(published  May 20211)

Phase II Trial: 24 patients with major depressive disorder, participants who received psilocybin-assisted therapy showed improvement in blinded clinician rated–assessed depression severity and in self-reported secondary outcomes through the one-month follow-up

Conclusion: Psilocybin was efficacious in producing large, rapid, and sustained antidepressant effects in patients with major depressive disorder

Phase IIB Trial: Randomised, controlled 233 patients with treatment resistant depression (TRD) received single dose of psilocybin; showed reduction in symptoms of depression at three weeks through to completion (12 weeks) vs. controls.
