Outcome Measures

Primary Outcomes (11)

  • Parkinson's Disease (PD) symptom severity

    Measured by Unified Parkinson's Disease Rating Scale (MDS-UPDRS)

    Baseline to 30 days following last drug dose

  • Suicide Risk

    Measured by Columbia Suicide Severity Rating Scale (C-SSRS)

    Baseline to 30 days following last drug dose

  • Psychotic symptoms

    Measured by Enhanced Scale for the Assessment of Positive Symptoms for Parkinson's Disease (eSAPS-PD)

    Baseline to 30 days following last drug dose

  • Psychotic symptoms

    Measured by Psychosis and Hallucinations Questionnaire in Parkinson's Disease (PsycH-Q)

    Baseline to 30 days following last drug dose

  • Cognitive Safety

    Measured by Cambridge Neuropsychological Test Automated Battery (CANTAB)

    Baseline to 30 days following last drug dose

  • Caregiver/support person-reported distress

    Measured by Neuropsychiatric Inventory Caregiver Distress Questionnaire (NPI-Q)

    Baseline to 90 days following last drug dose

  • Participant-reported subjective experience

    Measured by 5-Dimensional Altered States of Consciousness Rating Scale (5D-ASC)

    Measured on each drug administration session day, following drug dose

  • Safety and tolerability of psilocybin therapy for depression and anxiety in people with PD

    Incidence, severity, and frequency of Adverse Events (AEs) including Treatment-Emergent AEs (TEAEs) and Serious AEs (SAEs)

    Baseline to 3 months following last drug dose

  • Recruitment rate

    Measured by the number of participants entering the trial multiplied by the number of months of active recruitment time

    Baseline to 3 months following last drug dose

  • Retention rate

    The number of participants completing all stages of the study will be presented as a percentage of the number of total number of participants recruited

    Baseline to 3 months following last drug dose

  • Treatment Satisfaction of psilocybin therapy for depression and anxiety in people with PD

    Measured by the treatment satisfaction questionnaire * 5-item scale, plus three free response questions * items are ranked from 1-to-7, with higher scores representing better treatment satisfaction

    Baseline to 3 months following last drug dose

Other Outcomes (7)

  • Effects of psilocybin therapy on depression in people with PD (exploratory)

    Baseline to 3 months following last drug dose

  • Effects of psilocybin therapy on anxiety in people with PD (exploratory)

    Baseline to 3 months following last drug dose

  • Cognitive Flexibility

    Baseline to 30 days following last drug dose

  • +4 more other outcomes
