GIOTRIF is a medicine which contains the active substance afatinib. It works by blocking the activity of a group of proteins called the ErbB family (including EGFR [epidermal growth factor receptor or ErbB1], HER2 [ErbB2], ErbB3 and ErbB4). These proteins are involved in the growth and spread of cancer cells,
and can be affected by changes (mutations) in the genes that produce them. By blocking the activity of these proteins this medicine can inhibit growth and spread of cancer cells.
This medicine is used on its own to treat adult patients with a specific type of cancer of the lung (non-small cell lung cancer): * that is identified by a change (mutation) in the gene for EGFR. GIOTRIF can be prescribed to you as your first treatment or if prior chemotherapy treatment has been insufficient. * of squamous type if prior chemotherapy treatment has been insufficient.
