Description: Varlitinib, also known as ARRY-543 and ASLAN001, is an orally bioavailable inhibitor of the epidermal growth factor receptor family with potential antineoplastic activity. Varlitinib selectively and reversibly binds to both EGFR (ErbB-1) and Her-2/neu (ErbB-2) and prevents their phosphorylation and activation, which may result in inhibition of the associated signal transduction pathways, inhibition of cellular proliferation and cell death. EGFR and Her-2 play important roles in cell proliferation and differentiation and are upregulated in various human tumor cell types.

ARRY-543 is a novel, oral ErbB family inhibitor that, unlike approved ErbB inhibitors, targets all members of the ErbB family, including ErbB3, either directly or indirectly, and has potential advantages in treating tumors that signal through multiple ErbB family members. ARRY-543 showed benefit in preclinical tumor models that signal through multiple ErbB family members, as well as its efficacy in preclinical models when compared to, and combined with, Herceptin (trastuzumab), Xeloda (capecitabine) and Taxotere (docetaxel) – widely used treatments for solid tumors.
