Mechanism of action:

Xovoltib (Afatinib) is a protein kinase inhibitor that also irreversibly inhibits human epidermal growth factor receptor 2 and epidermal growth factor receptor (EGFR) kinases. Xovoltib (Afatinib) is not only active against EGFR mutations targeted by first generation TKIs like erlotinib or gefitinib, but also against mutations such as T790M which are not sensitive to these standard therapies. Because of its additional activity against receptor 2, it is being investigated for breast cancer as well as other EGFR and receptor 2 driven cancers.
