About this study

This study proposes to examine both the peripheral and central nervous system responses when light social drinkers and binge/heavy social drinkers are exposed to oral ethanol. The findings will provide a greater understanding of the brain mechanisms (cerebral blood flow and functional connectivity) underlying the association between stress, cortisol release, heart rate variability, alcohol craving, and alcohol stimulant and sedative effects. This knowledge could be significant in developing new therapies for the treatment of alcoholism.

Read the detailed description

This study was a single-blind, mixed Between Subjects and repeated measures across Alcohol and Placebo conditions in separate sessions in a 2 scan neuroimaging experiment. The two groups of participants were Moderate Social Drinkers and Binge/Heavy Social Drinkers, categorized on the basis of NIAA criteria for moderate non-binge and binge/heavy drinking. Subjects were randomly assigned to receive alcoholic or non-alcoholic beer in scanning condition 1 or condition 2. Before each scan, they were exposed to 3 12 Oz. alcoholic beer or 3 12 Oz. non-alcoholic beer via an Alcohol Taste Test (ATT) during which they were asked to taste the beers to determine if they were same or different. The order of the two conditions was counterbalanced and randomized across participants. Cerebral blood flow (CBF) was then measured using Arterial Spin Labeling. In addition to measuring the different effects of alcoholic beer vs. non-alcoholic beer on CBF, the investigators also measured subjective alcohol effects, alcohol craving, breath alcohol levels, cortisol, and ACTH. Statistical tests were performed to determine if these dependent measures were due to Group, Condition, or a Group x Condition interaction. Finally, the relationship between these variables and the amount of beer consumed at the second post-scan ATT was examined. The post-scan ATT only presented with the choice to drink non-alcoholic beer in order to more clearly predict behavioral motivation for alcohol from PreATT alcohol response in cortisol, CBF and subjective ratings. Data was obtained by research staff, nurse, and MRI technician who were blind to condition as were the subjects but PI and project director were not blind.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Blood Flow

    Blood flow is measured in ml/100 grams/minute. The interpretation is that blood flow to that area indicates that region of the brain is responding to the consumption of alcohol or alcohol cues. Change in blood flow will be calculated as the change (and slope) of measurements taken at 10, 20, 30 and 45 minutes during the procedure.

    Measured: End of Procedure (45 minutes)

  2. Change in Amount of drink consumed (alcohol or placebo)

    Amount of drink consumed (alcohol or placebo) during the Alcohol Taste Test (ATT)

    Measured: Pre-scan ATT and immediately Post scan ATT

Secondary outcomes (4)
  1. Changes in Alcohol Effects (BAES)

    Alcohol effects will be measured using the Biphasic Alcohol Effects Scale (BAES). The BAES is a 12 item questionnaire with a 12-120 range. The higher the total value (up to 120), the greater the measured effects of alcohol. The change in alcohol effects will be assessed with the taking the change (and slopes) of measurements at 45, 30 and 5 minutes prior to procedure and comparing it to measurements taken at 65, 95, 110, 125 minutes following the procedure.

    Measured: Post follow up to Procedure (125 minutes)

  2. Changes in Alcohol Effects (DEQ)

    Alcohol effects will be measured using the Drug Effects Questionnaire (DEQ). The DEQ consists of 5 questions with 5-25 total point distribution. The greater the total points, the greater the measured effect of alcohol. The change in alcohol effects will be assessed with the taking the change (and slopes) of measurements at 45, 30 and 5 minutes prior to procedure and comparing it to measurements taken at 65, 95, 110, 125 minutes following the procedure.

    Measured: Post follow up to Procedure (125 minutes)

  3. Changes in Alcohol Urges (AUQ)

    The urge to consume alcohol will be measured using the Alcohol Urge Questionnaire (AUQ). The AUQ consists of 8 questions 8-56 total point distribution. The greater the total points, the greater the measured urge to consume alcohol. The change in alcohol urge will be assessed with the taking the change (and slopes) of measurements at 45, 30 and 5 minutes prior to procedure and comparing it to measurements taken at 65, 95, 110, 125 minutes following the procedure.

    Measured: Post follow up to Procedure (125 minutes)

  4. Change in Cortisol

    The units for cortisol are micrograms/deciliter and the interpretation is that amount has been released into the blood stream from the HPA axis in response to alcohol or alcohol cues. Change in Cortisol will be calculated by taking the change (and slopes) of measurements at 45, 30 and 5 minutes prior to procedure and comparing it to measurements taken at 65, 95, 110, 125 minutes following the procedure.

    Measured: Post follow up to Procedure (125 minutes)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Alcoholic Beverage, Non-Alcoholic Beverage and Ethanol in people with Alcohol Abuse, run by Yale University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Blood Flow (time frame: End of Procedure (45 minutes)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2022.
