BACKGROUND AND AIMS: Evidence from clinical trials demonstrates that finerenone reduces the risk of cardiovascular and renal complications among patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). What is lacking is the evidence on finerenone use in real-world clinical practice.

METHOD: The present analysis is based on a longitudinal single-arm cohort study of patients initiating finerenone between July 2021 and August of 2023 and with prior diagnoses of CKD and T2D. Data were obtained from US electronic health records and insurance claims (OM1 Real-World Data CloudTM). CKD was defined as either having 1 diagnostic code for CKD stage 2-4 or unspecified stage, two estimated glomerular filtration rate (eGFR) measurements between 15 and 60 ml/min/1.73 m2, or two urine albumin to creatinine ratio (UACR) measurements over 30 mg/g; T2D was defined as having a diagnostic code for T2D. We described patient demographics, comorbidities, and comedications at baseline (365 days prior and including index date), and incidence rates of cardiovascular and renal outcomes, including eGFR and UACR changes over time. The presented analysis (NCT05703880) is part of the multi-national, multi-database observational research platform FOUNTAIN.

RESULTS: We identified 28,056 new users of finerenone with prior CKD and T2D. The users had a mean (SD) age of 68.8 (10.8) years and 44.8% were female. Comorbidities of interest at baseline were hypertension (89.8%), cardiovascular disease (21.2%), neuropathy (13.4%), retinopathy (8.1%), heart failure (7.9%), and cerebrovascular disease (4.2%). Assessment of comedication use at baseline indicates that patients who initiate finerenone had exposure to renin–angiotensin system inhibitors (52.5%), sodium-glucose cotransporter-2 inhibitors (39.2%), or glucagon-like peptide-1 receptor agonists (27.4%) within 180 days prior to initiating finerenone. Overall, 82.5% of patients initiated finerenone at 10 mg/d, while 17.5% of patients started with 20 mg/d. Complete results including incidence rates of cardiovascular and renal outcomes, hyperkalemia events, and changes in kidney function measures (eGFR, UACR) during follow-up will be presented as part of the conference presentation.

CONCLUSION: Data from patients receiving finerenone as part of clinical practice in the USA suggest that finerenone is used concurrently with other renal and cardiovascular protective medication-classes recommended for patients with CKD and T2D.
