Abstract
INTRODUCTION Migraine is a chronic neurological disorder causing severe pain and disability in more than a billion people worldwide. Ideal treatment should provide long-term efficacy with minimal side effects. Previous studies indicate that remote electrical neuromodulation (REN) is an efficacious and safe treatment option for the acute treatment of migraine in clinical practice. This study examined long-term safety, utilization, and efficacy of REN during 12 consecutive usage months. METHODS Data from patients with migraine across the USA using REN to treat their migraine attacks were electronically collected from the Nerivio® device. All patients who used REN during 12 consecutive months were included, and data were compared across months. Safety was assessed by the number and type of adverse events. Utilization was measured by the number of monthly treatments. Efficacy was evaluated as consistent change in headache pain intensity, functional disability, and disappearance of associated symptoms from baseline to 2 h post treatment. RESULTS Data were analyzed from 409 people living with migraine who treated with REN for 12 consecutive months, performing a total of 39,531 treatments. The incidence of device-related adverse events (dAEs) was 1.96% (8/409), including two negligible (0.49%), five mild (1.22%), one moderate (0.24%), and no severe events. All patients continued treatment with REN despite dAEs. One-year average monthly utilization was 8.05 treatments (SD 1.15). Month-to-month utilization did not change during 12 months of consecutive use [F(4.895, 1997.204) = 2.014, p = 0.075, repeated-measures ANOVA]. One-year average efficacy showed 74.1% of users reported consistent 2-h pain relief, and 26.0% reported consistent pain freedom. Month-to-month pain relief and pain freedom did not change during 12 months of consecutive use [F(11, 1069) = 0.55, p = 0.873 and F(11, 1295) = 0.69, p = 0.750 respectively; generalized linear mixed model analysis]. CONCLUSION REN is a safe and well-tolerated acute migraine treatment, with stable efficacy and utilization over 1 year, making it an advantageous non-drug option for the long-term management of this chronic disease. TRIAL REGISTRATION NUMBER NCT05760638.

Remote electrical neuromodulation (REN) wearable device for adolescents with migraine: a real-world study of high-frequency abortive treatment suggests preventive effects. FRONTIERS IN PAIN RESEARCH 2023; 4:1247313. [PMID: 38028429 PMCID: PMC10657883 DOI: 10.3389/fpain.2023.1247313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 10/17/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Migraine is a chronic neurological disease manifesting as attacks of disabling head pain and associated symptoms. Remote electrical neuromodulation (REN) is a non-pharmacological, prescribed, wearable device (Nerivio®). This device has been certified by the FDA for the acute and/or preventive treatment of migraine with or without aura in patients 12 years of age or older. The device is affixed to the user's arm during 45-min treatment sessions and is operated using a smartphone app. This study (NCT05769322) aims to evaluate whether frequent use of REN for the acute treatment of migraine in adolescents resulted in a reduction in monthly migraine treatment days (MMTD), as previously demonstrated in adults through a dedicated prevention clinical trial (NCT04828707). Methods The study included real-world prospective data from adolescent patients who used REN on at least 10 days every 28-day month, following the REN migraine prevention guideline of an every-other-day pattern. Additional requirements were at least three REN treatment days in each of the two subsequent months. The number of MMTD was used as a proxy measure for the number of monthly migraine days (MMD). The change in MMTD from the first month, taken as a "baseline," to each of the following months was used to evaluate the presence and size of potential migraine preventive benefits of REN in adolescents. Results A total of 83 adolescents were eligible for analysis. The users were 15.9 ± 1.3 years of age (mean ± SD), and 89% of them were female. The results demonstrated a substantial month-to-month reduction in the mean (±SD) number of REN treatment days from 12.6 (±3.2) MMTD in the first month to 9.0 (±4.8) MMTD in the second month (p < 0.001), and a further decrease to 7.4 (±4.2) MMTD in the third month (p < 0.001). This indicates an accumulative reduction of 5.2 (±4.8) mean REN MMTD from the first month to the third month of consecutive REN treatment. The users also reported consistent 2-h acute pain responses in at least 50% of their treated attacks, with 61.9% of the users reported experiencing pain relief, 24.5% reported pain freedom, 67.4% indicated relief in functional disability, and 41.3% reported complete freedom from functional disability. Conclusion The frequent use of REN among adolescents as an acute treatment for migraine attacks resulted in a decrease in the mean number of monthly treatment days in the subsequent months, suggesting that REN may have potential preventive benefits for migraine in this subpopulation.

