Breast Cancer Home > Who Makes Herceptin?

The prescription medicine Herceptin® (trastuzumab) is approved to treat certain types of breast cancer or stomach cancer in adults. It is currently available as a brand-name medication only. Herceptin is made by Genentech, Inc., and it belongs to a group of medications called monoclonal antibodies.
This drug is designed to bind to a specific protein (called HER2) on the outside of certain cancer cells. When Herceptin binds to these proteins, it prevents the cancer cells from growing and multiplying. This medication can also signal the immune system to destroy the cancer cells.
