Study of the Safety and Feasibility of Psilocybin in Adults With Methamphetamine Use Disorder

July 13, 2023 updated by: University of Wisconsin, Madison

Safety and Feasibility of Psilocybin in Methamphetamine Use Disorder in a Community-Based Sample

The purpose of this research study is to investigate the safety and feasibility of two (2) oral doses of psilocybin when combined with behavioral support for methamphetamine use disorder (MUD). Participants have a diagnosis of methamphetamine use disorder (MUD). Participants can expect to be actively engaged in the study for up to 26 weeks.

Study Overview

Detailed Description

The objective of this study is to determine the safety of psilocybin in adult participants with MUD.

Eligible participants will be adults with methamphetamine use disorder recruited from the community. After physical and psychological screening, and at least 6 hours of psychological support for the psilocybin dosing, each participant will ingest 1 oral dose of psilocybin. All dosing sessions will be attended by 2 specially trained facilitators, in a dedicated Session Room at the University of Wisconsin School of Pharmacy. After eight hours of observation in the dosing room, the participant will stay overnight in the hospital Clinical Research Unit, and complete an integration session with at least one of the session facilitators before discharge to home. Approximately 4 weeks after the first dose, the participant will receive a second oral dose of psilocybin, with the same length of observation.

Participants who decide not to proceed to the second dose will complete two additional integration sessions and study measures through the two-month follow-up.

Up to 26 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of participants who complete at least one dose of psilocybin
Time Frame: Up to 26 weeks

Up to 26 weeks
Changes in substance use
Time Frame: Up to 26 weeks
