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).
Study Design
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:
|
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:
|
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.

Outcome Measures
Primary Outcome Measures
- 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
- 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
