Clinical Trial Summary

This study will collect data that measures the effects of a psychedelic intervention on patients struggling with alcohol use disorder (AUD). The study design will be a double blind, randomized, active-comparator trial with two study arms. Subjects randomized to Arm 1 (n=40) will receive individual psychotherapy sessions plus a 30 mg dose of oral psilocybin. Arm 2 subjects (n=40) will receive individual psychotherapy sessions and a 0.75 mg/kg dose of intramuscular ketamine.

Inclusion criteria:

• Male
• Weight between 50kg and 150kg
• No known allergies to rescue medication
• Meets criteria for DSM-V moderate to severe AUD.
• Have at least 4 heavy drinking days (5 or more standard drinks in a day) in the past 30 days.

• No serious traumatic brain injury (TBI) in the past 2 years
• No substance use disorder over the past 12 months
• Family member/friend for pick-up, overnight post-drug session monitoring.
• No MRI contraindications Exclusion Criteria: Drug/medication assessment that yields: nonprescription medication use, nutritional supplement, or herbal supplement (except when approved by the study investigators), medically unstable, current medication use that has significant potential to interact with study drug (e.g., antidepressants, antipsychotics, psychostimulants, treatments for addictions, other dopaminergic or serotonergic agents, lithium, anticonvulsants, or benzodiazepines). Psychiatric assessment that yields:1) history of severe suicide attempt, 2) current suicidality 3) first degree relative with schizophrenia or schizoaffective disorder, 4) comorbid substance use including cocaine, psychostimulant, or opioid use disorder within past 12 months and/or any use within past 30 days, 5) history of co-occurring psychotic episode/diagnosis including schizophrenia, schizoaffective disorder, schizophreniform, substance-induced psychosis, delusional disorder, or psychosis not otherwise specified, 6) high risk of adverse emotional or behavioral reaction based on the medical monitor's clinical evaluation that may also yield evidence of serious current stressors, a lack of meaningful social support, antisocial behavior, and/or serious personality disorders amongst other conditions.
