 were included in this analysis (median follow-up duration of 7 months [finerenone treatment initiation to last recorded observation]). At baseline, 76.1% of participants were in the high or very high (KDIGO) CKD risk categories. Angiotensin converting enzyme inhibitors/angiotensin receptor blockers and sodium-glucose cotransporter 2 inhibitors were prescribed to 71.8% and 46.6% of participants, respectively. Based on prescribing information, 87.9% and 12.1% of participants initiated finerenone at doses of 10 and 20 mg, respectively. Finerenone treatment was uninterrupted in 92.3% of participants after 7 months'' median follow-up. Treatment-emergent adverse events occurred in 110 (21.8%) participants. Hyperkalemia occurred in 25 (5.0%) participants, with no cases leading to death, dialysis, or hospitalization. CONCLUSION: At this interim analysis, finerenone was initiated in patients with CKD and T2D across various clinical practices participating in the study. Treatment discontinuation and hyperkalemia occurred infrequently.
