The purpose of this alcohol-interaction pilot study is to provide information on the effect
of mavoglurant on the pharmacokinetics of alcohol and on alcohol responses, including
stimulation, sedation, intoxication, body sway and physiological responses. The investigators
propose to test the effects of 200 mg mavoglurant versus placebo on alcohol related
responses. This is a between subjects double blind randomized design in which the
investigators plan to run 40 subjects to obtain 28 completers.
