Psilocybin-Assisted Therapy for Intergenerational Trauma

This is an open-label psilocybin-assisted therapy study that will examine the safety and tolerability of psilocybin-assisted therapy in the offspring of genocide survivors with mood and anxiety disorders.

The study will also investigate the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes to the psychological effects of parental exposure to genocide, and changes to psychological resilience.

This study is investigating whether Psilocybin-assisted therapy improves depression, anxiety and stress symptoms in the offspring (biological children) of genocide survivors. Intergenerational trauma is the concept that the effects of experiencing extreme stress can be perpetuated to future generations. A genocide here is defined by the extinction or threat of extinction of a racial, religious or ethnic group, by an oppressive regime. A genocide survivor here is defined by an individual who survived or escaped a genocide in their country of origin. Currently, there are no evidence-based treatments developed specifically for the syndrome associated with Intergenerational trauma. This study aims to assess the safety and tolerability of psilocybin-assisted therapy, and assess the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes to the psychological effects of parental exposure to genocide, and changes to psychological resilience.

Participants will be asked to attend one or more screening visits to assess eligibility. If eligible, participants will be treated with two separate doses of the study medication, Psilocybin, 3-4 weeks apart. This is an open-label research study, meaning all participants will receive Psilocybin (25mg). Two trained clinical practitioners will work with participants across preparation, dosing, and integration processes. Participants will complete assessments throughout the study until their participation has ended. Safety measures are in place to check the overall health and well-being of participants

Participation will consist of:

* Screening Period (up to 4 weeks): Phone screen, informed consent, eligibility assessment.
* Tapering \& Enrollment Period (variable): Enrollment, supervised medical tapering where necessary as discussed with the study doctor, biomarker collection and psychometric baseline assessments.
* Preparatory \& Treatment Period (up to 14 weeks): Three preparatory sessions with study clinicians, assessments; two dosing days at least three weeks apart, three weekly integration sessions with study clinicians following each dose, a 72-hour check-in call after each dosing day, assessments.
* Follow-Up Period (up to 5 weeks): Follow-up one month after final integration session, assessments, clinical evaluation, biomarker collection
