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
Herceptin prevents HER2 shedding.2
In Bangladesh Herceptin is approved for the following indications.3
