In Basel, only a few hundred meters from where LSD was first synthesized, we tested LSD-assisted therapy for major depression in a randomized trial comparing two high doses with two low doses, each paired with supportive psychotherapy. This Backstory reflects on treating patients, long dosing days, and what remains uncertain.

This trial aimed to assess the efficacy of lysergic acid diethylamide (LSD)-assisted therapy in patients with moderate-to-severe major depressive disorder. This was a randomized, parallel, double-blind, low-dose controlled trial (Clinicaltrials.gov: NCT03866252). Patients were randomly assigned in a 1:1 ratio to receive supportive psychotherapy and either 100 μg + 200 μg LSD or 25 μg + 25 μg...

Psilocybin-assisted psychotherapy (PAP) has been associated with antidepressant effects. Trials to date have typically excluded participants with complex presentations. Our aim was to determine the feasibility of PAP in a complex population, including high levels of treatment resistance in major depressive and bipolar disorder and patients with baseline suicidality and significant comorbidity....

A recent clinical trial by Rosenblat at al.1 demonstrates feasibility of a flexible dosing schedule of psilocybin in individuals with severely treatment-resistant depression (TRD), including those with co-morbid conditions or bipolar II disorder (BPII),...

Existing treatments for adults with anorexia nervosa (AN) have limited effectiveness. AN is a brain-based disorder with behavioral and cognitive features leading to severe undernourishment. Peck et al. conducted a small open trial suggesting safety and tolerability of psilocybin for AN,1 opening an avenue for further investigation into the neural mechanisms involved.

Results from a recent Phase II trial of psilocybin-assisted therapy for treatment-resistant depression1 suggest modest efficacy but raise concerns about potential for serious adverse effects. The study highlights the need for rigorous assessment of blinding integrity, expectancy, and further study of factors that may contribute to risk in vulnerable populations.
