Mechanism of Action
Inotuzumab ozogamicin is comprised of cytotoxic antibiotic N-acetyl-gamma-calicheamicin dimethylhydrazide attached to a humanized monoclonal IgG4 antibody via 4-(4 acetylphenoxy) butanoic acid (acetyl butyrate) linker. The drug exerts a potent cytotoxic effect against CD22+ B-cell lymphoma when the antibody binds to the CD22 receptor on the surface of B cells . The drug-CD22 complex is rapidly internalized into the cell, forming an endosome which subsequently fuses with lysosomes. N-acetyl-gamma-calicheamicin dimethylhydrazide is then intracellularly released into the acidic environment. N-acetyl-gamma-calicheamicin dimethylhydrazide is a calicheamicin derivative, which is naturally produced by the bacterium Micromonospora echinospora, and is toxic to the body when not bound to the antibody. It mediates apoptosis of the cell by binding to the minor groove of DNA in a sequence-specific manner and undergoing a structural change to generate diradicals [A20354]. These changes abstract hydrogen ions from the phosphodiester bonds of double-stranded DNA, resulting in breaks and cell apoptosis [A3883, A3884, A20352].
