Trial Outcomes & Findings for Effect of Allopregnanolone on Stress-induced Craving (NCT NCT04015869)

NCT ID: NCT04015869

Last Updated: 2025-08-22

Results Overview

The Alcohol Urge Questionnaire (AUQ) is an 8-question, self-administered measure of drinking urges. Questions are in the form of a 7-point scale with participants endorsing the extent to which they agree or disagree with statements relating to desire to drink (4 items), expectation of a desired outcome from drinking (2 items), and inability to avoid drinking if alcohol was available (2 items). Total scores range from 8 (strongly disagree) to 56 (strongly agree).

Measure
Allopregnanolone
On the test day the participant received an allopregnanolone (ALLO) infusion over 175 minutes. On the test day two scripts will be read one trauma related script (most traumatic experience) and one neutral script (relaxed scene given by participant). An alcohol infusion (40mg%) begins at approximately 120 minutes into the ALLO infusion. Once target alcohol dose is reached the alcohol infusion will be clamped and continue for approximately 20 mins.
Placebo
On the test day the participant received a placebo (for allopregnanolone infusion over 175 minutes. On the test day two scripts will be read one trauma related script (most traumatic experience) and one neutral script (relaxed scene given by participant). An alcohol infusion (40mg%) begins at approximately 120 minutes into the ALLO infusion. Once target alcohol dose is reached the alcohol infusion will be clamped and continue for approximately 20 mins.

Measure
Allopregnanolone 100nM
n=5 Participants
Targeted dose of 100 nM of ALLO, a continuous infusion of ALLO for approximately 175 min. Sixty minutes after the start of the infusion, when ALLO levels are relatively stable, the stress induction paradigm will be introduced. Stress and neutral cues will consist of personalized 5-minute scripts created prior to testing. Measures of stress-induced craving and stress-induced anxiety will be presented before the cue (pre), immediately following the cue (post) and 10 minutes after (recovery). An alcohol infusion (40mg%) begins at approximately 120 minutes into ALLO Infusion. Once the alcohol infusion has reached the targeted dose of 40mg% the infusion is clamped for approximately 20 minutes. After 20-minute clamp both infusions will end.

The State Trait Anxiety Inventory (STAI-6) is a 6-item self-rated instrument used to assess anxiety state. The STAI-6 questions included: 1. "I feel calm"; 2. "I am tense"; 3. "I feel upset"; 4. "I am relaxed"; 5. "I feel content"; 6. "I am worried". Each of these questions were rated as: a) "not at all"; b) "somewhat"; c) "moderately"; d) "very much". For questions 2, 3, and 6, the scoring was a = 1, b = 2, c = 3, and d = 4. For the other 3 questions, the scoring was a = 4, b = 3, c = 2, and d = 1. This outcome is for 3. "I feel upset" (scored individually): the scoring for "I feel upset is: a = 1, b = 2, c = 3, and d = 4 (1 not at all upset to 4 very much upset)

Timeframe: Pre-Script 40 minutes before trauma/neutral script is presented

Population: All available data was utilized in the analysis using mixed models

The State Trait Anxiety Inventory (STAI-6) is a 6-item self-rated instrument used to assess anxiety state. The STAI-6 questions included: 1. "I feel calm"; 2. "I am tense"; 3. "I feel upset"; 4. "I am relaxed"; 5. "I feel content"; 6. "I am worried". Each of these questions were rated as: a) "not at all"; b) "somewhat"; c) "moderately"; d) "very much". For questions 2, 3, and 6, the scoring was a = 1, b = 2, c = 3, and d = 4. For the other 3 questions, the scoring was a = 4, b = 3, c = 2, and d = 1. This outcome is for 6. "I am worried" (scored individually): the scoring for "I feel content is: a = 1, b = 2, c = 3, and d = 4 (1 not at all worried to 4 very much worried)
