Official title

Phase 1 Study of the Safety, Tolerability, Electrophysiological Effects and Efficacy of DMT in Humans

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this phase 1 study is to investigate the safety and efficacy of dimethyltryptamine (DMT) in individuals with depression and healthy controls. We hypothesize that administration of DMT will result in decreases in depression, associated symptoms, and neuroplastic changes in depressed subjects. We expect that DMT will induce changes in neuroplasticity as indexed using electroencephalographic (EEG) measures and tasks in both depressed individuals and healthy volunteers, though to different degrees. These neuronal changes may in parallel cause changes in mood measured both in healthy and depressed subjects, which will be captured using appropriate psychometric measures of mood.
