Prevention and Acute Treatment of Chronic Cluster Headache Compared to Standard of Care
A Randomized, Multicenter Study for the Prevention and Acute Treatment of Chronic Cluster Headache Using Gammacore, Versus Standard of Care.
Study Overview
Detailed Description
The study is a prospective randomized controlled multi-center investigation designed for comparison of two parallel groups, GammaCore® (active treatment) and Standard of Care, SoC, (control). The study period begins with a 2 week run-in period, followed by a 4 week comparative period when the subjects are randomized to either active treatment or control 1:1. The comparative period will be followed by a period where all subject will receive GammaCore® for 4 weeks.After the subject signed the Consent Form for participation the baseline (visit1) data will be collected. Subject will be informed how to complete the 2 week diary during the run-in period During the run-in period, all subjects will use stable SoC according to their individual prescriptions. The subject will record as CH attack regarding duration and frequency and the use of medication and oxygen.
Once subjects have finalized the run-in period, they are randomized to continue in 4 weeks comparative period. During this period, the control group continues with stable SoC and the active group is provided with a GammaCore® device for prophylactic and acute treatment in addition to the stable SoC Subjects stimulate 3 x 2 times daily as part of the prophylactic treatment regimen (cervical vagal nerve). Three 90 second stimulations are self-administered by the subject with 5 minutes between each stimulation on the right side of the neck.
This preventive stimulation regimen is performed:
- First Daily Treatment - within 1 hour of waking
- Second Daily Treatment - 7-10 hours following the first daily treatment
Acute CH attack:
- 3 x 90 second treatments consecutively at the onset of pain or symptoms. If the attack is not aborted within 15 minutes the subject should be informed to take SOC abortive medication.
- If an acute cluster headache attack is treated with the GammaCore® device, the subject will try to work within the preventive treatment window to avoid a preventive treatment in the 2-hour refractory period following the acute treatment.
A total of minimally 6 stimulations for the preventive part and as needed for the acute attacks. The active group also continues with the stable SoC during the entire 4 weeks period. Both groups record all CH attacks in the diary together with medication and oxygen use. All adverse events shall also be recorded in the diary.
The end of the 4 week comparative period marks the completion of the randomized part of the study, however all subjects are provided the option to continue to a 4 week GammaCore® treatment with the same stimulation parameter as during the 4 week randomization period. All subjects randomized to the SoC group will receive training.
During the entire study period, subjects are allowed to take rescue medication including oxygen inhalation for abortion of CH attacks. The amount and doses of the medication and oxygen are recorded in the diary.

a. At least 5 attacks fulfilling the following criteria: i. Severe or very severe unilateral orbital, supraorbital and/or temporal pain lasting 15-180 minutes if untreated ii. Headache is accompanied by at least 1 of the following:
- Ipsilateral conjunctival injection and/or lacrimation
- Ipsilateral nasal congestion and/or rhinorrhea
- Ipsilateral eyelid oedema
- Ipsilateral forehead and facial sweating
- Ipsilateral miosis and/or ptosis
- A sense of restlessness or agitation iii. Attacks have a frequency from 1 every other day to 8 per day and are not attributed to another disorder iv. Attacks recur over > 1 year without remission periods or with remission periods lasting < 1 month.
4. Has minimum mean attack frequency of 4 CH attacks per week. 5. Is able to distinguish CH from other headaches (i.e. tension-type headaches).
6. Is capable of completing headache pain self-assessments. 7. Agrees to use the GammaCore® device as intended and follow all of the requirements of the study, including follow-up visit requirements.
8. Is willing to keep all concomitant medication stable during the entire study period.

Measure Description |
Time Frame |
---|---|---|
A Change in the Frequency of Cluster Headache Attacks Per Week
Time Frame: 4 weeks
|
The primary endpoint is the reduction in mean number of CH attacks per week.
The number of CH attacks will be calculated as the sum of all attacks over the days in the run-in period and divided by the number of weeks, respectively for the last 14 days of treatment during the randomised phase.
The reduction will then be the number of CH attacks during treatment period (last 14 days of the randomized treatment period) - number of CH attacks during run-in.
