Summary

Dr. Vivian Winkler, a psychiatrist and psychotherapist at the Czech National Institute of Mental Health, presents her clinical and therapeutic experiences from the PSIKET_001 study, a phase 2 randomized, double-blind, placebo-controlled trial comparing psilocybin (25 mg) and ketamine (250 mg) for treatment-resistant depression (TRD). The study design includes two preparatory sessions, a dosing session, and two integration sessions, with a 14-day hospitalization requirement. The primary outcome is the antidepressant effect at 24 hours, with secondary outcomes including duration of effect over two weeks and longer-term follow-up. Recruitment has been challenging, with only 43 participants dosed out of a target of 60, due to skepticism from psychiatrists and stigma. Dr. Winkler shares key lessons: high doses are safe in a controlled setting, but experiences can be emotionally intense; placebo responses are disappointing for participants; the hospital environment is not ideal for integration; and mystical experiences are not as common as expected, possibly due to cultural factors. She emphasizes that psychedelics are not a magic bullet and that integration should be broader, incorporating the experience into the patient’s life journey. She also highlights the limitations of clinical trial settings and the importance of maintaining therapeutic boundaries.
