Important Safety Information

What is the most important information I should know about IMFINZI® (durvalumab)?

IMFINZI is a medicine that may treat certain cancers by working with your immune system. IMFINZI can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

What is IMFINZI?

IMFINZI is a prescription medicine used to treat adults with a type of cancer called biliary tract cancer (BTC), including cancer of the bile ducts (cholangiocarcinoma) and gallbladder cancer. IMFINZI may be used in combination with chemotherapy medicines gemcitabine and cisplatin when your BTC has spread to nearby tissues (locally advanced), or has spread to other parts of the body (metastatic).

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