Active clinical trials for "Multiple Sclerosis"

Multiple Sclerosis is the first cause of neurological handicap in France. The importance of cognitive disabilities, their evaluation and their impact on patients' life have only been comprehended recently. Immunosuppressants represent new treatments in Multiple Sclerosis (MS) but imply a lot of constraints. This study will evaluate the impact of these treatments on cognitive disabilities, tiredness state, emotion and quality of life in general, on a lengthened period.

Biogen Idec has developed a novel process to manufacture Interferon beta-1a (INFB), the active ingredient of Avonex®, that does not include fetal bovine serum (FBS). This bioequivalence study is being conducted to confirm the pharmacokinetic (PK) and pharmacodynamic (PD) comparability of Interferon beta-1a produced by the currently approved serum-containing process and Interferon beta-1a produced by the new serum-free manufacturing process.

The study is planned to evaluate the cognitive functions in subjects with RRMS treated with interferon beta-1a, and its relationship to the fatigue and neurological dysfunction status.

The present study aims to assess the adherence to therapy with interferon beta-1a (Rebif®) and at investigating potential factors that are involved in its outcome, in a representative sample of patients with relapsing remitting multiple sclerosis (RRMS), under real life conditions.

This Phase 4 pilot cross-sectional descriptive/exploratory study is to be conducted in clinical practice settings (including MS (Multiple sclerosis) specialty clinics, general neurology practices, or other academic or private practice settings) in the United States to assess the psychometric properties of the ARMS questionnaire in approximately 100 adult patients with MS who are experiencing a confirmed relapse, as identified by the investigator or designee at each site. Neither efficacy nor safety of treatment will be evaluated in this study. The ARMS questionnaire is a 2-part, 2-page survey, with each part comprising 7 questions on 1 page. Part 1 is designed to evaluate the patient's relapse symptoms and how the symptoms affect daily activities and overall function, as well as patient's response to past treatments for previous relapses, as a means of guiding treatment selection. Part 2 is designed to evaluate treatment response in terms of symptom relief and functioning, as well as treatment tolerability. Part 1 of the survey is to be completed when the patient presents with new relapse of MS. Part 2 of the survey is to be completed 1 month (± 1 week) after initiation of treatment for relapse of MS. Treatment for relapse will be at the sole discretion of the investigator.

This is an open-label study of patients with relapsing forms of Multiple Sclerosis designed to assess the biochemical, immunological and pharmacokinetic profiles of a large, actively infusing natalizumab patient population. A duration effect for progressive multifocal leukoencephalopathy (PML) risk associated with natalizumab therapy appears to exist. There is minimal data available to understand this effect at the biochemical and cellular level. The purpose of this study is to gather preliminary data on several parameters to guide in more focused research on the duration effect.

Prospective Observational Long-term Safety Registry of Multiple Sclerosis Participants who Have Participated in Cladribine Clinical Trials

Determine patient satisfaction with the single-use autoinjector for the delivery of pre-filled Avonex syringe.

The primary objective is to assess the pharmacokinetic (PK) profile of natalizumab (Tysabri) at steady state. The secondary objective is to assess the pharmacodynamics (PD) profile (α4 integrin saturation) of Tysabri at steady state.

It is difficult to determinate prognostic criteria of Multiple Sclerosis with conventional MRI insofar as physiopathology is not well-known: the precise sequences of events leading to plaque formation and axonal injury are still not completely understood. Some elements involved in plaque formation can be studied thanks to MR techniques (cerebrospinal fluid and periveinular spaces, neuronal injury, microglia, and cerebral microcirculation's dysfunction). This study aims at giving a better understanding of MS plaques' physiopathology, using data from modern MRI through a longitudinal followed up with weakly MR 3T examination.
