Abstract

Background: clinical factors and frequency of disease-modifying therapy (DMT) changes/interruptions in relapsing-remitting multiple sclerosis (RRMS) patients have not been well defined. The aim of this study was to describe reasons of MS treatment modifications in a large cohort of Italian MS patients.Methods: this multicenter, cross-sectional non interventional study (SWITCH) conducted at 28 Italian MS centers, screened, by visit/telephone contact between June 2016 and June 2017, all RRMS patients receiving stable DMT treatment and enrolled patients with change in DMT treatment.Results: out of 13,657 recorded in the log, 409 (3%) changed therapy. Of these, 336 (2.5%), met the study criteria and were considered eligible. Among 303 (90.2% of 336) patients switching, the most common reason was "lack of efficacy" (58.4% of 303). Among 30 (8.9%) patients who interrupted treatment temporarily, the most common reason was pregnancy (40.0% of 30). Out of 3 (0.9%) patients who discontinued treatment permanently, 2 (66.7%) had as first reason as "patient decision". Multivariate analysis showed that EDSS was the only variable with statistically significant effect on changing treatments (r = 8.33; p-value of Type III Sum of Squares = 0.016).Conclusion: in our study, 303 (90.2% of eligible patients) switched treatment, 30 (8.9%) interrupted treatment temporarily, and 3 (0.9%) discontinued treatment permanently. Efficacy remains the main driving force behind switching behavior, as the primary aim of treatment is to be disease free or reduce disease activity.
