Neuromyelitis Optica Spectrum Disorder (NMOSD): Understanding

Neuromyelitis Optica Spectrum Disorder (NMOSD): Overview

Neuromyelitis optica spectrum disorder (NMOSD), formerly known as neuromyelitis optica or Devic's disease, was initially thought to be a variant of multiple sclerosis but is now recognized as a distinct autoimmune disorder characterized by inflammation of the optic nerves and spinal cord. Advances in immunology led to the discovery of aquaporin-4 immunoglobulin G antibodies (AQP4-IgG), which are present in many affected patients and have expanded the clinical definition of the disease. Today, NMOSD encompasses a broader spectrum of neurologic disorders beyond classical optic neuritis and transverse myelitis, reflecting its complex and evolving nature.

Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune condition that targets the optic nerves and spinal cord, leading to a wide array of neurological symptoms. A hallmark feature is optic neuritis, which presents as eye pain, blurred vision, or vision loss. Transverse myelitis can cause limb weakness, numbness, and sensory disturbances due to spinal cord inflammation. Some patients may experience area postrema syndrome, characterized by persistent nausea, vomiting, and hiccups due to brainstem involvement. Additional symptoms include bladder or bowel dysfunction, muscle spasms, fatigue, and cognitive changes such as brain fog or mood disturbances.

Neuromyelitis Optica Spectrum Disorder (NMOSD) is an inflammatory autoimmune condition that primarily targets the optic nerves and spinal cord, with frequent involvement of the brainstem, particularly the area postrema. The disease is strongly associated with IgG antibodies against aquaporin-4 (AQP4), a water channel protein concentrated on astrocyte foot processes in key areas of the central nervous system. These antibodies are present in 60% to 90% of patients and are highly specific for NMOSD. The autoimmune response leads to perivascular lymphocytic infiltration, astrocyte damage, demyelination, and axonal loss, particularly in regions rich in AQP4 such as the optic nerves, spinal cord, and circumventricular zones like the periaqueductal gray matter.

Due to the rarity of NMOSD, standardized treatment guidelines are limited, but most approaches involve an initial short course of high-dose intravenous corticosteroids, such as methylprednisolone, to manage acute relapses. In refractory cases, plasmapheresis or intravenous immunoglobulin may be employed. Long-term management focuses on preventing relapses through chronic immunosuppressive therapy, with first-line agents including azathioprine and rituximab. Second-line treatments like mycophenolate mofetil and methotrexate are also used, often offering the advantage of less frequent dosing. Newer biologic therapies targeting IL-6, complement proteins, or AQP4-IgG are being explored for their specificity and effectiveness. Proper differentiation from multiple sclerosis is crucial, as certain MS therapies can worsen NMOSD.

Neuromyelitis Optica Spectrum Disorder (NMOSD) Emerging Drugs Chapters

This segment of the Neuromyelitis Optica Spectrum Disorder (NMOSD) report encloses its detailed analysis of various drugs in different stages of clinical development, including Phase III, II, I, Preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Neuromyelitis Optica Spectrum Disorder (NMOSD) Emerging Drugs

• BAT4406F: Bio-Thera Solutions

BAT4406 is an investigational ADCC-enhanced anti-CD20 mAb candidate in clinical development for the treatment of autoimmune diseases. BAT4406F is currently being evaluated in NMOSD, an orphan indication with an estimated prevalence of 0.5 to 10 per 100,000. BAT4406 is a type I glyco-engineered mAb that binds specifically to CD20 on B-cells, kills the B-cells by CDC, and enhances ADCC effect. B cells have been implicated in the pathogenesis of a number of autoimmune diseases, including the CNS disorders, multiple sclerosis (MS) and NMOSD. Depletion of B-cells could provide meaningful relief for these autoimmune diseases. NMOSD is an autoimmune inflammatory disorder of the central nervous system (CNS) with preferential localization to the optic nerve, spinal cord and brain stem. Patients typically experience bouts of vision loss or blindness, attacks of myelitis with often severe motor impairment including loss of ambulation, sensory disturbances, bowel/bladder dysfunction, and brainstem attacks with characteristic episodes of intractable nausea, vomiting and hiccups. Currently, the drug is in Phase III stage of its development for the treatment of Neuromyelitis Optica Spectrum Disorder (NMOSD).

• B001: Shanghai Jiaolian Drug Research and Development Co., Ltd

B001 is a recombinant humanized anti-CD20 monoclonal antibody developed by Shanghai Jiaolian Drug Research & Development (originating from Shanghai Pharmaceuticals Holding). It works by targeting CD20 on B cells and triggering antibody-dependent cellular cytotoxicity (ADCC) to deplete autoreactive B cells, a mechanism aligned with current NMOSD treatment goals. Designed for intravenous administration, B001 aims to reduce disease relapses in AQP4-IgG positive NMOSD through sustained B-cell suppression. It also shows potential across other autoimmune neurologic conditions and B-cell malignancies, illustrating a broad therapeutic strategy rooted in targeted immunotherapy. Currently, the drug is in Phase II/III stage of its development for the treatment of Neuromyelitis Optica Spectrum Disorder (NMOSD).

• CT103A cells: Nanjing IASO Biotherapeutics

Equecabtagene Autoleucel (Eque-cel) is an innovative fully human anti-BCMA CAR-T cell therapy which uses lentivirus as a gene vector to transfect autologous T cells. The CAR contains a fully human scFv, CD8a hinge and transmembrane, and 4-1BB co-stimulatory and CD3ζactivation domains. Based on rigorous molecular structure screening and comprehensive in vitro and in vivo functional evaluations, Eque-cel demonstrates rapid and potent efficacy, accompanied by exceptional long-term persistence in vivo, enabling patients to achieve higher and deeper responses. Currently, the drug is in Phase I stage of its development for the treatment of Neuromyelitis Optica Spectrum Disorder (NMOSD).
