Effects of Sabroxy® Supplementation on Insulin Resistance and Cognitive Function in Adults With Mild Cognitive Impairment and Insulin Resistance

Study 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.

Primary Outcome

Insulin resistance will be evaluated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), calculated from fasting glucose and fasting insulin levels. The objective is to determine the mean change in HOMA-IR from baseline to Week 8 between the Sabroxy® and placebo groups.
