Inebilizumab, sold under the brand name Uplizna, is a medication for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adults. [7] [8] [4] Inebilizumab is a humanized mAb that binds to and depletes CD19+ B cells including plasmablasts and plasma cells. [4]

Contents

The most common adverse reactions include urinary tract infection, headache, joint pain (arthralgia), nausea and back pain. [7] [4]

Inebilizumab was approved for medical use in the United States in June 2020, [7] [9] in the European Union in April 2022, [6] and in Canada in December 2023. [1] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication. [10]

Medical uses

Inebilizumab is indicated for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adults with a particular antibody (patients who are anti-aquaporin-4 or AQP4 antibody positive). [7] [4]

Neuromyelitis optica spectrum disorder is a rare autoimmune disorder in which immune system cells and autoantibodies attack and damage the optic nerves and spinal cord. [7] Neuromyelitis optica spectrum disorder can be associated with antibodies that bind to a protein called aquaporin-4 (AQP4). Binding of the anti-AQP4 antibody appears to activate other components of the immune system, causing inflammation and damage to the central nervous system. [7] Clinically, the disease is manifested with attacks/relapses that result in neurological impairment such as blindness, paraplegia, sensory loss, bladder dysfunction, and peripheral pain. The disability from each attack is cumulative, making neuromyelitis optica spectrum disorder a chronically debilitating and potentially life-threatening disease. [11]

Side effects

The label for inebilizumab includes a warning for infusion reactions, potential depletion of certain proteins (hypogammaglobulinemia), and potential increased risk of infection — including progressive multifocal leukoencephalopathy, and potential reactivation of hepatitis B and tuberculosis. [7] [4]

The most common adverse reactions in the neuromyelitis optica spectrum disorder clinical trial were urinary tract infection, headache, joint pain (arthralgia), nausea and back pain. [7]

Women who are pregnant should not take inebilizumab because it may cause harm to a developing fetus or newborn baby. [7] The FDA advises health care professionals to inform females of reproductive age to use effective contraception during treatment with inebilizumab and for six months after the last dose. [7]

Vaccination with live-attenuated or live vaccines is not recommended during treatment and should be administered at least four weeks prior to initiation of inebilizumab. [7]

History

Inebilizumab was created from the research led by Thomas Tedder at Cellective Therapeutics, [12] and development was continued by Viela Bio and MedImmune. [13]

Inebilizumab was approved for medical use in the United States in June 2020. [7] [9]

The effectiveness of inebilizumab for the treatment of NMOSD was demonstrated in a clinical study (NCT02200770) of 230 adult participants that evaluated the efficacy and safety of intravenous inebilizumab. [7] In the trial, 213 of the 230 participants had antibodies against AQP4 (anti-AQP4 antibody positive). [7] [9] During the 197-day study, the risk of an NMOSD relapse in the 161 anti-AQP4 antibody positive participants who were treated with inebilizumab was reduced by 77% when compared to the placebo treatment group. [7] There was no evidence of a benefit in participants who were anti-AQP4 antibody negative. [7] The primary efficacy endpoint was the time to the onset of the first adjudicated relapse on or before study day 197 evaluated by a blinded, independent, adjudication committee, who determined whether the attack met protocol-defined criteria. [9] The trial was conducted at 82 sites in 24 countries (including the United States) in North and South America, Europe, Africa, Asia and Australia. [9]

The U.S. Food and Drug Administration (FDA) granted the application for inebilizumab orphan drug designation and granted approval of Uplizna to Viela Bio. [7]

Society and culture

In November 2021, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Uplizna, intended for the treatment of adults with neuromyelitis optica spectrum disorders (NMOSD) who are anti-aquaporin 4 immunoglobulin G (AQP4-IgG) seropositive. [14] The applicant for this medicinal product is Viela Bio. [14] Inebilizumab was approved for medical use in the European Union in April 2022. [6] [15]

Names

Inebilizumab is the international nonproprietary name (INN) and the United States Adopted Name (USAN). [16] [17]

Neuromyelitis optica spectrum disorders (NMOSD) are a spectrum of autoimmune diseases characterized by acute inflammation of the optic nerve and the spinal cord (myelitis). Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients.

<span class="mw-page-title-main">Aquaporin-4</span> Protein-coding gene in the species Homo sapiens

Aquaporin-4, also known as AQP-4, is a water channel protein encoded by the AQP4 gene in humans. AQP-4 belongs to the aquaporin family of integral membrane proteins that conduct water through the cell membrane. A limited number of aquaporins are found within the central nervous system (CNS): AQP1, 3, 4, 5, 8, 9, and 11, but more exclusive representation of AQP1, 4, and 9 are found in the brain and spinal cord. AQP4 shows the largest presence in the cerebellum and spinal cord grey matter. In the CNS, AQP4 is the most prevalent aquaporin channel, specifically located at the perimicrovessel astrocyte foot processes, glia limitans, and ependyma. In addition, this channel is commonly found facilitating water movement near cerebrospinal fluid and vasculature.

Eculizumab, sold under the brand name Soliris among others, is a recombinant humanized monoclonal antibody used to treat paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), generalized myasthenia gravis, and neuromyelitis optica. In people with PNH, it reduces both the destruction of red blood cells and need for blood transfusion, but does not appear to affect the risk of death. Eculizumab was the first drug approved for each of its uses, and its approval was granted based on small trials. It is given by intravenous infusion.

Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process. IDDs share characteristics with and are often grouped together under Multiple Sclerosis. They are sometimes considered different diseases from Multiple Sclerosis, but considered by others to form a spectrum differing only in terms of chronicity, severity, and clinical course.

Ocrelizumab, sold under the brand name Ocrevus, is a medication used for the treatment of multiple sclerosis (MS). It is a humanized anti-CD20 monoclonal antibody. It targets CD20 marker on B lymphocytes and is an immunosuppressive drug. Ocrelizumab binds to an epitope that overlaps with the epitope to which rituximab binds.

Tocilizumab, sold under the brand name Actemra among others, is an immunosuppressive drug, used for the treatment of rheumatoid arthritis, systemic juvenile idiopathic arthritis, a severe form of arthritis in children, and COVID‑19. It is a humanized monoclonal antibody against the interleukin-6 receptor (IL-6R). Interleukin 6 (IL-6) is a cytokine that plays an important role in immune response and is implicated in the pathogenesis of many diseases, such as autoimmune diseases, multiple myeloma and prostate cancer. Tocilizumab was jointly developed by Osaka University and Chugai, and was licensed in 2003 by Hoffmann-La Roche.

Research in multiple sclerosis may find new pathways to interact with the disease, improve function, curtail attacks, or limit the progression of the underlying disease. Many treatments already in clinical trials involve drugs that are used in other diseases or medications that have not been designed specifically for multiple sclerosis. There are also trials involving the combination of drugs that are already in use for multiple sclerosis. Finally, there are also many basic investigations that try to understand better the disease and in the future may help to find new treatments.
