Tofacitinib is an inhibitor of Janus kinases, a group of intracellular enzymes involved in signalling pathways that affect hematopoiesis and immune cell function. It is approved by the FDA for treatment of moderate to severe rheumatoid arthritis that responds inadequately to methotrexate or in those who are intolerant to methotrexate. Besides rheumatoid arthritis, tofacitinib has also been studied in clinical trials for the prevention of organ transplant rejection, and is currently under investigation for the treatment of psoriasis. Known adverse effects include nausea and headache as well as more serious immunologic and hematological adverse effects. Tofacitinib is marketed under the brand name Xeljanz by Pfizer.
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.
