atezolizumab
(A-teh-zoh-LIZ-yoo-mab)
A drug used to treat certain types of non-small cell lung cancer and urothelial cancer (a type of bladder cancer) that have advanced or spread to other parts of the body. It is used in patients whose disease cannot be treated with or has gotten worse during or after treatment with anticancer drugs that included platinum. It is also being studied in the treatment of other types of cancer. Atezolizumab binds to a protein called PD-L1, which is found on some cancer cells. Atezolizumab may block this protein and help the immune system kill cancer cells. It is a type of monoclonal antibody and a type of immune checkpoint inhibitor. Also called Tecentriq.
