What is Herceptin (Trastuzumab)?
Herceptin® is the originator brand for trastuzumab, developed by Genentech/Roche. It is prescribed in the management of cancers that test positive for the HER2 protein, including certain breast cancers and metastatic stomach cancers. It is a prescription-only medicine given under specialist supervision, usually by infusion.
How Trastuzumab works
Trastuzumab is a monoclonal antibody that attaches to the HER2 protein found in larger amounts on the surface of some cancer cells. By targeting HER2, it is used as part of a treatment plan directed by your oncologist. HER2 testing is performed first, because the medicine is intended for HER2-positive tumours.
