Brief Summary:
The goal of the proposed project is to begin rigorous study of the clinically relevant effects of non-psychoactive phytocannabinoid cannabidiol (CBD) in patients with severe alcohol use disorder (AUD). This double-blind, randomized proof-of-concept study (n = 40) is designed to assess feasibility and contrast effects of extended (8 weeks) treatment with CBD to those of placebo in AUD patients. Participants with AUD will be randomized to receive either placebo or 600mg CBD/day (PO) for 4 weeks, immediately followed by 1200mg CBD/day (PO) for an additional 4 weeks (8 total weeks). These doses were chosen to reproduce serum CBD levels reported to reduce alcohol-seeking behavior in animal studies. Measures will include circulating levels of CBD, safety measures (THC serum levels, adverse events, cognitive and motoric function), and physiological and psychological domains relevant to AUD (including self-reported craving, depression, and anxiety, and responses to personalized scripts designed to elicit stress- and cue-induced craving and anxiety). Assessments will be conducted following 1 day, 1 week, and 4 weeks of treatment with each dose of CBD vs. placebo, and 1 and 4 weeks after the cessation of treatment. Drinking outcomes across 8 weeks of treatment and 4 weeks of follow-up will also be assessed as an exploratory outcome.

Detailed Description:
There is increasing recognition of the roles of the endocannabinoid system in neurobiological processes and behavioral domains relevant to addiction. The non-psychoactive phytocannabinoid cannabidiol (CBD) has attracted considerable attention due to its lack of abuse potential, its excellent safety profile, its unique and complex pharmacology, and evidence that it affects anxiety and stress response in animal models and humans. There is a growing body of preclinical data demonstrating that CBD produces marked and persisting decreases in alcohol self-administration and preference for alcohol, and alcohol-, cue- and stress-induced reinstatement of alcohol-seeking behavior, yet there are few studies of the effects of CBD in humans with addictive disorders, and none in alcohol dependent patients.

Primary Outcome Measures :
  1. Number of Adverse Events [ Time Frame: Up to Week 12 ]
  2. Mean Addiction Resource Center Inventory-Short Form (ARCI-SF) Score [ Time Frame: Up to Week 9 ]
    49-item assessment of the subjective effects of acute doses of drugs of abuse. The ARCI-SF measures the subjective effects of a variety of drugs such as alcohol, morphine, LSD, and pentobarbital by a score for each subset. The higher a participant scores on a subset, the more similar the effects of the drug are to the known drug such as alcohol.

  3. Rey Auditory Verbal Learning Task (RAVLT) Score [ Time Frame: Week 1 ]
    RAVLT measures verbal learning and declarative memory. During the task, 15 nouns are read aloud for 5 consecutive trials. Each trial is followed by a free recall test in which the participant is asked to recall the words that were just read to them. The raw score is the sum of correctly recalled words across 5 trials. Raw scores are converted to standardized T-scores. T-scores range from 20-100 with a mean of 50; higher scores indicate better performance.

  9. Automated Operation Span Task (OSPAN) Score [ Time Frame: Week 1 ]
    OSPAN measures working memory in the presence of distractions. Specifically, the OSPAN sums correctly recalled and ordered items from a memory set in the presence of distractors. The total score is calculated as a sum based on the number of correct answers within a block for the duration of the task. Higher scores indicate better working memory capacity.

  10. Automated Operation Span Task (OSPAN) Score [ Time Frame: Week 5 ]
    OSPAN measures working memory in the presence of distractions. Specifically, the OSPAN sums correctly recalled and ordered items from a memory set in the presence of distractors.

