What is Trastuzumab emtansine
Trastuzumab emtansine, formerly called Trastuzumab-DM1 (T-DM1) is a first-in-class HER2 antibody drug conjugate (ADC) comprised of Genentech’s trastuzumab antibody linked to ImmunoGen’s cell-killing agent, DM1. T-DM1 combines two strategies– anti-HER2 activity and targeted intracellular delivery of the potent anti-microtubule agent, DM1 (a maytansine derivative)–to produce cell cycle arrest and apoptosis. Trastuzumab emtansine is marketed under the brand name Kadcyla and is indicated for use in HER2-positive, metastatic breast cancer patients who have already used taxane and/or trastuzumab for metastatic disease or had their cancer recur within 6 months of adjuvant treatment. The FDA label has two precautions. First that trastuzumab emtansine and trastuzumab cannot be interchanged. Second that there is a black box warning of serious side effects such as hepatotoxicity, embryo-fetal toxicity, and cardiac toxicity.
Trastuzumab emtansine mechanism of action
Trastuzumab emtansine is a HER2 antibody drug conjugate. The antibody portion is trastuzumab, which is humanized anti-HER2 IgG1, and produced in the mammalian Chinese Hamster Ovary cells. The drug portion is DM1, which is a maytansine derivative that inhibits microtubules. These two portions are covalently connected by 4-[N-maleimidomethyl]cyclohexane-1-carboxylate (MCC), which is a stable thioether linker. Together MCC and DM1 are called emtansine and are produced by chemical synthesis. Trastuzumab emtansine binds to the HER2 receptor sub-domain IV and goes into the cell by receptor-mediated endocytosis. Lysosomes degrade trastuzumab emtansine and release DM1. DM1 binds to tubulin in microtubules and inhibits microtubule function producing cell arrest and apoptosis. As well, similar to trastuzumab, in vitro studies have shown that both HER2 receptor signalling inhibition and antibody-dependent cytotoxicity are mediated by trastuzumab emtansine.
