Besponsa® (inotuzumab ozogamicin)
for Leukemia

Besponsa (inotuzumab ozogamicin) is a biological therapy used to treat CD22-positive B-cell acute lymphoblastic leukemia (ALL) in patients aged 1 year and older. It’s an antibody-drug conjugate combining an antibody targeting CD22—a protein on B-cell leukemia cells—with calicheamicin, a cytotoxic agent. Once inside cancer cells, calicheamicin damages DNA, causing cell death and reducing leukemia growth.
