Mavoglurant in Alcohol Drinking
- Study HIC#:2000021703
- Last Updated:04/21/2023
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 14 subjects to obtain 10 completers.

Trial Purpose and Description
The following specific aims will be tested: Aim: To evaluate the safety and tolerability of mavoglurant when used in combination with a moderate dose of alcohol in healthy social drinkers. Specific Aim 1: To evaluate the effect of mavoglurant on blood chemistries, urine toxicology and physiological safety measures before and after alcohol administration. Specific Aim 2: To evaluate the interactions of alcohol and mavoglurant on blood alcohol levels and mavoglurant levels. Exploratory Aim: To explore the effects of mavoglurant on alcohol responses, including stimulation, sedation, intoxication, and cognitive/motor performance.
