Brief Summary:
The purpose of this study is to determine whether psilocybin, a hallucinogenic drug, is effective in reducing depressive symptoms and amount of drinking in patients with co-occurring Major Depressive Disorder (MDD) and Alcohol Use Disorder (AUD).

Condition or disease Intervention/treatment Phase
Major Depressive Disorder Alcohol Use Disorder Drug: Psilocybin Drug: Placebo Phase 2

Detailed Description:
The objectives of this double-blind, placebo-controlled study are to test the hypotheses that a single high (25 mg) oral dose of psilocybin will lead to enduring reductions in depressive symptoms (as measured by the clinician-rated grid version of the Hamilton Depression Rating Scale, or GRID-HAMD) and amount of drinking (as measured using the Time Line Follow Back, or TLFB, procedure) compared to placebo in patients with co-occurring MDD and AUD. 90 male and female volunteers who are between the ages of 21 and 65 years old and who meet Diagnostic and Statistical Manual, Fifth Edition (DSM-5) criteria for MDD and AUD will be recruited from the community and complete all study procedures. Volunteers will be randomized to one of two study arms (psilocybin [N=45] or placebo [N=45]), and will complete a drug administration session paired with a brief Motivational Interviewing intervention for alcohol use. Volunteers will undergo assessments of depression and alcohol use before and after treatment. After primary endpoints are measured, all volunteers will receive a second, unblinded intervention with a single high dose of psilocybin (25 mg) to test a secondary hypothesis that two doses of psilocybin are more effective in treating MDD with co-occurring AUD than a single dose.

Primary Outcome Measures :
  1. Change from baseline in grid-version of the Hamilton Depression Rating Scale (GRID-HAMD) score [ Time Frame: Baseline and 1 month after first experimental drug administration session ]
    The GRID-Hamilton Depression Rating Scale is a 17-item clinician-administered rating scale designed to assess severity of depressive symptoms. The score range for the GRID-HAMD is 0 to 52, with higher score indicating more severe depression.

  2. Change from baseline in percentage of days abstinent as measured by the Time Line Follow Back (TLFB) assessment [ Time Frame: Baseline and 3 months after first experimental drug administration session ]
    The TLFB is a widely used, standardized, calendar-based retrospective self-report assessment to quantify daily alcohol use. The investigators will examine the primary outcome of percentage of abstinent days in the past 90 days.

  3. Change from baseline in percentage of days of heavy drinking as measured by the TLFB assessment [ Time Frame: Baseline and 3 months after first experimental drug administration session ]
    The TLFB is a widely used, standardized, calendar-based retrospective self-report assessment to quantify daily alcohol use. The investigators will examine the primary outcome of percentage of drinking days in the past 90 days.

  4. Change from baseline in gamma-glutamyl transferase (GGT) [ Time Frame: Baseline and 3 months after first experimental drug administration session ]
    Change in GGT (IU/L) will be measured by peripheral blood tests. GGT is elevated in chronic drinkers. Elevated GGT due to drinking can begin to reduce after a week of abstinence, and can return to normal levels after roughly 4 weeks of abstinence.

  5. Change from baseline in the percentage of carbohydrate deficient transferrin relative to total transferrin concentration (%CDT) [ Time Frame: Baseline and 3 months after first experimental drug administration session ]
    Change in %CDT will be measured by peripheral blood tests. %CDT can become elevated after 1 to 2 weeks of heavy drinking, and can return to normal levels within 2 weeks of abstinence.

  6. Change from baseline in the ratio of aspartate transaminase to alanine transaminase (AST/ALT) [ Time Frame: Baseline and 3 months after first experimental drug administration session ]
    Change in AST/ALT ratio will be measured by peripheral blood tests. Elevated AST/ALT ratio has been associated with heavy drinking, and can return to normal levels after extended abstinence.


Secondary Outcome Measures :
  1. Change from baseline in Quick Inventory of Depressive Symptomatology - Self Rated (QIDS-SR) score [ Time Frame: Baseline, 1 week, 1 month, and 3 month post-drug-session visits; 6 and 12 month follow-ups after the second experimental drug administration session. ]
    The Quick Inventory of Depressive Symptomatology is a 16-item self-report questionnaire that measures the nine symptom domains of a depressive episode, with higher scores indicating greater depression severity. This questionnaire is rated on a scale of 0 to 3. These values represent varying answers for each item and can be found within the questionnaire.

  2. Change from baseline in State Trait Anxiety Index (STAI) score [ Time Frame: Baseline, 1 week, 1 month, and 3 month post-drug-session visits; 6 and 12 month follow-ups after the second experimental drug administration session ]
    The STAI is a 40-item self-report measure that assessing anxiety on two different scales: State and Trait. State anxiety is scored on a 4-point scale (1 = Not at all; 2 = Somewhat; 3 = Moderately so; 4 = Very much so) and Trait anxiety is scored on the 4-point scale (1 = Almost never; 2 = Sometimes; 3 = Often; 4 = Almost always).

  3. Change from baseline in percentage of days abstinent as measured by the TLFB assessment [ Time Frame: Baseline, 1 month post drug administration session, 3 months after the second (unblinded) drug administration session, and at 6 and 12 months post second (unblinded) drug administration session ]
    The TLFB is a widely used, standardized, calendar-based retrospective self-report assessment to quantify daily alcohol use. The investigators will examine the secondary outcome of percentage of abstinent days either within the last 30 days or the last 90 days, depending on study visit.

  4. Change from baseline in percentage of days of heavy drinking as measured by the TLFB assessment [ Time Frame: Baseline, 1 month post drug administration session, 3 months after the second (unblinded) drug administration session, and at 6 and 12 months post second (unblinded) drug administration session ]
    The TLFB is a widely used, standardized, calendar-based retrospective self-report assessment to quantify daily alcohol use. The investigators will examine the secondary outcome of percentage of drinking days either within the last 30 days or the last 90 days, depending on study visit.

  5. Change from baseline in GGT [ Time Frame: Baseline, 1 month post drug administration session, 3 months after the second (unblinded) drug administration session ]
    Change in GGT (IU/L) will be measured by peripheral blood tests. GGT is elevated in chronic drinkers. Elevated GGT due to drinking can begin to reduce after a week of abstinence, and can return to normal levels after roughly 4 weeks of abstinence.

  6. Change from baseline in %CDT [ Time Frame: Baseline, 1 month post drug administration session, 3 months after the second (unblinded) drug administration session ]
    Change in %CDT will be measured by peripheral blood tests. %CDT can become elevated after 1 to 2 weeks of heavy drinking, and can return to normal levels within 2 weeks of abstinence.

  7. Change from baseline in AST/ALT ratio [ Time Frame: Baseline, 1 month post drug administration session, 3 months after the second (unblinded) drug administration session ]
    Change in AST/ALT ratio will be measured by peripheral blood tests. Elevated AST/ALT ratio has been associated with heavy drinking, and can return to normal levels after extended abstinence.
