5. Difficult-to-treat CCH with documented previous complete failure, insufficient efficacy, intolerance, or contra-indications to most preventive CH treatments among which are oral steroids or suboccipital infiltrations, verapamil, lithium carbonate and topiramate.
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 informed consent provided before enrolment
