What this study is

The purpose of the study is to assess the safety and acceptability of up to two sequential administrations of 25 mg psilocybin with additional therapeutic support in decreasing suicidality in patients with Bipolar Disorder (BD II) depression.

What's being tested

  • Psilocybin

    Intervention · DRUG

    Two sequential administrations of 25 mg psilocybin, 4 weeks apart.

  • Therapeutic Support

    Intervention · BEHAVIORAL

    Five preparatory in-person psychotherapy sessions will be offered before the first administration session during weeks 1, 2, 3, 4, and 5. The optional second administration session will be preceded by a shorter 60 min preparatory session the day before. Each administration session will be followed by 3 integration sessions and will adopt a Mindfulness-based CBT approach (M-CBT), in which a therapist will help the participant to process their experience and how to translate this into actual changes in everyday life. If participants prefer more psychological support after the second administration session, they will be offered additional, optional therapy sessions for the duration of the trial regardless if they opted for a second administration session or not.
