Chronic Migraine

Brief summary

An non controlled, long term, multi center investigation

Detailed description

Subjects who provided written informed consent and are eligible for the study will be asked to complete a daily diary for 4 weeks during the screening period. In the diary the subjects will record headache and migraine days, any changes in their health, and concomitant medications they may be using. The data collected in the diary during this screening period will be used as Baseline for the performance assessments. A non-controlled, long term, multi-center investigation for symptom improvement in subjects suffering headache and migraine attacks. During the run-in (baseline) period and through the whole study the subjects will continue using their existing prescribed or over the counter (OTC) treatments. Following the run-in period (4 weeks) the subjects will be treated six times within a period that is approximately 6 weeks. The first treatment will be given the first day after the run-in period. During 12-month follow-up period (from the time of the first treatment), subjects will be treated when needed but a maximum of 14 treatments.

Interventions

Treatment is 10 minutes in each nasal cavity. Totally 2 x 10 minutes per treatment.

Design outcomes

Primary

MeasureTime frameDescription
To evaluate the efficacy of intranasal kinetic oscillation stimulation using the Chordate System S220 on monthly headache days with moderate to severe intensity after approx 6 weeks of treatment.Baseline to 6 weeksChange in proportion of days with headache with moderate to severe intensity compared to the four week period starting the day after the third treatment Headache days are collected in electronic diary (eDiary)

Secondary

MeasureTime frameDescription
To evaluate the incidence and severity of adverse events (AEs) and adverse device effects (ADEs) following treatment with the Chordate System S220.Baseline to 12 monthAll adverse events (AEs) and adverse device effects (ADEs) incidence and severity following treatment with KOS
Number of patients who are respondersBaseline to 12 monthResponders are classified as responder (less migraine/headache days) or non-responder (same or worsening of migraine/headache days). A responder is a patient who has decrease of headache/migraine days whilst a non responder had no or the same number of headache/migraine days
To evaluate the efficacy of treatment with KOS on monthly migraine days (regardless of intensity) Description: Migraine days are collected in an eDiary.Baseline to 12 monthMigraine days is collected in an eDiary.
Mean change in Headache Impact Test (HIT-6)Baseline to 12 monthHIT-6 consist of 6 questions HIT-6 with scores from 6 to 13 where 13 is worst case per question so lower score is better outcome than high scores.
Mean change in Subject global severityBaseline to 12 monthPatient Global severity is a scale with four (4) scores, where normal (0) is the lowest and show no problems whilst severe (3) is the worst score 0. Normal 1. Mild 2. Moderate 3. Severe
Number of patients who decrease use of abortive medicationBaseline to 12 monthIntake of abortive medications are registered in eDiary and will be calculated on patient level
