Natalizumab is a recombinant humanized IgG4κ monoclonal antibody that binds to α4-integrin. While natalizumab was originally approved by the FDA to treat multiple sclerosis in 2004, it was withdrawn from the market following multiple reports of fatal progressive multifocal leukoencephalopathy (PML). In 2006, the FDA reintroduced the drug to the market for multiple sclerosis. Natalizumab was further approved by the FDA for the treatment of Crohn's Disease in January 2008. On August 24, 2023, the first biosimilar to natalizumab, natalizumab-sztn, was approved by the FDA. Natalizumab was approved by the European Commission on September 22, 2023.
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 mood swings. MS is one of the most common causes of neurological disability in young adults and is found to occur more frequently in women than in men.[A176474,L5792]
