Cost Trends of New-To-Market Neurologic Medications: An Insurance Claims Database Analysis.
Article in Neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesCosts for neurologic medications have increased considerably in recent years. Since 2014, more than 30 neurologic medications have been approved by the US Food and Drug Administration (FDA) for neurologic conditions. This study aims to characterize recent trends in annual costs and aggregate spending from 2012 to 2021 for new-to-market (NTM) medications for 9 neurologic conditions.
methodsWe used the Merative MarketScan commercial and Medicare supplemental databases to observe patients seen by a neurologist with neurologic diseases with newly FDA-approved medications from 2014 to 2021: amyotrophic lateral sclerosis (ALS), transthyretin amyloidosis (ATTR), Duchenne muscular dystrophy (DMD), Huntington disease (HD), myasthenia gravis (MG), migraine, orthostatic hypotension (OH), tardive dyskinesia (TD), and spinal muscular atrophy (SMA). Patients were included if they had ≥1 disease-related prescription medication fill from 2012 to 2021. NTM (medications approved from 2014 to 2021) and older evidence-based guideline-supported medications were observed annually. Outcomes examined were annual and aggregate out-of-pocket (OOP) and total medication costs.
resultsWe identified 2,687 unique individuals with ALS, 38 with ATTR, 69 with DMD, 884 with HD, 9,984 with MG, 441,099 with migraine, 4,723 with OH, 1,266 with TD, and 17 with SMA. The youngest population was DMD (mean = 25 years [SD = 7]), and the oldest was TD (mean = 66 years [SD = 14]). For DMD, the population was 99% male and for migraine, the population was 84% female, and the other conditions had more relatively even sex divides. Collectively, migraine medications had the largest increase in aggregate costs (1993%) and had a substantial increase in OOP costs on average by 234% ($86-$288). Eculizumab for MG was an extreme outlier, with OOP costs increasing by 4,099% ($413-$17,359) and aggregate OOP costs by 7,005% ($5,375-$381,894). OOP costs of edaravone ($304-$5,707) and deutetrabenazine ($670-$7,170) sharply increased by 1,775% and 971%, respectively. DISCUSSION: NTM medications for neurologic conditions have substantial and increasing individual and societal costs, which was not observed for older generic medications. These data suggest a need for policies to limit the financial burden of NTM medications on patients with neurologic conditions.
