Non-Invasive Neurostimulation for the Prevention of Chronic Migraine

Completed · Not applicable · Has a placebo group

Conditions studied: Chronic Migraine

In brief

The purpose of this multi-center, prospective, double-blind, randomized, sham-controlled pilot study is to study feasibility and collect preliminary clinical data related to the safety and clinical benefits of daily use of non-invasive vagal nerve stimulation with the GammaCore device for the prevention of chronic migraine, and to support the development and approval of a larger pivotal study.
