  6. No preventive CH treatment or stable preventive CH medication for ≥ 2 weeks before enrolment. Subject agrees not to change existing treatment during the whole duration of the trial.
  7. Subject written provided before enrolment
  8. Subject willing and capable of subjective evaluation and to fill in an electronic CH diary, to understand questionnaires, and to read, understand and sign the written informed consent form.
  9. Subject willing and able to comply with study-related requirements, procedures, and visits.

Exclusion criteria

Exclusion Criteria:

  1. Other significant neurological, psychiatric, or disabling diseases which in the opinion of the investigator may interfere with the study.
  2. History of epilepsy, current treatment of epilepsy
  3. Documented history of cerebrovascular accident (CVA)
  4. Subjects suffering from a substance use disorder, as defined by (DSM) criteria. Recreational use of cannabis is allowed.
  5. Subjects at high risk of suicide/suicidal ideation in the past one year assessed with the C-SSRS
  6. Having another active implanted device such as a cardiac pacemaker, a spinal cord, peripheral nerve, sphenopalatine ganglion, or deep brain hypothalamic stimulator, and/or a drug delivery pump, etc.
  7. Cranial botulinum toxin injections in the past 3 months before enrolment. Administration of the following treatments in the last month before enrolment: monoclonal antibodies blocking calcitonin gene-related peptide transmission, suboccipital infiltrations with and/or local anaesthetics, oral steroids, radiofrequency procedure or infiltrations of the sphenopalatine ganglion, opioids WHO 3.
  8. Medication overuse headache (ICHD 3 8.2)
  9. Inability to fill out an electronic diary.
  10. Previous surgery or trauma involving the cervical spine or the occipital bone

  13. Planned pregnancy, pregnancy, or breastfeeding.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

What researchers measure

Primary outcomes

  1. Safety Evaluation of the Device [Time Frame:12 weeks / 48 weeks]

    The primary endpoint is safety and is assessed through the incidence of procedure related and/or device-related adverse events during the 12-weeks post implantation and the rate of all adverse events during the entire 48-week study period.

    Time frame: 12-weeks post implantation and through study completion at 48 weeks
