Put the power of non-drug relief in your patients' hands

Consider gammaCore: a non-drug treatment for migraine headache

Migraine pain not only impacts a patient’s body, it impacts their life. Choosing gammaCore (nVNS) will provide your patients with a unique treatment that is proven safe and delivers fast relief, reliable relief, and reduction in headache duration.1-3

Clinically proven as an effective treatment for migraine pain1,2

A double-blind, randomized, sham-controlled trial evaluated the safety, efficacy, and tolerability of gammaCore in 243 patients with migraine headache

Study Design

Primary endpoint: Pain-free at 120 minutes; first attack.
Study population: Patients aged 18-75 years, who had been diagnosed with migraine and experienced 3-8 migraine attacks per month and less than 15 headache days a month, were included.


Fast relief from the first treated migraine1-3

gammaCore provided significant relief in as soon as 30 minutes

Percentage of Patients Who Were Pain-Free for the First Migraine

gammaCore provided improved relief vs sham at 30, 60, and 120 minutes
75% of patients who were pain-free at 2 hours were also pain-free at 24 hours
While more patients experienced relief with gammaCore at 120 minutes (primary endpoint), it was not statistically significant


Reliable relief across multiple migraines1,3

gammaCore provided reliable relief for more patients vs sham

Migraine Patients Successfully Treated ≥50% of Migraines

*Patients with mild pain at both baseline and 120 minutes were not considered responders.

Almost half of the patients treated with gammaCore reported mild or no pain at 120 minutes for more than 50% of all treated headaches


Reduction in pain intensity for first migraine1-3

gammaCore significantly decreased pain intensity vs sham

Reduction of Pain Intensity of First Treated Migraine

†Post-hoc analysis.

gammaCore reduced pain intensity over 3x greater than sham at 60 minutes and over 6x greater at 120 minutes
gammaCore reduced the need for other rescue medications


Consider gammaCore: a promising treatment for episodic cluster headache

Episodic cluster headache is a debilitating condition that’s hard to treat. Those who suffer from episodic cluster headache have periods of time when they have multiple attacks per day. The pain quickly becomes extremely severe or unbearable and can last from 15 to 180 minutes.

Despite the current treatments available for cluster headache pain, many patients are dissatisfied with the current options and are looking for new, effective treatments.

gammaCore (nVNS) is proven safe and effective for episodic cluster headache pain and can provide patients with fast relief, reliable relief, and reduction in duration and intensity of attacks.

One of the largest clinical programs conducted for cluster headache pain4

Two randomized, double-blind, sham-controlled clinical studies included patients with episodic cluster headache (eCH) and chronic cluster headache (cCH). Pain intensity was scored on a 0-4 scale, with 0 being “no pain” and 4 being “very severe pain”.1,4,5

In ACT1 Study, the primary endpoint was the percentage of people who reported “mild pain” or “no pain” 15 minutes after using gammaCore to treat their first attack.1,4

In ACT2 Study, the primary endpoint was the percentage of total attacks that were pain-free 15 minutes after using gammaCore, with no use of rescue medication throughout the treatment period (30 minutes), and had the option to repeat treatment approximately 3 minutes after the first treatment.1,5

Fast relief from the first attack1,4,5

gammaCore provided better relief at 15 minutes vs sham

Response in First Treated Attack (Primary Endpoint): All Study Groups1,4

  • Significantly more episodic cluster headache patients responded with gammaCore for the first treated cluster attack vs those receiving sham (response = reporting “mild pain” or “no pain” at 15 minutes)

Percentage of All Attacks That Were Pain-Free at 15 Minutes (Primary Endpoint): All Study Groups1,5

  • Among episodic cluster headache patients, significantly more episodic cluster attacks treated with gammaCore were pain-free at 15 minutes vs those treated with sham

Reliable relief for at least half of treated attacks1,4,5

gammaCore provided reliable relief for more patients vs sham

Episodic Cluster Headache Patients Successfully Treated ≥50% of Attacks1,4*

*Response defined as "no pain" or "mild pain" at 15 minutes.

  • Significantly more episodic cluster headache patients responded to gammaCore at 15 minutes for ≥50% of all treated attacks vs those receiving sham

Episodic Cluster Headache Patients Successfully Treated ≥50% of Attacks1,5‡

‡Response defined as “no pain” or “mild pain” at 15 minutes.

  • Significantly more episodic cluster headache patients treated with gammaCore responded within 15 minutes in ≥50% of treated attacks vs those treated with sham

Reduction in the duration and intensity of attacks1,4,5

gammaCore decreased the length and the severity of attacks vs sham

Significant Reduction in Duration of First Treated Attack in Episodic Cluster Headache Patients1,4*

*Based on available patient data.

  • Episodic cluster headache patients treated with gammaCore also had a significantly greater mean reduction in the duration of the treated attacks vs those treated with sham, who had an increase in attack duration

Significant Reduction in Pain Intensity Across All Treated Attacks in Episodic Cluster Headache Patients1,5‡

‡ Mean of all attacks per patient.

  • Episodic cluster headache patients treated with gammaCore also reported significantly greater reduction in pain intensity at 15 minutes vs those treated with sham

NOTE: While the clinical studies included patients with chronic cluster headache, gammaCore is indicated for the acute treatment of pain associated with episodic cluster headache in adult patients.
