Economics of Multiple Sclerosis Disease-Modifying Therapies in the USA

Purpose of Review Multiple sclerosis (MS) is a prevalent and debilitating neuroinflammatory disease associated with a significant economic burden. Direct healthcare costs, which can average $70,000 a year, have risen rapidly over the last decade and are driven by the escalating cost of disease-modifying therapies (DMTs). Despite a growing number of DMTs, annual increases in price for most DMTs have commonly exceeded 10% over the last 15 years. The high cost of MS DMTs has created economic hardships for patients in terms of high out-of-pocket costs and insurance company-induced barriers. Although generic versions of glatiramer acetate and dimethyl fumarate have provided some lower cost options, the median annual price for branded products currently exceeds $90,000. The goal of this paper is to examine the economic landscape of MS DMTs in the USA. Recent Findings Recent economic analyses have provided new insights into the relative value of DMTs. Robust economic modeling studies suggest that costs per quality-adjusted life-year for most DMTs exceed commonly endorsed thresholds for what is considered a reasonable value in the USA. Because of higher efficacy and lower net costs, ocrelizumab and alemtuzumab are considered the best value. It is likely that generic versions of dimethyl fumarate and glatiramer acetate are also economically attractive. Summary DMTs provide clinical benefit for patients with MS; however, their high cost can be a financial burden and impede access. High DMT prices are the principal reason why cost-effectiveness studies have indicated the economic value of most DMTs is questionable.
