Non-Invasive Neurostimulation For the Relief of Symptoms Associated With Migraine

Non-Invasive Neurostimulation of the Vagus Nerve With the GammaCore Device For the Relief of Symptoms Associated With Migraine

The purpose of this pilot study is to assess feasibility and clarify the design of future study(ies) to support marketing approval of the GammaCore™ device for the treatment and/or prevention of migraine symptoms.

• Has a history or baseline ECG that identifies the presence of a clinically significant unstable cardiac arrhythmia, second degree heart block type II, history of ventricular tachycardia or ventricular fibrillation, or known cardiac syndromes that may be associated with increased risk of sudden death in otherwise healthy people.
• Has had a previous bilateral or right cervical vagotomy.
• Has a clinically significant irregular heart rate or rhythm.
• Has uncontrolled high blood pressure.
• Is currently implanted with an electrical and/or neurostimulator device, including but not limited to cardiac pacemaker, vagal neurostimulator, deep brain stimulator, spinal stimulator, bone growth stimulator, or cochlear implant.
• Has a history of carotid endarterectomy or vascular neck surgery on the right side.
• Has been implanted with metal cervical spine hardware or has a metallic implant near the GammaCore™ stimulation site.
• Has a recent or repeated history of syncope.
• Has a recent or repeated history of seizure.
• Has a history or suspicion of narcotic abuse.
• Takes medication for acute headaches more than 10 days per month.
• Is pregnant, nursing, thinking of becoming pregnant in the next 3 months, or of childbearing years and is unwilling to use an accepted form of birth control.
• Is participating in any other therapeutic clinical investigation or has participated in a clinical trial in the preceding 30 days.
• Belongs to a vulnerable population or has any condition such that his or her ability to provide informed consent, comply with follow-up requirements, or provide self-assessments is compromised (e.g., homeless, developmentally disabled, prisoner).
• Is a relative of or an employee of the investigator or the clinical study site.
