Humanized IgG1 kappa isotype monoclonal antibody that binds to human CD11a. Efalizumab has a molecular weight of approximately 150 kilodaltons and is produced in a Chinese hamster ovary mammalian cell expression system in a nutrient medium containing the antibiotic gentamicin. The FDA approved efalizumab in 2003. It was later withdrawn in 2009 due to a potential risk of progressive multifocal leukoencephalopathy (PML).
Inappropriate growth of or self-directed antibody production by B-cells is the etiological underpinning of a variety of conditions, including the multiple sclerosis-like neurological condition neuromyelitis optica spectrum disorder (NMOSD).[A214283, A214286] Inebilizumab is a humanized afucosylated monoclonal IgG1 antibody directed against the broadly expressed B-cell surface antigen CD19. Inebilizumab is cytolytic, resulting in B-cell depletion and offering therapeutic benefit to patients suffering from NMOSD. Compared to the anti-CD20 antibody [rituximab], which is also used to treat NMOSD, inebilizumab has broader specificity.[A214280, A214289, A214292, A214295, A214298, A214301] Inebilizumab was granted FDA approval on June 11, 2020, for the treatment of anti-aquaporin 4 positive NMOSD patients. Given its mechanism of action and good safety profile, it may prove useful in the treatment of other conditions linked to autoimmune antibody production or B-cell malignancies.[A214280, A214295] On January 16, 2024, Iinebilizumab also received Health Canada approval for the same indication.
