Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• HF inflammatory and cardiometabolic markers

  To comprehensively assess the safety profile and determine the impact of Genistein on key inflammatory and cardiometabolic biomarkers in patients with HF, the following markers will be assessed using specific measurement tools: Inflammatory Markers: * Interleukin-6 (IL-6): Measured using ELISA. * Interleukin-8 (IL-8): Measured using ELISA. * Tumor Necrosis Factor-alpha (TNF-α): Measured using ELISA. * Interferon-gamma (IFN-γ): Measured using ELISA. Cardiometabolic Markers: * B-type Natriuretic Peptide (BNP): Measured using immunoassay. * C-reactive Protein (CRP): Measured using immunoassay. * Hemoglobin A1C (HgA1C): Measured using standard laboratory methods. * Complete Blood Count (CBC): Measured using automated hematology analyzer. * Comprehensive Metabolic Panel (Chem 7): Measured using standard laboratory methods. * Liver Function Tests (LFT): Measured using standard laboratory methods.

Genistein Therapy

EXPERIMENTAL

Participants will consume 250 mg of genistein BID (500 mg total) by mouth for the first 4 weeks before blood samples are collected. And then, patients will take 500 mg of genistein BID (1000 mg total) for the next 4 weeks before blood are collected. Afterward, patients will take 750 mg of genistein BID (1500 mg total) for 4 weeks before blood samples are collected. Afterward, patients will be off Genistein for 6 weeks before returning for blood sample collection. The Genistein capsules are manufactured and obtained from MCS Formulas. The genistein is certified to be 98% pure genistein by HPLC and is good laboratory practice (GLP) certified. At baseline, and again before Genistein discontinuation (at 12 weeks), we will also perform transthoracic echocardiography and a 6-minute walk test.
