Claudin 18.2 targeting T-cell engager

CompoundAZD5863

Area under investigation

Advanced solid tumors

Scientific PillarT-Cell Engager

Target Overview

Claudin 18.2 (CLDN18.2), an essential component of tight junctions in gastric epithelium, is highly expressed in gastric, pancreatic and esophageal adenocarcinoma.1 CLDN18.2 is a validated therapeutic target in CLDN18.2-high gastric cancer.2-4

Compound Overview

AZD5863 is a CLDN18.2- and CD3-targeting T cell engager designed with bivalent high-affinity binding to CLDN18.2 and monovalent low-affinity binding to CD3 to reduce class-associated toxicities (eg, CRS), while maintaining potent and specific antitumor activity. AZD5863 has been demonstrated to induce T cell mediated killing of CLDN18.2 expressing cells of gastric, pancreatic and esophageal cancer origin in in vitro and in vivo models, and to induce bystander killing of neighboring CLDN18.2 negative cells, expanding its use to a wider patient population.5
