Nerlynx is a prescription drug approved by the U.S. Food and Drug Administration (FDA) as adjuvant (post-surgery) treatment for adults with early stage breast cancer in which HER2 is overexpressed or amplified. Nerlynx is indicated for extended use after therapy with trastuzumab. Nerlynx is also referred to by its drug name, neratinib.
In about 25 percent of breast cancers, there is a genetic variation that causes tumor cells to produce extra receptors for a growth factor. This gene, known as HER2 or human epidermal growth factor receptor 2, causes the cancer to grow more aggressively. Nerlynx is a member of a class of drugs called kinase inhibitors, and it is designed to inhibit the growth of cancer cells with the HER2 gene. Nerlynx is believed to work by interfering with the growth of HER2-positive cancer cells, thereby slowing the growth of tumors.
