Post-marketing Clinical Trial of Elexir(Trigeminal Nerve Electrical Stimulator) for the Acute Treatment of Migraine

The purpose of this study is to evaluate the efficacy and safety of treating migraine in the acute phase by applying the acute mode (program 1) of Elexir (trigeminal nerve electrical stimulator) to patients with migraine.

Written consent is obtained from the subjects before proceeding with this study. Afterwards, the selection/exclusion criteria are checked to determine whether they are suitable for participation in the study. Subjects who meet the final selection/exclusion criteria are randomly assigned and assigned to the test group or control group in a 1:1 ratio, clinical research coordinator will provide the subject with Investigational device to use at home and migraine diary, AE reporting form If migraine occurs within 8 weeks at home, the subject applies a investigational device (test device or control device) for 1 hour. A migraine diary is written after a migraine occurs and before starting a investigational device.

A migraine diary is written 1 and 2 hours after the start of application of the investigational device, and acute migraine treatment medications can be taken from that point on. Then, the subject writes migraine diary again 24 hours after starting to apply the investigational device.

Subjects who have applied the investigational device must visit the institution within 7 days after application and return the investigational device and the migraine headache.

If a subject does not occure a migraine within an 8-week period, subject must visit the institution and return the investigational device and migraine diary.
