About this study

Official title: A Randomized, Double-Blind Placebo Controlled Study to Assess the Effects of an Oroxylum Indicum Extract (Sabroxy™) on Cognitive Function in Adults With Self-reported, Mild Cognitive Impairmentx

This study is testing whether Sabroxy™ (Oroxylum indicum extract) can improve memory and thinking in older adults who report mild problems with their cognition. The study will also measure levels of a protein in the blood called BDNF (Brain-Derived Neurotrophic Factor), which is linked to brain health.

The main questions are:

Read more

Does taking Sabroxy™ improve memory, focus, and overall cognitive performance compared to placebo (a capsule that looks the same but has no active ingredient)?

Does Sabroxy™ increase levels of BDNF in the blood?

About 80 participants between the ages of 60 and 85 will take part. All participants will be randomly assigned to receive either Sabroxy™ or placebo twice daily for 12 weeks. Neither the participants nor the researchers will know which group they are in (double-blind design).

During the study, participants will:

Take one capsule twice daily after meals.

Complete computerized cognitive tests (COMPASS), interviews with the Montreal Cognitive Assessment (MoCA), and self-assessment questionnaires on memory and thinking.

Provide blood samples to measure BDNF.

Attend 4 clinic visits (baseline, week 4, week 8, and week 12).

Keep a daily diary to track product use and study compliance.

The goal is to see whether Sabroxy™ can safely and effectively support cognitive health in older adults with mild memory concerns.

Read the detailed description

This is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effects of Sabroxy™ (Oroxylum indicum extract) on cognitive function in adults with self-reported, mild cognitive impairment.

Approximately 84 participants will be recruited, with a goal of 80 completing the study. Participants will be between 60-85 years old, in generally good health, and living independently. Eligible participants must report concerns about their memory or thinking, confirmed with a screening test (MoCA).

After screening and baseline assessments, participants will be randomly assigned to receive either Sabroxy™ or placebo. Both products will look identical to ensure blinding. Participants will take one capsule twice daily, after meals, for 12 weeks.

The study assessments include:

Computerized Mental Performance Assessment (COMPASS): tests of memory, attention, and reaction time.

Montreal Cognitive Assessment (MoCA): an interviewer-administered cognitive test.

Mild Cognitive Impairment Questionnaire: a self-reported measure of memory and thinking concerns.

Blood samples: to measure Brain-Derived Neurotrophic Factor (BDNF) at baseline and week 12.

Daily diaries and capsule counts: to monitor adherence.

The visit schedule is as follows:

Baseline (Visit 1): Screening, informed consent, eligibility check, cognitive testing, blood draw, product distribution, and diary instructions.

Week 4 (Visit 2): Product count, diary review, questionnaire.

Week 8 (Visit 3): Product count, diary review, questionnaire.

Week 12 (Visit 4): Cognitive testing, blood draw, questionnaire, product return, diary review.

Statistical analyses will compare changes in cognitive performance and BDNF levels between the Sabroxy™ and placebo groups.

This study will provide important information about the potential of Sabroxy™ to support memory and brain health in older adults with mild cognitive concerns.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sabroxy™ (Oroxylum indicum extract)Dietary supplement

    Also called Oroxylum indicum extract, Sabroxy™

    Sabroxy™ is a standardized extract derived from the bark of Oroxylum indicum. In this study, participants will receive Sabroxy™ in capsule form. Each capsule contains a fixed dose of the extract and will be administered orally at a regimen of one capsule twice daily after meals for 12 weeks. The supplement is provided in visually identical containers to maintain blinding and is compared to a placebo control. The intervention is designed to evaluate potential improvements in cognitive function, including memory, attention, and executive performance, as well as effects on circulating Brain-Derived Neurotrophic Factor (BDNF) levels.

  • PlaceboOther

    Also called Inactive capsule, Look-alike capsule

    The placebo is an inert capsule formulated to be visually identical to the Sabroxy™ capsules in size, shape, color, and packaging. It contains inactive ingredients only, with no active botanical extract. The placebo will be administered orally at the same regimen as the active intervention: one capsule taken twice daily after meals for 12 weeks. The use of a placebo ensures blinding of participants and study staff, allowing accurate comparison of cognitive and biomarker outcomes between groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Montreal Cognitive Assessment (MoCA) total score

    The Montreal Cognitive Assessment (MoCA) is a 30-point interviewer-administered test assessing memory, attention, visuospatial ability, language, and executive function. Scores range from 0 to 30, with higher scores indicating better cognitive function (a score ≥26 is generally considered normal). The mean change from baseline to Week 12 will be compared between the Sabroxy™ and placebo groups.

