NERLYNX® (neratinib) is a once-daily oral medicine for women who have just finished trastuzumab therapy (i.e., Herceptin®) following surgery for early-stage breast cancer.

NERLYNX is the first HER2-targeted treatment approved by the FDA to further reduce the risk of recurrence after Herceptin. Talk with your healthcare team to decide if the treatment is right for you.

nerlynx, an anti-her2
targeted therapy extended adjuvant therapy

NERLYNX: A different kind of treatment

NERLYNX is an oral, extended adjuvant therapy, meaning it is designed to be taken after your adjuvant Herceptin treatment (following surgery). NERLYNX targets HER2+ breast cancer in a different way by working inside the cell to block the pathways that can lead to tumor growth.

How NERLYNX may help

Normally, HER2 receptors on healthy cells send signals to tell the cells when to grow. In HER2+ breast cancer, some cancer cells have too many HER2 receptors. These cells grow and divide uncontrollably.

Other HER2 treatments may work by interfering with HER2 receptors from outside the cell. NERLYNX interacts with multiple HER family receptors inside the cell to block multiple growth pathways. This alters the signals that lead to cancer growth.
