Tocotrienol Supplementa as A Senolytic Agent in Middle-aged Adults
A Randomized, Double-Blind, Placebo-Controlled Phase 2 Clinical Trial Evaluating Tocotrienol-Rich Fraction as a Senolytic Agent in Middle-Aged Adults
The goal of this clinical trial is to determine whether tocotrienol works as a senolytic agent to delay age-related biological changes in middle-aged adults. The study will also evaluate the safety of tocotrienol supplementation. The main questions it aims to answer are:
Does tocotrienol reduce markers of cellular senescence, inflammation, oxidative stress, and mitochondrial dysfunction?
What health changes or medical issues occur in participants taking tocotrienol?
Researchers will compare tocotrienol-rich fraction to a placebo (a look-alike capsule with no active ingredient) to determine whether tocotrienol is effective in modulating aging-related pathways.
Participants will:
Take tocotrienol (200 mg/day) or a placebo daily for 6 months
Attend study visits at baseline, 3 months, and 6 months for clinical assessments and laboratory tests
Undergo blood sampling and health evaluations, including measures of senescence-associated secretory phenotype (SASP), inflammation, oxidative stress, mitochondrial function, vascular health, skin status, cognitive function, body composition, and bone mineral density.
Complete questionnaires related to diet throughout the study period
This study aims to provide clinical evidence on the potential of tocotrienol as a senolytic intervention for promoting healthy aging and reducing the risk of age-related diseases.

Recall memory function
Časové okno: Baseline and Month 6

The Rey Auditory Verbal Learning Test (RAVLT) will be utilized. the RAVLT includes two distinct word lists (A and B). Participants will recall the items from list A over five trials (Memory A1 to A5). Following this, an interference list (list B), comprising 15 unrelated nouns, will be introduced, and participants will attempt to recall as many words as possible from it. Subsequently, participants will be asked to recall the words from list A (Delayed recall/memory A6) without the examiner repeating the list. The number of correctly recalled words for each trial will be totaled to generate a score. Total Learning Score (Sum of Trials A1-A5) to indicate normal performance: 45-65, Mild Cognitive impairment: 30-45, dementia: below 30. For delayed recall score (M6), to indicate normal performance: ≥8-12 words recalled, Mild Cognitive Impairment: 4-7 words recalled, and dementia: ≤3 words recalled |
