gammaCore (Non-Invasive Vagus Nerve Stimulation; nVNS) Reduces Symptoms of Acute Withdrawal in Patients with Opioid Use Disorder – Yahoo Finance

ROCKAWAY, N.J., Sept. 07, 2022 (GLOBE NEWSWIRE) —  electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced the publication of a peer reviewed manuscript, Transcutaneous Cervical Vagus Nerve Stimulation Reduces Behavioral and Physiological Manifestations of Withdrawal in Patients with Opioid Use Disorder: A Double-Blind, Randomized, Sham-Controlled Pilot Study in the journal, Brain Stimulation. The study, conducted with the support of Emory and Georgia Tech University, was sponsored by a grant from the National Institute on Drug Addiction (NIDA), part of the National Institutes of Health (NIH), through NIH Helping to End Addiction Long-term® Initiative, or NIH HEAL Initiative.
Substance use is an escalating crisis in the United States, with opioid-related drug overdose deaths rising above 100,000 in 2021.1 The standard of care for treating opioid use disorder (OUD) is medication for opioid use disorder (MOUD), including opioid receptor agonists and antagonists. Yet, the barriers to care are high with only 11% of patients who have OUD receiving the MOUD they need.2 Additionally, OUD relapse is common amongst patients. As many as 70% of patients with OUD return to use without medication and 46% of patients on methadone, an opioid agonist medication, will relapse.3 Treatment with the opioid antagonist naltrexone requires an extended period of detoxification before initiation, which can be associated with withdrawal symptoms. Relapse during this period may be associated with an even higher risk of relapse-related overdose and death.4,5 New treatments are therefore necessary for managing withdrawal in the treatment of OUD.
This double-blind, randomized, sham-controlled study of 21 patients with OUD found that nVNS reduced both the psychological and physiological symptoms of acute opioid withdrawal. In particular, statistically significant reductions in opioid withdrawal symptoms (-1.9 ± 3.7 vs. 0.4 ± 1.0; p=0.047), distress (-17.5 ± 26.5 vs. 2.2 ± 5.9; p=0.004), and pain (-0.8 ± 2.4 vs. 0.9 ± 1.0; p=0.045) were observed over the course of a 2-hour protocol for the nVNS group, in comparison to the sham stimulation group. This was accompanied by a statistically significant decrease in heart rate during active nVNS compared to sham stimulation, across all stimulations (-5.5 ± 3.5 bpm vs. -1.4 ± 2.3 bpm; 0=0.035).
Dr. Douglas Bremner, Professor of Psychiatry and Radiology at Emory University School of Medicine and the primary investigator for the study commented, “Opioid Use Disorder is a crisis across the United States. Current treatments do not provide adequate options to help patients initiate and maintain opioid withdrawal programs.” Dr. Omer Inan, the Linda J. and Mark C. Smith Chair in Bioscience and Bioengineering, Associate Professor of Electrical and Computer Engineering at Georgia Institute of Technology, and co-investigator on the study added, “As a non-invasive, nonpharmacological therapy that poses minimal risk and is amenable to self-administration, nVNS represents a potentially valuable treatment for OUD.”
“We congratulate and thank Dr. Bremner, Dr. Inan, and their clinical and research teams at Emory University and Georgia Tech University, as well as the team at NIDA for their support of this study,” commented Eric Liebler, Senior Vice President of Neurology at electroCore. “Opioid addiction strikes individuals, families and society, and we look forward to continuing to partner with NIDA to confirm the potential of gammaCore (nVNS) as a treatment for OUD.”

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
