Active clinical trials for "Multiple Sclerosis"

Significant data from placebo-controlled clinical trials have demonstrated the efficacy of Rebif in relapsing remitting multiple sclerosis (RRMS) with reduction in relapse rate, delay in disability progression, and reduction in magnetic resonance imaging (MRI) activity and accumulation of lesion burden. Multiple sclerosis (MS), a chronic neurological diseases, can have diverse effects on the lives of subjects and their families. In controlled clinical trials, clinical measurement in MS has focused on impairments of neurological assessment using Expanded Disability Status Score (EDSS). The assessment of the impact of MS on the non-physical aspect of dysfunction is not often measured, or reported. Furthermore, traditional clinical measures have not been able to assess the effects of neurological illness on quality of life (QoL), which is becoming an increasingly important topic to neurologists treating subjects with varied neurological conditions. This observational, one arm, multicentric study is aimed to assess the usefulness of the Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL) instrument in comparison with the Multiple Sclerosis Quality of Life-54 instrument (MSQOL-54 questionnaire) in RMS subjects on Rebif therapy and to assess the effectiveness of Rebif therapy using health related quality of life (HRQoL) measures.

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.

This study is primarily designed to evaluate the impact of AVONEX PEN autoinjector on work capacity of participants with multiple sclerosis (MS) starting on this device. This study will also evaluate as secondary endpoints various patient-reported outcomes over the short-term (1 month), including adherence, treatment satisfaction and convenience, and the long-term (12 and 24 months), including adherence, persistence, quality of life (QOL), treatment satisfaction and convenience. It will also assess health resource utilization by MS participants starting on AVONEX PEN autoinjector, as well as overall safety/tolerability, and will correlate all secondary outcomes with the primary (i.e., work capacity).

Non-adherence to the treatment regimen is a common problem associated with injectable drugs (e.g. Betaferon) that are used in multiple sclerosis patients. Certain patients omit single injections or even totally discontinue therapy that normally should be long-term. It is therefore crucial to identify the factors which have the most significant effect on regularity of administration of Betaferon and the risk of premature discontinuation of treatment in order to undertake appropriate preventive measures. This study is conducted in routine practice setting and aims to identify those risks. Pre-defined risk factors associated with technical aspects of the treatment, support provided to the patient, stage of the disease and possible adverse effects of the medication are checked on a quarterly basis with a questionnaire method. Monitoring of omitted doses of the prescribed medication (Betaferon) is carried out by the study nurse.

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.

To establish a pharmacokinetic (PK) profile of BG00012, as measured by its primary metabolite, monomethyl fumarate (MMF), during a 24-hour dosing period in subjects with relapsing-remitting multiple sclerosis (RRMS), with a variety of baseline demographic characteristics.

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 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.

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.
