Cardiovascular Genistein Therapy for Heart Failure Inflammation
A Pilot Clinical Trial of Cardiovascular Genistein Therapy for Heart Failure Inflammation
Cardiovascular Genistein Therapy for Heart Failure Inflammation (NCT06501768) is a Phase 1 / Phase 2 interventional studying Heart Failure, sponsored by University Medical Centre Ljubljana. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
This Phase 1b/2a open-label study is designed to assess the safety and efficacy of genistein in patients with heart failure (HF). The investigation will focus on its impact on inflammatory and cardiometabolic biomarkers, as well as its effects on cardiac function and exercise capacity. Blood samples will be collected at baseline, following each administration of genistein, and after a six-week placebo washout period. These samples will be subjected to comprehensive analyses to evaluate inflammatory cytokines and novel molecular markers. Routine tests, including Complete Blood Count (CBC), Basic Metabolic Panel (Chem 7), Liver Function Tests (LFT), Hemoglobin A1c (HbA1c), N-terminal pro b-type natriuretic peptide (NT-proBNP), C-Reactive Protein (CRP), and troponin T will be performed. Advanced assessments will include RNA sequencing (RNA-seq) on peripheral blood mononuclear cells (PBMCs) and the isolation of plasma exosomes to identify inflammatory biomarkers. In addition, a subset of the blood samples will be used to generate induced pluripotent stem cells (iPSCs) to further explore the treatment's impact on heart failure-related inflammatory markers. Echocardiography, in accordance with the European Society of Cardiology (ESC) and the American Heart Association (AHA) guidelines, will be utilized to evaluate cardiac structure and function with a specific focus on the left and right ventricular functions and valvular integrity. Exercise capacity will be gauged through a standardized six-minute walk test. Levels of NT-proBNP will be measured as an indicator of cardiac stress and function. Participants will be followed up for 18 weeks post-enrolment, with the primary endpoint being the change in inflammatory markers from baseline to the three-month mark. Secondary endpoints will include changes in cardiac function and exercise capacity over the same period. The trial aims to enrol 40 participants, following ethical committee approval and the acquisition of written informed consent. Each patient will receive genistein at a dosing regimen starting with 250 mg twice daily (BID) for 4 weeks, escalating to 500 mg BID for the subsequent 4 weeks, and 750 mg BID for another 4 weeks, culminating in a 6-week follow-up period. The insights garnered from this study are expected to be pivotal in guiding future larger-scale studies and to elucidate the therapeutic potential of genistein in the management of heart failure.
What Stage of Research Is This?
Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Heart Failure, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
With a target enrollment of 40 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who can participate in NCT06501768?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT06501768?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