    Measured: Baseline and Week 12

  2. Change in COMPASS accuracy composite (percent correct)

    The Computerized Mental Performance Assessment System (COMPASS) provides accuracy scores (% correct) across cognitive subtests (e.g., memory recognition, working memory). Composite accuracy is reported as the mean percentage correct across prespecified subtests. Scores range from 0% to 100%, with higher percentages indicating better accuracy/performance. The mean change from baseline to Week 12 will be compared between the Sabroxy™ and placebo groups.

    Measured: Baseline and Week 12

  3. Change in COMPASS mean reaction time (milliseconds)

    The Computerized Mental Performance Assessment System (COMPASS) measures reaction time in milliseconds (ms) across attention and response tasks. Reaction time is a continuous measure (theoretical range: 0 ms to no fixed upper limit). Lower values indicate faster and therefore better performance. Results will be reported as mean milliseconds and mean change from baseline.

    Measured: Baseline and Week 12

Secondary outcomes (8)
  1. Change in Mild Cognitive Impairment Questionnaire (self-reported cognitive function) total score

    The Mild Cognitive Impairment Questionnaire is a self-report tool where participants rate memory and thinking difficulties over the past 4 weeks. Responses are recorded on a 5-point Likert scale (1 = Never, 5 = Always) across multiple items. Scores are summed to generate a total score, with the minimum possible score = [lowest possible total, e.g., number of items × 1] and maximum = [number of items × 5]. Higher scores indicate worse self-reported cognitive function (greater impairment). Mean change from baseline to Weeks 4, 8, and 12 will be compared between Sabroxy™ and placebo groups.

    Measured: Baseline, Week 4, Week 8, Week 12

  2. Change in Brain-Derived Neurotrophic Factor (BDNF) Levels

    Blood samples will be collected to measure serum BDNF levels. Mean change from baseline to Week 12 will be compared between Sabroxy™ and placebo groups.

    Measured: Baseline and Week 12

  3. Compliance with investigational product by capsule count

    Compliance will be assessed by counting returned capsules at each visit. Compliance percentage will be calculated as:

    (number of capsules actually taken ÷ number of capsules expected to be taken) × 100(number of capsules actually taken ÷ number of capsules expected to be taken) × 100(number of capsules actually taken ÷ number of capsules expected to be taken)×100. The mean compliance percentage will be compared across groups. Unit of Measure: Percent (%)

    Measured: Week 4, Week 8, Week 12

  4. Incidence of Treatment-Emergent Adverse Events (AEs)

    Safety will be assessed by recording all treatment-emergent adverse events reported or observed from baseline through Week 12. Results will be reported as the number and percentage of participants experiencing at least one AE.

    Measured: Baseline through Week 12

  5. Compliance with investigational product by daily diary review

    Compliance will also be assessed by reviewing participant daily diaries documenting capsule intake. Compliance percentage will be calculated as:

    (number of days capsule intake recorded ÷ number of days expected)×100(number of days capsule intake recorded ÷ number of days expected) × 100(number of days capsule intake recorded ÷ number of days expected)×100.

    The mean compliance percentage will be compared across groups. Unit of Measure: Percent (%)

    Measured: Week 4, Week 8, Week 12

  6. Incidence of Serious Adverse Events (SAEs)

    Serious adverse events will be recorded throughout the study. Results will be reported as the number and percentage of participants experiencing at least one SAE. Unit of Measure: Number of participants.

    Measured: Baseline through Week 12

  7. Incidence of Participant-Reported Side Effects

    Tolerability will be assessed through participant-reported side effects, captured via direct questioning and diary review. Results will be reported as the number and percentage of participants reporting at least one side effect. Unit of Measure: Number of participants.

    Measured: Baseline through Week 12

  8. Number of Discontinuations Due to Adverse Events

    The number of participants who discontinue the study due to adverse events will be recorded and compared between treatment groups.

    Unit of Measure: Number of participants

    Measured: Baseline through Week 12
