- Abstract
Background and Objectives: In multiple sclerosis (MS), MRI markers can measure the potential neuroprotective effects of fingolimod beyond its anti-inflammatory activity. In this study we aimed to comprehensively explore, in the real-word setting, whether fingolimod not only reduces clinical/MRI inflammatory activity, but also influences the progression of irreversible focal and whole brain damage in relapsing-remitting [RR] MS patients., Methods: The "EVOLUTION" study, a 24-month observational, prospective, single-arm, multicenter study, enrolled 261 RRMS patients who started fingolimod at 32 Italian MS centers and underwent biannual neurological assessments and annual MRI evaluations. Study outcomes included the proportions of evaluable RRMS patients achieving at 24 months: (1) no new/enlarging T
2 -hyperintense white matter (WM) lesions and/or clinical relapses; (2) a modified classification of "No Evidence of Disease Activity 4" ("modified NEDA-4") defined as no new/enlarging T2 -hyperintense WM lesions, clinical relapses, and 6-month confirmed disability progression, and a yearly percentage lateral ventricular volume change on T2 -FLAIR images < 2%; (3) less than 40% of active lesions at baseline and month 12 evolving to permanent black holes (PBHs)., Results: At month 24, 76/160 (47.5%; 95% confidence interval [CI] = 39.8%;55.2%) RRMS patients had no clinical/MRI activity. Thirty-nine of 170 RRMS patients (22.9%; 95% CI = 16.6%;29.3%) achieved "modified NEDA-4" status. Forty-four of 72 RRMS patients (61.1%; 95% CI = 49.8%;72.4%) had less than 40% of active WM lesions evolving to PBHs. The study confirmed the established safety and tolerability profile of fingolimod., Discussion: By comparing our results with those from the literature, the EVOLUTION study seems to indicate a neuroprotective effect of fingolimod, limiting inflammatory activity, brain atrophy and PBH development., (© 2024.
