electroCore Announces Publication of PREMIUM II Trial of gammaCore (Non-Invasive Vagus Nerve Stimulation; nVNS) for the Prevention of Migraine

January 10, 2022 GMT

ROCKAWAY, N.J., Jan. 10, 2022 (GLOBE NEWSWIRE) -- electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced the publication of a peer-reviewed paper, entitled “Non-invasive vagus nerve stimulation for prevention of migraine: The multicenter, randomized, double-blind, sham-controlled PREMIUM II trial” in Cephalalgia, the official journal of the International Headache Society (IHS). The paper reports the results of a randomized, double-blind, sham-controlled trial conducted at twenty-seven sites across the United States. Originally designed and powered to randomize 400 patients, the study was closed early due to COVID-19 after enrolling 231 subjects.

The results of the study showed a decrease in the number of monthly headache days of 4.6 vs. -3.0 for sham (p=0.05) with 44.87% of subjects in the gammaCore group having greater than a 50% reduction in the number of migraine days per month compared with 26.81% for the sham group (p=0.05). Quality of life, as measured by the HIT-6 (Headache Impact scale), improved by -4.9 points vs. -2.3 for sham (p<0.05). In the subpopulation of patients diagnosed with migraine with aura, the number of headache days decreased by 5.5 days in the nVNS group compared with 2.7 in the sham group (p=0<0.05), a therapeutic gain of >100% compared to sham. These findings are consistent with previous reports on the mechanisms of action that suggest nVNS may be particularly effective in patients with migraine with aura.


Dr. Umer Najib, Associate Professor, Program Director of the Headache Medicine Fellowship Program at the West Virginia University and first author of the paper commented, “We are pleased to have added to the data that helps suggest the types of migraine patients who could likely benefit most from nVNS. The safety and tolerability of nVNS is such that it can be used as a stand-alone or adjunctive treatment, depending on the needs of the patient, and its flexibility allows health care providers to consider it for many of their patients.”

“We congratulate and thank all of the investigators, site staff, and subjects who conducted this study throughout the United States despite the challenges that arrived with COVID-19,” commented Eric Liebler, Senior Vice President of Neurology at electroCore. “With seven different indications from the FDA, gammaCore is safe and effective for many patients with primary headache, and the findings of this study highlighting the potential benefits in patients who have migraine with aura are particularly compelling.”

About gammaCoreTM
gammaCoreTM (nVNS) is the first non-invasive, hand-held medical therapy applied at the neck as an adjunctive therapy to treat migraine and cluster headache through the utilization of a mild electrical stimulation to the vagus nerve that passes through the skin. Designed as a portable, easy-to-use technology, gammaCore can be self-administered by patients, as needed, without the potential side effects associated with commonly prescribed drugs. When placed on a patient’s neck over the vagus nerve, gammaCore stimulates the nerve’s afferent fibers, which may lead to a reduction of pain in patients.

gammaCore (nVNS) is FDA cleared in the United States for adjunctive use for the preventive treatment of cluster headache in adult patients, the acute treatment of pain associated with episodic cluster headache in adult patients, and the acute and preventive treatment of migraine in adolescent (ages 12 and older) and adult patients, and paroxysmal hemicrania and hemicrania continua in adult patients. gammaCore is CE-marked in the European Union for the acute and/or prophylactic treatment of primary headache (Migraine, Cluster Headache, Trigeminal Autonomic Cephalalgias and Hemicrania Continua) and Medication Overuse Headache in adults.

gammaCore is contraindicated for patients if they:

  • Have an active implantable medical device, such as a pacemaker, hearing aid implant, or any implanted electronic device
  • Have a metallic device, such as a stent, bone plate, or bone screw, implanted at or near the neck
  • Are using another device at the same time (e.g., TENS Unit, muscle stimulator) or any portable electronic device (e.g., mobile phone)

Safety and efficacy of gammaCore have not been evaluated in the following patients:

  • Adolescent patients with congenital cardiac issues
  • Patients diagnosed with narrowing of the arteries (carotid atherosclerosis)
  • Patients who have had surgery to cut the vagus nerve in the neck (cervical vagotomy)
  • Pediatric patients (less than 12 years)
  • Pregnant women
  • Patients with clinically significant hypertension, hypotension, bradycardia, or tachycardia

Please refer to the gammaCore Instructions for Use for all of the important warnings and precautions before using or prescribing this product.
