Trial Outcomes & Findings for RCT of Non-Invasive Vagus Nerve Stimulation (nVNS) With gammaCore®, for the Acute Treatment of Migraine Attacks (NCT NCT02686034)

NCT ID: NCT02686034

Last Updated: 2019-08-02

Results Overview

The primary objective is to compare the treatment response for nVNS and Sham therapies at two hours post-treatment, for the first treated migraine attack during study Period 2. Treatment response is defined as no pain at 2 hours post-treatment and no rescue medication use by 2 hours post-treatment.

Measure
gammaCore-S
Treatment of up to 5 migraine attacks with the Active gammaCore-S non-invasive vagus nerve stimulator device which delivers a mild electrical signal in the vicinity of the vagus nerve gammaCore-S: At onset of migraine pain, the subject self-administers a bilateral treatment with the gammaCore nVNS device (2 minutes on the right side, and 2 minutes on the left side). If their headache pain has not improved after 15 minutes, they administer another bilateral treatment. If they are not pain-free at 2 hours, they have the option to administer a third bilateral treatment, or take their usual rescue medication.
gammaCore-S Sham
Treatment of up to 5 migraine attacks with the Sham gammaCore-S non-invasive vagus nerve stimulator device which delivers a mild electrical signal in the vicinity of the vagus nerve gammaCore-S Sham: At onset of migraine pain, the subject self-administers a bilateral treatment with the gammaCore nVNS Sham device (2 minutes on the right side, and 2 minutes on the left side). If their headache pain has not improved after 15 minutes, they administer another bilateral treatment with the Sham device. If they are not pain-free at 2 hours, they have the option to administer a third bilateral treatment with the Sham device, or take their usual rescue medication.

Treatment of up to 5 migraine attacks with the Sham gammaCore-S non-invasive vagus nerve stimulator device which delivers a mild electrical signal in the vicinity of the vagus nerve gammaCore-S Sham: At onset of migraine pain, the subject self-administers a bilateral treatment with the gammaCore nVNS Sham device (2 minutes on the right side, and 2 minutes on the left side). If their headache pain has not improved after 15 minutes, they administer another bilateral treatment with the Sham device. If they are not pain-free at 2 hours, they have the option to administer a third bilateral treatment with the Sham device, or take their usual rescue medication.

Treatment effect on quality of life: EQ-5D-5L is assessed at end of the run-in period and at the end of each 4-week period for nVNS and sham therapies. EQ-5D-5L descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1 = no problems, 2 = slight problems, 3= moderate problems, 4 = severe problems and 5 = extreme problems. Subjects indicate health state by ticking choosing appropriate statement in each dimension. The 5 dimensions scores are combined into a score, where a lower score indicates less problems. Scores across all 5 dimensions are averaged resulting in a total theoretical score of 1 to 5 with lower scores indicating less problems

Timeframe: Study Period 2 (4 weeks)

Population: Intent to treat

After the first treated attack and at the end of the double blind period (period 2) subjects were asked to guess if they were had received 'gammaCore-S', ''sham' or 'do not know'. Bang blinding index estimated are presented for the gammaCore-S and sham. Bang Blinding Index shows the success of blinding. The blinding index proposed is scaled to an interval of -1 to 1, 1 being complete lack of blinding, 0 being consistent with perfect blinding and -1 indicating opposite guessing which may be related to unblinding. A score of one means they guess correctly, -1 incorrectly. If the bang index includes 0 it indicates that the guesses were consistent for the sham and active and the study was appropriately blinded

Population: Intent to treat

The HIT-6 measures impact of headaches on ability to function at work, at home and in social situations. Subjects answer 6 questions about ability to function and normal daily life and for each question they rate the impact of their headaches as 'never' (6 points) or 'rarely' (9 points) or 'sometimes' (10 points) or 'very often' (11 points) or 'always' (13 points). Minimum score = 36, maximum score = 78. Higher score is worse and lower score is better quality of life
