Targeting Aging and Promoting Longevity With Exogenous Nucleotides (TALENTs)

Aging Clinical Trial

Official title: A Randomized Controlled Trial Study To Evaluated the Effect of Exogenous Nucleotides as an Anti-ageing Supplement in Older Adults (60-70 Years)

Status Completed

Clinical Trial Summary

To investigate the effects of dietary nucleotides (NTs) as an anti-aging supplement, a clinical trial is carried as a randomized, double-blind, parallel design, placebo-controlled. A total of 120 subjects will be enrolled in the study, and they shall be randomly distributed between the two arms, NTs-treated, and placebo-control. They would be given several measurements, including physical examination, questionnaire survey, clinical and aging-related biomarkers tests at 0 (baseline), 2, and 4 months during the RCT.

Clinical Trial Description

To explore the anti-aging effects of NTs and the regulation of aging-related diseases, this study plans to recruit 120 people as subjects and conduct randomized controlled trials with NTs as an intervention for 4 months. Based on computer-generated random numbers, participants who meet the inclusion criteria are randomly assigned equally to two groups: placebo control and nucleotide intervention groups. In this study, the specific nucleotide composition is 5'-AMP、5'-CMP、5'-GMPNa2、5'-UMPNa2 prepared according to the ratio of 16:41:19:24, which is consistent with the ratio in breast milk and meets the requirements of national infant formula addition and special medical food formula. The dose of 1.2 g/day used is currently approved as the ingredient dose of nucleotides in conventional commercially available health food products. At the 0、2 and 4 months of the study, comprehensive geriatric health assessment, aging biomarker testing and biological sample collection will be conducted. Among them, the comprehensive evaluation of elderly health status is carried out by physical examination and questionnaire survey, including physical health, physiological function, quality of life, cognitive function, psychosocial health, and other aspects of information. The physical examination involves both physical assessment and functional assessment, including body composition, neck circumference, waist circumference, hip circumference, middle arm circumference, calf circumference, BMR, grip strength, six-minute walk, intima-media thickness, subcutaneous AGEs, and spirometry. The scale includes health status, nutritional status, cognitive status, physical activity, and dietary status. Blood samples were used to detect the safety and senescence-related indicators of the subjects. The index system covers four modules and seventeen dimensions, including blood routine, blood biochemistry, inflammatory factors, immune antibodies, T lymphocyte subtypes, oxidative stress level, cancer markers, leukocyte telomere length, DNA methylation, γ-H2A. Blood samples are sequenced simultaneously for gene and transcriptome sequencing. Fecal samples are collected for metagenomic sequencing of intestinal flora. ;
