Trial Summary
What is the purpose of this trial?This trial is testing COMP360, a new treatment for adults who have not responded to other depression treatments. Participants will receive one of three doses of COMP360 along with psychological support. The goal is to see if this combination can help improve their depression symptoms.
Do I have to stop taking my current medications for the trial?Yes, you must agree to discontinue all prohibited medications at Screening.
What safety data is available for psilocybin in treating depression?Psilocybin has been studied for its safety and pharmacological effects. It is a serotonergic psychedelic found in 'magic mushrooms' and has shown promise in treating depression. Studies have shown that psilocybin does not aggravate certain pathological conditions and may protect against cell injury in controlled doses. An open-label study on healthy adults with escalating doses of psilocybin reported its pharmacokinetics and safety profile, indicating its potential safe use under controlled conditions. However, caution is advised with higher concentrations, especially in individuals with cardiovascular conditions.12567
Is the drug psilocybin a promising treatment for depression that doesn't respond to other treatments?Yes, psilocybin shows promise as a treatment for depression that doesn't respond to other treatments. Studies have shown it can reduce depression symptoms, and it has been tested safely in clinical trials. It works quickly and has been effective even when other medications haven't helped.34101213
What data supports the idea that Psilocybin is an effective drug for Treatment-Resistant Depression?The available research shows that psilocybin can lead to significant and lasting improvements in people with treatment-resistant depression. In several studies, patients experienced rapid and substantial relief from depression symptoms after just one or two doses. These effects were observed to last for a long time, even in those who had not responded to other treatments. While more research is needed to fully understand its benefits and how best to use it, the initial results are promising.1891113

The pharmacology of psilocybin. [2016]Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is the major psychoactive alkaloid of some species of mushrooms distributed worldwide. These mushrooms represent a growing problem regarding hallucinogenic drug abuse. Despite its experimental medical use in the 1960s, only very few pharmacological data about psilocybin were known until recently. Because of its still growing capacity for abuse and the widely dispersed data this review presents all the available pharmacological data about psilocybin.
[Hallucinogenic mushrooms]. [2018]The group of hallucinogenic mushrooms (species of the genera Conocybe, Gymnopilus, Panaeolus, Pluteus, Psilocybe, and Stropharia) is psilocybin-containing mushrooms. These "magic", psychoactive fungi have the serotonergic hallucinogen psilocybin. Toxicity of these mushrooms is substantial because of the popularity of hallucinogens. Psilocybin and its active metabolite psilocin are similar to lysergic acid diethylamide. These hallucinogens affect the central nervous system rapidly (within 0.5-1 hour after ingestion), producing ataxia, hyperkinesis, and hallucinations. In this review article there are discussed about history of use of hallucinogenic mushrooms and epidemiology; pharmacology, pharmacodynamics, somatic effects and pharmacokinetics of psilocybin, the clinical effects of psilocybin and psilocin, signs and symptoms of ingestion of hallucinogenic mushrooms, treatment and prognosis.
Psilocybin with psychological support for treatment-resistant depression: an open-label feasibility study. [2022]Psilocybin is a serotonin receptor agonist that occurs naturally in some mushroom species. Recent studies have assessed the therapeutic potential of psilocybin for various conditions, including end-of-life anxiety, obsessive-compulsive disorder, and smoking and alcohol dependence, with promising preliminary results. Here, we aimed to investigate the feasibility, safety, and efficacy of psilocybin in patients with unipolar treatment-resistant depression.
Return of the psychedelics: Psilocybin for treatment resistant depression. [2017]Psilocybin, the clinically most researched classic psychedelic has recently been tested for its safety and efficacy in a clinical population of treatment resistant depression. The efficacy of psilocybin in clinical depression previously demonstrated in the elecrophysiologic and neuroimaging findings as also in neuropsychological assessments is further validated by the findings of this rigorously conducted randomized trial. Mechanism of action of psilocybin and efficacy in treatment resistant depression are discussed in this paper. Ethical issues of conducting clinical trials with psychedelics are also discussed with particular emphasis on their relative safety and absence of addiction potential. Implications of these issues for conduct of larger trials for establishing risk benefit ratio in treatment resistant depression are further suggested.
Pharmacokinetics of Escalating Doses of Oral Psilocybin in Healthy Adults. [2022]Psilocybin is a psychedelic tryptamine that has shown promise in recent clinical trials for the treatment of depression and substance use disorders. This open-label study of the pharmacokinetics of psilocybin was performed to describe the pharmacokinetics and safety profile of psilocybin in sequential, escalating oral doses of 0.3, 0.45, and 0.6 mg/kg in 12 healthy adults.
Transcriptional regulation in the rat prefrontal cortex and hippocampus after a single administration of psilocybin. [2022]Psilocybin is a serotonergic psychedelic found in "magic mushrooms" with a putative therapeutic potential for treatment-resistant depression, anxiety, obsessive-compulsive disorder, and addiction. In rodents, psilocybin acutely induces plasticity-related immediate early genes in cortical tissue; however, studies into the effects on subcortical regions, of different doses, and the subsequent translation of corresponding proteins are lacking.
