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 acute and/or preventive 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 modified intention-to-treat (mITT) analysis. Significant therapeutic gains favoring REN vs. placebo were found (Tepper etal. 2023), including mean (±SD) reduction in number of acute medication days (3.5±0.4 vs. 1.2±0.5; gain = 2.2; p=.001) and presenteeism days (2.7±0.3 vs. 1.1±0.4; gain = 1.6, p=.001). Mean changes of provider visits (reduction of 0.09±0.1 vs. increase of 0.08±0.2; p=.297), and reduction of absenteeism days (0.07±0.1 vs. 0.07±0.2; p=.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 ($330 millionm) and indirect costs ($230 millionm) 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: Coverage of the REN-device for migraine prevention may significantly reduce disease-burden and save a one-million-member payer plan at least $560 million per year.
