Design outcomes

Primary

MeasureTime frame
Main Objective: The primary aim of the study is to assess the efficacy and feasibility of psilocybin in the treatment of Anorexia Nervosa. ;Secondary Objective: As a secondary aim, we wish to use Magnetic Resonance Imaging (MRI) and electroencephalography (EEG) to examine the neuronal underpinnings of treatment with psilocybin in this patient group. ;Primary end point(s): Eating Disorder Examination interview and questionnaire Readiness and Motivation Questionnaire ;Timepoint(s) of evaluation of this end point: The EDE will be measured at baseline and at the primary endpoint (6 weeks later). It will then be assessed 6 months after the final study visit. The EDE-Q and RMQ will be assessed at baseline and every 2 weeks until primary endpoint. They will then be assessed monthly for 6 months after the final study visit, and again at 12 months post the final study visit.
