Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the effects of a supratherapeutic dose of psilocybin on cardiac repolarization.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This study will be a double-blind, single-dose, randomized, placebo-controlled, 4-treatment, 4-period, 12-sequence crossover design in 36 healthy volunteers (adult male and/or female subjects). Subjects will be randomly assigned to 1 of 12 different treatment administration sequences, whereby each sequence will include 3 double-blind treatments (therapeutic dose of psilocybin, supratherapeutic dose of psilocybin, and placebo) and 1 open-label positive control treatment (moxifloxacin).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Treatment A (IP at therapeutic dose)

A single therapeutic dose of psilocybin.

Drug: Psilocybin
The psilocybin used in this study is synthetically manufactured in a laboratory and meets quality specifications suitable for human research use. The active drug is encapsulated using a hydroxypropyl methylcellulose (HPMC) capsule and contains psilocybin (API only in a capsule).
Other Names:
  • Psilocybine
  • Psilocibin
  • Indocybin
  • Experimental: Treatment B (IP at supratherapeutic dose)

    A single supratherapeutic dose of psilocybin.

    Drug: Psilocybin
    The psilocybin used in this study is synthetically manufactured in a laboratory and meets quality specifications suitable for human research use. The active drug is encapsulated using a hydroxypropyl methylcellulose (HPMC) capsule and contains psilocybin (API only in a capsule).
    Other Names:
  • Psilocybine
  • Psilocibin
  • Indocybin
  • Placebo Comparator: Treatment C (Placebo - Negative control)

    A single dose of placebo-to-match psilocybin MCC capsules.

    Drug: Micro-Crystalline Cellulose
    The placebo used in this study is encapsulated using a HPMC capsule and contains micro-crystalline cellulose.

    Active Comparator: Treatment D (Placebo - Positive control)

    A single 400 mg dose of moxifloxacin.

    Drug: Moxifloxacin
    The positive comparator used in this study is a 400 mg moxifloxacin tablet.
    Other Names:
  • Avelox
  • Moxeza
  • Outcome Measures

    Primary Outcome Measures

    1. Change from baseline (Day -1) QTcF (ΔΔQTcF) following up to 24 hours post administration of a supratherapeutic dose of psilocybin. [up to 24 hours post-dose]

      Replicate electrocardiograms (ECGs) (10 ECG replicates) for the determination of ΔQTc interval will be extracted from the continuous digital 12-lead ECG recording at the -0.75, -0.50, and -0.25 hours prior to dosing and then at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 hours post-dose.

    Secondary Outcome Measures

    1. Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v4.0 [Up to 30 Days Post Dose]

      # of participants with TEAE following administration of psilocybin and moxifloxacin
