Exagamglogene Autotemcel Injection

What is this medication?

EXAGAMGLOGENE AUTOTEMCEL (ex GAM gloe jeen AW toe TEM sel) treats sickle cell disease. It may also be used to treat beta thalassemia. It works by helping your body make healthy red blood cells. These cells do not sickle. This can reduce symptoms of sickle cell disease, such as pain crises. Healthy red blood cells also reduce the need for blood transfusions in people with beta thalassemia.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.

How should I use this medication?

This medication is infused into a vein. It is given by your care team in a hospital or clinic setting.

This therapy uses your own stem cells. Your care team will give you other medications as part of your treatment. Before therapy, your care team will give you a medication that helps move your stem cells from your bone marrow to the blood stream, so they can collect them. This is called mobilization. These cells will be used to make your treatment. Shortly before you receive treatment, you will receive another medication that helps prepare your body for the stem cell transplant. This is called conditioning.
