我是 LongbridgeAI，我可以总结文章信息。一项发表在《临床精神病学杂志》的研究表明，使用迷幻蘑菇素辅助的治疗可能显著减少治疗抵抗性抑郁症患者的慢性自杀意念。该试验在谢帕德·普拉特医院进行，涉及 20 名成年人，他们接受了一次 25 毫克的迷幻蘑菇素剂量。结果显示，到第 12 周，自杀念头减少了 70%，且没有报告严重不良事件。研究人员强调需要进行更大规模的试验以确认这些发现
BALTIMORE, May 26, 2026 /PRNewswire/ -- The Journal of Clinical Psychiatry recently published results from a clinical trial conducted at Sheppard Pratt, examining the efficacy and safety of psilocybin-assisted therapy for individuals experiencing chronic suicidal ideation and treatment-resistant depression. The study, led by Scott T. Aaronson, MD, chief science officer at Sheppard Pratt with Andrew van der Vaart, MD, PhD, psychiatrist at Sheppard Pratt, as first author, provides early evidence that a single dose of psilocybin administered with psychological support may produce rapid and sustained reductions in suicidal thoughts.
The open-label trial enrolled 20 adults diagnosed with major depressive disorder and chronic suicidal ideation who had failed at least two prior antidepressant treatments. Participants received a single 25-mg dose of COMP360 psilocybin within a structured therapeutic protocol that included preparation, supervised administration, and integration sessions. Researchers followed participants for 12 weeks to evaluate changes in suicidal ideation and depressive symptoms.
Findings showed statistically significant reductions in suicidal ideation as early as one week following treatment, with improvements sustained throughout the 12-week follow-up period. By week 12, 70% of participants reported minimal or no suicidal ideation. Participants also experienced significant reductions in depressive symptoms across all post-treatment assessments. No serious adverse events were reported during the trial.
"Chronic suicidality remains one of the most difficult symptoms to treat in psychiatry, particularly for patients who have not responded to conventional therapies," said Dr. Aaronson. "This study represents an important step toward understanding whether psychedelic-assisted therapies may offer another avenue of hope for individuals facing severe and persistent mental health challenges."
The study is among the first prospective clinical trials to specifically evaluate psilocybin-assisted therapy in a population experiencing chronic suicidal ideation. Researchers noted that while the findings are promising, larger randomized controlled trials will be needed to further evaluate efficacy, durability, and long-term safety.
"Individuals living with chronic suicidal ideation are frequently excluded from psychedelic clinical trials, despite having a significant unmet need for new treatment options," said Dr. van der Vaart. "These findings suggest psilocybin-assisted therapy may have the potential to provide rapid and durable relief for some patients when delivered in a carefully structured clinical setting."
The trial was conducted under U.S. Food and Drug Administration Investigational New Drug authorization and approved by the Sheppard Pratt Institutional Review Board. The study appears in the June 2026 issue of the Journal of Clinical Psychiatry.
