Background
The introduction of oral disease-modifying therapies (DMTs) for relapsing–remitting multiple sclerosis (RRMS) changed algorithms of RRMS treatment.
Objectives
To compare the effectiveness of treatment with dimethyl fumarate (DMF) and teriflunomide (TRF) in a large multicentre Italian cohort of RRMS patients.
Materials and Methods
Patients with RRMS who received treatment with DMF and TRF between January 1st, 2012 and December 31st, 2018 from twelve MS centers were identified. The events investigated were “time-to-first-relapse”, “time-to-Magnetic-Resonance-Imaging (MRI)-activity” and “time-to-disability-progression”.
Results
1445 patients were enrolled (1039 on DMF, 406 on TRF) and followed for a median of 34 months. Patients on TRF were older (43.5 ± 8.6 vs 38.8 ± 9.2 years), with a predominance of men and higher level of disability (p < 0.001 for all). Patients on DMF had a higher number of relapses and radiological activity (p < .05) at baseline.
Time-varying Cox-model for the event “time-to-first relapse” revealed that no differences were found between the two groups in the first 38 months of treatment (HRt < 38DMF = 0.73, CI = 0.52 to 1.03, p = 0.079). When the time-on-therapy exceeds 38 months patients on DMF had an approximately 0.3 times lower relapse hazard risk than those who took TRF (HRt>38DMF = 3.83, CI = 1.11 to 13.23, p = 0.033). Both DMTs controlled similarly MRI activity and disability progression.
Conclusions
Patients on DMF had higher relapse-free survival time than TRF group after the first 38 months on
therapy.
