NCT01667250

Brief Summary

The purpose of this multi-center, prospective, double-blind, randomized, sham-controlled pilot study is to study feasibility and collect preliminary clinical data related to the safety and clinical benefits of daily use of non-invasive vagal nerve stimulation with the GammaCore device for the prevention of chronic migraine, and to support the development and approval of a larger pivotal study.

  • Has had a previous bilateral, right, or left cervical vagotomy.
  • Has uncontrolled high blood pressure.
  • Is currently implanted with an electrical and/or neurostimulator device, including but not limited to cardiac pacemaker or defibrillator, 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.
