简要总结
This study is a prospective, multi-centre, randomised, double-blind, sham-controlled investigation designed for comparison of two parallel treatment groups: gammaCore (active nVNS treatment) and a Sham device (control treatment), for the acute treatment of migraine attacks
详细描述
Period 1: 4-week observational run-in period; no stimulation treatment. Subjects use standard of care (SoC) medication to treat their migraine attacks, according to their individual prescriptions.
Period 2: 4-week randomized/controlled period. After the run-in period, subjects are randomized (1:1) to receive either an nVNS device or a sham device to treat up to 5 migraine attacks.
Period 3: 4-week open-label (active treatment) period. After the randomized period, subjects continue to the open-label period where all subjects receive an active gammaCore device to treat up to 5 migraine attacks.

- •Has been previously diagnosed with migraine (with or without aura) in accordance with the ICHD-3 Beta classification criteria.
- •Age of onset of migraines < 50 years old.
- •Experiences between 3-8 migraine attacks per month of moderate or severe intensity, and less than 15 headache days per month over the last 6 months.
- •Is able to distinguish migraine headaches from other headaches (e.g. tension type headache).
- •Agrees to withhold usual acute migraine medications until 2 hours after stimulation treatment with the study device.
- •Agrees not to initiate new or change existing migraine prophylaxis medication for the duration of the study, or receive nerve blocks or injections.
- •Agrees not to initiate new or change existing prophylactic medication for indications other than migraine that in the opinion of the Investigator may interfere with the study objectives (e.g. antidepressant, anti-convulsant, beta blockers, etc).
- •Has internet/web access for web-based e-Diary completion.
- •Agrees to use the study device as intended, comply with all study requirements including treatment, follow-up visits, record required study data in the subject diary, and complete study self-assessment questionnaires.
- •Is able to provide written informed consent.
排除标准
- •Experiences ≥ 15 headache days per month, including migraine, tension type headache, medication overuse headache, and other types of headache as defined in the ICHD-3 Beta classification.
- •Has a known history or suspicion of secondary headache.
- •Has previous diagnosis of medication overuse headache (MoH), which has reverted to episodic migraine within the last 6 months.
- •Has had surgical intervention for migraine prevention.
- •Has had a cervical vagotomy.
- •Has a structural abnormality (e.g. lymphadenopathy, neoplasm, previous surgery or abnormal anatomy), or pain (e.g. dysesthesia, neuralgia and/or cervicalgia) at the stimulation treatment site.
- •Has other significant pain problem (e.g. cancer pain, fibromyalgia or other head or facial disorder) that in the opinion of the Investigator may confound the study assessments.
- •Is currently implanted with an electrical and/or neurostimulator device (e.g. cardiac pacemaker or defibrillator, vagal neurostimulator, deep brain stimulator, spinal stimulator, bone growth stimulator, cochlear implant, sphenopalatine ganglion stimulator, or occipital nerve stimulator).
- •Has been implanted with metal cervical spine hardware or has a metallic implant near the stimulation treatment site.
- •Has failed an adequate trial (two months or greater) of at least 3 classes of a drug therapy for acute treatment of migraine.
- •Has initiated new, or changed existing medications for migraine prophylaxis in the previous 2 months.
- •Is using marijuana (including medical marijuana) for any indications, more than twice a month.
- •Currently takes simple analgesics or non-steroidal anti-inflammatory drugs (NSAIDS) greater than 15 days per month, or triptans, ergots or combined analgesics greater than 10 days per month.
- •Currently takes opioids greater than 2 days per month for headache relief or body pain.
- •Has undergone nerve block (occipital or other) in the head or neck within the last 2 months, or Botox injections within the last 6 months.
- •Has a concomitant medical condition that will require oral or injectable steroids during the study.
- •Has a history of intracranial aneurysm, intracranial haemorrhage, brain tumour or significant head trauma.
- •Has known or suspected severe cardiac disease (e.g. symptomatic coronary artery disease, prior myocardial infarction, congestive heart failure(CHF), cerebrovascular disease (e.g. prior stroke or transient ischemic attack symptomatic carotid artery disease, prior carotid endarterectomy or other vascular neck surgery), or uncontrolled high blood pressure (systolic >160, diastolic >100 after 3 repeated measurements within 24 hours).

- •Is pregnant or thinking of becoming pregnant during the study period, or of childbearing years and is unwilling to use an accepted form of birth control.
- •Is a relative or employee of the Investigator or the clinical study site.

结局指标
主要结局
Number of Participants With Treatment Response - No Pain
时间窗: 2 hours post-treatment
The primary objective is to compare the treatment response for nVNS and Sham therapies at two hours post-treatment, for the first treated migraine attack during study Period 2. Treatment response is defined as no pain at 2 hours post-treatment and no rescue medication use by 2 hours post-treatment.
次要结局
- Number of Participants With Treatment Response - No Pain or Mild Pain(2 hours post-treatment)
- Number of Participants With Absence of Nausea/Vomiting, Photophobia, Phonophobia(2 hours post-treatment study - period 2 (each study period was 4 weeks))
- Number of Migraine Attacks With Treatment Response 'No Pain' in Study Period 2 All Attacks(30, 60, 120 minutes; Study Period 2 (each study period was 4 weeks))
- Number of Participants With Treatment Response no Pain or Mild Pain at 24 and 48 Hours.(24 and 48 hours post-treatment)
