About treatment

TYKERB^® (lapatinib) tablets is designed to inhibit HER2 receptors

HER2 is a type of protein found on normal cells as well as breast cancer cells
In women with HER2+ breast cancer, the breast cancer cells have too many HER2 receptors (designated as HER2+)
When these HER2 receptors join together, they direct cancer cells to grow and divide

TYKERB works inside cancer cells to block HER2 receptors

TYKERB is a small molecule that passes through the surface of cells and may help block HER2 receptor activity
Once inside the cell, TYKERB binds to the HER2 protein receptor inside the cell

When tested in animals and in human breast cancer cells grown outside the body, TYKERB blocked HER2 receptors and cell growth.