Abstract
PURPOSE OF REVIEW Chronic migraine (CM) affects a large proportion of the population and is a significant source of disability and lost productivity. Numerous non-pharmacological approaches have been attempted during the past decades. This review discusses the most recent and evidence-based advances in acute and preventive non-pharmacological therapeutic approaches for CM, offering alternatives to drug treatment. RECENT FINDINGS A growing number of non-pharmacological treatment options, including non-invasive or invasive neuromodulation, acupuncture, psychotherapy, and physiotherapy, have shown promising efficacy in CM. There is strong evidence for the effectiveness of non-invasive neuromodulation such as transcranial magnetic stimulation, transcranial direct current stimulation, and transcutaneous electrical nerve stimulation (TENS) in CM, but less evidence for approaches such as invasive neuromodulation, physical therapy, or dietary approaches. Acupuncture for migraine remains controversial, with the main point of contention still being the placebo effect. Non-pharmacological approaches can be offered as a reliable alternative for patients with CM, and more research is being done to evaluate the efficacy of non-invasive neuromodulation with different parameters and the combination of different treatments in CM.

Abstract
Digital therapeutics are emerging as a new form of therapeutic interventions. Unlike conventional therapeutics, digital therapeutics deliver interventions directly to patients using an evidence-based, clinically evaluated software to treat, manage, or prevent diseases. Digital therapeutics manifest in diverse forms such as web-based applications, mobile applications on smart devices, virtual reality, and video games. As its own product category for FDA approval, digital therapeutics can function as stand-alone treatments or in combination with conventional therapeutics to improve adherence and/or efficacy. Here, we review the clinical landscape of digital therapeutics. We summarize FDA-approved products and their clinical use, overview >300 ongoing clinical trials, and discuss challenges for their clinical translation and strategies to overcome the same.

Abstract
AIMS Assess the clinical benefits and associated direct and indirect cost-savings from Remote Electrical Neuromodulation (REN) for migraine prevention. METHODS REN, a prescribed, wearable, FDA-cleared neuromodulation-device for the acute and/or treatment of migraine, recently demonstrated efficacy for migraine prevention when used every-other-day, in a prospective, randomized, double-blind, placebo-controlled, multi-center study. Following baseline (4-weeks), subjects underwent treatment with REN (or placebo; 8-weeks), and electronically reported migraine symptoms and acute treatments daily. Therapeutic-gain was the between-groups difference (REN minus placebo) in change from baseline to the second month of intervention. Health-economics impact was derived as cost-savings associated with REN's clinical benefits. RESULTS Out of 248 subjects randomized (128 active, 120 placebo), 179 (95:84) qualified for modifiedintention-to-treat (mITT) analysis. Significant therapeutic gains favoring REN vs placebo were found (Tepper et al., 2023), including mean (±SD) reduction in number of acute medication days (3.4 ± 0.4 vs 1.2 ± 0.5; gain = 2.2; p = 0.001) and presenteeism days (2.7 ± 0.3 vs 1.1 ± 0.4; p = 0.001). Mean changes of provider visits (reduction of 0.09 ± 0.1 vs increase of 0.08 ± 0.2; p = 0.297), and reduction of absenteeism days (0.07 ± 0.1 vs 0.07 ± 0.2; p = 0.997) were not significant. Mean annual cost-saving for one patient using REN for migraine prevention estimated $10,000 (±$1,777) from reductions in these four clinical outcomes relative to baseline without REN treatment. Extrapolated to a hypothetical US commercial health-plan of one-million covered lives, assuming the national prevalence of migraine patients on preventive treatment, annual mean (±SE) cost-saving from using REN migraine prevention estimated $560.0 million (±$99.5 million) from reduction in direct and indirect metrics measured. LIMITATIONS Clinical and cost-savings benefits presented are conservative, assessed only from endpoints measured in the clinical trial. Moreover, some of the endpoints had only scarce or no occurrences during the study period. CONCLUSIONS Demonstrated significant and meaningful clinical, and cost-savings benefits for patients, health insurance systems, and employers, from utilizing REN for migraine prevention.

Abstract
As a new therapeutic technique based on digital technology, the commercialization and clinical application of digital therapeutics (DTx) are increasing, and the demand for expansion to new clinical fields is remarkably high. However, the use of DTx as a general medical component is still ambiguous, and this ambiguity may be owing to a lack of consensus on a definition, in addition to insufficiencies in research and development, clinical trials, standardization of regulatory frameworks, and technological maturity. In this study, we conduct an in-depth investigation and analysis of definitions, clinical trials, commercial products, and the regulatory status related to DTx using published literature, ClinicalTrials.gov, and web pages of regulatory and private organizations in several countries. Subsequently, we suggest the necessity and considerations for international agreements on the definition and characteristics of DTx, focusing on the commercialization characteristics. In addition, we discuss the status and considerations of clinical research, key technology factors, and the direction of regulatory developments. In conclusion, for the successful settlement of DTx, real-world evidence-based validation should be strengthened by establishing a cooperative system between researchers, manufacturers, and governments, and there should be effective technologies and regulatory systems for overcoming engagement barriers of DTx.

