CAR T-Cell Treatment for Leukemia
Engineering a Smarter, Stronger Immune System
The immune system is your bodys security system. It fights off anything that doesnt belong, namely, viruses, bacteria, fungi and toxins.
White blood cells are an essential part of the immune system. They form in your bone marrow (the spongy material inside bones). One type of white blood cell is called a lymphocyte. There are two types of lymphocytes:
- B-cells: B-cells are the brains of the operation. They find invading enemies and send in reinforcements the T-cells to stop them.
- T-cells: The T-cells are the muscle. They destroy the targets that the B-cells found.
In acute lymphoblastic leukemia (ALL), cancer affects how these lymphocytes develop so they cant do their job right. But with CAR T-cell therapy for leukemia, doctors reprogram the healthy T-cells to kill leukemia cells.
How CAR T-Cell Treatment for Leukemia Works
CAR T-cell therapy is a revolutionary new treatment for leukemia. It is a combination of gene therapy and immunotherapy.
During leukemia CAR T-cell therapy:
- Doctors draw your childs blood to get their T-cells.
- Using gene therapy, they reprogram the T-cells to make the CAR protein. The CAR protein makes it possible for them to recognize and attack only cancer cells. This process takes about a month.
- Doctors then multiply the changed T-cells in a laboratory.
- Some patients get chemotherapy while waiting for their new T-cells. The chemotherapy lessens the amount of leukemia in their body to prepare it for the new cells.
- When there are enough T-cells, doctors give the changed cells back to your child intravenously (through an IV).
Once in your childs body, the new T-cells grow in number and get rid of the cancer. And because these cells stay in your childs body for months, maybe years, they may provide long-term protection.

CAR T-Cell Therapy vs. Bone Marrow Transplant
Both bone marrow transplants (also known as stem cell transplants) and CAR T-cell therapy effectively treat childhood leukemia. But there are some differences.
Doctors can use bone marrow transplants to treat several types of childhood leukemia, including ALL, acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). Currently, doctors can only use CAR T-cell therapy to treat B-cell ALL. B-cell ALL is the most common type of leukemia that relapses.
CAR T-cell therapy tends to have fewer side effects than stem cell transplants because:
- Kids receive lower doses of chemotherapy.
- It involves the patients own cells not a donors. Using your childs own cells lowers the risk for complications like graft-versus-host disease, where the immune system attacks the patient's healthy cells.
Who Can Get Leukemia CAR T-Cell Therapy?
Because of ongoing leukemia clinical trials, the list of children who can get CAR T-cell therapy grows each year. Children with other kinds of leukemia or lymphoma may also be able to get this therapy in the future as we continue to prove its safety and effectiveness.
In 2017, the FDA approved the use of CAR T-cell therapy in children with B-cell ALL that has relapsed. If your child has been diagnosed with B-cell ALL that has relapsed or not responded to other treatments, they may be eligible for CAR T-cell therapy.
