Nerlynx (neratinib) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Nerlynx is used alone or with other medicines to treat early-stage HER2-positive breast cancer. Nerlynx is also used to treat HER2-positive breast cancer that is advanced or has spread to other parts of the body (metastatic).
Nerlynx is used for breast cancer only if your tumor tests positive for a protein called human epidermal growth factor receptor 2 (HER2). HER2 protein can speed the growth of cancer cells.
Nerlynx is usually given after you have been treated with another medicine called trastuzumab (Herceptin).
