Enhancing the Effects of Adolescent Alcohol Treatment With Atomoxetine

Overview

The primary objectives of this study are twofold. The first primary objective is to evaluate the feasibility, acceptability, and tolerability of atomoxetine (40 mg/day for 3 days then 80 mg/day thereafter) as compared to placebo for 6 weeks plus a psychosocial platform comprised of motivational enhancement therapy and cognitive behavioral therapy (MET-CBT) among adolescents (ages 14 to 19 years) with alcohol use disorder as confirmed by the Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition (DSM-5™). The second primary objective is to leverage a human laboratory paradigm and ecological momentary assessment (EMA) methods to evaluate the effects of atomoxetine on intermediate phenotypes associated with alcohol use and outcomes in clinical trials.

Detailed Description

This proof-of-concept study is a double-blind, randomized, placebo-controlled, parallel-group, single-site study designed to assess the feasibility, acceptability, and tolerability of atomoxetine for alcohol use disorder among adolescents ages 14 to 19 years. In addition, this project will test the effects of atomoxetine, as compared with placebo, on responses to in vivo alcohol cue exposure in the human laboratory setting. After obtaining consent/parent permission/assent, youth and, if younger than 18 years, their parent will complete a medical history interview to screen for eligibility. Youth will also be screened for eligibility. If eligible for the study, participants will be randomized in an approximate 1:1 ratio (targeting 21 participants per group – 42 participants total) to either atomoxetine or placebo for 6 weeks. Atomoxetine will be dosed at 40 mg/day for three days then increased to the maintenance dose of 80 mg (active) taken orally once daily (QD) for an additional 5.5 weeks. Participants randomized to the placebo condition will be given an equal number of visually matched capsules. Participants will be seen in the clinic at the in-person screening appointment, the randomization/baseline session, and at 8 other times during the study. Three follow-up telephone interviews will occur at 2 weeks and three and six months after the last in-clinic visit. At the randomization/baseline visit and after 4 weeks of investigational product administration (i.e., Study Week 7), participants will undergo a human laboratory paradigm (i.e., alcohol cue reactivity assessment). In addition, participants will complete EMA on a smartphone throughout the day in their daily lives.

Interventions

  • Drug: Atomoxetine
    • Participants randomized to receive the study medication, atomoxetine (brand name: Straterra) for 6-weeks (40 mg/day for 3 days then 80 mg/day thereafter). A comparator group will receive placebo (sugar pills).
  • Drug: Placebo
    • Matching placebo (sugar pill)

Arms, Groups and Cohorts

  • Experimental: Atomoxetine
    • Atomoxetine (40 mg/day for 3 days then 80 mg/day thereafter) during a 6-week medication trial
  • Placebo Comparator: Placebo
    • Identical matching placebo capsules

Clinical Trial Outcome Measures

Primary Measures

  • Completion rates
    • Time Frame: 6-week active treatment phase
    • Percentage of youth who complete the active medication phase will determine feasibility.
  • Acceptability of the study medication
    • Time Frame: 6-week active treatment phase
    • Study withdrawal and the Client Satisfaction Questionnaire (CSQ-8), which ranges in scores from 8-32 (higher scores indicates higher satisfaction), will determine acceptability.

Secondary Measures

  • Alcohol Craving
    • Time Frame: 6-week active treatment phase
    • The primary measure of alcohol craving will be the following single-item: How strong is your craving to drink alcohol? Scores range from 0 (None) to 20 (Extremely Strong).
