Active clinical trials for "Multiple Sclerosis"

Evaluate a method of testing the strength of five key lower limb muscle groups using a hand-held strength gauge (dynamometer).

The purpose of the study is to research the association between receiving Tysabri® (natalizumab), interferon beta-1a, glatiramer acetate or not having any treatment for your MS and how it may or may not impact certain white blood cells and other immunological markers. This information may be useful in identifying risk factors in developing progressive multifocal leukoencephalopathy (PML). It does appear that the risk increases with the total number of natalizumab infusions. Patients who have not yet started a disease modifying therapy or who have been on one other than natalizumab are needed as controls to see how these biomarkers change. Patients at various stages of natalizumab treatment as well as natalizumab naïve are needed to allow for analysis of the change in potential markers over time.

This is an observational, non-controlled, multicentric, prospective study planned to be conducted in 66 subjects diagnosed with multiple sclerosis (MS) in 20 centres of Argentina. Fatigue is recognized as one of the most frequent symptoms of MS with a high incidence in MS subjects. The link between fatigue and the degree of disability and other manifestations of the disease, such as depression has not been yet clearly understood. Hence, this study aims to understand the way in which fatigue impairs the quality of life (QoL) of MS subjects. This epidemiologic study can contribute to a better understanding of the way in which fatigue correlates with depression and the intensity with which both situations impact on the QoL of MS subjects.

This is an observational, non comparative, non-randomised, open-label, retrospective, single centre study planned to collect the data of subjects diagnosed with multiple sclerosis (MS) as per Poser or McDonald criteria between 1997 and 2007 in Taiwan. The clinical features and annual relapse rate in the first five years after the onset of disease have been compared between conventional and optico-spinal MS in the earlier studies. This study aims to understand the clinical care pathway of MS subjects and facilitate the subject's diagnosis before converting to MS.

This is a multi-center, two-arm non-comparative, observational, 96 week Phase IV study to evaluate treatment adherence when using RebiSmart™ for self-injection of Rebif® in subjects with relapsing multiple sclerosis (RMS). Subjects who have a confirmed diagnosis of RMS using McDonald Criteria and meet the eligibility criteria during a screening period of up to 28 days will be provided with an electronic self-injection device (RebiSmart™) to inject Rebif® for 96 weeks. The main purpose of this study is to evaluate treatment adherence for subjects with RMS over 24 weeks of treatment when using RebiSmart™ for self-injection of Rebif® in a multi-dose cartridge.

Ampyra (dalfampridine-ER) was approved by the FDA (2010) for improving walking speed in persons with multiple sclerosis. This project seeks to determine if there are other benefits to taking dalfampridine besides an increase in walking speed. This is strictly an observational study and research staff will not be involved in any decisions to stop or start taking the medication.

The purpose of this study is to determine changes on overall gait as well as in multiple gait and balance parameters after withdrawal of dalfampridine-ER 10mg in MS subjects who are receiving the medication consistently for at least two weeks prior to screening.

The goal of this study is to enroll 1000 participants with a history of Multiple Sclerosis into the MURDOCK Study (Duke IRB Pro00011196) as well as into the Multiple Sclerosis Cohort study (Duke IRB Pro00023791). All 1000 participants will answer a 4-page questionnaire administered by a trained study coordinator which is designed to collect information on the participant's diagnosis of Multiple Sclerosis. The goal of the study is to seek genetic explanations for response to treatment, progression of the disease, and biomarker validation.

The primary objective of this study is to demonstrate that the incidence of progressive multifocal Leukoencephalopathy (PML) in natalizumab-treated participants who do not have detectable antibodies to John Cunningham virus (JCV) (antibody negative) is lower than in participants who have detectable antibodies to JCV (antibody positive). The secondary objectives of this study are to: Estimate the incidence of PML in natalizumab-treated participants who are anti-JCV antibody negative and anti-JCV antibody positive, based on a meta-analysis of data obtained from this study and other data sources; Define the prevalence of anti-JCV antibody in relapsing multiple sclerosis (MS) participants receiving natalizumab within the TYSABRI Outreach: United Commitment to Health (TOUCH) Prescribing Program; Determine changes in anti-JCV antibody status over time.

The Study analyses the influence of selected factors on adherence to Betaferon treatment in patients with early multiple sclerosis (MS). The Investigator will document the relevant medical data regarding multiple sclerosis at every hospital visit, the patient will fill in two questionnaires at every visit: one about coping with the disease and the other about anxiety and depression. The Study particularly looks at the role of the support of the patient given by the multiple sclerosis nurses.The nurse will provide additional standardised information at start of treatment and will regularly phone the patient to ask standardised questions about the general condition with regard to the treatment, the disease and social support. At the end of the Study it will be assessed if the supportive measures and the standards in terms of adherence management in the hospital have some influence to increase long-term treatment adherence.
