Dacomitinib is an oral, once-daily, pan-HER inhibitor. It is an irreversible inhibitor of HER-1 (EGFR), HER-2 and HER-4 tyrosine kinases. Dacomtinib is being evaluated in phase 3 clinical trials against nonsmall-cell lung cancer. Direct comparison with erlotinib did not show superiority of dacomtinib, but subgroup analysis have demonstrated that subgroup with exon 19 deletion had favorable outcomes with dacomitinib. In addition to nonsmall-cell lung cancer dacomtinib is being evaluated against esophagus, head and neck and other neoplasms. Due to its ability to pass through blood-brain barrier, dacomitinib can be used to treat brain tumors.

Sample Use Guides
In phase III study against non small cell lung cancer dacomitinib was administered orally at a dose 45 mg a day.
Route of Administration:
Oral
Cells were seeded in duplicate at 5 × 103 to 5 × 104 cells per well in 24-well plates. A day after plating, dacomitinib was added at 10 μmol/L and 2-fold dilutions over 12 concentrations were carried out to generate a dose–response curve. Control wells without the drug were also seeded. The cells were counted on day 1 when the drug was added, as well as after 6 days when the experiment ended. After the trypsinization cells were placed in an Isotone solution and immediately counted using a Coulter Z1 particle counter (Beckman Coulter, Inc.). The suspension cultures were counted using a Coulter Vi-Cell counter (Beckman Coulter, Inc.). As a group, HER2-amplified cell lines were most sensitive to growth inhibition by dacomitinib (IC50 < 1 μmol/L in 14 of 16 lines).
