Filter by:The investigators' hypothesis is that measuring the PCTdynamics would be an easy and reliable symptom to evaluate in pathologies affecting the optic nerve
The goal of the study is to determine the earliest structural changes in the optic nerve during the acute event and during the twelve months of recovery following Acthar treatment.
This clinical trial aims at preventing visual dysfunction and optic nerve degeneration associated with autoimmune optic neuritis by systemic i.v. administration of 33.000 IU erythropoietin over 3 days. The primary objective is to determine the efficacy of erythropoietin compared to placebo given as add-on to methylprednisolone as assessed by measurements of retinal nerve fibre layer thickness and low contrast visual acuity 6 months after acute optic neuritis.
Following acute inflammation of the optic nerve region, as commonly seen in multiple sclerosis patients, the optic nerve often undergoes atrophy, thus representing permanent damage. Data from animal studies suggest that amiloride may prevent this process. The aim of this study is to assess a potential neuroprotective effect of amiloride in acute autoimmune inflammation of the optic nerve region.
Background: - Optic neuritis often is a symptom of multiple sclerosis (MS). Many people who experience optic neuritis are later diagnosed with MS. MS disease activity seen on magnetic resonance imaging (MRI) scans is often greater than that seen in tests given during regular doctor's visits. Even though MRI is a helpful tool for studying optic neuritis and MS, more information is needed on how MS symptoms show up on MRI scans. Researchers want to use MRI scans to track changes in the optic nerve after an optic neuritis episode. This approach will help them study the relationship between optic neuritis and MS. Objectives: - To collect more information about the relationship between optic neuritis and multiple sclerosis. Eligibility: - Individuals between 18 and 50 years of age who have new optic neuritis. - Individuals between 18 and 50 years of age who have new symptoms of MS other than optic neuritis. - Healthy volunteers between 18 and 50 years of age. Design: - Participants will be screened with a physical exam and medical history. They may provide blood or urine samples. - Participants with optic neuritis or other MS symptoms will have a baseline study visit. They will have a physical exam and full eye exam. To look for signs of MS, they will have evoked potential tests to see how the body responds to stimulation. They will also have an MRI scan to study any changes in the brain and optic nerves. - After the first visit, participants will have steroid treatment for 5 days for the optic neuritis. - Additional study visits will be given 1, 3, 6, 9, and 12 months after the baseline visit. The tests from the first visit, including the MRI scans, will be repeated at these visits. - Healthy volunteers will have a baseline study visit. They will have a physical exam and full eye exam. They will have evoked potential tests to see how the body responds to stimulation. They will also have an MRI scan to study any changes in the brain and optic nerves. - Healthy volunteers will have additional study visits 2 and 11 months after the baseline visit. The tests from the first visit, including the MRI scans, will be repeated at these visits.
We hypothesize that the novel melanocortin-mediated anti-inflammatory effects of ACTH will reduce axonal loss following ON by limiting inflammatory optic nerve injury. We will compare the effect of ACTH and intravenous methylprednisolone therapy on axonal injury following ON using OCT, a sensitive, reproducible and noninvasive tool to measure RNFL thickness. The primary outcome will be the average RNFL thickness at 6 months. Additional pre-specified statistical analyses will compare the difference in the mean RNFL thickness at 6 months in the affected eye between the IV methylprednisolone- and Acthar-treated groups, and the mean 6-month affected eye RNFL thicknesses adjusted for the baseline unaffected eye RNFL. The secondary outcome measure will examine the frequency of optic nerves with RNFL swelling between the IV methylprednisolone- and Acthar-treated groups at 1 and 3 months. A predefined exploratory outcome will compare the ganglion cell plus inner plexiform layer (GC+IPL) thickness at 6 months between treatment groups. Additional tertiary outcome will be the assessment of changes in fatigue, mood, visual function depression, and quality of life in patients with AON. Assessment will be completed by administration of the following questionnaires: Modified Fatigue Impact Scale, Multiple Sclerosis Quality of Life 54 Instrument, 25-item Visual Function Questionnaire with 10-item supplement, Beck's Depression Inventory. These questionnaires have been validated for the MS (AON) population. Descriptive and correlative analysis will be done at each visit time point to assess for QOL for this study population.
Patients diagnosed with Multifocal Motor Neuropathy were confirmed based on the European Federation of Neurological Societies/ Peripheral. Nerve Society Guideline. Patients who meet all inclusion criteria and do not conflict with the exclusion criteria will receive NPB-01 (intravenous immunoglobulin) 400mg/kg/day for five consecutive days. Subsequently, patients receive NPB-01 1g/kg every 3weeks and evaluate the Medical Research Council（MRC） score and the Guy's Neurological Disability Scale（GNDS） et al. As a safety endpoint, the safety of NPB-01 will be investigated the occurrence of adverse events by one year after the start of the study treatment.
Optic neuritis (ON) is a common event in Multiple Sclerosis (MS), and causes significant loss of nerve cells in the eye, resulting in poor vision. Optic neuritis also provides a sensitive way of testing the effectiveness of drugs that may help protect from loss of nerve cells in ON and therefore in MS. The investigators have identified through laboratory and early clinical research in humans that amiloride (a water tablet already in use) may be a drug that can be of benefit in optic neuritis by protecting from loss of nerves cells, ie a neuroprotective drug. The purpose of this study is to assess the efficacy of amiloride as a neuroprotective drug in optic neuritis
To evaluate the efficacy and safety of fingolimod 0.5mg versus placebo in patients with suspected acute demyelinating optic neuritis (ADON) receiving standard steroid treatment
The primary objective of the study is to evaluate the efficacy of BIIB033 in subjects with their first episode of unilateral Acute Optic Neuritis (AON). The secondary objective of this study in this study population is to assess the safety, tolerability, and pharmacokinetics (PK) of BIIB033.
