Apomorphine and psilocybin to improve recovery from coma in the intensive care unit: protocol for a prospective, open-label, dose-escalation study.

BMJ Open September 22, 2026 Anna Kristina Eigenbrodt, Poul P Laigaard, Melika Hassani et al.

Recovery of consciousness after brain injury remains a major challenge in the intensive care unit (ICU), and pharmacological treatments that directly promote awakening from coma and other disorders of consciousness (DoC) are lacking. We hypothesise that simultaneously targeting the two core components of consciousness by pharmacological means-arousal with apomorphine and awareness with...

EFFICACY AND SAFETY OF PSILOCYBIN IN TREATMENT-RESISTANT DEPRESSION: A REVIEW

International Journal of Innovative Technologies in Social Science September 21, 2026 Mateusz Gawin, Emilia Koziara, Mateusz Gadzina et al.

Major depressive disorder (MDD) is one of the leading causes of disability worldwide. A substantial proportion of patients fail to achieve remission through standard monoaminergic therapies, meeting the clinical criteria for treatment-resistant depression (TRD). TRD is associated with significant clinical morbidity and a profound economic burden on healthcare systems. This review evaluates the...

Pharmacokinetics and safety of a modified‐release psilocybin formulation: A SAD Phase I trial in normal‐weight and overweight/obese participants

British Journal of Clinical Pharmacology September 21, 2026 Anna Signor, Stefano Comai, Gianfranco Pasut et al.

AIMS: This study aimed to evaluate the safety, tolerability and pharmacokinetics of a novel oral modified-release psilocybin formulation (REL-P11) in normal-weight and overweight/obese healthy adults and to assess its suitability for controlled, subperceptual exposure, in light of emerging evidence supporting serotonergic modulation in metabolic disorders. METHODS: Simulation-based modelling...

A Randomized, Double-Blind, Placebo-Controlled Single-Ascending-Dose Study to Identify a Subperceptual Dose of Psilocybin in Healthy Adults

Pharmaceuticals September 21, 2026 Naama Levy‐Cooperman, Edward M. Sellers, Paul Glue et al.

Background/Objectives: Psilocybin shows therapeutic promise for several psychiatric disorders, but the acute perceptual and cognitive alterations produced by conventional doses (10–25 mg) require in-clinic supervision, which limits scalability. Whether the therapeutically relevant pharmacology of psilocybin can be safely separated from its hallucinogenic activity remains unresolved. To address...

Exploring the Therapeutic Potential of Psilocybin: A Comprehensive Review of Clinical Trial Evidence and Implications for Rescheduling

Mini-Reviews in Medicinal Chemistry September 18, 2026 Fatemeh Abolhasani, Hojjat Rezaiezadeh, Mohammad Amin Langarizadeh et al.

Psilocybin, a compound found in certain species of Psilocybe mushrooms, shows potential as a treatment for various psychiatric conditions. In the past decade, a growing body of evidence has shown the effectiveness of psilocybin in treating conditions, such as treatment-resistant depression, generalized anxiety disorder, post-traumatic stress disorder, and substance use disorders. This review...

Perceptions and Attitudes on Psilocybin-Assisted Therapy among Underrepresented People with Cancer.

Journal of Pain and Symptom Management September 18, 2026 Megan Miller, Molly Meyers, Candace Oglesby-Adepoju et al.

Psilocybin-assisted therapy (PAT) shows promise for alleviating psychological and existential distress among people with cancer; however, research is limited by homogeneous samples, raising concerns about generalizability and equity. To explore perceptions and attitudes of PAT among a subset of people with cancer who have been underrepresented in research. A qualitative descriptive study was...

Psilocybin restores social novelty investigation in male SAPAP3 knockout mice and engages prefrontal–hippocampal circuitry

Molecular Psychiatry September 17, 2026 James J Gattuso, Bilgenur Bezcioglu, Jenna Hendey et al.

Obsessive-compulsive disorder (OCD) remains difficult to treat, and evidence indicates that social dysfunction, common across obsessive-compulsive and related disorders, is an under-recognized clinical burden. SAPAP3 knockout (KO) mice, a well-established model of compulsive behavior, exhibit social abnormalities, suggesting broader disruptions in circuits relevant to social cognition. Here, we...

Exploratory safety, tolerability, and feasibility of psilocybin-assisted psychotherapy for adults with co-occurring treatment-resistant depression and cluster B personality disorders

npj Mental Health Research September 16, 2026 Orly Lipsitz, Ryan M Brudner, Zoe Doyle et al.

Cluster B personality disorders (PDs) are highly comorbid with depression and are associated with attenuated antidepressant response. No clinical trials to date have reported on psilocybin-assisted psychotherapy (PAP) in comorbid treatment-resistant depression (TRD) and PDs. This is the first clinical trial to describe a subgroup of ten participants with a comorbid PD ( n = 9 cluster B; n = 1...

Psilocybin and ayahuasca in treatment-resistant depression: clinical evidence, methodological constraints and ethical challenges: a narrative review

Frontiers in Psychiatry September 15, 2026 Serena Chiara Civardi, Filippo Besana, Federico Durbano et al.

Background Treatment-resistant depression (TRD) is a major clinical challenge, with many patients failing to respond to conventional antidepressants. Psychedelic compounds such as psilocybin and ayahuasca have recently gained attention as potential rapid-acting therapies. Beyond their neurobiological effects, methodological, ethical, and real-world applicability concerns are critical for...

5-HT2A receptor activation is dispensable for psilocybin-induced fear extinction and neuroplasticity in mice.

Chinese medical journal September 15, 2026 Yingjie Du, Xiangting Zhao, Quan Chen et al.

Psilocybin facilitates fear extinction in rodents, but its clinical utility is hampered by 5-hydroxytryptamine (5-HT) 2A-receptor-mediated hallucinogenic effects. This study aimed to explore whether 5-HT2A receptor is obligatory for psilocybin's fear extinction and neuroplasticity effect. Male C57BL/6J mice underwent auditory-cue fear conditioning. Ketanserin (5-HT2A/2C antagonist) or MDL100907...
