About
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
Full description
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.
