Healthy Clinical Trial - Pairing Psilocybin With Transcutaneous Auricular

Status Not yet recruiting

Clinical Trial Summary

This study will examine whether combining a single dose of psilocybin with non-invasive transcutaneous auricular vagus nerve stimulation (taVNS), a known inducer of neuroplasticity and enhanced memory formation, will enhance the long-term beneficial behavioral effects of psilocybin when compared to sham taVNS by allowing memory for insights gained during the psychedelic experience to remain vivid after they will have faded in subjects who receive psilocybin followed by sham taVNS.

Clinical Trial Description

One hundred and eight adults will receive a single open-label 25 mg dose of psilocybin administered within a "set and setting" (SaS) framework of psychological support provided by trained facilitators, such as has been successfully employed in prior psychedelic studies at University of Wisconsin-Madison. The SaS protocol will include 2-4 hours of preparation, a 6- to 8-hour psilocybin dosing session and an hour-long integration session 1 day and 9 days post dosing. All subjects will receive various combinations of active taVNS or sham taVNS prior to, or following, psilocybin dosing. Active and sham taVNS sessions will last 20 minutes and will occur twice daily (morning and afternoon/evening) for 7 consecutive days, using an "at home" protocol that has been used safely and effectively by study collaborators. taVNS is a non-invasive low-risk procedure. Subjects will be randomized with equal allocation to one of four conditions: 1) seven days of sham taVNS prior to psilocybin dosing and 7 days of active taVNS post- psilocybin dosing (Group 1: n=27); 2) seven days of sham taVNS prior to psilocybin dosing and 7 days of sham taVNS post- psilocybin dosing (Group 2: n=27); 3) seven days of sham taVNS prior to psilocybin dosing and treatment as usual post- psilocybin dosing (Group 3: n=27); and 4) seven days of active taVNS prior to psilocybin dosing and 7 days of sham taVNS post- psilocybin dosing (Group 4: n=27). It is anticipated that a total sample of 108 subjects will be enrolled to provide 100 subjects who complete study activities/assessments sufficient to provide evaluable data for testing study primary and exploratory outcomes. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
