Description: Sapitinib, also known as AZD-8931, is an erbB receptor tyrosine kinase inhibitor with potential antineoplastic activity. erbB kinase inhibitor AZD8931 binds to and inhibits erbB tyrosine receptor kinases, which may result in the inhibition of cellular proliferation and angiogenesis in tumors expressing erbB. The erbB protein family, also called the epidermal growth factor receptor (EGFR) family, plays major roles in tumor cell proliferation and tumor vascularization.

Biological target: Sapitinib (AZD-8931) is a reversible, ATP competitive EGFR inhibitor of with IC50s of 4, 3 and 4 nM for EGFR, ErbB2 and ErbB3 in cells, respectively.
In vitro activity: The effects of blocking HER3 on CRC tumor growth were further determined by the subQ xenograft tumor model with treatment of the HER3 inhibitor AZD8931. After HCP-1 cells were injected subQ in the mixture of CM and Matrigel as described above, mice were then treated with either vehicle or AZD8931 by gavage and the tumor growth was monitored over time (Fig. 6). These results showed that LPEC-1 CM treated tumors led to significantly greater tumor growth, as expected. More importantly, AZD8931 significantly inhibited the tumor growth in both CRC CM and LPEC-1 CM-treated CRC tumors compared with tumors without AZD8931 treatment (Fig. 6B). In addition, CRC tumors that were treated by AZD8931 had significantly lower tumor weight compared with tumors not treated with AZD8931, leading to ~2-fold decrease compared to CRC CM treated tumors, and > 4-fold decrease compared to LPEC-1 CM treated tumors (Fig. 6C).

In vivo activity: When tumors reached 40–50 mm3 (~ 16 days), mice were treated daily with AZD8931 (50 mg/kg) or diluent by oral gavage. As shown in Fig. 3a, treatment with AZD8931 rapidly halts B4B8 tumor progression and causes significant shrinkage of tumors (Fig. 3b) compared to tumor-bearing mice treated with diluent as a control. Thus, B4B8 cells serve as a murine HNSCC model to explore EGFR/ERBB-dependent growth in an in vivo setting.
