Definition

A drug that binds to the protein PD-L1 to help immune cells kill cancer cells better and is used to treat different types of cancer, including cancers that express PD-L1. Tecentriq is used alone or with other drugs to treat adults with certain types of hepatocellular carcinoma (a type of liver cancer), melanoma, non-small cell lung cancer, or small cell lung cancer. It is also used alone to treat adults and children aged 2 years and older with alveolar soft part sarcoma that has spread to other parts of the body or cannot be removed by surgery. It is also being studied in the treatment of other types of cancer. Tecentriq may block PD-L1 and help the immune system kill cancer cells. It is a type of monoclonal antibody and a type of immune checkpoint inhibitor. Also called atezolizumab.
