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. 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.
Atezolizumab has approved indications for the following conditions:
Non-Small Cell Lung Cancer (NSCLC)
Small Cell Lung Cancer (SCLC)
Hepatocellular Carcinoma (HCC)
Melanoma
Alveolar Soft Part Sarcoma (ASPS)
