Trial Outcomes & Findings for Dutasteride Treatment for Reducing Heavy Drinking in AUD: Predictors of Efficacy (NCT NCT04098302)

NCT ID: NCT04098302

Last Updated: 2025-05-09

Results Overview

The number of heavy drinking days per week (i.e., four or more drinks in a day for women and five or more drinks in a day for men). The values listed in outcome table are the average HDD per week for the last 4 weeks (9-12) of phase 1 treatment. The generalized linear mixed model analysis considered all data from the ITT sample (75 dutasteride and 80 placebo participants)
