研究概览
简要总结
The study will look at a non-invasive treatment for people suffering with chronic and episodic headaches. Study subjects will be randomized to an active treatment or an in-active treatment for 2 weeks. After the 2 weeks all subjects will continue to treat with an active treatment for an additional 2 weeks.
详细描述
The study is a prospective double blind, randomized, sham-controlled, multi-center investigation designed for comparison of two parallel groups, GammaCore® (active treatment) and a sham, (in-active) treatment. The study period begins with a 1-week run-in period, followed by a 2 week comparative period when the subjects are randomized (1:1) to either active treatment or sham (in-active) treatment. The comparative period will be followed by an open label 2 week period, where the subjects in the sham treatment group will switch in treatment assignment and receive an active treatment and the active group will continue to receive an active treatment.

结局指标
主要结局
Comparison of the Headache Pain Free Attack Rates at 15 Minutes Following the Treatment
时间窗: 2 weeks
Headache pain was collected at the beginning of the attack (all treated attacks) and 15 minutes post treatment pain free attacks. Data was collected in the patient diary.
次要结局
- Change in Disability From Baseline (Randomization) to 2 Weeks After Baseline(2 weeks)
- Patients Who Used Any Type of Rescue Medication(2 weeks)
- Mean Change of Questionnaire EQ-5D-3L (Euroqol- 5D-3L) From Baseline to After 2 Weeks Treatment(2 weeks)
- Comparison of the Headache Pain Free Attack Rates at 30 Minutes Following the Treatment(2 weeks)
