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

Phase IV, proof-of-concept, randomized, open-label, multi-center, two-arm, 9-month study to evaluate the neuroprotective effects of Natalizumab (TYSABRI®) or Interferon beta-1a (AVONEX®) treatments initiated at the time of acute optic neuritis (AON) as measured by RNFL thickness from Optical Coherence Tomography in patients with Relapsing Remitting Multiple Sclerosis (RRMS).

This research sub-study is being completed as a part of the Multicenter, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study to Evaluate the Efficacy and Safety of PEGylated Interferon Beta-1a (BIIB017) in Subjects with Relapsing Multiple Sclerosis (Protocol #: NA_00028117). This substudy is being done to understand the efficacy of BIIB017 by measuring the nerve fiber thickness in the eye.

The purpose of this study is to determine if high-dose cyclophosphamide followed by a maintenance dose of glatiramer acetate is safe in patients with relapsing remitting multiple sclerosis (MS). The investigators hypothesize that institution of glatiramer acetate treatment following high-dose cyclophosphamide treatment will extend the period of disease free activity and further reduce the disability in patients with relapsing remitting multiple sclerosis. The investigators plan to investigate the properties of glatiramer acetate against the recurrence of MS disease activity following high dose cyclophosphamide induced cessation detectable autoimmunity. The investigators hypothesize that glatiramer acetate, given in the phase of immune reconstitution after high-dose cyclophosphamide, may bias the immune system to a more tolerated state, thus leading to more stable and potentially permanent remissions.

Brief Summary: 800 RRMS Subjects currently treated with Avonex or Copaxone will be randomized to either continue on their current therapy or receive Rebif therapy. The subjects will be followed for 2 years. The primary objective is to compare the time to worsening to a medium level of concern as defined by the Canadian Multiple Sclerosis Working Group (CMSWG) treatment optimization recommendations.

A 6 months prospective, randomized, multicenter, controlled, parallel-group, open-label study in RRMS patients to assess the impact of an individualized patient support program (PSP) on treatment satisfaction and to evaluate whether this individualized support improves satisfaction and with it adherence to medication compared to standard care.

The goal of this study is to show pattern differences of vasoreactivity and connectivity between Progressive Multiple Sclerosis and Relapsing Remitting Multiple Sclerosis, by the use of methods of advanced brain MRIs and the Diffusion Tensor Imaging , and correlate these differences with Clinical disability and cognitive disorder results.

Randomized study designed to look at the difference in relapse rates between patients remaining on their current interferon medication and those switched to Copaxone®

This randomized controlled trial will evaluate a web-based relapse management programme, which is easily accessible for people with multiple sclerosis. The trial is accompanied by a mixed-methods process evaluation and a health economic evaluation. It is expected that the programme will positively change patients' relapse management and strengthen their autonomy and participation.

The purpose of this study is to explore the cardiac pharmacodynamics, safety and tolerability of MT-1303 in healthy subjects.

The main purpose of the study is to evaluate the safety, tolerability, and pharmacokinetic profile of two intravenous infusions of BIIB033 administered two weeks apart in subjects with MS. Approximately 42 MS subjects are planned to be enrolled in the study in 7 separate groups (i.e., 6 subjects per group). Each subsequent group will be administered a higher dose of BIIB033. Before a higher dose group is allowed to start, a Drug Safety Review Committee will review all safety data from previous groups enrolled, as well as data from another study where BIIB033 is being administered to healthy volunteers (215HV101).
