electroCore Announces Department of Veterans Affairs Sponsored Study of Non-Invasive Vagal Nerve Stimulation (nVNS) in Mild Traumatic Brain Injury (mTBI) and Post-Traumatic Stress Disorder (PTSD)
As outlined in the study protocol, the conflicts in
The study, which plans to enroll 100 veterans, is designed to assess the clinical and physiological effects of nVNS in patients with mTBI and PTSD. The study’s primary outcome measures include assessments of the veterans’ clinical improvement, several objective measurements of brain activity, and changes in the levels of the inflammatory cytokine interleukin-6 (IL6) in response to stress.
mTBI and PTSD disorders have a high degree of overlap, making diagnostic evaluation complex. It is estimated that up to 56% of mTBI patients have co-morbid PTSD,1, 4 and 18% of veterans of the conflicts in
“We are very pleased to be selected to participate in this important study,” said Peter Staats, MD, Chief Medical Officer of electroCore. “This study builds on recent published work by

gammaCore™ (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 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, the acute treatment of pain associated with migraine headache in adult patients, and the prevention of migraine 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. In 2019, NICE published an evidence-based Medical Technology Guidance document recommending the use of gammaCore for cluster headache within NHS England.
- Safety and efficacy of gammaCore have not been evaluated in the following patients:
- 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
- Pregnant women
- Patients with clinically significant hypertension, hypotension, bradycardia, or tachycardia
- Patients should not use gammaCore 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 their neck
- Are using another device at the same time (e.g., TENS Unit, muscle stimulator) or any portable electronic device (e.g., mobile phone)
In the US, the FDA has not cleared gammaCore for the treatment of pneumonia and/or respiratory disorders such as acute respiratory stress disorder associated with COVID-19.
Please refer to the gammaCore Instructions for Use for all of the important warnings and precautions before using or prescribing this product.
The United States FDA has authorized use of the gammaCore Sapphire CV device for acute use at home or in a healthcare setting to treat adult patients with known or suspected COVID-19 who are experiencing exacerbation of asthma-related dyspnea and reduced airflow, and for whom approved drug therapies are not tolerated or provide insufficient symptom relief as assessed by their healthcare provider, by using non-invasive vagus nerve stimulation (VNS) on either side of the patient’s neck, available under an emergency access mechanism called an EUA.
gammaCore Sapphire CV has neither been cleared nor approved for acute use at home or in a healthcare setting to treat adult patients with known or suspected COVID-19 who are experiencing exacerbation of asthma-related dyspnea and reduced airflow, and for whom approved drug therapies are not tolerated or provide insufficient symptom relief as assessed by their healthcare provider, by using non-invasive Vagus nerve Stimulation (nVNS) on either side of the patient’s neck during the Coronavirus Disease 2019 (COVID-19) pandemic.
gammaCore Sapphire CV has been authorized for the above emergency use by FDA under an Emergency Use Authorization.
gammaCore Sapphire CV has been authorized only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of medical devices under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked.
