Details and patient eligibility

About

The purpose of this feasibility study is to gather preliminary information on the safety and effectiveness of patient self-administration of a noninvasive neurostimulation of the vagus nerve using the GammaCore device for the treatment of pain and allodynia symptoms associated with acute migraine in adults.

Full description

This is a prospective, non-randomized, unblinded, multi-center feasibility study; 25 subjects will be enrolled at up to 5 study centers. Subjects considered for participation in this study will be those who have a diagnosis and documented history at least 2 episodes of acute headache pain and allodynia associated with migraine per month, but no more than 15 headache days per month. Subjects may, but are not required to experience prodromal symptoms, such as aura, or concomitant photophobia, phonophobia, or nausea with their migraine episodes, so long as their headaches meet the IHS-Classification criteria for migraine. Subjects will be screened for study eligibility and consented for study participation at presentation to the headache clinic. Once consented, subjects will be trained by the Investigator(s) at the study center on at-home use of the GammaCore device and on study data collection and other requirements.

Each subject enrolled in this study will treat up to 3 migraine headaches at home over a period of up to 6 weeks.

From the onset of headache pain, the subject will withhold usual migraine medications and wait until the pain becomes moderate or severe, or 30 minutes, whichever is sooner. At that point, the subject will self-administer a first stimulation treatment, which is 90 seconds in duration.

Has age of onset of migraine less than 50 years old.
Is able to distinguish migraines from other headaches (e.g. tension headache).
Agrees to withhold usual migraine medications until after stimulation treatment with the GammaCore device.
Agrees to follow all of the requirements of the study, including follow-up visit requirements, and is sufficiently trained with respect to the operation of the GammaCore device and the data collection procedures.
Agrees to report use of the GammaCore device, study data, and any adverse device effects to the study center within 24 hours of treatment(s), and agrees to schedule an office visit 4-10 days after the third and final treatment, or when 6 weeks has passed, whichever comes first.
Is able to give written Informed Consent, or his/her legally authorized representative is available to give written Informed Consent.

Exclusion criteria

Has a history of aneurysm, bleed, brain tumors or significant head trauma.
Has a lesion (including lymphadenopathy) at the therapy head placement site.
Has known or suspected severe atherosclerotic cardiovascular disease, carotid artery disease (e.g. bruits or history of TIA or CVA) or congestive heart failure (CHF).
Has a history of epilepsy.
Has suspected or confirmed sepsis, or infection.
Has a clinically significant irregular heart rate or rhythm.
Is receiving pressors to maintain blood pressure.
Has a history of syncope.
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 been implanted with metal cervical spine hardware.
Has a history of carotid endarterectomy or vascular neck surgery on the right side.
Has a condition that would interfere with headache pain self-assessment.
Is pregnant or is thinking of becoming pregnant in the next 6 weeks.
Is participating in any other therapeutic clinical investigation or has participated in a clinical trial in the preceding 30 days.
Takes medication for acute headaches more than 10 days per month.
Has a history or suspicion of substance abuse
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).
