Idecabtagene Vicleucel Injection

WHY is this medicine prescribed?

Idecabtagene vicleucel injection is used to treat certain types of multiple myeloma (a type of cancer of the bone marrow) in adults whose cancer has returned or is unresponsive to at least four other treatments. Idecabtagene vicleucel 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?

Idecabtagene vicleucel injection comes as a suspension (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a doctor's office or infusion center. It is usually given over a total period of up to 30 minutes as a one-time dose. Before you receive your idecabtagene vicleucel dose, your doctor or nurse will administer other chemotherapy medications to prepare your body for idecabtagene vicleucel.

Before your dose of idecabtagene vicleucel 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. You should plan to stay within 2 hours of the location where you received your idecabtagene vicleucel 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.
