Official title: The NADage Study: A Randomized Double-blind Trial of NAD Replenishment Therapy on Aging

Status Not yet recruiting

Clinical Trial Summary

This clinical study, designed as a double-blind, randomized, placebo-controlled trial, aims to investigate the potential of nicotinamide riboside (NR) to decelerate functional decline in the elderly frail population. In animal studies, NR, which is converted to nicotinamide adenine dinucleotide (NAD), has shown potential as a neuroprotective agent, with indications of protection against amyotrophic lateral sclerosis (ALS), Alzheimer's dementia, and Parkinson's disease. Furthermore, aging is commonly associated with decreased tissue NAD levels, a phenomenon linked to premature aging and a spectrum of age-related disorders, including cardiovascular diseases and cancers. Existing preclinical and clinical research highlights the promise of NAD replenishment through enhanced DNA repair, sirtuin activity, and improved mitochondrial function. The research center has conducted two phase II clinical trials on NR for Parkinson's disease (NAD-PARK and NR-SAFE), administering up to 3000 mg of NR daily. These trials have shown promising results, indicating NR's potential as a treatment that may alter the course of the disease and possibly as neuroprotective treatment in Parkinson's disease. The NAD age trial primarily aims to determine: - The efficacy of NAD therapy in improving clinical symptoms of frailty, evaluated through standardized physical and cognitive function tests. - The safety of administering 2000 mg NR daily in an elderly frail population. The study will include 100 individuals, classified as frail based on the Fried Frailty Phenotype. Participants will be randomly assigned to receive either 2000 mg of NR daily or a placebo. Over a 52-week period, participants will undergo: - Clinical evaluations, including actigraphy and questionnaires. - Cognitive assessments. - Bio sampling. - Magnetic resonance imaging (MRI). - Positron emission tomography (FDG-PET) scanning. The outcomes of this study could potentially demonstrate that NR effectively reduces signs of frailty, offering considerable advantages to the individuals affected, their families, and society as a whole.

Clinical Trial Description

This study aims to administer 2000 mg of nicotinamide riboside (NR) daily to explore its effects on brain and body metabolism in an elderly, frail population. The research design is a single-center, double-blind, randomized, placebo-controlled approach. Participants will be evenly randomized into two groups in a 1:1 ratio: one to receive a placebo and the other to receive 2000 mg of NR daily. The intervention will last for 52 weeks, during which primary and secondary outcomes will be assessed across and within both groups. The primary objective is to evaluate the impact of NR on gait speed by comparing the treatment group with the placebo group. Secondary objectives include assessing the safety and tolerability of NR, as well as its clinical effects on physical and cognitive functions, using standardized tests. Furthermore, exploratory objectives will be pursued using various methods such as questionnaires, biosampling, actigraphy, and brain scans. These scans will include 31P-MR-spectrometry to analyze NAD levels in the brain and FDG-PET to assess metabolic network activity. The study will include 100 frail individuals who have provided informed consent. Biological samples to be collected include blood/serum, blood cells, urine, and fecal samples. Given the previously demonstrated potential of NR in reducing symptoms of Parkinson's disease, this study seeks to expand knowledge of its effects on an elderly, frail population without neurodegenerative disorders. If NR is found to be effective in improving measures of frailty, it could significantly impact societal health and economy, especially considering the extensive socio-economic challenges associated with frailty. ;