  11. Reading Span (RSpan) Score [ Time Frame: Week 1 ]
    Participants read sets of short sentences consisting of 3, 4, 5, or 6 words per sentence. Half of the sentences are anomalous, and the other half are not. Participants are asked to read each sentence aloud one word at a time and then indicate whether the sentence made semantic sense or not. At the end of each set, participants are asked to remember the last word of each sentence, in order, to the best of their ability. Set sizes increase as the task progresses. Everyone starts with a set size of three words per sentence and ends at a set size of six words per sentence; there are three sentences for each set size. The final score is based on the total number of words recalled. Scores range from 0 to 54, with higher scores indicating better performance.

The final score is based on the total number of words recalled. Scores range from 0 to 54, with higher scores indicating better performance.

  13. Symmetry Span (SymSpan) Score [ Time Frame: Week 1 ]
    SymSpan consists of 12 trials during which participants assess the symmetry of a series of matrices. After choosing "yes" or "no" for symmetry, a 4 × 4 grid containing a red box appears (the participant's task is to remember the position of the red box). After several combinations, participants view a blank grid and must recall the box positions in correct order from the previous grid screens. Trial length ranges from two to five symmetry-memory matrices per trial. Total scores consist of total number of correct box positions recalled.

  14. Symmetry Span (SymSpan) Score [ Time Frame: Week 5 ]
    SymSpan consists of 12 trials during which participants assess the symmetry of a series of matrices. After choosing "yes" or "no" for symmetry, a 4 × 4 grid containing a red box appears (the participant's task is to remember the position of the red box). After several combinations, participants view a blank grid and must recall the box positions in correct order from the previous grid screens. Trial length ranges from two to five symmetry-memory matrices per trial. Total scores consist of total number of correct box positions recalled.

  15. Rotation Span (RotSpan) Score [ Time Frame: Week 1 ]
    Working memory assessment. Begins with distractor task asking the participant to judge whether a rotated letter is presented correctly, or is a mirrored image of the letter. Next, to-be-remembered items are presented as arrows of either short or long length and pointing in one of eight different directions. The rotation-arrow sequence is repeated from two to five times per trial. Scores are calculated by summing the number of arrows correctly recalled in the correct order.

Secondary Outcome Measures :
  1. Change in Penn Alcohol Craving Scale (PACS) Score [ Time Frame: Baseline, Week 9 ]
    5-item questionnaire that measures an individual's craving to drink alcohol in the past week. Items are ranked on a Likert scale from 0-6. Scores range from 0-30; higher scores indicate greater craving to drink alcohol.

  2. Change in Beck Anxiety Inventory (BAI) Score [ Time Frame: Baseline, Week 9 ]
    21-item self-report measure of anxiety. Items are ranked on a Likert scale ranging from 0 (Not at all) to 3 (Severely). The total score is the sum of responses and ranges from 0 to 63, where higher scores indicate greater levels of anxiety. Scores are interpreted as follows: 0 - 21 = low anxiety; 22 - 35 = moderate anxiety; 36 and above = potentially concerning levels of anxiety.

  3. Change in Beck Depression Inventory-II (BDI-II) Score [ Time Frame: Baseline, Week 9 ]
    21-item self-report inventory designed to measure the severity of depression symptomatology. Participants rank each item on a Likert scale from 0-3. The total score is the sum of responses and ranges from 0-63; higher scores indicate greater severity of depression

  4. Change in Alcohol Abstinence Self-Efficacy Scale (AASE): Temptation Subscale [ Time Frame: Baseline, Week 9 ]
    20-item assessment of one's self-confidence in their ability to avoid drinking, with items specifically related to temptation to drink. Responses are rated on a Likert scale from 0-4. The total score is the sum of response and ranges from 0-80; lower overall scores indicate lower temptation to drink.

  5. Change in Alcohol Abstinence Self-Efficacy Scale (AASE): Confidence Subscale [ Time Frame: Baseline, Week 9 ]
    20-item assessment of one's self-confidence in their ability to avoid drinking, with items specifically related to confidence to avoid drinking. Responses are rated on a Likert scale from 0-4. The total score is the sum of response and ranges from 0-80; higher overall scores indicate higher confidence in avoiding drinking.
