What is Imjudo?

Imjudo is a prescription medicine that may be used in combination with Imfinzi (durvalumab) to treat adults with unresectable hepatocellular carcinoma or non-small cell lung cancer (NSCLC) that has spread (metastatic NSCLC).

Imjudo is a human monoclonal antibody that works by blocking the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4).

What is Imjudo used to treat?

Imjudo is used in combination with durvalumab to treat hepatocellular carcinoma, the most common type of primary liver cancer.

• The risk of hepatocellular carcinoma is higher in people who have long-term liver diseases, liver scarring from hepatitis B or hepatitis C infection, those who drink large amounts of alcohol, and those who have an accumulation of fat in the liver.

Imjudo may also be used in combination with durvalumab and platinum-based chemotherapy for the treatment of adult patients with metastatic NSCLC with no sensitizing epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) genomic tumor aberrations.

It is not known if this medicine is safe and effective in children.
