Active clinical trials for "Sclerosis"

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.

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.

The Primary objective of this study is to determine the incidence and pattern of serious infections, malignancies, and other serious adverse events (SAE) in participants with multiple sclerosis (MS) treated with Tysabri (natalizumab).

The purpose of this study is to determine if certain drugs commonly used to treat multiple sclerosis have an effect on bone health.

The current study aims to test an online, non-restrictive diet among persons with multiple sclerosis (MS). Diet is the number one searched second-line therapy among persons with MS, however there are currently no established dietary approaches to improve health and wellbeing among persons with MS. Participants will complete the 8-week diet program using an online application. The primary research question is whether the diet program is acceptable and can improve general health indicators including cholesterol, glucose, body weight, body fat as well as MS symptoms (i.e., walking, cognition, fatigue, and quality of life).

Natalizumab (NTZ) use in Multiple Sclerosis (MS) in highly active patients has been largely established during the last Rationale 10 years in both clinical trials and real-world practice. Along with its efficacy, NTZ use has been limited by potential risk of progressive multifocal leukoencephalopathy (PML). Thus, several studies have tried to assess how to minimize this risk. One suggested approach is to move from the standard interval dose (SID) of 4 weeks to an extended interval dose (EID) of 5 weeks or longer. Extending the dosing interval of NTZ has been practiced by some physicians with the intention of improving the benefit/risk of the treatment by reducing the exposure-dependent risk of progressive multifocal leukoencephalopathy (PML) while maintaining efficacy. We propose to retrospectively analyze data from clinical records coming from RRMS patients treated in France at 5 different centers; Caen, Nice, Bobigny and Toulouse hospitals as well as Percy Military Hospital, to evaluate the effectiveness of natalizumab EID in subjects who have previously been treated with natalizumab SID for 12 months, in relation to continued SID treatment. In the clinical practice of these centers, patients are shifted after minimum 12 months under SID to an EID of 6 weeks regardless antibody JC serum status. Clinical, magnetic resonance imaging (MRI) and serum anti-JCV antibody status data are collected when available. The objective of this study is to assess the efficacy in term of ARR and safety.

This is an observational cross-sectional study of Ocrelizumab or Ofatumumab administrations for Relapsing forms of Multiple Sclerosis (RMS) in selected sites in the US, the UK and Australia.
