As discussed on the phone, we require patients to:

  • Ages 18+
  • Migraine attacks present for more than 1 year from the Screening Visit
  • Age of onset prior to 50 years of age
  • Migraine attacks lasting about 4–72 hours, if untreated
  • Experience 4-14 migraines for the last 3-months
  • Within the last 10 years, you have had inadequate response, to oral migraine-preventive medications (that are across 2-4 categories).
    • At least one of these must be either the medication not working well enough or you cannot tolerate after trying it.

We will print these out for you on the day of your appointment so all you need to do is bring your study partner and a list of any medications you are currently taking. Please let us know if you have had any changes to your medications recently as this may mean you cannot join the trial.
