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.

Primary Outcome Measures :
  1. Safety - Number of Participants With Adverse Events [ Time Frame: Up to 8 weeks - duration of the Randomized period ]
    Safety was assessed by collecting Adverse Effects


Secondary Outcome Measures :
  1. Mean Change in Headache Days [ Time Frame: Run-in period (4 weeks no treatment) and Randomized period (8 weeks) ]
    Mean change in headache days. Change between 4 week run in period to the 8 weeks randomized period.

  2. Total Number of Headache Days Per Arm With Peak Severity of Mild, Moderate, or Severe [ Time Frame: Run-in (4 weeks no treatment) and Randomized (8 weeks) ]
    Peak severity per headache day was reported each headache day in the subject diary. Pain was reported as mild, moderate or severe. Whereas as mild = least severe and severe = most severe.

  3. Use of Pain Relief Medication [ Time Frame: Randomized period - 8 weeks ]
    All abortive headache medication taken during randomized period

  4. Mean Change in Quality of Life Short Form Survey (SF-12) [ Time Frame: Run-in (4 weeks) and Randomized period (8 weeks) ]

    The Quality of Life Short Form Survey (SF-12) is a multipurpose short form survey with 12 questions that are combined, scored and weighted to create two scales that provide glimpses into mental and physical functioning and overall health-related-quality of life. The SF-12 is weighted and summed to provide easily interpretable scales for physical and mental health. Physical and Mental Health Composite Scores (PCS & MCS) are computed using the scores of the twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.

    SF-12 were recorded in the subject diary at the Phase 1 follow-up visit (week 4) and during Phase 2 randomized period at week 4 and week 8.

  • Is able to provide written Informed Consent
  • Agrees to refrain from changing the type or dosage of any prophylactic medications for indications other than chronic migraine that in the opinion of the clinician may interfere with the study

Exclusion Criteria:

  • Has a lesion (including lymphadenopathy), dysaesthesia, previous surgery or abnormal anatomy at the GammaCore treatment site.
  • Has known or suspected severe atherosclerotic cardiovascular disease, severe carotid artery disease (e.g. bruits or history of TIA or CVA), congestive heart failure (CHF), known severe coronary artery disease or recent myocardial infarction.
  • Has an abnormal baseline ECG (e.g. second and third degree heart block, atrial fibrillation, atrial flutter, recent history of ventricular tachycardia or ventricular fibrillation, or clinically significant premature ventricular contraction)
  • 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.
  • Has a known history or suspicion of substance abuse or addiction.
  • Has had a surgery for migraine prevention.
  • Has received Botox injections for migraine prevention within the past 6 months.
  • Has taken medications for migraine prophylaxis in the previous 30 days.
  • In the opinion of the investigator/research staff the subject is incapable of operating the GammaCore device as intended and performing the data collection procedures.
  • Is pregnant, nursing, thinking of becoming pregnant in the next 9 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.