Abstract
OBJECTIVE To assess the clinical efficacy of remote electrical neuromodulation (REN), used every other day, for the prevention of migraine. BACKGROUND Preventive treatment is key to managing migraine, but it is often underutilized. REN, a non-pharmacological acute treatment for migraine, was evaluated as a method of migraine prevention in patients with episodic and chronic migraine. METHODS We conducted a prospective, randomized, double-blind, placebo-controlled, multi-center trial, with 1:1 ratio. The study consisted of a 4-week baseline observation phase, and an 8-week double-blind intervention phase in which participants used either REN or a placebo stimulation every other day. Throughout the study, participants reported their symptoms daily, via an electronic diary. RESULTS Two hundred forty-eight participants were randomized (128 active, 120 placebo), of which 179 qualified for the modified intention-to-treat (mITT) analysis (95 active; 84 placebo). REN was superior to placebo in the primary endpoint, change in mean number of migraine days per month from baseline, with mean reduction of 4.0 ± SD of 4.0 days (1.3 ± 4.0 in placebo, therapeutic gain = 2.7 [confidence interval -3.9 to -1.5], p < 0.001). The significance was maintained when analyzing the episodic (-3.2 ± 3.4 vs. -1.0 ± 3.6, p = 0.003) and chronic (-4.7 ± 4.4 vs. -1.6 ± 4.4, p = 0.001) migraine subgroups separately. REN was also superior to placebo in reduction of moderate/severe headache days (3.8 ± 3.9 vs. 2.2 ± 3.6, p = 0.005), reduction of headache days of all severities (4.5 ± 4.1 vs. 1.8 ± 4.6, p < 0.001), percentage of patients achieving 50% reduction in moderate/severe headache days (51.6% [49/95] vs. 35.7% [30/84], p = 0.033), and reduction in days of acute medication intake (3.5 ± 4.1 vs. 1.4 ± 4.3, p = 0.001). Similar results were obtained in the ITT analysis. No serious device-related adverse events were reported in any group. CONCLUSION Applied every other day, REN is effective and safe for the prevention of migraine.

Abstract
Migraine is a chronic and often lifelong disease that directly affects over one billion people globally. Because access to migraine medical services is limited, only a minority of migraine patients are treated adequately. This situation worsened during the COVID-19 pandemic. Digital therapeutics (DTx) is an emerging therapeutic approach that opens up many new possibilities for remote migraine management. For instance, migraine management tools, online migraine diagnosis, guideline-based treatment options, digitally networked patients, and collecting anonymized information about migraine attacks and course parameters for scientific evaluation. Various applications of DTx in migraine management have been studied in recent years, such as the usefulness of digital migraine self-management tools in diagnosing and tracking migraine attacks, and the efficacy and safety of digital cognitive behavioural therapy. However, the development of DTx is still in its infancy and still faces many obstacles. The primary goal of this study is to review the latest research on DTx in migraine management, identify challenges, and outline future trends.

Abstract
Aim. Neuropathic pain affects 7–10% of the population, with most of the patients receiving inadequate and incomplete treatment. Owing to the high financial burden and the poor quality of life of the patients and their caretakers, there is a dire need to address the challenges in diagnosing and treating chronic neuropathic pain. Methods. This literature review was conducted to review novel treatments and related challenges through a systematic search from sources such as PubMed, Google Scholar with the combination of MESH words such as neuropathic pain, management of neuropathic pain. Articles from non-English literature, reports without human subjects, animal studies, and abstracts/posters were excluded. However, human studies and studies published in English were included. Result. This review article discusses novel treatment modalities while acknowledging the challenges medical workers face while encountering neuropathic pain. Despite the recent advances in diagnosis and treatment modalities, several challenges still exist. Hence, there is still a need to explore the various treatment modalities, emphasizing the cause and underlying pathophysiology of neuropathic pain. Conclusion. We recommend integrated multimodal treatment with the current treatment facility, including various medical disciplines. However, a personalized approach would work the best depending on the ’patient’s medical history. Therefore, this article recommends an integrated, cause-specific, cost-effective approach to address this problem of chronic neuropathic pain.
