The long-term objective of this project is to characterize how psilocybin affects visual perception and the brain's representation of the visual environment. It is known that psilocybin alters aspects of visual perception, but the underlying brain mechanisms contributing to these effects are poorly understood. The proposed work will address these questions i...
Primary Aim: In participants with OUD, to characterize adverse events associated with adding two psilocybin doses to a stable buprenorphine-naloxone formulation. Secondary Aim: To evaluate the effect of psilocybin treatment on the effectiveness of a buprenorphine-naloxone maintenance therapy. Secondary Aim: To evaluate the effect of concurrent buprenorphine-...
This phase I trial tests the safety and side effects of a second episode of psilocybin-assisted group therapy and how well it works in treating anxiety and distress in patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and had a partial response to their first retreat. Up to 50% of patient...
This study seeks to provide insight on psilocybin's effects on mechanisms of chronic pain among patients with co-morbid chronic low back pain and depression (CLBP+D). Participants will receive either a single high-dose of psilocybin (25mg absolute dose) or methylphenidate (40mg absolute dose). Participants will be asked to complete assessments of pain, depre...
The primary aim is to determine the feasibility of enrolling and 15 women with chronic pelvic pain (CPP) that have failed one conventional for CPP to obtain preliminary safety data on a single administration of a moderate dose of pharmaceutical grade psilocybin (25 mg) in combination with psychotherapy sessions (two pre-dose preparatory and three post-dose i...
The primary purpose of this study is to preliminarily determine if the use of psilocybin to promote abstinence from methamphetamine is feasible and well tolerated in populations such as those found in Northern Louisiana. Investigators will assess the impact of psilocybin-facilitated treatment on methamphetamine abstinence, craving, negative affect, cognitive...
Psilocybin, a serotonin receptor agonist in the brain, significantly and quickly improves depressive symptoms while inducing profound acute subjective effects. The benefit-risk ratio of psilocybin in treatment-resistant depression seems favorable, but needs to be confirmed. Moreover, the role of 5-HT2A receptors, involved in the psychedelic experience, on th...
This retrospective observational study examines the effects of psychedelic-assisted psychotherapy (PAP) with lysergic acid diethylamide (LSD) or psilocybin in patients with treatment-resistant depressive, anxiety, or addictive disorders. Data will be analyzed from patients treated at the University Hospitals of Geneva between June 2020 and April 2025 who obt...
The purpose of this study is to assess the safety and effectiveness of co-administered MDMA and psilocybin in military Veterans with a diagnosis of Posttraumatic Stress Disorder (PTSD). To apply or learn more, please view our website: https://hopkinspsychedelic.org/pamvet The proposed randomized, double-blind, active control study will compare a single exper...
The goal of this clinical trial is to test psilocybin in combination with mindfulness training in healthy adults. The main question it aims to answer is "Does mindfulness training enhance the effects of psychedelic therapy (psilocybin) on mental health?" Interested individuals will complete an initial eligibility session and eligible participants will then b...
The purpose for this study is to observe the real world experience of participants who are receiving psilocybin in the context of (alcoholism) Alcohol Use Disorder without intervening in the model of care. The study team will engage directly with the participants to examine the outcomes in participants who have been deemed eligible and appropriate to receive...
The goal of this clinical trial is to understand how personally meaningful, autobiographically salient music compares to standardized playlists when combined with psilocybin in healthy adults ages 21 to 75. The main questions it aims to answer are: Does autobiographically salient music lead to stronger emotional responses to music, greater acute subjective e...
Rationale: Recent evidence shows that Lysergic Acid Diethylamide (LSD), even when administered in low, non-hallucinogenic doses, can produce analgesic effects and improve pain tolerance in a sample of healthy volunteers. Such results complement what was already observed with other serotonergic psychedelics such as psilocybin: survey studies and case series i...
About one in three people with major depression respond poorly to standard antidepressant treatments. This kind of depression is called treatment-resistant depression, and it can lead to long-term disability, financial challenges, and a higher risk of suicide. Psilocybin-a compound found in certain mushrooms-has shown early promise as a new treatment for thi...
This is an open-label psilocybin-assisted therapy study that will examine the safety and tolerability of psilocybin-assisted therapy in the offspring of genocide survivors with mood and anxiety disorders. The study will also investigate the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes...
This randomized controlled clinical trial evaluates the effectiveness of psilocybin and psilocybin-assisted cognitive behavioral therapy (CBT) in the management of Major Depressive Disorder (MDD). The study aims to compare the effects of psilocybin-only therapy, CBT, and psilocybin-assisted CBT on depression symptoms, neurochemical markers, inflammatory mark...
This study is a phase 2 single-site, double-blind, placebo-controlled, randomized clinical trial with an open-label extension phase to examine the safety of psilocybin (25 mg) combined with psychological support (Psi-PS) for treatment of approximately 40 military veterans and first responders (ages 21-65) with co-occurring alcohol use disorder (AUD) and post...
Psychogenic non-epileptic seizures (PNES) are functional paroxysmal motor disorders that may be clinically suggestive of epilepsy but are not associated with the electroencephysiological and electroencephalographic changes of epilepsy. Thus, hyper-connectivity of the regions of the default mode network (DMN) linked to executive control could be involved in t...
The study hypothesis is that the antidepressant effect of psilocybin is mediated by a normalization of the functioning of the positive valence system. Depressive states, especially moderate to severe depressions that associate a certain level of anhedonia, produce an overvaluation of the cost of efforts and an infra-evaluation of the possible rewards derived...
This study will examine the effects of psilocybin on Lyme disease symptom burden and quality of life in people with Post-Treatment Lyme Disease (PTLD). This pilot study will evaluate the therapeutic potential of psilocybin in people with well-documented current Post-Treatment Lyme Disease (PTLD). Study measures will assess the impact of psilocybin-assisted t...
