Active clinical trials for "Multiple Sclerosis"

This is a multicenter study conducted in 3 parts. Part A is a double-blind placebo-controlled parallel-group period, and Part B and C are open-label extension periods. The primary objective of the double-blind study (Part A) is to assess the effect of Prolonged-Release Fampridine treatment on walking speed as measured by the T25FW (timed 25 foot walk) in Japanese participants with Multiple Sclerosis. The secondary objective of the double-blind portion of the study is to evaluate the safety and tolerability of prolonged-release Fampridine in this study population. The primary objective of the open-label extension study (Part B) is to evaluate the long-term safety profile of prolonged-release Fampridine. The primary objective of the additional open-label extension (Part C) is to provide participants who complete the study with continued access to prolonged-release fampridine until marketed drug can be used at the applicable site or until sponsor decision to discontinue the study.

The primary outcome of the study is to evaluate the cumulative area under the concentration time curve (AUC) over 2 weeks, as measured by AUC from time 0 to 336 hours post dose (AUC0-336h), for serum concentrations of BIIB017 and Rebif. The secondary outcomes are to evaluate the maximum observed serum concentrations (Cmax) of BIIB017 and Rebif and to evaluate the safety and tolerability of BIIB017 and Rebif over 2 weeks in healthy volunteers.

The aim of this study is to study the comparison between the effects of supplementation with 25000 IU preformed vitamin A (retinyl palmitate) or placebo for 6 months on immune system and Th1/Th2 balance in patients with Multiple Sclerosis.

This randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with interferon beta-1a (Rebif) in participants with relapsing multiple sclerosis. Participants will be randomized to receive either ocrelizumab 600 mg or matching placebo intravenous (IV) as 300 mg infusions on Days 1 and 15 for the first dose and as a single infusion of 600 mg for all subsequent infusions every 24 weeks, with placebo injections matching interferon beta-1a SC three times per week; or interferon beta-1a 44 mcg SC injections three times per week (with placebo infusions matching ocrelizumab infusions every 24 weeks). Planned duration of double-blind treatment is 96 weeks. Participants who complete the 96-week double-blind treatment will have an option to enter a single-group, active-treatment, open-label extension period, providing they fulfill the eligibility criteria.

The study is designed to determine the effect of weekly intramuscular (IM) administration of 30 mcg Avonex (interferon beta 1a) on safety parameters and gadolinium (Gd) enhanced and T2-weighted cranial magnetic resonance imaging (MRI) lesions in Chinese patients with clinically diagnosed (using revised McDonald criteria) relapsing multiple sclerosis (MS).

The incidence of tremor in Multiple Sclerosis (MS) has been estimated to affect up to 2/3rds of patients. Over half of the tremors involve the upper limb and frequently lead to further disability. Medical treatment of MS tremor is generally unrewarding, although carbamazepine, clonazepam, glutethimide, hyoscine, isoniazid, ondansetron, primidone, and tetrahydrocannabinol have been reported to have some beneficial effect but published evidence of effectiveness is very limited. The investigators' experience to date suggests that many of the upper limb tremors may potentially be responsive to Botulinum toxin injection therapy. Aims: 1. The investigators aim to determine the efficacy of commonly used doses of BOTOX on the patients with symptomatic unilateral or bilateral arm tremor due to MS; and any side effects associated with this treatment.

This study is to find out if Interferon-beta (IFN-beta) can recover its effectiveness after a washout period in patients with Multiple Sclerosis who have previously developed neutralizing antibodies to Interferon-Beta

To evaluate the tolerability of a new formulation of rebif and Betaseron in subjects with relapsing-remitting multiple sclerosis (RRMS) by comparing the mean change in injection site pain scores from pre-injection to 30 minutes post therapy administration.

Determination the efficacy of daily oral treatment with laquinimod 0.6 mg capsules as compared to placebo in subjects with Relapsing Remitting Multiple Sclerosis (RRMS).

The purpose of this study is to determine whether nabilone (Cesamet) when used as an adjunctive agent with gabapentin (Neurontin) provides significantly improved pain relief over gabapentin alone for the management of neuropathic pain in MS.
