DescriptionAfatinib is a tyrosine kinase inhibitor which is a 4-anilinoquinazoline. It is prepared has the dimaleate salt. FDA approved on July 12, 2013.
SaltsAfatinib dimaleate
Brand Names
  • Gilotrif
  • Giotrif
Affected OrganismHumans and other mammals
IndicationAfatinib is a kinase inhibitor indicated for the first-line treatment of patient with metastatic non-small cell lung cancer (NSCLC) whose tumours have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L858R) substitution mutations as detected by an FDA-approved test.
PharmacologyAfatinib did not effect the QTc interval.
Mechanism of actionAfatinib is an irreversible kinase inhibitor and binds to the kinase domains of EGFR (ErbB1), HER2 (ErbB2), and HER4 (ErbB4) to inhibit tyrosine kinase autophosphorylation. This results in a downregulation of ErbB signalling and subsequent inhibition of proliferation of cell lines expressing wild-type EGFR, selected EGFR exon 19 deletion mutations, or exon 21 L858R mutations. It also inhibited in vitro proliferation of cell lines overexpressing HER2. Overall, tumour growth was inhibited.
