Official title

A Proof of Concept Trial of a Sirtuin-NAD Activator in Alzheimer's Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary objectives are to: 1. To determine whether MIB-626, after its daily oral administration, penetrates the blood-brain barrier in humans by measuring the cerebrospinal fluid (CSF) concentrations of MIB-626 and its key metabolites, nicotinamide (NAM), NR, 2-PY, and MeNAM at baseline and on day 90 at steady state. 2. To evaluate whether oral MIB-626 administration engages the sirtuin-NAD pathway by determining the abundance of NAD (a SIRT1 substrate) in the brain using ultra-high field 7T magnetic resonance spectroscopy and in peripheral blood mononuclear cells using a validated LC-MS/MS assay. 3. To determine whether MIB-626 alters the circulating biomarkers of aging that the geroscience experts have recommended (HbA1C, IGF1, T3, IL6, TNF, and urinary F2-isoprostane).
