1. What IMFINZI is and what it is used for

IMFINZI is used to treat a type of lung cancer called non-small cell lung cancer (NSCLC) in adults. It is used when your NSCLC:

  • has spread within your lung and cannot be removed by surgery, and
  • has responded or stabilised after initial treatment with chemotherapy and radiotherapy

It is used in combination with platinum-based chemotherapy prior to surgery (neoadjuvant treatment) and alone after surgery (adjuvant treatment) when your NSCLC:

  • has spread within your lung and is able to be removed by surgery.

IMFINZI in combination with chemotherapy is used to treat a type of lung cancer called extensive-stage small cell lung cancer (ES-SCLC) in adults. It is used when your SCLC:

  • has spread within your lungs (or to other parts of the body) and
  • has not previously been treated.

IMFINZI in combination with chemotherapy is used in adults to treat a type of cancer of the bile ducts (cholangiocarcinoma) and gallbladder that are collectively referred to as biliary tract cancers (BTC). It is used when your BTC:

  • has spread within your bile ducts and gallbladder (or to other parts of the body).

IMFINZI in combination with tremelimumab is used to treat a type of liver cancer called advanced or unresectable hepatocellular carcinoma (HCC) in adults. It is used when your HCC:

  • cannot be removed by surgery (unresectable), and
  • may have spread within your liver or to other parts of the body.

IMFINZI contains the active substance durvalumab which is a monoclonal antibody, a type of protein designed to recognise a specific target substance in the body. IMFINZI works by helping your immune system fight your cancer.

If you have any questions about how IMFINZI works or why this medicine has been prescribed for you, ask your doctor or pharmacist.

When IMFINZI is given in combination with other anti-cancer medicines, it is important that you also read the package leaflet for these other medicines. If you have any questions about these medicines, ask your doctor.

2. What you need to know before you are given IMFINZI
You should not be given IMFINZI
  • if you are allergic to durvalumab or any of the other ingredients of this medicine (listed in section 6 “Contents of the pack and other information”). Talk to your doctor if you are not sure.
