Cannabis is the most commonly used psychoactive substance in Canada (Lowry \& Corsi, 2020). A sub-group of cannabis users develop a condition known as Cannabis Use Disorder (CUD), which is defined as a regular pattern of cannabis use that causes performance difficulty at work, school and relationships (Hasin et al., 2013). A review of current treatments available for CUD indicate the lack of a pharmacological and psychological treatment with high success rates, which highlights the importance of exploring potential psychosocial interventions for the treatment of CUD. Given the evidence of psilocybin's therapeutic potential in the treatment of substance use disorders (de Veen et al., 2017), we aim to conduct a study using psilocybin-assisted-psychotherapy in the treatment of CUD. The study aims to evaluate the feasibility, safety, tolerability and potential therapeutic effect of 2 doses \[25 mg\] of psilocybin administered as part of an 8-week Motivational Enhancement Therapy (MET) and supportive therapy. This trial will be the first to evaluate the potential treatment effects of psilocybin on symptoms of CUD.

This phase II trial studies whether psilocybin with psychotherapy is safe and if it works for improving chronic pain in cancer patients who require opioids to manage their pain. Psilocybin is taken from the mushroom Psilocybe mexicana. Psilocybin acts on the brain to cause hallucinations (sights, sounds, smells, tastes, or touches that a person believes to be real but are not real). This may impact a patient's "total pain", a view that accounts for the psychological, spiritual, and social factors that contribute to their experience of pain. Psychotherapy uses methods such as discussion, listening, and counseling to help patients change the way they react to environmental triggers that may cause a negative reaction. Giving psilocybin with psychotherapy may be safe and helpful for improving chronic pain in cancer patients who require opioids to manage their pain.

The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.

The goal of this clinical trial is to investigate the effects of psilocybin on synaptic vesicular density (SVD) as measured by the positron emission tomography (PET) radiotracer, 18F-SynVesT-1, in participants with amnestic Mild Cognitive Impairment (aMCI) and healthy participants. The investigators hypothesize that SVD levels in the brain will be higher following the ingestion of psilocybin in comparison to placebo, and that increases in SVD will be associated with improvements in cognition. 60 participants (30 with aMCI, and 30 sex and age matched healthy volunteers) will: * Be randomized to receive either: 1. Two 25 mg macrodoses of psilocybin separated by 1 week. 2. Two placebo doses separated by 1 week. * Receive a baseline 18F-SynVesT-1 PET scan, clinical, and neuropsychological assessments. * Receive a 18F-SynVesT-1 PET scan one week after the last dose of treatment. * Receive a third PET scan at any time within 4 weeks of the screening visit to quantify tauopathy with the \[18F\]T807 radiotracer. * Receive clinical and neuropsychological testing 1, 4, and 12 weeks after the last treatment. Researchers will compare placebo vs. experimental groups to see if psilocybin will increase SVD, and if increases in SVD are associated with cognitive improvements.

This is a Phase 2, single-center study to explore the efficacy, safety, and tolerability of up to two 25-mg doses of psilocybin administered at an interval of 9 to 10 weeks in patients with MDD and cancer. This two-part study will administer a fixed dose (25 mg) of psilocybin in a double-blind, randomized, placebo-controlled portion (Dosing Session 1) and subsequently allow rollover into an open-label portion (Dosing Session 2; fixed dose of psilocybin, 25 mg) for patients who do not achieve remission of MDD symptoms after the first dose. In Dosing Session 1, groups of two to four patients will be randomized, as a cohort, to receive either psilocybin 25 mg or niacin 100 mg (active placebo) in a group session, with each patient supported by their dedicated study therapist and monitored by a second therapist via video feed. In Dosing Session 2, all eligible participants (i.e., patients who have not achieved remission defined as MADRS \< 10 at V7) will receive psilocybin 25 mg in an open-label fashion using the group session model. The study population will include adult men and women who are 18 years of age or older and have diagnoses of both MDD and a malignant neoplasm. MDD is defined as the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) diagnostic criteria for a single or recurrent episode of MDD without psychotic features. A diagnosis of a malignant neoplasm is defined as having a diagnostic code from C00 to C97 according to the International Classification of Diseases, 10th edition (ICD-10). Participants will be recruited through referrals from specialized psychiatric and oncology services as well as through patient self-referrals. The majority of participants will have no prior exposure to psilocybin or so-called "magic mushrooms"; however, participants with prior recreational experience with psilocybin or "magic mushrooms" are eligible.

