  • Documented chronic cluster headache for at least 1 year as per ICHD-3 criteria
  • Attack frequency of ≥ 4 attacks per week for ≥ 4 weeks before enrolment
  • Documented failure of verapamil (failure meaning ineffective, provoked unacceptable side-effects or contra-indicated)
  • Stable on preventive treatment for at least two weeks prior to enrolment.
  • Agree to refrain from starting new prophylactic cluster headache medication or other preventive treatments, from 4 weeks before entering the baseline period throughout the duration of the study

  • Concomitant neuromodulation, except tVNS
  • Previous failure to any implantable neuromodulation device for neurovascular headache
  • Have an existing Active Implantable Medical Device nearby the implant location (e.g. DBS, cochlear implant, …)
  • Metal implants in the skull (e.g. skull plates, seeds) nearby the implant
  • Have a pacemaker or implantable cardioverter defibrillator (ICD)
  • Suboccipital infiltrations with steroids and/or local anaesthetics or use of oral steroids in the past 3 months
  • Use of botulinum toxin injections in the past 12 weeks
