Description: Poziotinib , also known as HM781-36B and NOV120101, is an orally bioavailable, quinazoline-based pan epidermal growth factor receptor (EGFR or HER) inhibitor with potential antineoplastic activity. HM781-36B irreversibly inhibits EGFR (HER1 or ErbB1), including EGFR mutants, HER2, and HER4, thereby inhibiting the proliferation of tumor cells that overexpress these receptors. EGFRs, cell surface receptor tyrosine kinases, are often upregulated in a variety of cancer cell types and play key roles in cellular proliferation and survival.

| Biological target: | Poziotinib (HM781-36B) is a pan-HER inhibitor, which effectively inhibits EGFRwt, HER-2 and HER-4 with IC50s of 3.2, 5.3 and 23.5 nM, respectively. |
| In vitro activity: | Poziotinib, a pan-human epidermal growth factor receptor (HER) inhibitor, decreased sphere formation, viability, and proliferation, and induced G1 cell cycle arrest and apoptosis in ovarian CSCs (cancer stem cells). In addition, poziotinib suppressed stemness and disrupted downstream signaling of Wnt/β-catenin, Notch, and Hedgehog pathways, which contribute to many characteristics of CSCs. Interestingly, HER4 was overexpressed in ovarian CSCs and Poziotinib reduced the phosphorylation of STAT5, AKT, and ERK, which are regulated by HER4.

| In vivo activity: | The in vivo activity of HM781-36B was assessed in xenograft mice models with various EGFR-dependent cancer cell lines. Daily oral treatments of HM781-36B at 0.3 mg/kg/day or 1 mg/kg/day for 10 days resulted in a dramatic reduction of tumor size with an 83% maximum inhibition rate (mIR, IR = [1 − (relative tumor growth in treated group/relative tumor growth in control group)] × 100) at 0.3 mg/kg/day without body-weight loss. The effect of HM781-36B on HCC827 tumor endothelium was evaluated by immunohistochemistry and a significant reduction in the expression level of pEGFR, pAKT and pERK was observed upon treatment with HM781-36B (0.3 mg/kg/day) for 10 days (Fig. 3b).
