A clinical study to evaluate the prophylactic effect of non-invasive vagal nerve stimulation for the prevention of chronic migraine completed enrollment last week. The study, which is being sponsored by electroceutical healthcare company electroCore, involves 60 patients across six US sites.After an initial one month period, during which headache frequency data will be collected, the patients, all of whom experience migraine headaches on more than 15 days per month, will be randomized into two groups. One group will use an active device and the other a sham device for a period of two months. All patients will then be provided with the active treatment device for a period of six months. Throughout the study, patients will record the number of headache days and the severity of the headaches experienced. The full results are expected in the second quarter of 2014. This study, which is part of one of the largest global clinical programs currently being run in headache, is an FDA approved IDE pilot, double blind, randomized, sham controlled trial. The treatment being studied is electroCore’s gammaCore vagus nerve stimulation therapy, which is delivered by placing the gammaCore against the neck over the vagus nerve – where the carotid pulse is located. Prior evidence shows that the active device will stimulate the afferent fibres of the vagus nerve which project into the brain stem, where the signal causes the release of inhibitory neurotransmitters in the brain, including GABA, serotonin, and norepinephirine. electroCore’s Chief Operating Officer, Frank Amato commented, “We are grateful to the physicians, sites, and patients with chronic migraine with whom we are working, and pleased that they have now completed the enrollment of this important trial. Next, we look forward to the completion of the follow up phase, and to the opportunity to analyze the data from this study, which extends over a nine month period. This trial is an important piece of the larger multi-trial global program across several primary headache conditions, all of which should read out over the next 12 to 18 months.”

 IDE means investigational device exemption granted by the FDA for trials of devices which are not yet approved. “Double blind” means neither patient nor doctor administering the trial are aware of which device is sham and which is active. “Sham controlled” means in this trial that half of the patients are using a device that is not active in stimulating the vagus nerve “Randomized” means that assignment of subjects to receive active or sham therapy is done randomly.
