What is Herceptin, and what does the name mean?
Herceptin is the brand name for trastuzumab, a monoclonal antibody used to treat HER2-positive cancers. The “HER2” part refers to a protein called human epidermal growth factor receptor 2, which can drive tumor growth in some breast and stomach (gastric) cancers. [1]
Quick “glossary-style” terms patients and caregivers see with Herceptin
HER2-positive
A cancer status meaning tumor cells test positive for overexpression and/or amplification of the HER2 protein. This status is used to decide whether anti-HER2 treatments like Herceptin are appropriate. [1]
Monoclonal antibody (mAb)
A lab-made protein designed to bind to a specific target—in Herceptin’s case, the HER2 receptor on cancer cells. [1]
Trastuzumab
The generic name of Herceptin. [1]
Dosing (IV infusion or injection in some settings)
Herceptin is given by healthcare professionals as an infusion or other delivery method depending on the specific regimen approved/used. [1]
Common companion testing
HER2 testing is central—without it, Herceptin generally isn’t used because the drug is aimed at HER2-driven disease. [1]
What HER2 status is required to use Herceptin?
Herceptin is used for tumors that are HER2-positive. That HER2 result comes from pathology tests on tumor tissue (and sometimes other approved testing approaches), which determine whether the cancer has the HER2 features targeted by trastuzumab. [1]
How does Herceptin work (plain-English mechanism)?
Herceptin (trastuzumab) binds to the HER2 receptor on cancer cells, helping slow or stop tumor growth driven by HER2 signaling. [1]
What cancers is Herceptin used for?
Herceptin is used in HER2-positive settings including breast cancer and stomach (gastric) cancer, as supported by its labeled indications. [1]
Is Herceptin the only HER2 drug? What’s different from other anti-HER2 therapies?
Herceptin (trastuzumab) targets HER2 directly. Other HER2 therapies may target the HER2 receptor in different ways or combine antibody action with chemotherapy or other mechanisms. Patients usually see these differences when choosing between treatment options for specific cancer types, stages, and prior therapies. [1]
