The effectiveness of fingolimod in a Portuguese real world population.
INTRODUCTION Fingolimod is an oral treatment for Relapsing Remitting Multiple Sclerosis (RRMS) with established efficacy in clinical trials. Post marketing studies are important to assess its effectiveness in real world populations. OBJECTIVES To report the effectiveness and safety of fingolimod in a real world population. METHODS A retrospective study of patients with RRMS treated with fingolimod for at least six months. The demographic characteristics, Annualized Relapse Rate (ARR) Expanded Disability Status Score (EDSS) previous treatments and Adverse Events (AE) were analysed. RESULTS 104 patients were included, with a mean treatment duration of 21.06 months. First line disease modifying therapy failure patients (n=56) had an ARR decrease of 68.53% (1.43 vs. 0.45, p<0.001) 66.07% of them were relapse free, EDSS significantly decreased (2.5 vs. 2.0, p<0.001) and 91.07% showed no disability progression. In patients previously treated with natalizumab as a second line drug mainly switched due to safety concerns (n=41) although the differences were not statistically significant, both the ARR and EDSS increased in 41.46% and 19.51% of patients, respectively. In treatment naive patients (n=7) the ARR decreased 94.90% (1.57 vs. 0.08, p=0.027) and there was no disability progression. 56.7% of all patients experienced AE not considered serious in any of the cases. CONCLUSION In this population, fingolimod was an effective treatment after first line treatment failure, decreasing both the ARR and EDSS, and may be an effective option after natalizumab.
