What does Oplusituzumab/Ointuzumab for injection (Besponsa) do?

Besponsa/Besponsa is a drug used to treat acute lymphoblastic leukemia (ALL). ALL is a malignant blood disease that usually originates in lymphocytes, a type of white blood cells that normally help the body fight infections. However, ALL occurs when lymphocytes undergo malignant changes and proliferate rapidly. These abnormal cells are unable to perform normal immune functions and interfere with the production of normal blood cells, including red blood cells, white blood cells, and platelets. Intuzumab and intuzumab belong to a class of drugs called monoclonal antibodies. Its mechanism of action is to interfere with the growth and survival of leukemia cells by targeting the CD22 antigen.
