Summary

This trial will study how a single dose of psilocybin affects negative thinking and brain activity in people with depression that doesn't improve with standard treatments. Psilocybin is a classic psychedelic compound that has shown potential in treating mood and substance use disorders.

Who is the study for?
This trial is for adults aged 18-55 with treatment-resistant major depressive disorder (MDD), who have not improved after trying multiple antidepressants. Participants must be right-handed, able to read well, and have stopped all antidepressant medications at least two weeks before the study starts. They should also be under ongoing mental health care.
What is being tested?
The study tests how a single dose of psilocybin affects self-focused thought patterns in people with MDD resistant to standard treatments. It involves brain scans (fMRI) to see changes in brain activity related to these thought processes.
What are the potential side effects?
Psilocybin can cause headaches, nausea, increased heart rate and blood pressure, psychological distress or confusion during the experience ('bad trip'), and potential temporary changes in perception or mood.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for depression include pharmacotherapy and psychotherapy. Pharmacological treatments often involve antidepressants such as SSRIs (Selective Serotonin Reuptake Inhibitors), SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors), and tricyclic antidepressants, which work by increasing the levels of neurotransmitters like serotonin and norepinephrine in the brain. Psilocybin, a serotonin receptor agonist, binds to serotonin receptors, potentially leading to rapid and sustained antidepressant effects. Psychotherapeutic approaches like Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT) focus on altering negative thought patterns and improving interpersonal relationships. Understanding these mechanisms helps patients and clinicians choose the most appropriate treatment, potentially leading to better outcomes and personalized care.