Effects and safety of Psilocybe cubensis and Panaeolus cyanescens magic mushroom extracts on endothelin-1-induced hypertrophy and cell injury in cardiomyocytes. [2021]Prevalence of major depression in people with chronic heart failure is higher than in normal populations. Depression in heart failure has become a major issue. Psilocybin-containing mushrooms commonly known as magic mushrooms, have been used since ancient times for their mind healing properties. Their safety in cardiovascular disease conditions is not fully known and may pose as a risk for users suffering from these illnesses. Study investigates the effects and safety of Psilocybe cubensis and Panaeolus cyanescens magic mushrooms use from genus Psilocybe and Panaeolus respectively, in a pathological hypertrophy conditions in which endothelin-1 disorder is a contributor to pathogenesis. We examined the effects of the mushrooms extracts on endothelin-1-induced hypertrophy and tumor necrosis factor-α (TNF- α)-induced cell injury in H9C2 cardiomyocytes. Mushrooms were oven dried and extracted with cold and boiling-hot water. H9C2 cardiomyocytes were induced with endothelin-1 prior to treatment with extracts over 48 h. Cell injury was stimulated with TNF-α. Results proposed that the water extracts of Panaeolus cyanescens and Psilocybe cubensis did not aggravate the pathological hypertrophy induced by endothelin-1 and also protected against the TNF-α-induced injury and cell death in concentrations used. Results support medicinal safe use of mushrooms under controlled conditions and cautioned use of higher concentrations.
[Treatment with psilocybin: applications for patients with psychiatric disorders]. [2021]After a cessation of almost 40 years, there is renewed interest into therapeutic applicationsof the serotonergic psychedelic psilocybin for the treatment of patients with various psychiatric disorders. PubMed was searched for clinical trials into "psilocybin" between 2000 and 2020, complemented by handsearching. Articles were also screened for explanatory models and working mechanisms. Psilocybin has been studied in 9 clinical trials: for the treatment of substance use disorders, depression, end-of-life anxiety, demoralization, and obsessive-compulsive disorder. Results show that psilocybin is well tolerated, with only limited side-effects, while even patients with treatment-resistant disorders sometimes show marked, long-term improvements after one or a few sessions. Initial results are encouraging, but there are several limitations. More research is needed to determine which patient populations can benefit, what role setting and the placebo response play, and how these novel treatments can be optimized.
Efficacy and safety of psilocybin-assisted treatment for major depressive disorder: Prospective 12-month follow-up. [2022]Preliminary data suggest that psilocybin-assisted treatment produces substantial and rapid antidepressant effects in patients with major depressive disorder (MDD), but little is known about long-term outcomes.
Single-dose psilocybin-assisted therapy in major depressive disorder: A placebo-controlled, double-blind, randomised clinical trial. [2023]Psilocybin has been suggested as a novel, rapid-acting treatment for depression. Two consecutive doses have been shown to markedly decrease symptom severity in an open-label setting or when compared to a waiting list group. To date, to our knowledge, no other trial compared a single, moderate dose of psilocybin to a placebo condition.
Psilocybin-assisted therapy for major depressive disorder: An exploratory placebo-controlled, fixed-order trial. [2023]Several early phase studies have demonstrated that psilocybin-assisted therapy has rapid-acting and persisting antidepressant effects from just one or two doses. However, methodological limitations (e.g., placebo-control, blinding) limit interpretability of the existing literature.
Psilocybin for treatment resistant depression in patients taking a concomitant SSRI medication. [2023]Psilocybin is being investigated as a treatment in adults with treatment-resistant depression (TRD). Withdrawal from serotonergic antidepressant drugs is a common prerequisite for taking part in trials of psilocybin due to the possibility of ongoing antidepressant drugs altering the psychedelic effect. This phase II, exploratory, international, fixed-dose, open-label study explored the safety, tolerability, and efficacy of a synthetic form of psilocybin (investigational drug COMP360) adjunct to a selective serotonin reuptake inhibitor in participants with TRD. Participants received a single 25 mg dose of psilocybin alongside psychological support and were followed-up for 3 weeks. The primary efficacy end point was change in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score from Baseline at Week 3. Secondary end points were safety, including treatment-emergent adverse events (TEAEs), the proportion of responders and remitters at Week 3, and the change from Baseline to Week 3 in Clinical Global Impression-Severity (CGI-S) score. Nineteen participants were dosed and the mean Baseline MADRS total score was 31.7 (SD = 5.77). Twelve (63.2%) participants had a TEAE, most of which were mild and resolved on the day of onset. There were no serious TEAEs or indication of increased suicidal ideation or behavior. At Week 3, mean change from Baseline in MADRS total score was -14.9 (95% CI, -20.7 to -9.2), and -1.3 (SD = 1.29) in the CGI-S. Both response and remission were evident in 8 (42.1%) participants. Larger, comparator-controlled trials are necessary to understand if this paradigm can optimize treatment-outcome where antidepressant drug withdrawal would be problematic.
Assessing potential of psilocybin for depressive disorders. [2023]There has been increasing interest in the role psilocybin may play in the treatment of depressive disorders. Several clinical trials have shown psilocybin to have efficacy in reducing symptoms of depression.
