A Randomized, Double-Blind, Placebo-Controlled Mechanistic Study to Assess a Single Oral Dose of CYB003 in Participants With Major Depressive Disorder (MDD) and Moderate to Severe Anxiety
Ohio State University
Summary
The goal of this study is to learn how psychedelics may help symptoms of depression and anxiety. Participants with major depressive disorder experiencing symptoms of depression and anxiety will receive one dose of either a drug related to psilocybin or a placebo. Assessments include interviews, self-report questionnaires, EEG and fMRI to measure symptoms and brain function.
Description
Many patients with MDD do not respond or have an incomplete response to treatment with currently available antidepressants. The use of psychedelics (e.g. psilocybin) is being investigated as a new approach to improve depressive symptomatology, however their mechanism of action is still not well understood. Psilocin is the active metabolite of psilocybin responsible for the psychedelic effects of the parent compound. CYB003 is a synthetic, deuterated isotopomer of psilocin, being developed by Cybin for the treatment of MDD. The study will investigate the changes in brain activity, connectivity,…
