electroCore Announces Open Access and Submission of Manuscript from SAVIOR-1

Study evaluated impact of non-invasive vagus nerve stimulation in hospitalized COVID-19 patients

ROCKAWAY, NJ, Sept. 29, 2021 (GLOBE NEWSWIRE) — electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced that the original author manuscript from the SAVIOR-1 study; a prospective, randomized, controlled study evaluating non-invasive vagus nerve stimulation (nVNS) using gammaCore SapphireTM in patients admitted to the hospital for treatment of COVID-19; is available on MedRxiv and has been submitted for peer review. This study was an investigator-initiated trial conducted at the Hospital Clínico Universitario de Valencia, Spain.

The SAVIOR-1 study enrolled 110 patients over 18 years of age between April 2020 and February 2021. A total of 97 patients comprised of 47 treatment subjects and 50 control subjects provided baseline demographic and medical history data. The study was designed to evaluate the safety and feasibility of nVNS when administered in addition to the then-standard of care in patients hospitalized with active SARS-CoV-2 infection compared with standard of care alone.

The analyses identified significant treatment differences for certain biomarkers of inflammation. Decreases from baseline in C-reaction protein (CRP) levels were significantly greater for the nVNS treatment group as compared to the control group throughout the five-day period combined (p= 0.010) and on day 5 compared to the day 1 baseline period alone (p= 0.012). At day 1, CRP levels were highly elevated for 90% of all subjects, but by days 3 and 5, the percentage of subjects with normal CRP levels improved markedly in the nVNS group with day 3 CRP levels at 17.9% vs. 52.2% in the control (p=0.010). Additionally, the nVNS group had a significantly greater decrease from baseline in procalcitonin level at day 5 (p=0.004) as compared to the control group. Increased levels of CRP, procalcitonin and d-dimer have all been reported to be associated with more severe disease and the lower levels of these markers in the nVNS treated group may represent the initial impact of nVNS therapy to potentially improve the course of a patients’ COVID-19 symptoms.

nVNS was well tolerated with no major device related adverse events and the therapy was administered three times daily on most patients as outlined in the study protocol.

The principal investigator of the study, Dr. Carlos Tornero, Head of the Department of Anesthesiology, Resuscitation and Pain Therapeutics of the Hospital Clínico Universitario de Valencia, Spain, commented, “Our results suggest that nVNS may contribute to our efforts in combating the ongoing COVID-19 disease process and its long-term effects through the modulation of biomarkers that are typically associated with a more severe prognosis.”

“The ability of nVNS to potentially affect the progression of COVID-19 in these hospitalized patients is encouraging.” said Dr. Peter Staats, Chief Medical Officer of electroCore. “As the pandemic continues to evolve, we believe that nVNS could be an appropriate treatment for patients suffering from the long-term effects of COVID-19 by helping combat the increased levels of inflammation.”

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, the treatment of paroxysmal hemicrania and hemicrania continua in adults, and the acute and preventive treatment of migraine in adolescent (ages 12 and older) and 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

The U.S. FDA has cleared the gammaCore Sapphire CV device under an emergency use authorization for acute use at home or in a healthcare setting to treat adult patients with known or suspected COVID-19 who are experiencing an exacerbation of asthma-related dyspnea and reduced airflow, and for whom approved pharmacologic therapies are not tolerated or provide insufficient symptom relief as assessed by their healthcare provider, using noninvasive vagus nerve stimulation (nVNS) on either side of the patient’s neck.

gammaCore Sapphire CV has been authorized only for the duration of the statement that circumstances exist that warrant authorization of the emergency use of medical devices under section 564(b)(1) of the Act, 21 U.S.C. § 360bbbb-3(b)(1), until the authorization is terminated or revoked.
