Is Enhertu a chemotherapy drug?
Yes, Enhertu (Fam-trastuzumab deruxtecan-nxki) is a chemo drug (chemotherapy) and it is also a targeted therapy anti-cancer drug.
Enhertu fights cancer in two ways:
- the antibody (trastuzumab) part is designed to find and attach to the HER2 receptor on cancer cells
- once attached to the receptor the chemotherapy (deruxtecan) part of it is released into the cancer cells which destroys the cancer cells and any surrounding cancer cells
Enhertu has been made by joining two different types of anti-cancer drugs together to make one drug called antibody-drug conjugate (ADC).
Deruxtecan section of Enhertu:
- drug section
- chemotherapy (Cytotoxic to cancer cells)
- destroys the cancer cells and any surrounding cancer cells.
Trastuzumab section of Enhertu:
- is a monoclonal antibody section
- targeted therapy anti-cancer medicine
- is designed to find and attach to the HER2 receptor on cancer cells.

Is letrozole a form of chemotherapy?
Letrozole is not chemotherapy, it is a type of hormone therapy that is used to treat people with breast cancer that is hormone receptor-positive. If your cancer is hormone receptor-negative, then letrozole will not be of any benefit. Traditional chemotherapy agents stop cancer cells from growing, dividing, and making more cells. Letrozole works by blocking the action of the enzyme aromatase, which prevents the body from converting androgens into estrogens. Estrogen is a hormone that causes estrogen receptor-positive (ER+) breast cancer to grow. Letrozole belongs to the class of medicines known as aromatase inhibitors. Continue reading
