Effects of Sabroxy® Supplementation on Insulin Resistance and Cognitive Function in Adults With Mild Cognitive Impairment and Insulin Resistance
Trial Parameters
Brief Summary
This randomized, double-blind, placebo-controlled, 8-week clinical trial is designed to evaluate the effects of Sabroxy®, a standardized extract of Oroxylum indicum bark, on insulin resistance and cognitive function in adults with mild cognitive impairment and insulin resistance. A total of 120 participants (men and women, aged 40-80 years) who are non-smokers, with fasting glucose levels between 100-135 mg/dL, HOMA-IR value ≥ 2.0 to \< 4.0, and a Montreal Cognitive Assessment (MoCA) score below 26, will be enrolled. Eligible participants will be randomized (1:1) to receive either Sabroxy® (250 mg with 5 mg BioPerine®) or placebo, administered orally once daily for 8 weeks. The primary endpoint is the change in insulin resistance from baseline to Week 8, assessed using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). The secondary endpoints include changes in: Cognitive performance, assessed using the Immediate Word Recall, Numeric Working Memory, Cognitive Failures Questionnaire (CFQ), and Montreal Cognitive Assessment (MoCA). Biomarkers of metabolic and neuronal function, including Brain-Derived Neurotrophic Factor (BDNF), high-sensitivity C-reactive protein (hs-CRP), fasting insulin, fasting glucose, and phosphorylated tau/amyloid beta (p-Tau/Aβ) ratio. Safety will be assessed through adverse event monitoring, vital signs, and routine clinical laboratory tests. The study will be conducted at a single site, San Francisco Research Institute (USA), in compliance with the Declaration of Helsinki, ICH-GCP guidelines, and 21 CFR Part 312 (where applicable). This study seeks to generate clinical evidence supporting the potential of Sabroxy® supplementation to improve glucose tolerance, reduce inflammation, and enhance cognitive function in individuals with early metabolic and neurocognitive dysfunctions.
