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 While natalizumab was originally approved by the FDA to treat multiple sclerosis in 2004, it was withdrawn from the market following multiple reports of fatal progressive multifocal leukoencephalopathy (PML).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.
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.
