Lifileucel Injection

Brand Name(s): Amtagvi®

WHY is this medicine prescribed?

Lifileucel injection is used treat certain types of melanoma (skin cancer) that have either spread to other parts of the body or are unable to be remove surgically and have not responded to other treatments. Lifileucel is in a class of medications called autologous cellular immunotherapy, a type of medication prepared using cells from the patient's own blood. It works by causing the body's immune system (a group of cells, tissues, and organs that protects the body from attack by bacteria, viruses, cancer cells, and other substances that cause disease) to fight the cancer cells.

HOW should this medicine be used?

Lifileucel comes as a suspension (liquid) to be injected into a vein by a doctor or nurse at a hospital. Your dose of lifileucel will be made from cells retrieved from your surgically removed tumor tissue and sent to a manufacturing center. It will take 34 days for your dose of lifileucel to be made and ready to be given to you. Your doctor will give you chemotherapy medications for 2 days about 5 days before you are scheduled to receive lifileucel to help prepare your body for lifileucel therapy. Right before you are given lifileucel, you will be given several medications to help prevent some of the side effects from lifileucel. You will need to stay in the hospital for several days after receiving lifileucel and then should plan to stay in the immediate area of where you received lifileucel for several weeks.

It is important to be on time and not to miss any scheduled appointments for cell collection or to receive lifileucel injection.
