AUSTIN, TEX – Migraine treatment and prevention is challenging in any population, but some present even more difficulties. Pregnant women and pediatric patients are two such groups where physicians and patients may be hesitant to use drugs.
Neuromodulation devices are proven alternatives to medical interventions, and the remote electrical neuromodulation device Nerivio (Theranica) was cleared by the Food and Drug Administration for acute treatment of migraine patients aged 12 and over in 2021. In March 2023, the agency expanded the clearance to include prevention of migration in adolescents aged 12 and over as well as adults.
Two studies presented at the annual meeting of the American Headache Society showed The latter study yielded similar findings to adults and was used by FDA in its decision to expand the device’s indication in adolescents in 2023, according to Teshamae Monteith, MD, who presented the study at a poster session.
The device, worn on the arm, allows the user to modulate the intensity of the stimulation so that it activates nociceptive pain receptors, but not in a painful way. “Each [patient] raises the intensity until it feels strong, yet comfortable, and when that happens, they activate the nociceptive receptors and the arm sends a signal all the way back up to the brainstem, where the pain control area is. Activating it causes the release of neurotransmitters that inhibit pain. That inhibition is a global pain inhibition mechanism, which causes inhibition of the migraine pain, and also the symptoms associated with migraine like photophobia and vomiting,” said Alit Stark-Inbar, PhD, who presented the study of treatment of pregnant women during a poster session.
Declining treatment days over time in adolescents
Dr. Monteith’s team studied high-frequency remote electrical neuromodulation device use in adolescents who had migraine on 10 days or more per month. They also required at least three treatment days in months 2 and 3 to control for the possibility that patients might stop using the device because they couldn’t afford it or for some reason other than efficacy or because their migraines went away.
The study included 83 adolescents aged 12-17 (mean, 15.9 years, 89% female). In the first month of use, the mean number of migraine treatment days was 12.6, which dropped to 9.0 in month 2 (P < .001), and 7.4 in month 3 (P < .001 from month 2). At 2 hours after treatment, 61.9% had pain relief, 24.5% had freedom from pain, 67.4% had functional disability relief, and 41.3% had functional disability freedom.
“It parallels the findings of the randomized, sham-controlled study in adults. The safety profile was excellent with just one person complaining of minor discomfort of the arm that resolved after treatment. The combination of the exceedingly safe profile and the likelihood of efficacy based on using monthly migraine treatment days as a proxy, the FDA decided to clear this for an adolescent indication,” said Dr. Monteith, associate professor of clinical neurology and chief of the headache division at the University of Miami.
The device design is convenient, according to Dr. Monteith. “The arm is just an easy place to stimulate. It’s a wearable device, and it’s 45 minutes [of treatment] and it’s app controlled. You know adolescents like their technology. They can track their symptoms here, and there’s some biobehavioral power to this because they can do biobehavioral exercises in addition to receiving the simulation,” she said.
The fact that the device is discrete is also an advantage for adolescents in school. “You have to go to the nurse to get your medication versus a device, you can just put it on, it’s easy, no one sees it, and no one’s making fun of you,” said Dr. Monteith.
