General information

Class/mechanism: Antibody-cytotoxic agent conjugate. Gemtuzumab ozogamicin is comprised of a recombinant humanized IgG4 kappa antibody against CD33--an adhesion protein expressed on the surface of leukemic blasts and immature normal cells of myelomonocytic lineage, but not on normal hematopoietic stem cells--conjugated with a cytotoxic agent, calicheamicin. The antibody-cytotoxic agent is internalized after binding, and the calicheamicin derivative binds to DNA in the minor groove, causing DNA double strand breaks and cell death.[1][2]
Route: IV
Extravasation: no information

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]

Diseases for which it is used

Gemtuzumab ozogamicin was withdrawn from the market from 2010-2017; these references will be moved back to active page(s). To be completed.
