Ado-trastuzumab emtansine is used in the treatment of breast cancer and metastatic breast cancer. It is indicated for certain types of breast cancer that are positive for human epidermal growth factor receptor 2 (HER-2) and have spread to other organs, particularly in cases that have not responded to other cancer therapies.
How Ado-trastuzumab emtansine works Ado-trastuzumab emtansine is an anti-cancer medication. It binds to HER2 receptors on breast cancer cells, marking them for destruction by the body's immune system. Additionally, it enters the cancer cells to release a chemotherapy agent (emtansine), inhibiting their growth and division.
Common side effects of Ado-trastuzumab emtansine include tiredness, nausea, musculoskeletal pain (bone, muscle, or joint), bleeding, low blood platelets, headache, liver disorder, constipation, and nosebleeds.
