Filter by:Study Title: A Serologic Study to Correlate b-IFN NAb titers to b-IFN Induced Biomarker Response in Patients with Multiple Sclerosis Objectives: Subjects currently on any of the three b-IFN preparations (Avonex (Interferon b-1a 30 mcg IM Q 7 days), Rebif (Interferon b-1a 22 or 44mcg SC TIW), or Betaseron (Interferon b-1b 250mcg SC QOD)) will be enrolled to one of 3 groups: Group 1: Approximately 200 subjects will be enrolled who are NAb+ (titer ³ 20NU/ml) Group 2: Approximately 50 subjects will be enrolled who are BAb- (titer <8U) and NAb- (titer <20 NU/ml) Group 3: Approximately 50 subjects will be enrolled who are BAb+ (titer ³8U) and NAb- (titer <20 NU/ml) The primary objective of this study is to compare baseline b-IFN induced MxA mRNA response in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients. Secondary objectives are: 1. To compare b-IFN induced MxA mRNA response in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients at the month 6 visit. 2. To compare b-IFN induced biomarker response (viperin, IFIT1) in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. antibody negative (NAb-, titers < 20NU/ml, BAb-, titers <8U, Group 2) patients (data compared at baseline and month 6 visits) 3. To compare b-IFN induced biomarker response (MxA, viperin, IFIT1) in neutralizing antibody positive (NAb+, titers ³ 20NU/ml, Group 1) vs. BAb+ (titers ³8U)/NAb- (titers <20 NU/ml, Group 3) patients at baseline and month 6 visits. 4. To correlate NAb titer levels with b-IFN induced biomarker response (data taken from baseline and month 6 visits from Group 1). 5. To compare b-IFN induced biomarker response (MxA, viperin, IFIT1) in BAb-/NAb- patients (Group 2) vs. BAb +/NAb- patients (Group 3) in order to determine if BAbs affect b-IFN induced biomarker response (data compared at baseline and month 6 visits). Tertiary objectives are: 1. To explore patient characteristics that may predict NAb positivity. Design: This is a multi-center, open-label study of approximately 300 (200 NAb+ and 100 NAb- (50 BAb+ and 50 BAb-)) MS patients that will compare b-IFN induced biomarker response following b-IFN injection in neutralizing antibody positive vs. antibody negative patients. Study Population: Approximately 300 subjects (200 in Group 1, 50 in Group 2, and 50 in Group 3) will be recruited for the study. Inclusion Criteria: To be eligible for entry into this study, candidates must meet all of the following eligibility criteria at the time of randomization: 1. Patients (male or female) diagnosed with relapsing forms of MS. 2. Currently being treated with the same b-IFN (in accordance with FDA approved dosing and schedules) for 12 to 48 months inclusive. 3. All levels of disability 4. Age 18-65 years inclusive 5. Subjects must be willing to be followed for the 6-month study period. Exclusion Criteria: Candidates will be excluded from study entry if any of the following exclusion criteria exist at the time of study initiation. 1. Patients with prior b-IFN NAb test (whether positive or negative). 2. Patients who are currently being treated or have been treated within 6 months prior to screening with combination therapy (b-IFN plus any other immunosuppressant/immunomodulatory) other than IV steroids (either pulse or for a relapse). 3. Unwillingness or inability to comply with the requirements of this protocol including the presence of any condition (physical, mental, or social) that is likely to affect the subject's ability to comply with the study protocol. 4. Any other reasons that, in the opinion of the Investigator, the subject is determined to be unsuitable for enrollment into this study. Treatment Groups: This is a multi-center, open-label study of approximately 300 (200 NAb+ patients and 100 NAb- patients (50 BAb+ and 50 BAb-)) relapsing MS patients that will compare b-IFN induced biomarker response following b-IFN injection in neutralizing antibody positive vs. antibody negative patients. Subjects currently on any of the three b-IFN preparations (Avonex (Interferon b-1a 30 mcg IM Q 7 days), Rebif (Interferon b-1a 22 or 44mcg SC TIW), or Betaseron (Interferon b-1b 250mcg SC QOD)) will be enrolled to one of 3 groups: Group 1: Approximately 200 subjects will be enrolled who are NAb+ (titer ³ 20NU/ml) Group 2: Approximately 50 subjects will be enrolled who are BAb- (titer <8U) and NAb- (titer <20 NU/ml) Group 3: Approximately 50 subjects will be enrolled who are BAb+ (titer ³8U) and NAb- (titer <20 NU/ml)
The purpose of this study is to determine the effectiveness of a new treatment for multiple sclerosis (MS), a serious disease in which the immune system attacks the brain and spinal cord. MS can be progressive and severe and lead to significant disability. The study treatment involves the use of high-dose chemotherapeutic drugs to suppress the immune system. The participant's own (autologous) blood-forming (hematopoietic, CD34+) stem cells are collected before the chemotherapy is given, and then transplanted back into the body following treatment. Transplantation of autologous hematopoietic stem cells is required to prevent very prolonged periods of low blood cell counts after the high-dose chemotherapy.
