General information

Class/mechanism: Antibody-cytotoxic agent conjugate consisting of the HER2 humanized IgG1 kappa monoclonal antibody Trastuzumab (Herceptin) linked with a small molecule microtubule inhibitor and maytansine derivative, emtansine (DM1). The humanized monoclonal antibody binds to subdomain IV of the HER2 receptor, is subjected to receptor-mediated endocytosis, and lysosomal degradation leads to the intracellular release of DM1. DM1 binds to tubulin at the rhizoxin binding site, inhibits the assembly of microtubules, and leads to cell cycle arrest and cell death via apoptosis. Similar to Trastuzumab (Herceptin), ado-trastuzumab emtansine inhibits HER2 receptor signaling, facilitates antibody-dependent cell-mediated cytotoxicity (ADCC), and inhibits shedding of the HER2 extracellular domain in HER2-overexpressing human breast cancer cells.[1][2][3][4][5][6]
Route: IV
Extravasation: irritant

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, Medscape,UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
