NCT04280055

Brief Summary

The purpose of this study is to investigate the prophylactic effects of psilocybin in chronic cluster headache. Subjects will receive a low dose of psilocybin during 3 sessions spaced by one week. Subjects will maintain a headache diary prior to, during, and after the administrations in order to document headache frequency, intensity and duration. Subjects will undergo a fMRI scanning before the first and after the last psilocybin session.

Outcome Measures

Primary Outcomes (2)

  • Headache frequency

    Change in headache frequency in number of attacks/week

    Week 6-10 (post drug observation) compared to week 0-4 (baseline observation)

  • Resting state FC fMRI analyses

    Resting state FC fMRI analyses, including hypothalamic FC, comparing baseline and rescan, comparison with healthy control sample, and evaluation of correlation between headache frequency changes and FC changes.

    Day 1 of first psilocybin session to 1 week after last psilocybin session (3 weeks)

Secondary Outcomes (12)

  • Proportion of reduced frequency

    Week 6-10 (post drug observation) compared to week 0-4 (baseline observation)

  • Headache intensity

    Week 6-10 (post drug observation) compared to week 0-4 (baseline observation)

  • Need of acute therapy

    Week 6-10 (post drug observation) compared to week 0-4 (baseline observation)

  • Sideeffects

    Whole observation period (10 weeks)

  • Remission

    Day 1 after first psilocybin session until 12 month follow up (1 year).

  • +7 more secondary outcomes

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age between 18 and 65
  • A diagnosis of chronic cluster headache according to IHCD-III.
  • Ability to separate cluster headache attacks from other types of headache.

You may not qualify if:

  • A history of using a serotonergic hallucinogen for CH.
  • Participation in any clinical trials within 30 days preceding study enrollment.
  • Use of other prophylactic CH medication within the last two weeks.
  • Current use of drugs suspected to interfere with treatment (e.g. antipsychotic medication) or to be hazardous in combination with psilocybin.
  • Presence of other trigeminal autonomic cephalalgias.
  • Known hypersensitivity/allergy to multiple drugs (including psilocybin).
  • A history or presence of any medical and psychiatric condition that might render patient unsuitable for participation.
  • Present or previous manic or psychotic disorder or critical psychiatric disorder.
  • Current drug or alcohol abuse.
  • MRI Contraindications.
  • Pregnancy or breastfeeding
