Herceptin (trastuzumab)

Information on this site is not intended as medical advice and should not be used as a substitute for consulting with qualified doctor.

Trastuzumab is a recombinant humanised monoclonal antibody that selectively targets the extracellular domain of the Human Epidermal growth factor Receptor 2 protein (HER2). HER2 protein exists on normal cells and HER2+ tumor cells. It is believed to block downstream signaling pathways. Herceptin flags the tumor cell for destruction by the body's immune system, known as antibody dependent cellular cytotoxicity (ADCC).1
