Atezolizumab is a humanized monoclonal antibody used to prevent the interaction of PD-L1 and PD-1, removing inhibition of immune responses seen in some cancers.[A18493,L7489] This medication is reserved for patients whose tumors express PD-L1, cannot receive platinum-based chemotherapy, or whose tumors do not respond to platinum-based chemotherapy. Atezolizumab was granted FDA approval on 18 October 2016. In November 2022, the manufacturer (Genentech) voluntarily withdrew the use of atezolizumab for the treatment of urothelial carcinoma, previously approved under the FDA's Accelerated Approval Program. The rest of atezolizumab indications remain unaffected.
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]
