Official title
Guanfacine for Alcohol Use Disorder (AUD): a Telehealth Approach
Overview
The investigators assess whether guanfacine extended release (GXR; 3mg/d) compared with placebo (PBO) will attenuate drinking and drinking-related factors in N=200 men and women with Alcohol Use Disorder (AUD) across 12-weeks.
Detailed description
This is a study to examine the efficacy of guanfacine extended release (GXR) (3mg/d) compared with placebo (PBO) in reducing drinking in N=200 men and women with Alcohol Use Disorder (AUD). The study will be conducted across two sites for 12-weeks. Indiana University will be the primary site and Rutgers University, the secondary site. Participants at both sites will be randomized to either GXR (3mg/d) or placebo (PBO), and titrated to full dose over a three week period. After remaining at full dose for 7 weeks a two week schedule will be used to taper participants off the medication. During the study the investigators will collect brief reports throughout the day and evening of drinking severity, stress, craving, mood, arousal, anxiety, and emotion regulation at weeks 1 and 2 (baseline) and weeks 5 and 6 (steady state). Additionally, blood alcohol concentration (BAC) levels will be collected three times per day for the full 12-weeks. Daily encrypted video recordings will be used to monitor medication compliance, and participants will also take part in twice weekly remote visits to assess safety, vitals, collect urines, monitor alcohol use, and receive weekly Medical Management. It is anticipated that guanfacine will demonstrate greater efficacy in women compared to men with AUD.
