Filter by:This study will look at the blood and cerebrospinal fluid of consented participants who either have early stage multiple sclerosis (clinically isolated syndrome) or who have later stage (secondary progressive multiple sclerosis), or participants who do not have any neurological or autoimmune illness. Biomarkers and microRNA will be assessed for group differences.
The primary purpose of this study is to assess the immune response to vitamin D supplementation at two doses (5,000 IU and 10,000 IU daily) in both healthy controls and patients with clinically isolated syndrome compared to placebo. Secondary endpoints include (1) disease outcome in the clinically isolated syndrome in terms of clinical relapses and evidence of new lesions on MRI (McDonald's MS), 2) Safety of doses used
REFLEXION is a double blind extension of the study 27025 (NCT00404352) (REFLEX). The purpose of the study is to obtain long-term follow-up data in subjects with clinically definite multiple sclerosis (MS) and subjects with a first demyelinating event at high risk of converting to MS, treated with fetal bovine serum [FBS]-free/human serum albumin [HSA]-free formulation of interferon [IFN]-beta-1a (RNF).
The definition of the most 'at-risk' population within highly susceptible groups would provide an opportunity for preemptive therapeutics. A convenient, safe, and tolerable therapy that delays the onset of clinical disease during the pre-symptomatic stage of demyelinating disease would provide a therapeutic alternative to a 'wait and see' approach in subjects at 'high risk' for CIS (clinically isolated syndrome - monosymptomatic demyelinating disease) or MS. Identical twins share the same genes and have the highest rate of shared MS. An identical female with a sister twin with MS has a 34% chance of having MS. Non concordant (no MS yet) identical (monozygotic - from the same sperm-egg zygote) female twins provide an ideal population to find out what factors predict the onset of MS in the non-affected twin. We will recruit 30 identical female twins, one with MS and the other without MS, and obtain brain MRI and biological samples on the non-affected twin and determine if: - the presence of characteristic MS-like lesion(s) on baseline MRI predisposes to MS. - specific proteins in blood or cerebrospinal fluid predispose to the clinical expression of demyelinating disease If we can predict by simple tests (MR brain scan and blood tests) the likelihood of the onset of MS in 'at risk' subjects, and have safe and tolerable therapies, we may be able to prevent the clinical onset of demyelinating disease (MS).
The primary objective of this initiative is to assess the effectiveness of subcutaneous (sc) interferon (IFN) beta - 1a, (Rebif®), versus No Treatment in delaying the conversion to Clinically Definite Multiple Sclerosis (CDMS) - as defined by the occurrence of a second exacerbation - over 96 weeks in subjects that present with Clinically Isolated Syndrome (CIS) accompanied by an abnormal magnetic resonance imaging (MRI). The secondary objectives are to: - Assess the effectiveness of sc IFN beta - 1a (Rebif®) therapy in reducing the proportion of patients with CIS converting to CDMS - Assess the safety of sc IFN beta - 1a (Rebif®) in the patients with CIS
The purpose of the study is to determine whether giving intravenous dexamethasone every 4 weeks during the first 12 months of weekly Avonex dosing will reduce the progression of functional impairment, brain atrophy, relapse rate and frequency, and new and enlarging brain lesions over the first 24 months of Avonex therapy in patients with relapsing-remitting or mono-symptomatic multiple sclerosis.
