## What is blinatumomab?

Blinatumomab is a cancer treatment for adults and children with certain types of acute lymphoblastic leukemia (ALL). ALL is a cancer of the blood which has one type of white blood cell that is growing out of control.

Blinatumomab is a monoclonal antibody which is a type of "targeted" cancer therapy. It targets specific proteins on the surface of the cancer cells. This tells your immune system to find and destroy cancer cells, which helps you to live longer.

Monoclonal antibodies only target specific cells so they may be less toxic to healthy cells.

- B-cell precursor acute lymphoblastic leukemia (ALL) which is in remission with molecular evidence of leukemia
