title: Antibody-targeted chemotherapy with immunoconjugates of calicheamicin.
abstract: Targeted delivery of cytotoxic agents to tumours is believed to improve both their anti-tumour efficacy and their safety. Antibodies specific for tumour-associated antigens have been used to deliver cytotoxic agents to tumour cells. Calicheamicin is a potent cytotoxic agent that causes double-strand DNA breaks, resulting in cell death. When conjugated to monoclonal antibodies specific for tumour-associated antigens, calicheamicin exerts strong antigen-specific anti-tumour effects against human tumour xenografts in preclinical models. Antibody-targeted chemotherapy with immunoconjugates of calicheamicin, exemplified by gemtuzumab ozogamicin (Mylotarg), is a clinically validated therapeutic strategy for the treatment of human cancer.
