About this trial

This is an interventional other trial for Alcohol Use Disorder focused on measuring Ethanol, Alcohol, Self administration, BP1.3656B, Alcohol Use Disorder, Alcoholism, Alcohol Drinking, Drinking Behavior, Alcohol-Related Disorders, Substance-Related Disorders, Chemically-Induced Disorders, Mental Disorders

Eligibility Criteria

19 Years - 45 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Willingness to take study medication and participate in laboratory sessions requiring alcohol administration
  • Able to give written informed consent
  • Certified as healthy by a comprehensive clinical assessment. Alanine transaminase (ALT) and aspartate aminotransferase (AST) levels should not be more than 1.2 times normal

Exclusion Criteria:

Arm Description

Participants will receive BP1.3656 in tablet form once daily at a dose of 30 µg/day for the first 4 days, followed by 60 µg/day for the remaining 10 days. If the highest dose is not tolerated, it will be lowered to 30 µg.

Secondary Outcome Measures

Subjective effects of alcohol during free-access and progressive ratio self-administration sessions while taking study medication (BP1.3656), as measured by the Biphasic Alcohol Effects Scale (0-10 scoring)
Two subscales (stimulant and sedative) with a 0-10 scoring where higher scores for stimulant subscale indicate increased stimulated effects from alcohol, while higher scores for sedative subscale indicate more sedated effects from alcohol.
Subjective effects of alcohol (maximum reported stimulation and sedation from alcohol) during free-access and progressive ratio self-administration sessions while taking placebo, as measured by the Biphasic Alcohol Effects Scale (0-10 scoring)
Two subscales (stimulant and sedative) with a 0-10 scoring where higher scores for stimulant subscale indicate increased stimulation, while higher scores for sedative subscale indicate more sedated effects from alcohol.
Self-reported craving after a priming dose of alcohol during free-access and progressive ratio self-administration sessions while taking BP1.3656, as measured by the Alcohol Urge Questionnaire (1-7 scoring)
8 statements with score options ranging from Score of 1 = Strongly disagree to Score of 7 = Strongly Agree. Higher scores reflect greater craving.

8 statements with score options ranging from Score of 1 = Strongly disagree to Score of 7 = Strongly Agree. Higher scores reflect greater craving.
Safety and tolerability of BP1.3656
Side effects of BP1.3656 will be assessed with the Systematic Assessment for Treatment Emergent Effects questionnaire (not reporting score on a scale) and the Pittsburgh Sleep Quality Index (19 items with 0-3 scoring, where higher scores indicate worse sleep quality).

5. Study Description

Brief Summary
The current study will determine whether a novel pharmacotherapy, BP1. 3656, affects laboratory alcohol self-administration in participants with alcohol use disorder (AUD).
Detailed Description
The current study employs BP1.3656, a novel investigational compound with a track record for safety and tolerability in phase I clinical trials. When administered to mice, BP1.3656 was associated with increased metabolism of histamine and elevated brain dopamine and acetylcholine, suggestive of utility in psychiatric disorders including Alcohol Use Disorder (AUD). This study is a Phase II laboratory-based trial of BP1 .3656 for AUD. 40 non-treatment seeking participants with AUD will be recruited. Participants will be randomly assigned to intervention with BP1 .3656 or placebo in a within-subject, crossover design. During each intervention period, outcome measures relating to alcohol motivation and self-administration will be assessed in the laboratory. It is hypothesized that relative to placebo, alcohol self-administration will be decreased by BP1 .3656.

Crossover Assignment
Model Description
This will be a within-subjects, counterbalanced, crossover trial with a washout period. Participants will receive either placebo or the interventional drug BP1.3656 during the initial 14-day phase of the study and receive the other intervention during the second 14-day phase of the study. The washout period will last a minimum of 14 days. Participants will come in to the laboratory on two separate days near the end of each intervention phase to complete alcohol self-administration sessions.
