Safety for Home Administration of Microdose Psilocybin Use

Psychedelic Experiences Clinical Trial

Official title: Safety for Home Administration of Microdose Psilocybin Use

Status Not yet recruiting

Clinical Trial Summary

The goal of this laboratory study is to establish whether and which microdoses of psilocybin are safe to administer at home to healthy participants. Eligible participants will be given ascending doses of psilocybin trihydrate and a single, interspersed, randomized placebo on separate days in single-blind fashion. The participants will be asked to complete questionnaires and undergo safety assessments.

Clinical Trial Description

This study aims to enroll 20 healthy participants who will complete all study procedures. Participants will undergo a standard screening procedure. Baseline measures will be completed before the first dose. Participants will then be given ascending doses of psilocybin trihydrate (1.2 mg, 2.0 mg, 3.0 mg, and 4.2 mg) and a single, interspersed, randomized placebo on separate days in single-blind fashion at the research site. A 1 mg dose of psilocybin anhydrate is equivalent to a 1.19 mg dose of psilocybin trihydrate (used in this study). For each session, participants will be assessed with criteria for the safety of home dosing. If any dose meets criteria for at-home dosing, and a lower dose did not fail these criteria, that dose will be identified as the safe dose for the given participant. After administration of all doses of psilocybin to all participants, if a safe at-home dose was identified for all participants, that will be considered the highest safe dose for at-home administration to be used for future studies. Visit summary: Initial screening: Medical and psychological screening (Approx. 4 hours though portions of this may be completed remotely). Dosing sessions: There will be 5 single-blind laboratory dosing sessions involving administration of ascending doses of psilocybin and a single, interspersed, randomized placebo dose. Baseline questionnaires will be completed on the day of the first dosing visit, and safety assessments will be administered during and at the end of each session. ;