This study is a 12-week (in addition to up to 30 days of screening) randomized, double-blind, placebo-controlled, parallel-group trial. The primary objective of this study is to assess the effectiveness, safety, and tolerability of single-dose psilocybin (25 mg)-assisted therapy in comparison to active placebo (1 mg micro-dose) psilocybin-assisted therapy in patients with bipolar II depression who have not responded to adequate trials with at least two first or second-line treatments for bipolar II depression (i.e. quetiapine, lithium, lamotrigine, sertraline, or venlafaxine as monotherapy or adjunctive therapy, or bupropion adjunctive therapy). The active placebo is a substance that looks identical to the study medication but contains less therapeutic ingredients, and thus is less capable of producing the transformative and meaningful aspects of psychedelic experience compared to the 25 mg dose. Participants will have a total of 11 study visits over a period of up to 16 weeks, which includes 5 therapy sessions from trained study therapists.

This is a feasibility study to examine the use of use of Psilocybin (magic mushrooms) to alleviate pain in chronic neuropathic pain. While theoretical mechanisms demonstrate promise, there is no clinical evidence. This vacuum of clinical evidence has been occupied by a "psychedelic hype bubble" with media communications touting psychedelics as a 'miracle cures'. The mismatch between evidence and perception creates an urgent need for RCT to fill this significant gap. This trial aims to address this gap by conducting a pilot trial assessing the feasibility, tolerability, and preliminary efficacy of psilocybin for chronic neuropathic pain to inform a future larger, multi-centre study. The purpose is to conduct a randomized control double-blinded trial of psilocybin and active placebo (dextromethorphan). At this time, the aim of the trial is to recruit 30 participants from St. Michael's Hospital, to learn whether it will be feasible to plan a larger study in the future.

Limit: 5000 characters. Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of certain medications such as risperidone. The purpose of this study is to use an established SV2A radiotracer produced at our Centre to determine the feasibility of integrating PET imaging in to psilocybin trials. The preliminary imaging data will assess whether psilocybin's antidepressant effects are related to changes in synaptic density in adults with TRD, and whether any changes in synaptic density are associated with psilocybin's actions on the 5-HT2AR.

We propose a first-of-its-kind open-label clinical trial to investigate the feasibility, tolerability, and safety of administering psilocybin in autistic adults with treatment-resistant depression (TRD). In this study, 20 participants (intellectually able and fluent-speech adults) with autism and co-occurring TRD will receive around 20 hours of manualized psychotherapy that has previously been used with psilocybin (Agin-Liebes et al., 2020). They will also receive psilocybin at 2 different time points, firstly a safety dose of 10mg, followed by a treatment dose of 25mg. This study design is in accordance with previous studies investigating the use of psilocybin with psilocybin-assisted therapy (PAT) to treat TRD (Carhart-Harris et al., 2016, 2018)

This study is an open-label, single-arm, proof-of-concept study, wherein treatment resistant bipolar depression (TRBD) participants will receive one 25 mg dose of oral psilocybin accompanied by preparatory, monitoring, and integration psychotherapy sessions (psilocybin-assisted psychotherapy, or PAP). Using fMRI (functional magnetic resonance imaging), the findings of this study will provide data on the neurobiological mechanism of psilocybin in TRBD. The primary objective is to understand the dynamic role of amygdala activity by evaluating the neurobiological effects of a single psychedelic dose (25 mg) of oral psilocybin in individuals with a moderate to severe major depressive episode and a primary diagnosis of Bipolar II Disorder, with 2 or more failed treatment trials (i.e., treatment resistant bipolar depression \[TRBD\]). Neurobiological effects will be determined by evaluating the association between post-treatment right amygdala activity during the facial affect task (determined by fMRI one day after the psilocybin dose) and antidepressant effects (determined by changes in the Montgomery-Åsberg Depression Rating Scale \[MADRS\] scores over time, during the one-week period post-psilocybin dose). This is a single-arm, open-label clinical trial wherein all participants will receive the same study intervention. Hypothesis: Increased right amygdala activity on fMRI with emotional stimuli one day after psilocybin treatment will be associated with greater antidepressant effects in the one-week period post-treatment in individuals with TRBD.

Psilocybin for OCD

Toronto, Ontario
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, feasibility, and clinical effects of psilocybin administration in those with OCD. Ten participants with treatment-resistant OCD will receive two doses of 25mg of psilocybin under supportive conditions, two weeks apart. The investigators hypothesize that two sessions of psilocybin 25mg administered under supportive conditions to participants with treatment-resistant OCD will lead to significant reductions in OCD symptoms.

Frequently Asked Questions

How much do clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a medical study ?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest clinical trials ?
Most recently, we added Psilocybin for Stress Response, Psilocybin-Assisted Therapy for Post-Traumatic Stress Disorder and Psilocybin-Assisted Psychotherapy for Irritable Bowel Syndrome to the Power online platform.
