NCT06027554

Brief Summary

The goal of this clinical trial is to test the effects of MitoQ supplementation in older adults and frail older adults with physical dysfunction and/or cognitive dysfunction. The main question\[s\] it aims to answer are:

  • To compare vascular function, oxidative stress levels, and physical and cognitive function among older adults and frail older adults with physical and cognitive dysfunction
  • To determine whether MitoQ supplementation has the potential to improve vascular function in central and cerebral vessels
  • To determine whether MitoQ supplementation can enhance physical and cognitive capabilities.

Outcome Measures

Primary Outcomes (5)

  • Change in Vascular Endothelial Function

    Assess Femoral artery through Passive Leg Movement and Brachial artery flow-mediated dilation (% \[relative\] and mm \[absolute\])

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

  • Change in Cerebrovascular Function

    Utilize ultrasound to measure a change in blood flow velocity in response to a breathing test (cm/s)

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

  • Change in NIH Tool Box Composite

    NIH Toolbox Cognitive Battery is a multidimensional set of brief measures assessing cognitive (as well as emotional, motor and sensory) function. There is no score range, but mean score is 100 with standard deviation 15. A score at or near 100 indicates average ability compared with others. Scores around 115 suggest above-average ability. Scores around 130 suggest superior ability (in the top 2 percent nationally). A score around 85 suggests below-average ability. A score in the range of 70 or below suggests significant impairment.

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

  • Change in walking speed

    Gait speed calculated from 10 meter walk test. Only the 6 intermediate meters are recorded. Time is recorded by a manual chronometer. 3 records are done, mean time is calculated. Mean time is divided by 6 to obtain mean gait speed

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

  • Sensitivity of a Montreal Cognitive Assessment score

    sensitivity of a Montreal Cognitive Assessment score \< 26 to detect cognitive impairment defined as an abnormal result in at least one of the following tests : Test of Attentional Performance of Zimmermann and and Fimm (\< 5th percentile in at least one of the subscales) ; Wechsler Adult Intelligence Scale 4th version digit span (standard score ≤ 5) ; Wechsler memory scale III, spatial span (standard score ≤ 5) ; Wisconsin Card Scoring Test, GREFEX version (number of categories ≤ 5th percentile or if the number of perseverations is ≥ 95th percentile) Wechsler Adult Intelligence Scale 4th version block design (standard score ≤ 5) ; Six elements test GREFEX version (rank score ≤ 5th percentile ); free and cued selective reminding test, 16 items, B version (Z-score ≤ -1,65 in at least one of the subscales)

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

Secondary Outcomes (2)

  • Change in Mitochondrial Function measured in peripheral blood mononuclear cells (PBMCs)

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

  • Change in Oxidative Stress measured in peripheral blood mononuclear cells (PBMCs) by O2flux in pmol/second/cell numbers

    4 visits : Baseline, 12 weeks (MitoQ or Placebo), 8 weeks washout, 12 weeks (MitoQ or Placebo)

Eligibility Criteria

Age65 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • men and women aged 65-80 with a slow gait speed (0.4m/s based on a 4m walk) and/or mild cognitive impairment.
  • good cardiovascular health (not taking any blood pressure/flow/metabolism altering medications)

You may not qualify if:

  • A vaccination in past two weeks
  • Recent acute infection three weeks prior to enrollment
  • Known immunodeficiency (including HIV infection, primary immunodeficiency, any history of chemotherapy or radiotherapy
