Summary
The purpose of this study is to evaluate the safety and efficacy of dutasteride in reducing drinking and heavy drinking in men and women with alcohol use disorder. The investigators hypothesize that dutasteride 1 mg per day will be well tolerated in this patient population and that, compared to placebo treatment, dutasteride will result in a greater reduction in drinks per week and in the frequency of heavy drinking days.
Description
Heavy drinking remains a significant public health problem and is frequently under treated. Although several medications have been shown to help patients stop or reduce drinking, additional medication options are needed as there is considerable variability in effectiveness or tolerability of existing medications for individual patients. Additionally, identification of individual subject level predictors of efficacy are needed to better personalize pharmacotherapy treatment recommendations. This study will seek to replicate and extend our results showing efficacy of a novel medication dutasteride for reducing drinking and will examine potential easily measured predictors of response.
Dutasteride is a widely prescribed medication for benign prostatic hypertrophy and androgenic hair loss that also modulates the elimination of cortisol and the production of some neuroactive steroids. Changes in the regulation of cortisol and neuroactive steroids have each been suggested as factors which may contribute to the maintenance of alcohol dependence. Data from a recently completed first randomized placebo controlled trial of dutasteride for AUD in a sample of male drinkers, indicates that dutasteride is well tolerated in alcoholics and has efficacy in helping subjects reduce drinking. Additionally, results indicate that dutasteride may be particularly helpful for patients who drink to cope with anxiety and negative emotions, a group of patients with poor response to other treatments.
This 24-week treatment study will use an innovative randomized placebo controlled step therapy design to examine the safety and efficacy of dutasteride to reduce drinking by treatment seeking women and men with hazardous levels of alcohol use. At 12-weeks placebo non-responders will transition to dutasteride and dutasteride non-responders will transition to naltrexone, an FDA approved medication with demonstrated efficacy for reducing heavy drinking. 12-week responders (reduction in drinks/week of 60% or greater compared with screening) will continue for an additional 12-weeks on their initial study medication assignment (dutasteride or placebo).
Additionally, the investigators will examine several baseline measures as predictors of dutasteride efficacy, including drinking to cope, anxiety, adverse child events, and perceived life stress as well as stress resilient vs. reactive genotypes of FKBP5 a chaperone protein involved in regulation of glucocorticoid, androgen and progesterone receptor function.
