Active clinical trials for "Multiple Sclerosis, Relapsing-Remitting"

The primary objective of this study is to define the effect of Tysabri in patients with relapsing-remitting (RR) multiple sclerosis (MS) over 2 years. The investigators will also explore the extent of remyelination in MS patients treated with Tysabri over 2 years. A secondary objective of this study is to investigate differences in the capacity for remyelination between patients who do or do not respond to Tysabri monotherapy during the same 24 months. A tertiary objective of this study is to monitor Tysabri effect in MS antiphospholipid antibodies positive and MS antiphospholipid antibodies negative patients and to determine perfusion differences according to the antiphospholipid antibodies positivity status.

Natalizumab is a humanized monoclonal antibody directed against Very Late Activation Antigene 4 (VLA-4) and has a potent effect on disease activity in multiple sclerosis (MS). A blockade of VLA-4 with natalizumab may not only interfere with autoimmunological processes but also with central nervous system (CNS) immune surveillance.

The aim of this study is to develop novel magnetic resonance imaging (MRI) protocols suitable for patients with multiple sclerosis using advanced MRI such as rotating frame relaxation imaging. In addition, the investigators want to study the correlation between advanced MRI parameters and clinical disease progression.

The primary objective of the study is to evaluate the real-world clinical effectiveness, as measured by the proportion of participants relapsed at 12 months, in participants treated with dimethyl fumarate (DMF). Secondary objectives of the study are: To evaluate the real-world clinical effectiveness, as measured by the proportion of participants relapsed at 12 months, in participants treated with DMF, glatiramer acetate (GA), teriflunomide, or fingolimod both in the overall participant cohort and in a subset of participants who were naïve to disease-modifying therapy (DMT) and were diagnosed with multiple sclerosis (MS) within 3 years of starting the index therapy; To compare relapse activity, defined as annualized relapse rate (ARR), among participants treated with DMF, GA, teriflunomide, or fingolimod; To compare MS-related hospitalizations among participants treated with DMF, GA, teriflunomide, or fingolimod; To compare intravenous corticosteroid use among participants treated with DMF, GA, teriflunomide, or fingolimod.

The purpose of this single visit extension study is to explore immune status in RRMS patients treated for at least 48 months with fingolimod. Long-term changes in T cell counts will be compared to short-term changes in immune status (baseline to month 6) after treatment start with fingolimod as assessed in the original Biobank study (CFTY720DDE01).

The purpose of this observational study is to evaluate the effectiveness, safety and health related quality of life of Generic DMF (Sclera® or Marovarex ®, Hikma) in patients undergoing routine clinical care for RRMS in MENA Region

The primary objective is to compare oral dimethyl fumarate (DMF) persistence at six months in relapsing-remitting multiple sclerosis (RR-MS) participants initiating DMF with and without OroSEP patient support program (PSP), respectively. The secondary objectives are: to compare oral DMF persistence at one month and three months in RR-MS participants initiating DMF with and without OroSEP PSP, respectively; To compare oral DMF adherence at six months in RR-MS participants initiating DMF with and without OroSEP PSP; To compare at three months and six months the reason of oral DMF discontinuation, in the two groups; To describe the percentage of participants with treatment-related adverse events globally and by class of adverse events, in the two groups of participants; To assess the evolution of participants' anxiety globally and to compare it at inclusion and at six months in participants with and without OroSEP PSP, respectively; To describe participants' satisfaction regarding oral DMF initiation and follow-up globally at six months and to compare it in patients with and without OroSEP PSP, respectively; For OroSEP PSP group: To assess participants' satisfaction regarding their participation in OroSEP PSP at six months; To assess neurologists' satisfaction regarding their participation in OroSEP PSP, after the last participant last visit of center.

The incidence of autoimmune conditions is at least 2-3 times higher in Multiple Sclerosis population than in general population. These MS patients category response unfavorably to the Interferon. The investigators suggest that autoimmune co morbidity can serve as a biological marker predicting good response to GA.

This was an open-label, multicentric, prospective, post-marketing surveillance (PMS) study on the extent to which subject compliance is influenced by use of a variable titration regimen at the start of treatment of relapsing MS with Rebif.

Significant data from placebo-controlled clinical trials have demonstrated the efficacy of Rebif in relapsing remitting multiple sclerosis (RRMS) with reduction in relapse rate, delay in disability progression, and reduction in magnetic resonance imaging (MRI) activity and accumulation of lesion burden. Multiple sclerosis (MS), a chronic neurological diseases, can have diverse effects on the lives of subjects and their families. In controlled clinical trials, clinical measurement in MS has focused on impairments of neurological assessment using Expanded Disability Status Score (EDSS). The assessment of the impact of MS on the non-physical aspect of dysfunction is not often measured, or reported. Furthermore, traditional clinical measures have not been able to assess the effects of neurological illness on quality of life (QoL), which is becoming an increasingly important topic to neurologists treating subjects with varied neurological conditions. This observational, one arm, multicentric study is aimed to assess the usefulness of the Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL) instrument in comparison with the Multiple Sclerosis Quality of Life-54 instrument (MSQOL-54 questionnaire) in RMS subjects on Rebif therapy and to assess the effectiveness of Rebif therapy using health related quality of life (HRQoL) measures.
