Active clinical trials for "Multiple Sclerosis, Relapsing-Remitting"

This is an open-label, randomized, multicenter, comparative, and parallel-group study comparing the therapeutic effects of two interferon-beta-1a regimens in relapsing-remitting multiple sclerosis (MS). The primary objective is to demonstrate the superiority of Rebif® 44 microgram (mcg) subcutaneous injection given three times a week (132 mcg per week) to that of Avonex® 30 mcg intramuscular injection given once a week.

The purpose of this study is to determine whether the use of EGb 761 by patients with Relapsing-Remitting Multiple Sclerosis is effective in improving cognition, when compared to placebo.

This study assessed the efficacy, safety, and tolerability of 2 doses of oral fingolimod (1.25 mg/day and 0.5 mg/day) compared to placebo in patients with relapsing-remitting multiple sclerosis (RRMS)

This is a Phase II, randomized, double-blind, parallel group, placebo controlled, multicenter study to evaluate the safety and efficacy of Rituximab in adults with RRMS.

The purpose of this study is to determine whether raising low levels of the natural antioxidant uric acid by the administration of a precursor, inosine, has any therapeutic effect on the progression of Relapsing Remitting Multiple Sclerosis (RRMS) and secondary progressive Multiple Sclerosis (MS).

This is a randomized, rater blinded trial in patients who interrupt treatment with natalizumab with or without being treated with other immunomodulatory drugs, or continue treatment with natalizumab. The main purpose of this study is to find out the following, when participants stop taking natalizumab for 24 weeks: when MS symptoms return, and if other drugs for MS may help control MS symptoms during the natalizumab-interruption period. This study will also explore how quickly the effects of natalizumab return after resuming natalizumab dosing.

A randomized, multi-center, double-blind, proof-of-concept study to assess the effect of multiple infusions of AIN457 (10 mg/kg) versus placebo on disease activity as measured by MRI scans over a 24 week period in patients with relapsing-remitting multiple sclerosis

This open-label extension study will evaluate the long-term safety of glatiramer acetate and its effect on the neurologic course of participants with relapsing-remitting multiple sclerosis (RRMS). Participants have scheduled visits every 3 months to assess glatiramer acetate safety and their Multiple Sclerosis (MS) status.

Therapeutic strategies for multiple sclerosis (MS) are essentially based on the use of immunomodulatory agents such as interferon b and glatirmere acetate, but their efficacy is quite limited, they are not well tolerated and they have a very high cost. Recent works showed an immunomodulatory effects of HMG-CoA reductase inhibitors (the so-called "statins"). In experimental allergic encephalopathy, a murine model of MS, statins inhibit the onset and progression of the disease through a shift from Th1 towards Th2 cytokine production. Other in vitro studies suggest the ability of statins to inhibit the lymphocyte migration through the blood brain barrier. Furthermore, in an open labeled human study in MS, statin regimen was associated with a decreased lesional activity assessed by MRI. Statins are well tolerated drugs, used for many years, with a low cost and with a putative efficacy in MS. The investigators suggest to test the pravastatin safety and efficacy on MRI criteria in a double-blind, placebo-controlled study in 40 patients with a relapsing-remitting MS.

Phase I study aiming at: assessing the absolute bioavailability, pharmacokinetic profile, and dose proportionality of interferon beta-1a (HSA-free solution in pre-filled syringes) after i.v. and s.c. administration as well as the pharmacodynamic profile to create the link with available surrogate markers investigated with both formulations used clinically, lyophilisate with HSA (HSA+) and solution without HSA (HSA-); gathering further information on safety and tolerability of interferon beta-1a over dose range,including local and systemic tolerance, body temperature, vital signs, and a battery of exploratory sickness behavior tests.
