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

The primary objective of this study is to assess the efficacy of Ocrelizumab (OCR) in Relapsing Multiple Sclerosis patients who have been previously treated with natalizumab (NTZ) by evaluating relapse rate, progression on MRI and disability progression.

This is an observational, prospective, non-interventional, non-controlled study planned to be conducted in subjects with Relapsing-Remitting Multiple Sclerosis (RRMS). The purpose of this observational study is to determine the correlation between the degree of disability and sexual dysfunction; and between the sexual dysfunction and the quality of life (QoL) of subjects with Relapsing Remitting Multiple Sclerosis (RRMS) in Argentina.

The study is a two-year prospective observational study of patients treated with teriflunomide. The investigators will recruit up to 75 patients at baseline, based on the estimate that approximately 20% of these patients (~ 15 patients) will have evidence of disease activity at the end of the first year of treatment with teriflunomide, as determined by clinical evaluation (relapses) and MRI activity (new T2 hyperintense lesions). The investigators will assess the expression of a putative biomarker signature consisting of toll like receptor 2(TLR2), TLR4 and chemokine receptor 1 (CCR1) on CD4 T-subsets at baseline and at intervals on treatment with teriflunomide to determine whether expression of this biomarker signature on one or more CD4 T-subsets correlates with disease activity.

The purpose of this study is to investigate the safety of subcutaneous (SC) interferon beta therapies with regard to frequency of injection site reactions (ISR) and flu-like symptoms (FLS) as reported by the relapsing-remitting multiple sclerosis (RRMS) participants.

The primary purpose of this study is to evaluate the overall safety and efficacy of Tecfidera (Dimethyl Fumarate) as an oral treatment for Korean participants with relapsing-remitting multiple sclerosis (MS) under routine clinical practice.

Little is known about the potential effects of exercise on the underlying disease mechanisms in multiple sclerosis (MS). Although contactin-1 and contactin-2 are known as two proteins involved in axonal regeneration, it is unclear whether these proteins are induced by exercise in persons with MS (PwMS). The aim of this study was to determine the serum levels of contactin-1 and contactin-2 in PwMS and to investigate the change of these markers with exercise. Although contactin-1 and contactin-2 are known as two proteins involved in axonal regeneration, the mechanism of action of these proteins in MS patients has not been fully elucidated in the literature. The investigators' aim was to determine the serum levels of contactin-1 and contactin-2 in a group of relapsing-remitting multiple sclerosis (RRMS) patients and to evaluate the change of these markers with exercise. Thus, the investigators think that a valuable contribution will be made to the literature to shed light on the role of biomarkers in the mechanism mediating the beneficial effects of exercise in MS. In addition, as far as the investigators know, this study is the first to investigate the effect of exercise on contactin-1 and contactin-2 serum levels in MS patients.

Primary Aims: To determine how effective long term Natalizumab (NTZ) therapy is in slowing the progression of whole brain atrophy. Whole brain atrophy rates will be measured through magnetic resonance imaging (MRI) scans and compared between patients with Multiple Sclerosis (MS) who have been using NTZ for at least 2 years versus age and gender-matched healthy controls. The primary outcome will be whole brain atrophy rate measured as the percent change in brain volume (PBVC) over a two-year period. Primary hypothesis: The investigators hypothesize that long term (>2 years) NTZ therapy will slow the rate of whole brain atrophy in patients with Multiple Sclerosis (MS) (as measured by percent change in brain volume), reaching a whole brain atrophy rate similar to that of non-MS controls (a true "disease activity free" state).

To evaluate treatment tolerability, adherence and quality of life (QoL) over 1 year in MS (Multiple Sclerosis) participants who have been switched - due to persistent tolerability issues, particularly injection problems - from a subcutaneous injectable disease-modifying treatment (DMT) given several times a week (Rebif, Betaferon or Copaxone) to once weekly Avonex 30 μg given intra-muscularly. Avonex will be applied by the injection device Avonex Pen.

The objectives of this study are to assess the long-term safety and impact on disease activity and progression of natalizumab (Tysabri) in participants with relapsing remitting multiple sclerosis (RRMS) in a clinical practice setting.

The main goal of this investigator-initiated study is to evaluate the effectiveness and efficacy of Teriflunomide in a population of Relapsing Remitting Multiple Sclerosis (RRMS) patients treated in regular practice, over a period of at least two years, in the regular setting of a Multiple Sclerosis Clinic.
