Betibeglogene autotemcel Injection

Betibeglogene autotemcel injection is used to treat anemia (a lower than normal number of red blood cells) in people who require regular blood transfusions to treat beta thalassemia (Cooley’s anemia; an inherited condition that causes a low number of red blood cells). Betibeglogene autotemcel injection is in a class of medications called autologous gene therapy, a type of medication prepared using cells from the patient’s own blood stem cells. It works by helping your body to produce enough red blood cells so that regular blood transfusions are not necessary.

🔔 How should this medicine be used?

Betibeglogene autotemcel injection comes as a suspension (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a hospital. Betibeglogene autotemcel injection is given as a one-time dose administered over up to 2 hours. Before you receive your betibeglogene autotemcel dose, your doctor or nurse will administer other chemotherapy medications to prepare your body for betibeglogene autotemcel.

Before your dose of betibeglogene 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 betibeglogene autotemcel injection. It will take about 70–90 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.

You will have to stay in the hospital for about 3–6 weeks after you receive your betibeglogene 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.

Betibeglogene autotemcel injection may cause infusion reactions, which may occur within 24 hours of receiving your dose. Tell your doctor or nurse if you experience any of the following symptoms: fast or irregular heartbeat or stomach pain.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
