A single 25 mg dose of psilocybin, but not 10 mg, reduced depression scores more than a 1 mg control dose over three weeks in adults with treatment-resistant depression. In this phase 2 trial, 233 participants were randomly assigned to 25 mg, 10 mg, or 1 mg of synthetic psilocybin with psychological support. The 25 mg group showed an average 12-point drop on the MADRS depression scale versus a 5.4-point drop in the 1 mg group, a significant difference. The 10 mg group did not differ significantly from control. Response and remission rates at three weeks supported the primary result, but sustained response at 12 weeks was not significantly different.

A single 25-mg dose of synthetic psilocybin combined with psychological support was safe, tolerable, and acceptable for 10 adult women with anorexia nervosa or partial remission. No clinically significant changes occurred in electrocardiogram, vital signs, or suicidality. Two participants developed asymptomatic hypoglycemia that resolved within 24 hours. All adverse events were mild and transient. The findings suggest psilocybin therapy may be a promising treatment for female anorexia nervosa, a condition with no FDA-approved medications and high physiological risks.

Psilocybin treatment shows promise for anorexia nervosa, a psychiatric illness with high mortality and limited treatment options, but studies remain preliminary. This article synthesizes first-hand experiences from 10 individuals with lived experience, offering thematic insights on the potential benefits and constraints of psilocybin treatment for anorexia. The authors contextualize these perspectives within their phase 1 pilot study findings, providing a nuanced exploration of how to optimize such treatments for this vulnerable population.

A single 25-mg dose of synthetic psilocybin, given with psychological support, was safe and tolerable for 10 adult women with anorexia nervosa. No clinically significant changes occurred in heart health, vital signs, or suicidality. Two participants had temporary low blood sugar that resolved within a day. All side effects were mild and short-lived. Participants' reports indicated the treatment was acceptable. These results suggest psilocybin therapy may be a safe approach for female anorexia, a condition with no approved medications and high medical risk.
