Efficacy of fingolimod is superior to injectable disease modifying therapies in second-line therapy of relapsing remitting multiple sclerosis

Abstract

Although fingolimod is registered in Europe for treatment of relapsing-remitting multiple sclerosis (RRMS) if earlier disease modifying therapy (DMT) has failed, no data regarding its efficacy in this patient group are available. This observational cohort study of the NeuroTransData network includes German RRMS outpatients with failure of earlier therapy with injectable DMT (iDMT), therefore switching to either another iDMT (n = 133) or to fingolimod (n = 300). Statistical comparison of clinical baseline characteristics showed more severely affected patients in the fingolimod group. A propensity-score matched group comparison was performed (n = 99 in each group) covering more than 2-year observation time. Fingolimod showed statistically significant superior efficacy in comparison to iDMT regarding annualized relapse rate (0.21 versus 0.33 per year), time-to-relapse and likelihood of relapse (iDMT hazard ratio 1.7), proportion and likelihood of patients with EDSS progression (15.10 versus 31.00 %; iDMT hazard ratio 1.7), persistence on medication and likelihood of discontinuation (iDMT hazard ratio 3.0). Significantly more patients were free of relapse and EDSS progression with fingolimod than with their second iDMT (64.4 versus 46.5 %, p < 0.03). This real-life evidence in German RRMS outpatients support data from controlled clinical studies and can quantitatively support clinical decision finding processes if iDMT therapy fails in RRMS.
