Trastuzumab emtansine, a conjugate of trastuzumab with a DM1 microtubule inhibitor, provides direct intracellular delivery of the potent cytotoxin DM1 to HER2-overexpressing cells while retaining trastuzumab activity. It is currently approved in the Czech Republic for the treatment of patients with early or metastatic breast cancer.
