This Phase I trial aims to inform the development of safety protocols for psilocybin-assisted therapy. Psychedelics, including psilocybin, are increasingly being recognized as a successful treatment option for many mental health concerns. In order to decrease the risks associated with its clinical use, more data is required regarding its physiological effect...
BACKGROUND: Posttraumatic stress disorder (PTSD) and depression are highly comorbid. Psilocybin exerts substantial therapeutic effects on depression by promoting neuroplasticity. Fear extinction is a key process in the mechanism of first-line exposure-based therapies for PTSD. We hypothesized that psilocybin would facilitate fear extinction by promoting hipp...
The Yale Program for Psychedelic Science (YPPS) supports a multi-disciplinary research community dedicated to investigating the effects of psychedelic substances on brain function, cognition, and behavior, including their therapeutic potential in treating neuropsychiatric conditions. In support of this mission, YPPS is testing the safety and efficacy of psil...

Psilocybin is being investigated as a potential treatment for psychiatric and neurological disorders. Only a few studies have evaluated the pharmacokinetics (PKs) of psilocybin and have used body weight-adjusted dosing. Data on PKs and the PK-pharmacodynamic (PD) relationship of fixed doses that are commonly used are unavailable. The present study characteri...
There is increasing interest in the therapeutic potential of psilocybin. In rodents, the serotonin precursor, 5-hydroxytryptophan (5-HTP) and psilocybin induce a characteristic 5-HT2A receptor (5-HT2AR)-mediated head twitch response (HTR), which is correlated with the human psychedelic trip. We examined the role of other serotonergic receptors and the trace ...
Several lines of evidence suggest that classic hallucinogens such as psilocybin can facilitate behavior change in addictions such as alcohol dependence. The proposed investigation is a multi-site, double-blind active-controlled trial (n = 180, 90 per group) contrasting the acute and persisting effects of psilocybin to those of diphenhydramine in the context ...
Mental health disorders such as depression and anxiety are major contributors to the overall global health burden. COVID-19 has further aggravated mental health disorders and also increased substance abuse due to lockdowns1. The Global Burden of Disease reported that the pandemic has led to a 27.6% increase in cases of major depressive disorder (MDD) and a 2...
Patients characterized by stress-related disorders such as depression display elevated circulating concentrations of pro-inflammatory cytokines and a hyperactive HPA axis. Psychedelics are demonstrating promising results in treatment of such disorders, however the mechanisms of their therapeutic effects are still unknown. To date the evidence of acute and pe...
ImportanceAlthough classic psychedelic medications have shown promise in the treatment of alcohol use disorder (AUD), the efficacy of psilocybin remains unknown.ObjectiveTo evaluate whether 2 administrations of high-dose psilocybin improve the percentage of heavy drinking days in patients with AUD undergoing psychotherapy relative to outcomes observed with a...
Psychedelics, also known as classical hallucinogens, affect processes related to perception, cognition and sensory processing mostly via the serotonin 5-HT2A receptor (5-HT2AR). This class of psychoactive substances, which includes lysergic acid diethylamide (LSD), psilocybin, mescaline and the substituted amphetamine 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopr...

12097 Background: More than 17 million people in the U.S. live with cancer and up to 25% of them have major depression. Depression leads to lower treatment adherence, reduced quality of life, and higher rates of mortality in cancer. Yet, interventions used to treat depression in patients with cancer have limited success. Prior trials using psilocybin to trea...
Background: Across psychotherapeutic frameworks, the strength of the therapeutic alliance has been found to correlate with treatment outcomes; however, its role has never been formally assessed in a trial of psychedelic-assisted therapy. We aimed to investigate the relationships between therapeutic alliance and rapport, the quality of the acute psychedelic e...
Growing interest has been seen in using lysergic acid diethylamide (LSD) and psilocybin in psychiatric research and therapy. However, no modern studies have evaluated differences in subjective and autonomic effects of LSD and psilocybin or their similarities and dose equivalence. We used a double-blind, randomized, placebo-controlled, crossover design in 28 ...
BackgroundPsilocybin, a psychoactive serotonin receptor partial agonist, has been reported to acutely reduce clinical symptoms of depressive disorders. Psilocybin's effects on cognitive function have not been widely or systematically studied.AimThe aim of this study was to explore the safety of simultaneous administration of psilocybin to healthy participant...
BackgroundPsilocybin may have antidepressant properties, but direct comparisons between psilocybin and established treatments for depression are lacking.MethodsIn a phase 2, double-blind, randomized, controlled trial involving patients with long-standing, moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, a selective sero...
BackgroundGrowing evidence suggests psilocybin, a naturally occurring psychedelic, is a safe and promising pharmacotherapy for treatment of mood and substance use disorders when administered as part of a structured intervention. In most trials to date, psilocybin dose has been administered on a weight-adjusted basis rather than the more convenient procedure ...
The aim of the study is to identify neural signatures, behavioral and phenomenological expressions of self-related processes including: sense of agency, semantic distinction between self and other, selflessness (altruism), social agency, embodied self (interoception), perceptual functioning of dissolved self including hallucinations and crossmodal processing...
Importance: Major depressive disorder (MDD) is a substantial public health burden, but current treatments have limited effectiveness and adherence. Recent evidence suggests that 1 or 2 administrations of psilocybin with psychological support produces antidepressant effects in patients with cancer and in those with treatment-resistant depression. Objective: T...
