Main objective
Scope: Efficacy
Primary Objective: The primary objective is to assess the effects of low psilocybin doses on pain perception in FM patients and their association with BDNF levels.
Secondary objectives 1
- Secondary Objective(s): The secondary objective is to assess the impact of low psilocybin doses on mood, cognition, personality, autobiographical memory functioning and psychedelic experience. We will also test whether hypnotic suggestions can moderate the potential effects of psilocybin on pain perception and tolerance. Finally, we will test whether the plasma levels of inflammatory biomarkers (IL-1α, IL-1β, IL-6, IL-8, and TNF)

- Written Informed Consent
- Understanding the procedures and the risks associated with the study
- No regular use of psychotropic medication such as opiates, muscle relaxants, anticonvulsants, sleep aids, benzodiazepines, MAO-A inhibitors. Non pharmacological regimens will be allowed along 1 rescue therapy such as acetaminophen ≤4,000 mg/day, ibuprofen ≤1,200 mg/day, naproxen ≤660 mg/day, or ketoprofen ≤75 mg/day. Use of paracetamol (PCM) and non-steroidal anti-inflammatory drugs (NSAIDS) will be allowed and monitored.
- Willingness to refrain from taking psychoactive substances during the study.
- Willingness to drink only alcohol-free liquids and no coffee, black or green tea, or energy drinks after midnight of the evening before the study session, as well as during the study days
- Willingness not to drive a traffic vehicle or to operate machines within 24 h after substance administration
Exclusion criteria 11
- Presence of inflammatory rheumatic diseases such as ankylosing spondylitis.
- Presence or history of psychotic, bipolar or substance use disorder as determined by the medical questionnaire, drug questionnaire and medical examination
- Current mental health diagnosis
- Previous experience of serious side effects to psychedelic drugs (anxiety or panic attacks)
- Tobacco smoking (>20 per day)
- Excessive drinking (>20 alcoholic consumptions per week)
- Psychotic disorder in first-degree relatives
- Pregnancy or lactation
- Hypertension (diastolic > 90 mmHg; systolic > 140 mmHg)
- History of cardiac dysfunctions (arrhythmia, ischemic heart disease…)
- For women: no use of a reliable contraceptive
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- We hypothesize that psilocybin will induce significant analgesic effects at 5 mg and 10 mg compared to placebo as measured by subjective measures and the outcomes of the PPT and CPT. We also hypothesize that these potential effects will be associated with variations in BDNF levels.
Secondary endpoints 1
- The secondary objective is to assess the impact of low psilocybin doses on mood, cognition, personality, autobiographical memory functioning and psychedelic experience. We will also test whether hypnotic suggestions can moderate the potential effects of psilocybin on pain perception and tolerance. Finally, we will test whether the plasma levels of inflammatory biomarkers (IL-1α, IL-1β, IL-6, IL-8, and TNF-α, C-reactive protein (CRP)) will decrease in response to psilocybin administration.