Bladder dysfunction occurs at some time in most patients with multiple sclerosis and these patients are prone to have recurrent urinary tract infections. Cranberry has been traditionally used for the treatment and prophylaxis of urinary tract infections but there is no reliable randomized controlled trial demonstrating evidence of cranberry's utility in this disease. The aim of our study is to assess the efficacy and safety of cranberry in the prophylaxis of urinary tract infections in patients with multiple sclerosis with a prospective randomized, double-blind and placebo-controlled clinical trial.
Multiple sclerosis is disease believed to be due to immune cells, cells which normally protect the body, but are now attacking the tissue in the brain and possibly the spinal cord. The likelihood of progression of this disease is high. This study is designed to examine whether treating patients with high dose cyclophosphamide and CAMPATH-1H (drugs which reduce the function of the immune system) followed by return of previously collected blood stem cells will stop the progression of your multiple sclerosis. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the cyclophosphamide and CAMPATH-1H is to destroy the cells in your immune system which are thought to be causing your disease. The purpose of the stem cell infusion is to restore the body's blood production, which will be severely impaired by the high dose chemotherapy and to produce a normal immune system that will no longer attack the body.
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.
The primary objective of this study is to determine the safety and the immunogenicity of extended treatment with natalizumab when administered at a dose of 300 mg intravenously (IV) to subjects with multiple sclerosis (MS) who have completed natalizumab Studies C-1801, C-1802, or C-1803.
Multiple sclerosis (MS) is at onset an immune-mediated demyelinating disease. In most cases, it starts as a relapsing-remitting disease with distinct attacks and no symptoms between flares. Over years or decades, virtually all cases transition into a progressive disease in which insidious and slow neurologic deterioration occurs with or without acute flares. Relapsing-remitting disease is often responsive to immune suppressive or modulating therapies, while immune based therapies are generally ineffective in patients with a progressive clinical course. This clinical course and response to immune suppression, as well as neuropathology and neuroimaging studies, suggest that disease progression is associated with axonal atrophy. Disability correlates better with measures of axonal atrophy than immune mediated demyelination. Therefore, immune based therapies, in order to be effective, need to be started early in the disease course while MS is predominately an immune-mediated and inflammatory disease. While current immune based therapies delay disability, no intervention has been proven to prevent progressive disability. We propose, as a randomized study, autologous unmanipulated PBSCT using a conditioning regimen of cyclophosphamide and rabbit antithymocyte globulin (rATG) versus FDA approved standard of care (i.e. interferon, glatiramer acetate, mitoxantrone, natalizumab, fingolimod, or tecfidera) in patients with inflammatory (relapsing) MS despite treatment with alternate approved therapy.
The therapy with Interferon-ß-1b reduces the inflammatory component of multiple sclerosis with positive effects on the disease course. The 8 MUI dose at alternate days is kept constant for years. About 1/3 of patients suspend treatment by three years due to side effects or suspected or accepted ineffectiveness. The main objective of the study is to verify the safety and effectiveness of a cyclical administration (a month of suspension after two of treatment) from the beginning of treatment. There is the possibility that a scheme envisaging therapy free intervals can reduce the onset of negative feedbacks (antagonising the drug therapeutic effect) compared to the standard administration protocol. This might also result in an increase of the drug effectiveness and/or in a longer duration of effectiveness itself. Finally, cyclical administration allows patients to spend actual periods of "therapeutic vacation", with positive psychological effects.
- The study primarily investigates the effect of copaxone on fatigue during treatment, compared to baseline in patients with relapsing-remitting multiple sclerosis. - Secondary outcome measures are:disability, relapse rate, quality of life and depression.
