Alcohol Drinking
Conditions
Brief summary
The purpose of this study is to evaluate the effects of the study medication, saracatinib/AZD0530 (placebo or 125 mg/day) on alcohol drinking behavior in a laboratory setting in which participants are given an initial drink of alcohol followed by the choice to drink up to 12 more drinks over a three-hour period. The investigators hypothesize that saracatinib will reduce craving and number of drinks consumed prior to and after exposure to the initial drink of alcohol and during the three hour drinking period.
Interventions
Saracatinib 125 mg once per day for 8 days
Placebo once per day for 8 days

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in the Number of Drinks Consumed From Baseline to Day 8 (Minus Baseline) | Baseline and Day 8 | Change in the number of standard drinks consumed at the drinking session (ADP 2) after taking study medication minus the number of standard drinks consumed at baseline (ADP 1). |
| Craving-Baseline Adjusted Total Area Under the Curve (AUC) During the Drinking Session Using the YCS | Baseline and Day 7 | Craving for alcohol based on Yale Craving Scale (YCS), scores ranging from 0-112 mm on a visual analog scale, with higher measurements indicating higher craving. The baseline-adjusted craving is change score from baseline at Day 7. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Curve (AUC) During the Drinking Session Using the Stimulation Responses to Alcohol (BAES) | Day 8 Adlib | Biphasic Alcohol Effects Scale (BAES) scores will be used to assess stimulation. The scale ranges from 0-70, with a higher score indicating more sedated. |
| Area Under the Curve (AUC) During the Drinking Session Using the Sedation Responses to Alcohol (BAES) | Day 8 Adlib | Biphasic Alcohol Effects Scale (BAES) scores will be used to assess sedation. The scale ranges from 0-70, with a higher score indicating more sedated. |
