產(chǎn)品描述：

The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer. Dacomitinib (PF-00299804) is an irreversible small molecule pan-HER inhibitor.

In vitro: Dacomitinib reduced the phosphorylation of HER2, EGFR, HER4, AKT, andERKin the majority of sensitive lines. Dacomitinib exerted its antiproliferative effect through a combined G0–G1 arrest and an induction of apoptosis. Dacomitinib inhibited growth in several HER2-amplified lines with de novo and acquired resistance to trastuzumab. Dacomitinib maintained a high activity in lines with acquired resistance to lapatinib. This study identifies HER2-amplified breast cancer lines as most sensitive to the antiproliferative effect of dacomitinib and provides a strong rationale for its clinical testing in HER2-amplified breast cancers resistant to trastuzumab and lapatinib [1].

In vivo: To evaluate the in vivo efficacy of PF00299804, the authors generated xenografts in nu/nu mice using HCC827 GFP and HCC827 Del/T790M cells and treated the mice with PF00299804. PF00299804 effectively inhibited the growth of HCC827 GFP xenografts. PF00299804 treatment was substantially more effective at inhibiting growth of this xenograft model than gefinitib. Thus, these preclinical models suggest that PF00299804 may be quite effective against lung cancers that become resistant to gefitinib or erlotinib via acquisition of a T790M mutation in EGFR [2].

Clinical trial: Dacomitinib (PF-00299804) is an experimental drug candidate under development by Pfizer for the treatment of non-small-cell lung carcinoma. It is a selective and irreversible inhibitor of EGFR. Dacomitinib has advanced to several Phase III clinical trials. The results of the first trials were disappointing, with a failure to meet the study goals. Additional Phase III trials are ongoing (http://en.wikipedia.org/wiki/Dacomitinib).
