Brief Summary:

This is a randomized study for the prevention and acute treatment of migraine using open label nVNS and standard of care versus standard of care.

.


Condition or disease Intervention/treatment Phase
Migraine Device: non-invasive vagus nerve stimulation Not Applicable

Detailed Description:

A randomized study for the prevention and acute treatment of migraine using open label nVNS and standard of care versus standard of care.

Eligible subjects will participate in a 4 week run-in period after which they will be randomized (1:1) to either nVNS and standard of care (nVNS group) or standard of care (SOC group) for 12 weeks. The nVNS group will use the nVNS device preventatively and acutely for the treatment of migraine. The SOC group will continue to use their regular standard of care migraine treatment medications for the duration of the 12 week randomized period.

Primary Outcome Measures :
  1. Reduction in number of migraine days during the last four weeks in the twelve-week randomized period compared with the four-week run-in period [ Time Frame: The last four weeks in the randomization period compared to the four week run-in period. ]
    Reduction in number of migraine days during the last four weeks in the twelve-week randomized period compared with the four-week run-in period


Secondary Outcome Measures :
  1. Reduction in number of headache days during the last four-weeks in the twelve-week randomized period compared to the four-week run-in period [ Time Frame: The last four weeks in the randomization period compared to the four week run-in period. ]
    Reduction in number of headache days during the last four-weeks in the twelve-week randomized period compared to the four-week run-in period

  2. Reduction in number of migraine days and headache days (separately) [ Time Frame: 12 week randomised period ]
    Reduction in number of migraine days and headache days (separately) during weeks 1 through 4, 5 through 8 in the 12 week randomised period

  3. Rate of responders for the nVNS group compared to the standard of care group. [ Time Frame: The last four weeks in the randomization period compared to the four week run-in period. ]
    Rate of responders (mean reduction in migraine days during the last four weeks in the twelve-week randomization period compared to the four-week run-in period dichotomized as <25% vs. ≥25%, <50% vs ≥50% and <75% vs ≥75%, separately) for the nVNS group compared to the standard of care group.

  4. Acute treatment response for nVNS and standard of care therapies [ Time Frame: 12 week randomised period ]
    Acute treatment response for nVNS and standard of care therapies at 30, 60 and 120 minutes post-treatment, for all treated migraine attacks in the twelve-week randomized period

  5. Consistency of response [ Time Frame: 12 week randomised period ]
    Consistency of response as defined as the percentage of subjects who achieve treatment response in 25%, 50% and 75% or greater of their attacks, in subjects treating at least two attacks, for nVNS and standard of care therapies for all treated migraine attacks during the randomized period

  6. Safety and tolerability of nVNS as measured by adverse events [ Time Frame: 12 week randomised period ]
    Safety and tolerability of nVNS as measured by adverse events


Other Outcome Measures:
  1. Change in acute headache medication use [ Time Frame: 12 week randomization period compared to the four week run-in period ]
    Change in acute headache medication use (proportion of attacks with acute medication use prior to or at 120 minutes post-treatment) for all treated attacks in the twelve-week randomized period compared to the four week run-in period in the nVNS group

  2. Presence or absence of nausea, vomiting, photophobia, phonophobia [ Time Frame: 12 week randomised period ]
    Presence or absence of nausea, vomiting, photophobia, phonophobia at 0, 30, 60 and 120 minutes post treatment for nVNS and standard of care therapies for all treated migraine attacks in the randomized period

Criteria

Inclusion Criteria:

  • Is 18 years of age or above.
  • Has been previously diagnosed with episodic or chronic migraine (with or without aura) in accordance with the ICHD-3 Classification criteria.
  • Experience at least 6 and no more than 24 headache days per month and a minimum of 4 migraine attacks per month (over the last 3 months).
  • Has age of onset of migraine less than 50 years old.
  • Stable regime for any migraine preventative medications for the last 3 months and agrees to maintain stable regime for duration of the study.
  • Agrees to and in clinician opinion is able to use the nVNS device as intended, follow all of the requirements of the study including follow-up visit requirements, record required study data in the subject dairy, and other self-assessment questionnaires.
  • Availability of internet/Web access for Web-based e-diary completion
  • Is able to provide written Informed Consent.

Exclusion Criteria:

  • Requires use of oral or injectable steroids for concomitant medical condition that in the opinion of the investigator will interfere with the study.
  • Has a history of any intracranial aneurysm, intracranial haemorrhage, brain tumour or significant head trauma.
  • Has a structural abnormality at the nVNS treatment site (e.g. lymphadenopathy previous surgery or abnormal anatomy).
  • Has pain at the nVNS treatment site (e.g. dysesthesia, neuralgia and/or cervicalgia).

  • Has failed an adequate trial (two months or greater) of at least 3 classes of a drug therapy for the prophylaxis of migraine.
  • Is pregnant or of childbearing years and is unwilling to use and accepted form of birth control (condom or contraceptive pill).
  • 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 the follow-up requirements, or provide self- assessments is compromised (e.g. homeless, developmentally disabled and prisoner).
  • Has previously used the gammaCore device within the last 3 months.
