A Double-Blind, Placebo-Controlled Trial of Anti-Aging, Pro-Autophagy Effects of Metformin in Adults With Prediabetes

• Status: Unknown status
• Trial end date: 2021-07-31

Summary

The goal of this pilot and feasibility study is to investigate the effects of a short course of metformin therapy on a surrogate marker of cellular senescence and autophagy among adult patients with prediabetes. The overall hypothesis is that metformin will have beneficial effects on longevity and quality of life by inducing autophagy downstream of activating adenosine monophosphate-activated protein kinase (AMPK) and inhibiting mechanistic target of rapamycin (mTOR) through potential effects of reduced inflammation, reduced degeneration of muscle and tendon tissue, antineoplastic effects, reduced obesity and hyperglycemia, preserved cardiovascular functions, and/or the prevention of neurodegeneration (such as age-associated dementia). This pilot study will address the following aim:

Demonstrate that metformin therapy will increase cellular autophagy as an inverse correlate of aging as measured by increases in Microtubule-associated protein 1A/1B-light chain 3 (LC3) scores.

Hypothesis 1: In addition to beneficial effects on glycemia, body weight, and body composition, metformin therapy exerts beneficial effects on surrogate measures of autophagy and aging.

Primary outcome: Increased levels of LC3 in leukocytes.
