Herceptin which is a monoclonal antibody, is used for treatment of metastatic breast cancer because it is a biological response modifier that boosts the immune system while targeting only breast cancer cells.
Herceptin works by binding to the HER2 surface receptors of breast cancer cells, restricting them from receiving growth signals. Herceptin can slow as well as stop the growth of breast cancer by obstructing the signals. An example of immune targeted therapy is Herceptin.
Herceptin treatment typically lasts one year, unless side effects become unbearable. Herceptin is only administered intravenously (IV).
A monoclonal antibody is one that is derived from a cell line created by cloning a specific white blood cell. All subsequent antibodies derived in this manner can be traced back to a single parent cell. Monoclonal antibodies have monovalent affinity, which means they only bind to the same epitope.
