Consumer Medicine Information (CMI)

This leaflet provides important information about using Giotrif. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about taking Giotrif.

Where to find information in this leaflet:

1. Why am I taking Giotrif?

Giotrif contains the active ingredient afatinib dimaleate. Giotrif belongs to a group of medicines called antineoplastic (or anti-cancer) agents.

It works by blocking the activity of a group of proteins from the ErbB family, which includes a protein called Epidermal Growth Factor Receptor (EGFR). These proteins are known to be involved in the growth and spread of cancer cells. By blocking the activity of these proteins Giotrif stops the cancer cells from growing and multiplying.

Giotrif is used to treat adult patients with a type of lung cancer called non-small cell lung cancer (NSCLC):

• of non-squamous type identified with a change (mutation) in the gene for EGFR. Giotrif can be prescribed to you as your first treatment or if your cancer has progressed after receiving chemotherapy
• of squamous type if your cancer has progressed after receiving chemotherapy.
