Use Cases of Inebilizumab in Neurology & Rare Autoimmune Diseases

Neurology : In neurology applications, inebilizumab is primarily used as an intravenous CD19-targeting monoclonal antibody to treat neuromyelitis optica spectrum disorder (NMOSD), a rare autoimmune disease that affects the optic nerves and spinal cord. By depleting pathogenic CD19+ B cells that produce damaging autoantibodies, inebilizumab helps reduce relapse rates and neurological disability in adults with anti-AQP4 immunoglobulin-positive NMOSD, offering a targeted, long-term treatment option that was previously unavailable. It is administered under specialist neurologic care due to its immunosuppressive effects and monitoring requirements.
Immunology : In immunology settings, inebilizumab’s mechanism of action as a B-cell depleting therapy addresses dysregulated immune responses by reducing populations of CD19-expressing B cells, plasmablasts, and some plasma cells involved in abnormal autoantibody production. Beyond NMOSD, it has gained regulatory approval for immunoglobulin G4-related disease (IgG4-RD), a chronic inflammatory condition affecting multiple organs, demonstrating lowered disease activity and flare frequency. This makes inebilizumab a valuable therapeutic in immune-mediated inflammation beyond classical neurologic autoimmunity.
Rare Autoimmune Diseases : For rare autoimmune diseases, inebilizumab’s targeted anti-CD19 immunotherapy has expanded treatment options where traditional immunosuppressants offered limited efficacy. Its ability to selectively eliminate B cells producing harmful autoantibodies improves outcomes in conditions like IgG4-related disease and is being explored in other rare disorders, including generalized myasthenia gravis. The advantage lies in its precision and potential for durable disease control, offering patients improved quality of life in diseases with otherwise few approved therapies.
