Healthy Clinical Trial
Official title:
Consciousness and Psilocybin Effects on Well-Being (The CoPE Study): Pilot Phase
This pilot study aims to 1) establish a dosing regimen for intravenous (IV) psilocybin that will allow the drug to be administered to asleep participants without awakening them; and 2) assess whether this dosing regimen produces a psychedelic experience.
The study intervention will be psilocybin administered by the intravenous (IV) route to sleeping and awake participants. The study will test up to two different IV administration protocols in sleeping participants. The first protocol to be tested will consist of 2 mg of psilocybin administered via IV infusion over a 2-minute period. Should this method allow participants to remain asleep for at least 1 hour post-dosing, no further dosing strategies will be evaluated. If the 2-minute IV infusion delivery method disrupts sleep, a second dosing strategy will be examined consisting of 2 mg of IV psilocybin administered over 10 minutes. Whichever dosing strategy causes the least sleep disruption will be selected for administration to awake participants. As part of the study design, some participants may also receive normal IV saline instead of IV psilocybin during the dosing session. For any given participant, the protocol for delivering the normal saline will be identical to the psilocybin protocol they receive (e.g., either IV saline (10 mL) over 2 minutes or IV saline (10 mL) over 10 minute IV infusion). Participants will include medically and psychiatrically healthy biological males and females of any identified gender and racial/ethnic group aged 18 to 45 years. ;
