Official title
A Phase 2 Randomized Study Examining the Safety, Feasibility, and Effectiveness of Masking Psilocybin Therapy With General Anesthesia in Major Depressive Disorder
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Major depressive disorder (MDD) affects millions of Americans and remains difficult to treat. Psilocybin, a psychedelic compound, has shown promise for reducing depression symptoms, but a key challenge in psychedelic research is that participants can usually tell whether they received the active drug - making it hard to conduct fully blinded studies. This study (Studying Psilocybin with Anesthesia Controlled by EEG \[SPACE\]) tests a new approach: administering psilocybin while participants are under general anesthesia, so that the noticeable psychological effects of psilocybin are masked. This allows both participants and outcome assessors to remain unaware of whether psilocybin or placebo was given, improving the scientific rigor of the research. Participants with MDD will be randomly assigned to receive either psilocybin or placebo across four dosing sessions conducted under general anesthesia. The study will assess whether this approach is safe and feasible, and will collect early data on whether it may reduce depression symptoms.
