Active clinical trials for "Multiple Sclerosis"

The primary objective of this study is to assess the effect of natalizumab compared to fingolimod on the evolution of new on-treatment T1-gadolinium-enhancing (Gd+) lesions to persistent black holes (PBH) over 52 weeks. The secondary objectives of this study in this study population are to assess the effect of natalizumab compared to fingolimod on: magnetic resonance imaging (MRI) measures of central nervous system (CNS) tissue destruction as measured by the number of new T1-Gd+ lesions; various other MRI measures of disease activity; No Evidence of Disease Activity (NEDA); Relapse on treatment over 52 weeks; The change in information processing speed as measured by the Symbol Digit Modalities Test (SDMT).

In this research study, the investigators will determine whether a procedure called Extracorporeal Photopheresis (ECP) is helpful in preventing progression of disability in people with SPMS when compared to monthly corticosteroid infusions. This study will determine whether ECP has an effect on inflammatory cells in people with SPMS and whether it has a beneficial therapeutic effect.

This study evaluated disease control during different lengths of treatment transition from natalizumab to fingolimod.

Fatigue is one of the most frequent symptoms reported by multiple sclerosis (MS) patients and is often a significant source of disability. Unlike normal fatigue, multiple sclerosis related fatigue (MSRF) occurs independently of activity level, suggesting that it is due to dysfunction in the neural pathways that regulate the perception of energy although the precise cause is still not understood. While MSRF can be managed through lifestyle modifications and with drug treatment, these measures are commonly either ineffective or only partially effective. Administration of the male sex hormone testosterone has been shown to improve energy levels in males with testosterone-deficiency states. Testosterone also reduces fatigue in patients with other medical conditions not associated with low testosterone levels, suggesting that this treatment may also be useful in symptomatic control of MSRF. This proposed seven-month long clinical trial is designed to test the hypothesis that administration of oral testosterone tablets to male MS patients will result in an improvement of fatigue relative to the administration of placebo tablets. As fatigue is frequently reported by MS patients to be one of their most frustrating and disabling symptoms, any proven additional treatment option for MSRF would be beneficial in improving quality of life.

The primary objective of this study is to evaluate the immunogenicity of natalizumab (BG00002) 300 mg subcutaneous (SC) administered to participants with relapsing multiple sclerosis (RMS). The secondary objectives of the study are to evaluate the safety of natalizumab SC injections and to evaluate the efficacy of natalizumab SC injections on relapses and on new magnetic resonance imaging (MRI) lesions.

Primary Objectives: To assess the efficacy of vatelizumab compared to placebo as measured by a reduction in new contrast-enhancing lesions (CELs) in relapsing remitting multiple sclerosis (RRMS) patients. To evaluate multiple doses of vatelizumab for a dose-response. Secondary Objectives: To evaluate the safety and tolerability of vatelizumab compared to placebo. To evaluate the pharmacokinetics (PK) of vatelizumab.

To evaluate the efficacy and safety of AIN457 versus placebo in patients with relapsing multiple sclerosis.

Background: - Secondary-progressive multiple sclerosis (SP-MS) is the chronic phase of multiple sclerosis (MS). The majority of people who have relapsing-remitting MS eventually develop SP-MS. There are currently no effective treatments for SP-MS. Researchers are interested in determining whether the drug rituximab, which is used to treat rheumatoid arthritis and some types of cancer, is able to target certain white blood cells that are thought to play a role in the progression of SP-MS. To ensure that the rituximab will reach the brain and spinal cord, participants will receive it by intravenous drip and by intrathecal injection (through a lumbar puncture into the cerebrospinal fluid). Objectives: - To evaluate the safety and effectiveness of combined intravenous and intrathecal rituximab in individuals with secondary-progressive multiple sclerosis. Eligibility: - Individuals between 18 and 65 years of age who have been diagnosed with SP-MS and have been off any form of immunosuppressive therapy for at least 3 months. Design: - The study will involve a 1-year pretreatment baseline series of visits, followed by a 2-year treatment period. Participants will provide blood samples throughout treatment as directed by the study researchers, and additional studies may be performed during the study period if participants consent to further investigation.

The study is being done to determine if venous angioplasty is an effective treatment for chronic cerebrospinal venous insufficiency (CCSVI). In this condition, areas of narrowing or blockages are present in the internal jugular or azygos veins (veins which drain blood from the central nervous system) and these blockages may be associated with symptoms classically attributed to MS. Therefore, angioplasty may help to improve the symptoms associated with CCSVI and multiple sclerosis (MS). In this study, the investigators will evaluate the effectiveness of angioplasty in the treatment of CCSVI by comparing two the outcomes of two groups of patients: one group with CCSVI diagnosed on a venogram and treated with angioplasty and one group with CCSVI diagnosed on a venogram but not treated. The patients enrolled in this study, and the neurologist evaluating patients after the procedure, will not know whether or not they were treated with angioplasty.

The investigators principal hypothesis is that INO and optic neuritis are objective, quantitative, and reproducible models for corroborating the hypothesis that changes in core body temperature are associated with the reversible and stereotypic decay in axonal conduction and that ACTHAR can serve to prevent such changes. The application of ocular motor and optic nerve measures appears to constitute a useful paradigm to detect and monitor responses to therapeutic strategies that stabilize nerve cell membranes in response to temperature induced decay in axonal conduction mechanisms, with implications on activities of daily life that are dependent upon vision (reading, driving, walking, work performance).
