NCIt definition : A CD22-targeted cytotoxic immunoconjugate composed of a humanized IgG4 anti-CD22 antibody
covalently linked to N-acetyl-gamma-calicheamicin dimethyl hydrazide (CalichDMH) with
potential antineoplastic activity. Inotuzumab ozogamicin is rapidly internalized upon
binding of the antibody moiety to B cell-specific CD22 receptors, delivering the conjugated
CalichDMH intracellularly; the CalichDMH moiety binds to the minor groove of DNA in
a sequence-specific manner, resulting in double-strand DNA breaks and apoptosis. CalichDMH
is a derivative of gamma calicheamicin, a cytotoxic antibiotic produced by the bacterium
Micromonospora echinospora.;
