Atezolizumab Injection

Atezolizumab injection is used alone or with other chemotherapy medications to treat certain types of non-small cell lung cancer (NSCLC) in adults. Atezolizumab injection is also used in combination with other chemotherapy medications to treat certain types of small cell lung cancer (SCLC), hepatocellular carcinoma (HCC), and melanoma (a type of skin cancer) in adults. Atezolizumab is also used alone to treat certain types of alveolar soft tissue sarcomas (cancer that forms in muscles, fat, or nerves) in adults and children 2 years of age or older. Atezolizumab injection is in a class of medications called monoclonal antibodies. It works by blocking the action of a certain protein in cancer cells. This helps the person’s immune system to fight against the cancer cells, and helps to slow tumor growth.

Your doctor will review your specific type of cancer and past treatment history and other available treatments to determine if atezolizumab injection is right for you.
