Nectin-4

Target

Nectin-4 is a type I transmembrane protein and a member of the nectin glycoprotein family.3 Nectin-4 is primarily expressed in the placenta during fetal development and is weakly expressed in some adult human tissues, such as skin.3,4 Overexpression of Nectin-4 has been observed in several solid tumor types including urothelial, breast, cervix, lung, and ovarian cancers,2,4 and is associated with promoting tumor proliferation and metastasis.3 The higher expression of Nectin-4 in tumor cells compared to normal cells makes the protein an ideal target for tumor-specific delivery of cytotoxic agents via an antibody-drug conjugate (ADC).3

Molecule
LY4101174 is a next-generation anti-Nectin-4 targeting ADC. It is comprised of a humanized IgG1 Fc-silent monoclonal Nectin-4 antibody linked to the topoisomerase I inhibitor, exatecan, via a maleimide-B-glucuronide poly-sarcosine linker with a homogeneous drug-antibody ratio (DAR) of 8:1. In preclinical in vivo models, LY4101174 has shown antitumor activity across a range of Nectin-4 expression levels including a Nectin-4 MMAE ADC resistant model.
Clinical Development

LY4101174 is being investigated in a global open-label, multicenter, phase 1a/1b study in patients with advanced or metastatic urothelial carcinoma and select solid tumors.
