Trastuzumab emtansine (Ado-Trastuzumab emtansine) is an antibody-drug conjugate (ADC) that incorporates the HER2-targeted antitumor properties of trastuzumab with the cytotoxic activity of the microtubule-inhibitory agent DM1 (derivative of maytansine). Trastuzumab emtansine can be used for the research of advanced breast cancer[1][2].

Trastuzumab emtansine (2 μg/mL; 3 d) significantly inhibits the proliferation of epithelial ovarian cancer (EOC) cells[2].

Trastuzumab emtansine (15 mg/kg; i.v. three to five times weekly for 3 weeks) exhibits significantly anti-tumor effect in mice[2]. Animal Model: CB-17/SCID mice (6 weeks) were injected with OVA10 cells[2]
