The Potential Therapeutic Effects of Psychedelic, N, N-dimethyltryptamine (DMT), on Alcohol Use Disorder (AUD)

Registration Number
NCT06070649
Lead Sponsor
Yale University
Brief Summary

This proposed study is a double-blind, randomized, placebo-controlled, parallel-group, laboratory study to determine the effects of DMT, plus psychotherapy, on Alcohol Use Disorder.

Detailed Description

This study is a placebo-controlled, randomized, double blind, clinical trial to investigate the safety, tolerability and efficacy of the psychedelic dimethyltryptamine (DMT), in addition to a short course of psychotherapy, on Alcohol Use Disorder (AUD). The investigators hypothesize that relative to control (0.2 mg/kg/min + Dimethyltryptamine 0.01mg/kg/min infusion plus psychotherapy), a single psychedelic dose of DMT (plus psychotherapy) in individuals with AUD will 1) be safe and 2) well-tolerated, and 3) reduce alcohol consumption measured in the laboratory the day after, and over the following 8 weeks.

Primary Outcome Measures
NameTimeMethod
Safety and tolerability of DMT in women and men with AUDDay 0 through Day 56

Systematic Assessment for Treatment Emergent Effects (SAFTEE) and MedDRA will be used weekly for 8 weeks to assess safety and tolerability of DMT in women and men with AUD.

The effects of DMT, plus psychotherapy, on alcohol consumptionDay 0 through Day 56

We will assess the desire of participants to drink alcohol in an experimental setting using the Alcohol Drinking Paradigm.

Secondary Outcome Measures
NameTimeMethod
The prosocial effects of DMT, plus psychotherapy, and changes in personality traitsDay 0 through Day 56

Prosocial effects with be assessed using the Mindful Attention Awareness Scale (MAAS).

The relationship between acute psychedelic effects of DMT and alcohol consumptionDay 0 through Day 56

The Ego-Dissolution Inventory (EDI) will be used to assess the relationship between acute psychedelic effects of DMT and alcohol consumption.

The long-term effects of a single dose of DMT, plus psychotherapy, on alcohol consumption over the subsequent 8 weeks.Day 0 through Day 56

Substance use disorder behaviors and risks with the Brief Addiction Monitor (BAM) will be used to assess the long-term effects of a single dose of DMT, plus psychotherapy on alcohol consumption.

The relationship between the intensity of subjective psychedelic experience with lifetime history of chronic stress and traumaDay 0 through Day 56

The Childhood Trauma Questionnaire (CTQ-SF) will be used to assess the relationship between the intensity of subjective psychedelic experience with lifetime history of chronic stress and trauma.
