LY-4052031

Product Description

LY4052031 is a fully human monoclonal anti-Nectin-4 antibody conjugated to a novel TOPO 1 inhibitor by a cleavable peptide linker at a homogeneous drug antibody ratio (DAR) of 8:1. In vitro, both LY4052031 and its unconjugated parental antibody specifically bind to Nectin-4 expressing cell lines and are quickly and efficiently internalized. LY4052031 demonstrated potent cytotoxicity on tumor cells with high and low Nectin-4 expression. Additionally, bystander activity exerted by LY4052031 on antigen negative cells co-cultured with antigen positive cells was greater than that observed with the clinical benchmark enfortumab vedotin-ejfv. In vivo studies in xenografts expressing low to high levels of Nectin-4 showed significant tumor growth inhibition following treatment with LY4052031 as monotherapy. Overall, LY4052031 exhibits specificity, selectivity, potency, and effectiveness as a next generation therapy to treat Nectin-4 positive tumors. An IND submission is planned for 2024.
