Uses for Besponsa
Inotuzumab ozogamicin injection is used to treat acute lymphoblastic leukemia (ALL) that has come back or after other medicines did not work well. Leukemia is a type of cancer where the body makes abnormal white blood cells.

Before you begin treatment, talk to your doctor about the benefits of this medicine as well as the possible risks of using it.
