Active clinical trials for "Multiple Sclerosis"

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.

Study Design: Phase 4, pilot, single center, observational study. MEP's will be obtained twice, two weeks apart at baseline and every 6 months for 36 months (total of 14 sessions of MEP's) MEP's will include: Onset latencies and CMCT to bilateral abductor pollicis brevis and tibialis anterior muscles MEP amplitudes and the ratio of the central to peripherally obtained motor amplitudes (MEP-M ratio) to bilateral abductor pollicis brevis and tibialis anterior muscles Clinical measures (EDSS, MEP's, T25FWT, 6MWT, 9HPT) will be obtained at baseline and every 6 months for 36 months. Study location: Single center in Canada Study Objectives: Primary: To evaluate the reliability of MEP's in Alemtuzumab treated MS patients over a 36 month period. Secondary: To determine the degree of correlation between MEP's and presently used clinical measures of efficacy (EDSS, 6MWT, T25FWT, 9HPT) and to determine if MEP's can predict who will require a third cycle of Alemtuzumab.

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.

Most experts in the field consider Multiple Sclerosis as the main auto immune disease of the central nervous system. In spite of many works, the data in the literature concerning the antigens targeted by the CD8+ T-Cell response are still contradictory and insufficient.

To evaluate the usability of positron emission tomography imaging as a novel outcome measure in multiple sclerosis studies

The aim of this study is to determine whether prophylactic vaccines recommended are effective and safe in patients with multiple sclerosis(MS) under MS-specific therapy.

Researchers from the University of South Florida's Rehabilitation Engineering program are looking for volunteers to participate in a research study for experimental evaluation of wheelchair-mounted robotic arms (WMRAs). Participants will operate commercially available and developmental WMRAs in a physical test environment. The study will serve to identify desirable design features of WMRAs and input devices so that future production systems may further increase the quality of life of potential users. The study will also promote both the justification of prescribing WMRAs to enhance quality of life through the proposed standard testing method, and awareness for the emerging assistive robotics industry.

This study intends to explore evolution of MSRV expression by analyzing the levels of MSRV transcripts in blood, as well as the levels of the MSRV-Env protein in serum of MS patients. The study will be conducted over one year in four cohorts of patients with different forms of MS (remitting-relapsing MS i.e. RRMS, primary-progressive MS i.e. PPMS and secondary-progressive MS i.e. SPMS) and in clinically isolated syndrome (CIS) patients who have suffered a single clinical event but do not comply with diagnosis criteria for definite MS. The MSRV RNA and MSRV-Env protein levels will be correlated with the clinical evolution of patients and with the reverse transcriptase activity, inflammatory markers assessed by cytokines levels. A control group of healthy subjects will be included (the study, GN-E-003, is performed in parallel and is part of another dedicated protocol).

The purpose of this observational study is to collect long-term data on safety and effectiveness of fingolimod, particularly including clinical disease and patient outcome related parameters such as relapse and disability, in patients who have participated in prior trials within the fingolimod clinical development program. Furthermore, this study explores the incidence of selected safety related outcomes of fingolimod treatment during follow-up visits within the context of routine medical practice.

Study Title: A Serologic Study to Correlate b-IFN NAb titers to b-IFN Induced Biomarker Response in Patients with Multiple Sclerosis Objectives: Subjects currently on any of the three b-IFN preparations (Avonex (Interferon b-1a 30 mcg IM Q 7 days), Rebif (Interferon b-1a 22 or 44mcg SC TIW), or Betaseron (Interferon b-1b 250mcg SC QOD)) will be enrolled to one of 3 groups: Group 1: Approximately 200 subjects will be enrolled who are NAb+ (titer ³ 20NU/ml) Group 2: Approximately 50 subjects will be enrolled who are BAb- (titer <8U) and NAb- (titer <20 NU/ml) Group 3: Approximately 50 subjects will be enrolled who are BAb+ (titer ³8U) and NAb- (titer <20 NU/ml) The primary objective of this study is to compare baseline b-IFN induced MxA mRNA response in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients. Secondary objectives are: To compare b-IFN induced MxA mRNA response in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients at the month 6 visit. To compare b-IFN induced biomarker response (viperin, IFIT1) in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients (data compared at baseline and month 6 visits) To compare b-IFN induced biomarker response (MxA, viperin, IFIT1) in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. BAb+ (titers ³8U)/NAb- (titers <20 NU/ml, Group 3) patients at baseline and month 6 visits. To correlate NAb titer levels with b-IFN induced biomarker response (data taken from baseline and month 6 visits from Group 1). To compare b-IFN induced biomarker response (MxA, viperin, IFIT1) in BAb-/NAb- patients (Group 2) vs. BAb +/NAb- patients (Group 3) in order to determine if BAbs affect b-IFN induced biomarker response (data compared at baseline and month 6 visits). Tertiary objectives are: 1. To explore patient characteristics that may predict NAb positivity. Design: This is a multi-center, open-label study of approximately 300 (200 NAb+ and 100 NAb- (50 BAb+ and 50 BAb-)) MS patients that will compare b-IFN induced biomarker response following b-IFN injection in neutralizing antibody positive vs. antibody negative patients. Study Population: Approximately 300 subjects (200 in Group 1, 50 in Group 2, and 50 in Group 3) will be recruited for the study. Inclusion Criteria: To be eligible for entry into this study, candidates must meet all of the following eligibility criteria at the time of randomization: Patients (male or female) diagnosed with relapsing forms of MS.

Unwillingness or inability to comply with the requirements of this protocol including the presence of any condition (physical, mental, or social) that is likely to affect the subject's ability to comply with the study protocol. Any other reasons that, in the opinion of the Investigator, the subject is determined to be unsuitable for enrollment into this study.
