Active clinical trials for "Optic Neuritis"

To evaluate the safety and tolerability of OCS-05 compared to placebo in patients with acute optic neuritis (AON) receiving the standard of care

Edaravone showed a good effect on promoting remyelination and protecting axons in NMOSD animals. The investigators hypothesize that edaravone can inhibit axonal damage in patients with aquaporin-4 antibody-positive optic neuritis.

The main purpose of this study is to assess clemastine as a remyelinating agent in patients with acute optic neuritis.The study will also evaluate the tolerability of clemastine, originally approved as first-generation antihistamine, in patients with optic neuritis. Study procedures will include assessments for evidence of remyelination in the anterior visual pathway and in the brain using electrophysiologic techniques and magnetic resonance imaging. If they are on one, patients in this study can remain on their standard disease modifying treatment during the course of the study. However, patients cannot participate in any other investigational new drug research study concurrently.

Optic Neuritis (ON) is a condition that occurs in approximately 50% of individuals with relapse remitting MS, and is the presenting event in 15-20% of patients who go on to develop MS. These ON events present with a decline in vision over several days with painful eye movements. The purpose of this study is to collect pilot data on the effect of Fampridine-SR on the recovery of visual function after demyelinating optic neuritis.Our team evaluated a person with ON who had incomplete recovery which was quite bothersome to her. After a one-month treatment course Fampridine SR,her visual functioning improved. Based on this case, we present a unique opportunity to evaluate the potential benefit of Fampridine-SR as a potential treatment for persons who do not fully recover from acute ON.

This study will explore the expression of PARP-1 in optic neuritis of multiple sclerosis patients. The data will be collected from Sohag University hospital in the period from the start of August 2021 to the end of December 2021. The study protocol will be approved by the Scientific Research Ethical Committee, Faculty of Medicine, Sohag University.

Background: Optic neuritis is a frequent cause of vision loss encountered by ophthalmologists in the Caribbean. The diagnosis is made on clinical grounds. Optic neuritis can occur either in an isolated manner or, most often, as the first symptom of multiple sclerosis (MS) or neuromyelitisoptica (NMO). These 2 demyelinating disorders differ by many means, including treatment and prognosis. MS can cause severe long-term disability while NMO is a short-term sight- and life-threatening condition causing potential relapses, which may require plasma exchanges. Furthermore, disease-modifying therapies used in NMO are different from those used in MS, which can worsen the natural history of NMO. Early differential diagnosis of these diseases is thus crucial for preventing severe visual loss and disability.

The aim of the project is to create a new, non-invasive and safe protocol for the early diagnosis of various types of optic neuropathies with the use of diffusion magnetic resonance imaging

In neuroinflammatory diseases of the central nervous system (CNS) such as multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD) and anti-MOG antibody-associated disorders (MOGAD), neuronal degeneration is the consequence of inflammatory and demyelinating lesions in the brain, optic nerve and spinal cord. Both white and grey matter are systematically affected. Lesions of the perivascular spaces containing cerebrospinal fluid (CSF) and meningeal inflammation seem to play an important role in the pathophysiology of these neuroinflammatory diseases. Currently, the interrelation of all these aspects is not clearly established in the pathophysiology of these diseases. In order to better understand the mechanisms that lead to and underlie the clinical disability of patients with these diseases, we need in vivo study models that allow the in-depth study of the neurodegenerative process and the identification of its causes. In this perspective, we make the hypothesis that the visual pathways model is very relevant to measure neuro-axonal loss and to explore the different mechanisms involved in neurodegeneration during MS and other CNS demyelinating diseases. Researchers have at their disposal many tools that allow them to analyse and quantify the neurodegenerative process in a reproducible and very precise manner from a structural and functional point of view, while taking into account possible vascular involvement (MRI, optical coherence tomography - angiography, etc…).

This study seeks to determine the biologic causes of inflammation in patients with Transverse Myelitis (TM) Neuromyelitis Optica Spectrum Disorder (NMOSD) and related conditions. While patients will be treated according to decisions with their treating physician, this study will collect data and samples from patients prospectively to gain a better understanding of the disease. We are seeking to understand why some patients respond to medications, while others do not. We also seek to understand what happens biologically, preceding relapses. Gathering these data and samples will allow researchers to identify new ways of diagnosing and treating these diseases. Data and samples will be shared with researchers around the world to support collaborative efforts to treat these conditions.

The Swiss-Ped-IBrainD is a national patient registry that collects information on diagnosis, symptoms, treatment, and follow-up of pediatric patients with an inflammatory brain disease in Switzerland. It was first implemented in 2020 in the pediatric clinic of the university hospital in Bern. Further centers all over Switzerland were opened for recruitment in 2021; Aarau, Basel, Bellinzona, Chur, Geneva, Lausanne, Lucerne, St. Gallen, and Zurich. The center in Winterthur is expected to be open for recruitment by autumn 2021. The registry provides data for national and international monitoring and research. It supports research on inflammatory brain diseases in Switzerland and the exchange of knowledge between clinicians, researchers, and therapists. The registry aims to improve the treatment of children with inflammatory brain diseases and optimizing their health care and quality of life.
