Finerenone treatment for cardiovascular issues in diabetes

Finerenone Treatment for Diabetic Cardiovascular Autonomic Neuropathy: the FibroCAN Study

Phase 2 Interventional Steno Diabetes Center Copenhagen · NCT06906081

This study is testing if a medication called finerenone can help people with type 2 diabetes who have early signs of heart and nerve problems feel better.

What this trial studies

This clinical trial investigates the effectiveness of finerenone, a mineralocorticoid receptor antagonist, in treating cardiovascular autonomic neuropathy (CAN) in patients with type 2 diabetes. It is a double-blind, randomized, placebo-controlled trial involving 100 participants over 78 weeks. The study aims to determine if finerenone can improve symptoms of early-stage CAN and assess its impact on other types of neuropathy. Participants will be randomly assigned to receive either finerenone or a placebo.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 40 and older with type 2 diabetes and early-stage cardiovascular autonomic neuropathy.

Not a fit: Patients with definite cardiovascular autonomic neuropathy or those with severe comorbid conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve cardiovascular health and reduce complications for patients with type 2 diabetes suffering from CAN.

How similar studies have performed: While the approach of using finerenone is novel for treating CAN, similar studies targeting diabetic neuropathies have shown promising results.
