Description
Atezolizumab, sold under the brand name Tecentriq, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), triple-negative breast cancer (TNBC), small cell lung cancer (SCLC), and hepatocellular carcinoma (HCC). It is a fully humanized, engineered monoclonal antibody of IgG1 isotype against the protein programmed cell death-ligand 1 (PD-L1).
In May 2016, the FDA granted accelerated approval to atezolizumab for locally advanced or metastatic urothelial carcinoma treatment after failure of cisplatin-based chemotherapy. The confirmatory trial (to convert the accelerated approval into a full approval) failed to achieve its primary endpoint of overall survival. In 2018, FDA altered the use of atezolizumab as a first-line treatment for metastatic bladder cancer in people who can’t receive cisplatin-based chemotherapy and have high levels of PD-L1.
In October 2016, FDA approved atezolizumab for the treatment of people with metastatic non-small cell lung cancer (NSCLC) whose disease progressed during or following platinum-containing chemotherapy. People with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving atezolizumab.
Atezolizumab is also used to treat extensive stage small cell lung cancer.
In March 2019, the FDA approved atezolizumab for the treatment of people with triple-negative breast cancer.
