What this study is about

This study aims to assess the safety tolerability, adherence and effectiveness of genistein as an anti-obesity treatment for children and adolescents. The primary goal is determining how well genistein is tolerated and adhered to by pediatric patients with obesity. Secondary goals include evaluating its impact on body mass index z-scores and cardiometabolic risk factors, such as inflammation. Participants aged 4-18 will be recruited from the Paediatric HEAL (Healthy Eating, Activity \& Lifestyle) Program at the Children's Hospital - London Health Science Center in London, Ontario. They will receive genistein treatment over 6 months, with interim assessments at 3 and 6 months to monitor efficacy, safetytolerability, and adherence, and efficacy, and potentially increase the dose at the 3-month visit. A final assessment will occur after a 3-month washout to observe any lasting effects. Blood and urine samples will be collected to analyze various adherence and health markers, including inflammatory and cardiometabolic factors. For participants who are of childbearing potential and have had their first menses, the blood analysis will also include pregnancy testing. Laboratory testing will be performed at baseline, at three and six months while taking genistein and three months after the washout period. Urine samples will also confirm that genistein has been taken appropriately throughout the study. The study expects that genistein will be well-tolerated by children, reduce BMI z-scores by 0.2 (0.5), and improve cardiometabolic risk factors such as blood pressure, lipid profiles, and inflammation. A sample size of 60 participants has been calculated to achieve statistically significant results, which will inform more extensive studies on genistein's potential for managing pediatric obesity.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Children and adolescents aged 4-17 years. * Obesity defined as a BMI z-score ≥ 2 for age and sex, based on World Health Organization (WHO) reference standards. * Stable or increasing BMI after at least 3 months of enrollment in the HEAL program. * Inclusion of participants from all backgrounds, consistent with principles of equity, diversity, and inclusion. * Participants and families who do not speak or read English will be included, provided interpreter services are available at LHSC's Children's Hospital. * Participants who decline to enroll will continue receiving standard care in the HEAL program. Exclusion Criteria: * Known allergy to Sophora japonica (source of genistein). * Diagnosis of type 2 diabetes (these patients are followed in a separate Diabetes Clinic). * Current use of medications that may confound study outcomes, including: * GLP-1 receptor agonists (e.g., Saxenda, Wegovy) * ADHD medications (e.g., Concerta, Vyvanse, Abilify) * Antipsychotic medications (e.g., Risperidone) * Currently pregnant, breastfeeding, or planning to become pregnant during the study period.

Treatments and study arms

genistein

Drug

Participants will receive genistein treatment (10-15 mg/kg/day with a maximum dose of 1500mg/day) for 3 months. From the 3-month- to 6-month follow-up, participants will receive a dose of 20-25 mg/kg/day (with a maximum dose of 1500mg/day). According to participant preference, Genistein will be provided as a capsule (250mg per capsule). For participants that are unable to swallow the capsule the capsule may be opened and the powder from the capsule can be mixed with a beverage or food. Interim clinical evaluations will occur at 3 and 6 months to assess, tolerability, adherence and efficacy.. Post-treatment assessment after a 3-month washout will occur at 9 months to determine delayed adverse effects and persistence of beneficial effects after genistein discontinuation.

Primary outcomes

Change in Body Mass Index (BMI) z-score6 months

To assess the impact of genistein on Body Mass Index (BMI) z-scores, calculated using the World Health Organization (WHO) growth reference standards for age and sex. Scale: WHO BMI-for-age z-score Score Range: Typically from approximately -3 to +5 Interpretation: Higher scores indicate greater degrees of obesity, and lower scores indicate improvement in weight status relative to age and sex norms.
