BASKING RIDGE, N.J., Nov. 28, 2018 (GLOBE NEWSWIRE) -- electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced that it received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for an expanded label for gammaCore™ [non-invasive vagus nerve stimulator (nVNS)] therapy for adjunctive use for the preventive treatment of cluster headache in adult patients. This milestone marks the first and only product FDA cleared for the prevention of cluster headache. There are currently no FDA-approved pharmacologic treatments for the prevention of cluster headache.

“The FDA clearance of gammaCore for adjunctive use for the preventive treatment of cluster headache has the potential to help the approximately 350,000 Americans impacted by this debilitating condition often referred to as a ‘suicide headache,’” said Frank Amato, Chief Executive Officer at electroCore. “We are pleased that cluster headache patients now have a FDA-cleared option, and one that is both safe and effective, especially given the difficulty in treating cluster headache and the limitations of current treatments.”

This clearance was supported by results from two studies, including from the PREVA (PREVention and Acute treatment of chronic cluster headache) pivotal study, a prospective, open-label, controlled, randomized clinical trial that demonstrated the safety and effectiveness of gammaCore as an adjunctive therapy for the preventive treatment of cluster headache. The second study reviewed by the FDA was a real world retrospective study examining the daily clinical use of gammaCore preventively and acutely for the treatment of cluster headache.

In the PREVA study, intention-to-treat (ITT) patients who received the standard of care and gammaCore (SoC plus nVNS, n=45; control, n=48) during the randomized phase had a greater reduction from the baseline (−5.9) in the number of cluster attacks per week than those receiving standard of care (−2.1), for a mean therapeutic gain of 3.9 fewer cluster attacks per week (P=0.02). In the site-adjusted model, the mean therapeutic gain was 4.2 fewer attacks per week (P=0.02).

Furthermore, 40 percent of patients who received gammaCore in addition to standard of care experienced a 50 percent or greater reduction in weekly cluster attacks, compared to 8.3 percent of patients who received standard of care alone (P<0.001).

In addition, there was a 57 percent decrease in the frequency of abortive medication use among patients who received gammaCore plus standard of care (P<0.001), while patients who received standard of care alone did not experience a substantial reduction in abortive medication use (P=0.59).  

In this study, gammaCore was found to be safe and well tolerated. The incidence of adverse events was similar between patients using gammaCore plus standard of care compared to standard of care alone. The majority of the adverse events were mild and transient. The most common adverse events reported in five percent of patients or more in the gammaCore group were headache (8%), dizziness (6%) and neck pain (6%). None of the serious adverse events were considered device-related.

To prevent cluster headache, adult patients should self-administer two gammaCore treatments daily. Each treatment consists of three consecutive 2-minute stimulations. The first treatment should be applied within one hour of waking up and the second treatment should be applied at least 7-10 hours later.

gammaCore is available by prescription only and patients should speak with their doctor about whether gammaCore is right for them.

About gammaCore
gammaCore™ (nVNS) is the first non-invasive, hand-held medical therapy applied at the neck as an adjunctive therapy to prevent cluster headache and acutely treats the pain associated with episodic cluster headache and migraine in adult patients 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 cleared in the U.S. as an adjunctive treatment to prevent cluster headache and for the acute treatment of pain associated with episodic cluster headache and migraine headache in adult patients. gammaCore is the only FDA-cleared product for the prevention of cluster headache.

IMPORTANT SAFETY INFORMATION REGARDING GAMMACORE

  • The safety and effectiveness of the gammaCore (nVNS) have not been established in the acute treatment of chronic cluster headache.
  • gammaCore has not been shown to be effective for the preventive treatment of migraine headache.
  • The long-term effects of the chronic use of gammaCore have not been evaluated. 
  • Safety and efficacy of gammaCore have not been evaluated in the following patients, and therefore is NOT indicated for: 
    • Patients with an active implantable medical device, such as a pacemaker, hearing aid implant, or any implanted electronic device
    • 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 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) 

Note: This list is not all inclusive. Please refer to the gammaCore Instructions for Use for all important warnings and precautions before using or prescribing this product. 

gammaCore is available by prescription only. U.S. Federal Law restricts this device to sale by or on the order of a licensed healthcare provider. 

About Cluster Headache
Cluster headache is a series of relatively short but extremely painful headaches that has been described by patients and physicians as one of the most painful conditions in medicine. The suicide rate among these patients is 20 times the U.S. national average, leading to the condition being referred to as the “suicide headache.” There are approximately 350,000 cluster headache sufferers in the United States, approximately 225,000 of whom seek treatment each year primarily from the same headache specialists who treat migraine.
