Generic name: tremelimumab-actl

What is Imjudo?

  • a type of liver cancer called unresectable hepatocellular carcinoma (uHCC). Imjudo may be used in combination with durvalumab when your uHCC cannot be removed by surgery.
  • a type of lung cancer called non-small cell lung cancer (NSCLC). Imjudo may be used in combination with durvalumab and chemotherapy that contains platinum when your NSCLC:

    • your tumor does not have an abnormal “EGFR” or “ALK” gene.

It is not known if Imjudo is safe and effective in children.
