Investigating the Effects of a Psychedelic-augmented Mental Imagery-based Intervention for Young People With Self-harm Behaviour: an Experimental Medicine Study
Approximately 20% of young people experience self-harm behaviour in their lives. Self-harm can occur across different mental health disorders, and lead to negative outcomes and risk of suicide. Current treatments are long, costly and do not suit all young people, making it essential to research alternative treatments. Therapy combined with psychedelic drugs ...

This is an open-label pilot trial to assess the safety and feasibility of a novel 8-week psilocybin-assisted psychotherapy intervention to facilitate successful tapering/discontinuation of opioid pain medication in adult patients receiving long-term opioid therapy for chronic pain. Participation will last approximately 8 months and includes one or two psiloc...
A Phase 2b, Randomized, Double-blind, Placebo-controlled, Multi-center Study of the Effects of Psilocybin-assisted Psychotherapy on Psychiatric and Existential Distress in Advanced Cancer
The purpose of this research is to study the safety and effects of single-dose psilocybin 25mg versus an active placebo (single dose niacin 100mg) in the treatment of anxiety, depression, and existential distress (i.e., loss of meaning and hope; fear of death) in advanced cancer (i.e., stage 3 or 4). Study medications will be administered in conjunction with...
Psilocybin vs Ketamine for Alcohol Use Disorder
This study will collect data that measures the effects of a psychedelic intervention on patients struggling with alcohol use disorder (AUD). The study design will be a double blind, randomized, active-comparator trial with two study arms. Subjects randomized to Arm 1 (n=40) will receive individual psychotherapy sessions plus a 30 mg dose of psilocybin. Arm 2...
Digital Intervention for Psychedelic Preparation (DIPP): A Randomised Controlled Feasibility Trial Comparing Meditation and Music-Based Programs in Healthy Volunteers.
This randomised controlled feasibility trial evaluates the Digital Intervention for Psychedelic Preparation (DIPP), a novel 21-day self-guided program designed to prepare individuals for psychedelic experiences. Forty healthy volunteers will be randomly assigned to either a meditation-based intervention or a music-based control condition. Both groups will fo...
Assessing the Safety, Tolerability, and Efficacy of Psilocybin Therapy Followed by Accelerated Intermittent Theta Burst (aiTBS) Repetitive Transcranial Magnetic Stimulation (rTMS) for Treatment-Resistant Major Depressive Disorder
The purpose of this study is to determine the safety and feasibility of sequencing psilocybin therapy with a short-duration, aiTBS protocol (Stanford Accelerated Intelligent Neuromodulation Therapy, or SAINT) in individuals with treatment-resistant major depressive disorder. This will be a phase II 2x2 design (device and dose) clinical trial. 100 participant...
Pragmatic Trial of Psilocybin Therapy in Palliative Care (PT2PC): A Multicenter Triple-blind Phase 2 Randomized Controlled Trial of Psilocybin Therapy for Demoralized Adults Near the End of Life
This multicenter, triple-blind, phase 2, randomized controlled trial will evaluate the efficacy and safety of psilocybin therapy compared to an active control in treating demoralization in adults near the end of life (≤2 years life expectancy). After providing written informed consent, participants deemed eligible for this trial will be randomized to a brief...
Does Serotonin System Stimulation Increase Pro-social Behavior? - A Comparative Pharmacological Neuroscientific Study in Healthy Humans
The study looks into whether administering psychedelic substances that stimulate the serotonin system influences pro-social behavior when compared to administering substances that stimulate the dopamine system in healthy individuals. Psychedelic substances have been shown to be powerful modulators of social perception and behavior during the acute experience...
A Double-blind, Phase II Feasibility Study to Assess the Safety and Efficacy of Psilocybin Microdosing Combined With Psychotherapy in Treatment-resistant Depression
Objective: To assess the safety and efficacy of a six-week microdosing regimen of psilocybin combined with short-term, experience-based psychotherapy in patients with treatment-resistant depression who have not responded to previous pharmacological or long-term psychological interventions. Hypothesis: Compared to baseline, the group that begins with psilocyb...
Open Label, Phase 2 Study for Evaluating the Feasibility, Safety and Efficacy of Psychotherapy Assisted Psilocybin for Treatment of Severe Obsessive Compulsive Disorder (OCD) in Drug and/or Psychotherapy Resistant Patients.
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by recurrent distressing thoughts and substantial anxiety, accompanied by repetitive behaviors or mental rituals. Individuals with OCD often have diminished quality of life, and functional impairment. The disorder cause high personal, societal and economic costs. Current availab...
