Introduction of Nectin-4 Targets

Nectin-4, also known as poliovirus receptor-related protein 4 (PVRL4), is a transmembrane protein belonging to the nectin family of immunoglobulin-like molecules. This family consists of four members (nectin-1 to -4), which play important physiologic roles in multiple homeostatic and developmental processes through their involvement in cellular adhesion, differentiation, proliferation, migration, and immunemodulatory signaling. Multiple studies have provided evidences that Nectin-4 is linked with carcinogenesis and disease severity of a cancer patient. Nectin-4 has been established as a novel biomarker for the worst prognosis in cancer and associated with different facets of tumor including proliferation, angiogenesis, metastasis, tumor relapse, DNA repair etc. Additionally, Nectin-4 has been found to be highly expressed in several malignancies, such as bladder, breast, lung, pancreatic, ovarian, head & neck, and esophageal, supporting the rationale for its use as a target antigen for ADCs.

Clinical ADC Therapy Targeting Nectin-4

Development of ADCs for the treatment of urothelial carcinoma is led by enfortumab vedotin (EV), which consists of a fully human monoclonal antibody targeting Nectin-4 that binds to a microtubule inhibitor MMAE via a cleavable linker. DAR analysis indicated that approximately 3.8 MMAE molecules are conjugated through cysteines via the same cleavable linker technology. Mechanistically, binding of EV to the Ig-like loops (IgV and IgC loops) of Nectin-4 leads to the stimulation of complex internalization and lysosome mediated cleavage of valine-citrulline linker. Therefore, MMAE is released in target cells to bind to microtubules and enhance microtubule breakdown, ultimately playing a major role in anticancer.
