The monoclonal antibody portion of vadastuximab talirine specifically binds to the cell surface antigen CD33. This causes the internalization of SGN-CD33A, and the release of the cytotoxic moiety SGD-1882. SGD-1882 binds to and crosslinks DNA, which results in both cell cycle arrest and the induction of apoptosis in CD33-expressing tumor cells. CD33, a transmembrane receptor, is expressed on myeloid leukemia cells."}]
