Active clinical trials for "Multiple Sclerosis"

The study will determine the effect of 400 mg once daily of ketoconazole at steady state on the pharmacokinetics of a single oral dose of GSK239512 in young healthy volunteers. Ketoconazole is a strong inhibitor of CYP3A4, which is involved in metabolism of drugs. A two-cohort design will be applied with cohort 1 aimed at providing a first estimate of the interaction potential of GSK239512 and ketoconazole in terms of pharmacokinetic parameters in a small number of subjects. Data from Cohort 1 will inform the decision of which dose to use in Cohort 2, in which a larger number of subjects will be exposed to GSK239512 without and with ketoconazole. The target maximum exposure is aimed to be similar to the exposure by a single dose of 80 mcg of GSK239512 without CYP3A4 inhibition. In summary, the results from this study will help to estimate the maximum increase in exposure of GSK239512 during concomitant use of strong CYP3A4 inhibitors and will help define the subsequent dosing strategy around GSK239512 and co-medications with potential to inhibit CYP3A4.

The study will assess the patients' satisfaction of treatment after 12 months treatment with fingolimod It also will assess the tolerability profile of fingolimod in a small population.

The purpose of this study is to explore the cardiac pharmacodynamics, safety and tolerability of MT-1303 in healthy subjects.

The main purpose of the study is to evaluate the safety, tolerability, and pharmacokinetic profile of two intravenous infusions of BIIB033 administered two weeks apart in subjects with MS. Approximately 42 MS subjects are planned to be enrolled in the study in 7 separate groups (i.e., 6 subjects per group). Each subsequent group will be administered a higher dose of BIIB033. Before a higher dose group is allowed to start, a Drug Safety Review Committee will review all safety data from previous groups enrolled, as well as data from another study where BIIB033 is being administered to healthy volunteers (215HV101).

The primary objective of the study was to evaluate the immunogenicity of natalizumab (Tysabri®) produced by a modified manufacturing process (natalizumab high titer; BG00002-E) administered intravenously (IV) to participants with relapsing forms of multiple sclerosis (MS). The secondary objective of this study was to evaluate the safety of natalizumab high titer.

This study will use positron emission tomography (PET) to measure a brain protein called peripheral benzodiazepine receptor (PBR) in patients with multiple sclerosis. PBR is created during the inflammation process, and brain inflammation is a key feature of multiple sclerosis (MS). PBR usually affects one type of brain cell, but it can also cause damage to surrounding areas of the brain in patients with MS. PET studies of PBRs and brain inflammation may help elucidate the role of these brain cells in patients with MS. Healthy normal volunteers and patients with MS between 18 and 70 years of age may be eligible for this study. Patients with MS must have had onset of disease between 18 and 40 years of age. Patients with MS undergo the following procedures: Visit 1: Medical history, physical examination, blood tests and magnetic resonance imaging (MRI). Visit 2: Blood tests and PET scan. Visits 3 and 4: MRI and physical examination. Visit 5: PET scan and blood tests. Visit 6: MRI and physical examination. Healthy volunteers undergo the following: Visit 1: Medical history, physical examination, blood tests. Visits 2 and 3: PET and blood tests. Magnetic Resonance Imaging MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the subject lies on a table that can slide in and out of the scanner (a metal cylinder), wearing earplugs to muffle loud knocking noises that occur during the scanning process. The procedure lasts about 90 minutes; the patient is asked to lie still for up to 25 minutes at a time. The subject can communicate with the MRI staff at all times during the scan. During part of the scan a contrast agent is administered through a catheter (plastic tube) placed in an arm vein to enhance the images. Positron Emission Tomography (PET) The PET scan gives information on brain and body chemistry and function. The subject lies on a bed that slides in and out of the doughnut-shaped scanner. A catheter is placed in a vein in the arm and another is placed in an artery in the wrist or elbow area. The catheter in the arm is used for injecting a radioactive material that the scanner detects, and the other is used to collect blood samples. A custom-molded plastic mask is used to support the head and prevent it from moving during the procedure. The subject may be asked to perform various tasks during the PET scan or to lie quietly. The scan lasts about 2.5 hours.

The purpose of this study was to determine whether a group wellness intervention or individualized physical rehabilitation was more effective in improving health and physical activity in persons with multiple sclerosis.

People with mobility disabilities are at greater risk than the general population for incurring health problems. Many of these conditions are preventable through behavior and lifestyle changes such as exercise and physical activity. Recent evidence suggests that people with disabilities experience the same physiologic response to exercise as the general population. Nonetheless, nearly three-fourths of those with disabilities report being entirely sedentary or not active enough to achieve health benefits. Despite some knowledge of issues that limit physical activity among this population, few studies have investigated methods for promoting physical activity adoption among people with disabilities, including wheelchair users. The purpose of this study is to test the effectiveness of a behavioral intervention to promote physical activity adoption over 6 months and maintenance of physical activity over another 6 months by community-dwelling manual wheelchair users.

The purpose of this study is to evaluate the efficacy of Sativex® compared with placebo in reducing the daily number of episodes on incontinence.
