Durvalumab Overview
-
Durvalumab is used alone to treat non-small cell lung cancer (NSCLC) that spread to nearby tissues and cannot be removed by surgery but has not worsened after being treated with other chemotherapy medications and radiation treatments. It is also used in combination with tremelimumab-actl (Imjudo) and platinum-based chemotherapy to treat a certain type of NSCLC that has spread throughout the lungs and to other parts of the body. Durvalumab injection is also used in combination with chemotherapy agents to treat extensive-stage small cell lung cancer (ES-SCLC) in adults whose cancer has spread throughout the lungs and to other parts of the body. It is also used in combination with chemotherapy agents to treat biliary tract cancer (BTC; cancer in the organs and ducts that make and store bile, the liquid made by the liver) in adults whose cancer has spread to nearby tissues or to other parts of the body. Durvalumab is also used in combination with tremelimumab-actl to treat hepatocellular carcinoma (HCC; a type of liver cancer) that cannot be treated with surgery. Durvalumab injection is in a class of medications called monoclonal antibodies. It works by helping your immune system to slow or stop the growth of cancer cells.
