Study Details

Brief summary:

The goal of this clinical trial is to identify sex-specific biomarkers that confer greater susceptibility for Alcohol Use Disorder (AUD) and differentiate how treatment response varies by sex in people with Alcohol Use Disorder.

The main questions it aims to answer are:

  • How does trauma affect emotion regulation, inflammation, and limbic function, and what are the sex-dependent effects of NTX (Naltrexone) on these aspects?
  • What is the mechanism of Naltrexone (NTX), and how does it potentially moderate reductions in alcohol use through changes in or interactions between emotion regulation, inflammation, or limbic system function?

Participants will

  • Be consented and will undergo comprehensive screening for eligibility criteria
  • Complete behavioral assessments and neuropsychological assessments, as well as neurocognitive assessments and neuroimaging measures
  • Provide urine samples for a urine drug screen (UDS) and urine pregnancy test (for women), and have blood and a cheek swab collected and stored in the repository
  • Take a study drug once daily for 12 weeks and track drug usage and effects in a study journal
  • Undergo weekly assessment calls and bi-weekly medical follow-up safety exams

Researchers will compare naltrexone to placebo in AUD to see if naltrexone is effective in reducing alcohol cravings and promoting abstinence.

Researchers will also compare baseline measures between AUD and Healthy Controls.

Interventions and Outcome Measures

Arms

experimental: Alcohol Use Disorder (AUD)

Drug: Naltrexone Half of the study participants with AUD will take an oral tablet of 50 mg naltrexone once daily for one week followed by 11 weeks of 100 mg naltrexone orally, once daily.

Drug: Placebo oral tablet The other half of study participants will receive an identical looking placebo in tablet form and take the medication using an identical schedule as the real drug.

Drug type will be randomized.

no intervention: Healthy Controls

Baseline measures will be taken but controls will not continue to the drug trial.

Interventions

Naltrexone

12-week randomized double blinded placebo-controlled drug trial titrating drug/placebo dose after 1 week.

Primary outcome measure

  • Change from baseline in alcohol use (number of drinking days, amount used per day) [ Time Frame: Baseline and Week 12 ]
  • Changes from baseline in peripheral immune biomarkers associated with inflammation [ Time Frame: Baseline and Week 12 ]
  • Changes in limbic functional connectivity [ Time Frame: Baseline and Week 12 ]
  • Changes from baseline in BOLD signal brain activation during an emotion regulation fMRI task [ Time Frame: Baseline and Week 12 ]
  • Changes from baseline in emotion regulation assessed with the Difficulty in Emotion Regulation Scale (DERS) [ Time Frame: Baseline and Week 12 ]
  • Changes from baseline in emotion regulation assessed with the Cognitive Emotion Regulation Questionnaire (CERQ) [ Time Frame: Baseline and Week 12 ]
