Abstract

Aim: In Poland, the availability of therapies in relapsing-remitting multiple sclerosis (RRMS) is regulated by the National Health Fund (NFZ, Narodowy Fundusz Zdrowia) regulations, according to which the second-line therapy is now possible only with two medications (natalizumab, fingolimod) and only in patients, who suffered relapses and developed new lesions observed in MRI during first-line treatment in the period of minimum 12 months. The aim of this study is to evaluate the effects of second-line treatment with fingolimod by means of the analysis of the impact of the therapy on the frequency of relapses, the degree of disability progression and the occurrence of side effects.


Methods: Analysis covered 30 RRMS patients switched from first-line therapy to fingolimod. The annualized relapse rate, disability progression (assessed with Expanded Disability Status Scale, EDSS) and MRI results (new or enlarged T2 lesions and new Gd-positive lesions) before and after switching were compared. The occurrence of adverse events was also assessed.


Results: The annualized relapse rate for fingolimod therapy was significantly lower than for first-line therapy (0.26 ± 0.65 vs. 2.08 ± 0.87; p = 0.00005). The mean number of new or enlarged T2 and Gd+ lesions in MRI after one-year fingolimod treatment was significantly lower in comparison to MRI performed at the end of the first-line therapy (for T2: 0.6 vs 4.23; p = 0.0004, for Gd+: 0.2 vs. 1.83; p = 0.0009). Median of EDSS progression with first-line therapy was significantly higher than that with fingolimod treatment (p = 0.00002).


Conclusions: Treatment with fingolimod as a second-line therapy in RRMS patients is safe and effective. Less restrictive criteria for switching should be considered.
