Genistein treatment for heart failure inflammation

A Pilot Clinical Trial of Cardiovascular Genistein Therapy for Heart Failure Inflammation

Phase1; Phase2 Interventional University Medical Centre Ljubljana · NCT06501768

What this trial studies

This Phase 1b/2a open-label study evaluates the safety and efficacy of genistein in patients with heart failure. The study focuses on its effects on inflammatory and cardiometabolic biomarkers, cardiac function, and exercise capacity. Blood samples will be collected at various stages to analyze inflammatory cytokines and other molecular markers, alongside routine tests. Advanced assessments will include RNA sequencing and the isolation of plasma exosomes to identify inflammatory biomarkers.

Who should consider this trial

Good fit: Ideal candidates include individuals with heart failure of ischemic or nonischemic origin and an LVEF of less than 40%.

Not a fit: Patients with recent coronary interventions, certain cancers, or those on specific diets or supplements may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve heart function and reduce inflammation in patients with heart failure.

How similar studies have performed: While the approach is innovative, similar studies have shown promise in targeting inflammation in heart failure, suggesting potential for success.
