Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparison of the Headache Pain Free Attack Rates at 15 Minutes Following the Treatment	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.	2 weeks
Secondary	Change in Disability From Baseline (Randomization) to 2 Weeks After Baseline	Mean difference of scores on a 5 step disability scale. Disability was measured at baseline and after the randomization phase (2 weeks later). Lowest score is 1 and is better than the higher score at 5 that is the worst. An increase, higher scores, means worsening.; minor; minor/moderate; moderate; moderate/severe; severe	2 weeks
Secondary	Mean Change of Questionnaire EQ-5D-3L (Euroqol- 5D-3L) From Baseline to After 2 Weeks Treatment	EQ-5D-3L descriptive system comprises 5 dimensions: mobility, self-care, activity, pain and anxiety. Each dimension has 3 levels: 1 = no problems, 2 = moderate problems, 3=extreme problems. Subjects indicate health state by ticking choosing appropriate statement in each dimension and a VAS scale (Overall health) from 0-100 mm where higher score is better (100) than lower score (0).; Patients completed the EQ-5D-3L at baseline (the start of the randomized period and at 2 weeks).	2 weeks
Secondary	Patients Who Used Any Type of Rescue Medication	Following treatment at 15 minutes, patients recorded use of any rescue medication(s) in the diary'	2 weeks
Secondary	Comparison of the Headache Pain Free Attack Rates at 30 Minutes Following the Treatment	The headache pain was collected at the beginning of the attack and 30 minutes post treatment in the patient diary.; The number of pain free (no pain) attacks are compared to all attacks treated	2 weeks
