RESUMEN

Aim: To evaluate the onset, magnitude and persistence of efficacy of remote electrical neuromodulation (REN) compared with placebo for the preventive treatment of migraine. Materials & methods: Analysis was conducted on data from a prospective, double-blind, placebo-controlled clinical trial, which assessed the efficacy of REN for the prevention of migraine. The number of monthly migraine days (MMD) per group was calculated in 2-week intervals and compared between the groups. Results: Differences between the active (N = 95) and placebo (N = 84) groups reached significance at 2 weeks: therapeutic gain 0.84 MMD; p = 0.036. 4 weeks gain 1.59 MMD; p = 0.025, 6 weeks gain 2.27 MMD; p < 0.001, 8 weeks gain 2.68 MMD; p < 0.001. Conclusion: REN provides rapid and consistent efficacy in preventive treatment of migraine.

RESUMEN

INTRODUCTION: Migraine is one of the most prevalent neurological disorders worldwide, and estimations are that 60% of women who suffer from migraines experience attacks that are associated with menstruation. Menstrual migraines are typically more debilitating and less responsive to pharmacological treatment. Remote electrical neuromodulation (REN) is a non-pharmacological abortive treatment of migraine headache. The current study evaluated the self-reported effectiveness and tolerability of REN for the acute treatment of menstrual migraine, via a retrospective structured survey that was sent to adult female REN users. METHODS: Women aged 18-55 years who experience menstrually related or pure menstrual migraine and have completed at least four REN treatments, participated in this retrospective, observational survey study. Participants completed a short online survey assessing effectiveness, satisfaction, and safety outcomes. RESULTS: Ninety-one participants qualified for the analysis, out of which 74.7% (68/91) reported that the treatment was at least moderately effective (moderately effective 37.4%, very effective 26.4%, extremely effective 11.0%). Additionally, 45.1% (41/91) reported satisfaction from REN (slightly satisfied 33%, extremely satisfied 12.1%), while 34.1% were neutral and 20.9% (19/91) were not satisfied. Lastly, 100% of the participants reported that the treatment is at least moderately tolerable (moderately tolerable 8.8%, very tolerable 20.9%, extremely tolerable 70.3%), and 13.2% (12/91) of respondents reported mild short-term side effects. CONCLUSIONS: Nearly 75% reported that the treatment was at least moderately effective, 45% reported satisfaction, and 100% of the participants reported that the treatment is at least moderately tolerable. Thirteen percent reported mild short-term side effects. REN was thus reported as effective for menstrual migraine by most participants and was very well tolerated. Therefore, REN may provide a safe, non-pharmacological alternative for the acute treatment of menstrual migraine. CLINICALTRIAL. GOV REGISTRATION NUMBER: NCT04600388.

RESUMEN

Introduction: Migraine is a chronic neurological disease that is the primary cause of years lived with disability in people under the age of 50. Remote electrical neuromodulation (REN) is a novel drug-free acute treatment of migraine, that is FDA cleared for episodic and chronic migraine. As a prescribed digital therapeutic, REN enables large-scale post-marketing research, thus providing real-world information on the use of the intervention in a wide range of populations, environments, and situations. Methods: The REN device (®Nerivio) includes a secured, personal migraine diary, which patients can use to record their symptoms before treatment and 2 h post-treatment. Real-world data on REN treatments were collected via the app from patients across the United States who used Nerivio between October 1st, 2019, and May 24th, 2021. Data analysis focused on four metrics: 1. Per-treatment patterns of REN use as a standalone treatment vs. in combination with medications. 2. Per-user intra-individual efficacy across multiple treatments. 3. Distribution of treatment intensity among users (the electroceutical equivalent to treatment dose). 4. Prevalence and severity of adverse events. Results: 1. Out of 23,151 treatments, in 66.5% of treatments REN was used as a standalone treatment, in 12.9% it was followed by over-the-counter medications, and in 20.6% followed by prescription medications. 2. Out of 2,514 patients, response in at least 50% of treatments was achieved in 66.5% of cases for pain relief, and in 22.6% for pain freedom. 3. Out of 117,583 treatments, in 80% of cases intensity levels were between 18 and 55% of the stimulator's range. The mean intensity was 34.3% of the stimulator's output (±16.6%). 4. Out of 12,368 users (121,947 treatments), there were 59 users (0.48%) who reported device related adverse events, 56 (0.45%) of which were mild, three (0.03%) were moderate, and none were severe. Conclusions: The current analysis of real-world clinical data indicates that REN provides an efficacious, stable, and safe treatment option for acute treatment of migraine in real-world settings, both as a standalone replacement of pharmaceuticals, as well as an adjunct to medications.
