Background: We hypothesized that differences in access to disease-modifying treatments (DMTs) could explain the association between socioeconomic status and disability progression in multiple sclerosis (MS).

Objective: This study aimed to analyze the association between education level and DMT use in France.

Methods: All patients from OFSEP network with MS onset over 1996-2014 and aged ⩾ 25 years at onset were included.

Background: Studies have reported an association between socioeconomic status and disability progression in multiple sclerosis (MS), but findings using the pre-MS individual socioeconomic status are missing.

Objective: The objective was to investigate the association between education level and disability progression.

Methods: All Observatoire Français de la Sclérose en Plaques (OFSEP) patients with MS clinical onset over 1960-2014, and aged ⩾25 years at MS onset were included.

Article Synopsis
  • * Results from the NOVA clinical trial show that while patients on Q6W dosing had lower levels of natalizumab compared to Q4W dosing, they still maintained significant clinical efficacy with most patients experiencing stable disease markers over 72 weeks.
  • * Key findings included a 23.6% increase in soluble vascular cell adhesion molecule-1 (sVCAM-1) levels in the Q6W

Article Synopsis
  • The study aimed to compare disability progression between primary progressive multiple sclerosis (PPMS) patients treated with anti-CD20 therapies (rituximab and ocrelizumab) and a control group that was untreated.
  • Data was gathered retrospectively from the French MS registry, including factors like time to confirmed disability progression (CDP), relapse rates, and MRI activity in patients from 2016 to 2021.
  • Results showed no significant difference in CDP or MRI activity between treated and untreated groups, although a trend suggested treated patients might experience fewer relapses, warranting further investigation.

Introduction: Following NOVA (part 1) and the approval of the subcutaneous (SC) route of administration of natalizumab by the European Medicines Agency, an extension phase of the NOVA phase IIIb study (part 2) was initiated to collect patient preference data for SC versus intravenous (IV) dosing in patients receiving every-6-week (Q6W) dosing of natalizumab. This study was performed to evaluate patient preference for SC versus IV natalizumab administration and explore the efficacy, safety, and pharmacology characteristics of both routes of administration.

Methods: In part 2, participants received natalizumab (Tysabri) 300 mg via IV infusion Q6W for 36 weeks and then were randomized to 48 weeks of crossover treatment (24 weeks SC Q6W and 24 weeks IV Q6W, or vice versa).
