About this study
Official title: Glutamate-opioid Interactions in Alcohol Drinking Behaviors
The purpose of this study is to evaluate the combined effects of the study medications naltrexone and memantine on alcohol drinking behaviors.
Read the detailed description
Participants will be randomized to receive a combination of naltrexone/memantine over a one week period and then participate in a laboratory session. During this session, participants are given an initial drink of alcohol followed by the choice to drink up to 12 more drinks over a three-hour period. These medications are hypothesized to 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Drinks Consumed at Lab Session (Day 7)
Number of drinks consumed during the lab session (Day 7) after taking study medication, ranging from 0-12.
Measured: Day 7
Craving AUC: Adlib Drinking Phase
Craving for alcohol based on Alcohol Urge Questionnaire (AUQ, Bohn et al., 1995), which is an 8 item measurement of self-reported alcohol urges that has been shown to be strongly related to alcohol dependence severity. Each item is scored from 1 (strongly disagree) to 7 (strongly agree), with a higher score indicating higher craving. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Higher craving scores (ranging from 0-56) are indicated by larger log-transformed AUC.
Measured: 50-230 minutes after the priming drink during lab session
Stimulation Response to Alcohol at Lab Session
Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Higher stimulation scores (ranging from 0-70) are indicated by larger log-transformed AUC.
Measured: 50-230 minutes after the priming drink during lab session
Sedation Response to Alcohol at Lab Session
Brief Biphasic Alcohol Effects Scale-Sedation subscale (BAES; Martin et al., 1993), measuring sedation effects of alcohol. The seven items included on the sedation subscale range from 1 (not at all) to extremely (10) with higher measurements indicating higher sedation. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Area Under the Curve was used to calculate the final score reported for the BAES.
As a single summary measure, AUC, was calculated for BAES outcomes based on scores recorded at numerous time points throughout the adlib drinking session The calculation was based on the trapezoidal methods using times 50, 90, 110, 150, 170, 210, and 230 . Based on the distribution, each AUC was log-transformed. Higher AUC levels correspond to greater levels of sedation.
Measured: 50-230 minutes after the priming drink during lab session
Craving AUC: Priming Dose Phase
Craving for alcohol based on Alcohol Urge Questionnaire (AUQ, Bohn et al., 1995), which is an 8 item measurement of self-reported alcohol urges that has been shown to be strongly related to alcohol dependence severity. Each item is scored from 1 (strongly disagree) to 7 (strongly agree), with a higher score indicating higher craving. Craving for alcohol based on Alcohol Urge Questionnaire is calculated using Area Under the Curve (AUC). A single summary measure, AUC was calculated for AUQ outcomes based on scores recorded at numerous time points throughout the priming drink session. The calculation was based on the trapezoidal methods using times -20, 10, 20, 30, 40, 50 minutes before/after priming drink. Based on the distribution, each AUC was log-transformed. Higher AUC levels correspond to greater alcohol urge.
Measured: 0-50 minutes after the priming drink
Sedation Response to Alcohol: Priming Dose Phase
Brief Biphasic Alcohol Effects Scale-Sedation subscale, measuring sedation effects of alcohol with higher measurements indicating higher sedation. Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. The subscale total range is 0-70, these scores are logged transformed.
Measured: 0-50 minutes after priming drink
Stimulation Response to Alcohol: Priming Dose Phase
Brief Biphasic Alcohol Effects Scale-Stimulation subscale, measuring stimulation effects of alcohol with higher measurements indicating higher stimulation. Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. The subscale total range is 0-70, these scores are logged transformed.
Measured: 0-50 minutes after priming drink

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Drinks Consumed at Lab Session (Day 7) (time frame: Day 7). The study lists 7 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 9 Mar 2020.
