Boehringer Ingelheim
Afatinib*, a Boehringer Ingelheim investigational compound, is an irreversible blocker of the ErbB-Family.1
How does ErbB-Family signalling work?
Signals from receptors of the ErbB-Family inform cells to perform normal cell functions such as multiply or differentiate as shown below with the ErbB1 receptor.2
Disregulated activation of ErbB-signalling in cancer cells
Cancer cells can mutate and therefore dysregulate normal signalling processes leading to an abnormal continuous signaling, resulting in a higher rate of cell division and tumour growth.3
ErbB-Family receptors are frequently overexpressed on cancer cell surfaces. Overexpression of ErbB-Family receptors such as EGFR and HER2 has been associated with a variety of tumour types and is associated with
poor prognosis and advanced-stage cancer.2-4
Mode of action of afatinib* – targeting the ErbB-Family1
Since ErbB-receptor family signalling can be initiated by a variety of homo- and heterodimers, an irreversible inhibition of all ErbB-Family members may provide a more successful blockade of the ErbB-Family signalling. Afatinib* acts on all ErbB-Family receptors, therefore blocking the key pathways involved in cell growth.
