Acute Treatment of Migraine in Adolescents: Real-World Analysis of Remote Electrical Neuromodulation (REN)

Abstract

Nearly 10% of children and adolescents in the United States experience migraine. Pharmacologic treatment of migraine in adolescents is limited due to only few US Food and Drug Administration (FDA)-approved medications, limited efficacy, or lack of tolerability. Remote Electrical Neuromodulation (REN) is a nonpharmacologic abortive treatment for migraine, cleared by the FDA for patients aged 12 years and above. This study evaluated real-world efficacy of REN in adolescents aged 12 to 17 years. Real-world data were collected from patients aged 12 to 17 years treated with the REN device (Nerivio) from January 1, 2021, to May 31, 2022. Study's end points included consistent efficacy two hours after treatment, use of REN as a standalone versus as an adjunct therapy, treatment intensity, and safety. Of 1629 adolescents included in the study, consistent response in at least 50% of treatments at two hours posttreatment was achieved by 60.3% of patients for pain relief, 26.3% for pain freedom, 66.3% for functional disability relief, and 41.2% for functional disability freedom. Of 2365 treatments in which medication usage was reported, REN was used as standalone therapy in 64.4% of the treatments, REN was combined with over-the-counter medications in 18.6%, and it was combined with prescription medications in 17%. Mean treatment intensity from 13,716 treatments was 28.5% (±13.6%) of the max stimulator output. Only three device-related adverse events were reported, all minor. This real-world analysis demonstrates the persistent efficacy of REN for abortive treatment of migraine in adolescents, extending findings of prior clinical trials in adolescents and real-world studies in adults.
