Treatment Patterns by Race and Ethnicity in Newly Diagnosed Persons with Multiple Sclerosis.

Background: Non-Hispanic Black and Hispanic persons with MS (pwMS) are more likely to experience rapid disease progression and severe disability than non-Hispanic White pwMS; however, it is unknown how the initiation of high-efficacy disease-modifying therapies (DMTs) differs by race/ethnicity. This real-world study describes DMT treatment patterns in newly diagnosed pwMS in the United States (US) overall and by race/ethnicity.

Methods: This retrospective analysis used the US Optum Market Clarity claims/electronic health records database (January 2015-September 2020).
