Effect of GET73 on MRS Measures of Central Glutamate and GABA in Individuals With Alcohol Use Disorder

Summary

This study is aimed at examining whether GET73 modulates the indices of central glutamate and γ-aminobutyric acid (GABA) levels in recently abstinent subjects that meet Alcohol Use Disorder (AUD) criteria, as measured by proton nuclear magnetic resonance spectroscopy (¹H-MRS), in order to provide a human translation of the findings demonstrated in different preclinical models, both in vitro and in vivo. In addition, the study will examine the effects of GET73 on alcohol cue induced brain activation by using a well-established blood-oxygen-level-dependent (BOLD) functional magnetic resonance (fMRI) paradigm in the same individuals. In summary, the study should provide important information on (i) the potential mechanism of action of GET73, (ii) on the brain mechanisms that would support its potential use for reduction in craving and drinking in AUD patients, and (iii) expand data on its safe use as a medication in heavy drinking individuals.
