Real-world patient characteristics, treatment patterns and costs in relapsing multiple sclerosis patients treated with glatiramer acetate, dimethyl fumarate or teriflunomide in Germany.

Drugs used for relapsing multiple sclerosis (RMS) include, among others, glatiramer acetate (injection), dimethyl fumarate (tablet) and teriflunomide (tablet). We compared treatment adherence (based on drug claims), healthcare use and costs for these drugs. Treatment adherence and healthcare use was similar for these three drugs. The need to be in hospital was lower with these drugs compared with not using them. No differences in treatment costs were seen between these drugs. Adherence reduced the need for hospital stays and lowered some costs compared with patients who were classified as adherent. RMS patients should be encouraged to take their RMS medication as prescribed. Improving treatment adherence will have a positive effect on RMS, and a good impact on healthcare use and costs.
