Axicabtagene ciloleucel is used to treat a certain type of cancer (non-Hodgkin lymphoma). This type of treatment is known as gene therapy. Axicabtagene ciloleucel is made from your own white blood cells and is given only to you. The white blood cells have been changed to have a specific protein (chimeric antigen receptor-CAR) that helps your body slow or stop the growth of certain cancer cells.

Tell your doctor right away if you develop unusual growths or lumps, swollen glands, signs of infection (such as a sore throat that doesn't go away, fever, chills), easy or unusual bruising/bleeding, or unusual tiredness.
