A Clinical Trial to Investigate the Long-term Safety and Tolerability, Efficacy, Pharmacodynamics,...
Multifocal Motor Neuropathy (MMN)This trial is an extension of the antecedent trial ARGX-117-2002. It is a multicenter trial that has been designed to evaluate the long-term safety and tolerability, efficacy, immunogenicity, Pharmacokinetics (PK), and Pharmacodynamics (PD) of ARGX-117 Intravenously (IV) in adults with Multifocal Motor Neuropathy (MMN). The trial will include a double-blinded rollover treatment period (DTP), an open-label treatment period (OTP), and a safety follow-up period.

OCS-05 in Patients With Acute Optic Neuritis
Optic NeuritisOptic; Neuritis1 moreTo evaluate the safety and tolerability of OCS-05 compared to placebo in patients with acute optic neuritis (AON) receiving the standard of care

Edaravone in the Treatment of Aquaporin-4 Antibody-positive Optic Neuritis
Optic NeuritisEdaravone 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.

Assessment of Clemastine Fumarate as a Remyelinating Agent in Acute Optic Neuritis (ReCOVER)
Optic NeuritisThe 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.

Physical Therapy on Non-structural Medial Elbow Pain
Elbow Injuries and DisordersNeuritis5 moreThis study is investigating the effect of using a regional interdependence approach of managing non-structural elbow pain with physical therapy.

Fampridine-SR and Optic Neuritis Recovery
Optic NeuritisOptic 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.

A Clinical Trial to Investigate the Safety and Tolerability, Efficacy, Pharmacokinetics, Pharmacodynamics...
Multifocal Motor NeuropathyThis is a phase 2, randomized, double-blinded, placebo-controlled, parallel-group, multicenter trial to evaluate the safety and efficacy of 2 dose regimens of ARGX-117 versus placebo, in participants with MMN previously stabilized with IVIg (intravenous immunoglobulin).

Assessment and Treatment of Patients With Long-term Dizziness in Primary Care
DizzinessVertigo1 moreBrief Summary: The purpose of the present study is to examine the effects of a Group based intervention consisting of vestibular rehabilitation (VR) combined with cognitive behavioral therapy (CBT) in patients with long--lasting vestibular dizziness. The study also aims to describe sociodemographic, physical and psychological characteristics in the patients, and to examine prognostic factors related to functional status and disability following participation in the intervention. Prior to the RCT, a feasibility study will be conducted to examine the feasibility of the study protocol.

A Study of TAK-771 in Japanese Participants With Chronic Inflammatory Demyelinating Polyradiculoneuropathy...
Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)Multifocal Motor Neuropathy (MMN)The main aim of the study is to check for side effects from TAK-771, and to check how well TAK-771 controls symptoms in Japanese participants with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy (MMN) The participants will be treated with TAK-771 for 45 months as a maximum. There will be many clinic visits. The number of visits will depend on the infusion cycles of study drug (every 2, 3, or 4 weeks).

Optic Neuritis Differential Diagnosis Study
Optic NeuritisNeuromyelitis Optica1 moreBackground: 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.
