Siponimod, also known as _Mayzent_, by Novartis, is a new drug formulated for the management of Multiple Sclerosis (MS). It was approved by the FDA on March 26, 2019 and by Health Canada on February 20, 2020. This drug is considered a _sphingosine-1-phosphate (S1P) receptor modulator_ and is thought to play a role in suppressing the central nervous system inflammation that is associated with MS [FDA label]. Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system that is chronic and inflammatory, disrupting communication between the brain and other parts of the body. Most patients diagnosed with this illness experience their initial disease symptoms between the age of 20 to 40, often the most productive years of life. Symptoms may include but are not limited to fatigue, gait changes, bowel or bladder dysfunction, abnormal muscle twitching, vision disturbance, and depressing or
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.
