ABSTRACT
BACKGROUND:
Over a dozen disease-modifying therapies (DMTs) have been approved for treatment of multiple sclerosis (MS). Treatment guidelines focus on when to initiate, change, and discontinue treatment but provide little guidance on how to select or sequence DMTs. This study assessed sequencing patterns of DMTs in patients with newly diagnosed MS.METHODS:
Adults newly diagnosed with MS in the United States were identified from January 2007 to October 2017 using IBM MarketScan database. Patients had ≥12 months of continuous enrollment prior to diagnosis and ≥ 2 years of follow-up. Treatment pathways consisting of up to 3 DMT courses were reported, and each treatment course ended with discontinuation, switch, or end of follow-up.RESULTS:
In total, 14,627 MS patients were treated with DMTs and had ≥2 years of follow-up. More than 400 DMT treatment pathways were observed. Glatiramer acetate was the most common DMT; 40% of patients initiated this treatment. Among these, 51.3% had 2 DMT courses during follow-up and 26.5% had 3 DMT courses. Approximately 70% of patients switched or discontinued their initial DMT, and rates of switch and discontinuation differed by initial DMT. Injectable DMTs were used most commonly over the study period (87.5% as first course to 66.6% as third course). Oral DMTs were more common as second or third treatment courses (29.9% and 31.8%, respectively).CONCLUSIONS:
A wide variety in treatment patterns were observed among patients newly diagnosed with MS. Further examination of DMT prescribing practices is needed to understand the reasons behind treatment discontinuation and treatment cycling.Palavras-chave
