A Phase III Trial of e-TNS for the Acute Treatment of Migraine

A Phase III Randomized, Double-blind, Sham-controlled Trial of e-TNS for the Acute Treatment of Migraine (The TEAM Study)

The main objective of this study is to have Phase III evidences of the efficacy of the Cefaly® Abortive Program device used at home for 2 hours to treat a migraine attack. This randomized, double-blind, sham-controlled trial will study the abortive treatment of migraine using the Cefaly® Abortive Program device.

The main objective of this study is to have Phase III evidences of the efficacy of the Cefaly® Abortive Program device used at home for 2 hours to treat a migraine attack, as triptans are generally used. That is to say having randomized, double-blind, sham-controlled data of the efficacy and safety of the Cefaly® Abortive Program device in the abortive treatment of acute migraine as measured by 2-hour pain freedom, pain relief and migraine-associated symptoms freedom, plus evolution of these measurements for 24 hours after the beginning of the treatment session.
