Finerenone Treatment for Diabetic Cardiovascular Autonomic Neuropathy: the FibroCAN Study
Peter Rossing
100 participants

INTERVENTIONAL
Conditions
Summary
Diabetic neuropathy is a serious and common complication of diabetes that currently has no cure. One form of this condition is cardiovascular autonomic neuropathy (CAN), which affects about 20% of people with diabetes-an estimated 100 million people worldwide. CAN is a significant risk factor for death and health problems like heart disease and kidney damage, and may contribute to the high rates of cardiovascular-related deaths in people with diabetes. This study is a double-blind, randomized, placebo-controlled, two-center trial. The study aims to test whether finerenone can treat cardiovascular autonomic neuropathy in patients with type 2 diabetes. The trial will evaluate the effects of 78 weeks of treatment with finerenone or a placebo, assigned randomly in a 1:1 ratio, on early-stage cardiovascular autonomic neuropathy. The trial will include 100 participants with type 2 diabetes. Additionally, the study will investigate how the treatment impacts other types of neuropathy and related pathological mechanisms.
Eligibility
Inclusion Criteria4
- Given informed consent
- Type 2 diabetes defined by WHO criteria
- Aged 40 ≥ at inclusion
- Pathological E/I ratio (Mean value of three measures)
Exclusion Criteria24
- No CAN (no abnormal CARTs)
- Definite CAN (more than one abnormal CART)

Subjects of childbearing potential must agree to use a highly effective form of contraception throughout the duration of the study (list of definition on WOCBP and accepted contraception in appendix A).

- Treatment with strong CYP3A4-inhibitors (e.g. Itraconazol, ketoconazol, ritonavir, cobicistat, clarithromycin) which cannot be discontinued 4 weeks prior to screening visit
- Treament with moderate to strong CYP3A4-induceres (e.g. rifampicin, carbamazepine, phenytoin, phenobarbital, St John's Wort or efavirenz) which cannot be discontinued 4 weeks prior to screening visit
- Have received chemotherapeutic treatment within last 12 months
- Grapefruit consumption that cannot be discontinued during the study period
- Inability to complete study protocol, assessed to investigator
- Not able to read, write and/or understand Danish
Interventions
Titration of finerenone will be based on baseline eGFR. Participants with eGFR \> 60 mL/min/1.73m² will start on a 20mg dosage. Medication dosage will be increased to 40 mg after one month if serum potassium \< 4.8 mmol/l. If side effects occur at any dosage, the dosage will be reduced to the previous level. Participants with eGFR \< 60 and \>25 Participants with eGFR \< 60 mL/min/1.73m² (and eGFR \< 25 mL/min/1.73m²) will start on a 10mg dosage. Medication dosage will be increased to 20 mg after one month if serum potassium \< 4.8 mmol/l. Subsequently, Medication dosage will be increased to 40 mg after an additional one month if serum potassium \< 4.8 mmol/l. If side effects occur at any dosage, the dosage will be reduced to the previous level. Finerenone is administered orally as immediate release tablets.
Placebo tablets matching BAY94-8862 are administered orally.
