electroCore, Inc. Announces Study of gammaCore Sapphire(TM) for the Treatment of Post-COVID Syndrome

ROCKAWAY, N.J., July 07, 2022 (GLOBE NEWSWIRE) — electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced Mayo Clinic is initiating an investigator-initiated study to assess the efficacy of gammaCore Sapphire non-invasive vagus nerve stimulation (nVNS) in patients with post-COVID syndrome. Post-COVID syndrome, also known as Long COVID, is a collection of symptoms that persist greater than 28 days after the initial onset of symptoms of SARS-CoV-2 (COVID) infection




. These symptoms, such as headache, brain fog, fatigue and gastric distress can bear a striking resemblance to the “central sensitization syndromes,” a group that includes fibromyalgia, chronic fatigue syndrome, and postural orthostatic tachycardia syndrome (POTS). Post-COVID syndrome is likely to occur in upwards of 10% of the population who has been infected with COVID, likely affecting hundreds of millions across the world.

The study entitled “Outcomes of treatment with non-invasive vagal nerve stimulation (nVNS) in post-COVID syndrome: A Pilot Study,” is a randomized, single-center, controlled trial enrolling up to 20 subjects recruited from the Post-COVID Care Clinic at Mayo Clinic in Rochester, Minnesota. Endpoints of the study include a number of clinical questionnaires including the Post-COVID Functional Status Score, as well as an analysis of blood samples for certain chemokines, and positron emission tomography-computed tomography (PET-CT) of the brain to evaluate brain metabolism.

“Long-COVID represents a significant ongoing medical challenge that can extend long after the acute phase of COVID,” said Dr. Peter Staats, Chief Medical Officer at electroCore, Inc. “We believe the decision to use gammaCore Sapphire is consistent with its demonstrated mechanisms of action and its use in acute-COVID under an Emergency Use Authorization granted by the Food and Drug Administration.”

About gammaCore™

gammaCore™ (nVNS) is the first non-invasive, hand-held medical therapy applied at the neck 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 is 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
