Relapsed/Refractory B-cell Acute Lymphoblastic Leukemia

What is B-cell acute lymphoblastic leukemia?

B cells are defenders of your body. Along with other cells, they make up your body’s adaptive immune system. When B cells become cancerous, they can grow out of control and cause a type of blood cancer called B-cell acute lymphoblastic leukemia (ALL).

B-cell ALL is the most common form of pediatric leukemia. While many children with leukemia get better after their first treatment, some may not. 

In the past, the only choices for children and young adults with relapsed or refractory B-cell ALL have been chemotherapy or stem cell transplant. But there is now a different treatment option with KYMRIAH® (tisagenlecleucel).
