Why is this medication prescribed?
Brexucabtagene autoleucel is used to treat mantle cell lymphoma (a fast-growing cancer that begins in the cells of the immune system) in adults that has returned or is unresponsive to other treatment(s). Brexucabtagene autoleucel is also used to treat certain acute lymphoblastic leukemia (ALL; also called acute lymphoblastic leukemia and acute lymphatic leukemia; a type of cancer that begins in the white blood cells) in adults that has returned or is unresponsive to other treatment(s). Brexucabtagene autoleucel injection 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?
Brexucabtagene autoleucel comes as a suspension (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a hospital or infusion center. It is usually given over a period of up to 30 minutes as a one-time dose. Before you receive your brexucabtagene autoleucel dose, your doctor or nurse will administer other chemotherapy medications to prepare your body for brexucabtagene autoleucel.
Before your dose of brexucabtagene autoleucel injection is to be given, a sample of your white blood cells will be taken at a cell collection center using a procedure called leukapheresis (a process that removes white blood cells from the body). Because this medication is made from your own cells, it must be given only to you. It is important to be on time and to not to miss your scheduled cell collection appointment(s) or to receive your treatment dose. If you are being treated for mantle cell lymphoma, your healthcare provider will check you daily for at least 7 days after you receive your brexucabtagene autoleucel dose to monitor you for any side effects. If you are being treated for ALL, your healthcare provider will check you daily for at least 14 days after you receive your brexucabtagene autoleucel dose to monitor you for any side effects. You should also plan to stay near where you received your brexucabtagene autoleucel treatment for at least 4 weeks after your dose. Your healthcare provider will check to see if your treatment is working and monitor you for any possible side effects. Talk to your doctor about how to prepare for leukapheresis and what to expect during and after the procedure.
