Tarceva (also called Erlotinib) is used to treat people with Non-small cell lung cancer, whose cancer has come back after or not responded to another treatment, such as chemotherapy. It is also being used to treat other types of cancers that have come back or spread, in clinical trials.
You may hear your doctor refer to Tarceva as an EGFRs (epidermal growth factor receptors) inhibitor. These type of drugs aim to kill cancer cells while causing little harm to surrounding normal cells.
Epidermal growth factor receptors (EGFRs) are on the surface of many types of cancer cells. They allow epidermal growth factor (a type of protein) to attach to them. When this happens, a kinase (a type of protein which plays a role in regulating how a cell works and grows) is activated, triggering the cell to grow and multiply.
Tarceva works by attaching itself to the kinase and in this way interrupts the cancer cell from growing and dividing.
Your doctor will test your cancer cells taken from biopsy or surgery to check the levels of EGFR. This will help predict whether or not your cancer will respond to Tarceva.
Tarceva is a tablet.
It is taken by mouth in the morning with a glass of water, either an hour before or after a meal.
Tarceva can cause a rash, especially on the face, chest and back. This usually appears within two weeks of starting treatment. It is important to tell your doctor if you get a rash so that they can monitor you. It should improve within a few weeks even if you are still on treatment.
