An open pilot study, non-controlled, single center investigation.
Detailed description
An open pilot study, non-controlled, single center investigation. The study consists of a 4-week screening period, a 6-week treatment period, and a 12 week follow-up period. 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. Subjects who completed the screening period and continue to meet the eligibility criteria after review of diary entries by the investigator will receive treatment. The subjects will receive 6 treatments with the Chordate System S220 at weekly intervals at the site (Day 0 to 35; treatment Visit \[V\] 1 to 6) and continue to maintain a daily diary. After completion of the 6-week study treatment period (V1 to V6), subjects will be treated monthly and followed up for another 12 weeks. The final visit will be performed on Day 125, 12 weeks after the last study treatment. During the 12-week follow-up, the subjects will continue to complete a daily diary.
Interventions
Treatment is 10 minutes in each nasal cavity. Totally 2 x 10 minutes per treatment.

Male or female aged between 18 and 70 years (inclusive) at the time of providing informed consent. 3. Diagnosed as suffering from chronic migraine with or without aura (≥15 headache days per month including at least 8 migraine days for more than 3 months before screening) according to the International Headache Society classification (International Classification of Headache Disorders III); 4. Migraine onset before the age of 50 years. 5. Reported history of migraine for at least 1 year before screening. 6. If subjects are on a preventive treatment at the time of screening, this must have been stable over the preceding 3 months. 7. If subjects are on preventive treatment at the time of screening, they have to be able and willing to maintain current preventive treatment regimen (no change in type, frequency or dose) from screening to end of follow- 8.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean change in headache days | baseline to 6 weeks | Change in headache days with moderate to severe intensity after 6 weeks of treatment. Headache days are collected in eDiary |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse events (AEs) and adverse device effects (ADEs) | Baseline to 12 weeks | All adverse events (AEs) and adverse device effects (ADEs) incidence and severity following treatment with the Chordate System 220 |
| Number of patients who are responders | baseline to 12 weeks | Responders are classified as responder (less migraine/headache days) or non-responder (same or worsening of migraine/headache days). A respondes is a patient who has decrease of headaches/migraine days whilst a non responder had no or the same number of headache/migraine days |
| Number of patients who decrease use of abortive medication | baseline to 12 weeks | Intake of abortive medications are registred in eDiary and will be calculated on patient level |
| Mean change in Migraine days Mean change of migraine days, responder rate, use of abortive medication, health-related quality of life and disability, and patient's global impression of severity 12 weeks (90 days) | Baseline to 12 weeks | Migraine days is collected in an eDiary. |
| Mean change in Headache Impact Test (HIT-6) | baseline to 12 weeks | HIT-6 consist of 6 questions HIT-6 with scores from 6 to 13 where 13 is worst case per question so lower score means less problems |
| Mean change in Subject global severity | baseline to 12 weeks | Patient 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 |
| Mean change in headache days | week 6-12 | Change in headache days with moderate to severe intensity from eDiary |
| Mean change in Hospital Anxiety and Depression Scale (HADS) | baseline to 12 weeks | HADS is a scale with 7 questions related to anxiety and 7 questions related to depression Anxiety can have 0-21 points (lower score means no anxiety) and Depression 0-21 points (higher score means no depression) |
