Why is this medicine prescribed?
Elivaldogene autotemcel injection is used to slow the progression of brain damage and slow the decline of nerve function in males 4–17 years of age with early, active cerebral adrenoleukodystrophy (CALD; an inherited condition in which fatty acids build up in the brain, resulting in nerve and brain damage). Elivaldogene autotemcel 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 helping your body to break down the fatty acids and slow the progression of nerve and brain damage.
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Elivaldogene autotemcel injection comes as a suspension (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a hospital. Elivaldogene autotemcel injection is given as a one-time dose, which is contained in 1 or 2 infusion bags. Each infusion bag is usually given over no more than 60 minutes. Before you receive your elivaldogene autotemcel dose, your doctor or nurse will administer other chemotherapy medications to prepare your body for elivaldogene autotemcel.
Before your dose of elivaldogene autotemcel injection is to be given, a sample of your blood stem cells will be taken at a hospital or treatment center using a process called mobilization and apheresis (a process that removes blood stem cells from the body). This process usually takes about 1 week and may need to be repeated. The sample will be sent to the manufacturer to prepare a dose of elivaldogene autotemcel injection. It will take about 51–65 days from the time that your blood stem cells are collected before they are ready to be given to you. Because this medication is made from your own cells, it must be given only to you.
Elivaldogene autotemcel injection may cause nausea and vomiting during treatment with the medication. Your doctor may give you other medications to help prevent nausea and vomiting.
You will have to stay in the hospital for about 2 months after you receive your elivaldogene autotemcel dose to monitor you for any side effects. Talk to your doctor about how to prepare for mobilization and apheresis and what to expect during and after the procedure.
