Lifileucel is used to treat a certain type of skin cancer (melanoma) that has not gotten better or that has come back after other kinds of treatment. Lifileucel is made from your own white blood cells found in your tumor and is given only to you. The white blood cells help your body slow or stop the growth of certain cancer cells.

Your doctor will give you 7 days of chemotherapy before treatment with lifileucel to prepare your body. After receiving lifileucel, you will be given another medication to help lifileucel work better.
