This open-label, interventional trial (n=19) explored the effectiveness of 25mg of psilocybin as adjunctive therapy to SSRI use in participants with treatment-resistant depression (TRD).

A previous study demonstrated a significant decrease in depressive symptoms after treatment with psilocybin and psychological support, with over 40% of participants maintaining their response at 3 months.

Psilocybin for treatment resistant depression in patients taking a concomitant SSRI medication
This open-label Phase II trial (n=19) investigates the safety, tolerability, and efficacy of synthetic psilocybin (COMP360) as an adjunct to selective serotonin reuptake inhibitors (SSRIs) in adults with treatment-resistant depression (TRD). The study found no serious treatment-emergent adverse events or increased suicidal ideation. It reported a significant decrease in depression (MADRS) and Clinical Global Impression–Severity (CGI-S) scores at week 3, with response and remission observed in 42.1% of participants.
